Sis-in-Law Vampire Rides Me!

My bro-in-law is tied to the bed, already hard, and completely at my mercy. Dressed in a tight, shiny black vampire catsuit, I’ve decided to complete the ritual that will finish my transformation. I don’t feed like a normal vampire — I feed on sexual energy and cum. And tonight, my sis’s husband is going to give me every drop. I’ve always known that you've wanted me. I've seen the way you stare, the way you get hard when I'm around. Now I'm going to use that lust. I straddle you in the catsuit, sink down onto your cock, and ride you while I talk about how wrong this is. How I'm your wife’s sis. How you're about to cum inside me and feed me so I can fully become the vampire I've been turning into. Heavy taboo dirty talk, possessive riding, and a creampie finish as the ritual completes, and I claim you as my personal cum source. You're not going anywhere — I might need another round now that the change has settled.
