[Kali go]

Yeah this was weird lol a scarred my mind for a long time.
I was 21 and my stepsister Ari (Filipina) was 24 when this incident happened.
My stepdad set up a small round pool in the backyard mainly for my younger brother and my step brothers.
Me and ari never really used it at any point so my stepdad told us we should go enjoy it too before the summer ends.
So we agreed to go outside and have a swim with the siblings. It was going to be a bit awkward because me and Ari weren’t that close and our personalities were opposite, I was quiet and to myself and she was outgoing and popular. Anyways we went to our rooms to get changed and I just threw on some trunks then went outside and began to swim with my brothers. A few minutes later Ari comes outside in a 2 piece bikini, the first time I’ve seen that much skin from her, she had a very fit body round cup size breasts and a fit apple bottom. I got very nervous immediately as she came into the pool and began playing. She didn’t really talk to me much or anything she more so played with my brothers. Then I suggested we all play a game similar to tag but where one of us are the “shark” and the others are the “fish” once you capture a fish they become a shark and help you. So we began to play that and I start off as the shark, the game wasn’t that hard because the pool wasn’t that big but I went after my brothers first to get them all on my side and the last person left to tag was Ari. She was on the opposite end of the pool from me and my brothers so as we swam over to her she turned around and attempted to get out the pool. She lifted her leg onto the rim of the pool to escape, which is when we approached her from behind, one of my little brothers grabbed the back of her bikini bottom in an attempt to pull her back into the pool, but as he grabbed and pulled her bottom her bent over bum was exposed, keep in mind with her legs apart because her leg is on the rim of the pool. Not only was her full butt exposed but her small brown butthole was pretty much wide open. My brothers laughed and started spanking her butt with one of them even putting his finger in her butt. She finally fell out the pool and yelled at my brothers for pulling on her bikini, then went inside. I waited in the pool so my boner would go down, I was in shock honestly. I’ve never thought about seeing her ass much less her butthole ever. Every time I saw her after that I’d just remember her small round butthole.
