Nope

You continue eating out Kelly until she cums, her fluids covering your face and thighs crushing your head. You're barely aware of that, though, as you cum yourself, moaning into her pussy. In the midst of that, you feel Nick tense and a sudden warmth from your own pussy, and something dripping out as he pulls free of you.

Kelly gets off of you and looks back, sighing. "Fuck, Nick! I said don't cum in her."

"Sorry, but her pussy felt great. What's the problem?" Nick asked.

"Cum makes it permanent!" Kelly hissed.

You lift your head, looking at them. "What?" you ask.

"I'll have to dig through my books and see if there's a way to fix this," Kelly said, shaking her head. "We could have kept having fun, fucking through the night, but no... Now I have to study." She quickly dresses and excuses herself, leaving you and Nick alone.

"Uhh, sorry about that," Nick said. "I didn't know, and..." he takes a few steps toward you, still naked. You watch as his dick bobs up and down with each step. He stops just in front of you, looking uneasy.
