A few month ago I was on a boys trip in Cancun with my homies, one night we met that UK couple and drank some tequila with them. The dude felt sick and went to sleep so we stayed with his girl and continue drinking all night. She started to be horny af.
By 2am we went to my room and I fucked her in the ass. Once finished she went back to her sleeping bf.
The day after we saw her and her bf again, who clearly had no clue. She smiled at me, she felt absolutely no shame.
