Summer Vixen is having her 21st birthday party and she invited her friend's brother, Donny, but none one else is at the party when Donny arrives. You look, Donny had made Summer a slim promise a couple of years back and that promise was that he would capture Summer's anal virginity when she turned 21. Donny had forgotten all about it, but Summer didn't. So she purposely invited Donny a small early to her party to get the deed done.
