Jeff and Steve both went to town with the sex, but since Regina was an insatiable nymphomaniac, you pretty much just had to fondle a breast to bring her to orgasm. Jessica eventually had to tell Steve to stop, since short of the Chronivac, there was no way she'd catch up with Regina.
"Enough," she finally said, pulling a spent and exhausted Jeff away from the still horny Regina. "What's the change you want, for you and for Steve?"
"Twins," Jeff said automatically. "Make us both twins."
"You mean identical to each other or what?"
Jeff grinned. "I mean make two of me and two of Steve."
Well that sounded interesting. Jessica consulted the Chronivac and finally found the twins menu, but under that were all sorts of options, including fraternal twins. She punched a few buttons and watched both guys split.
Jeff split into two Jeffs, both identical, until one began to grow thinner and smoother and the other more muscular and hairy with an enormous cock. Cool! She'd succeeded in splitting Jeff into emo Jeff and macho Jeff.
Steve, meanwhile, was identical for a moment until the Steve on the left sprouted perky tits and the cock shrank down to a sexy clitoris. Steve was now Steve and Stevie.
Nymphomaniac Regina grabbed macho Jeff and immediately began to suck on his mammoth member, but both Jeff's began to stiffen with ecstasy, their minds psychically linked.
