SECRETS OF TABOO POND

At Christmas, Mom said, more than asked, "Pete, I'm going to need your help over your Spring Break to go up to the cabin, open it up for spring and put the docks in the pond, assuming the ice has melted. I know you were hoping to go to Cancun with your college buddies, but now that your grandfather is gone, I can't manage it alone and your sisters have their Spring Break too early, before the ice could possibly be melted."

Claire and Megan looked unusually pleased about not having to help Mom with this task.

"Sure, Mom," I responded, trying to keep the disappointment out of my voice. I loved the cabin in the summer but had never done the spring prep before. It had been tradition that Mom and Grandpa Jack Conroy did it the last full week of March, but he had died just before Thanksgiving, leaving Mom the property in his will. He had lived with us since I was ten, when both my father Tom Minosky and Grandma May had passed away in the same year. He became my replacement dad in many ways, basically co-parenting with my mom. Whose name is Barbara, by the way.

All I could think was that the water was going to be extremely cold, getting the floating docks in. I never quite understood why it had to be done so soon after the ice melted, since we didn't usually start staying there until Memorial Day. Whenever I had asked, Grandpa's answer was that he wanted to do the spring opening early so he could get any needed repairs handled before the holiday and installing the docks was just part of that process to him.

~~~~~

I got out of my last class on Friday, March 22nd, and drove my car the 100 miles from my school to home, getting there after dark at 8 PM. Mom gave me a very warm hug at the door, her soft breasts pressing into my chest. I couldn't help imagining what they would feel like in my hands and mentally slapped myself for it, like I always did whenever I had sexual thoughts about her or my sisters.

Mom had a baked chicken dinner ready for us. I was surprised to see a bottle of wine on the table, so asked, "What's the occasion? You hardly ever serve wine with dinner."

She responded, "Only if I've got someone to drink it with. This is the first dinner you and I have had together since you turned 21 that didn't also have your sisters here. I didn't think it was fair to invite you to share wine with me and deny Claire and Megan because they're only 19. Unless you'd rather have one of those hard ciders you left in the fridge after Christmas break?"

"Wine's fine, Mom."

As we ate, she said, "I think we ought to leave around 8 tomorrow. I've got most of Grandpa's SUV packed already, except for food that needs to go into the cooler and whatever clothes you'll need. Don't forget a bathing suit, unless you want to put the dock in naked." The smile on her face as she said that made me briefly wonder whether she was picturing us doing just that, but I dismissed it.

We watched a little TV after dinner, sitting together on the couch. Gradually, Mom got closer and closer, until she was leaning against my side, her head on my shoulder. Was Mom really cuddling with me? Or had I simply watched too many porn clips where step-mom and step-son wind up having sex? I tried to dismiss those thoughts. This was my mom, not a step-mom and not some porn actress pretending that another unrelated performer is her son.

I couldn't get that idea out of my mind when I went to bed, though. I found myself imagining one of those porn scenes, but with Mom and I in the roles. Picturing her riding my cock in a cowgirl position, my hands holding her glorious boobs, led to a throbbing erection that wouldn't go away on its own.

I jerked off, trying to get that mental image out of my head while I did it and failing completely. I wanted to imagine fucking my mom, even while it made me feel vaguely guilty and abnormal. It wasn't the first time I had pictured her and I was sure it wouldn't be the last, but usually I could shift my mental imagery to someone else. That night, I couldn't. To avoid lingering on her for too long, I began stroking faster, to reach orgasm as quickly as I could. At least I didn't moan her name loudly as I came or anything that would make Mom aware of what I was doing. I kept quiet as my orgasm hit and cum blasted across my stomach and chest. I cleaned it up with a tissue and settled down to sleep.

My last thought was that Mom and I would be alone at the cabin for a week.

~~~~~

The cabin, while built with logs, wasn't as rustic as the word sounds, being a two-story house with three bedrooms and two baths, built atop a cement foundation set into the side of a hill, with an open side facing the water. The main entrance to the house was on the uphill side. A deck faced the pond, with another entrance into the basement area below it. A cabana containing a hot tub was built on the left side of the deck, a set of stairs down to the ground at the right end.

Another small bedroom was set up in the basement, which was usually mine, along with laundry, utilities and storage. However, I expected I would be sleeping in one of the upstairs bedrooms during this stay.

Electricity was provided by solar panels both on the roof and on the south-facing hillside away from the pond, with reserve battery storage to bridge night time and cloudy days. A lone telephone line was our one outside utility. Heat was a combination of an in-floor heating system that was left running just enough in the winter to avoid freezing its own pipes, plus a stone fireplace and a small wood stove in the basement that tied into the same chimney. Mostly, those were only needed in the spring and early fall, before we closed up for winter. While the roads to access the property stayed open in the snows, we had rarely used the cabin in the winter, just a couple years where we spent Christmas through New Years there, then winterized it again until Spring.

When we arrived at 9:30, we could see that the pond was 80% open water, with ice still on the opposite shore, where trees shaded it. While the air temperature outside was already 59F, the inside temperature was just 45F, so my first task was to get a fire lit in the fireplace, while Mom moved around opening drapes to let the sun in. Then we turned on the water pump to the well and let water flow back into the pipes and connected the hose to refill the hot tub on the deck.

After getting the food cooler inside and unloaded, we started on removing the storm windows, first removing plywood which covered the french doors into the basement, so we could access the storage area. We pulled out the sections for the dock to make room for storing the windows, then took down the plywood over the sliding glass doors on the deck and removed the windows that could be reached from the ground or deck, carrying each to the storage area. Before tackling the ones on the 2nd floor via ladder, we broke for lunch, also turning on the hot tub heater and adding spa chemicals as it had filled. The inside temperature had risen to 60F, so we turned up the thermostat for the in-floor heating to 65F, turned on the house's water heater and added more wood to the fire.

By the time we got the upper floor's storm windows off and stored in the basement, it was 2 PM. The outside temp had risen to 69F. It looked like the ice across the pond had shrunk just from the air's warmth battling the water's cold.

Mom asked, "Are you ready to tackle installing the docks? The weather forecast is for cooler weather the rest of the week, maybe even some rain. We won't get a better day for it."

"We're still going to freeze our butts off, since the ice hasn't finished melting," I grumbled.

"You'll find it invigorating, honey," she said, grinning. "Trust me."

After changing into bathing suits, we carried the three dock sections the rest of the way to the water's edge. The docks were basically wooden platforms with empty plastic barrels secured underneath to act like pontoons, with hardware to connect the sections together. We slid the first section between the two metal poles driven into the shore that anchored the system and got it fastened without having to get in the water.

Mom said, "Now, we need to wade out to fasten the other sections. They have to float to line up and it won't work if we lay on top of them."

"Mom, I may not have put them in before, but I have helped take them out. I understand how it works."

As I stepped into the still-frigid water on the left side, pushing the second section ahead of me, my skin began to tingle and I actually felt warmer than I expected.

Moving the section around the end of the first to where Mom was waiting, we got it lined up and secured the two together. We were in waist deep water by then and the weird tingling sensation reached my groin and I found myself getting hard involuntarily. Or maybe it was seeing Mom's stiff nipples poking through her one-piece bathing suit.

I tried hiding my stiff cock as I climbed out of the water to get the third section, but Mom was looking right at my groin, like she knew what was going to happen. I was too flustered to ask any questions. I then floated the third section out, turned it 90 degrees so it formed a T and we got it attached, now in chest-high water. Rather than wade back into shore, Mom ducked herself under the water, then pulled herself up onto the dock and lay back, her head toward me.

My eyes locked again on her hard nipples poking through her suit and the cleavage exposed to me. My cock throbbed even harder and I found myself climbing onto the dock next to her and lay on my back, letting the sun reheat my skin as it continued to tingle. The muscle fatigue I had been feeling from everything we'd been carrying around was entirely gone and I felt energized in a way I'd never felt before.

I jumped when I felt Mom's hand stroke along my still-hard cock, but I did nothing to stop her as she untied the top of my trunks and reached her chilly hand inside. Before I knew it, the trunks were off and my cock was deep in her hot mouth. A small piece of me knew intellectually that I should be objecting, but most of me wanted her to continue. To fulfill the fantasies I had. It just felt too good to do anything but moan. My mom was blowing my cock!

