Babymaking marathon.

When I finally got hard again (with help of Catherine's mouth) I had her get on her hands and knees while I knelt behind her. I rested my hands on her ass cheeks and pulled them apart so I could have an unobstructed view and access to her dripping wet and swollen snatch. I lined the tip of my cock to her pussy lips but before I could push my hips forward Catherine pushed her ass back and her pussy swallowed the entire length of my shaft.

"Ooooh, yeah," she cooed as she moved her ass back and forth.

I looked down to stare at my cockhead almost slipping out each time only for her to slam her ass back against my loins. My hands caressed her ass and small of her back, while I let her do all the work of bringing herself to orgasm. When she finally climaxed, she let out a loud moan while her body stiffened and her cunt spasmed around my cock. However, I wasn't going to let her savor her orgasm, so I grabbed hold of her wide hips and pulled her towards me — I pistoned her on my long, thick shaft, with each hard thrust causing a loud slap of flesh against flesh and a satisfied moan from her mouth. It didn't take long for her to cum again but I continued to pound away. By her third orgasm, Catherine had collapsed face down on the mattress with me squatting over her propped up ass, drilling away at her pussy. I made her cum a couple more times later before I had to cum myself.

After a brief break to rehydrate we tried other positions, even googling some I never tried before. We eventually gave up the pretense of making love to try to get Catherine pregnant because her pussy was leaking semen despite how hard she tried to keep it inside her — we fucked for hours into the night because we needed to have sex with each other.

"I'm so glad you'll be the father of my baby, Mike," Catherine whispered, giving me a kiss as she cuddle against me in the afterglow of our last orgasm of the night.

"Our baby," I corrected her and touched her flat belly as we drifted to a much needed sleep.
