Step-Son's Rare Condition: Rimmed by Step-Dad

The examination room still smelled of antiseptic, and the paper on the table crackled under Declan's palms. At twenty-two, only three weeks past his college graduation, he sat in a thin gown and tried not to look at the man beside him. Marco, forty-eight, his step-father of four years, filled the visitor chair with the same quiet bulk Declan had always trusted. Neither of them had expected the afternoon to turn like this.

Doctor Monica folded her hands over the chart. "The labs confirm a rare hormonal condition. Your prostate isn't releasing the enzyme your system needs. Pills won't reach it. Neither will a shot." She looked from Declan to Marco without softening it. "The only treatment that works is direct oral stimulation. Mr. Moretti, your saliva carries a matching enzyme we almost never see. When you rim him, the enzyme in your saliva and on your tongue stimulates the medicine his body needs. You'll have to rim him. Thoroughly. Often."

Heat climbed Declan's throat. Marco's jaw set, but he didn't look away. They had always been close in a steady, ordinary way, the kind of bond built from shared dinners and long talks and nothing like this. Now the space between their chairs felt suddenly charged, thick with something neither man had dared name.

"How soon?" Marco asked. His voice had dropped.

"Today, if you can," Monica said. "Waiting makes the cramping worse. This is your choice, both of you. I can send you to a clinic if you'd rather a stranger."

"No," Declan said, too fast. He swallowed. "If it has to be you, I want it to be you."

Marco's hand settled on his knee, brief and steady beneath the gown. "We'll do it at home."

In the car, silence held. Declan watched the gray street slide past and felt his cock stir every time he pictured Marco's mouth where the diagram had pointed. By the time the apartment door shut behind them, the tension sat low in his gut, hot and impossible to dismiss. Marco locked the deadbolt and turned, and the look on his face was no longer only worry.

"Say it out loud," Marco said. He set his keys down and didn't pretend this was still only medical. "Before we do anything, I need to hear that you want it. Not because a chart told you to. Because you want my mouth on you."

Declan's pulse kicked. He had spent the drive hard and ashamed of how hard, and the shame was already losing. "I want it. I've been thinking about your tongue since she said the word rim. I didn't know I would. I do."

"Say what you'll do to my ass," Declan added, voice cracking. "I need to hear it while I'm still standing."

Marco stepped closer, and his mouth curved, dark and sure. At forty-eight he still moved like a man who worked with his hands, broad through the shoulders, salt at his temples, the same steady eyes Declan had trusted for years. Now those eyes dropped to the front of Declan's pants. "You're already thick for me. Gladly. I'll tell you all of it."

"Yeah." Declan didn't cover himself. "Talking about it is making it worse. Or better. I don't know."

"Better," Marco said. He reached out and palmed Declan through the denim, slow, giving him every second to pull away. Declan pushed into the touch instead, a rough sound catching in his throat. Marco's thumb stroked once along the ridge, and Declan's hips jerked. "Good. Then listen. I'm going to get you bare. I'm going to spread you over the arm of that couch and hold you open. I'll lick you first, long and wet, until your hole softens. Then I'll push my tongue in and fuck you with it. When you're shaking, I'll add my fingers and work that spot while I suck your rim. You come when you need to. I'll keep going until your body gives us what the doctor wants. And I'll like every second of it."

Declan's knees nearly went. His cock strained so hard the zipper hurt. "Jesus, Marco."

"Step-dad," Marco said, quiet, testing. "If you want to say it."

"Step-dad." The word landed hot. Declan fumbled his belt open. "Please. I need you to start. I'm consenting. I'm begging. Do it."

He shoved his pants and briefs down and bent over the couch without being asked again, chest to the cushions, ass tipped up, legs spread as far as the denim at his ankles allowed. The apartment was warm. His hole clenched in the open air, already slick with nerves and want. He looked back over his shoulder, flushed, hard, unmistakable.

"Please," he said. "Rim me. Treat me. I want your tongue in my ass."

Marco's breath left him in a rough exhale. He dropped to his knees.

Marco knelt behind his step-son and set both hands on Declan's ass. The cheeks were firm from years of running, pale where the sun never reached, and they parted under Marco's grip with a soft give that made Declan's breath hitch. Cool air hit his hole. Then heat.

The first lick was a long, wet stripe from the back of his balls up over the tight ring, slow enough that Declan felt every inch of tongue. Marco did it again, flatter, broader, painting him until the skin shone. Saliva cooled and warmed in turns. Declan moaned and pushed back, shameless, chasing the next stroke.

"Stay open for me," Marco said against him, and spread him wider.

