All 'participating characters' are over 18. Another one for my 'extreme' series maybe?
Summer vacations at the lake house were always fun growing up. When we were younger, kids would be dropped off at our cousins and we'd swim and fish at their pond while the adults stayed in the family owned cabin. When I hit 18 though I wasn't really looking forward to that following summer's trip since I wasn't old enough to drink and tool old for the kids stuff but it turned out to be the start of something amazing.
"Why mom, you said I could just go fishing by myself on this trip, I don't want to babysit!" I replied, mom had asked me to look after my younger cousins.
"Your Aunt Carol will be back here tomorrow, her ex is going to take them home, until then just keep them entertained," said Mom.
"Fine."
I stormed off and put my fishing gear away, found the kids to see what they wanted to do. Hide and seek was decided, in the house only so I didn't have to watch for them wandering to the lake. I found one of the always spare bedrooms and hid myself in the closet, I knew they'd never find me but wanted to hide and give myself five minutes of quiet time.
I wasn't in there long when I heard the door open, I looked out ready to burst out and scare the kids but it was my sister Claire, pulling my uncle Rob by the hand into the room. I heard the door click closed then she sat on the bed and pulled his shorts down and immediately started sucking his cock! I was stunned, I'd watched porn and stuff on my phone but I'd never witnessed a sex act in person, let alone saw another man's cock.
Claire got him really hard then she stood up, stripped off what little clothing she had on then got on the bed on all fours, her ass pointing right at me. I couldn't not look, her pussy was already glistening with her juices, not a trace of hair and she looked aroused, her labia swollen and inviting. Uncle Rob got on the bed behind her and pushed his cock into her, Claire moaned in pleasure then rested her head on the bed, changing the angle he had in her.
"I won't last this way hon, why don't you ride me," said Rob, pausing mid thrust.
"Okay but I want you to cum in me from behind when you're ready," she replied.
Rob got on the bed on his back, his cock soaked with her cream, Claire straddled him then fed his cock into herself. I could see how much he was stretching her pussy with each thrust she took into herself, her moans of pleasure told me she was enjoying it and I had never been harder in my life. A few, I'm not sure how many minutes later, the door burst open again and closed just as quickly. I looked and my Mom and cousin Adam stood and froze.
"We still have kids here Rob, lock the door!" she said.
"S... sorry, m... oh fuck yes, my fault, I wanted him bad and didn't give a chance," gasped Claire.
I didn't know what I was going to do, I couldn't sneak out, I was forced to watch everything that was happening.
"Well I'll let you off, this one has been eager to taste his Aunt since we arrived. Mind if we use the other bed?" said Mom.
"Go ahead, do you want me when he's done?" said Claire.
"Do you even need to ask? Just sit right on when he's spent."
I was in some surreal world, I didn't know who to watch, my sister riding my uncle's big cock or my own mom, now naked and laying back on the bed as my cousin ate her pussy. My uncle gasped 'close', Claire got off him and onto all fours then Rob got behind her again, fucked her furiously for a few minutes then groaned, his cock deep inside her as he came. He pulled out slowly, cum still oozing from his softening cock and sat down on the bed. By then Adam was done eating my mom and was between her legs, fucking her slowly as he sucked her nipple. Claire, without skipping a beat, got off her bed, straddled mom's head and lowered her pussy to her mouth.
"Oh fuck that feels good, that's it, drink your brothers cum from my pussy mommy," she said, holding on to mom's hair.
A few minutes later Claire shuddered as she came again then got off mom's face when she got too sensitive.
"You ready for this one, he's not going to last much longer," gasped mom as Adam increased his pace.
"It's been a while cuz, sorry, I missed my favorite aunt and haven't cum in 2 weeks," gasped Adam.
"It won't be the last load I drink today, trust me," replied Claire.
"Cum in me big boy, show me how much you missed auntie Gina's pussy," said mom.
Adam, seeming to do as he was told, groaned then pushed in deep as he exploded. He pulled out, I could see mom's soaked pussy, already leaking Adam's cum but Claire got between her legs and started licking her. I lost it at that point, it'd never happened to me before but I erupted in my shorts, thankfully my mom's moans of pleasure drowning out my hard breathing. When mom had cum again at my sister's tongue, she climbed up and kissed her then they sat up together. Mom draped an arm round Claire as the men got dressed.
"So you think he's ready?" Said Rob.
"Hard to say, I think he's going to freak at first but once he's in her he'll go with it," replied Claire.
"Tell him about his birthday," said Mom.
"Oh, he got home from shopping with Mom, she'd been teasing him all day, low cut top, no bra or anything. I timed it so I was leaving the shower as he got in and gave him a full frontal flash. He looked at my tits and was 'jeez Claire you should cover up' then ran off. I looked through his door and he jerked off right after. He's really self conscious for some reason, pretty shy too."
I remembered that day, I'd stolen so many glimpses of mom's nipples through her shirt and felt guilty. When I saw Claire's naked breasts I almost came right then and had to relieve myself. I didn't touch my cock for a week after that, feelings of guilt stopping me.
"Well if Sarah can't seduce him I say we all just go naturist and put on an orgy in front of him,'' laughed Rob.
"It might come to that, is Sarah with my Dad?" asked Claire.
"No, I think he has Jenny down by the lake, Sarah wants Marcus to have her clean," replied Rob.
"Fair enough."
At that point, someone knocked on the door. It was my cousin Jenny.
"Weren't you with my dad?" asked Claire.
"Yes, I sucked him dry after he fucked me. Where is Marcus, the kids are downstairs crying, they think they lost him," said Jenny.
"What? He was supposed to be looking after them," replied Mom.
"They said hide and seek but think he came upstairs, they know they're not allowed up here so they waited."
"Fuck, lets find him. No more fun until he's been with Sarah."
Everyone left the room, I cautiously let myself out then sneaked over to the corner bathroom and noisily came out, making an act of wondering why they were looking for me. Claire narrowed her eyes at me.
"You were supposed to be keeping the kids entertained, hide and seek is fine but they knew not to come up here bro," she said to me.
"Well I was so pissed off I forgot," I said, I could barely look at her.
I spent the rest of the afternoon playing board games with the kids, everyone I'd watched having sex didn't act differently around each other. Mom and Dad cooked on the grill and my sister played yard games with our cousins. I looked at Aunt Sarah a few times too, she was my Dad's youngest sister, maybe 4 years younger than him but she was hot. She was tall like Dad, short blonde hair and from what I could tell with her always baggy clothes, had a great pair of breasts. I put it out of my mind that their plan was for her to seduce me, my mind was still reeling from what I'd witnessed earlier that day and just focused on keeping the kids distracted.
Next day, Aunt Carol showed up pretty early, her ex was not far behind her, he took the kids then left.
"Hey Marcus, thanks for looking after those two yesterday, it was easier for Sarah to bring them here for me while I finished up at the shop, I'd have had to go meet him halfway otherwise," she said, kissing me on the cheek.
