Whenever he calls around to see his aunt I always notice his eyes all over my legs and bottom so today as his uncle is out and we are all alone in the house here I would give him a very special little treat. I take off my tiny little thong panties and bend over for him on the end of the bed and then I push my bottom out hard so that he can see EVERYTHING that he wants to see as he unzips and shoots his hot thick cum all over me! I know that he is DESPERATE to push his big hard throbbing cock into me there (his uncle wouldn't be very pleased I'm sure...) so perhaps next time I will let him? I'm sure that anal sex is something his prim and proper girlfriend would never let him do... So I guess it's up to his aunt?
