They mistake me for another and rub my ass. wonderful.

I am at the house of a friend who has lent me his room to spend the weekend. i hear some noises that seem to come from a wall. when i'm listening to my back, someone comes and starts playing with my ass. when i go out, the boy is amazed because he thought it was my friend's ass he was playing. i tell him not to worry and to continue with what he was doing. he with a smile begins to eat my ass and the two horny lost ends up fucking. i don't know what my friend thought about this but i'm going to enjoy it a lot.
