Maybe it was because she was a bit drunk from the wine, but somehow Jen didn't feel scared, shocked or repulsed at all by having suddenly grown a huge cock. She felt actually more aroused than she'd ever been in her life. She sucked her own cock for a full minute then she felt like undressing and stepping in front of the tall mirror to admire her naked figure with its new masculine addition. Her body was a near flawless thing of sensual female beauty and the enormous, undeniably male erection stood in stark contrast with the rest of her. Aroused as she was, she thought that maybe it wasn't the cock that was out of place, maybe it was all the rest of her that didn't match... She grabbed the strange bottle of lotion and examined it again... "Salve of transformation, apply for wonderous changes" the label read. She turns the bottle around and she also reads "effects last for a limited duration, minimum one full day, up to a maximum of one week".
Jen felt like knowing this cannot have permanent consequences, she might as well go crazy with it. Without giving herself the chance to change her mind, she sprays herself all over with copious amounts of the transformative salve, noticing the bottle never seemed to get any lighter, like its contents were infinite. Well, it's magical of course, she thought. Jen took care to spray over every inch of her body, face and hair except on her newly formed penis, since she thought that part needed no further changes, it was already perfect the way it was!
Staring into the mirror in anticipation, her arousal grew as she watched her stature grow as well. She gradually but steadily becomes taller as her breasts recede back into a flat, masculine chest, her waistline filling out and her shoulders widening to grant her a much more appropriate, manly frame. Jen reaches underneath her scrotum with a still growing hand and she's happy to confirm she no longer possessed female genitals and she can officially consider herself a man now. Though she did wonder for a moment why she felt so happy at the thought of becoming a man, she decided she didn't care at all, because she WAS truly happy with this change, which in her mind objectively a change for the better!
Jen feels a surge of strength and energy as testosterone pumps through her body, causing her muscles to expand quickly into the physique of a well trained soldier, dark thick body hair soon forming as well all over but especially over her impressive pectoral muscles and around her crotch. A pronounced adam's apple bulges from her strong, thick throat and she smiles with mirth as she watches her face grow and rearrange into that of a handsome young man. She was pleased to notice that apparently she was also changing race, going from white and blonde to very very black! As her skin reaches its final ebony color, Jen also watches her blue eyes turn black and her long shiny blonde hair recede into a pitch black faded buzzcut with a rough afro texture.
As the transformation ends, Jen tests her new voice and she's very pleased with the new deep, warm, rich and vibrating masculine tones she can now call her own. She also notices that not only did she change sex and race, but she also wasn't 35 anymore, she was now a 20 year old man. This fills Jen with newfound confidence and lust for life and she flexes her new muscles in front of the mirror. She easily decides to use the he/him pronouns from now on and renames himself Max.
Max goes digging through the closet searching for some clothes left behind by Jen's many ex-boyfriends and he actually finds a nice suit and tie that should fit nicely. He gets dressed and smiles confidently at his image in the mirror as he straightens his tie. Max feels he's been given a second chance at life and he doesn't intend to waste it by sitting at home alone drinking wine and getting bored. He's turning a new leaf, he's going to go out right now and meet some ladies (yes Max is a straight man now). When the effect of the transformative salve eventually wears off, obviously Jen would apply it all over her body again to turn back into Max, that's a no brainer, he thinks to himself.
