SISTER IN LAW BACKSEAT

t had been a great concert. Festival really. Five rock bands that my wife and I had loved when we were younger had reunited and were on tour playing stadiums, areas and, in this case a large grassy field about an hour from our home in Toronto.

When we saw the tickets go up we had snapped them up, picking up one for an old friend of ours and, surprisingly one for my wife's much younger half sister, Jenny.

I say surprisingly because while I am 40 and my wife, Kristen, is 39, her sister is from my father in law's second marriage and she is only 19 years old, not someone you would expect to enjoy a show of middle aged rockers and fans re-living their youth.

Not that I minded. My wife's sister is fun and funny and, honestly, pretty enjoyable to look at. She's 5'4 with thick curly brown hair, wide set eyes, a cute button nose with freckles dancing across the bridge and over her cheeks. She always seems to be smiling. Her small frame carries a full chest, (I would guess 36D? I dunno. I'm terrible at guessing these things) a relatively small waist and full hips and ass. I have to admit that I may have found my eyes inappropriately lingering on her body from time to time at family events.

This isn't to say that I had done more than that: look. I was happily married to a woman I find beautiful. Kristen has aged wonderfully. She has a full figure as well (my preference) and the slight crows feet around her eyes and the odd grey hair (which she promptly plucks out) are the only indications of her age. She gets asked for ID when purchasing liquor and most people assume she is in her late twenties not late thirties.

I suppose since I've been describing these women I should tell you about myself. My name is Mark. I've been told I'm handsome. Most people are surprised by my age as well, though I no longer get the guess of 25! I'm 5'11, and keep in decent shape. For a while I was building up a bit of a belly and love handles, getting a real dad bod, the result of long hours spent at work behind a desk, but I was uncomfortable with that so started running long distance. My blond hair is thinning, but I'm not bald. I have a full beard that is beginning to get steaks or Grey (which I kind of like).

I suppose the choice not to have children my wife and I made has contributed to our relatively youthful appearance. My friends who had families do not look like us. They look like parents.

Anyway, our friend, Bill, had volunteered to drive since he quit drinking five years ago and we were in his car on the way home. Kristen was in the passenger seat. She suffered from pretty bad road sickness sometimes and could not handle sitting in the back. She had the AC on high and was trying to fall asleep to combat this. I was in the back seat with Jenny.

"Can you turn down the AC?" Jenny asked rubbing her arms. It was a warm summer night, though now that the sun was down it had gotten much cooler, and she had worn a fun but not warm outfit to the concert.

I glanced over at her. Her top was a blue textured tube top that rolled over her full breasts, hugging under them and stopping just above her belly button. Her skirt was loose and came halfway down her thighs. I must admit that I had enjoyed watching her dance to the music earlier with my wife.

Looking at her now I noticed that the cold air in the car had made her nipples hard and they were tenting out the material. I tried to be discrete but marveled at how high her breasts still stood. Ah, the wonders of youth!

"Sorry," Kristen called back. "I need the cold air to keep my nausea down! It sucks I know but I can't help it."

"I have a blanket back there," Bill called back.

Jenny looked at the blanket that was on the seat between us and shrugged.

"Ok. Maybe later," she said off handedly.

Kristen seemed to fall asleep then and Bill, saying that he needed something to stay awake turned up the radio. Both Jenny and I were looking at our phones.

I was scrolling through Instagram, checking out the photos of friends, artists I like and funny memes. As I was flicking my thumb across the screen I heard Jenny say quietly, "Oh, she's cute."

I glanced up at her and saw that she had been watching my screen not hers. I scrolled back down and saw what she had referred to: a photo of a tattoo artist I followed, in this case wearing a cute top that showed off a pretty impressive set of tits.

"Does Kristen know you follow hot chicks?" Jenny teased.

"Hardly," I scoffed. "I think you'll find this pretty tame." It was true. I didn't really use Instagram to look at girls.

"Lame," she said smiling. Suddenly she plucked my phone out of my hand. "Here, let me show you something...my account...it's private so I'll have to approve your follow..." she handed my phone back and picked up hers, presumably approving my follow.

I was curious so I took a look. My eyes widened as I began to scroll through the feed of someone with the username @jennyhazfun88. All the pictures were of the same girl, in various sexy poses wearing various sexy outfits. And they were, of course, all of my sister in law.

"Uh," I stammered, unsure of what to say, what she wanted from me, why she showed me this. "It's..you?"

"Yeah" she said quietly. "It's like a fun, I dunno, project? What do you think?"

I should have closed the app. I should have said something non-committal, something appropriate. I should have. But I continued to scroll. Here was a picture of her, camera angled up at her, in a very small red bikini. Her pale skin like porcelain, the undersides of her breasts round and inviting. Another of her in the bath with bubbles covering her lower half and an arm draped across her chest, hiding her nipples but nothing else. The next one was of her laying on her back on a bed, wearing a thin babydoll negligee. Beside her, laid out in a fan formation were four dildos and vibrators of varying sizes. The caption read: busy night ahead of me!!

Now I am only human. I cannot help the fact that I am a man and I react to...certain stimuli. My cock, which had been contentedly resting flaccid between my legs, suddenly, and excitedly began to wake. I was wearing light, loose shorts (perfect for a hot summer day at a festival) and as I began to react, my cock filled, thickened and lengthened down there leg of the shorts lifting the fabric slightly. I glanced down and, while I could see clearly, I hoped that in the dark of the car Jenny wouldn't notice.

I coughed nervously and finally looked up, away from my phone and at her. She had shifted so that she was leaned back against the door behind her. She was watching me carefully, green eyes focused on my ice blue ones. I couldn't help but to scan her body, one o had seen so clearly in those photos.

I had noticed her nipples were hard earlier from the cold air. If I wasn't mistaken there were harder now. Making more of an impression against the fabric of her tube top. My eyes slid down further and saw that her skirt, either because of the way she had shifted or by design, had moved higher, revealing most of her smooth thighs. Any higher, I realized I would see her underwear.

I shook my head and forced my eyes back to meet hers.

"Um..."I stammered, unsure about anything at this point, "what...what the hell, Jenny."

She smirked and put on a false pout.

"What," she teased, "you don't like the photos?"

"Um...they are very nice...but why did you show me them?"

"Only nice," she asked, ignoring my question, pouting some more, though I could see her eyes dancing with mirth, "that's too bad. I thought some of them were pretty good."

"It's not...they are...yeah. They are good for what they are but...what the hell? Does Kristen know you have this account?" There. Remind her about my wife. Her sister. That should bring this back down to a more appropriate level.

"Kristen?" She chuckled. "Nope. No one who knows me knows that I do this. Just you. I guess it's our secret."

I didn't like the sound of that. I had been married for 12 years at that point and knew that secrets were terrible and almost never worth it.

"Well," I said. "Very nice and all but let's leave this at that." I was using a firm voice, the one I use with my staff when they are in need of some gentle guidance.

"Oh," she said, "but you haven't seen them all! Here, let me show you."

She was quick. Quicker than I was able to process what was going on. She unclipped her seatbelt and slid the very short distance between us, scooping up the blanket and putting it on her lap.

"I guess I do need the blanket after all," she said loudly to the car. I winced. Bill, who was nodding along to the music glanced into the rear view and gave a thumbs up. Kristen, to my horror stirred and glanced over her shoulder.

"Ya, sorry," she said sleepily. "Jenny, share with Mark. He won't admit he needs it but will wind up whining after we get home." Then she closed her eyes again and seemed to drift to sleep.

"Good idea," Jenny said and flicked the blanket across our laps.

She was pressed against me, her bare thigh (had her skirt ridden up any higher? I couldn't tell because of the blanket) pressed against my leg, skin touching skin below the fabric of my shorts. She was half turned so that her breast was pressed against my upper arm.

If my cock had been half hard before, it was now, almost painfully at full attention. I could smell her. A mix of a light perfume, the vaguely floral scent of her hair products, and below that the almost sweet musk of someone who had been out in the sun all day dancing and having fun.

