My step-dad's friend Mark came over again (he really likes to fuck my little step-sister) and as always ended up fucking Brianna. The three of us were in the kitchen when I told him I wanted to watch him fuck her in the ass!!! Brianna was already dripping wet so we didn't even have to use lube!!!! I had her get on her hands and knees and watched as Mark shoved his huge rock hard cock in her ass!!! He pounded her tight little ass hole until he blew his load!!! He pulled out and we both watched his warm cum roll out of my step-sister's ass hole!! I decided to help her out so I came up behind her... Show more
