If your cock is too small to actually please a woman, or if it doesn't last long enough to get to this point, you'll barely recognise the beauty of a pair of titties bouncing in your face.
This is a familiar sight for my bull.
He loves to suck on my titties as I slide onto his cock. He loves to grab them as he thrusts his cock deep inside me. Most of all, he loves to watch them shake in orgasm as he pumps his seed deep inside me.
