He decides that you may let him go to the next level.

You are overcome by your orgasim and you look down at him, he looks back at you and stands up unbuckling his pants. You start to shake your head and mumble no but as soon as you do you feel his cock, small as it is, open your pussy. You look at him in shock and say "No, please I am not on the pill" and he smiles and lowers his weight onto you to give you a kiss. You taste his musk and your own juices as he plunges over and over into you, despite his small size years of masterbation has made his cock numb and he pounds hard and fast bringing you to a second orgasim.

You beg and beg for him to put a condom on and he either doesn't hear or just doesn't listen as he hammers into you, your pussy clamping and sucking on his little prick as he rides roughly into your supple body. Finally he tenses up and you scream "oh god, no pull out" and you slam on his chest hard enough to leave bruises in his doughy skin as he pushes in as deep as he can and pours what feels like a months worth of built up cum into your fertile pussy.
