In her pussy

Ripping Amy's mouth off your cock, you flipped yourselves over, positioning your cock head at the entrance to her pussy. She grabbed your cock, stroking your lubed prick.

"I'm not on birth control," Amy didn't look scared or nervous, more like she just stated a fact.

"I don't care." You shoved yourself into your roommate's girlfriend, going balls deep on the first stroke. Amy's legs shot out, squirming about the bed as she was filled like she had never been before.

You steadied her legs and moved her knees towards her chest. Your strokes were long, slow, and sensual. Amy's eyes looked up at you with something that resembled love. She cupped your cheek in one of her hands as you continued to fuck her.

"I came when you entered me," She brought your face down and kissed you hard, maneuvering her tongue into your mouth, "No one's ever done that before."

You were lasting much longer than you expected, especially after her masterful blowjob. It was at this moment of gazing into each others eyes that you realized you not only lusted after Amy, you loved her. And you wanted to fill her with your sperm.

"I don't want Hal anymore," She smiled, grasping onto your buttocks with her fingernails, "Put a baby in me, John."

"Are you sure?" Amy shivered, cumming again on your cock.

"Please. Put it in me. I want our children to be like you -- so dominant. Steal your roommate's girlfriend away. Take the pussy that should be his for your own. Take his womb."

Amy sure knew how to dirty talk. You doubled your efforts, fucking her rough now. You wiggled your fingers down in between your crotches, massaging her pussy as you could feel your thick cock work it's way in and out of her, stretching her further.

Amy wiggled a finger around near your ass crack, "I want every drop of your huge cock seed," She shoved her finger into your asshole just as your balls tightened up into your shaft. You lurched, your cock spitting rope after rope of semen in her. "Yes! I can feel it!" She moaned as she gyrated her hips against you, "I can feel it shooting out!" You could feel every bit of you leaking into her. There was so much cum, that you could feel it shooting out of her, covering your shaft in your own seed.

Spent, you fell on top of her, your heaving chest smushing her breasts. Amy was most certainly pregnant with your child. You both caught your breath, covered in each other's sweat. She stroked your hair lovingly.

"What are we going to do about Hal?"