I watched as she reached a hand into the water and scooped some into her mouth, then slipped her lips over my cock without letting any of the water escape. The tingling effect intensified as she slowly rose up and down, her tongue swirling the water around and around my ultra-sensitive glans.

"God, Mom, that's so hot," I finally managed to say, realizing as I said it how I never expected those words to come from my mouth in terms of her.

She managed to shimmy her bathing suit off while still bobbing up and down on my cock. My eyes roamed her body as it was exposed. Her breasts were more amazing than I'd imagined, her waist taut and hips flared out into an hourglass figure.

I didn't resist when she let my cock free, swallowed the last of the water in her mouth, I'm sure mixed with my pre-cum, and climbed over me. She looked down at me, eyes sparkling, and asked, "Do you want this, Pete?"

"Yes, more than anything," I answered, surprising myself at how easily I was overruling the taboo my mind said I should be feeling about sex with my mom, which seemed to be completely gone emotionally. I wanted to fuck her, more than I'd wanted any other woman.

"I love you Pete, in all ways," she said, as she notched my cock between her labia and lowered herself onto me. She kept eye contact with me as our groins met and she paused there, rocking a little to grind her clit against my groin.

"I love you too, Mom," I replied, just before she rose up several inches and dropped again. The pleasure was so intense, I gasped. I grabbed her hips and started to thrust into her from below. To fulfill my fantasy from the night before, I reached up and grasped her breasts, her nipples hard in my palms. We slapped into each other for fifteen minutes, not getting tired at all.

Mom then dismounted and lay back in the center of the dock section, looking over at me to say, "Fuck me, Pete. Hard as you can. I need it."

I got up and moved over to her. I raised her right leg along my torso and straddled her left, turning her partly onto her side and thrust myself back into her. "Oh, fuck, Mom, you feel so good," I said as I pounded into her at top speed, making the dock rock so much that water began splashing onto us, reinforcing whatever effect it was having on us. The contrast between the cold of the water and the heat of her pussy made this fuck feel like nothing I had ever experienced.

"Yes, yes, yes," she cried, as the water swirled around her. "Oh, I'm cumming, baby! Fuck me! Give me your sperm!" She pulsed around my thrusting cock and I found my own orgasm rushing through me and I exploded in gob after gob of cum into her.

"Fuuuuccckkkk!" I shouted, hearing an echo bounce back to me. Thankfully, we owned all of the land visible from the pond, so there were no witnesses to what we'd just done.

At least, I didn't think so.

Slowing to a stop, I eased out of her, watching my jizz ooze out as I lowered her leg and then collapsed on my back next to her on the wet dock. It felt miraculous that I wasn't at all winded. Still, it took a couple of minutes before I could ask, "What the hell just happened, Mom?"

"Welcome to the secret of the pond, honey."

"What? You knew this was going to happen?" I asked.

"I wanted it and hoped you would too," she answered, rolling to her side to stroke her fingers along my chest as she looked into my eyes. "We've never figured out exactly what makes this pond unique, but something in it produces some kind of aphrodisiac, which concentrates in the water while the pond is covered in ice, then starts to dissipate once the ice melts or once it reaches a certain temperature. Either way, for about the first three weeks after the water is exposed, it has the stronger effect we just experienced. It lowers your inhibitions, seeming to remove the incest taboo, but doesn't seem to create desire where it doesn't already exist. I would not have made a move on you if I hadn't seen that you were reacting to my body and I would have stopped if you asked me. During the summer, the effect is weaker, resulting in only a slight increase in horniness, something you might credit to the fresh air and sunshine.. That's why we didn't bring you here earlier than Memorial Day. "

"You and grandpa put these docks in this same time every year. Are you telling me...?"

"Yes, Pete. The water coaxed Dad and I into becoming lovers when I was your age, the spring we were working on finishing the cabin's interior. Tom and your grandmother May were with us that first time, but otherwise Dad and I only had sex when we were here by ourselves." She paused, a concerned look on her face, as she decided whether to continue. "The other secret I need to admit is that he's your biological father as well as grandfather. I'm also your half-sister."

Part of me was shocked, but my heart immediately told me Mom was telling me the truth. I didn't resemble the Minosky side of the family at all. But my sisters both did, although fraternal twins. "Claire and Megan? Am I right that they're not also Grandpa's daughters?"

Mom answered, "No, they're Tom's daughters. They're both your half-sisters and half-nieces. Shared DNA would be between half and full sisters, if we let you be tested and compared. They discovered the secret of the pond, too. The two of them snuck up here last spring the weekend after Dad and I put the docks in, went swimming and wound up making love here on the dock like we just did. Dad caught them at it when he came to do some repairs, then fucked them both. So far as I know, they were the last lovers he had before he got sick."

"So, they knew what was going to happen between the two of us before I did? No wonder they were smirking at me at Christmas."

Mom shrugged and said, "They knew it was likely once I asked you to come here instead of Cancun, but it was still up to you to choose once you were exposed to the pond. It was all I could do to keep them from showing up this weekend to get their shot at you, in their words."

That's when I felt the dock shift and looked over Mom's shoulder to see my sisters walking hand in hand toward us, naked. "Think again, Mom, they're here."

"Goddammit, girls," Mom grumbled as she spun around, ready to start yelling at them.

Grinning, the pair sprinted, vaulted over us and dove head first into the water, still holding hands. I sat up to watch them, as did Mom, leaning her head on my shoulder. Even the water still in her hair made my skin's nerves react. What was in the water?

Upon surfacing, my sisters--or was it sister-nieces?--were embracing, kissing and squeezing each other's breasts as they treaded water. After a minute, they swam back to the dock and set their elbows on the edge, looking up at us.

"I see the water did its trick, Pete," Claire said, her eyes locked on my cock, which was hardening already. She added, "If you jump back in, you'll be fully recharged in no time. Drink some and you'll be hard all day. Viagra has nothing on this." She scooped some of the water into her mouth and swallowed, matched by Megan. "Too bad the effect doesn't survive being bottled."

I looked from face to face, before asking, "Mom, what should I do?"

"Only what you want to do, honey," she replied. "As I said, the water only unlocks any attraction you are feeling but might otherwise resist. You feel society's incest taboo a lot less, if at all. Making love to me is something you wanted deep down or you would have stopped me. If you really don't want to make love to your sisters, despite their willingness, then don't. They're butting in as it is and they know it."

Megan whined, "But, Mom! If we don't get our chance to be with him now, we'd have to wait another year for the pond to be ready again."

Mom said, "Meg, I just got through saying that the pond doesn't make his decisions for him. Neither do you. If his answer is going to be yes, now that everything is out in the open between the four of us, it would still be a yes in July without needing the pond's effects. But if it's no, that's it. I'm not going to push him into a decision in either direction."

I asked, "Does this mean my incest taboo is gone forever?"

"Seems to work like that," Mom answered.

"So, what is your choice, big brother?" Megan asked.

I answered Megan by rolling forward and bent down to kiss her fully on the lips, causing her to squeal. I then grabbed her under the arms and lifted her onto the dock, then repeated both actions with Claire. By the time I was face to face with Claire on our knees, my hands around her back but itching to knead her butt--her best feature in my opinion--Megan was in a clinch with Mom, kissing her and rubbing their breasts together. Except for Megan's brown hair contrasting with Mom's blond and Mom's breasts resting a little lower on her chest, their physiques matched. Claire was more slender than either, but just as sexy. They all had the blue eyes that I shared with them, that were even more dramatic with wet eyelashes sparkling in the sun.

I kissed Claire again, then asked her, "I've heard Meg say it, but is this what you want, Claire?"

"More than almost anything I've ever wanted, Pete," she answered, before reaching down to caress my renewed cock with a wet hand. "The water does wash away the incest taboo permanently, because it stayed gone between Meg and I even after we went home. Then over the summer I realized that you were the person I wanted to be with most. I love you, big brother."

