My roommate agreed to let me join him and his girlfriend in their exercise routines buuuut... I'm more interested in working up a sweat a different way, smashing down the sexual tension that's existed between a guy with a nice dick and the cute horny tranny living with him! And what better time to make my move when I know his girlfriend won't suddenly show up and ruin our fun? I start by giving him a floor-soaking sloppy blowjob that works him up into fucking my face, which gets him hungry to eat my slutty ass (with the same mouth he uses to kiss his girlfriend). Then we get to what I've been craving: his big cock slamming into my butt, over and over (and even making me cream from my fuckhole a little!) through doggy and missionary and piledriver position, before he gives me a nice creamy load in my mouth. Next time I think we'll risk it while his girlfriend is visiting...
