Once upon a time there was boy named Dennis ...

"How do you like that?" he asked.

"Oh, yes, please, more," Annie sighed, sucking in her breath from the excruciating pleasure he was bringing her.

He moved his fingers back and forth inside her, like a small child walking with his fingers. Annie closed her eyes and pumped her loins upward. Her cunny was tight, but it flowered open as his probing fingers excited her to greater heights.

"Please," she murmured, tiny beads of sweat forming on her forehead. "Take me now, honey, please! I can't stand it any more!" Her cries excited him. His gorgeous young blonde mother underneath him was all that he wanted. Her desires were so urgent, and he was only too happy to meet them. He guided his massive cock between her wide-spread legs. He probed for a moment, teasing the soft lips and feeling the wet flesh beneath it open wider.

"Oooooooooooh, ooooooooh ... " she moaned as she felt the familiar huge head slip inside her, worming slowly into her passage and filling her with all the hardened flesh she could stand.

Doing it outdoors was one of their favorite kinks; the possibility of discovery added spice to their lovemaking. Outside the car it was pitch-black above the city lights below, but inside the white convertible bright flashes of sexual heat electrified the air. She thrashed her head from side to side. "Oh more, more!" she cried aloud, locking her legs open wider to take him as deep as she could.

He began to stroke slowly in and out. Out for an inch or two, then slipping wetly back inside. He wanted this to last. Annie groaned and lifted her knees higher. Her ass strained up off the seat, her throbbing cunny reaching hungrily up for the white hot rod of flesh as it began to increase its pitch. She settled into the rhythm, meeting his driving pelvis with upward jerks.

Her insides were about to burst. With each stroke the brilliant strobe-like flashes in her mind intensified. She thrust upward, harder and harder, trying to fill herself completely with him. His huge she-male boobs rubbed and crushed her own big tits until their nipples were raw and hard.

She dug her nails into his full rounded asscheeks. Even in her wild fury everything was slow motion. Each second seemed like a minute. The muscles in her belly responded to the call of her clasping butt. The time was coming!

A great wave welled up inside her. It started lazily, far down in the depths of her quivering belly and rolled downward like the sea with increasing power until it hit the bottom of her grinding pelvis at her opening, crashing against her just as his pelvic bone crushed into her. The next came faster, snapping like a whip. She screamed, "Aaarrrggghhhh! Now! God, I'm cumming now, oh, oh, I'm cummmmmmiiiiinnnnng!!"

She jerked up as her entire being seemed to snap. Again and again the waves of orgasm crashed against the cliffs of her soul as she rebounded with them, jerking upward again and again. Her orgasmic juices filled her desperately sucking vaginal passage, lubricating it more and more.

Her volcanic climax brought him to his own end. Like a lithesome animal he rose up, throwing his long red hair in circles to the side. The pressure in his balls burst as the hot fluids erupted out through his straining tubes and spurted from his reddened cock deep into her open cunt. She was still cumming when she felt his juices hotly filling her belly, adding more wood to the fire. "Oh. OOOOooh, perfect, Oooooh!" she cried out, her head rolling helplessly from side to side on the squeaking car seat.

Completely spent, he fell on top of her. Her eyes were closed, her legs dropping limply to her sides, and a broad satisfied smile spread across her face. The moment of remembrance, of savoring the moment now occupied him.

His thoughts wandered back to not much more than a year earlier, when he'd been a normal boy; before he'd become a lusty redheaded she-male with 36-D boobs, a tiny waist and a round ass ...

Worst of all, Dennis' best friend Debbie was obviously developing a crush on his Dad. She spent all her free-time at his house these days and she was always flirting with the old man. And sometimes his Dad flirted back! Dennis and Debbie had been friends since they were 2 years old, but Dennis ached to be more than friends with the blonde cheerleader with a tight curvy body. But she never thought of Dennis as anything but a buddy. Dennis knew he wasn't good-looking enough for Debbie, so he begged his Dad to give him the DNA serum, but his father refused. It was undergoing more tests.

So Dennis was mad. And jealous.

Dennis visited his Dad's lab and stole two vials of serum when nobody was looking. He drank both vials, thinking that if one dose was good, then two would be better. What Dennis didn't know was that one of the vials contained a serum formula that was incomplete, and would only effect the male sexual organs. The second vial did contain a complete and effective "perfect body" serum -- but it was for a woman.

