We start in the pool

A night of very hot weather, after having spent a couple of hours with my current ex-wife, I told her I was going to the pool for a bit to cool off, she said she was resting a little and would join me later. When I arrived, I saw that my brother was also there and we started chatting, some time passed and I see my girlfriend appearing at the door covering her body with a towel and approaching us saying you two and taking off the towel to get in as well. She only had the bottom part of her bikini on, leaving her tits bare, which caused me to have an instant erection and so did my brother, she looked at us and with a mischievous smile got under the water when she came out it was right in front of me rubbing her tits against my cock as I lifted them up, then she stopped in front of me and kissed me leaving her beautiful ass exposed which my brother couldn't stop looking at. When she stopped kissing me, she got under the water again but when she came out repeated the action but with my brother this time, I approached him and started touching his ass while he was touching her tits. We were both kissing each other while we were touching her whole body and she was grabbing our cocks with her hands and rubbing them against her crotch, I wanted to take off her thong but she said no let's keep going like this and enjoy it so we did, sometimes I would lean my ass on the cock and ask her to touch her tits while making my brother masturbate and then I would switch and make her masturbate me while adjusting my brother's cock in her ass and I would start touching her pussy with my fingers, it was at that moment that she said yes put your fingers in the bum and the pussy so we did for a long time making her moan with pleasure until we noticed our cocks were about to explode and she let us go and left us feeling hot. If you liked it, I'll tell you how the night ended later.
