Mary learns about the dangers of steroids

Mrs. Greenwood was wearing a blue blouse that hugged her bulging chest nicely. Mary had known on a conscious level that the woman was beautiful, but ever since she got her new parts, she was seeing every woman in a new light. Mrs. Greenwood was a mother of three and she looked it in the best way possible. She was pleasantly plump, with a pale round face and a soft, curvy body. Years of breastfeeding and pregnancy weight gain and had given her massive, pillowy tits.

Mary wrote notes with one hand and with the other gently caressed the tip of her cock through her pleated skirt. Because of her size, she had to tie the monster to her thigh. The arrangement wasn’t very comfortable, but it did give her convenient access during class. Meanwhile, her naked balls pillowed against the cool desk chair seat.

“Yesterday we discussed the effects of testosterone produced in the testicles on the male body. Hair growth, muscle growth, deepening of the voice. Today, let’s discuss what happens when an individual uses synthetic testosterone in the form of steroids.”

Mrs. Greenwood started to write “steroids” on the white board, but dropped her marker half way through. She bent over, giving Mary a quick glance at her bulging tits. Then she quickly righted herself, causing her bosom to bounce and jiggle. A jolt of precum erupted from the tip of Mary’s cock and it took all her strength not to moan.

“The effects of steroids are most startling on women. Athletes, female body builders, even amateurs. When women take steroids, they risk undergoing a process called virilization. What do you think this process causes?”

Mary raised her hand. Even if she was the corrupted servant and breeding partner of a sex demon, she was still an excellent student.

“Growth of body hair and facial hair. Deepening of the voice. Increased muscle mass.”

“Good, Mary!”

Mary smiled and accepted her accolade with canned grace.

That morning, Mary had awakened to discover the source of her itchiness from the night before. Over the course of a single night, she had sprouted a dense thicket of pubic hair all across her crotch. Her smooth scrotum was now covered in a fuzz of little black hairs. Her crotch was not the only victim either. Her armpits, which had never been very hairy before, were now two forests of curly brown. Meanwhile, her forearms and legs were sprouting their own light fur.

She initially panicked and ran to the bathroom to shave it all off. Just as she got hold of the razor, the image reflected in the mirror shifted. Suddenly, Mistress Rasha appeared in all her glory. The demon reached through the mirror and grabbed Mary’s razor right out of her hand.

“I gave you this manhood for a reason, my young ward. You can’t fight these changes. It is your destiny to become a beast of pure lust. A synthesis of male and female.”

Mary hung her head. She felt itchy and strange with the new hair, but her mistress’s will trumped everything else.

“Yes, Mistress Rasha.”

“Don’t look so sad, darling. This is a happy time. In time, these changes will feel so good!”

The demon reached forward and grabbed Mary’s cock. Immediately, Mary reached full mass and began to rock her hips back and forth as her mistress jerked her off.

“Wait, mistress…heh…if you…uh huhhh…do that…I’m gonna…gonna…cum!”

Rasha disappeared in a flash, leaving Mary to splatter the mirror with thick ropes of semen.

“Many women who take steroids hope to only experience muscle growth, but are often left with permanent unwanted changes to their bodies. They voices become masculine, their bodies get bulky and hairy, their breasts shrink, their clitorises grow. Some even go bald!”

Mary watched her teacher intently. She was so soft and bouncy! So…fertile.

Would you like her, my ward?

Mary started at the sound of Rasha’s voice in her mind.

“She’s very pretty.”

I can give her to you, my dear. It fits nicely with my plans for you. Her body is soft and womanly. A perfect playground for you, and her womb is a perfect seedbed.

“Yes, please mistress!”

“Is everything okay, Mary?” Mrs. Greenwood asked.

Mary smiled, “never better!”
