I was at a barbecue with my cousins for one of their birthdays (for this story his name his Aidan). Aidan enjoys playing video games and he just got Roblox on his iPad. I am fifteen and he turned 11. His sister(Maya) and my brother(Ben) were there as well. We go upstairs to play while I scroll through Insta. After a while maya is bored as she didn’t have an iPad to play with. She grabs my foot and tried to yank me off the bed. We get into a sort of tug of war and then my foot accidentally slips up her dress. She gave a small smile as if she felt something nice. She then grabbed my foot and made it go up there again. She kept going and going. I feel myself getting a bit hard and she sees a bulge form. She ignores it and keeps going. I eventually get my foot back and sit on the bean bag on Instagram again. After a while Aidan gets me to play Roblox with him and Maya wants to see me play. She sits on my knee and watches. I wiggled my knee to get her off and start going like a mechanical bull. She gets off balance and touches my d***. It felt amazing. I have ignore the little in my head and keep playing. She grabs my d*** for dear life and kind of gives me a h*******. I stop as I realise we were making a lot of noise. I give her a turn at Roblox and she plays and sits very tightly against me. I decide to play the bull game again. I keep going and going but this time she’s facing away from me and her v***** and b*** are bouncing on my d***. It feels incredible. I bounce and I erupt in pleasure, c** goes straight through my pants then sit there a little. After I realise what happened I stand up as quickly as I can and head to the bathroom to try and clean it off. I use a wet hand towel and wash the stickiness of then a dry one and dry my pants. Eventually it looks ok and I head back. It’s dinner time. I grab food and go sit down. My aunt brings me a cup of sprite when she comes down. We all sit and have dinner ( me my dad, brother, 2 cousins, aunt and uncle). When the little kids finish their dinner they head to watch a movie. I glance over at my aunt and realise how m sitting at the perfect angle to see some of her t*** hanging out. It is milky white at the bottom. My d*** goes hard again.
