Ugh, but where was my friend hiding that hard and upturned ass?

I have to share a room with one of my friends in a hostel where we go for the weekend. and how was i going to know that my friend was going to sleep naked and that i was going to end up with a hard cock when i saw him like a log on the bed with that hard and upturned little ass all to myself. with how horny i am, i start to jerk off while i can't stop looking at my friend's ass. i'm looking forward to waking him up to fuck him bareback and see him jump with my tail pounding on that ass nonstop.