"Let's look together," she said quietly, wrapping her small hand around my larger one holding my phone. "You can give me feedback. All I ever get are gross dudes in my DMs trying to get nudes."

She glanced up at me.

"Don't worry. I almost never send them any. Though," and she leaned close to whisper in my ear. Her breath was warm against my lobe. "I have plenty I could send them. If I wanted to."

My cock twitched at the feeling of that warm air on my skin, the words bringing to mind images of her naked. I was very glad that the blanket covered the bulge in my shorts.

"We really shouldn't," I said weakly. I had lost control of this situation by now. I was trying to keep this from getting out of hand but...was my heart really in it?

"It's fine," she said. "Don't think too hard about it. And speaking of hard..."

I coughed again, in shock this time as her hand darted under the blanket and suddenly gripped my cock through the material of my shorts. I looked at her quick with my eyes wide and shook my head.

"Don't," I whispered, moving my hand down to try and move hers.

"You don't," she whispered back. "Don't cause a scene."

She was right. I couldn't think of a way to fight her off without this becoming visible and then, who knows. Kristen would freak out. Bad blood between the sisters. And who's fault would it be? Mine. So, I just sat there, my sister in laws 19 year old hand wrapped around my cock.

"I just want to know what photos are the most...effective. So let's look and I can judge what you like." She gave my cock a quick tug and smiled at me.

"This is real nice," she said, voice low so that only I could hear. "My sister is sooo lucky."

I grunted non-committedly. I knew I had a decent cock. About 7.5 inches long and pretty thick. Not so big that it would terrify someone but plenty to fill someone...my wife! To fill my wife and no one else, I reminded myself desperately.

Jenny began to scroll through her photo feed and I watched the screen helplessly. There were a lot of photos. I wondered how long she had been doing this? As we scrolled through her hand was lightly gripping my length, not stroking but the heat and weight of it always there.

As we passed a photo of her kneeling on a bed, wearing only a chunky cardigan sweater tied at the waist. Her legs were open, the space where they met shadowed but the sweater but my imagination filled in the information that she was without panties. Both of her shoulders were bare as the sweater dropped off of them and it hung open, revealing the inside curves of her breasts stopping just shy of her nipples. My cock jumped when I saw this image and Jenny chuckled.

"You like that one?" She asked. She began lightly stroking my length. "The sweater does it for you?"

"Stop," I said weakly. She did not.

"I have a lot more photos from that session," she purred in my ear. "I couldn't upload them though. Instagram sucks and I don't want to get banned."

"Here," she said, dropping my hand and phone, and pulling her own out. I watched as she opened her photos and my eyes widened as I saw folder after folder of photos. She quickly found one and opened it and I saw her in her sweater. She did this all with one hand so she could continue to lightly stroke me.

"There we go," she said as she showed them to me. There was the one that got posted, but there were plenty more. Soon there was one where the sweater had fallen away and her full breast was on display, her nipple a hard light brown button with the circle of her areola around it. I grunted instinctually and she squeezed me making me sigh.

"Yeah, I thought these were sexy too," she said. "I got so turned on taking these photos. I was dripping wet. See?"

The next photo had her leaned back with her knees further apart. I could now see her pink pussy lips, completely devoid of hair, parted slightly.

"Look close," she said. "You can see how wet I was."

Sure enough there was a glisten on the lips. I swallowed hard.

"You shouldn't show me this," I whispered but did not take my eyes away from the image.

"I always get horny when I take the photos. I think of guys looking at me, jerking themselves. Like this..." she pumped my cock hard a few quick strokes. I could feel the foreskin of my cock slide across the swollen head, lubricated by my pre-cum. "And that's so hot, you know?"

She grinned at me.

"I'm wet right now."

She removed her hand from my cock and I sighed. It should have been from relief, but really it was from disappointment.

She gripped my wrist and pulled my hand towards her and placed it, palm down on her upper thigh. There are plenty of things I should have done but at this point..I was gone. I didn't care that my wife was a couple of feet away from us. That my marriage could end at any moment if we were caught. I just felt the young flesh under my hand and reacted.

Jenny was tugging on my wrist and I let her lead it higher. The smooth skin of her thigh slid under my hand, feeling like perfect silk under my fingers. I could feel the heat of her sex before my fingers reached it and I didn't notice that she had removed her hand from my wrist and I was moving on my own now.

Her legs were parted and my searching fingers met fabric. I lightly traced the edges of it, finger tip following first up one of the angled seams then down and up the other. I heard her groan softly as I did that.

My fingers returned to the fabric of what I could now tell was a g-string and traced across the fabric down to where it hugged the lips of her pussy, the source of the heat between her legs. I could feel how damp it was. She had not been lying. She was wet. Very wet. I pressed against the panties, pushing the wet spot between the lips, rubbing softly making her moan quietly against my ear.

In the meantime her hands had moved back to my lap. I was focused on stroking her sex so I didn't register as she popped the button of my pants and opened the fly. I felt her reach in and quickly and with skill pull my full hard cock through the front of my boxer briefs.

"Ohhhhh," I groaned quietly as she gripped me and began to stroke.

I moved my fingers to the side and pushed them under the fabric of her panties and pulled them to the side, exposing her pussy to the same air that my cock was feeling against it. I pushed my finger between her lips and rubbed across her clit making her hiss in her breath, along the velvet channel, finally to her opening where I hooked my middle finger and pushed it up into her hot wet cunt.

"Oh fuck, finally," she moaned into my ear and began to stroke me faster. I checked and confirmed that there wasn't too obvious movement in the blanket that covered us. We were relatively safe in that regard.

"You are so bad," she said, her voice husky now. "Finger fucking your sister in law right beside your wife!"

"Shut up," I hissed, not wanting anyone to hear us over the music that Bill had blaring. I pulled back my finger and added a second one before pushing back into her. I placed my thumb against her clit and she moaned again. Slightly louder this time.

"Or what?" She said, teasing. "Will you punish me? Like you are my daddy? Want to spank me daddy?"

I gritted my teeth and pushed my fingers deep into her while rubbing her clit with my thumb. No woman had called me daddy before and I'd be lying if I said it didn't make my cock twitch in her hand.

She moved her hand up and rubbed across the top of my swollen head and coated her palm with my pre-cum and then rubbed that down my shaft. Her hand left my sex and I groaned with disappointment but had to smile as she raised it to her mouth and licked my pre cum off of her.

"Tasty," she said before gripping me again.

We were keeping pace with one another now. As she stroked down on my rigid pole I'd push my fingers into her. As she pulled up I would pull back. And on and on, our breath heavy. I watched her face as we pleasured one another. Her eyes were half closed, her plump lips parted slightly. Occasionally I would glimpse her tongue dart out and run along them.

"Oh fuck," she whispered. "I'm getting close. Don't stop." I watched as she slid her free hand up her body, around the curve of her heavy breast, fingers finding her hard nipple which he began to pinch and tug.

"Grab my tit," she hissed. "Pinch me, daddy!"

I didn't need any more invitation. I had been looking at her young breasts for years and now was my chance. I placed my free hand, the one not fucking her with my fingers, over her other breast and squeezed, feeling the hard nipple against my palm. It was heavy as I lifted it, but firm, with next to no sag. My fingers found her nipple and I rubbed my thumb around it, rolling it. Then I pinched it between my finger and thumb.

"Oh fuck, daddy, yeah, just like that," she gasped.

She sped her hand on my cock and I matched her pace with my fingers inside of her. She was moaning quietly as I chased her climax. I was slightly worried about that but at the same time my own release was building.

"Oh," she gasped. "Oh, oh, oh..."

I could feel her inner thighs begin to quake against my hand and knew she was almost there. I sped up my fingers, a quiet wet sound coming from under her blanket at my fingers drove in and out of her sopping pussy. My thumb pressed hard against her clit and I pinched her nipple hard one last time making her gasp and then begin to squeak.

