Picked out the Female and Human vials and turned towards Jonathan.
Mary hit Jonathan with the back of her arm sending Jonathan down onto the bed.
Mary landed on top of him and shoved both the Female and Human vials down his throat before replacing them.
Mary then got off to watch the changes happen to Jonathan.
Jonathan then felt that something's not right... no, he feels his stomach start to ache.
He watched as his scales became finer and finer before finally disappearing to be replaced by smooth light skin.
He felt the base of his back as his tail disappeared into his spine.
He watched as his feet and arms finally became human before feeling himself.
Jonathan then felt a strange, alternating feeling where his penis should be, so he checked and was shocked to find a functional vagina.
But that was before he felt a inflating feeling as he watched a pair of C cup breasts grow out of his chest.
"O-Oh my god I'm a female human!" Jonathan exclaimed getting used to her new voice.
"Yesss that'ss right Jonathan" Mary said looking at Jonathan lustfully.
"and you're my slave".
<Joanna's POV>
Mary maneuvered to behind you and started ramming her shaft into you.
The two of you continued in this manner for nearly five minutes when, all of a sudden, your body tensed as you cried out. Your womb was then filled with warm cum that began pumping in waves, filling you with warmth. You continued to take blast after blast of Mary’s cum until you couldn’t take it any longer and tried pulled his penis out of your vagina but couldn't in time. Mary continued to orgasm and blasted you with her seed over and over again. Finally, after an eternity, the source of the flow seemed to dry up and Mary's penis lay, still slightly twitching, against her legs.