"And I love you, sweetie," I said, knowing that things would never be the same between all four of us and glad that there was no longer a secret being kept from me. We just had to keep it from the rest of the world.

lowered my hands to her butt and squeezed. Slowly, I licked my way down her neck and chest until I reached her nipples, feeling energy flow into me from the droplets of water I sucked from her skin.

I looked back up into Claire's adoring eyes as I pulled her body closer to mine, her stomach against my ribs and her sweet pussy inches above my hard cock. She nodded to my unasked question and allowed gravity to slide her down my body until my cock made contact, as she wrapped her legs around my hips. She reached between us to position me just right and let me enter her. Our eyes linked as my cock slid into her velvet heat, contrasting the slight chill her skin still held from her dive into the water.

I had never had sex with two women on the same day before and now it was happening with all three women in my family? I almost pinched myself to be sure I wasn't dreaming, but didn't because I didn't want to wake up if I were.

Once I was fully inside her snug pussy, I grasped her taut butt cheeks to help her rise and fall, pulling her down onto me. Gradually, I lowered myself into more of a crouch, my sister sitting on my thighs, as we gyrated our hips against each other, more than thrusting into her. As my knees began to feel the strain, I lowered my ass fully to the cold deck and straightened my legs out, as we converted to a cowgirl position without my pulling free from her.

"Smooth," she muttered as she leaned forward to brace her hands on my shoulders and started to thrust back at me. My hands ranged from her ass to her shoulders before I moved them down to grasp her petite breasts and brought my mouth to her swollen nipples once more.

Claire's vigorous movements transferred to the dock itself, causing more water to slosh over the edge and onto my legs, its energizing effect pulsing through both of us. I imagined the pond was a living participant in our fuck, driving us upward while washing us with some ineffable quality of lust to replenish its mysterious effects. I wondered how many times my mom and grandfather had quenched their lusts for each other in this same spot and how many times I would do the same in the future. Because I knew I'd want to experience this again and again.

"Oh, fuck, Claire!" I groaned, her speed picking up and our pelvises slamming together. I thrust from below as much as I could, but Claire was doing most of the work. I loved letting her be in control, setting our pace. For so much of our lives, she'd been the quiet one compared to Meg and Mom. The energetic lover she was being now felt like a new side of her. One I was glad to know firsthand.

"Fuck, fuck, I'm cumming, Pete!" Her inner muscles clenched around me as she kept thrusting onto me, ever faster. When her whole body started to shake above me, my hands on her chest were what kept her from collapsing onto mine. Her eyes closed, she groaned and moaned through her orgasm, until she slowed to a stop, leaned down to kiss me, then looked to her right at Mom and Megan.

They had settled into a 69, Mom on her back but with one leg trailing over the dock edge so she had her foot in the water. Now that Claire and I weren't causing water to splash, we could hear their soft moans as they licked each other. Claire looked back at me. "Go fuck Meg. You can come in me later." With that, Claire slid off of me, leaving me with my still-hard cock waving in the air.

I rolled back onto my knees and leaned over to scoop a handful of the pond water to my mouth, finding it so much stronger than the small amounts I'd licked from Claire's skin that it warmed my insides instead of feeling icy. The energy flowed to my cock, making it even stiffer. I approached Megan from behind and made eye contact with Mom between my sister's thighs. Mom reached back and fondled my balls and shaft, then helped direct me into Megan's spit-wet slit.

"Oh, Pete, yes! Give it to me!" Megan groaned, as I slid deeply into her with one push. I grabbed onto her hips and began to thrust in and out. 'Pussy number three,' I thought, too delirious with pleasure and fantasy fulfillment to compare them, to think which was tighter or better at grasping my cock. Instead, I felt like I'd always belonged where I was right then, the places society told me were off limits. Inside my mom and sisters. No guilt remained about this being incest.

Mom was sucking at my balls when she wasn't licking Megan and I checked off another item from my bucket list. One I could never make public. At least, not without anonymity, like I'm doing now. As the saying ought to go, all names changed to protect the truly guilty.

I stroked at a steady pace, reaching around to grasp Megan's full breasts. Tweaking her thick nipples made her squeal and mutter, "I'll give you all day to stop that."

"Deal," I said back to her. I indeed felt like I could fuck her all day, but could also feel my second orgasm creeping closer. Still, I wanted her to come before I did, not knowing how many times Mom might have already taken her into nirvana.

I thrust faster, trying my best to angle my cock to hit her gspot and must have succeeded, as she started to grunt louder and louder with each stroke.

"Mom! Oh, god, yes!" she cried out, as her body bucked between Mom and me. Mom had clearly latched onto Megan's clit. I pinched both of Megan's nipples and she screamed and came as hard as I'd ever seen a woman orgasm, shaking and writhing. Had I not been holding onto her, I think she might have shaken herself off the dock.

Her inner muscles clenched around me and pushed me over my edge and I grunted, "Cuummmmminnggg!" and filled Megan's pussy to overflowing. Mom's tongue scooped up what was squirting out. When I withdrew, Claire was right there to suck the combined juices from my cock, while Mom continued licking Megan's pussy to get what I'd left behind, even though Megan was all but unconscious at that point.

"We're going to kill each other at this rate," I mumbled, as my cock was staying hard in Claire's mouth, just as she had said it would.

"But what a way to go," Claire responded, finally letting my cock out of her mouth, although she kept stroking it. "But I suppose we ought to take a break. It's starting to get colder and the pond water won't keep us warm enough to stay out here all night. Hopefully the hot tub has gotten warm enough, because I'm partial to wet sex right now."

"Does the well water have the same properties?" I wondered aloud.

"No. It's just the pond," Mom answered, as she and Megan parted and they got onto wobbly feet. Mom and I grabbed our bathing suits and we began to walk back to the cabin, as I began to feel the air getting colder. "The well actually had to be drilled deeper, to tap into a water table that's quite a bit below the pond. There doesn't seem to be any interaction between them at all. The pond isn't spring fed, for one thing. Rain fills it and there's a spillway at the west end to keep it at this level, unless there's a drought."

"Why not get the house's water from the pond itself?" I asked.

"Sediment. We all know that when you swim in it, you sometimes wind up with bits of rotted leaves and such on your skin. It's safe enough to drink small amounts, but it would clog up any pump and filter system Dad could install, so he chose to drill for a well, since the geological reports predicted there was water about 100 feet down. Even if he had known about the pond's special properties before making that decision, he said he still would have drilled, because it wouldn't be worth the headaches pumping from the pond would cause. Especially if filtration might remove that effect anyway."

"Whose source we still don't know," I said.

Mom sighed. "Dad and I needed to keep our incest a secret, so it didn't make sense to take the water to an outside lab. That hasn't changed now that it's the four of us keeping the same secret."

"You're right. Just like I can't reveal that I'm really his son."

Mom grimaced as Claire shouted, "What did you say?!?"

I turned to Mom and asked, "You told me they knew the secret."

"I told you they knew the pond's secret. I didn't tell them yours because I hadn't told you, yet, and they didn't have a need to know. I was going to tell you on this trip no matter what. It would then be up to you to decide whether to tell them, which you just did."

Mom then summarized the biological relationships I have with her and my sisters. We reached the cabin and went upstairs. I added more wood to the fireplace, as the inside temperature had only reached 63 because the log walls were still cold and the floor heating hadn't overcome that, although the floor itself was now comfortable to bare feet. We all got dressed and sat around the living room, with Claire climbing into my lap. My cock had finally gone soft, but threatened to revive with her squirming against it.

"Uncle Pete," Megan said. "I can't get used to the idea."

"Don't," Mom warned. "You can't ever call him that, outside of the four of us, so don't get into the habit. Even if the only incest that a DNA test could prove is his conception 22 years ago and that's too far back to be prosecutable, it would still impact my reputation and career and likely his as well. It needs to stay secret. Far better to keep thinking of him as your brother, so you don't slip."

"Yes, Mom," Megan and Claire responded.

Claire asked, "Did Dad know that Pete wasn't his biological son?"