I released her tit and slapped my hand over her mouth, muffling the noise that was building as she began to orgasm. I felt the muscles of her cunt clamp down on my fingers and wished that I could feel that on my cock.

I continued to finger her as she created and then rode the wave of her climax, humping herself against my hand. She continued to grip my cock but was no longer pumping it. Now it was acting like an anchor for her to hold as she came. She was moaning against my hand, the sound muffled as I held her in place. Finally she tensed, her legs shooting out straight.

"Ohhhhhhhh fuuuuuuuck," she groaned against my palm.

As her climax subsided I kept my fingers in her, stroking slowly now as I brought her down from her crest. She was panting and I could see a glisten of sweat on her brow and across her chest above the tube top.

Thank you," she whispered. "I needed that."

I smiled at her in the dark. Happy that I had brought her pleasure. Not caring for the moment the consequences of what we were doing.

"I didn't forget about you," she whispered as she resumed stroking my hard cock. "Are you close? We'll be home soon."

I nodded. I was close. Watching her cum from my fingers was so sexy that I was on my own verge.

"Let me know when you are about to cum," she said and sped up her hand.

It didn't take long. Maybe one or two minutes more, but who could tell I was lost in the pleasure of her young hand gripping me, rubbing me.

"That's it, daddy," she whispered in my ear. "Cum for me. Don't you want to cum for your babygirl? Aren't I your princess, daddy? Don't you want to cover me with your cum?"

The dirty talk mixed with her clever hand were enough. I could feel it building. I could feel my ballsack tighten and that bright light feeling at the deepest base of my cock build.

"I'm going to cum," I whispered crying suddenly realizing that there was a problem. "There will be a mess..."

She just grinned, looked into the front of the car, seeing Bill lost in his own world and her sister, my wife, asleep and lifted the blanket and ducked her head under.

Within a second a wet warmth enveloped there head of my cock as she took it in her mouth. She continued to pump the shaft as she began to suck, rolling the purple head around her tongue.

That was enough and I groaned as quietly as I could as I began to release into her 19 year old mouth. I placed both of my hands into her thick curly hair and made fists, holding her in place as I came, spurt after spurt of hot cum. I could feel her sucking and swallowing as I pushed myself deeper.

Finally I sat back, letting my head fall against the seat behind me. My cock still twitching in her mouth as she made sure to suck up the last of my seed.

She came up from under the blanket and I could see a glob of my creamy cum on the corner of her mouth. She moved her finger up and pushed it between her lips and swallowed again.

"Thank you for that, Daddy," she whispered. She looked around and smiled. She tucked my cock back into my shorts and did me back up.

"Almost home," she announced as she moved back to her side of the back seat. I was catching my breath and looked around surprised. She was right. We had finished up just in time.

I watched as she wiggled around in her seat, reaching up under her skirt. She then held out her hand to me and placed something in my own. I looked down and saw that she had passed me her little g-string.

"Something to remember me by," she whispered.

I quickly pushed the panties into my pocket and looked at her amazed and confused. The realization of what we had done came down on me like a ton of bricks falling.

I had cheated on my wife. With her sister. What the fuck was I doing? Had I just ruined my wife for a handjob in the back of a car?

We pulled into Kristen and Jenny's father's house and Jenny popped the door open and scooted out. The stop had woken Kristen and the two sisters said goodbye.

Jenny looked at me and smiled.

"Thanks for keeping me company for the ride, Mark," she said.

"Uh," I stammered. "No, thank you."

After she walked up to the door and went in we pulled away heading for our own home.

"I'm glad that you two get along," my now awake wife said. "That makes me happy."

"Oh," I said, running my fingers over Jenny's panties in my pocket. "Well. If it makes you happy I'll make sure we keep getting along."t had been two weeks since that night in the car. That night when Jenny, my 19 year old sister in law had jerked me off and finished me with her mouth in the backseat while my wife slept in the front. I had brought her to climax with my fingers as well, covering her mouth with my hand as she came.

The guilt over that indiscretion had hung over me like a black cloud since. It had been so stupid. So reckless. I'm 40 years old. I should have known better. Controlled the situation. But I had let the young girl carry me away. I did what I did and I have (hidden away) the panties she had worn that night as proof of my crimes.

It wasn't all bad, actually. In those two week's my wife, Kristen, and I's sex life had greatly improved. We had been married for 11 years and while we both still were attracted to one another we had not been having sex as regularly as in the past. Like most couples we had fallen into a pattern of maybe once a week. But since the night with Jenny my libido had gone into overdrive. We had been making love several times a week and Kristen was happy about it.

The problem was that, while my wife was still sexy and beautiful, when I was fucking her, it was Jenny who was in my mind. It was Jenny's full, 34D breasts I was sucking on, Jenny's tight pussy I was driving my cock into. Kristen had no idea but every time we slept together I was, in my mind, cheating on her with her half sister.

In my defense, Jenny wasn't helping. Or rather, she was. Too much. I was getting multiple messages from her daily and they were not the kind that I could share with my wife.

The day after the eventful trip in the back of the car I woke up late. Kristen had already been up, made coffee and left for work. I had planned on working from home and didn't have much I needed to do before an early afternoon call so I took my time grabbing a cup and, dressed only in a comfortable robe, sat out in the backyard beside the pool enjoying the morning sun.

I had my phone and, as I always do, opened up Instagram and began to scroll. That was when the memory of the previous night came down on me.

Oh fuck, what had I done? I had managed to, after tossing and turning for a couple of hours, managed to suppress the memory of the last night but seeing the app brought it flooding back.

Then I noticed that I had a message waiting for me. I swallowed. Could it be from her? My finger shook slightly as I pressed the tab to open it.

Of course it was from Jenny, from her sexy photo account, @jennyhazfun88.

I opened the message and quickly read what she had written.

Hey daddy! Hope you had a good sleep. I've been thinking about you. About your cock. I woke up so horny and have been playing with myself, remembering how it felt in my hand. How you tasted when you came in my mouth. How good it felt with your fingers inside of me.

My cock was immediately hard reading this. My own memories of the night before flooded in, this time less tinged with guilt.

I shook my head. This was a mistake and I had to end it. I typed a reply.

Hey. I'm sorry about last night. We can't do that anymore. Let's forget it before we hurt Kristen.

Send.

I saw the dots that said that she was typing a reply. Shit! I hadn't realized that she was online and logged into the site.

Nope! I can't forget. I won't. We won't hurt Kristen if we don't tell her. I won't tell if you don't. I'm still playing with myself btw.

I groaned.

I mean it, I typed. I can't do this. I'm flattered but this is crazy. I'm married to your sister. I'm old enough to be your dad!

There was a pause. I hoped against hope that this had ended things. I began to scroll through the photos on her account again while I waited. I knew I had to stop but one last look through couldn't hurt any more I rationalized.

I got another message. I opened it, expecting to find a written reply but instead there was an image. I groaned in...dismay? Lust? I wasn't sure anymore.

Jenny was naked on her bed, the same one from many photos on her feed, but this time, instead of images where she carefully covered herself to meet the decency standards she was clearly and fully naked.

She was laid on her back and holding the camera out from her. Her full breasts were free and despite her lying on the back still pert. Her brown nipples were clearly hard. Her face was free of makeup but still stunning. Her green eyes were focused on the camera as if she were looking right at me. The freckles that danced across the bridge of her button nose and over her cheeks were cute as always.

Without thinking about it, I reached into my robe and gripped my hard cock.

I told you I was thinking about you, she typed next. See how hard my nipples are for you, daddy? I've been pinching them like you did last night. Imagining you were doing it. Know what else I was doing?

I could only imagine.

Stop, I sent back. You have to stop.

The next thing she sent was another photo. Actually a series. This time the angle was different. She had the camera down between her legs and in the first photo she was spreading the pink lips of a perfectly clean pussy. The lips glistened. She was clearly very wet.

