"No, please!" Mary shouted as John stepped forward, a small bottle of blue liquid in his hand. "You can't make me drink it!"

"Don't you want to become a sex goddess? That should please both of us very much." John said, moving closer to Mary. She was only a young girl of 17, very beautiful. She wore a thin white night gown, as she had been disturbed from her sleep by John. She knew that if she didn't drink the potion, John would rape her again, and force the liquid down her throat. Still, she did not want to become a huge breasted whore.

"No. . . I will not mutilate my own body!"

"Then I shall do it for you." John lept at Mary, who screamed and fell backwards onto the floor. With one hand on Mary's chest, he popped the cork off of the bottle, and moved it toward her face. "Open your mouth," he said, pushing on her breasts. Mary did as he ordered, and John poured all of the liquid in. Mary had a plan, however, and so she swallowed only half of the precious liquid, storing the rest in her mouth. She raised her hands and pulled John in, closer, for a kiss. Although he thought it odd, John put his mouth to Mary's, and inserted his tongue. Immediately, Mary rolled over onto John, and spat the liquid into his mouth, then pinching John's nose with one hand, and closing his mouth with her other. She held him to the ground, her legs spread apart, John's hard dick pushing through their clothing, into her pussy. John swallowed. He then threw Mary off, stood up and shouted, "You bitch! This formula is for females! It may kill me!"

"I hope you die!" Mary yelled, backing into a corner.

"I'll take you with me!" But just as John said that, a blank look washed over Mary's face.

"Wh-what's happening to.. me?" she mumbled. As the potion took effect, her body began to change. Mary's tits swelled under her night gown, and she began to cry. Slowly, but at a steady pace, her chest expanded outward, soon stretching her once loose clothes. Her nipples, about an inch wide, could be seen through the tight fabric. John placed a hand on his swollen member, noticing that it was a bit softer than before. He took off his pants, tore off his shirt, and stepped closer to Mary, who's gown looked as if it was about to split open from the pressure. Surely enough, there was a tearing sound, and her massive breasts lunged forward.  The growth stopped, as did Mary's crying. Suddenly she stood up, a determined look on her face. John was startled, but advanced towards her none the less.

"Take me, John." Mary said in an unusually lustfull voice. He reached for her hips so that he could pull off the rest of her ripped night gown, but before he could reach forward, Mary let out a cute scream, and a smile came across her face. "I'm growing again..."

"Y-you are?" John stuttered. He couldn't believe that her breasts had grown that large, how could they get any bigger? He stared at them for a moment.

"No, lover, not there... Down here." She pointed to her rear, and let out a small laugh. John's eyes grew wide as he saw Mary's gown become increasingly tight around the hips. As her ass expanded, the cloth grew thinner. Soon, the final piece of night gown clinging to her body ripped and fell to the ground. She was truely a goddess, now. Her hips were wide, her butt was large, yet firm and appealing, and her tits were unbelieveable. John couldn't wait to do her. The two stepped closer, and John thrust his loin at Mary's, but his penis didn't go in. A startled look came over Mary's face, and she looked down, but couldn't see over her monsterous boobs. John stepped backward, looking down to find that it was missing. In its place was a small, hairless, pre-pubescent pussy. He screamed, but his voice was high and shrill.

"My God! I'm changing, too!" He said in a child's voice. Slowly he shrank down into what looked like the body of a very thin, short 8 year old girl. He fell to the floor and started to cry. Mary smiled and walked over to the nude girl, who was curled up on the floor, still bawling.

"It'll be okay, honey. But I want you to lick my pussy, I'm so horny!" Mary said, taking the childs hand and placing it to her clitoris.

"No!" The child screamed, standing up and running to the far side of the room.

"Come here, little one. Do not be afraid!" Mary said, smiling. John placed one hand over his vagina, and the other over one of his breasts, trying to save his dignity.  He couldn't think straight. Suddenly, an image of he and Mary having lesbian sex came into his head. He threw his hands back against the wall, almost involentarily.  Mary watched as John's second transformation took place.

He, or perhaps now a she, began to moan. John no longer looked 8, but now about 12. His eyes closed, and he rocked back and forth. He grew taller, his legs shaping into those of the most beautiful teen. While his hips widened, blonde pubic hair formed around his pussy, and a clit began to protrude from the top of it, juices oozing out. His ass became round and rock solid, his breasts following. They ballooned out at an amazing rate, stopping at around a DD cup. Throughout this, his face matured into that of a beautiful 16 year old girl.

The lustful energy between John and Mary was so strong that they practically leapt onto each other. The two made love all night, happy with their new forms.  Happy until Mary's father found out, that is. They were both hanged for witchcraft, for it was unheard of for someone's breasts to magically grow, or for a man to become a girl. It doesn't seem all that odd, does it?
