Missionary.

As much as I wanted to continue fucking Deborah while she was doing a shoulder stand I knew she was tired despite being fit from her yoga classes and needed to lie down. However, I wasn't going to let her rest, at least not until after I emptied my balls into her fertile womb!

Deborah squealed when she flopped on the bed after I pulled her legs down. She knew what I had in mind when I slid between her thighs -- pulling me down on top of her, she embraced me tightly with her arms and legs as my cock slip past her wet folds and into her hot depths.

"Make love to me, Michael," she whispered, looking deeply into my eyes. "This is our last night to make me baby..."

"Make us a baby," I corrected with smile.

She kissed me passionately as I started to slowly began thrusting in and out of her.

Normally it would be unconventional to make love to your wife's married lesbian friend but considering that I trying to impregnate all of my wife's friends nothing was unconventional about the fortunate situation I was in. I didn't love Deborah in the same way I did with Sam but she was a very close friend and I was trying to help her out the best way I could -- and that was to make her reach as many orgasms before I came myself.

I stifled her cries of ecstasy when she eventually came, her nails raking my back. When her orgasm subsided I pushed myself upright so I could watch her beautiful face twist in erotic pain and her large tits jiggle while I continued to pump her to her next orgasm.

"God, you're gorgeous," I sighed as I watched Deborah arch her back as another orgasm washed over her body.

"OOOooooooh yes," she purred with a big grin.

I grabbed her ankles and hooked them over my shoulders before I leaned forward, resting my hands at either side of her so my face hovered over hers.

"Cum in me, Michael," she begged. "I want your baby!"

I nearly came there and then with those words. Invigorated by her plea I churned my cock in and out of her hapless cunt -- I could hear and feel her juices frothing.

"Oh God!" she repeated as she started to climax again.

Feeling my balls tighten, I collapsed on top of her, squishing her large tits with my chest, and muffled my groans against her slender neck while I pistoned my cock furiously.

Then I came.

Holy shit did I ever came. I was still thrusting away even as my cock was spewing thick gob after thick gob of semen into Deborah's womb.

When I finally stopped thrusting I kept my deflating cock in her. I unhooked her legs so we could cuddle and kiss in the afterglow of one of the best fucks either of us ever had.

"Thank you, Michael," she whispered, giving me a deep kiss.

"You're welcome, Deb," I grinned, kissing her back.