"Yes. Grandma May knew, too. They weren't overjoyed by it, but kept the secret. I might as well tell you the whole story. Most of this cabin was built over the summer of '95 and was weather-tight by fall, with the fireplace and chimney in place. We swam in the pond that summer, but didn't feel anything special. The four of us then spent most of the fall and winter weekends coming up here to continue work on the interior. The first weekend after the ice melted, Mom challenged us all to swim in the pond for as long as we could take it. It was a day a lot like today, in fact. None of us had packed bathing suits, so we all skinny dipped. The water did its little trick and suddenly, Mom and Tom were fucking on the lawn between the shore and cabin. I turned to my Dad and said that I guessed it was a spouse swap and started going down on his cock. We then made love, with Mom and Tom barely batting an eye. However, Mom drew the line at having sex with me, though I would have been willing, and Tom and Dad didn't do anything sexual with each other, either. That's how I conclude that the pond doesn't create desire, it just overcomes resistance to what we already feel. Over the next few weekends, we felt the pond's power fade, even though we kept swapping partners."

I asked, "How did that turn into you and Grandpa coming up here alone?"

"The four of us agreed that Dad and I could continue being intimate, but only when we were here so there were no witnesses. Back home, we were to be faithful to our spouses. The next year, Dad and I came up here by ourselves to prep the cabin for spring and that's when Pete was conceived."

"On purpose?" Megan asked.

"No. I was on the pill, but I obviously ovulated anyway."

"Did you consider that the pond water might have neutralized the pill and let you ovulate?"

"Of course I considered it," Mom answered. "But I had absolutely no way to prove it and still keep the pond and incest secret. I did switch to a copper IUD after Pete was born and didn't get pregnant that next spring, although I would honestly have been okay if I had. Then I removed it to conceive the two of you that fall with your father, was pregnant the next spring and had my tubes tied after your delivery, so I no longer had to worry."

"And you got us on the copper IUD to protect us from the pond neutralizing our birth control, too?" Claire asked.

"When I recommended it for you, I hadn't made any decision about exposing the three of you to the pond's effects. The chance that the pond might neutralize the hormonal IUD gave the copper IUD the edge, is all. But, it's also possible I simply missed a dose of the pill and that's why I ovulated, instead of the pond doing anything. Then you two came here on your own and managed to not get pregnant by your grandfather. Whether that proves anything about the IUD staying effective, I don't know. It's not enough data. Because the two of you found out, Dad asked me while he was sick to bring Pete here to balance things and to pass this property to him in my own will, among a number of bequests."

Megan asked, "Can I jump back to the agreement you reached to limit your intimacy with Grandpa to here? Did that continue after Dad and Grandma died and Grandpa moved in with us?"

Mom said, "We continued avoiding each other at home because we didn't want to risk having the three of you catch us and because we were used to coming here being our special time together."

"What about the four of us, now? Are you expecting us to do the same thing? Not have sex with each other anywhere but here? Claire and I have managed to keep anyone from finding out about the two of us."

"So far. Look, the two of you are adults, so you're old enough to make that decision yourself. Just keep in mind that you're not the only ones at risk now, if you do get caught. That said, I am placing my house off limits to this and plan to only make love to the three of you here. Assuming Pete agrees, since I consider this to already be his property, even though the deed is held by a trust with my name on it for now. What you choose to do when you have your own homes is up to you. Understand?"

"Yes, Mom" Megan responded, followed by Claire and I agreeing.

"This place is mine?" I asked. "Why didn't Grandpa's will say so?"

"He didn't want to disclose that you were his son, to protect my reputation. So, he passed almost everything to me, with private instructions on how I'm supposed to pass those assets to the three of you, with you getting a bigger share as his son. I've already altered my will to do that, along with allocating more of what I inherited via Tom to your sisters to make it look more even, unless someone knows what the original sources of those assets are. Anyway, this property was put into a trust with me as primary beneficiary. You've been added as secondary, so you'll gain full legal control when I die, although it might be best tax-wise to keep it in the trust and add more beneficiaries. Once I'm dead, you can decide whether to claim your paternity. You're biologically a Conroy, not a Minoski."

"That still means revealing the family secrets. I think I'll stay Pete Minoski. It feels like I would be disrespecting Dad's--Tom's--role in my life to become Pete Conroy."

"That's part of why I love you, baby," Mom said, getting up to cross the room and kiss me, filling my mouth with her tongue. Claire started squirming even more in my lap as she watched us.

When Mom broke the kiss she said, "That's weird. Kissing you made my mouth tingle, like you or I had just drunk some of the pond water. That's never happened before."

"I felt it, too," I said. "Was it you or me or both of us causing it?"

"Let me see," Claire said, before she turned in my lap and began making out with me, too. She squealed in reaction as the tingles flared but kept kissing me for five minutes. My cock was solid steel by the time she finally stopped and said, "You make me so horny, big brother. Even more than the pond does, in fact. It's almost like you're producing the same effect as the pond, but without the water."

"That's unusual?" I asked.

"Yeah, it's never been how it works," Mom said. "Only the water produces that tingle, not the people exposed to it. Not after this much time out of the water. Why are you different, suddenly? I didn't feel this from you when we were on the dock."

"Why assume it's just me? Maybe we're all affected the same way?" I countered. Mom kissed Claire and then both of them kissed Megan, to confirm that they were only experiencing the tingling effect from kissing me.

Megan said, "I know this is going to sound really crazy, but is it possible that the waters changed Pete? Maybe not today, but when he was conceived? He would have been exposed as soon as he implanted your uterus, right, if not the sperm and egg before that? And now that he's been exposed to the waters again, they've activated something in him that the rest of us don't have?"

"You and your science fiction stories," I teased. Megan was not just a fan, but wanted to be a science fiction writer. "Am I a mutant in this scenario? Or am I going to transform into an alien tomorrow? Couldn't it just be that I'm the only male here?"

Mom said, "It never affected your dads this way, not once in 21 years, so I doubt it's gender-linked. I actually felt more turned on right before I kissed you. Could it be pheromones, too?"

"I'm exuding extra or they're more powerful or what? How do we figure it out without subjecting me to a barrage of medical tests?"

"That's not an option, clearly," Mom said. "We'll just have to make our own observations. It's not like it's a bad thing."

