Yes and no.

"Honey, I really want to knock you up but..." I started to say but Elizabeth interrupted me.

"This is our last night with our friends and you want to last as long as possible," she finished my sentence with a nod. "I understand."

"I'm still going to make love to you," I assured her.

"I know," she smiled. "But promise me you'll cum in me?"

"Of course!" I pulled her down on top of me and kissed her.

My wife moved her hips until her pussy lips found the tip of my cock and she pushed down. We moaned in each other's mouths as her cunt swallowed my cock whole. She broke our kiss and pushed herself up, resting her hands on my chest for support while she gyrated and ground herself on my loins. I reached up and cupped her large tits and tweaked her erect nipples with my index fingers and thumbs, causing her to gasp.

"OOoooOOoooh!" she moaned while she started bouncing up and down my cock. I cupped her jiggling breasts, kneading them as she brought herself to climax.

"Cum for me, baby," I goaded her, pinching her nipples again.

That pushed her over the edge and my wife let out an orgasmic cry as her pussy clenched around my shaft. She collapsed on top of me and I petted her hair while she came down from her orgasm.

"I love you," I whispered.

"I love you too," she replied softly while teasingly squeezing my cock with her pussy, "but so do our friends."

I looked at the other girls, who were cuddling and kissing while Elizabeth and I were making love, and I didn't want the night to end -- but at least I would make sure we wouldn't forget it.