In calculus class his voice cracked in the middle of an answer which broke up the whole class including the teacher. Dennis blushed but he recovered quickly. Nothing happened the next day but on Wednesday as he stepped out of the shower in the locker room, his chest felt sore. And swollen. He could actually feel loose flesh around his nipples. He put it out of his mind but the next morning, alone in the bathroom, he examined himself in the mirror. Not only was his chest swollen but the nipples were larger. They looked like small pegs. The circles around them had turned a deep, reddish brown and were enlarged as well. "That serum does some strange shit while it's molding the perfect body," he thought as beads of sweat broke out on his brow. He didn't notice that he didn't need to shave. He buried his fears, dressed and rushed to school.

He cut gym that day and went to the library. Pouring over a fat medical textbook he could find nothing that would account for the swelling in his chest.

After school he met his swim team buddy Jim in the hall. "Aren't you going to practice?" he asked.

Dennis turned red. "No, I can't today."

"Why not?"

"I have to get a haircut."

"That's a lame excuse. Coach'll be pissed. You okay? You don't look so hot."

"I'm fine," Dennis said, walking toward his locker.

"Gained some weight in your butt, dude," Jim called after him. Dennis instinctively put his hands on his buttocks and Jim's laughter echoed down the hall.

Jim was right, Dennis thought, "Well, I wanted my body to change."

He walked home, so engrossed in contemplation that when Debbie called out to him, he just kept on walking. "Hey, didn't you hear me?"

"What, oh, hi."

"Is something wrong Dennis?"

"No, nothing's wrong," he said, his voice cracking.

"You've been doing that a lot lately, are you going through reverse puberty or something?"

"Look nothing's wrong, okay?" Just as he reached the last syllable it cracked again and Debbie suppressed her laughter because the look in his eye was murderous. "Look I've got to get a haircut now. I'll see you tomorrow," he said trying hard not to let his voice crack again.

"Sure. Call me. Bye." He ran off toward the mall.

When he finally got home, he raced to the bathroom and stripped off his shirt. His hands felt his chest. The firm swelling flesh reached out into space about an inch. The nipples were larger and the aureoles were now three inches across and reddish brown. He could never go back to the swim team now. Not like this. He stood for a moment wondering if he should tell his parents when he noticed his hair. He'd just gotten it cut and it was over his ears again. Then he noticed his cheeks were devoid of even the peach fuzz stubble that grew between shaves. Instead they were smooth and pink.

At dinner he wore a bulky sweater to hide his swelling chest. No one seemed to notice and afterwards he went to his room and shut the door. Around nine his mom knocked to say good night. He sat at his desk pretending to study. "Everything all right, honey?"

"Yeah, sure. Why?"

"No reason. Hey, will you promise me to get your hair cut tomorrow?" she said as she closed the door. The next day at school his voice cracked so many times that he stopped talking altogether. On the way home, Debbie knew something was wrong.

"What the matter with you lately, Dennis? You're so sulky and weird."

"Nothing's the matter. I've just been studying really hard." His voice cracked midway through the sentence and stayed in the upper register. "Debbie, can I tell you something?"

"Sure, Dennis. What is it?" He blurted out the story of how he'd stolen the vials and all the strange changes that were taking place in his body.

"I want to see," she said. They ran to her house and Debbie pulled him up the stairs. When they were alone in her room she said, "Well, take your shirt off."

"Promise you won't laugh," he said.

"I won't. Just take your shirt off and show me." Dennis unbuttoned his shirt slowly and then peeled off his T-shirt. He couldn't look at her.

She said nothing but her silence spoke volumes. "What's wrong with me, Debbie?" Her eyes were traveling down from Dennis' chest to his waist. "Dennis, take off your pants too."

"Why?"

"Just do it, okay?" He kicked his tennis shoes off and dropped his jeans. Debbie gasped. "Oh, my God."

"What? What is it?" he yelled.

"Your, uh, your butt."

"What about it?"

"It's bigger too," she said haltingly. "Look!" she said, opening the door to her closet and pointing at the full length mirror. Dennis looked over his shoulder into the mirror and for the first time all the puzzle pieces in place fell into place. His jockey shorts were stretched tightly over his bottom and he knew instantly why none of his pants seemed to fit anymore. His waist had narrowed as well. "You look kind of ... like a ..."

"Like a what?" his voice cracked.

"Like a girl."

"What do you mean?"

"I mean, your body looks ... well, rounder and softer. What about down there?" she said, pointing to Dennis's groin.

"It's the same. If anything it's bigger. Touch it," Dennis asked longingly.

"Dennis, no." "Yeah, I understand. We're just friends ..." He quickly got up and went home.
