little sis in lockdown

I have been staying at my parents' house since I lost my bartending job after the restaurant I worked at shut down for good two months ago. I've been pretty lethargic, sleeping most of the day and hanging out in a tiny little bedroom. I'm 26 and accustomed to having my own space. Suddenly having to share space with my mom, dad, and little sister was a big readjustment. To make matters worse, my sister Ava moved into my bedroom when I left the house five years ago, so I am stuck in her old one.

Ava just turned 18, and she's starting her senior year of high school. She has been home all summer just reading books and messing around on her phone. We keep to ourselves as much as we can in a 3 bedroom house, but end up spending quite a bit of time together. She is about 5'4" and has an athletic body, thanks to years of gymnastics.

Growing up, we weren't very close because of the age difference. Even though she's 18, I still look at her as my baby sister. She is a smart girl and does really well in school. She has a couple close girl friends, but she doesn't run around with the popular social circle of football players, cheerleaders and such. She isn't awkward, but she's relatively shy, and the party crowd doesn't really appeal to her.

We've spent a good amount of time discussing all the social movements, economic turmoil, and societal upheaval that has taken over the news cycle this summer. It's been kind of nice getting to know her as an adult. Especially with how bored I've been lately, having someone pleasant to talk to is comforting. She's not the little girl I always picture her as anymore. She's a smart, capable, and nice looking young woman. Her breasts aren't huge, but they are nice and perky, which seems to be the case with most gymnasts. She has a great ass, though. I was caught off guard the first time I noticed her curvy backside shaped by years in the gym. She wears leggings around the house most of the time, highlighting her best asset. She has had a couple boyfriends, but nothing serious. Being the homebody she is, I don't think she was too concerned with dating at the moment.

Last weekend, I needed to wash my favorite pair of sweats after spilling some wine on them. I only had a couple other things to throw in the load with them, so I asked Ava if she had any laundry she wanted to toss in with mine. She told me she did a load earlier that afternoon so I emptied my basket into the machine and adjusted the dial. Just before I closed the lid I heard her call from down the hallway.

"Hold on a second, please! I might as well wash this stuff," she said as i walked back towards her bedroom.

We met in the hallway and I saw she had changed into some lightweight purple pajama shorts and an old t-shirt. Her hair was braided in pigtails today and she looked like the shy, innocent girl I had always known. She thanked me as I reached out and took the clothes she wore earlier from her. As she turned around I noticed her shorts looked a size too small. They hugged her ample bum, and just barely covered the bottom of her cheeks.

I pulled my eyes away from her perfect rear end and walked back to the bathroom with the washing machine and dryer. In my hands were the yoga pants and halter top she wore earlier. As I tossed them in the washer, a pair of light purple panties fell on the floor. I reached down and picked up a lace trimmed thong. I was surprised my little sister wore sexy underwear. They weren't see through or anything, but they certainly weren't the cotton briefs I would have expected.

I pictured her wearing them and I felt my dick react. I brought them to my nose and smelled the crotch. I knew my sister was a cute girl, but a switch had just been flipped. I closed the bathroom door and closed my eyes as I slid my pants down a little and grabbed my dick. I stroked myself while sniffing Ava's panties. After only a minute I was about to explode, so I pulled the panties from my face and came inside the crotch. I tossed them in with the rest of it and started the machine.

I was thinking about her tight young body for the next couple hours as the laundry went through its cycle. When it was finished, I brought it all back to my room to fold. I placed the little thong on top of her pile and carried it to her room. Her door was cracked and I gently knocked and pushed the door open. She was lying down on her bed reading, but jumped up and took her clothes from me and put the pile on top of her dresser.

I asked her what she was reading as she got back in bed and looked her phone. She was now leaning against the headboard with her knees bent and hanging off to either side. I could clearly see the outline of her pussy lips through the thin material of her shorts. I said "goodnight," and went back to my room for the night.