The next photo showed two fingers inside of her. The next was her upper body again this time eyes closed, head rocked back against her pillow, plump lips parted.

That's what else I've been doing. All morning. Thinking about you.

I was now stroking my cock while looking at the photos. I couldn't seem to help myself. She was just too sexy.

What are you doing? She sent. Are you touching yourself? Are you hard?

Both of those were true of course but I refrained from answering.

Tell me, she said. Tell me and I'll give you a treat.

I wondered what she meant by that. What would she give me! Did I want whatever it might be? Did I refuse?

I couldn't help myself. I needed to see what kind of treat she was talking about. Finally I shook my head and typed;

Yes.

The wait, while only a minute or two, was painful. I needed to see what she would answer. I dreaded what it might be.

Finally I got a message, not on the app this time but as a text message. I opened it and saw that she had sent a video. With eager and shaky fingers I opened it.

She must have set her phone on some kind of tripod. Which made sense considering the photos she had uploaded to her account. The view was of her bed, and her upon it.

She was fully naked, her skin smooth and pale. She was sitting up against the headboard and one hand was gripping her pert breast, the nipple peeking between her fingers. The other hand was between her spread legs, fingers pushing the lips of her bald pussy apart, clearly wet from her previous play.

"I'm thinking about you, daddy," the video-her said. "I'm thinking about how I wish you were here."

She began to knead her own breast and then tugged on her nipple. The other hand began to run slow circles on her clit.

"I'm wishing it was your hands on me. That you were here right now playing with me."

She slipped a finger easily into herself, the digit disappearing into her wet hole.

"I wish your finger was in me. Actually, not your finger. I love your fingers but right now I wish it was your cock. Your big daddy cock piercing me. Stretching me. I'm very tight. My cunt would grip your big cock. Squeeze it."

She added a second finger to first and began to slowly slide them in and out of her.

"Would you like that, daddy?" She asked the camera. "Would you like your princess to be under you? You inside? Do you want to fuck me?"

She seemed to be done talking at this point. I could hear the wet sounds of her fingers tucking her 19 year old pussy. As I watched I held my phone in one hand and stroked myself with the other. The foreskin of my cock slid back and forth over the swollen head of my cock, my pre-cum making it slide easily.

She was moaning as she fucked herself, not really words, but I could make out her saying 'daddy' several times. Each time she did it was like an electric current of lust straight to my manhood. I had never had a girl call me daddy before and, I found, I liked it a lot.

Then the video stopped. I paused my masterbation and swore. I had been very close.

My phone rang. It was, of course, her.

"H...hello," I stammered as I answered.

"Hey daddy," her voice came through. "Did you like that video?"

"Look, Jenny," I said, trying to take back control of the situation, despite the fact that I still gripped my manhood. "This is enough. We aren't doing this."

"Doing what," she asked in a voice that conveyed the pout I knew she was wearing. "We aren't really doing anything, are we? Just talking. A lot less than we did last night, right?"

"You know what I mean," I said. "I can't cheat like this. It's not fair to Kristen. I love her."

"I love her too," Jenny said. "And if she doesn't find out she won't be hurt. Don't make me tell her. That would break her heart."

My eyes widened and I swallowed past a heavy lump that suddenly formed in my throat.

"You...you wouldn't. You can't!"

"Ok," she said. "I won't. But you have to do something for me first. It's simple."

I was wary but I was also desperate to know what she wanted from me.

"Okaaay," I said.

"Oh good!" Her voice was bright and happy sounding. "You still have my little gift I gave you? You know what I'm talking about."

Of course I remembered her gift. I had been unable to figure out any way to get rid of those panties last night before bed. They were still in the pocket of my shorts.

"Yeah. I still have them."

"Good. Go get them. I'll wait."

I blinked, tried to will myself to resist but then just simply said, "OK," and headed upstairs to my and my wife's bedroom, digging the panties out of the pocket of the shorts I had been wearing.

"I have them," I said.

"Good," she said. "Now I want you to wrap them around your cock. You've been playing with yourself haven't you? Pretending that it was my hand wrapped around your big cock?"

"Yes," I said again. I had quit pretending to resist at that point. I took the panties in my right hand and then re-gripped myself sliding the thin silky material over my cock.

"I'm doing it," I said and sat on the edge of my bed panty wrapped cock in my hand.

"Good," she said, her voice husky. "Good daddy. Jerk yourself for me. Cum for your princess. I have my fingers inside of me. For you, daddy. I want you to cum and I want to hear it. Cum for me."

As she spoke I began to pump myself, chasing my orgasm. Her voice was husky with what sounded like lust and she was beginning to moan.

"If I were there I'd let you cum anywhere you want, daddy," she said. "I'd let you cum all over your princess' tits if you wanted. On my face. In my mouth."

"Oh, fuck," I groaned, the image of Jenny with my spunk coating her pretty face, smeared across her freckles.

"You like that, Daddy?" Her voice was almost a whine now. "You like the idea of covering me with cum. I'd let you. Anytime you want you can cum all over me."

I was breathing heavier now.

"I'm close," I whispered into the phone. "So close."

"Where do you want to cum today?" She asked between moans.

"On your face, princess," I said, calling her that for the first time. "On your fucking face."

"Do it then, daddy! Cum on me! Please, pleeeeease! Give me your cum!"

That was enough. I grunted and groaned as my muscles tensed. I squeezed my cock as I released, spraying rope after rope of cum across my thighs and onto my bedroom floor.

"Oh shiiiiit," I groaned as I continued to milk myself as the aftershocks of my orgasm made my cock twitch in my hand.

"Thank you daddy," Jenny said. "Thank you for giving me what I needed. I have to go. But I need you to send me a picture. A picture of my panties wrapped around your big cock."

She hung up. I was left sitting there, cum all over my legs, in a puddle on the floor in front of me. Before I let myself think any better of it I opened the camera on my phone and took a photo of my crotch, the thin panties hanging off of it, now soiled with my seed. You could see the mess I had made. I closed my eyes and hit send.

My heart was beating. I knew I had made a terrible mistake. It was one thing to receive photos or videos. I could delete them. Having sent one out though...I had no control over that image once it was gone.

Very nice, she texted me after a minute. Thank you, Daddy. I have to get ready for class now. I'll be thinking about you all day. I hope you think about me.

And I did. I couldn't get her out of my mind at all!

This continued for the two weeks. Every day she would send me photos of herself. She would record videos of her playing with herself and send them to me. I would sneak into the bathroom at work, jerking off while watching them with headphones in my ears.

She would ask me for photos of myself, and even, a couple of times videos of me masterbating. I would send them and hate myself for it.

Despite my frantic self-pleasuring I could not calm my libido every night I would find my mind wandering to images of Jenny and I would roll over and grab my wife fucking her while I thought about her sister.

Finally, I couldn't take it anymore. Despite what it might do to my relationship, how it might destroy my happy life, I decided I had to tell Kristen. I would admit my wrong doings and then we would see where we went from there.

I spent the entire day neglecting my work thinking about this conversation. Preparing for it. I drove home slowly, delaying the inevitable arrival.

Eventually I dragged my feet through the door. I went into the kitchen where Kristen was leaning against the counter talking into her phone. She seemed to be finishing up her conversation. Finally she hung up.

"Hey great news," she said before I could speak. "That was Jenny. The three of us are going to spend next week at Dad's cabin! Won't that be fun?!"

I closed my eyes and tried not to sigh.

"Yeah. I'm sure it will be. Really fun."had always loved to visit my wife's family cabin. Her grandfather had bought and built it when he was a young man so it was a generational thing, with the expectation that my wife and her younger sister would inherit and share it eventually.

It was small and had not had the million dollar rebuild that most cabins on the small lake had. It was rustic and simple but it had two bedrooms, a cot in the living room, an outdoor shower, a working plumbed toilet-thank god-, a simple boathouse on a dock and a strip of sand beach. It was on a kind of cove so there were no neighbors at that end of the lake making it very secluded.

