Sam.

"You should go next, Sam," Deborah suggested.

"Are you sure, Deb?" my wife asked.

"Yeah, I want Mike to cum in me last," Deborah smiled at me.

That was all Sam needed to hear before she straddled me. Her baby bump was noticeable but not big enough yet to give her back problems so she could still ride me like a cowgirl on a bucking bronco.

"I love, honey," I whispered, looking up at her.

"I love you too," Sam replied and lowered herself onto my waiting erection.

I fucked her hundreds of times and I could never get tired of having her hot cunt wrapped around my cock, even with her blessing of allowing me to fuck -- sorry, make love to -- her friends. I just laid back and her do all the work of pleasuring herself. While she gyrated and bounced on my cock I explored her soft body with my hands -- I moved my hands from her thighs to cup her ass then up the small of her back, and finally grab handful of her big tits.

"Oooo..." Sam purred.

"Cum for me, baby," I ordered.

"OOOooooh," she cried as her pussy started to squeeze my shaft.

I pinched her erect nipples and that pushed her over the edge.

"OH GOD!" she screamed, slamming down on my cock one last time to skewer herself.

I wanted to cum in her as she climaxed but I had to remind myself that I still had to cum in Deborah again to try to impregnate her.

When her orgasm finally subsided, my wife collapsed on top of me and we passionately kissed.

"You didn't cum?" she whispered, playfully squeezing my cock with her pussy muscles.

"Saving myself for Deborah," I smiled.

"Oh, sorry!" Sam blushed, remembering her friends were there watching and rolled off of me.

"Ready?" I asked Deborah.

"Yes!" she answered excitedly and hovered her dripping wet pussy over my slick cock.