The next morning I went in to wake her up for breakfast. I said her name a couple times, and she just rolled from her side to her back but didn't open her eyes. I tapped her shoulder, and she sighed but still kept them closed. Finally, I just grabbed the bedsheet covering her and pulled it off while she moaned in protest. I was shocked to see her shorts in a ball on the bed and her uncovered pussy in plain view. She didn't even move, so I assumed she didn't remember she had taken her shorts off. I snapped a picture of her for later, then I quickly grabbed the panties I jacked off into the day before. I walked back to the bed and tossed them so they landed on her lower belly. "Might wanna cover yourself up, sis," I told her and walked out of the room.

My cock was rock hard as I went back to my room and closed the door. Why was she not wearing her shorts? My imagination took over and I pictured her sliding her fingers in and out of that tight young pussy. I imagined her looking into my eyes as she played with herself, showing off for her big brother. I opened my phone and zoomed in on her plump pussy, covered only by a neatly trimmed patch of light brown pubic hair. I imagined I was in between her legs, licking up and down her gash as she said my name. I grabbed a tissue from my nightstand and came into it. I stood up to put my pants back on and walked out my room and down the stairs.

My parents were both on their way out the door for work, and I sat down alone at the kitchen table. I ate my bowl of cereal, looked through the news on my phone, then went upstairs to take a shower. I heard knocking at the door and my sister's voice from the hallway.

"How long will you be? I'm running late. I need to brush my teeth," she asked.

"I'll be out in ten minutes, then it's all you," I shouted back.

"I don't have ten minutes. I can't be late on the first day," she argued back.

"Then come brush your teeth. I tried to wake you up a while ago," I said.

She walked in and went to the sink. I could see through the clear shower curtain, but it was pretty blurry. She was wearing a skirt and spaghetti strap shirt, and I wondered if she was wearing those sexy panties I tossed at her earlier that morning. I pictured guys at school seeing up her skirt as she sat in class. I felt my cock getting hard as I lathered myself.

"Was it warm in your room last night?" I asked her.

"What do you mean?" came her reply.

"I mean you weren't wearing any shorts when I woke you up," I said smiling.

"Oh my God! I was so out of it this morning. You saw me naked?"

She sounded honestly surprised to hear this information.

"I didn't see your boobs," I told her, thoroughly enjoying myself.

"But, you saw my...?"

"I saw your pussy," I interrupted her.

My cock was completely hard. I had never said anything like that to her before. She continued brushing her teeth in silence. The tension in the room was palpable. I was enjoying it, but I decided to try to lighten the mood and said, "No big deal. I can handle seeing a naked girl."

"Well maybe I don't want my brother looking at my vagina," she shot back.

"Next time don't take your shorts off then," I called after her as she walked out of the bathroom.

I jacked myself to completion in the shower, got out and dried off. Ava had already left for school, and I couldn't stop thinking about our bathroom conversation. I was now alone in my house, and didn't bother putting any clothes on. I walked into my sister's room and opened up the top drawer of her dresser. Her bras and panties were lined up and folded neatly. I grabbed a bra and looked at the cup size. 34B. I tried to picture what her naked breasts looked like. I wondered how big her nipples were. She had some plain cotton panties and a few sexy looking ones. I grabbed one of the lacy ones and brought it up to my face. I was so horny. I went and grabbed my phone and sent a text to Ava.

"Sorry about earlier. I guess I would feel weird if I were you, too."

She replied quickly, "It's fine I guess. But it's weird knowing you've seen me naked."

"I have an idea," I wrote back.

"What's that?" She asked.

"If you see me naked are we even then?" I sent her.

"Haha. As if you'd show me," she said.

I took a selfie on my bed. My dick was hard and I held it in my hand My face and penis were clearly visible in the picture. My cock was about 7 inches hard usually, but it had to have been a half inch longer in this picture. I felt so dirty. I sent it to her. "There you go."

"Oh my god!" she replied. "Why do you have a boner?"

"I thought it would be rude if I wasn't hard after looking at your pussy," I said.

"Well, thanks, I guess. This is weird," she texted back.

"Send me a selfie? I barely even saw you earlier," I pushed my luck.

