Rimmed My Roommate's GF While They Were Fucking

This happened in college. Me, my roommate and his girlfriend were sitting around one Sunday doing bong rips. We were all absolutely lifted and they started making out. I was sitting on my desk chair and the two of them were on his bed and she starts rubbing his bulge over his pants. I started laughing and I'm like, "hey guys, I'm right here." She looked right at me and while making direct eye contact pulled his dick out of his pants and started stroking him. Now I'm getting obviously hard and she's like, "jerk off, I wanna see it." I'm like, "what the fuck?" I looked at my roommate and he just shrugs, so I said, "I dont wanna do it to his dick, let me see your tits." So she looked at my roommate and he just shrugs again, so she takes her shirt and bra off.

Now she's rubbing him and her tits are bouncing and I'm rubbing myself and they're both looking at me. Its weird, but hot. This goes on for like 3 minutes, at which point I just straight up ask, "can I watch you guys fuck?" They looked at eachother and my roommate just shrugs again (he is ridiculously high at this point) so she says, "ok, but this isn't a threesome, you're only watching." So I shrug, and say ok.

So she stood up and took her pants off, then straddled him and started riding. Its honestly incredibly hot, I'd never seen anyone else fucking before. So I'm getting really close and I say "I'm gonna cum, can I cum on you?" She says, "absolutely not." So I say, for some reason, "what if I eat your ass first?" I have no idea why I said this, I had never eaten ass before and really had no interest in doing it. They both about die laughing. My roommate is like, "what the fuck bro?" but he's cracking up. She looks at me, then at him, then back at me, says, "fine, come get it," and leans down and starts kissing him, but now her butthole is on full display.

So I go over to the bed, prop myself on my elbows, and start going to town with my tongue on her button. She starts making happy noises but she's moving around too much, so i put my hand on the small of her back and press down as hard as i can. So now she's staying reasonably still, and he's humping up into her and I'm still tounging her balloon knot like my life depends on it. This was pretty weird for me because I had never eaten ass and I had never had a dick that close to my face either. He starts going "of fuck oh fuck" and she looks back at me and says "cup his balls, he loves it."

My roommate and I both start laughing and hes like, "don't you dare." I reapond, "sorry bro, she's in charge" and grab his sack. I even gave his taint a little tickle with my middle finger. He does the hnnng hnnng hnnnng and finishes, and I am doing my best to keep licking this girl's little butthole while laughing hysterically while my buddy's balls are contracting in my hand as he unloads inside her. So he stops and she stops and I say "are you done too?" to which she responds, "I'm not gonna cum, go ahead and finish yourself."

So I straddle the two of them, rest my balls right on her tailbone and stroke an absolutely massive load out on the small of her back while the two of them make out. Thankfully he had his eyes closed because I do not think I would have been able to handle any eye contact.

I grabbed a shirt from the laundry hamper and cleaned my cum off her back and then the three of us went out for pizza.
