Tutoring the Bad Boy's Big-Assed Tutor

Selena knocked just after eight, twenty-two and already flushed, textbook pressed to the plain blouse she always wore for tutoring. The ankle-length skirt hid the huge round ass she spent half her life pretending not to notice in mirrors. Franklin opened the apartment door in a gray tee and low sweatpants, twenty-one, athletic, shoulders filling the frame, and looked her over like the modest clothes offended him.

"Church clothes," he said. "Get in."

She stepped inside. Finals notes were stacked on the desk. A wooden ruler lay across them. She set her bag down and tried for calm. "I'm here so you pass. That's the job."

He shut the door and stayed in front of it. "Job changed. I bought you an outfit. Tight. Short. You wear it if you want me focused. Bathroom. Now."

The order hit low in her belly. She should have refused. Instead her nipples tightened under the blouse, and Franklin's mouth curved like he had watched it happen.

"You like being told," he said. "Don't waste my time lying."

"If I change, we study."

"We'll see what that ass does to my attention span."

In the bathroom she found a black skirt that was barely a skirt and a cropped top with thin straps. She stripped, heart hammering, and pulled them on. The skirt clung to her huge ass and stopped high, the hem riding the lower swell of her cheeks so most of it stayed bare. The top strained over her busty chest, breasts barely contained, nipples already hard against the thin fabric. She looked filthy. She looked like his.

When she walked out, Franklin went still. His eyes locked on her tits, then dropped and stayed on the exposed curve of her ass.

"That's what I wanted," he said, voice rough. "Sit. Open the book. Stop pretending we don't both know this is heading somewhere sexual."

She sat. Cool air touched the skin the skirt refused to cover. She was wet, and they both knew it.

Selena opened the chapter and tried to sound like a tutor. "Start with the formulas on page forty. If you miss the setup, the whole problem collapses."

Franklin didn't look at the page. He sat across from her, legs spread, and watched the cropped top fight her tits every time she breathed. The skirt had ridden so high that the underside of her huge ass showed against the chair. She shifted, and more skin appeared. His sweatpants did nothing to hide how hard he was getting.

"Franklin. Eyes up. The variable goes here."

"I heard you." His voice had gone low. "I also heard nothing that matters more than that ass."

She kept talking anyway, walking him through the first problem, pencil tapping, trying to ignore the heat between her thighs. Every time she leaned forward the top gaped and her breasts nearly spilled. Every time she sat back the skirt climbed. Franklin's hand rested on his thigh, close to the thick ridge in his pants, and he didn't bother adjusting it.

"Again," she said, a little breathless. "Show me the steps."

He took the pencil, wrote two lines, and dropped it. "I can't concentrate. All I want is to spank that perfect ass until you stop sounding so proper."

The words landed and stayed. Selena's pencil stalled over the page. She had pictured this on the walk over, pictured his hand, pictured herself bent and saying yes. Admitting it out loud made her face burn and her pussy clench.

"I've been fantasizing about it," she said. "About submitting to you. Not as a joke."

Franklin's eyes darkened. "Say it clear."

"I want you to punish me. I want the spanking. I want you in charge of this session." She met his stare, turned on and certain. "Consensual. We stop if either of us says stop. Otherwise you can be as strict as you want."

"Good girl." He pushed the textbook aside and picked up the wooden ruler, testing the weight. "Then this is a tutoring punishment game. Every time you stumble, you get swats. Extra if you come without permission. You wear that tight little outfit the whole time, and you thank me."

"Yes." Her voice shook with want. "Yes, Franklin."

"Over my lap. Now."

She stood on unsteady legs, skirt hiked, and draped herself across his thighs. Her huge ass rose, barely covered, the thin fabric bunched at the top of her cheeks. Franklin shoved the skirt higher until her ass was fully bare, round and soft and waiting. His palm settled on one cheek, heavy, possessive.

"Count when I tell you to. Color?"

"Green," she said. "Please."

The first smack cracked through the apartment. Heat bloomed. The second landed harder, his athletic arm putting real force behind it, and she gasped into the cushion of his leg. He spanked her in a steady rhythm, left cheek, right cheek, the underside where her ass was thickest, each blow jolting her tits against his thigh. The sting built fast. She moaned, hips shifting, and he pinned her with one forearm across her lower back.

"Stay still." His hand came down again, harder, the sound sharp. "This ass was made for it."

He kept going until both cheeks glowed red, the skin hot under his palm. She counted when he demanded it, voice breaking around twenty, then twenty-five, her pussy dripping onto his sweatpants. Franklin paused only to squeeze the punished flesh, spreading her so cool air hit her soaked slit, then resumed until she was whimpering and pushing back for more.