Any chance we had to get up to the lake, escape the city and relax I was always eager to take. This weekend, however, I was dreading it because it wasn't just going to be my wife, Kristen and I. Her 19 year old sister, Jenny would be coming too.

Two weeks previously Jenny had jerked me off in the backseat of a car with my wife sitting in the front street. It had been wonderful but a terrible mistake. My wife and I had been married for 11 years and I loved her. I had no intention of fucking that all up but...Jenny with her full tits, young body, curly brown hair and cute freckles across her button nose was hard to resist.

Jenny and I had been sending each other images and videos since the eventful night in the car. She would send me nudes and videos of her fucking herself and I would send photos of my hard cock. She would call me and moan into the phone while I jerked off in the bathroom at work. It was exciting and sexy and the worst thing I could be doing. But at least, thus far, it had been limited to online.

Now she was coming to the cabin with us and I couldn't see her leaving me alone.

I tried to call off the trip. I claimed I had too much work to do but Kristen would have none of it.

"Mark," she said, finally angry with me. "We are going to the cabin and there is no way around it. You will relax and have fun! Also," she added, "you promised my dad that you would strip and re-paint the boat. No one can take it out if you don't do that!"

I had no choice. I was going to the cabin.

++++++++++

It had been a hot summer with temperatures staying steady over 30 degrees celsius and very little rain. It was honestly going to be great to get out of the city.

Because of my wife's motion sickness I was driving our car, an Audi Q3, and we swung by her father's house to pick up Jenny.

I was waiting in the car as she came jogging up carrying her bag. It was a sight that made me groan inwardly. She looked amazing.

She was wearing a loose, mid thigh length skirt and a yellow, string bikini top. Her breasts, 36D, were barely covered, and they swung magnificently as she moved towards us smiling.

"Jenny!" My wife said as she got into the car. "What are you wearing?"

"Oh, I'm going straight into the water when we get there," Jenny said. "I wanted to be ready."

"It'll be cold in the car on the way up," my wife said. "You know I'll need the AC on so I don't get sick."

"I'll be ok," Jenny said offhandedly. "Hi Mark! How have you been?"

She knew exactly how I had been. Horny and hard since I had last seen her. I was jerking off more at 40 than I had since I was 15 because of her.

"Good, not too bad," I said, tearing my eyes away from her perfect breasts to meet her eyes. She was grinning and the eyes danced with mischief. I knew I was in for trouble.

It was about a two hour drive to the cabin and Kristen,like she always did, quickly laid her head against her window and went to sleep, the only reprieve she had from carsickness.

Jenny was in the back seat, with headphones in, scrolling through her phone for the first half an hour or so, as we left the city. I was able to look into the rear view mirror and see her and spent probably too much time glancing into it, watching her.

Eventually she looked up, then leaned between the seats and checked to see if Kristen was asleep. Once she was satisfied she was she reached up and angled the rear view down more so I wasn't really able to check traffic behind me. The focus was on her sitting there.

She slid into the center of the bench seat and grinned wickedly at me. I glanced at Kristen and shook my head at Jenny in the mirror. This was about to be a mistake, I knew.

She ignored the head shake and slowly traced her finger along the edge of the fabric of her bikini top, slowly running up and down the line where it met her exposed flesh. I could see that her nipples were hard, little nubs that tented out the yellow fabric. We could say that it was from the AC, but knowing her, it was my eyes on her body that caused them to harden.

She locked eyes on the mirror and smiled slyly as she pushed her finger under the bikini top and then tugged it to the side, freeing her brown nipple and areola. My cock had already fully hardened by this time and I let my hand drop to my lap, lightly gripping myself lthrough the fabric.

She slowly traced her finger around the hard nipple before gripping it between her finger and thumb, tugging on it. Rolling it in her grip.

Her lips were parted slightly and I knew, from our online dalliances, that she was enjoying herself, making herself very horny. I was lightly squeezing myself, not wanting to go too far. I didn't want to wake my wife or cum in my pants, making a mess.

Jenny exposed her other breast and was now playing with both of her nipples, teasing, tweaking. My eyes darted from her to the road to keep from crashing and back to her. Her head was tilted back now, enjoying what she was doing to herself.

One hand left her chest and she slid it over her smooth belly to her skirt which she lifted up. Under I could see the matching string bottom to her bikini, knowing what that cloth hid. A perfect pink, shaved pussy. I had seen many photos and videos of it and, on that ride a couple of weeks before, had my fingers inside of it.

She pulled the fabric of the bottoms to the side giving me an in-person view for the first time in a long time. She was perfectly shaved, and she parted the glistening lips with two fingers to show me how wet she was. Her clit was hard and she began to rub it. I could hear her make a small moan and looked over at my wife to confirm that she was still asleep.

We continued like this the rest of the trip. Her slowly, sensuously playing with her hot young body, putting on an extended show for me. I gripped myself and gently squeezed and tugged. Keeping myself under control. By the time we pulled into the rutted dirt road that led to the cabin my balls aches for release.

A jolt from a dip in the road that I didn't notice because my eyes were locked on the young thing in the backseat shook us all. Kristen moaned and opened her eyes looking around confused.

Jenny in the back, quickly shoved her tits back into her bikini and pulled down on her skirt, managing to cover herself before my wife turned and looked into the back seat.

"Oh, sorry Jenny," Kristen said. "The ride must have been so boring. I just can't keep my eyes open."

"I know," Jenny said. "It's ok. I kept myself amused."

I rolled my eyes at that.

We pulled up to the cabin and while my wife got out I arranged my still-hard cock so it was poked up, held in place and hidden by the waistband of the shorts I was wearing.

"I'm bursting!" Kristen exclaimed and began hurrying to the bathroom inside. "Mark can you start unloading?"

As soon as she got through the door, Jenny moved, quick like a viper, to stand in front of me.

"That was crazy, Jenny," I started to say but was cut off when she grabbed the sides of my head and pushed her lips against mine, kissing me. Without thinking I opened my mouth to her probing tongue and we kissed for a moment. it occurre to me, through a fog of lust that came over me that this was our first kiss.

She took one of my hands in hers and moved it up to her breast. I closed my hand around it, feeling the hard nipple under my palm. I groaned into her mouth as she reached forward and gripped my cock through my shorts.

I was breathing heavily when she suddenly stepped back.

"It's good to feel your hand on me again, daddy," she said. "And don't you call me Jenny when Kristen isn't around. I want you to call me princess."

"Jesus Christ," I said. "That's a mistake. We can't be doing that!"

She just laughed and stepped against me again. I could feel her young, firm breasts press against me. Instinctually I placed my hands on her round hips.

"Later," she said quietly, "when you fuck my sister I want you to imagine me. Make her cum loud so I can hear it. I'll be in the next room playing with myself."

Then she stepped away from me and began jogging down the sloped path that led to the water, pushing her skirt down as she went. I watched her round ass bounce as she ran away from me.

"Going to jump in the water!" She called over her shoulder as she went.

I sighed, readjusted my hard cock and began unloading the car.

+++++++++

It didn't take too long to get settled in. The cabin was mostly stocked with essentials. We had brought food for grilling and plenty of beer and wine. In less than an hour we were all sitting on loungers by the water, enjoying the heat. Later, we had decided, we would play some cards and eat.

Jenny behaved herself, mostly. Beyond looking like a fuckable sexpot she didn't make any moves on me for the evening. Occasionally she'd meet my gaze and hold it for a moment too long but not in a way that Kristen could suspect anything.

Eventually, after a few drinks, some cards and laughs we decided to call it a night. Kristen got up to get ready and Jenny leaned across the table.

"Remember, Daddy," she whispered. "When you fuck her, that's me you are fucking. Make it a good one."

Then we went to bed. We had the larger room with the queen bed and Jenny had the adjacent, smaller one. The bedrooms shared very thin walls. It wasn't hard to hear what was going on on the other side so usually Kristen and I, when we made love with other people there, were as quiet as possible.

