Nothing

You slide your fingers in and out, move them inside your tight and slippery hole like a madwoman and you feel how you're on the edge...! And there you stay, not crossing it and remaining just a hair away from feeling the biggest climax you could imagine.

"Fuck fuck fuck! Why can't i fucking CUM!?", and as if to answer your question, the phone you left next to you rings, it was the same number from that woman who truned you into a girl and before you could even pick up, the voice of the woman comes out of it.

"Hey sweetie~! Seems you like your tight cunnie, huh? Love how it clamps down just when you're about to cum~ Hehehe...", the woman says in a clearly smug voice and somehow not only knew how you were masturbating wildly but also unable to cum as she just mocked you for it. Before you can ask her she talks once more, "You really thought just your fingers would work? Of course not girl! I told you, your pussy would crave some attention and it only wants boys~! So you can play all you want but until you have a big fat cock hilting inside you... Enjoy edging!"

With those words she hangs up the phone, a call you didn't even pick up in the first place and while you wanted to dismiss her words so badly you somehow knew they were true, you would only be able to cum having sex. But then you thought a bit about it and smiled smugly, "Bet at least half a day passed while i was busy with this... While i can't cum at least i can keep myself busy and get no chance of getting knocked up and stay a girl forever!", you say confidently and grab the phone to check the time and then you freeze as the time shows only 10 minutes passed, what you thought were at least hours were in fact a mere fraction of that time and it dawned on you that the feeling of being about to cum didn't calm down and instead even grew, you understood that you had to cum or you'd go crazy, but to cum meant to have sex wich also meant just a small mistake doing that and not only would you say bye to being a guy but also saying hello to being a mother.
