In her pussy

"FUCK....gonna cum Stacy..." you warn her just before you feel your cum start to erupt inside of her, her eyes rolling back into her head again as you thrust away inside of her and pump her full of your seed.

"UH...OHGOD..." she moans as she feels the last of your cum shoot into her, her legs still hooking into your back as you start thrusting into her again.

"OHGOD...John...stop...don't cum in me again..." she cries out as you start bottoming out inside of her again, her cunt walls grabbing and pulling on your dick as she cums all over it for a second time.

"If you want me to pull out this time, I'll pull out," you tell her, blatantly lying to her since you had no intention of doing so.

"OHGOD...pull out...I'm not on the pill right now..." she hisses as you start to hammer into her tight cunt, her walls clamping down on your dick as you speed up your thrusts into her.

"NO...GOD NO...pull out John...don't get me pregnant..." she moans as she starts to push her hips frantically back into yours, losing the battle with her own desires.
