It was a typical day at Chiba Middle School when Haruto first laid eyes on the new transfer student, Rebecca. She was a few years older than most of the other students, with a curvy figure, ample chest and big, juicy ass. Rebecca had a bold, fiery personality to match her pink-dyed hair. She dressed in edgy outfits - torn tights, short skirts, heavy metal band t-shirts. She looked like she belonged in a tough punk gang, not in a ordinary Japanese school.
Haruto couldn't help but stare as Rebecca sauntered into class, swaying her wide hips. There was something about her attitude, her confidence, that drew him in. He felt his pants tighten as dirty thoughts crept into his mind.
After school let out, Haruto lingered by his desk, pretending to organize his backpack. He was hoping to catch a closer glimpse of the attractive transfer girl. As if sensing his gaze, Rebecca looked up from her phone and locked eyes with him. A mischievous smile played across her lips. She beckoned him over with a crooked finger.
"Hey Haruto, come here for a sec," she called out in a low, husky voice. Haruto gulped and made his way to her desk, heart pounding. The other students filed out of the classroom, leaving them alone.
Rebecca leaned back in her chair, one hand resting on a thick thigh. "I've been watching you too, you know. I think you're cute. And I have a feeling you like me..." She patted her lap invitingly. "Why don't you come sit with me and we'll get to know each other better?"
Haruto swallowed hard, his face flushing. But he couldn't resist her forwardness. He perched on her thighs, straddling her under the desk. Rebecca wrapped her arms around his waist and pulled him close, so he could feel the heat of her body. "Mmm, not bad," she purred, giving his ass a squeeze. "So what kind of things do you like to do for fun, Haruto?"
"N-not much, I'm pretty boring," Haruto stammered, squirming slightly on her lap. Rebecca chuckled and slid a hand up his shirt, teasing his abs. "Oh I bet you're not boring at all. In fact, I think you've got a little dominant side, don't you Haruto? I can tell..."
She punctuated her words by reaching around to smack his ass, hard. Haruto yelped and went rigid. Rebecca just laughed and did it again, squeezing the reddening flesh. "Ahh, I knew it! You like it rough, don't you? Naughty boy..." Her other hand slid down to grope his manhood through his pants.
Haruto's resistance crumbled at her touch. He bucked into her palm as she stroked him. "You're so hard already," Rebecca cooed. "There's a bad boy hiding in a good boy package, huh? Don't worry, I can bring him out to play..."
She abruptly shoved Haruto off her lap. He stumbled, but then Rebecca bent over the desk, hiking up her skirt. Haruto stared at the globes of her ass, barely covered by a pink thong. His cock throbbed, fully erect now.
"Spank me," Rebecca commanded, wiggling her butt. "Go on, slap my ass! I can tell you're dying to!"
Haruto didn't need to be told twice. He raised a hand and brought it down on her right cheek with a resounding smack. Rebecca cried out, but it sounded more like pleasure than pain. "Yes, just like that! More!"
Emboldened, Haruto began spanking her in earnest, alternating cheeks, watching in awe as they jiggled and turned pink. Rebecca moaned and writhed on the desk, pushing her ass back for more. Her pussy was dripping wet, leaving a spot on the floor.
Soon, Haruto couldn't hold back any longer. He needed to be inside her. He yanked her thong aside and pressed his bare cock against Rebecca's tight asshole. "You're going to take it all the way up your ass, slut," he growled, relishing her wide-eyed shock. "No lube, no preparation. I'm going to wreck this hole..."
With that, he thrust into her, burying himself to the hilt. Rebecca screamed, but then dissolved into whorish moans as he began pounding her hard and fast. The desk creaked ominously under them as Haruto dominated the older girl, feeling her inner walls clenching around him. He spanked her raw ass with each stroke, making her yelp and push back for more.
It was a brutal, animalistic fucking, the kind Haruto never knew he had in him. But Rebecca took it like a champ, egging him on. "Harder! Deeper! Ruin my ass, you dirty fucking boy! I'm your bitch!"
Haruto lost himself in depravity, lost all sense of propriety and restraint. He hiked up Rebecca's legs, folding her nearly in half, and drilled her even deeper. Her heavy tits swung in his face and he grabbed them, twisting her nipples brutally until she wailed.
Their coupling reached a fever pitch, Haruto slamming into Rebecca's guts with savage abandon. Chair legs scraped against the floor as the desk skidded with the force of his thrusts. Haruto felt his climax building, balls drawing tight. With a bellowing grunt, he buried his cock in Rebecca's ass and exploded, pumping her full of his thick cum.
Seconds later, Rebecca convulsed with a screaming orgasm, her pussy squirting all over the desk. They collapsed together in a sweaty, gasping heap, Haruto still lodged deep in her ass. Rebecca grinned at him over her shoulder, eyes glazed with lust.
"Fuck... that was incredible," she panted. "I knew you had it in you, Haruto. You're a true sadist. I'm addicted to your cock already..."
