“Umm... okay,” Clay murmured, distracted by how close he was to Sam's cock. If he just moved a little lower...

“Get off then and lie down.” Sam startled him by grabbing his waist.

They switched places, Clay laid face down with Sam straddling. The firm weight of Sam pressed Clay's erection into the mattress but not painfully so.

Sam's hands were cold and slippery with oil as they moved over his back. He squeezed Sam's shoulders softly and Clay moaned deeply. It felt strangely comforting; the chill of Sam's hands on his bare skin, the huff of his breath as he leaned low over Clay. The hard press of Sam's cock on Clay's arse became more agitated as he shifted insistently, increasing the rhythm with each thump of his hands.

“Love how it feels?” Sam whispered huskily.

“Feels fantastic,” Clay rasped, the arousal litting his insides. He was trapped by Sam's weight, unable to move to rub himself against the mattress but he could feel the wetness where he was leaking in his underwear, his cock hard and aching.

“You're fucking perfect,” Sam praised, his hands still moving over Clay's skin in slow, thrilling movements, trailing lower. “I love the huge birthmark just below your spine — it's huge.”

“Huge.” Clay chuckled. “Seriously?”

“Relax, it's a compliment,” Sam assured him, rubbing light circles below Clay's spine where the birthmark was. “Huge and beautiful, not like you unfortunately,” he smirked at Clay's offended expression.

“You mean I'm not beautiful?” his voice cracked in anger. “I don't turn you on?”

“Quite an irony, my little master.” Sam grinned. “You're beyond beautiful and you turn me on with your cute smile.”

“I hate my smile. I feel like I go overboard with it sometimes.”

“No you don't,” Sam's hands moved dangerously lower once more. “Your smile makes me want to rip your clothes, hop on top of you and fuck you harder than I'd ever done with anyone before.”

“Sam,” Clay moaned, the effect of Sam's crude words hurting his cock the more. Sam spanned the small of Clay's back as he dug his thumbs in the muscles there. Clay smiled into the pillow, enjoying the magic Sam worked on him with his hands. Sam's hands slipped lower still, rubbing lightly over Clay's arse over the fabric of his underwear and Clay's cock fought against the mattress with every will power it possessed, making Clay's heart race.

“You okay?” Sam asked as he shifted backwards between Clay's legs, his hands moving continually.

“Mhm,” Clay's body went rigid with tension and arousal. He managed to shift slightly, his cock rubbing against the mattress. He couldn't hold back his moan this time as Sam hooked his fingers in the elastic of his pants and slid them down enough to expose his buttocks. The touch of Sam's fingers were electric and Clay shivered at the sensation — moaning louder. The tension pitched itself in his stomach as he grinded against the bed helplessly. He felt Sam's hot breath hovering over his sensitive arse as he trailed light kisses on it.

“Please, turn over,” Sam begged, his husky voice barely above a whisper. “I want to blow the fuck out of you.”

“Shit, fuck...yeah,” Clay rolled over hastily, well past embarrassment now. He wanted Sam's lips on him more than anything.

Sam smiled up at Clay's heated cheek from where he hovered over Clay's groin. His smile was mischievous. He dipped his head down and nuzzled Clay's bulge through the fabric material that covered it, mouthing at the shape of him. “How about we take these off then? They seem to be getting in my way.” He pulled Clay's underwear down and waited for the latter to shift his legs in order to take them off completely. Then Sam pushed Clay's legs apart and settled in between them.

At first Sam took a few minutes to stare at Clay's cock which elicited a sense of self-consciousness and dread in Clay as he struggled to stay calm under the scrutiny of Sam's blue eyes. He winced as Sam's fingers dug more into his thighs, and he suddenly felt vulnerable. Although Clay's dick was of a decent size, it was nothing compared to Sam's which he had seen through the dark briefs. What if Sam considered him a disappointment and called off the experimentation? He could never get another good enough, necessarily hot teacher to put him through the rigours of gay sex education. Panic rose to an alarming level, threatening to overpower his arousal but when Sam's fingers circled around his cock, he heaved a momentary sigh. Sam began pumping him slowly, rolling back the foreskin to reveal the dark-pink head with each stroke and spreading the cum around evenly.

“This is huge too. A lot bigger than those twinks I normally fuck,” Sam smiled as if to dissuade Clay from his insecure thoughts. He lowered his head and parted his lips around the head of Clay's cock and sucked, his tongue swiping out to tickle the base. Clay writhed under the pleasure of it, moaning louder. “Fuck, Shit, yeah, more, oh God, Sam more!”

He looked down, biting his lips harder as Sam worked his cock like a pro. Jesus! Never in his life had a blowjob been so divine. When Tina normally did hers, he was too unaffected to feel any pleasure and grew irritated at her, constantly slobbering his dick with saliva which made his shorts itch afterwards. But in Sam's mouth, Clay felt truly helpless as the blonde took him in more and more, his tongue exploring corners Clay never knew existed. Sam's mouth grew more intense as he pulled and sucked insistently, his grip tightening on Clay's thighs as he spread them wider. The sight of his messy, shiny locks and broad shoulders made Clay moan as he thrusted into Sam's mouth helplessly. Occasionally, Sam would move a hand down to stroke his own cock and that was the point Clay decided he'd had enough.

“Fucking hell!” He moaned, fingers twisted on the pillow above his head as his body arched and shuddered at his release, Sam swallowing every thick drop he squirted, sucking and licking till Clay's shoulders relaxed and he was spent.

Sam rolled off, meeting Clay's eyes. Sam's eyes were dark with desire, his hand still wrapped around his cock as he stroke it gently. Clay wanted to see all of it.

“Oh, fuck,” he panted. “Show me, please.”

Sam crawled up to straddle him seductively, his strong thighs braced on either side of Clay as he knelt fully, jerking himself off. Clay was right, his cock was thick and rigid, bigger than Clay's and the head was darker and more blunt. “Shit, I'm so close babe.” He groaned through gritted teeth.

Clay reached for him, desperately craving to feel the weight of Sam in his hand. He took over, working his hand up the base as he felt the pulse and heat under the skin, the power of Sam's dick overpowering. Sam cried out noiselessly when he came with his head thrown back and his shoulders shuddering. The muscles on his belly spasmed as he spilled his seed over Clay's fingers and chest.

When he was finished, Sam fell forward, supporting his weight on his arms as he kissed Clay thoroughly. Clay held his shoulders, enjoying the play of the muscles under his hand. They cuddled for hours before they finally parted to go wash off.

“Have you got any spare towels?” Sam grinned as he saunted nakedly into Clay's bathroom.

“No, but you could use mine.”

“That'll do.” Sam's lips curled up into a mischievous smirk. “I'm going to shower now and...you can come in if you want. I won't wait long babe,” He turned, treating Clay to another spectacular view of his arse as he closed the transparent door behind him. Clay smiled to himself for a very long time before choosing to join his teacher for a bath.