"It will probably just fade, anyway," I said, hoping it to be true, fearing that it wasn't.

~~~~~

We ate a light dinner, then checked the hot tub. It was up to a sufficient temperature, so Mom opened a bottle of white wine, deciding to let my sisters drink.

Within a minute of getting in, my sisters were snuggled on either side of me, their boobs rubbing my arms, taking turns stroking my hard cock while chatting with Mom about the latest happenings at school. Mom was only half listening, her eyes riveted to my shaft and glans whenever they appeared to her through the frothing water. I wasn't hearing a word.

I was suddenly glad that the water from the well didn't have the same properties as the pond. We didn't need the extra stimulation.

At the same time, all three women were acting like it did. More proof that my body was somehow exerting the same influence on them as the water did. The twist of it was that I wasn't feeling the same effects, except for that electric feeling in my mouth whenever my tongue met theirs. I felt satisfied from the afternoon's sex, although not worn out, while knowing that the three women weren't close to finished with me and the gulp of pond water was keeping me responsive as Claire had claimed. I had read somewhere that it was bad luck to turn down available pussy, though. Especially three delectable ones like my family's.

Giving in to what seemed inevitable, I put my hands between my sisters' thighs and started to explore their vulvas, comparing them. Claire had the more prominent inner lips, while Megan's outer lips were plumper and she maybe had the larger clit.

Megan was the first to take things beyond a light petting session, holding her breath to plunge her face into the water to take my cock into her mouth, rippling her tongue around and around. I closed my eyes and moaned, as that same electric feeling pulsed along my cock. If I was feeling that, what was Megan feeling?

"His cock tingles, too," she announced when she rose to take a breath. Claire's head took her place immediately after, as Mom approached on her knees and took the next turn.

Mom's mouth was wild, her tongue seemingly everywhere all at once. When she took me fully down her throat and started to lick my balls, I felt the same spark there, too. How did that make sense, if I was the one producing the effect? Something wasn't adding up, but I was hardly in a condition to be analytical about it.

She didn't surface for nearly three minutes, gasping for air when she did. I cautioned, "I don't want anyone dying for my cock, okay?" and pushed myself up onto the tub's rim so the three of them could continue sucking my cock above the water. Which they did with increasing gusto.Each of them got four more turns, my sisters trying to match Mom's skill at deep throating, while another sucked on my balls or kissed the other or sucked on each other's breasts. Occasionally, one of them would stand and I'd suck on their breasts. All of these actions brought the same effect, even when it was their tongues against my balls.

I was so close to cumming again that I didn't want to interrupt the action to bring it up for discussion, as I realized that not all of the tingles felt the same. Some were from my tongue in contact with them, others were simply reflections of pleasure, both mine and theirs. Was this how sex was going to be for me, from now on?

Finally, I couldn't hold back against the intensity any more and warned, "I'm almost there, Mom." She sucked extra hard and I popped, bursts of cum radiating like lightning bolts down my shaft, filling her mouth faster than she could swallow around my cock head. She withdrew, shaking in an apparent orgasm of her own. Megan's mouth was right there to take several more bursts and she likewise began to cum, with Claire finishing me off by hand, the last gobs of sperm hitting her petite breasts and running down her wet torso into the water.

I saw Claire reach a hand between her legs to stroke her pussy lips, but didn't realize that it was the hand that was still covered in my sperm until later.

Lightheaded, I lowered myself back into my seat, before asking, "Did... ummm... did my semen just trigger an orgasm in both of you?"

Megan nodded and said, "Amazing. I felt pleasure throughout my body any time I was sucking you or you were sucking my nipples. Then, I felt a jolt in my clit as soon as your cum hit my tongue and I just came and came." Mom still seemed woozy, having gotten the bigger dose, but nodded as well.

"How is that possible? For that matter, I felt that a tingling reaction whenever you licked my balls. How is that possible, if I'm the one producing the effects here? Is this just how pleasure feels to me now? I'm even thinking that my tongue and cock feel the pleasure they bring to you, too."

"How is any of this possible?" Claire countered, licking the last of my sperm and her own pussy juice from her fingers and experiencing a short shudder of her own. "We felt the same thing while licking your balls, yet you seemed to be the source. Call it magic if you want. Or maybe something extraterrestrial. We don't know why any of it works and may never know for sure. Unless it has negative effects, why worry about it?"

"Negative effects," I mused. "I think having every woman on campus suddenly swooning around me might just qualify, as much as some guys might fantasize about that. A case of too much of a good thing. Or worse, having everyone's inhibitions disappear because they're near me, even if I'm not the guy--or girl--they desire? We don't know if the pheromones I'm producing, if that's what this is, affect men. What if the person they want doesn't return those feelings? Do people start to disregard consent because they've turned super horny? Date rape is enough of a problem already, I don't want to be the source of it getting worse. I really hope this is a temporary effect of the pond that will fade by then. Something the four of us can experience together that doesn't affect the outside world and draw attention to us."

Mom said, "I, for one, hope it doesn't fade before you get a chance to fuck me again tonight. If your cock can do for my vagina what it just did to my mouth, you might just spoil me forever. Finish up your wine and we can head upstairs."

Damn. Even the wine tasted better in my mouth. What was this doing to my senses?

I finished my glass and got out of the tub, drying off with a towel. I stopped by the fireplace to add more wood, noting that the inside temp had risen to 67 at last. Then I climbed the stairs to Mom's room, only to find her sitting on her bed, tears on her cheeks, holding a two-sheet letter in her hands, written in cursive, while my sisters sat on either side of her, reading over her shoulders.

"From Grandpa?" I asked. Claire nodded yes.

Mom finished the letter, wiped her tears and handed it to me. "I remember Dad being the last one upstairs when we closed the house up last fall. He must have left it here then for us to find now. He's known the real secret of the pond since before you were born but never said anything because he didn't want to lose his chance to be with me every year. Apparently, some kind of silicon-based life form survived a crash landing here about 100 years ago and exited its lifepod into the water and has been capturing nutrients from the pond bottom. It resembles a large rock, but isn't. You could swim right by it and think it's just a boulder covered in pond gunk. The species has telekinesis when they're young, but that converts to telepathy when they're older and able to mate. With only a little of their telekinesis left, they are dependent on the younger members of the species for mobility. But, without a mate here, it can't produce children who could move it out of the pond. However, it still instinctively prepares for its mating cycle when the water is at the right temperature, just as the surface melts. We're being affected by what are in essence its own pheromones before they evaporate, along with a telepathic boost from the creature that is enabled by them."

"How did Grandpa figure this out?"

"Apparently, it communicated to Dad in his dreams, but only with him. Nobody else. Don't be surprised if you have a strange dream of your own tonight. Also, the water gets neutralized by going out of telepathic range. These special abilities you're displaying might likewise be neutralized when we leave here. Maybe. Dad didn't say anything about being affected without contact with the water, as you've experienced tonight. I certainly was never affected by him as strongly as I've been affected by you tonight."

"What does it get out of boosting our arousal, though?" I asked.

Claire blushed, while Mom chuckled and said, "It has its equivalent of an orgasm when we do, empathically. It's still trying to mate. But, as it hibernates once it gets warmer, the arousal effect is most apparent when the water is in the narrow band between freezing and too warm for it. Once it stops secreting these pheromones, they evaporate. And it stops boosting the effects of the ones that are left."

"But, if I were to come here and cut a hole in the ice, the water would have the same effect during the winter?"

"No, it starts its mating cycle as the water starts to melt and it ends when it enters hibernation for our summer, about three weeks later. It's in the letter. Reading it can wait, because I'm feeling really horny now that I know that you're going to be okay. I still need to get fucked until I can't take any more."

"Me too," echoed my sisters.

"With all the pleasure I can bring to the task." My cock was already hard in anticipation.

"Me first?" Claire asked. "I really want to know what it feels like to have you shoot off inside me, see if it's going to make me instantly cum like it did Mom and Meg."

She climbed off the bed, then leaned over it with her legs spread and her pussy peeking out at me from between her slender thighs. Mom rotated on the bed to bring her pussy in front of Claire's face and Megan moved to squat over Mom's head, sighing when Mom's tongue began to move in her.

I moved behind Claire and stroked my hard cock up and down her slit two times, feeling it bump into her aroused clit, then lined myself up with her opening and slowly pushed inside. That electric feeling returned instantly and made Claire jolt.

"Holy shit," she muttered into Mom's pussy, muffled by her tongue flitting around Mom's labia.

I stroked steadily into her, trying not to orgasm too quickly from the added sensation I was experiencing. Once again, I wanted my partner to come first. Guessing at what would happen, I stuck two fingers into my mouth to wet them and brought them around Claire's hip to stroke around her clit. I felt as if a spark shot from my fingers to her nub and she immediately started to shake.

"Ohhhh, fuck, fuck, fuuucccckkk!" she cried out, thrusting her whole body back at me to take me as deeply into her as I could go. The energy pulsing through our bodies only intensified and I barely stopped myself from having an orgasm far too soon. I kept pumping in and out, as Claire's orgasm seemed to roll on and on.

She came twice more and on the last, I finally couldn't control my own reaction and launched several volleys of semen deep into my sister's squeezing tunnel. "Yes, yes, YESSSS!" she cried, as she felt it splash against her cervix and another orgasm ripped through her. My whole body spasmed in pumping the last of it into her. It was the most intense orgasm I'd ever felt.

Claire disengaged from me and quickly dropped to her knees to take my cock into her mouth once more, sucking the remaining sperm from me like it was manna from heaven. She continued writhing in a series of small orgasms as a result of it. When there was apparently no more jizz to suck from me, she stood and kissed me, saying, "Thanks, Pete. Fuck Mom now."

I looked down and Mom had her legs spread, her fingers spreading her enflamed labia and rubbing lightly across her clit while she continued licking Megan's. I made my way onto the bed, kneeling before her and lifting her legs onto my arms so I could tilt her pelvis enough to slide deep into her wetness. Another zap of pleasure ran through my body.

As I began thrusting slowly into Mom, Megan leaned towards me and we kissed, softly at first but with increasing fervor as energy seemed to flow in an alternating circle between the three of us, sometimes feeling like it passed from Meg to me and onward to Mom, other times the opposite direction. Gradually, I picked up my pace and the waves of pleasure sped up to match.

Claire appeared on the bed again, to suck at Mom's breast and diddle Megan's clit while Mom sucked on Megan's labia. I felt the energy flow shift to include Claire's contact and almost felt like I was empathically experiencing joy from all three of my partners as we all reached a crescendo at the same moment, as I came for the second time in ten minutes. Even Claire was shaking in a small orgasm, just from the energy flowing indirectly into her. I expected to shoot only a small load, but instead I gushed as much cum as ever into my Mom.

When my orgasm ended but I was still rock hard, I rolled onto my back next to Mom and coaxed Megan to straddle me. I wasn't done and I sensed she wasn't, either.

Claire moved into a 69 with Mom, before she even had a chance to stop cumming, and proceeded to start licking up the mess of sperm I'd left inside. She joined Mom in another orgasm, apparently just from tasting my leftover essence. The phrase "cum slut" passed through my mind. But I suppose if I were cumming just from a taste, I would be one, too.

Megan took our fucking slowly, clearly trying to make it last longer, where things had been happening quickly so far. I looked up into her eyes, seeing her love beamed back at me. I held her breasts in my hands as she rose and fell, but wasn't trying to do much to stimulate her nipples, letting our arousal build slowly. But even that contact made energy flow into my hands, almost ticklish at this point. If I was feeling that, what was Megan feeling?

"I love you, Pete!" she cried out, just before I felt her body tense over me in another orgasm that drove more sensation straight through my cock to my balls, which tightened in preparation for another ejaculation.

"Love you back," I groaned, trying desperately to stave off this orgasm, wanting this round at least to last a little longer. I managed to last another ten minutes, with Megan coming twice more, before I exploded in a shuddering jolt, the semen and energy both pulsing out of me for a minute or more. Megan collapsed onto my chest, still shaking from the effects my sperm was apparently having inside her.

Everywhere our skin touched tingled, fueling our orgasms to continue. Finally, they ended and the contact effect faded. I kissed Meg one more time, not feeling that electricity between our tongues this time. She broke the kiss and asked, "Did it wear off?"

I needed fifteen seconds to think again, during which I realized I was also going soft. I finally answered, "Maybe it did. Maybe there's a recovery period, like with erections. Even knowing about the alien, I don't think we understand everything that's going on and maybe we never will."

Mom and Claire had already stopped making love to each other and were clearly exhausted. We agreed to sleep, all of us in the same bed, with me between Megan and Mom, with Claire on Mom's other side.