That night, having been driven crazy by Jenny's earlier teasing, I was hard as a rock when we entered the room. Kristen was wearing an oversized tee shirt and panties. I took a moment to admire her. She was 38, but she still looked good. Her breasts had not sagged much, and she kept herself in shape. I knew I was lucky to have her and was a fool to risk her for her younger sister.

Still, it was Jenny on my mind when I reached for my wife and pulled her against me, pressing my hard cock into her stomach.

"Mark," she giggled, "careful. Jenny might hear."

"It's ok," I said. "I saw her put earplugs in when she went to bed." This was a flat out lie but I didn't want Kristen to hold back.

I picked her up and dropped her on the bed as she laughed. I gripped each of her thighs and pushed them apart, putting my face in her crotch and inhaling the scent of her sex. It was good but I remembered the slightly different smell of Jenny on my fingers after I had fingered her.

I gripped the hem of the panties and drew them down quickly making Kristen gasp. I dove in before she could say anything and my tongue lapped along her pussy, over her vagina and swirling around her clit.

One thing about being married so long, I knew everything about getting Kristen off with my mouth. I had studied the subject well and was quickly licking and sucking her clit while two of my fingers stroked her pussy, digging in and rubbing her g-spot.

It didn't take long before she was gasping for air, moaning and whimpering from my mouth. She had her fingers in my hair, holding me in place as her hips rose against my tongue and mouth, pushing my fingers deep into her.

I took her to the very edge of her orgasm. Concentrating on her pleasure actually drove Jenny from my mind temporarily, so focused i was on my wife at that moment. Then, as I felt her breath catching, knowing she was on the very edge, I abruptly stopped.

I held her there as she gasped.

"Mark," she said, frustrated. "What the fuck. Keep going. I'm so close!"

I ignored her and slowly stroked my fingers I her, keeping her just on the edge.

"I want to be inside you," I said, not shouting but loud enough that I knew Jenny could hear if she was listening.

"Ok," Kristen gasped. "Get up here."

I continued to stoke and occasionally lick.

"I want you to ask me nicely," I said with a smirk.

"Oh fuck, Mark," she said, starting to whine, "c'mon and fuck me."

"Say please."

She paused. Stubborn. But finally she said it.

"Please."

"Louder,"'I demanded.

"God damn it! Please."

"I can't hear you."

"Mark! Please fuck me!"

It was loud enough I figured. I moved quickly up her body and aiming at her sex sank into her in one thrust.

She had started out trying to be quiet but that was done now. She had long forgotten that as I slammed myself into her again and again. She moved from moaning to squeaking to demanding loudly for me to fuck her hard.

It was an amazing sex session and it should have been more than enough for me but as my cock sank into her again and again I imagined it was Jenny's tight cunt wrapped around me. My eyes were closed but Jenny's cute face was the one I saw in my mind.

Finally I felt my climax building and I sped up even more. Kristen was repeating "oh fuck, oh fuck," over and over again. I couldn't hold back any longer and my fingers dig into Kristen's hips, my back arched and I released into her, moaning, collapsing on her.

After I caught my breath I rolled off and lay on my back, my cock, wet with my cum and her juices, still twitching.

"Wow," Kristen said, laughing softly. "That was amazing. I hope Jenny didn't hear."

I shook my head.

"I need some water," I said and got up, pulling on my shorts. I left the room and walked towards the kitchen. As I passed Jenny's room I saw the door was open. She was sitting up in bed, and our eyes locked. She has raised her arms and mimed a light golf clap. I grinned and made a courtly bow and got my water before heading to bed and collapsing, falling asleep within minutes.

++++++++

The next morning I woke last. I could smell coffee and bacon, my two favorite smells in the world. I groaned and rolled out of bed, pulling on shorts and a tank top and joining the girls at the table.

"Good morning," Kristen smiled at me. She was always happy the morning after a good fucking. I smiled back then glanced at Jenny. She was also smiling. A secret smile that only the two of us understood.

I grabbed my coffee and mused that I might go for a run.

"Nope," Kristen said. "You know you have to scrape and paint the boat. No fun until that's finished!"

She was teasing but she wasn't wrong. It was a big job that needed to be finished and if I could get away with skipping it I would.

The girls had decided to spend the day on the beach in the sun. I grumbled how that must be nice but, in reality, I welcomed the reprieve from Jenny's looks. She was very difficult to ignore.

Today's bikini was even skimpier than yesterday's, but this time in white and blue stripes. Her assets jiggled each time she moved and I had a hard time keeping my eyes off of her.

I grabbed a big bottle of water and while the two of them headed to the sand I grabbed my tools and went over to the boat.

It was an old boat, 15 feet long and made of wood. Last time we had come down I had hauled it out of the water, removed the engine and flipped it onto a couple of sawhorses. The paint was still the original and it was peeling and discolored. If it wasn't taken care of soon the boat would begin to rot away.

I put in headphones and took my hand held scraper and cursed not having some kind of power sander and began to work. It was a hot morning and before too long I was sweaty and uncomfortable. I peeled off my tank which was dripping with sweat and got back to work scraping away the peeling paint.

I keep myself in good shape for my age so I didn't have a gut and even a few abb muscles on display (a four pack maybe), so I guess I looked ok shirtless in only a pair of mid thigh red swim trunks. Flakes of old paint stuck to my sweaty skin.

I was working on the side of the boat that was opposite the girls. With the boat between myself and them. I was lost in the repetitive work and music when I noticed someone approaching me.

Of course it was Jenny. She had her eyes locked on me and, without trying, her body swayed sexily as she came towards me.

"Jenny," I said, raising my hand to try and signal her to stop. She didn't even slow.

She came to stand directly in front of me and then dropped to her knees.

"Kristen is asleep," she said. "She'll stay that way unless you wake her up. You don't want her to wake up do you?"

I really did not.

For one, I had no idea how I would be able to explain away my sister in law kneeling before me. For another, she had already pulled her bikini top aside and set free her perfect breasts. I wanted nothing to interrupt that view.

As I looked down at her, dumbfounded she reached forward and in one move yanked my swim trunks down and my cock, which had already started to harden as soon as she was walking towards me sprang free.

I was not a porn star but I had a decent cock, I figured. It was about 7 and a half inches long and pretty thick. I was uncircumcised so the purple head hair peeled out from its sheath of skin sunlight catching the small amount of pre-cum that was forming on the tip. I did not shave but I kept my pubic hair trim so my cock was not half buried in a thatch of hair.

"Oh fuck this is nice," Jenny said quietly and gripped my cock, it filling her small hand. It was soft and I groaned with pleasure as she began to pump it.

"Oh fuck, it's just as nice as I remembered," she said quietly. "Does Kristen love this cock like I do?"

I didn't have an answer for that. She didn't seem to need one. She shuffled, straightening her legs to be higher and placed my cock between her breasts. She must have just applied lotion because as she pushed her beautiful globes together and began to slide me between them I moved easily, the only friction being pleasurable.

"Does Kristen do this for you, daddy?" She asked, making eye contact as she used her tits to fuck me. "Does she let you fuck her tits like this?"

"No," I said quietly. I was thrusting now, unable to help myself. The feeling of sliding between her melons was too much to hold back. My hands, shaky at first then determined, lifted and gripped her breasts on either side, squeezing them tighter around my rod.

Despite having seen them daily via messages, this was the first time I had touched them since that day in the car. The skin was smooth and firm, her 19 years had done nothing to make them sag. She giggled and removed her hands, letting me take over the fucking.

She reached between her legs and slid one hand under her bikini bottom and I could see that she was rubbing her clit.

Each time I thrust the purple head of my cock would be exposed, foreskin pulled back. She angled her head so that she could lick the tip each time it emerged from her cleavage.

"I want to do anything she doesn't do for you daddy," she almost whined. "I'm yours. I'm your slut, aren't I? Tell your princess I'm your slut."

"Oh fuck," I grunted, lost in the feeling. "You are. You are my slut."

