He joins the girls.

I had already cum twice but I was still hard -- with five beautiful, well-endowed lovers it came to no one's surprise I still had my special youthful vigor and endurance from my senior year of high school. I briefly watched Stephanie and my wife passionately kiss and they reminded me of the times the three of us fooled around in high school. My mind slipped back to the unforgettable memory of Stephanie coaching Elizabeth how to give a blowjob, with me as the guinea pig, and my future wife swallowing my load I had blasted into her mouth (and onto her face, which Stephanie licked off).

"Mind if I join you, girls?" I asked, standing over them with my saluting erection.

"Please do," Stephanie purred. "As much as it was fun being fucked by Elizabeth, I need a real cock in me!"

"And I don't want you to cum on our faces!" my wife giggled. "We're trying to get pregnant, remember?"

The girls rolled off each other and, letting the long, double-ended dildo slip out of their soaking wet pussies, they laid back on the carpet with their legs spread apart for me. I wanted to fuck them both at the same time but unless I suddenly mutated with a second dick I knew that wasn't going to happen -- so I had to make a decision with the dilemma I faced every time we had these orgies.
