My uncle puts me on all fours on his knees to rub my ass.

Weekend at my uncle's house. i stay alone in his house and when i go into his room i find that he has a huge rubber cock stuck to the glass of the dressing room. although at my twenty-eight years nothing shocks me anymore if it surprises me a little and even more so when my uncle shows up by surprise and puts me on his knees to rub my ass. what a pleasure when he sticks his stiff cock deep inside me.
