Sharing a Hotel With BBC Step-Bro

Me and My step bro are stuck sharing a hotel room together and a single bed. I tell him that he better keep his "big black cock off of me" as joke as I crawl into bed. Later on, I feel something poking me and I realize it .. it's my step-brothers rock hard dick .. . and IT FEELS ABSOLUTELY MASSIVE! I turn around and look at him and tell him how impressed I am by how big it really is and that I definitely didn't think it was that big!! but now!? Now I've seen it. I tell him that I'll let him jerk off to my ass, pussy , and feet as long as I get to just watch him jerk off! He aggress and I start to encourage him to jerk off as he admires my body! Speaking my ass and showing him my toes and feet! Once I can tell he's about to cum, I grab his giant black dick and start biting, slapping, and sucking it! My big dick step-bro likes it so much that he cums all in my mouth !!