A few minutes later I received a picture of her sitting on the toilet with her legs spread. She had her panties pulled to the side and her inner folds were clearly visible. Her slit looked wet and I grabbed my cock. Her face was in the picture, too. She was sticking her tongue out at me.

"Looks delicious. Can I taste after school?" I texted back.

"You want to eat your little sister out, you freak?!" came her reply.

"Come to my room after school and see!" I said.I lay in bed going back and forth between the two pictures I had of my little sister, stroking myself but trying not to climax. I got bold and went to my bedroom door and opened it, then got completely naked and went back to what I was doing.

At 3:01 PM I heard the front door unlock. It was a half hour before she usually came home, but I didn't think much of it, and kept playing with my cock. It was the moment of truth. Was she actually going to let me lick her pussy? That remained to be seen, but I was gonna show her my cock either way. My heart was pounding at least as hard as my hand was pounding my cock. I heard footsteps walking up the stairs. My bedroom door was wide open, and my eyes were almost completely closed, but my right eye squinted slightly open to see her reaction when she saw me.

What happened next almost made my head explode. I was engaged in the kinkiest, most forbidden act of my life. I had been trying to hook up with my little sister all day, and wasn't expecting anything to happen that would minimize the craziness of that, but it did. My mom came around the corner of the hallway, and my eyes immediately opened wide as she gasped and covered her mouth with her hand. I tried to cover myself up, but she got a clear look at what was going on. She may not have seen the pictures I had open on my phone, but there's no way she didn't see the pair of Ava's panties draped over my thigh while i held my boner in my hand.

She turned and ran down the stairs as I quickly threw some sweatpants and a t-shirt on and chased after her.

"Mom, I'm sorry. I didn't expect you home," I pleaded in absolute terror.

She looked at me without saying anything for a long moment, her face flushed red and mouth slightly agape. After an agonizing wait, she whispered, "It's a natural thing, but what if Ava had seen you like that? Did you even think about that?"

I stuttered back, "I thought I had the house to myself for another half hour. Of course I didn't forget about Ava, mom."

"And using her panties? She would feel so violated. All the porn in the world on your phone and you take your sister's underwear. They aren't even lingerie! Where are they?

I pulled the cotton briefs from my pocket and handed them to my mom. She walked up the stairs and I followed her as she went into Ava's room and to her dresser to put them away. As she folded them she suddenly brought them to her nose and looked at me. "Where did you get these?"

"The hamper," I replied meekly.

"I don't even know what to say to you, she huffed and walked to the dirty clothes to discard the panties. In one of the hampers next to it was a pair of her own panties, a lacy thong much more skimpy than the panties I had of Ava's. "At least use something sexy to get yourself off instead of your sister's underwear." She flicked them at me and I caught them and brought them to my face and smelled my mom's panties right in front of her.

"I'm so sorry. Please don't tell dad" was all I could mutter.

"Tell dad you like to sniff his wife's and daughter's used panties? Good call. He would completely explode." She looked down and saw my boner pushing prominently from my sweatpants and said, "take care of yourself before Ava gets home."

"With this?" I asked, holding out her thong.

She reached underneath her knee length skirt, pulled down a black lace g string with a partially transparent crotch and dropped it on the floor. "Use whatever you want, but this stays between us. You're welcome, by the way. Your sister would be disgusted and your dad would kill you."

"So you're not disgusted?" I slid my hand in my pants and sniffed her underwear. She gasped again, but didn't say anything.

I stroked myself under my pants and stared at her. Her blouse showed a little cleavage, and I was staring hard. I looked in her eyes and asked shamefully, "Can I see your boobs?"