"Call me Princess."

"You are my princess slut."

She moaned at that and then leaned back, my cock sliding free of her magnificent tits. I grunted again, this time with frustration but it was short lived.She gripped the base of my cock and then opened her mouth. She looked up at me and smiled.

"Fuck my mouth, daddy," she said sweetly. "Don't be gentle."

Then she sucked me in, slowly sliding down the length. I watched the inches disappear, further than my wife ever took me. I felt the head hit the back of her throat and she gagged a bit, then continued to push me into her. It was only a couple of seconds, I suppose but it felt like minutes before her nose touched my stomach.

Her hands were on my hips, pulling me into her. My hands went up and sank into her curly brown hair and I pulled her even deeper for a moment. I could see tears dripping from the corner of her eyes, and feel the gag reflex squeezing the head of my cock, before I let her back, half of my cock pulling out.

Then I thrust my hips, driving into her again.

I suppose it was at that moment I gave up. Thus far I had been mostly passive. She had led the way down this path. But it was then, driving my cock into her eager mouth, feeling myself sink into her throat, her face, tear streaked but happy, that I figured it out.

She was my slut. She was there to please me. And why shouldn't I be pleased? Why shouldn't I take pleasure from this girl who was offering it.

My balls slapped into her chin as I drove into her mouth. She sucked and swirled her tongue as best as she could as I fucked her face. I could see her fingers inside of her bikini bottoms frantically rubbing her pussy.

It was all so erotic I knew I couldn't hold out much longer. I wanted to cum. I wanted to pump my seed directly into her throat. There was, however, something I wanted more.

I sped up, slamming myself into her face. Relishing the glug, glug, glug, sounds she was making. Chasing my climax. Finally I was just on the verge.

I yanked my cock out of her mouth, gripped it in my hand and pumped it in front of her face. Jenny grinned there on her knees and opened her mouth sticking out her tongue.

"Will you cum for me daddy?" She asked. "Please give me your cum."

I only grunted in reply. I grabbed her hair in my fist to hold her in place, finally releasing. I had fucked my wife the night before but I had plenty of spunk left in me.

I sprayed a heavy load directly into her mouth, watching the silvery goo slide across her outstretched tongue and into the throat behind. Then I aimed lower spraying again, my cum splashing across her bare tits.

I was groaning, my ass clenched, legs shaking as I climaxed. The next squirt was lighter and then I shoved my cock back into her still open mouth. Jenny began to suck, making sure to milk out my seed.

She looked perfect. Her eyes were locked on mine. I looked at her cute freckles and thought, next time I want to cum across those. My cock was halfway inside of her mouth. Cum was dribbling out of the corner of her plump lips, and slowly sliding down her breasts dripping off of one of her hard nipples.

Her hand was rubbing herself furiously and then she closed her eyes and began to moan. I could see her legs shaking as she came with my cock in her mouth. As she rode out her climax I pushed deeper into her mouth muffling the sounds.

Finally I stepped back, my softening cock flopping free of her. She looked up at me. A cum dripping, tear streaked mess. She looked like a perfect little slut.

"Thanks Daddy," she said and stood. "I better get into the water and rinse off."

She gathered up cum from her chest in her hand and lifted it to her mouth sucking it in.

"Mmmmmm, so good," she said. "I can't wait until you fill my pussy with this."

I had leaned back against the boat and laughed slightly.

"I can't wait either, Princess," I said. And I meant it.

++++++

Jenny had, after rinsing my cum off of her, re-joined Kristen on the beach and the two, after my wife woke from her nap, soaked in the sun. I, on the other hand concentrated on the boat, finishing up the scraping and then using a sanding block, smoothing it all out. I wanted it to be ready for painting first thing in the morning because I knew it would take multiple coats to get it right and I needed to leave time to dry and sand in between.

Kristen made supper: a Greek salad and grilled burgers, eaten on the deck that was attached to the cabin. It was a nice night and the sexual tension between Jenny and myself was, of course, still there like an electric current that passed between the two of us, but it was bearable. I was relaxed instead of jumpy.

I drank beer and Kristen and Jenny drank wine. We talked late into the night. A sheet of magnificent stars spread across the sky and we idly looked up at it while we chatted and joked around about everything and nothing of importance.

Eventually Kristen stood up.

"I'm going to bed," she said. "Don't stay up too late. You have a lot of painting to do tomorrow while we relax." She was teasing me lightly and I smiled.

"No," I said. "I won't be too long. One more beer. Jenny? You heading to bed?"

Jenny shook her head.

"I'll finish this wine," she said and locked eyes with me.

Kristen went in and Jenny and I were quiet, neither saying anything or moving from our spots on separate adirondack chairs. We heard my wife getting ready until finally she was settled into our bed.

Jenny stood up then and crossed the few feet between us and stood in front of me, holding her hands in front of her nervously. It was the first time she had not seems totally confident and in control through this entire time.

"Jenn..." I started then corrected myself, "Princess. We can't. Not right now."

"I know," she said quietly. "I just...I want to be held by you, daddy. Can we do that?"

I glanced at the house then nodded, opening my arms. Jenny sat on my lap, legs draped across them and leaned against me, laying her head on my shoulder. Her arms went under my armpits and held my shoulders from behind. My arms wrapped around her.

"This is nice, daddy," she said. "Thank you."

It was nice. Very nice. She smelled of the outside. Of sunscreen and a light scent of her sweat, pleasant not overpowering. It was a smell that I will always remember and if I catch something close to it I'm am instantly transported back to that time and place.

"I..." she started then stopped. "I know that...I've been, I dunno, pushing you. It's just that...I've loved you since I met you, Daddy."

This was news to me. I had had no idea. I had no idea how to respond.

"You don't need to tell me you love me. It's ok. Just be here. I'll do anything to be close to you. I'll be anything you want."

I squeezed her tight. Holding her small, perfect body against mine.

"I'll be here, princess," I promised. I did not know how. How this could possibly work. I meant it, though. I had no intention at that point of letting whatever this was between us go.

"Thank you, Daddy," she said and shifted her weight.

The girl being in my lap, her ass pressed against my cock, breasts pressed against my chest, caused the predictable reaction. I started to grow under her.

"Oh, daddy," she giggled. "what's this?"

"It's for you," I said quietly and pushed myself harder against her.

"Lucky me," she said quietly.

"Not now, though," I said, not wanting to break this embrace, not wanting to risk my wife catching us.

"I know," she said, pouting. "But soon, ok?"

"Soon," I promised. "Soon."

We sat like that for a while, hugging l, not speaking. She was rocking slightly on my cock but it was not a desperate need thing. It was just her knowing that she was providing me pleasure. My hand came up and squeezed her breast, rolling the hard nipple between my fingers. She moaned slightly and began rocking more quickly.

"That's enough," I said. "If we don't stop now we won't be able to."

"Is that so bad?" She asked rocking faster.

"Yes," I said. "Stand up, Princess."

She hesitated.

"Now, Princess," I said more firmly.

She pouted but stood.

"Good girl."

I held her cheeks in both hands. Green eyes looking up into my blue ones. I drew her in and kissed her. A slow, deep kiss, my tongue rolling against hers. After a moment. I let her go.

"Go to bed, Princess," I said.

"Yes Daddy."

++++++

The next morning I was the first to wake, feeling fine despite the drinks the night before, just thirsty. I made the coffee and went straight to the boat to put on the first coat of paint.

It took about an hour and by the time I was done I could see movement back at the cabin. I walked back up and both my wife and sister in law were awake and drinking coffee.

"First coat is done," I announced. "I'm going to go for a run while it dries."

I loved running long distances. Most days I went out for an hour before work. On the weekends I'd run further, 10-15 miles. I had competed in marathons in the past, never doing that great, at best about a four hour race, but competing never really compelled me. I just liked moving my body. Putting the miles down under my feet.