"Hand's too kind," he said. "Ruler."

The wood tapped once, a warning, then snapped across the fullest part of her ass. The sting was brighter, meaner, a thin line of fire. Selena cried out, fingers clutching his pant leg. He gave her a set of sharp strokes, spacing them so each one landed on already reddened skin, the ruler whistling before it struck. Her huge ass bounced with every hit. She was moaning openly now, thighs slick, begging without forming the words.

"Penalty swats," Franklin said. "You showed up in those church clothes and made me wait. Five extra. Hard. Count them."

"One—" The ruler cracked. "Two—ah—three—" She sobbed the numbers, not from pain she wanted to escape but from how good the burn felt. "Four. Five. Thank you."

"Again. You looked at the book instead of me."

Another five. She counted, voice wrecked, ass blazing, and when the last one landed she ground down on his thigh like she might come from the spanking alone.

Franklin tossed the ruler onto the desk. "Up. Bend over it."

She scrambled off his lap, legs shaky, and he spun her, bending her over the desk so her red ass faced him and her tits hung in the strained top. He yanked the cropped fabric down. Her massive breasts spilled free, heavy, nipples tight. He reached around and played with them roughly, squeezing, lifting, pinching the nipples until she yelped and pushed her ass back into his hips.

"These stay out," he said, palming one breast hard enough to make her moan. "Every time I fuck you, I want them in my hands."

He shoved his sweatpants down. His cock was thick, already wet at the tip, and he dragged it through her soaked folds once, twice, then pushed into her pussy in one deep thrust. Selena's mouth fell open. He filled her, stretched her, and didn't give her time to adjust before he started fucking her from behind in long, dominant strokes. The desk creaked. Her huge ass slapped against his hips, the spanked skin stinging every time he bottomed out.

"Franklin—harder—"

"You don't give orders." He grabbed a handful of her hair and pulled, arching her back, and fucked her deeper. His other hand stayed on her tits, roughly squeezing, thumbs working her nipples while his cock drove into her. "You take it."

She took it. Each thrust shoved a broken sound out of her. He alternated without warning: a sharp spank to her red ass, then a yank of her hair, then both hands on her breasts, mauling them while he pounded her pussy. The ruler was within reach. He picked it up and delivered three quick stinging strokes across her cheeks without pulling out, the wood cracking while his cock stayed buried, and she nearly came on the spot.

"Please," she begged. "Please, more. Spank me and fuck me. Don't stop."

"Greedy little tutor." He dropped the ruler and used his hand again, spanking her in time with his thrusts, the impacts making her clench around him. "Listen to that ass. Listen to how wet you are."

The sound was obscene, skin on skin, her moans filling the apartment. He leaned over her, chest to her back, and fucked her in short, brutal thrusts that hit deep. One hand fisted her hair. The other slid under her and squeezed her tits together, pinching both nipples while he used her. Selena begged for every bit of it, voice gone hoarse, telling him her ass was his, her tits were his, that she wanted the penalty and the ruler and his cock until she couldn't stand.

"You don't come until I say." He spanked her again, hard enough to jolt her forward on the desk, then hauled her back onto his cock by her hair. "Hold it."

She tried. Her thighs shook. He played with her breasts like he owned them, rough squeezes, sharp pinches, his hips never slowing. When she whimpered that she was close, he gave her two more penalty swats with his bare hand, right on the sorest part of her ass, and ordered her to thank him.

"Thank you—thank you—please let me come—"

"Now." He slammed deep and stayed there, grinding, one hand crushing her tit, the other pulling her hair so she couldn't look away from the wall. "Come on my cock."

Selena broke. Her pussy clamped down and pulsed, a hard, shaking orgasm that ripped a shout out of her. Franklin groaned, fucked her through it in deep strokes, and followed, spilling inside her in thick pulses, filling her while she kept cumming around him, milking every drop.

He didn't pull out until he was finished. Cum leaked down her thigh the second he slipped free. He tugged the tiny skirt back into place over her blazing ass, left her tits out of the ruined top, and dropped into the chair. "Outfit stays on. Sit."

Selena lowered herself onto his lap, sore spanked ass pressed to his thighs, his cum still dripping out of her. The burn made her hiss. Franklin's hand settled on her breast again, possessive, squeezing while she squirmed.

"Next session is stricter," he said. "More ruler. More penalty swats. You walk in already wearing this, or I spank you before we even open the book."

She smiled, wrecked and satisfied, and ground her tender ass against him. "Yes, sir."

He pinched her nipple hard and spoke against her ear, filthy and final. "Good. Next time I fuck this sloppy, cum-filled cunt over the desk until you're sobbing and that huge red ass can't take another swat."
