22and he was 24. One day i accidently stepped into the bathroom and he was in the shower. I saw his body for a second. Pale skin, slim waist and good shaped not skinny butt. After a few months later we are in our house. My parents went somewhere for something i dont remember it but we knew they’re gonna come 4-5 hours later. We were 3 kids and i send her sister to play in backyard so we were alone. I mentioned the time i saw him on the bathroom and tried to laugh him. Then i googled naked games and there was truth or dare. We started and get naked eventually. I dared him to bend over and while i am grinding i came on his cheeks. Later i kissed and licked all over his ass. Fyi i didnt know all of this i just wanted to eat that butt. The second time while grinding i got in and started to fuck. And the first time in my life i felt living. It was only for a 1-2 minutes but it was not the only time. I still remember how i hit and vibration in the cheeks.
