-Classroom-

The brunette opened the door and entered the classroom with her sister, just before the bell rang for today's lesson, she could see the teacher Gary at the front of the room behind the desk and whiteboard, she glanced at the desks and saw the other students which were strange since they'd usually be five minutes late.

Ib took her seat and Mary did as well, which was always next to her, she was always infatuated with her sister, though the red-eyed girl never knew why.

"Hello, class, today we have a special lesson in biology, but to proceed I'll need the special permission slip from all of you, I hope you didn't forget to show it to your parents."

Ib glanced at Mary, who fished it out of her pocket, thankfully she held onto her sisters otherwise they'd have missed this special lesson, Ib didn't know what it was since it had hard to read words, and when she asked her parents what it meant they assured her she'd know what it's about before they handed it back signed.

With a hop and skip Mary went up to the desk and placed the permission slips it on the table.

"Thank you, Mary, anyone else?" Gary watched as the boys placed the slips on his desk, all of them got their parents approval, which was perfect since he didn't want any of his students to miss out on an extremely important lesson for their education, Ib could've sworn she saw a grin on his face when he sorted the slips on his desk.

"Alright, now, let's get started." He walked to the door and locked it shut before he stood back at the desk. "Alright Ib, come up here." The brunette pushed back her chair and got up from her seat before she pushed it under her desk, she then walked up to the front and faced the classroom.

Gary then stood beside her. "Now Ib, I'd like you to strip all your clothes off." Which made her a bit confused and embarrassed, she'd be naked in front of the entire class. "Dear, this is for the lesson, there's no need to be shy, you're only showing your natural skin after all." He winked at her.

With that said. the brunette nodded and grabbed her red skirt before she pulled it down slowly, once it was on the ground, her classmates could see her white panties in full display and her slim smooth legs, that bit of exposed skin was enough to make the teacher hard. "Now, your shirt."

She undid her red bow and let it fall onto the floor before she grabbed her shirt and pulled it up and discarded the top where her skirt and ribbon was. Since she hadn't hit puberty yet so her chest had small mounds, and on those mounds were flat nipples.

"And now your panties sweetie, which is underwear for girls." This was eye candy for him, the way she took her time to undress was a major turn-on for him.

Ib bit her lower lip and pulled that down as well, past her long black socks that went up to her knees. She wasn't sure if it was her imagination, but the boys seemed to lean on their desk further as if to get a closer look at the more articles of clothing she removed from her body. Her small closed slit was exposed to the classroom, she covered her pussy and chest when she was done, the only thing that covered her was the socks and that barely covered enough skin.

Mary's seen her naked a thousand times, but this time it was different, the air around her was strange even though she's still in the same room, maybe it's the bashful reactions the brunette made, she's never shown that to her until now since usually, she was stoic, even at her ninth birthday the most she'd show was a smile, now she was the most expressive she's ever been.

"Good dear~" He knelt down and rubbed Ib's head and stroked it like he'd pet a cat. "Pay attention class, because this is important information for baby-making." When Ib heard that she covered her red cheeks.

His right-hand caress from her chest all the way down to her crotch, he spread the closed slit to open her pussy which made the brunette moan softly, a noise which she never knew existed, "Now, this is known as the pussy, that's where the man's penis also known as the cock, penetrates."

"It slides in and out, and once the man feels really good, he'll shoot his white semen inside her, which will get her pregnant, months later her belly will grow bigger and then the baby will come out of the very same hole." His fingers circled on her pussy lips while he gave his explanation. "Yes, you there."

The boy put his hand down. "What if I don't want to make a baby?"

"Good question, you use birth control or condoms, both if you want to be extra sure, but for this demonstration, we'll do neither." He got back on topic.

"Now, we don't want to instantly get into the sex, we have to make her excited and horny first." He used her hands to rub Ib's flat nipples, this made her pant softly as it slowly hardened. "As you can see she's turned on, but we're not done yet." The adult licked it both as if to taste test it. "Mmmm, see how she's now fully wet?" He spread her pussy for the second time before to show that it was very wet.
"Now, class, you can see her vagina is wet, which means your cock will slide in more easily than if you were to push it in dry." The way he touched and caressed her exposed skin made her feel something she's never felt before, her body was hotter and her mind jumbled from the new sensation that ran through her body.

