Mary got up from her chair and walked to the mirror again looking deeply at her masculinized version while pondering. "Hmm" she thought, "While getting a sex change is already of itself pretty kinky, if you look really closely you can still see some actual resemblance to who I really am... What would be really fun and arousing is if I'd make myself into a completely different person, to be someone else, well for a while at least! There's no danger anyway, since I did see that there's a complete restoration vial in the box. Let's see, who do I wanna become?... Definitely no animal stuff, that's just not for me... Definitely someone male though, on this I have no doubts! Making myself a guy is the thing that makes me horniest, apparently, which is a bit strange since I definitely never had any doubts about my gender and sexual before now... I mean, I am a very attractive young woman that just about every guy swoons over, I have a boyfriend who really loves me and a generally nice life... Why would a beautiful straight woman like me even consider giving herself up and become just some average guy? That's just stupid and wrong, isn't it? Isn't it?... Dammit why am I getting these weird thoughts of wanting to be a man who looks nothing like me? I'm a woman, I should want to be a woman! Shouldn't I?... Oh crap, what the hell am I thinking? What would my boyfriend say? What would my parents say, or my friends and everyone else? Dammit, speaking of my boyfriend, John will be coming over in a few hours... He can't find me transformed into this male version of his lovely Mary!"
Mary rushes to the box with the vials, grabs the reversal one and drinks it whole. In a couple of minutes she painfully changes back into her original form. She goes to check at the mirror and in part she feels relieved to see that she's back to being the drop dead gorgeous young woman that she's always been, with her slim feminine body, her long legs, her silky pale skin and her beautiful face and long black hair. But the strange and kinky desire to be just an average guy, at least for a while, kept nagging at her mind. John, Mary's boyfriend, will be coming over to her place in a short while... What will Mary do?.....
