I was top of a guy a few weeks ago, bouncing up and down on him, his cock was about 9inc.. He climaxed hard in me and I felt his cock pulsating and I blow my load at the same time, it was a vary intense felling and satisfying..
That'll do it! When you feel the cock head start to buck and twitch, banging against your prostate, your own cock will involuntarily release its load due to sheer ecstasy