He then unzipped his pants and pulled his cock. "But before we start we need to get this lubed up, how? Easy, she just has to lick it can you do that dear?"

His musky smell hit Ib and she became wetter. "O-oh...Yeah." She looked at his hard large meat and hesitated.

He stroked her head and pushed her face close to his meat. "Now, lick it as you would with a lollypop~"

She got on her knees and slowly pressed her lips against the tip and gave it a few small licks, it tasted like nothing she had before, the way it twitched encouraged her to lick it all over. "Mmmm, just like that sweetie~ Ohhh~"

"All over dear, make it wet so I can penetrate you~ Ahh~ Yes dear you're a natural at this~ Now say ahhh." Ib did what he said and he pushed his shaft into her small wet and warm mouth. "Oh, dear~ This feels better than expected~"

The girl breathed on his shaft as he pushed it in and out. "Now class, this is oral sex, also known as a blow-job, not as good as the real hole, but you can do, ngh...Now dear, watch the teeth, what was I saying? Oh yes, you can do this~" Gary placed his hands on her head and guided her further down to deepthroat it fully. "Now be careful since you might cut off her airway, but in this case, I think I might cum before she passes out~"

Ib coughed and sputtered on his shaft as her throat bulged since he was balls deep. "Mmmmph…!" Without air, her lungs began to burn up and her chest heaved in and out to show that she was desperate to breathe.

"Hang in there sweetie, I'm about to-!" His cock warmed up and he blew his thick white load down her throat to force her to swallow his semen when he pulled out Ib held her throat, gasped and coughed since she was finally able to breathe.

"Mmm, this isn't over sweetie, now if you would be a dear and bend over on my desk." Gary waited for her to do so, once she got enough oxygen she stood up and leaned on the desk, her small behind faced Gary who was still hard.

"This might hurt, you'll have to brace yourself." He warned before he grabbed her hips and penetrated her pussy slowly. "So...Tight~" He couldn't hold it anymore and slammed it all balls deep, he didn't care that he popped her cherry or that there was a bulge in her belly, the moment he pushed into that loli pussy was the moment he lost self-control.

Ib winced and gasped in pain, she's never felt anything like this, the way it stung made her tear up, It was impossible to think about that because he'd immediately pound her like a toy, or more accurately a doll.

"Oh yeah, you're a dirty girl huh?" He slapped her ass which made her yelp. "Your wombs squeezing me so tight~!"

Ib couldn't talk back, her mind wouldn't allow her to process a thought while he destroyed her small vagina and forced it to take his shape. "Now, I think you can try for yourself with Mary, give it a try~ There will be a test on this later~"

He played with the brunette's long smooth hair, ever since he saw her in class he's dreamt of this day, now that he's the one with her he felt as if it can't get better than this, his princess will be his forever and ever.

While he pounded Ib like a flesh-light Mary found herself surrounded by the boys, and with a nervous chuckle, she glanced at them. "Oh um...Nice weather?" She was suddenly grabbed and placed on the desk with her uniform torn off. "Wait! Not so suddenly!" She held her legs spread and her uniform torn off, all around her were horny boys with hard cocks.

Ib's eyes rolled up as Gary continued to pound her, each thrust got him closer to his climax. "I think I'm gonna…~" He grunts and poured his hot thick semen into her small womb, a lot of it spilled onto the ground and made a white puddle. When he slowly pulled out the brunette fell on her side and twitched from the overload of pleasure.

While that happened Mary winced when one of them had popped her cherry, now she knew why her sister made a painful expression when Gary first entered her, the other boys were impatient and forced her to rub their shafts, one of them pushed their cock in her mouth and forced her to suck it, they would take turns with each other, the one that creampies her pussy would swap the one that face fucked her and so on.

The blonde girl twitched after they had emptied their balls, the classroom had the lingering smell of sex in the air as the kids panted heavily to catch their breath after the orgy.

Months later Ib and Mary developed baby bumps and had to show it for biology class so Gary could give the class a physical example of what a girls belly looks like after the fetus in them grew.