~~~~~

As Mom predicted, the alien creature in the pond spoke to me in my dreams. Its name was a varied series of clicks without vowels, that my memory can't seem to retain and couldn't approximate in words even if I did.

Name ------. Please to acquaint.

Ummm... Hi. I have a lot of questions.

Aware. Primary how affect mates without water? Meg-gan guess partly correct. Not alter DNA, but DNA make mind easy reach, boost pheromones all times. Sense energy flow. Share sensation.

So, I'm going to have women falling all over me, like I worried?

Only women already attract. Nudge only. Strong here.

Okay, next question. Did you neutralize my mother's birth control pills, to let me be born?

Water allow Barbara egg release. Also correct copper protect. But mates Meg-gan and Claire not wear. Have child. Barbara want child, help egg meet sperm.

Wait. You're telling me all three of them are pregnant? That you defeated a frigging tubal ligation?

Three mates, four healthy children by cold time. Claire two, cells split. Not want, Peter?

Ummm... I want children, someday, with a woman I'm married to. Not with my mom and sisters, when I could go to jail for being the father and there could be genetic problems. I don't know what your world is like, but here incestuous births are considered genetically unsafe and there are legal punishments. Severe ones. What are they thinking?

Love you. Want child by you. Healthy children. Have plan. Ask.

~~~~~

That's when I woke with a start, waking my three bedmates. It was 3 AM. I didn't know how to start the conversation I needed to have. I moved away from them to sit at the foot of the bed, so I could make eye contact with all three, while they sat up against the headboard. Mom turned on the bedside lamp.

"You spoke with it?" Mom asked.

"Briefly. It confirmed that my DNA makes me more receptive to its power and that I have boosted pheromones even when I'm not here. It denied altering my DNA, though. But, what woke me was ummm... its news that all three of you are pregnant, that you all want my children and that you have some kind of plan? It said that all of the children will be healthy. How that happens without manipulating DNA, I don't know. Still, this plan had better be fucking good."

Surprised looks were exchanged between my mom and my sisters, making clear that they weren't in on some concerted plot against me. At least, not the same one. Yay me.

Mom answered first. "I didn't reverse my tubal ligation, so I didn't expect I could get pregnant. But I thought that with my dad, too. I did have some dreams about having your baby, even thoughts about it while we've been here today. Maybe that's what the pond creature identified as my wanting your baby. I'm not in the least bit upset at the news, though. It feels right to my heart."

"That could be the creature's telepathic influence," I pointed out.

"Maybe. There's not much I can do, if it is. As for a plan, my OB/GYN is the only other person who knows who your true father is and she has kept the secret this whole time. When I decided to have my tubes tied, your dad had some of his sperm frozen in case I ever wanted to do IVF later on. That's still in cryo-storage. So, if I need her to falsify entries in my medical file saying I did do IVF, she would. I'll make an appointment when we get home. That should cover me, so long as I avoid DNA tests and this baby is just as healthy as you are. I don't know what the girls have in mind. I agree it better be good."

Megan smirked at me briefly, before she realized I wasn't going to let her be glib about this. She changed her expression and explained, "Claire and I met twin brothers at school, Matt and Mark, who have their own apartment off-campus. We discovered that they're also lovers, but they date women, as cover more for their incest than their homosexuality. They figure that if people think they're straight, they won't be suspected of incest. They aren't bisexual, so we haven't had sex with them, although they're both hot. Double dating with them has kind of been a beard situation, but in both directions to hide our mutual incest. We go out, then go back to their apartment, they have sex together while Claire and I make love separately. This way, we don't risk getting caught in the dorms and their neighbors hear both male and female voices. We just have to be careful to not cry out the wrong name. They might be willing to make it a more permanent thing after college, to get married and live together as one family in the same house. But, they've already agreed to let us put their names on our children's birth certificates, whether we marry or not."

I asked, "Jeezus. Did you already tell them I was going to be the biological father in this scenario? Did they also know you intended to trick me into impregnating you?"

Megan said, "You're mad," like it was a surprise to her.

I erupted, "Seriously, sis? How the fuck did you think I was going to react? Did you think of my feelings at all? Mom at least thought she was protected from pregnancy, not knowing that there was an alien in the pond that could get her egg past her tubal ligation to reach my sperm and be fertilized. Perhaps even pick which sperm to let through to fertilize it, for all I know. That might explain why I'm healthy and these kids will be, too. But, the two of you intentionally had your IUDs taken out well before you came up here and then let me think they were still in place while we had sex. Even when we discussed the pond's affect on hormonal birth control and Mom's belief that you were still protected by your copper IUDs, which you would have been, you didn't say anything about taking them out."

Claire shyly admitted, "You... hadn't cum in me yet."

"Great justification!" I shouted back at her, seeing her cringe. "Do you two hear yourself? A lie by omission is still a lie and this one is huge. I didn't agree to becoming a father for any of you and now I have not one but four children on the way that I can't possibly claim as mine without going to jail? Not how I wanted to start a family."

"Four?" Megan asked.

"Oh, that's right," I said. "Claire, you're having twins. Congrats. The alien told me that the cells split, so that means they're identical instead of fraternal. The two of you still haven't answered me. Why did you do this? If you had asked, I might actually have said yes, if I could be sure the babies would be genetically healthy, but you never gave me the chance to choose."

Claire meekly answered, "You weren't supposed to know. Everyone was supposed to think that Matt and Mark are the fathers. We figured that if you did find out, it would be easier to ask forgiveness than permission. I'm sorry we lied." Megan nodded her agreement.

Mom said, "Keeping this a secret from him doesn't make it better, girls."

Trying to calm down, I ran my hands through my hair, before asking, "When did you start thinking about having my children? It wouldn't happen to be after you were exposed to the pond effect last year, would it?"

Mom asked, "You think the alien planted the idea in their heads?"

I answered, "I think it's possible we're all being mentally manipulated to serve its purposes in some way, yes. We already know it's capable of erasing our inhibitions. I'm not clear whether that's only something in the water or if its telepathic abilities are involved, since it doesn't happen when it's asleep or when the water is taken away from here. But if it is telepathically removing our taboos, why would I think it can't also alter or plant thoughts? All these years, Mom, you've based your belief that the pond doesn't create desire on the fact that nothing same-sex happened. But, what if those were simply the pairings the alien wanted, with Dad and Grandma only coupling to spur you and Grandpa to have sex? They didn't pursue it again afterward, but you and Grandpa did, year after year, but only here. Could the taboo be part of what it likes and it didn't need you to get together away from here?"

Mom said, "Breaking the taboo helps get it off, you're saying? I suppose that's possible. There are plenty of humans who get off on incest as a fantasy because of its emotional context. Why not an empathic alien?"

Turning back to my sisters, I asked, "So, I'll ask you two again. Was that when you started to think about having my children or not? And did anything convince you that it would be safe?"

