She gave Mike a blowjob.

Oddly enough I rarely got a blowjob from Emma during the five days of our tryst. It wasn't like she didn't like giving them -- she loved giving them when we were swinging -- but rather she didn't want to risk me cumming in her mouth and wasting precious sperm that could possibly impregnate her. But now with five days of my semen stored in her womb she was willing to suck me hard again.

I propped my myself up on one elbow so I could watch Emma stroke semi-flaccid cock before engulfing it whole like hungry snake. With my free hand I reached under her and grabbed a big handful of tit, kneading it. She moaned while she bobbed her head up and down my hardening shaft. When I was finally erect again, she wrapped her lips around the tip of my cock and twirled her tongue around it as she stroke my meaty shaft.

She stopped and grinned at me. "You're not going to cum in my mouth, are you?"

"No, unless you want me to," I chuckled.

Emma paused for a moment and giggled, "We'll see." She licked down the length of my shaft before sucking on my balls.

"Jesus!" I groaned.
