Jealous sister gets wild on Snapchat [MF]

A couple months back I went out with some mates to some dingy tropical themed club in the city when I bumped into an old friend. Steph was a pretty girl, long blonde hair, thin body but her ass is kinda cute. That night however my attention was fixated on someone else, her sister. Not as pretty as Steph but her curvy body and perky tits looked great in her dress. She introduced me and we hit it off. I don’t remember everything from that night but I do remember getting a solid hard on when her sister was grinding her juicy ass on me. I tried to take it further but she insisted that she was dating someone and that it was getting a bit serious. Whatever.
