My Yoga Instructor's Huge Cock Claims My Virgin Ass

Emma had been coming to the private evening yoga sessions for six weeks now, telling herself it was for flexibility and stress relief. The real reason was Marcus.

The studio was a converted warehouse loft downtown, all exposed brick and low golden lighting. At 7:30 p.m. every Tuesday and Thursday it was just the two of them. Marcus was twenty-eight, six-three, carved from muscle and sun-browned skin. He never wore a shirt during their sessions anymore. Sweat would roll down the deep grooves of his abs and disappear into the waistband of those obscenely tight black compression shorts that did nothing to hide the thick, heavy outline of his cock.

Emma was nineteen, a sophomore with a tight runner’s body, perky B-cups, and an ass she had always considered small until Marcus started adjusting her in downward dog. His big hands would grip her hips, thumbs pressing just inside the waistband of her tiny yoga shorts, and she would feel that fat bulge brush against the back of her thigh. By the end of every class her virgin asshole would be twitching and clenching with a need she didn’t understand.

Tonight the heat in the studio was turned up higher than usual. Sweat poured off both of them. Marcus had her in a deep pigeon stretch, her right leg folded under her while the left stretched back. He knelt behind her, one palm flat on her lower back, the other sliding slowly up her hamstring.

“Deeper, Emma. Open those hips for me.”

His voice was low, rough. She pushed back and felt the unmistakable press of his hardening cock against her left ass cheek. It was huge. She couldn’t stop the tiny whimper that escaped her throat.

Marcus noticed.

When the session ended she stayed on all fours, panting, staring shamelessly at the massive tent in his shorts. The fabric was stretched so tight she could see the flared shape of his cockhead and the thick ridge of his shaft. A dark wet spot had formed where he was leaking.

“Emma,” he said, voice calm but edged with hunger. “You’ve been staring at my dick for weeks. You want to feel it?”

Her face burned. She was still on her hands and knees, ass up, and she couldn’t lie.

“Yes,” she whispered.

He crouched in front of her, tilting her chin up with two fingers. “You ever had anything in this tight little ass before?”

She shook her head, biting her lip. “Never. Not even a finger.”

Something dark and possessive flashed in his eyes. “Good. Then I’m claiming it tonight. Right here on the mat. I’m going to stretch that virgin hole wide open and fuck it until you can’t walk straight.”

Emma’s pussy clenched so hard she felt fresh slick soak her shorts. “Please.”

Marcus stood, hooked his thumbs in his shorts, and shoved them down. His cock sprang free—thick, veined, easily nine inches and so heavy it barely curved upward. The head was swollen and glistening. Emma’s mouth watered.

He peeled her soaked tank top off, then dragged her tiny shorts and thong down her legs in one motion. She was completely naked on the black yoga mat, trembling with anticipation.

Marcus dropped to his knees behind her, spread her ass cheeks with both hands, and dragged his tongue straight up her crack. Emma cried out at the wet heat of it. He licked her asshole in slow, filthy circles, then pointed his tongue and pushed inside her.

“Oh my God,” she gasped, pushing back against his face.

He ate her ass like a starving man—licking, sucking, spearing his tongue deep while two thick fingers found her dripping pussy and fucked her in rhythm. When he replaced his tongue with one slick finger at her asshole, she moaned so loudly it echoed off the brick walls.

“Relax for me, baby. Let it in.”

The finger sank past her tight ring. The stretch burned, but it also lit up every nerve ending she didn’t know she had. He worked her slowly, adding a second finger, scissoring her open while he whispered filthy praise.

“Such a greedy little virgin ass. Look at it sucking my fingers. You’re going to take every inch of my cock, aren’t you?”

“Yes,” she sobbed. “Please, Marcus. I need it. I need your huge cock in my ass.”

He pulled his fingers free, lined up the fat head of his dick, and started pushing.

The first inch felt impossible. Emma’s mouth fell open in a silent scream as her virgin ring stretched obscenely around his girth. He went slow, relentless, feeding her another inch, then another. Sweat dripped from his chest onto her back.

“Fuck, you’re tight,” he growled. “Best ass I’ve ever felt.”

Halfway in she was shaking. He reached under her and found her swollen clit, rubbing tight circles until the burn melted into white-hot pleasure. The last few inches sank in on a long, smooth stroke until his heavy balls rested against her soaked pussy.

Emma had never felt so full in her life. Her asshole fluttered and clenched around the massive intrusion, every throb of his cock sending sparks up her spine.

Marcus gave her ten seconds to adjust, then started fucking her.

Long, deep strokes at first—pulling out until only the head remained trapped inside her stretched ring, then sliding back in until his hips slapped her ass. The wet, obscene sounds of lube and sweat filled the studio. Emma’s arms gave out; she dropped to her elbows, cheek pressed to the mat, ass high in the air like a bitch in heat.

He fucked her harder. The pace turned brutal. Every thrust punched a desperate cry out of her throat.

Then he pulled out completely, flipped her onto her back, grabbed her ankles and folded her in half. The piledriver position left her gaping asshole pointed straight up at him. He slammed back inside in one brutal stroke.

“Oh fuck, Marcus—your cock is so deep!”

He pounded her without mercy, hips hammering down, balls slapping her ass. The angle let him grind against something devastating inside her. Emma’s hand flew to her clit and rubbed frantically.

“I’m gonna come—don’t stop, please don’t stop—”

Her orgasm detonated like a bomb. Her asshole clamped down so hard on his pistoning cock that he groaned like he was in pain. Clear girl-cum sprayed from her untouched pussy, soaking his abs and chest.

Marcus fucked her straight through it, then suddenly yanked out. He flipped her onto her stomach again, straddled her thighs, and stroked his massive, vein-ridged cock. The first thick rope of cum blasted across her stretched, winking asshole. The second and third painted her lower back and the curve of her ass. He kept coming—long, heavy spurts that covered her skin in pearly white.

When he finally finished, he smeared the head of his cock through the mess, pushing some of it back inside her ruined hole.

“On your knees,” he ordered, voice hoarse.

Emma obeyed on shaky limbs. He fed his spent, cum-smeared cock between her lips. She tasted her own ass and his load at the same time, sucking him clean with eager, worshipful strokes of her tongue until he was spotless.

Marcus stroked her hair, then tilted her chin up.

“Next session, I’m bringing lube and a bigger plug. We’re going even deeper. I want this ass trained to take me whenever I want. Understand?”

Emma nodded, eyes glassy with addiction. “Yes, sir.”

She left the studio twenty minutes later walking bow-legged, his cum still slowly leaking from her well-fucked asshole and trickling down the inside of her thigh. Every step sent a filthy reminder through her body.

By the time she reached her car she was already calculating her class schedule, wondering how many private sessions she could book before the weekend. Her sore, stretched hole clenched at the thought of Marcus’s huge cock claiming her again—deeper, harder, maybe even twice in one night.

She smiled, started the engine, and drove home already wet for next time.
