There we were, sitting naked in our parents’ hot tub. My sister Gen was on my lap with my cock inside her pussy as far as it would go. My girlfriend Lisa was leaning on the side of the tub completely nude with my sister’s boyfriend’s cock deep inside her. All four of us were staring at our porch by the house where Gens and my parents were currently fucking. They were gone earlier and should have been out all night but clearly had come home early and walked in on us. As the four of us were shocked in the moment, Gen had started to grind into my cock again, clearly a sign that she was turned on by the scene. Other than that, none of us moved.
We were frozen there for 20 to 30 more seconds until we heard and watched my dad cum into our mom’s pussy. Once they had finished you could see the look of shame and regret wash over their faces. They both pulled their pants up, turned and walked quickly into the house. Still, no one moved. We heard their bedroom door close and the lights in the house turn off.
Slowly Gen pulled off of my cock and sat back in her seat, Tod pulled out of my girlfriend and did the same. The four of us sitting naked across from each other speechless. Tod spoke first, that was fucking hot! Then Lisa, which part? Gen fucking her brother, you fucking me, or Gen and Johns parents fucking while watching us? Tods only reply was, YES. We all chuckled at his response. It’s funny to think that I almost lost sight of the fact that someone else had just fucked my girlfriend in front of me or that I had just fucked my sister, all because of the distraction of our parents showing up.
The four of us got out of the tub, retrieved are suits from the grass and put them back on. We grabbed our towels, dried off and headed into the house. Lisa and I went to my room and Gen and Tod went to hers. Lisa and I spoke for a couple minutes and we got a text from Gen saying, Tod was going to head out and they thought Lisa should do the same. Lisa and I agreed and the two of them left and called it a night. Our parents were still locked up in their bedroom, obviously ashamed of what they had just done. I took a shower and changed into some gym shorts.
When I was getting dressed I heard Gen do the same. Several minutes after her showering I heard her bedroom door close as she retreated back to get dressed. I got several texts from Lisa, the first asking if our parents had spoken to them yet followed by how hot the night was. I agreed and told her I had an amazing time. She responded that she was glad I wasn’t angry and that everyone seemed to enjoy it. She confessed that several times in the hot tub she was worried that I might get jealous or regret what we were all doing. I told her I was worried about the same and that once we were done that she might think what happened with Gen and I was disgusting but I was glad that it only turned her on more. We said goodnight and I laid down.
That’s when I got a text from Gen in the room next door asking me to come over. I got out of bed and cracked my bedroom door open and looked down the hallway to my parents room. The door was still closed and no sign of life. I went to my sister’s door and opened it quietly, walked in and slowly closed it behind me. Gen was sitting on her bed sitting with her legs crisscrossed. She was wearing a white t shirt with no bra and a pair of shorts. The way she was sitting I could see down her shorts to her panties slightly exposed and her nipples where noticeably hard as well. She caught me looking and said out of habit of being a sister, quit looking pervert! She cut herself off and started to giggle from the irony and said sorry that was autopilot, I wasn’t even thinking that you just fucked me a couple hours ago. I chuckled with her.
Gen shifted slightly and asked, what the fuck was that?? I looked at her with a puzzled look on my face and responded, what the hot tub? She then said, no not that, I’m talking about mom and dad. She continued on saying, no the hot tub stuff was super-hot. I’ve always wanted to see Tod with another girl and I’ve always found messing around in front of people s turn on. Honestly between those two things I wasn’t even focusing on the fact that it was involving my brother. With a look of relief I said, oh good, I was worried that you’d regret it after we all came down from the fun high. She then said, hell no, that’s something I’ll never forgot nor do I want to. I’m talking about what the hell was with dad and mom fucking while watching us all. I would assume they would just yell at all of us if they caught us, but instead fucking while watching, that’s messed up. I said well, you and I have a high sex drive clearly, where do you think we got that from. And you just admitted that you got lost in the fun of the moment and wasn’t focusing on the fact that I was your brother. Maybe it’s something along those lines? Gen stopped and thought about it for a while and admitted that maybe I was right. We decided to call it a night and see what would come of it in the morning. Just before I left her room I turned and said, I didn’t get a great look when we were outside, is it weird if I ask to see your tits again. Gen just smiled a wicked smile while pulling up her shirt to flash me her perfect perky tits. Smiling as well, I turned and left her room.
