"Hm... I have an idea." She said before walking up to the Chronovac and typing stuff in.
"What is it?" Jeff asked, intrigued as Jenny smiled.
"I'm going to merge us, in a very strange way." She said as she clicked enter.
As soon as she did both of them were suddenly nude, blushing as Jeff felt the urge to bend over. Jenny turned around as Jeff walked up to her, on his hands and knees before sticking his head between her legs and grabbing onto her waist with her arms as he looked up at Jenny as best he could.
"We're gonna be a human centaur." She said happily as Jeff nodded, accepting it as he felt the first change.
His arms merged with Jenny's thighs and waist, ballooning them out as her ass merged with his back, vanishing into it as her vagina similarly disappeared. Jeff's hair vanished next as he felt the back of his head merge with Jenny's crotch. His mouth was forced open and became very wet as his tounge turned into a clit. Jenny moaned as she fingered Jeff's mouth turned vagina. His nose shrunk away as his eyes sealed shut, his face gone as his chest barreled out to be larger for their lungs and stomach as his penis shrunk away. His ass inflated to girly proportions as his legs readjusted for quad stance, finishing their change.
