I am thinking how quickly he cums. Is this the end of a wank session or is he a premature ejaculator? I hope he is, because seeing a male cum quickly is one of my fetishes. It is very exciting to get your hand on a cock and start to rub it and before you know where you are your hand is covered in spunk. Quite often such males are quick to recover and be ready for another.
Thick, like yogurt! I could commit to sucking on this penis everyday. As long as I am treated to a mouthful of warm, gooey, sperm! Who doesn't want to eat that???