She mumbled under her breath and unbuttoned her shirt, unclasped the bra from the front and pulled it aside, revealing her breasts. I started jerking faster, letting my pants slip down my thighs before coming before I could warn her, covering her skirt and torso, even getting some spunk on her exposed tits. She watched as I stroked the last bits of semen out on the floor, pulled her shirt and bra over her head to put in the hamper, then walked by me and said "Clean yourself up," before going to her room. She left the bedroom door open and went into her bathroom. I took a shower, then put clothes on and noticed her soiled shirt and bra on top of the hamper. I decided to ask her what she wanted to do with them and went into her room. I knocked on the bathroom door and opened it. She was in the shower as I asked her what to do, and opened the curtain to answer. Her full bush was on display now as well as her tits. "Throw it on the floor. I'll take care of it."

I just stared at her crotch. I could see her slit through her pubic hair, and she rubbed her soapy hand on it, saying "get a good look?"

I hobbled out of her room once again rocking a huge erection. She hadn't even gotten mad at me, and I got to see my mom fully naked just minutes after she saw my cock. I went back to my room and shut the door this time before jacking off again. I heard my sister come into the house. I crept out of my room and met her as she got to her room. I quietly followed her inside and told her the basics of what had happened; mom had caught me masturbating and that I accidentally saw her naked in the shower. Ava decided we should just go ask her what was for dinner and pretend there was no drama between the two of us. I reluctantly agreed, and we walked past her partially closed bedroom, Ava leading the way. The carpet made our footsteps almost inaudible, and my mom didn't even notice us enter as she lay on her bed, her top covered by a white towel as she toyed her hairy pussy with a small pink vibrator, moaning quietly. Ava turned to leave, but I stopped her quietly and pulled my phone out. I recorded my mom masturbating for about a minute as I held Ava in front of me, poking her in the back with my throbbing cock.

My mom rolled on her side and began fingering her pussy from behind. I zoomed in for a close up then grabbed Ava lightly on her navel and pulled her with me out of the room. My room was further down the hall, and we tip toed inside, shut the door, and I grabbed her face and kissed her on the lips. I snatched my phone from my pocket and we watched the video, which actually was of pretty good quality, my mom's wet cunt shown clearly. I gently pushed Ava back so she lay on the bed with her feet hanging over the edge. I pushed her skirt up and buried my face in her panty covered mound. She was already soaking wet, and I pulled her crotch of her panties to the side and tongued her clit as I slid a finger inside her pussy. She huffed quietly and I pulled her skirt and panties off, leaving her legs spread open, her dark pink labia protruding from her little cunt. She didn't have a bush like my mom, but she wasn't completely shaven. I grabbed my phone and used my back stand to position it on the dresser by the bed and went back to eating her out. She had her first orgasm suddenly, wrapping her legs around my head as she let out a soft squeal and my face was drenched with her juices. I licked her clit for another few seconds then stood up and dropped my pants, my cock harder than it had ever been. I grabbed the phone and held it as I slowly penetrated her. I panned up to her face as I buried myself inside her pussy. I turned the camera to my own face then resituated it on the dresser. I lay on my back and she crawled on top as she took off her top and lowered herself on my cock. I pulled her face to mine and we kissed passionately as I guided her up and down, careful not to hurt her.

She jerked her head to the door suddenly as my mom knocked on my door. "Have you seen Ava? Her book bag is here, but I can't find her."

"Maybe she went for a walk," I said as calmly as possible as my sister's pussy pulsated on my cock.

"Get yourself ready for dinner. And I'd like my panties back before dad gets home. Not a word," she said.

Ava looked at me with complete shock, and I covered her mouth with my hand and gently flipped her over, my finger pushing softly into her bum briefly before lying her down and pounding her aggressively until I was about to come. I pulled out right before I exploded but she whispered in my ear, "come inside me."

I drove back inside and blew my load inside as she grunted and panted in ecstasy. Another knock came from my door.

"Enough porn, okay? Your dad and sister could be home any minute."

I pumped her for another minute as I sucked her neck, leaving a pretty obvious hickey. We fumbled for our clothes, and I made sure the coast was clear before she scampered to her room. I watched both videos again and hatched a plan to get inside my mom's pussy next. All I knew for sure was dinner would be interesting.At dinner my mom's eyes were fixated on my sister's neck. My dad was going on and on about something that happened at his work, but I have no idea what it was because of the tense electricity in the dining room as my mom, sister, and I sat quietly, trying to act normal. Ava was brushing her foot against mine discreetly under the table, and I got bold and found my mom's bare foot and did the same to her a couple times as she just kept staring at Ava's hickey, not even acknowledging the one-sided game of footsie she and I played. I was enjoying every minute of it.

