Anatomy 101 - Part 3

The third day felt inevitable.

By now the routine was almost ritual. Alex walked into the classroom knowing exactly what would happen. No one even pretended surprise when Hargrove’s eyes landed on him the moment the door closed.

“Mr. Carter. Front. Platform. Undress.”

Alex stripped without a word. Shirt, trousers, briefs—everything folded, set aside. Naked again, skin still faintly marked from yesterday’s handling, cock already lifting at the memory of James’s finger. He climbed onto the table, this time positioned on all fours: knees spread, back arched slightly, ass presented. A small stack of towels had been placed under his hips. The projector screen now displayed a simple anatomical diagram labelled “Penile-Vaginal / Penile-Anal Intercourse,” but no one was looking at it.

Hargrove addressed the class with the same detached authority.

“Today: sexual intercourse, with emphasis on anal penetration. To demonstrate mechanics, lubrication, sphincter response, and ejaculation inside the rectum. It would be impractical—and medically inadvisable—for the entire class to participate.

Therefore, ten boys have been randomly selected via the class register.”

He read the names from a slip of paper.

Eight were ordinary classmates—boys Alex sat near, passed notes with, shared lunch with. They looked equal parts nervous and eager.

The ninth name made Alex’s stomach clench.

“Tyler Grayson.”

Tyler—the tall, loud one who’d spent the last two years shoving Alex into lockers, mocking his quietness, calling him “pretty boy” in the halls. Tyler grinned now, slow and mean, cracking his knuckles like he was warming up for a fight.

The tenth name was last.

“James Whitaker.”

James didn’t react outwardly. He just pushed off the wall where he’d been leaning, eyes locked on Alex, and moved to join the line forming at the side of the platform.

Hargrove continued. “Each participant will wear a condom for hygiene. Lubricant provided. Penetration should be controlled. Ejaculation inside the rectum is permitted and will be observed for demonstration of post-coital seminal retention and prostate stimulation effects.”

Condoms and lube packets were passed out. The first eight went in order.

Boy one was gentle—almost too gentle—sliding in slow, gasping at the heat, coming within two minutes with a quiet grunt.

Boy two lasted longer, shallow thrusts, whispering apologies every time Alex winced.

Boy three went deeper, found a rhythm, made Alex moan despite himself.

By boy five, Alex was loose, slick, dripping—pre-cum stringing from his untouched cock to the towel below. His arms shook. His hole fluttered around each new intrusion.

Boy seven fucked him steadily, murmuring “fuck, you feel good” under his breath until he buried deep and pulsed.

Boy eight came fast, hips stuttering, adding to the warm, slippery mess inside.

Then Tyler.

Tyler didn’t bother with slowness. He rolled the condom on, lubed himself roughly, lined up, and slammed in—hard, one brutal thrust that punched the air out of Alex’s lungs. Alex cried out, loud and raw. Tyler laughed low in his throat.

“Always knew you’d take it like a bitch,” he muttered, just loud enough for the front row to hear.

He fucked viciously—short, punishing strokes, hips snapping, one hand gripping Alex’s hip hard enough to bruise, the other yanking Alex’s hair back so everyone could see his flushed face, his open mouth, the tears pricking his eyes. Tyler didn’t care about rhythm or pleasure; he just chased his own release, grunting like an animal. When he came, he ground in deep, hips jerking, filling the condom while Alex whimpered beneath him.

Tyler pulled out abruptly, slapped Alex’s ass once—hard—and stepped back, smirking. “Next.”

The room was thick with heavy breathing, the wet sounds of latex and lube, the faint musk of sex.

Then James.

James stepped forward last. He rolled the condom on slowly, eyes never leaving Alex’s face. He slicked himself generously—thick, uncut, veined, the foreskin already retracted over a blunt, flushed head. Even soft it had been impressive; hard, it looked obscene—longer and girtier than any of the others, curving upward just enough.

He moved behind Alex, hands gentle on his hips where Tyler had left red marks. He rubbed slow circles with his thumbs, soothing.

“You okay?” James murmured, so quiet only Alex could hear.

Alex nodded, throat too tight to speak.

James pressed forward—not thrusting, gliding. The stretch was fuller, deeper, but slower. He sank in inch by inch until his hips met Alex’s ass, buried to the root. Alex’s back bowed; a long, shuddering moan spilled out.

James didn’t piston. He rocked—slow, rolling thrusts that dragged over Alex’s prostate with every pass. One hand slid up Alex’s spine, between his shoulder blades, pressing him down gently so his chest rested on the table, ass higher. The other hand wrapped loosely around Alex’s leaking cock—not stroking, just holding, warm palm cradling him.

James fucked like he was making love.

Deep, deliberate rolls of his hips. Long, languid drags out, then smooth slides back in. Every stroke angled perfectly, grinding against that swollen gland until Alex was trembling, babbling soft, broken sounds. James leaned over him, chest to back, lips brushing Alex’s ear.

“Let me feel you come,” he whispered. “Just like this.”

Alex shattered.

No hands on his cock—James never stroked—just the relentless pressure inside, the heat, the stretch, the way James’s thick length filled him completely. Alex came with a choked sob, spurting hard onto the towel, hole clenching rhythmically around James’s cock. The contractions pulled James over the edge.

James groaned—low, wrecked—hips stuttering once, twice, then burying deep as he came. Alex could feel it: the pulse, the heat blooming inside the condom, the way James’s cock throbbed against his walls with every spurt.

They stayed locked together for a long moment. James’s arms came around Alex’s waist, holding him steady while his breathing slowed. When he finally pulled out—careful, gentle—Alex felt empty, tender, dripping despite the condom.

James stripped the condom off, tied it, dropped it in the bin. Then he helped Alex sit up, one arm around his shoulders, steadying him as the class watched in stunned silence.

Hargrove cleared his throat.

“Note the difference in response when penetration is paced and considerate. Prostate stimulation combined with emotional connection can produce significantly more intense orgasmic contractions.”

Alex leaned into James’s side, still shaking, cum drying on his stomach, thighs slick. James didn’t let go.

The bell rang.

No one moved for several seconds.

Then, slowly, the boys began to file out—quiet, subdued, glancing back at the two still on the platform.

James waited until the room was nearly empty.

He pressed a soft kiss to Alex’s temple.

“Tomorrow?” he asked quietly.

Alex swallowed, voice hoarse.

“Yeah.”

James smiled—small, real—and helped him down from the table.

For the first time in three days, Alex didn’t feel humiliated.

He felt wanted.