He licked in steady lines, up and down, then circled the rim with the point of his tongue until the muscle fluttered. Declan gripped the couch cushions and swore. Each pass made him softer. Each pass made him harder. His cock hung heavy between his thighs, dripping onto the rug, untouched and aching.

Marco sealed his mouth over the hole and sucked. The pull was obscene, wet, loud in the quiet apartment. Declan cried out and rocked back onto his step-dad's face, riding the suction, feeling his rim stretch and cling. Marco groaned into him like he had been starving for it. His tongue pushed, patient and relentless, working the ring until it yielded.

Then he was inside.

Declan went tight all over and then loose, a broken sound tearing out of him as Marco's tongue thrust deep. It was hot, slick, alive, curling and stroking the sensitive inner walls. Marco fucked him with it in short, hungry strokes, pulling out to lap the rim, then driving back in, over and over, until Declan's thighs shook and his hole gripped greedily at every withdrawal.

"More," Declan gasped. "God, step-dad, more. Don't stop. Eat me."

Marco answered by sucking the rim again while his tongue worked inside, filthy and thorough, spit running down Declan's taint. One thick finger joined the tongue, sliding in alongside it, coated and easy. Declan pushed back onto it with a desperate roll of his hips. A second finger followed, stretching him, scissoring gently, then curling until they found the swollen gland the doctor had named.

Pleasure snapped white behind Declan's eyes. "There. Right there. Fuck."

Marco kept his tongue busy on the rim, lapping and sucking, while those two fingers stroked the prostate in a steady rhythm. His free hand reached under and wrapped Declan's cock, fist tight, thumb smearing precome over the head. Declan rode both at once, ass working on fingers and mouth, cock fucking into Marco's grip. The wet sounds filled the room. Marco's stubble scraped the tender skin of his cheeks and only made him wilder.

"You're clenching," Marco said, voice muffled and rough. "Give it to me. Let that medicine come. I've got you."

Declan couldn't have held it if he tried. The orgasm hit hard, ripping up from his prostate and out through his cock in thick, pulsing spurts that striped the couch and Marco's fingers. He shouted, hole spasming around tongue and fingers, body jolting with every wave. Marco didn't pull away. He stroked him through it, slower, milking each pulse, and kept licking, lapping at the fluttering rim as if he could drink the reaction straight from the source. Declan felt something deep loosen and flood, a hot internal rush that made his knees buckle and his moans turn wrecked. Marco groaned in approval and pushed his tongue deeper, chasing it, swallowing spit and the slick his step-son's body kept giving him.

"Again," Marco murmured when the first peak ebbed. "Doctor said thoroughly. You're still twitching. Stay bent for me."

Declan nodded, boneless and eager, and Marco started over. Long licks. Deep thrusts of tongue. Two fingers pumping that spot while his mouth sealed and sucked. The second orgasm built faster, meaner, dragged out of an already sensitive body. Declan begged for it, voice cracked, calling Marco step-dad in every other breath, telling him how good his tongue felt, how he wanted to be eaten until he couldn't stand. Marco gave it to him. He alternated exactly as he had promised, thrusting his tongue, then sucking the rim raw and sweet, fingers never leaving the gland. When Declan came the second time it was almost dry at the tip and devastating everywhere else, his hole gushing slick around Marco's mouth, the older man lapping it up with hungry, grateful sounds, stroking the spent cock until Declan sobbed and pushed back for more anyway.

A third crest took him while Marco's fingers crooked hard and his tongue fucked in deep. Declan shook apart, crying out into the cushion, ass grinding on his step-dad's face, every nerve lit. Marco held him open and didn't stop until the spasms faded and Declan's hole softened, wet and used and calm. Only then did he ease his fingers free and press one last, slow lick over the swollen rim, gathering what remained, thorough to the end.

Marco rose on unsteady legs and turned Declan in his arms. The younger man's face was wrecked, eyes wet, mouth open. Marco kissed him deep, tongue sliding in so Declan could taste himself, salt and spit and the faint sweetness of what his body had given up. Declan kissed back hard, gripping his step-dad's shirt, whimpering into the taste. He wanted Marco to feel how completely he consented to every next time.

"That should hold you for the day," Marco said, thumb on Declan's lip. "She still wants it regular."

Declan smiled, shaky and satisfied. "Then we repeat it. I want that."

"Shower. I'll wash you."

They headed down the hall together, hands linked, both of them grinning.

At the bathroom door Declan stopped, voice low and sure.

"Same time tomorrow, step-dad — will you put me on my knees in the shower and eat me until I come on the tile?"
