My Freaky Sisters Use My Cock

You won't believe what happened to me today. My sisters Tana & Taurus went out to a rave & they came home pretty late. I was bored & in Taurus' room masturbating with her panties. I didn't hear them come home & Taurus walked in on me. She started teasing me then called in Tana to show her what a pervert their little brother is. I was embarrassed but it was kinda hot so I just kept masturbating. Tarus started giving me a handjob. I couldn't believe it, but I just stayed cool & went with it. Then she convinced my sister Tana to give me a blowjob! Insane. They both must've been pretty "out of it" from their night of partying. Tana wanted to get laid & didn't, so Taurus convinced her that my dick would do just fine. Tana was reluctant at first, but eventually her libido won over & she rode my cock. Unfortunately I couldn't contain myself & came inside her while Taurus laughed. Oops! Oh well. They're my sisters; I'm sure they'll forgive me.
