Your girlfriend convinced you to let her wear a transparent swimming costume to your friend's pool party. You hadn't made her cum in weeks so you knew she was going to fuck the first guy that approached her. What you didn't know was that she was so horny
This is now the third time your girlfriend has "convinced" your bully to leave you alone. But just like the times before, she refuses to thank him for the dick the way he ordered. Looks like you're still fair game.
