Diamond Foxxxx's niece is getting married soon, but she pleads her aunt to help her with one last item before she ties the knot with her fiancee Peter: she wants to make sure he's loyal. Peter's on his way over, and she asks Auntie Diamond to try to seduce him and see how far he'll let it go. Big tits and all, Diamond's up for the challenge! When Peter arrives, his fiancee leaves to go try on her wedding dress, but leaves him there with her busty, horny, cougar-y aunt. Peter senses something weird's going on when she starts asking him about how much sex he's had in his life, and he definitely knows something weird's going on when she pulls out her big tits and puts his hands on them! Good thing Peter likes older women, because Diamond takes her mission as far as Peter will stick his big dick up inside her wet cougar pussy! And the end of it, after he's fucked her and plastered his cum all over her face, Diamond calls her niece and has such nice things to say about her future nephew-in-law.
