On her stomach

"Fuck!" you exclaimed, getting closer and closer to your release.

She looked at your face intensely. "Are you gonna cum?"

You closed your eyes, trying to hold back your orgasm.

"Baby, are you gonna cum?" She asked again, more forcefully this time.

"I'm…" was all you could say, as the waves of pleasure washed over you.

"Baby, pull out," she said nervously though her moans.

"I'm… close…" you panted, still fucking her hard.

She pushed at your chest this time, exclaiming "Pull out! You can't cum inside me, stop fucking me!"

Before you could react, you felt the first wave of your orgasm wash over you as you hilted yourself inside of her unprotected pussy. You felt the first pulse release inside of her, coating her cervix and walls with your seed.

"Fuck! Pull out, John! I told you I'm not on the pill!"

You groaned as you pulled back, stroking yourself, shooting the remainder of your load over her toned stomach.

As your orgasm began to subside, you slowly stopped stroking, watching a small bead of your cum drip out of her unprotected pussy..

"Fuck, that was close..." Kirsten said nervously. "Will you help me clean up?"

You simply shrugged your shoulders and left, leaving her to clean up the mess.