Finally, my dad looked up after probably noticing that we didn't seem to be paying any attention to him and finally noticed the dark red mark on my little sister's neck. He started out with a sympathetic tone as he patronized his 18 year old daughter.

"Honey, what did you do to your..."

He paused for a moment, then continued in a much different tone of voice. It hadn't even crossed his mind at first, but the hickey was so undeniable even he couldn't pretend it was anything else after looking at it a couple seconds.

"Wait. Why the hell do you have a hickey on your neck?" he barked sternly.

"I would love to know the answer to that as well," my mom chimed in.

"Not that it's any of your business, but I hung out with a boy after school. He got a little carried away when he kissed me I guess."

"Who is this guy?" My dad snapped back. "And since when have you been hooking up with boys after school?"

"He's older. It doesn't matter anyways. I think there is another woman. He told me a story that sounded innocent, but I think he left out some important information. I don't know yet," came my sister's retort.

I sneakily placed my hand on her leg under the cover of the table, and played with the hemline of her shorts as I entered the conversation.

"Sounds like a lucky guy. But if I were you I would just ask him what's up instead of assuming the worst. It seems like he's pretty into you, judging by the evidence on your neck."

I was playing with fire.

"You're quite the attraction today. Your brother was wondering why you weren't home this afternoon, too. Weren't you?" She glanced at me.

I slid my hand further up Ava's thigh and She wasn't wearing any panties. I slid a finger inside. "I ended up getting ahold of her anyways," I said with a little smirk on my face.

Ava inhaled sharply as I flicked her clit, and my dad looked over at her. "Last I knew, you didn't even care about boys. What happened to my sweet, innocent little girl?"

"I'm still your innocent little girl, dad."

My dad sighed and stood up to take his plate back to the kitchen, and mom followed behind. My finger was still playing with Ava's pussy under the table, and the tent in my pants prevented me from getting up at the moment. She reached down and pulled my hand away to get up and join my parents in the den where they were watching one of their boring network TV comedies. I tucked my cock up under my waist band, got up to put my plate in the sink and went to my room.

After an hour or so I went out to see what was on TV. My mom had started doing dishes in the kitchen, but Ava and my dad were watching Seinfeld reruns, and I decided to join them. I sat in the recliner next to my dad. Ava was on the lying on the couch on the other side of my dad with her eyes closed. One of her knees was bent, hanging off the side of the couch, while her other leg was resting flat on top of her ankle.

I looked over at my dad and he wasn't paying attention to the TV. Shortly after I sat down he got up and walked out of the room without saying a word, so I walked over to grab the remote from his chair. I sat down in his spot and looked at Ava. Her uncovered pussy lips were in plain view! She opened her eyes, smiled at me, and put pulled her shorts back to cover herself up, before getting up and going to her room. She had been giving dad a show on purpose. I was immediately jealous and turned on at the same time.

I looked back in the kitchen, and mom was still cleaning up after dinner. She was wearing snug leggings that showed off her amble ass nicely, with a thin sweater on top. I opened my phone to the video of her fingering herself and held it open looking back and forth between it and her in the kitchen. After a minute or two I got up and walked in the kitchen. She was bent over the dishwasher, trying to make room to fit the last two plates in. I walked behind her and boldly grabbed her ass and poked my middle finger against her pussy, feeling it push between the puffy folds. She jerked around and slapped me with her mouth wide open.

"What the fuck do you think you're doing?"

The tent in my pants was bulging, and I made no attempt to hide it as I moved towards her, pinning her lightly between myself and the counter, my cock pressing into her upper abdomen. She was still staring at me with her mouth partly open in shock. I lightly grabbed her chin and planted a kiss on her mouth, nibbling gently on her bottom lip before pulling back.

