A week passes, and it's probably the nicest week you've ever had in your life. You have a totally different friend group as a girl, and they make you feel more comfortable than you ever did as a boy. You have way more choice in your wardrobe, and every choice fits you better than what you wore as a boy. You feel less judgemental of yourself in doing stuff that before you quietly told yourself not to do because it was 'too girly'. You just generally feel like this is how you were meant to be!
On the Friday afternoon, before you leave for the weekend, you get a letter from the nurse's office. When you open it you read your old boy's name and it surprises you- it takes you a second to remember it's meant for you. The letter explains you need to go to the nurse's office on Monday morning for a 'check-up'- the inverted commas are in the letter! It reassures you that it'll be fun and is nothing to worry about, and ends with a winky face. You're flustered thinking about it all through the weekend.
When Monday morning comes, you go straight to the nurse's office, and once the door's shut, she asks, "So, liking being a girl?"
"A lot," you smile.
"Great," she grins. "I have a feeling you'll like what we'll be testing for. I always want to make sure the bodies of the people I change are... functioning right." You blush, and she says, "Take off your clothes, please."
Your hands shaking, you do as she asks. You step out of your shoes, pull off your tights and skirt, and unbutton your shirt. She giggles as she sees you hesitate about removing your underwear, and seeing it you undo your bra and drop it to the floor, revealing your breasts, and step out of your panties. "Now, follow me," she instructs.
You walk through a door into a room with a clinical yet comfy-looking bed, and the nurse says, "In a moment, my colleague will bring out a partner for you. Ah, here he comes!"
A handsome young man steps through a door on the opposite side of the room, and you realize he used to be one of the girls in your class. There's nothing womanly about him now- his naked form is handsome and faintly muscular, his muscles large enough to hold you down and pound you if he wanted, his jawline is firm and gives him a self-assured smile. Most intriguing to you of all, naturally, is the large thick penis and heavy-looking testicles that hang under it.
Instincts seem to take hold as you see him, your body reacting eagerly. Your nipples and clitoris grow erect and your vaginal juices have begun to leak. It's hard to place how seeing him makes you feel, but the word soon comes to you- emasculated. Seeing a handsome man reminds you that you're a woman now, and how you're now able to get made pregnant by men. The nurse implied that, at least.
The boy comes up to you, tilts your head up so instead of staring at his bare chest you're looking into his eyes, and says, "Are you OK with us doing this?"
"Y-yeah," you reply, and you whimper as his large hands softly cup your breasts. They're so firm and large against you, and as he carefully pushes you onto the bed your heart is racing.
The nurse finally admits exactly what you two are 'testing'. "Okay, when you're ready, we'll have a scan running to test the fertility of her ovum, and the potency of his sperm."
The last part of her sentence makes a shiver of primal anticipation run through you, and your mind overflow with thoughts about what you two are about to do. A white drop of precum oozes from your lover's cock, and you consider how inside the soft sac pressing at your thigh are literally hundreds of millions of tiny cells all aching to mate you.
He leans in to kiss you and you kiss him back, whimpering into his mouth as his manhood rubs over your clitoral hood and nub and your juices combine around your slit and his head. He thrusts inside and you groan and cling to him to hold him steady, his shaft pushing unabated into you until his balls press at your flat crotch.
Your breathing hitches further still as he kisses breathlessly at your neck, your hands clenching at each other so as much of you bodies can be intertwined as possible. It feels like your two bodies might just meld into one- until his hips pull back and start thrusting firmly in and out of you. Pleasured sounds fall from your mouth in conjunction with desperate gasps for air through the pleasure, the plaps of his sac slapping against your flesh reminding you of the reality of the situation- he is male, you are female, and he is mating you.
The firm touch of his body on yours seems to heighten your pleasure further and further, and you respond by clenching tighter around him and your erect points throbbing with pleasure, until eventually your peak arrives. Your whole body shakes and your muscles tighten up and you moan still more, hastening his own thrusts.
Once the high starts to subside, he's still coming to his climax, and horny thoughts still control your mind. There seems to be one inevitable outcome from all this. A young man pinned you down and fucked you, without any protection and at the peak of both your fertility. Your biological imperatives were about to be satisfied.
You heard him grunt deeply into your ear and felt his cock twitch and pulse inside you as he began to splurt thick cum into your pussy. It went on so long to you it seemed like every single drop of seed in his balls ached to escape his body and impregnate yours.
Once you both came down from the high, he gave you a passionate kiss and pulled out of you, his semen dripping from your hole. "Well done, you two," the nurse said. "Not only have you both done a great job at having sex, our tests show you're both perfectly fertile. Look..."
You both looked up at a video screen that you realized was inside you, and saw an ovum with masses of sperm surrounding it and eating away at its outer walls. One eventually moved inside, and your heart raced.
I'm pregnant, you think to yourself.
