The Key to Her Heart

Boy meets girl. Girl rejects boy. Boy runs off suspiciously fast. Girl follows boy, finds girl she's never seen before crying in an alley...wearing boy's clothes...with suspiciously similar features...

The Key to Her Heart is a spinoff of Momo Impact (itself a spinoff of Love Is Neon Green), hosted on Slipshine.

It turns out that the boy, Jules, changes sex spontaneously whenever distraught (m>f) or agitated (f>m), and that the girl, Nadia, is a closeted lesbian. Nadia realizes who Jules is fairly quickly, but finds her female form hot enough not to care, especially with his secret being an incentive not to out her. They have sex in the alley, and start a secret relationship, Nadia pretending not to know.

The first chapter can be read for free, but you'll have to pay for the rest.

This series contains examples of:


 * All Just a Dream (A few times, after sequences like Jules being gangraped by Nadia's friends. Unfortunately, this leaves him thinking it's a dream when .)
 * Blackmail (Poor Jules...)
 * Butt Monkey (Jules.)
 * Cannot Spit It Out (If Nadia had admitted to her friends she was gay and to Jules that she knew her secret, a lot of things could have been avoided.)
 * First Law of Gender Bending (Jules sees himself as male, but since the focus is his relationship with Nadia, especially when he thought she didn't know, we pretty much always see him/her as a girl - since moving in with her, he seems to have pretty much gone female full-time, including taking jobs in female form.)
 * Also, a running plot thread of Momo Impact of an alien who turns any man who gets too close permanently female is revisited.
 * Gender Bender (Jules, of course. .)
 * Gender Blender Name (Actually "Julian" and "Juliet," but pretty much everyone calls both "Jules.")
 * Hermaphrodite (Apparently what happens when Jules gets the flu.)
 * Hoist by her own Blackmailing: when accidentally refers to Jules as Julius while he's in his female form, after he and Nadia have come clean to eachother, Nadia starts asking her some questions. It does not end well for the blackmailer.
 * If It's You It's Okay: In the beginning, Jules is rather ashamed of his female self, and only acknowledges it to have a relationship with Nadia. Eventually becomes an aversion, as he apparently becomes far more comfortable as a woman..
 * Involuntary Shapeshifting (Jules, based on emotion; .)
 * Jumping the Gender Barrier (The entire premise, as well as .)
 * Kick the Dog: pretty much everything does to Jules after she finds out about his condition.
 * Love Makes You Crazy / Evil / Psycho Lesbian : again, - she's the reason that Nadia doesn't want anyone to know about her lesbianism, as she started pretending to like boys just so that  would stop being so psychotically possessive of her. when  finds out that Jules is using his girl half to get close to Nadia, she starts blackmailing him into being her sex slave with the threat of telling Nadia about it.
 * Murder the Hypotenuse (Or at least blackmail and sexually torture the hypotenuse.)
 * Peek-a-Bangs: Nadia.
 * Porn with Plot (It's Slipshine, what do you expect?)
 * Lampshaded after a flashback, when Jules asks his mother if she had to go into "so much detail" about his/her conception.
 * Power Perversion Potential (Again, Slipshine.)
 * Really Gets Around: Jules' mom has a very active sex life for a single mother, at one point actually trying to set up Jules with one of her past conquests.
 * Touched by Vorlons
 * Uncanny Family Resemblance: Jules' female form is almost identical in appearance to his mother..
 * Voluntary Shapeshifting (Jules has learned self-control to this point, except, of course, when it's most inconvenient.)
