"I think it's only fair..." Jenny says with a shrug.
"I don't know. I'm not exactly sure what will happen to me..." Jeff says with fear in his voice.
"C'mon you know what they say about black guys, and besides look at how I turned out." Jenny grabs her much larger breasts squeezes them with a wink.
"Fine." Jeff reluctantly agrees.
After they boot up the chronivac Jeff starts to feel the changes take place. His straight hair begins to curl his formerly grey eyes turn darker brown. Jeff grimaced as his muscles tensed. His skin tone slowly began to darken from a pale to mocha tone. Jeff began to rise going from 5'11 to a nice 6'2. His slim frame filled in with rather athletic muscle. Jeff went from the body of a trackstar to basketball star within moments. Jenny's attention turned to Jeff's now strained underwear. Jeff's already gifted package gained a slight increase.
As the changes subsided Jeff began assessing the differences starting with staring at his now dark arms.
"wow, I feel so..." Jeff flexed "much more athletic!"
"You look like it" Jen said with her eyes affixed on his new ab muscles. The sight of which was starting to turn her on.
Jeff pulls off his I'll fitting boxers revealing his throbbing member.
"I guess some rumors are true." Jeff said admiring his new package.
"why don't you come over here and show me if you can use that thing." Jen said already rubbing herself in anticipation.