"What I'm doing is apparently what dad can't," I replied. "I'm going to take care of you way better than your little pink toy ever could."

She gasped.

"How do you know—" but her voice stopped suddenly as I slid my hand down the front of her pants and felt her trimmed bush and poked my finger inside her cunt.

I leaned in close to the side of her face as I pushed another finger inside her. "I watched you playing with your toy and fingering yourself. But I want the real thing." I sucked on her neck. "And I think you do too."

She pushed me away from her. "Stop! You're going to leave a hickey." She trailed off as she finished, and I could tell she was reminded of my sister's hickey. "Wait a minute," she said. "You didn't hook up with Ava, did you?"

I didn't bother answering her. I was already on my knees, pulling her leggings and panties down her thighs as she tried holding them up with one hand. Her sweater didn't hang very low so her entire sex was on display right before my eyes. In our kitchen. With my sister twenty feet away in her room. With my dad somewhere in the house. The intensity of looking at my mom's beautiful trimmed pussy, coupled with the possibility of being caught by another family member had me hornier than I had ever thought possible. I dove in and began licking her clit while I grabbed her calf of her left leg and moved it off to the side as far as her leggings wrapped around her ankles would allow. Her pussy was soaking wet, and I slid two fingers inside her easily as I nibbled at her clit.

She had one hand covering her mouth to muffle her moaning and the other one pushing my head away, or at least pretending to, in protest. I found my way up her shirt and under her bra and squeezed at her breasts as I drove my tongue inside her. I could feel her attempted reluctance slipping away as she grabbed a handful of my hair and tugged it. Not the way you tug to pull away. She was tugging my hair lost in pleasure as I ate her out.

I grabbed the leggings that were holding her feet together and pulled them off her left ankle as I stood up, lifting her onto the counter as I did so. Her shirt was above her right breast, but covering the other one, her dark nipple rock hard and asking to be pinched. Played with. Sucked. I resisted the temptation to lick the very breast I was fed from as a baby, and focused my attention to the more urgent matter at hand.

What would have seemed inconceivable, impossible, and just insane a couple days ago was no longer any of those things. My mother was on the counter in front of me, her plump pussy lips wide open with the darker purple inner folds protruding out like a flower in bloom. I could still hear the laugh track from the den accompanying the same episode of Seinfeld I had been watching with my dad and sister less than twenty minutes earlier. This wasn't my ultimate fantasy. No. This was more. The epitome of what my ultimate fantasy could be if I was all-knowing. I wasn't going to let it slip away.

Instead, I unbuttoned my pants, methodically but quickly, while maintaining eye contact with mom. I dropped my pants and boxers to my knees, and my cock flung into view in all its glory. My mom finally broke eye contact with me as she saw my huge erection right in front of her. She looked back up and opened her mouth to say something, but I put a finger gently on her lips while I guided my dick to her opening and flicked it up and down her soaking wet slit. Whatever last minute thoughts she may have been having when she was trying to speak disappeared as she took my finger inside her mouth.

I pushed myself inside her awaiting cunt, and pulled my hand from her mouth to grab her ass from behind and pull her closer to the edge of the counter as I drove all the way inside her and pumped my cock in and out. I took it all in. The way her tits bounced, with just the one out in the open, the flushness of her face as she mustered all the energy she had not to scream, the sound her wetness made as my cock slid in and out of her pussy. The scent. Oh that scent. It couldn't have been more than two minutes that I was fucking her before I felt myself on the verge of exploding. She had already orgasmed as I ate her out, but seemed to be near climax once again.

I picked her up off the counter and held her with both hands under her ass as she leaned back, supporting herself with a hand against the cabinet. One of my fingers inadvertently touched her ass hole for the first time, and I applied some pressure while I kept fucking her. The motion of her bucking on my cock led to my finger sliding into her ass to the second knuckle, and I felt her begin to buckle again. I leaned her back onto the counter top, spread her legs completely apart and pulled her ass forward so she was barely on the counter. I pinched her exposed nipple as I pecked her on the lips again and sucked lightly on her neck once more. All the implications of the hickey situation were clearly in my mind, as I pulled away. "I suppose I shouldn't cause another awkward dinner conversation," I said quietly, before lowering my face to her gaping sex.