Claire responded, "It was before last spring, at least for me. Wishing you somehow weren't my brother so I could have your babies was my birthday wish when I turned 18, right here at the camp, but I'd already been thinking about it. Rather than pursue you, I focused on finding a guy just like you. I thought then and now that you're perfect for me, Pete, except for being my brother. I didn't think I had a chance to have sex with you until we came here last year and we discovered what the pond could do."

"Which you thought took away my ability to turn you down," I grumbled. "What about you, Meg?"

Megan answered, "I felt really attracted to you over the summer we turned 18, but I wasn't thinking about having your kids until Claire brought it up after we'd been with Grandpa and we agreed to do it together. The only obstacle then was getting you up here in March. Instead, Mom asked you and we had to join in. Not because we thought the pond would make you say yes, just that it made it more likely."

"So, you both had some incestuous desire toward me before the pond erased the taboo and Claire was already thinking about having my kids. What about toward each other?"

Claire said, "That desire's been there our whole lives, I think, but we didn't act on it."

"Anyway, what caused you to come up here on your own, last year?"

"You're thinking the alien coaxed us here long distance?" Megan asked.

"Don't answer my questions with questions, Meg," I snapped. "This is too important. Why did you come here?"

"I wanted to see what the camp was like this time of year, since we always waited until Memorial Day to visit and I never understood why. I dared Claire to swim in the pond with me before we got here, too. We weren't expecting Grandpa to be around, since we knew he and Mom had come here the weekend before to open the camp. Before you suggest it, neither Grandpa nor Mom talked with us in between them being here and our deciding to come, so the alien didn't influence them to suggest it."

I said, "I'm more concerned about the alien possibly planting the idea in your head the summer before, when you turned 18. I know Grandpa says it hibernates during our summer, but the water does still have a mild effect. Maybe it's still partially conscious or doesn't sleep a full 24 hours. We held your 18th birthday party here, remember? The water could still have influenced Claire's birthday wish and how you felt toward me that summer. Or maybe it just read Claire's wish for my child and needed her to conceive here so it could prevent any genetic problems for us? While getting you to believe that doing so would be safe, despite all the warnings we get about incest causing birth defects."

Claire said, "That's sounding a little contrived and paranoid, Pete. The idea of coming here last year was Meg's, not something I'd been thinking about since the previous year. And if it was going to plant a post-hypnotic suggestion in both our heads, why didn't it also plant one in yours so we'd be here at the same time? Also, I don't see anything it has done that's hurt us. If it's ensuring the health of my baby--babies--I'm grateful."

I mulled that over before saying, "It did make it sound like it was reacting to what the three of you wanted, rather than driving your choices. So, maybe I'm being suspicious for nothing. Although I'll point out that if it had gotten us to rendezvous last year, you would have still had your IUDs in and you wouldn't have gotten pregnant. What you're saying, though, is that the idea to have my babies was your own, despite the expected risks, the choices to come to visit the pond last March and again now were also yours and you're 100% responsible for tricking me into getting you both pregnant today. Is that about it?"

"Yeah. Were you trying to come up with reasons why we weren't responsible? To make it easier to forgive us?"

"No, I wasn't trying to forgive you. That's going to take some time, to be honest. I was trying to figure out if we're in danger of being mentally controlled," I said. "I have a hard time believing that the only thing the alien wants from us is to provide it a few orgasms each spring. Did it actually alter my DNA, instead of just preventing problems? What more might it be doing to this new generation of children right now?"

Mom asked, "Pete, if I were stranded alone on a planet, unable to move, those orgasms and the mental contact associated with them might be awfully valuable. Without us here, it would be entirely alone and was alone for decades before Dad bought this land. I'm with Claire. I see no sign that its intentions are harmful. I don't regret anything that's ever happened here. Certainly not conceiving you and I won't regret this new child, either. If you really think it's pursuing some additional agenda, ask it if it appears in your dreams again. Otherwise, we're just going in circles speculating. Let's get back to sleep. Girls, tomorrow we can talk about how you plan to complete your college educations with three babies to raise."

"Yes, Mom," they both said.

~~~~~

Mom and my sisters fell back asleep quickly, but it took me about 20 minutes that I spent listening for the alien's voice in my head. When I did fall into slumber, it didn't visit me again that I remember.

The sensation that woke me in the morning was one tongue rimming my ear while another circled one of my nipples, just before a mouth engulfed my morning wood. The sparkling sensations from the day before were indeed gone, but what remained was more than enough to make my toes curl. I kept my eyes closed for nearly another minute, trying to see if I could guess who was who, but failed totally. There were too many sensations to separate and not enough experience being with them to discern differences in their actions. I surprised myself by wishing I had many more opportunities to be with all of them so I could learn.

I also no longer felt angry with my sisters. I hoped it wasn't because the alien had altered my emotions in the night. I prefer to think it was my love for them winning out.

Don't mistake me. I hadn't forgiven them yet. I just no longer felt the blazing hot anger I had.

When I opened my eyes, I discovered that it was Mom kissing around my ear and neck, Claire kissing from one nipple to the other and Megan sucking my cock as deep into her mouth as she could without gagging.

An involuntary grunt alerted the three of them that I was awake, before I could mutter, "Morning."

"Morning, lover," Mom whispered into my ear, before licking it some more.

Claire moved down my torso and straddled my legs to fuck me cowgirl style again, making eye contact with me but not saying a word.

Megan crossed behind Claire and moved into a 69 position with Mom. Her pussy was an enticing distance from my face, as I watched Mom's tongue slide between her wet labia.

I returned my eyes to Claire, as her smaller boobs began to jiggle on her chest in time with her rise and fall on my cock. I moved my hands to grasp both small mounds, the two hard nipples pressing into my palms at first. As I squeezed her breasts, I moved my hands so the nipples slid between the middle and ring fingers of each hand, which let me squeeze them separately.

"Oh, fuck, Pete, that's good," she finally said, breaking her silence.

"I shouldn't... love fucking my... family so much," I said, between gasps. "But I do. I love you all. I love showing... it this way. I don't... want to stop."

"Me neither," she gasped, with the kind of smirk on her face that said she was happy I wasn't angry with her.

Mom was moaning more loudly into Megan's pussy and I took another look over to the two of them. Mom noticed and winked at me, while she was thrusting two fingers inside Megan and rapidly circling her clit with her tongue.

I said, "The tingle is gone, this morning."

Pausing atop me, Claire said, "We noticed already. Can you still make me come without it?"

"I think I can manage."

Our love making was slow only in comparison to the night before, working Claire up to orgasm three separate times, before my cock finally blew a load deep into her already pregnant body. I estimated that my Mom and sister had come beside us as many times each. My cock, no longer boosted by the pond, went soft rapidly after that. We cuddled together as Mom and Megan did the same.

"Bacon, eggs and hash browns sound good for everyone?" I asked, when everyone's breath had gotten back to normal. "I sure know I've worked up an appetite in the last 24 hours."

