The doctors give shots to the two individuals, first in their most private areas. The shot bears no
pain as the fluid is injected into the boy's penis and the girl's clit. The changes take effect almost
as soon as the needle leaves their sexes. The girl first moans as her vagina begins to push
outward, creating an instant hard-on. The boy looks on in shock as his manhood shrinks down
into his new pussy, already soaked in juices. The girl then develops testicles from her eggs giving
her the ability to impregnate her lovers. She begins to jerk herself off, while her counterpart is left
to finger his new crevice, both now moaning in pleasure. "Time for you to "experiment" with your
other," the doctors say as they finish observing the first stages of the serum. The two are then
taken to a single room with a queen-size bed. They both stare at each other, their naked new
genitals showing. The new "cuntboy" walks over to the "dickgirl" and asks in a shaky voice, "M-
may I... lick it?". To which the she nods, blushing as the boy begins to lap at her cock. She starts
to moan blissfully until the boy stops, putting his cunt right above her penis.
