Travis made up his mind and as he picked a vial from the box and brought it up to Mary's lips, hiding the label with his fingers of course, he felt an erection begin to stir in his jeans. Mary reluctantly parts her rouged lips, preparing to drink, when Travis stops her. "Mary, wait... First, undress yourself and come stand in front of the tall mirror." Mary makes a sly little smile. "Oh-kaay... Up to something kinky, are we?" Travis shrugged before starting to unbotton his girlfriend's red blouse. "I just want you to get a good view of your transformation, babe..."
Mary discards the blouse and then walkes to the mirror in her bedroom while she continued to strip down the rest of her outfit. Travis followed her smiling, the vial in his hand.
Once totally nude, Mary admired her beautiful, pale and smooth body for a few seconds. Travis snuck up behind her, kissed her on the neck, then brought the vial back up to her lips. "Now, drink..."
She hesitated a bit, then she downed the vial in one gulp, bravely.
Travis stared in anticipation of the changes that were to follow. Both he and Mary herself went wide eyed when the metamorphosis began...
Mary grew taller first, quite a bit taller actually, even surpassing her boyfriend by a bit! Her pale white skin started darkening slowly, until it reached a deep African black and gained a nice sensual sheen. Her blue eyes became dark as well, while her long, straight brown hair became pitch black, curled up tightly into an afro texture and finally shortened back into her scalp, until only coarse stubble remained, her now dark scalp partially visible through it. Mary's slim but soft body firmed up as it gained a lithe, agile looking muscle tone, even a bit of a six pack on her previously smooth belly was now visible. Her round C cup breasts grew bigger as they changed to be more cone shaped, firm and with bigger, almost black nipples standing in attention. Her neck became longer, elegant and swan like, while her shoulders broadened slightly. Her butt also firmed up and became more prominent. Her face changed next, with her traits and bone structure going from caucasian to pure blooded african beauty, with a smooth, flat nose and thick, sensual, meaty lips. As a final touch, ritualistic scar markings formed in some parts on her ebonied skin. Mary has become someone completely different from herself. A proud, beautiful black woman, who looked like she lived within an unspoiled tribal comunity...
She breathed heavily, at a loss for words. Travis hugs her from behind and he kisses her shorn nape, lustfully. He can't help but moan, and Mary could also feel his growing bulge pressed against her firm, naked ass. She stared silently into the mirror. Somehow, the sight of her boyfriend hugging this naked stranger, this strong exotic woman...fondling her breasts, grinding into her behind, kissing and licking her shaved head... Mary felt a bit jealous and betrayed! Travis never exhibited such lust and desire for her as he now did for this other woman... "Sure, she is technically me" Mary tries to reason, "I am her now, I guess...or at least, I control her body. Yes, that sounds better, I think, because I really do not want to think of her and I being the same person... I'm nothing like this nor do I wish to be!" She told herself in her mind, before Travis gently turned her around, looking her into her new face, his hands clasped gently behind her nape. "You are making me so fucking horny..." He tells her in a breathy voice, then squeezes her naked figure in a tight embrace and kisses her soft, plump lips hungrily.