Mom asked Megan, "Can you and Claire strip this bed and get the sheets into the washer, while Pete and I cook breakfast?"

"Sure, Mom."

While Claire and Megan were down in the basement and Mom and I were cooking breakfast, she asked, "How are you feeling about the baby news, honey? Honest answer."

"Nervous acceptance, I guess," I answered. "I can't undo it. Rather, I won't ask any of you to abort. I'll eventually forgive them for tricking me. I love them too much for that and the anger I felt at first has already faded. What bothers me the most right now is that I will have to keep it a secret. I'll be a dad times four, but I won't be able to tell anyone. I'll be Uncle Pete to Claire and Megan's kids and a big brother to yours. And that's it."

"Your father--Grandpa--felt the same way."

"Then, why didn't he tell me, once I was old enough to understand?" I asked. "I loved him like a dad. Why couldn't he let me call him that, at least once?"

Mom answered, "A mix of being afraid that you'd reject him if he did tell you and an acceptance in his heart that the label really didn't matter. That the love did. And he loved you like a son, even if he never called you that. So will you, in time."

"Hmmm. And you decided to wait until this week to tell me yourself. Figuring that it would go down easier with a serving of pond water to erase the reaction the incest taboo might have caused?"

"In part. I also wasn't sure you'd believe the whole story without a demonstration. Only to find out that the story is even weirder."

"If we know the full story, even now," I said.

Mom asked, "You're still thinking the alien has other motives?"

"Something about what we know just doesn't feel right, like there must be something more."

We heard my sisters coming back up the stairs, so set aside that conversation and finished plating the food for breakfast.

Mom then lectured the girls on staying in school and they promised they would, with a plan to find a larger apartment to share with Matt and Mark. Not quite that short a conversation, but I don't want to regale you with every word.

After breakfast, I followed Grandpa's instructions for doing a diagnostic test on the solar power system, which didn't show any problems, followed by a visual inspection of the panels on the roof and on the hill behind the house. Mom and my sisters worked on dusting and other cleaning inside, as the day was cooler. After a lunch of sandwiches, Megan and Claire departed to return to their school. They both kissed me and apologized once more for tricking me.

Dark clouds were beginning to roll in as we watched them drive away, and I asked Mom, "Does the forecast call for rain, this week? We still have yard work that needs to be done."

Mom answered, "You get the mower out now and I'll go check the forecast."

I had just finished mowing the grass between the cabin and pond and shut off the engine, when Mom came out to the deck and said, "The forecast calls for rain starting tonight and continuing to Thursday."

"So much for the other outdoor spring cleaning," I said. "It will probably be too wet to do much after the rain stops, too."

"Don't worry about it. Rain gives us more time to cuddle before the fire, watch movies, fuck," she responded with a big grin on her face. "That was always the main purpose of coming here with Dad, anyway, unless our inspections uncovered something that needed to be repaired without waiting for parts. If I'm placing home as off-limits to sex, I want more opportunities to fuck you before we leave, anyway."

"Do you want me to turbo-charge in the pond, so we can repeat what happened last night, but just the two of us?"

"Not tonight, but maybe in a few days?

I put the mower away and went into the house. We started another fire and spent the rest of the day and night in the living room, alternating between movies and sex, finally climbing the stairs to Mom's bed, around 10.

The slower pace and softer lovemaking was a nice change of pace, compared to how Saturday had gone. Cuddling and kissing in between rounds was what I appreciated the most. Having an unending erection isn't always the best thing. We alternated a bunch of positions for intercourse, but focused on keeping each other in eye contact.

Rain continued on Monday and we spent the whole day much the same way.

~~~~~

Tuesday morning, we swam in the pond--now totally free of ice--for a long time, while rain fell around us. The sensory effects were perhaps even stronger, when we started to make love inside before the fire. Everything was intense, but the water kept us invigorated longer than I expected. I think I actually came 10 times over the course of the day. I have no idea what Mom's total was, since some ran together.

This was pure fucking, using almost every position we hadn't tried over the two previous days. Perhaps my favorite of the day was leaning Mom over the couch and fucking her from behind, while I held her around the breasts with both hands. Every stroke into her landed with a pop of my groin against her buttocks that felt like a thunderclap, while I pulled her back into me. Her buttocks shook with every impact, causing grunts and moans. She had four shuddering orgasms, where she almost lost her ability to stand, before I had another of those lightning bolt ejaculations, my semen leaping out of my cock into her along bursts of pleasure we both felt. I was still hard after it, so I kept right on fucking her to two more orgasms before I came again.

"God, the cum is running down my legs," Mom said, pulling away from me and turning around. "You're no cleaner. We need a shower before dinner, or we'll mess up the chair cushions."

We used the shower in the downstairs bathroom. But, when I tried to wash Mom's pussy clean, my fingers wound up stimulating her and she had another orgasm. "Damn, I'm not going to get clean this way," she laughed, once her moans stopped. "Let me finish and you wash yourself, you orgasm inducer."

The turbo charge faded around midnight and we fell asleep in each other's arms on the living room floor.

~~~~~

Eating breakfast on Wednesday morning while it poured outside again, Mom shocked me when she asked, "Do you think we could duplicate what the girls are doing? Find another incestuous couple to pair with and hide our incest behind two legal marriages? A dad and daughter? Bonus if we fall in love with them, so we can be a true foursome?"

I looked her in the eyes and said, "First, I'm not sure how we would go about finding them. It's not like there's some dating site or registry set up for it. Second, I thought you wanted to limit our sexual relationship to here and keep home off limits?"

"I can change my mind, can't I? I don't know that I'll be able to resist you, after this week. I love you, Pete, not just as my son or as my brother. Full-on romantic love. The kind that makes me wonder if we've loved each other in past lives and just wound up relatives in this one. Blame the alien if you want, I don't care. I want you as my mate, even if you can't be my husband. And I want us to raise our child together."

"And I love you just as much... Barbara." I said. "Ohh, that doesn't feel right in my mouth."

Mom chuckled and said, "You can't afford to use my real name, any more than your sisters can call you Uncle Pete. Stick to Mom."

"You're right. At the same time, I have to continue looking like I have a social life, while we look for a couple we may never find."

"Unless we use the pond to unlock their incest taboo, too," she said and I choked on my coffee.

When I stopped sputtering, I asked, "Are you serious? How is that ethically different from using a date rape drug?"

Mom answered, "Do you really think I would do that? I stand by what I've said all along, that the pond--or the alien--doesn't create desire where it didn't already exist. It just removes the taboo, allowing you to say yes when your heart wants to say yes but society would tell you to say no. I wouldn't bring another couple here unless I was convinced they were attracted to each other. Do you remember our first time, down on the dock? I asked you if you wanted to have sex. Do you remember your answer?"

"Yes, more than anything."

"Did the alien put those words in your mouth? Take away your ability to say 'no'? Make you feel differently about me than before? Or did it simply unlock the intellectual opposition to it, the taboo society hits us with? Think about how you felt."

I examined my memories for almost a minute before answering, "Besides feeling extremely aroused physically, the only thing that felt different emotionally was surprise that the taboo was gone. What I felt about you, about your sexy body, was the same. Amplified, maybe, but the same. The taboo was what kept me from acting on that attraction."

Mom nodded, saying, "Exactly. You already desired me, but resisted that because of what society told you. I certainly never lectured you about being too affectionate with your sisters or anything like that. If something had happened sexually between the three of you before this weekend, I would only have cautioned you about keeping it a secret. And then maybe joined in with you."

"The thing is, Mom, you still used lies of omission to get me into the pond, just like Claire and Megan did in not warning me that they stopped using contraception. Why is that okay?"

"I was seeking your consent, where it mattered. They weren't, not regarding the pregnancies. That's the difference. I believe that I could have seduced you without coming to the pond, given enough time. I almost tried last summer, once you were the last member of the family who hadn't committed incest, but I felt it needed to be one-on-one time between the two of us and this Spring Break was my first opportunity for us to be alone. Had we arrived to find the pond still covered by ice so we couldn't put the docks in, I was going to try and get you into my bed anyway. The pond served as a shortcut, only. But it was never about taking your consent away."