I went to my room and changed into my running shorts, wrapped my knee brace around my left knee, and old running injury that I had to be careful of, and returned to the kitchen. I didn't wear a shirt. It was already hot that morning.

When I came out Jenny had also changed it seemed. She was wearing a sports bra that squeezed her breasts tightly, forcing a sharp line of cleavage. She was also wearing very short shorts, with half her ass cheeks hanging out of them and running shoes. I had to be careful or my cock was going to rise a tent in the shorts I was wearing.

"Since when do you run?" Kristen was asking her sister.

"Oh," Jenny said. "It's been a couple months. I felt like I was getting fat and lazy so I started. I'm nowhere near a pro, like Mark. But I hope he can teach me some things today."

She looked at me with her eyes dancing.

"Oh," I said. "Maybe. Maybe I can show you something."

Kristen shook her head.

"You two are crazy," she said. "I can't imagine running in this heat. Have fun. I'll be lounging by the beach."

Running near the cabin meant running on the gravel roads in the area. The trees grew thick and close to the roads so the worst of the sun was kept off of you, and the views were usually beautiful. If it was a wet summer mosquitoes and bugs would be a problem but with the dry heat we had been having I wasn't worried about that.

Jenny and I stretched a bit before heading out. She made sure to do this in front of me, giving me a great view of her firm ass as she bent forward, the short shorts riding up and revealing more pale skin, the fabric tight against her pussy. If she was wearing any underwear I didn't see any signs of it.

We took off at a light jog, side by side not saying anything. Usually I had headphones in playing music but today I skipped that. She kept pace with me for a while then began to pull ahead. I wasn't complaining watching her ass bounce in those shorts.

"Hey," I called out. "This isn't a sprint. Steady wins this one, don't tire yourself out."

She looked over her shoulder and grinned at me.

"Oh, can't keep up, old man?" She teased. "C'mon daddy, catch me if you can!"

She broke out in a faster run and I had to laugh. I put on speed, catching up easily. Years of running and training had made it easy for me. She was breathing heavily and a film of sweat was coating both our bodies.

"I caught you," I said, talking in short bursts from being slightly shorter on breath. "What do I win?"

"You can take whatever you want, daddy," she said, looking at me. "Anytime."

I grinned and put on more speed and then veered off of the road onto a trail into the trees I knew. She scrambled to keep up. Instantly, under the leaves it was cooler, though the terrain was more treacherous. Jenny followed but I slowed down so that she wouldn't lose her footing.

The trail wound through the forest for about a mile, climbing gently the whole way. It was a strenuous workout, one I had used to challenge myself many times before. Eventually the trail widened to a clearing that was on the edge of a cliff that overlooked our lake.

You could see the cabins that surrounded it and just make out our place, tucked in the cove. I could just make out my wife in her red bathing suit on our beach.

I stopped, breathing heavily, looking out over the scene as Jenny jogged up behind me. She was more winded than me and it took her a moment to catch her breath. I handed her the bottle of water and she drank, some spilling down her chin onto her sports bra.

Then she caught the view and gasped. It was stunning. She walked to the edge and looked over it all.

"Oh," she exclaimed. "There's Kristen! If I waved would she see me?"

"Unlikely," I said. " Only if she was looking for us. She doesn't know about this place."

Jenny turned and looked at me.

"So, this place. It's ours then? Just ours?"

I smiled.

"Just ours, Princess."

I stepped towards her and pulled her sweaty body against mine and kissed her hard pushing my tongue into her mouth. She melted into my body, breast against my chest, feeling me grow hard against her.

I stepped back away from the edge, moving her with me, back towards the line of trees, backing her against one, never breaking the kiss. Finally I stepped back slightly and gripped her shoulders.

I turned her away from me and moved against her again. My cock pressed against her ass. My hands slid up her side until it met her sports bra and gripping the bottom of it pulled it up, exposing her breasts.

I was kissing her neck, tasting the salt of her sweat, licking along the side up to her jawbone. She was pushing her ass against my cock, rubbing it.

"Are you going to finally fuck me, Daddy?" She asked me, her voice a whine. "Will you finally make me your slut?"

I didn't answer but moved my hips back and shoved my shorts down my thighs, my hard cock springing free. I pushed it between her legs against her sex, the thin material of her shorts the only thing between us.

She squeezed her thighs together, and reached down, pressing the head of my cock against her clit and grinding against it. I had one hand gripping her breast, the nipple peeking out between the fingers, being squeezed. My other hand was on her hip, holding her against me.

"Please, daddy," she whined. "I need you inside of me."

I was humping myself against her and I could feel the heat of her sex through the material against my bare cock.

"Do you really want it?" I asked. "Do you need it?"

"Yes, Daddy," she gasped as I shoved hard against her. "I need it. I'll be a good girl. I'll let you do anything to me. Just fuck me please!"

I gripped her shorts and yanked them down, letting them fall to the forest floor. As I suspected she was not wearing any underwear. She reached forward and gripped the trunk of the tree in front of her.

I dipped my hips and guiding myself upwards, placed the head of my cock between the lips of her pussy, not quite penetrating her. She tried to push back, to push me inside but I moved with her, keeping just outside.

"Oh, Daddy," she moaned. "I neeeed it!"

"Tell me you are my slut," I growled in her ear.

"I'm your slut, daddy! I'm your princess slut! I need you to fill me."

With that I gripped her hip, drove my own hips forward and sank, in one motion, finally, fully inside of her.

This was the moment that we had been building to. From that first time she showed me her slutty Instagram, through all of the messages and sent photos, despite how often I protested, how guilty I had felt, this was the inevitable conclusion.

She moaned and I groaned as my cock pierced her. She was dripping wet already and despite her being oh, so tight, I slid easily into her. Her hot cunt gripped my as I slid in, molding itself to my manhood.

I felt her quiver and she moaned as I penetrated her for the first time, a small orgasm instantly overtaking her as her desire was finally fufulled.

I held myself there, buried completely in her 19 year old cunt and enjoyed the feeling of her sex clamping down on mine. As soon as she started to come down I pulled back and slammed forward again, making her groan.

"Oh fuck, Daddy," she gasped. "It's better than I imagined. You are so big! You are filling me!"

Her pussy was a revelation. I had no complaints fucking my wife but the way this tight young cunt wrapped around me was I like anything I had experienced in years.

I reached one hand around and found her hard clit, rubbing it as I fucked her from behind, using it to haul her against me. My balls swung and slapped into her with the force of my thrusts.

She was moaning as loud as she wanted now, with no need for us to hide our play.

"Oh, fuck," she said, voice shaking, "don't stop, I'm gonna cum again...ohhhhhh"

It couldn't have been long that I fucked her against that tree. I was furiously pounding into her, my need which had built up over weeks driving me on. Time seemed to disappear. She came several times, I know because she would squeal each time and I would feel her pussy clamp down on me.

Eventually though, I felt myself close to finishing. I was holding out for as long as I could, needing to make this feeling last. I could, of course, only hold out for so long.

I could feel my climax building in that space just behind my balls. I could feel my sack begin to tighten up.

"I'm close," I rasped. "I gotta pull out."

"Noooo," she whined. "It's ok. Cum in me. It's safe. I need you to cum in me."

That last begging request was enough. I slammed forward, back arched, every muscle, it felt like, tensed as I finally released into her young pussy. I groaned and gasped as I held her tight against me, cock throbbing with its release swelling then exploding spurt after spurt of hot cum into her.

She moaned as feeling my seed in her brought her to another orgasm, pussy quivering on me. She sagged against the tree, only my arms and cock buried into her holding her upright.

I let my head drop into her shoulder, gasping for breath. We were soaked in sweat, bodies sticking to onone another as we collected ourselves.

"Thank...thank you daddy," she said finally.

"You are welcome princess," I answered, leaving myself to soften inside of her, not wanting to break this connection.

"Next time, though," she asked, "Will you fuck me in in my ass, daddy? I've been saving that for you."

I grinned against her back.

"I think I can do that," I said.