The next morning was very weird. I left my room and headed to the kitchen where I found my mom making breakfast, my dad drinking coffee at the counter and my sister sitting at the kitchen table. I sat down next to her and mouthed, anything? She mouthed back to me the word no. Our mom and dad were acting like nothing had happened at all. They were going to completely erase last night from our collective memory and move on. I sat there running everything through my head and then noticed my mom’s tits swaying under her shirt while she was mixing up pancakes. What the hell is wrong with me? I have an amazing looking girlfriend that fucks like a pro, just fucked my sister last night and now I’m checking out my mom. As I diverted my eyes away from my mom I saw my dad had caught me looking, I quickly looked down at the table, the only safe place.
That was the only interesting thing that happened all morning, all day in fact. Once again I was lying in bed texting Lisa, telling her about how my parents were handling the situation. We both agreed it was the best thing that could have happened and sure beat getting yelled at. The next couple of day’s things returned to normal in the house and with the six of us. Everyone had successfully acted like that night never happened and I also hadn’t seen Gen inappropriately since she flashed me leaving her room that night. It had been almost a week when our parents told us that they were heading out for the night and won’t be home until almost midnight.
I was in my room and as soon as their car left the driveway I heard Gen opening my bedroom door. She said that Tod was coming over to hang out and asked if Lisa was. I asked her why he cared and she said, what do you think, he has a crush on her now as she laughed. I told her I’d give her a call. As she left I was already dialing Lisa and asked her to come over and hang out. She said she would leave in 30 minutes.
Tod arrived first and I could hear both of them hanging out in the living room. Lisa took a little longer but finally strolled into my bedroom. She had taken a little longer because she was sneaking liquor from her parents’ garage. We went out into the living room and joined Gen and Tod where we all started to drink. We threw on a TV show in the background and someone brought up last week. We all had not spoken about it since that night, only about our parents and if they had freaked out on us yet. We all collectively agreed how hot the night was and wished that our parents wouldn’t have busted us. As we all continued drinking Lisa said, at least we didn’t notice them until we all had our orgasm. Tod then said, I wonder how long they had been watching us for and btw John, your mom is hot which got a laugh from everyone. I responded you’re already fucking my sister and have fucked my girlfriend, now you want my mom too?
You could tell the conversation was turning again and heating up. Everyone was getting buzzed from the liquor and turned on from talking about fucking. That’s when I almost missed it. From where I was sitting if I looked pass Tod over his shoulder I could see the window in the kitchen. It was already dark outside but out of the very bottom corner I could see someone peeking into the window. It was my dad!! I stayed calm, didn’t make any sudden movements but started to scan the other windows I could see, sure enough two windows over I could see my mom just in the corner. I kept talking in the conversation but took my phone out. I wrote a text to Gen that said, don’t freak out but mom and dad are spying on us through the window. Several seconds later Gen looked down at her phone. I watched her read the text and act perfectly normal. A couple minutes went by and she texted me back, our parents are perverts, I bet they want to watch us again! I sat and thought what to do or say next. My mind wondered back to last week of watching them fuck. I blame the booze I was drinking but I wanted to see it again, I was turned on.
Gen beat me to it. While I was day dreaming she wrote me another text that said, if they want a show, let’s give them one… We both then put our phones away. I noticed that between the four of us we had drank a lot of liquor, which would help lower everyone’s shyness. Gen asked everyone if they wanted to hit the pool or the hot tub. Everyone said hell yeah. We all got up and went to the rooms to change into our suits. Lisa pulled a very tiny bikini set from her backpack. I looked at her with a raised eye and asked, were you looking to show off tonight? She responded, maybe, you know how much that turns me on to show off. We headed to the backyard through the kitchen. I had hoped my parents had moved away from their spot as we were about to walk out next to where they were. As I walked out I looked left and confirmed they were gone.
Lisa and I made our way to a lounge chair to wait for Gen and Tod. While we waited we sat down and started to make out. I ran my hands over Lisa’s bikini top and realized it was so small it just covered her nipples and slightly past. I heard the sliding door open and looked up to see Gen followed by Tod walking out. I couldn’t help but notice that Gen had the exact same suit on but instead of the red one Lisa was wearing, it was white. I told Lisa, I feel like this was as setup! She admitted that her and Gen had been talking and they planned to wear this suit the next time we were hanging out and our parents had left. I told her I completely approve! As Gen walked up I told her I could see her nipples through her white suit which she responded well you’ve seen them before so what does it matter.
