As long as you pull out

"OK, but promise me you will pull out before you cum. I'm not sure if i'm safe." you say. "Don't worry, i'll take care of it. You just enjoy yourself."
He grabs you by the hips and lifts you up onto the sink and starts rubbing his cock head up and down your folds driving crazy with lust. "just shove it in." you gasp as you kick of your panties from around your ankles and wrap your legs around him.
John has an evil glint in his eye "Your going to have to ask nicely." he smiles.

"Please!" you beg "Just stick it in me. I need it." With a grunt John impales you, bottoming out just short of your cervix. If you hadn't been so wet it probably would have hurt. Instead you just felt like you had just been made whole.
John started slowly pumping in an out slowly at first, then faster and faster. As he fucked you John sucked on your breasts, giving the nipples little bits every few pumps. You can feel his balls slapping against your ass and his pelvic bone pressed against your clit every time he slammed into you driving you closer and closer to cumming.

"I'm gunna cum" John announces as he starts to pull out. You groan in frustration, you are so close to cumming. "Just a little more." You beg as you pull him back in with your legs.
"I don't know how much longer I can hold out." he warns. "Just a few wore seconds." you beg as you inch closer and closer to orgasm.