"You did have sex with your sister, didn't you?"

Her tone of voice sounded accusatory, as if she was scolding me for something unspeakable. She would have had a good point usually, but as I buried my nose in her wide open pussy and licked my tongue down her slit and onto her ass hole, the whole sentiment of her being upset with me for fucking my little sister was pretty laughable.

She gasped as I pushed my tongue in her ass and brought her hand down and started fingering her clit feverishly. I didn't linger too long on her ass. Just long enough to etch it in my memory bank forever and to take her to the edge. I wanted her to leave this situation needing more from me. But right now I had to take care of my own needs. I stood up, replacing my tongue with my thumb in her ass and once again put my dick inside her puffy cunt. I pumped much harder than before this time, and as I felt her pussy clinching around my cock in orgasm I whispered to her.

"Ask me for it, mom"

"Ask what?" She huffed between muffled breaths.

"Ask me to come inside you before someone walks in on us." I kept pumping, but intentionally clanked the two remaining plates she hadn't fit in the dishwasher together, to remind her how a loud noise could blow this situation out of control.

"Just do it. Hurry!"

"Do what?" I asked again.

"Come inside me. Please."

"That's better..."

"Take me. Play with my ass. Do whatever you want, baby. Please just hurry! Come inside your mom' pussy. Oh my god! Just—"

Her begging stopped short as I exploded in ropes. I kept driving into her, the mess of both mine and her ejaculate making squishy noises as I pounded her against the counter. I slowed down and came to a stop as she looked at me with something between horror and uncontrollable lust in her eyes. I leaned down and kissed her, this time taking the time to accept her returning it. My tongue slipped inside her mouth and met hers as I maintained pressure against her, my cock still penetrating her fully.

The moment of passion, eroticism, love, confusion...whatever you want to call it was interrupted in an instant, however, as the buzzer to the dryer buzzed from the laundry room, and a bedroom door upstairs slammed shut. As we heard the unmistakable sound of footsteps coming down the stairs I pulled away from her and pulled my pants up as she frantically got her leg inside her pants and pulled them up and pulled her sweater and bra down. She grabbed the plates to put in the dishwasher just as my dad came around the corner, holding a laundry basket. He liked folding his laundry in front of the television, and didn't notice moms disheveled hair and red flushed face as he walked by.

I looked back at my mom and at her ankles there was a little bunch in her pants. She apparently hadn't slipped her foot into the panties when she pulled her pants back up. I motioned for her to put her leg up, and after making sure my dad wasn't looking she did so. I pulled the white thong out of the bottom of her leg hole and held it to my nose for a second. Ah. That scent. The one I would never forget. They were only slightly damp, as I'd gotten them off her before most of our encounter happened. I walked into the den where my dad was folding jeans and sweaters like usual. I said to him, "Did these fall out of your basket?" and held mom's panties up. He only washed his own clothes, so I was just being kinky for my mom's sake asking him that, but he acted a little confused.

"They may have, actually. Someone else must have thrown their dirty clothes in with mine."

That's when I noticed about a half dozen brightly colored skimpy panties in his pile of neutral colored garments. Ava came into the den right in the middle of this and walked over as my dad was confused and trying to fold a particular pink thong that was too small to even fold. Ava leaned down and kissed my dad on the cheek. "Thanks, Daddy!"

She was wearing one of my dad's old t shirt baseball jerseys from when he coached me years before, and it hung halfway down her thighs. Acting as if it was no big deal, she pulled her panties off and put on the pink ones, tossing the worn blue cotton ones on the couch by my dad. She got back in the position she was in earlier when she was showing off for him and began playing with her phone. I walked over and picked up her dirty underwear and said I'd put it in the hamper. My dad kept folding laundry, trying to keep his eyes off his daughter, whose shirt had ridden up high enough to expose her little thong just barely.

