Megan and Jen had died. Fueled by testosterone-induced lust, the men wanted to fuck more sexy men, but they also wanted women to experience the turn for themselves. To not long to put a fat cock in their pussies, but to get their own dick sucked by a hot stud. Mark and John knew just the girls to help out, Sue and Beth, the school's known cheerleading sluts. The pair were no strangers to being filled, so having Mark and John ask them to hook up on the football field after hours, was taken with a yes.
The two girls made their way to their cocks for the evening. Sue, a blonde girl with DD's and a tight ass decided she wanted a piece of Mark, leaving Beth, a black girl with a more fleshy derière to John.
Sue got to work first, stripping the new male Mark of his pants. Sue wrapped her mouth around Mark's shaft and bobbed up and down, making sure to add a little tongue to the suck. Mark couldn't help but moan, finally feeling what a wet mouth could do to a cock.
Beth, stripped down first, exposing a juicy ass and two melons of titties. John was ecstatic to put wis mouth on them, remembering when he had his own. He much preffered sucking on them, them having them be his, however.
Almost simultaneously the two girls hopped on top of the boys, and began riding cowgirl style. Holding their titties in their hands, and watching the bounce of their bodies lead Mark and John to bust.
Immediately the cum began having effects on the young women. Their limbs changed first. Legs and arms were fueled with new muscle, and became encoated by a new layer of body hair. The hands and feet went next, having similar effects.
Sue felt her face changing. Her jaw seemed to be expanding out, with little bits of hair sprouting on her chin and upper lip. Beth looked down at her changing body to see a hairy trail on her stomach.
The girls were too pleasured to scream as their Adam's Apples dropped, and the facial hair began spreading to their necks, leaving full beards on the women.
The titties went next. Sue's DDs slowly shrunk to an A and then to a flat, albeit muscled chest. Beth's perky breasts became no more than some nipples on flat flesh.
The most extreme change went last as the girls, if you could call them that, felt their vagina close, dropping a pair of large and saggy testicles, and a 5 inch rod for Sue, and a 6 inch cock for Beth.
The new men, known as Sam and Ben touched their new equipment and stroked until they became erect. Ben looked at John and knew that his big black cock was going to see its first of many uses
