私の淫乱な義理の妹が私のお尻から口へのファンタジーを実現させたなんて信じられない

I walked in on my step brother watching porn and who knew he was into such filthy things?! He was jerking off watching some girl suck dick after it’s being in her own ass… obscene! Yet kind of a turn-on… I asked him if he’s ever tried it, he said no… so I asked him, “well, do you want to?” I get why people are into this now! It’s so delightfully nasty sucking dick after it’s been in my ass… especially when that dick belongs to my step brother. He fucks me in the ass and dips it in my mouth and then slides back into my ass and then again in my mouth until he cums on my asshole, shoves his dick back inside me and then gets me to lick him clean. So hot! Let’s hope we have the house to ourselves again sometime soon…
