Toby was a young fox boy in a classroom full of hermaphrodite bunny girls. He sat alone, his nose deep in a comic book, when a shadow passed over his pages. Toby looked up to see a bunny girl wearing a tight white tank top with a black bra under it. She was the same age as him but already very well developed. In fact, all the girls had gone through multiple puberties. Many were thick and musky, their fur soaked in sweat all the time. They didn't have any shame or modesty, however, and they wore tight skirts and shorts that showed off their rumps and thighs. Their tops were tight and thin, revealing their nipples and even their hair down below.
The fox boy gulped. "Hi, Jessie," he said, smiling shyly. "How can I help you?"
Jessie's eyes narrowed and she sat on Toby's desk, her butt pushing his comic books aside. She leaned over and grabbed his head, pulling his nose between her cleavage. "You know what I want, Foxy," she growled.
Toby's tail wagged, his cock throbbing in his jeans. The girls were not like the girls back home, and the boys were not like the boys back home. They were all perverted little animals who spent all day and night thinking about sex. Even the teachers were horny hermaphrodites. And so, it wasn't surprising that Jessie, the most dominant girl in the school, had chosen the biggest dicked boy in the class for her own.
Toby's lips moved against her boobs, his tongue reaching out to lick her soft, furry skin. Jessie moaned and let his head go. Toby immediately went for her pussy. He lifted her skirt up, his fingers hooking into her panties. Jessie lifted herself up, and Toby yanked them down to her ankles, and she stepped out of them, spreading her thighs. Her big bunny sheath and balls blocked his view of her pussy.
Jessie pushed Toby's head down and the fox licked at her bulge, his mouth closing around her sheath. He sucked on her cock as it began to slide out. Jessie groaned, her hands moving up and down her body, rubbing her tits. The girls giggled and cheered from the other side of the room, their own pussies and cocks getting wet as they watched the fox pleasure their classmate.
Jessie's cock came out of her sheath, long and thick and veiny. Toby took it into his mouth, sucking on it. Jessie moaned, her cock throbbing inside the fox's mouth. Toby bobbed his head, slurping and gagging on her fat prick.
Jessie pulled Toby off her dick, saliva dripping down his chin. The rabbit grabbed him and stood up, turning around. She bent over the desk and pulled her skirt up, her plump bunny cheeks exposed to Toby's face. Her asshole and pussy were dripping wet, begging for attention.
Toby got behind her and took his cock out. It was a nice, big fox dick. He pressed his cock against Jessie's ass, and then slipped it inside her. Jessie moaned as Toby's dick spread her ass open, her cock and balls throbbing. Toby began to thrust into her, his paws on her hips, holding her steady as he fucked her. Jessie's eyes rolled back, her tongue lolling out of her mouth as she was railed. Her tits jiggled in her tank top, her nipples hard and poking through the fabric.
Toby leaned over, his hands wrapping around Jessie's body, his fingers gripping her breasts, squeezing them. Jessie moaned and arched her back, her ass smashing against Toby's groin. His knot popped inside her ass, locking the two together.
The fox came, filling the rabbit's ass with his hot, gooey seed. Jessie's eyes crossed, her tongue sticking out of her mouth. She came too, her pussy spraying girlcum all over the desk and floor, her balls pulsating as her cock squirted.
After they both orgasm, Jessie and Toby felt puberty push through them both. The two of them became bigger, thicker, their muscles bulging, their balls and tits growing larger. Jessie's belly grew swollen with babies, the eggs in her womb fertilized by Toby's potent seed.
The two panted and gasped, looking at the class of bunny girls, their faces red and flushed. The teacher stood in front of the class, her hand on her dick, stroking it as she looked at the two, smiling. "That was wonderful, you two. Class, take notes on how these two did it, because you're going to be doing the same thing very soon..."
The youngest bunny girl in class, a six year old with a little baby bump in her belly, began to moan. A cock slid out of her sheath, her first cock. She reached down and grabbed it, squeezing it. Her belly began to grow, along with the rest of her. Puberty had come to the classroom.
Toby and Jessie's bodies continued to change, to get bigger. Jessie's belly became massive and swollen. It seemed she was carrying several litters. Toby's balls were huge, like big oranges.
Toby began to thrust again, and he slammed his cock inside Jessie's pussy this time, the rabbit gasping. Jessie moaned, her ass shaking. Toby's knot swelled inside her pussy, locking them together, and he began to dump more and more of his hot cum into her. Jessie's stomach swelled, her belly becoming even bigger, her womb filled with more and more litters.
