"Ladies, ladies," Jon interrupted loudly. "There's plenty of me to go around..." He concentrated. "...especially when I have one dick for each of you."
A second penis sprouted underneath Jon's original. It was just as large, and just as ready for action.
The two girls squealed in delight, and Jackie lay face down on top of Robyn, who was face up. both of them presenting their wet, awaiting pussies, one right on top of the other, their legs intertwined and their breath heavy.
It took some maneuvering, but Jon managed to push both his cocks into both women. The pleasure was immense, and from the groans and moans below him, he could tell the girls were having just as good a time. They began making out with each other while I fucked them both to my heart's content.
We all came simultaneously, and collapsed into a huge pile, breathing heavily and smelling of sex. But then the bell went off for class, so they had to get up and clean themselves off. There was no awkward silence, and they each kissed Jon passionately before they sauntered off to their classes.