The two of them sat down on the lounge chair next to the one we were already on. Tod looked Lisa up and down and said, nice suit Lisa, but yours isn’t see through followed with a frown face. Lisa laughingly apologized to him, pulled her top to the side of each tit and asked, there is that better. Tod perked right up and said absolutely. While Lisa was saying something else I started to scan the parameter trying to find where my spy parents were posted up. It took almost 5 minutes before I finally spotted them. They were on the far side of the yard away from the house behind a large bush in the yard. Great hiding spot, I almost didn’t see them. If we moved to the hot tub they would be extremely close to us but still hidden. I said to everyone, hot tub time! We all got up and walked over to the tub and slid in.
I was first in, Tod following behind me and we took our seats. My girlfriend was behind him followed by my sister. Watching my sister enter the tub I couldn’t get over how amazing her hips and abs and ass and everything looked. I was drunk and horny and ready to fuck. As Lisa got into the water Tod reached out and pulled her onto his lap. I said, it’s like that? Tod asked me if I minded. I responded sharing is caring after all. Gen entered the water and went straight for my lap. The girls relaxed on our laps and the conversation from inside continued out here. I acted like I was looking to the side and whispered into Gen’s ear, our parents are just behind that bush. She turned and did the same, I saw them when I was sitting down, it looks like they’re almost naked, and mom was in her bra and panties. She then went on to say, don’t judge me but knowing they’re watching is turning me on. She felt around and brushed my hard cock and asked, is this because of me, our parents, or your girlfriend sitting on another man? I responded, all of the above, I’m drunk and horny and this is all turning me on. She asked, you sure you want to do this? I said yes, what about you? She said, please play with my pussy, I’m so turned on.
I slid my hand up her leg to her pussy. As I was doing that I asked Tod and my girlfriend if there was any hanky panky going on that we should know about? Lisa responded nope as she slid her bikini to the side and pulled Tod’s mouth to her nipple. She had amazing tits. Gen and I both laughed. Lisa asked what about us. Gen responded, well Johns actually rubbing my pussy right now through my suit and it’s really turning me on. As she spoke the words I could see a shiver go down Lisa’s back. She just loved the thought of Gen and I messing around. It did something special for her to think about. Lisa then said, well maybe I should be honest and tell you that Tod already has two fingers inside my pussy which again got a laugh. I pushed Gen’s bikini bottoms to the side and started to play with her pussy some more feeling how absolutely smooth she was. She leaned back a little bit and whispered to me, suck on my nipples while you do that. I didn’t even have to move her top out of the way, the fabric was so small that her tit popped out just turning to me. I took her right nipple into my mouth and started to suck on it. I could hear and feel Gen moan. I worked two fingers into her pussy and rubbed her clit with my thumb.
After several minutes I shifted and noticed that Lisa and Tod were just watching us. I said, you two look like a couple of perverts watching us. Lisa responded, can you blame us, it’s so hot watching a brother and sister be so sexual. Gen whispered again to me, let’s give everyone what they want! I smirked as she raised up out of the tub. She told me to lay down on the ground and took her bottoms and top off. I climbed out as well and slid my trunks down then laid on the grass right next to the hot tub. Gen placed a foot on each side of my body facing away from me and then slowly lowered herself down onto my cock in a reverse cowgirl position. I watched as her pussy lips parted as my cock slid in. All I could think about is how amazing this felt, then the reminder, this was my younger sister’s tight pussy. I could see my girlfriend and Tod were at the side of the hot tub looking out and down at us. Tod reached out of the tub and grabbed my sister’s boobs and started to play with them. Gen started to increase her moans, clearly putting on a show for everyone. She gyrated her hips while my cock was inside her making a motion someone would do with a hula-hoop. I could hear her moaning, does everyone like watching me fuck my brother.
Tod climbed out of the tub finally, slid his suit down and stood in front of Gen. She naturally leaned slightly forward and took his cock into her mouth. Lisa stood on the side of the tub and said I feel left out, who’s going to fuck me now while slightly bending over? That’s when my dad broke his silence. Likely they just couldn’t take it anymore. Out from behind the bushee walked my mom and dad, he in his boxers and she in her bra and panties. They were a very sexy sheer see through set even from the ground I could see her nipples through them. God they looked great, with each step I could see them bounce and jiggle slightly. Expecting Lisa to shriek in shock, all I heard was, about time. My dad walked up behind my girlfriend, pushed his boxers down and slid his cock right into her pussy. Lisa bent one knee and put it up on the side of the tub as my dad started to thrust away. Gen and I froze in shock. Up until now we were just putting on a show for our perverted parents and now the line has been crossed. Our dad has his cock deep inside of my girlfriend’s pussy and wow did it look great. We watched him thrust over and over watching as her tits were jiggling.