As I walked up the stairs I sniffed both my mom's and sister's panties and thought back to banging my mom just minutes earlier, but was envious and jealous of whatever my sister was up to. I wanted her all to myself, but she was playing a game I wasn't prepared for. Just as I got upstairs to stash both panties under my pillow for later, my phone vibrated. It was a text from my mom.

"Do my panties smell as good as your sister's?"

She added a tongue out silly emoji, but I knew she wasn't completely kidding. She was likely just as confused and jealous or territorial or whatever the word is to describe the familial lust as I was. And even though I had certainly implied I gave Ava the hickey, she didn't know for sure, and she definitely didn't know the extent of it. I played along, but made a point to keep things as ambiguous as possible.

"Ava's smell like a curious but innocent young girl. Yours smell like a woman moist because she wants to suck a cock. I'll give you my answer in like ten minutes..." I added an emoji, too. The face with the mouth wide open in shock, but she obviously understood my implication was a little different.

Less than a minute later, there was a light knock at my door and my mom crept right in. I was already in my bed naked but for a t-shirt. She came to my bed, crawled on and gave me the best blowjob I've ever had, not hesitating to swallow the rather small amount of jizz I still had left to give after exploding in her earlier. I got the whole thing recorded on my phone, too. All three minutes of it. I had previously thought it was impossible for me to come from just a blowjob. It had always been a precursor to sex, a lubrication method, an appreciated but overrated act of submission/cooperation from a girl to heighten the mood. Not this time. I'm kind of relieved I was almost spent of semen or else I'd have been afraid of choking her the way she took at least three quarters of my length into her throat with enthusiasm I'd never even seen in porn. She saw my phone filming her and it didn't stop her one bit. I changed the camera to the front to show my face reacting to it, but mostly focused the video on her. At times she looked right into the camera, and there was absolutely no doubt to anyone who ever saw the video that she was sucking her son's cock.

After I came in her mouth she looked at me and just stared for a few moments before breaking the uncomfortable silence.

"I wonder if Ava returned the favor to the boy who gave her that hickey." She picked up both the panties I had taken that were lying on my bed and sniffed her own, then Ava's. "Nah. I don't think so. Her panties smell like a sweet young girl who doesn't need her horny brother taking advantage of her. Your mom can take care of herself. And she can take care of you. But leave your sister out of it. Please."

"I love you, mom."

"Love you, too. And don't even think about posting that video on the internet!"

She walked to the door, but turned around at the last second.

"But if you do, blur my face out. And send me the link."

She went to her room and closed the door. I snuck quietly down the stairs and listened from the kitchen to see if I could hear my sister and dad in the den. She was trying to convince him to give her a back rub and he was nervously resisting. Then I heard her say "Here. I'll make it easy, daddy."

"Ava, what are you doing?" I heard my dad sigh.

"I'm really sore. Just a few minutes..."

"Just a couple minutes" my dad said quietly.

After about thirty seconds Ava said "Ugh. This keeps getting in the way," followed by my dad saying "Ahh no. Don't do — that..."

"That's way better," she giggled.

I had to know what was going on, so I quietly snuck to where I could look in the room. There on the couch Ava was lying on her stomach across my dad's lap. She had pulled an arm out of the shirt, leaving her back naked, which must have been what my dad had just tried unsuccessfully to resist to. The pink thong that showed off nearly her entire ass was lit up by the lamp beside the couch, and my dad was gingerly rubbing her back. She was guiding him to her lower back, but he was being careful not to touch near her underwear. I stood there watching from the dark until my dad said "time's up."

Ava fake whined like a child, but then rolled over off my dad's lap, her shirt still pulled over her shoulder.

"Whoops" she giggled as her tits were now fully on display. She slowly pulled her shirt back on, kissed my dad on the forehead, and walked out of the room and back upstairs. I waited a minute, poured a glass of water, and walked into the den, where my dad sat with a freshly folded towel on his lap, obviously covering the boner he had for his daughter.

What the hell is happening to my family?