Even though Gen and I were frozen I could feel her head moving back and forth. Tod was still standing in front of her fucking her mouth. Tod started speaking by saying, surprise!!! Ha ha we were in on it. Lisa and I spoke to your parents after what had happened last week and came up with a plan for them to be able to watch us again. As he was finishing his sentence he turned to Lisa and continued, now we didn’t say anything about joining though. Lisa, still getting fucked looked at me and finally asked, is it ok John or should we stop? Before I could respond Gen pulled Tod’s dick out of her mouth with her right hand and said, let them fuck, this is so hot. She stroked his cock several times and put it right back into her mouth. I responded, sure dad, enjoy my girlfriends tight pussy. I could see Lisa’s eyes rolling back in her head. Todd pulled out of Gen’s mouth and walked over to Lisa’s head. Lisa bent over further and took his cock into her mouth. My dad grabbed her hair and started to pull and push her head onto his cock. Watching my girlfriend getting spit roasted by my dad and my sister’s boyfriend was a sight to see. We could hear her gagging and slurping and moaning.
Gen pulled up off my cock and still naked walked over to our mom. Gen said something to our mom which mom looked very hesitant to whatever Gen said eventually nodding yes in agreement. She then slid her panties down showing a perfectly trimmed bush followed by her taking her bra off exposing the most beautiful pair of DD boobs. They dropped slightly as you’d expect from her age but not too much. She then sat down on the ground and laid on her back. Gen looked over her shoulder back at me and said come help me. I stood up and started to walk over just in time to see Gen go to her knees in front of mom, lean over and run her tongue up mom’s clit. After several licks she told me to start sucking her tits. I took a knee next to moms left side and looked down at her. She had her eyes closed, I couldn’t believe I was looking at my naked mom while my sister was going down on her and I was about to suck on her tits. I leaned forward and with slight hesitation took her tit into my mouth. Mom arched her back with pleasure she was get from both of her kids. Gen was really doing a number on her and she was moaning so loudly. Several minutes had passed when Gen screams out of nowhere, oh fuck yes dad. I looked down my mom’s body and I see Gen, still on her knees with her face up to mom’s pussy but now behind her our dad has slid his cock into his daughter’s pussy bottoming out to his balls. He didn’t move just stayed inside her enjoying the moment. I heard our mom say to him, I thought we agreed we weren’t going to fuck them honey. You promised. Dad responded, I know dear but her pussy just looked perfect. I had to put my cock inside her. Gen pleaded with her mom, please mom it feels so good, just this one time. Our mom replied, no that’s going too far, this is wrong.
I laid down next to my mom and as I did I pulled her on top of me. She was now straddling me, her pussy just an inch above my cock which was pointing up to my face. She said, no, we agreed. I replied to her saying humping isn’t fucking, then I pulled her down so that her pussy was resting on my cock shaft. I could feel how wet and warm her pussy was. I then slowly moved her back and forth so that she was sliding along my shaft. As I was sliding her along the shaft of my cock she kept repeating, we can’t, this is too much. It only took several seconds before I could feel that she had taken over. She matched the speed that I had pushed her but then slowly increased speed, still repeating no. Her words then changed from no to this feels so good, I can’t believe I’m doing this. I reached up at her swaying boobs and took them both into my hands. They felt great. My mom was now uncontrollably humping and grinding against my cock. As she was humping me I looked over where Lisa had been previously. She was now sitting on the ground and rubbing her pussy while watching. Tod was next to her doing basically the same, slowly stroking his cock. Their eyes went back and forth between Gen on all fours with her dads cock deep inside her and over at me with my mom humping my cock.
I looked up at my mom’s face and told her I was getting close to cumming and I couldn’t last much longer. She didn’t even open her eyes, she just yelled, not yet, she reached down and pushed my cock up, slid farther forward and impaled her pussy on my cock. She started fucking me with such speed. She looked over her shoulder at her daughter and husband and said, yes, yes you can fuck her, fuck her and cum in her pussy, I can’t believe we’re doing this! My dad was fucking Gen so hard making her tits sway hard back and forth with every thrust. My dad was the first to go. He reached around, grabbed both of Gens melons hard thrusting deep and grunting as he filled her pussy with his hot cum. I was right after him having seen this, I yelled that I was cumming and my mom’s pussy milked every last drop of cum out of my cock. While my orgasm was ending I could feel my mom’s body shaking from an orgasm of her own. She slowly pulled up off of my cock and I could see my cum starting to drip out of her pussy. As everyone started to catch their breath I started to wonder if my parents were going to be ashamed of what they did again just like last time.
