The air left Finn’s lungs as the greater girth stretched him. How wonderful to be prepared for a long, hard cock by a skilled hand. He was meant to be open and ready for them, and all he wanted was to pay back his men the pleasure they allowed him to feel.
Conall lay by his side, petting his hair and kissing his face. “Would you like Darin to touch your prostate?” he asked, running one of Finn’s coiled locks between his fingers.
“Yes. Please.”
Conall gave Darin a nod, and Finn sucked in a breath, steeling himself for the impending brush across his core. Nothing could’ve prepared him for the zinging lust that bolted through him when Darin crooked his fingers and rubbed Finn’s gland. A hungry groan left him. His mind was incapable of remembering how good direct stimulation of his center felt, and the mind-numbing elation surprised him every time.
Darin spread his fingers, parting Finn’s soaking wet, clenching hole. The stretch was delectable, providing a gentle burn that had Finn desperate for more. He gave a chain of sounds so debauched, they would’ve made a whore blush.
“Our insatiable merman,” Conall said, drenched with satisfaction. He took one of Finn’s rosy nipples between his fingers, twirling the center until a hard nub arose. Finn felt the twists all the way to his cock, which jerked helplessly in the air, begging for attention and getting none.
Darin drove in and out, widening him for what was to come. The sloshing noises heightened Finn’s arousal, and his insides strained with renewed urgency.
“P-Please,” Finn whimpered, making wide eyes at Conall. Even if it was Darin who touched him, Conall was the one in control.
“Please what?” Conall asked with an amused smirk and gave Finn’s erect nipple a merciless flick.
Finn shouted, pain and lust mixing into an intoxicating concoction. His mind was swimming, his body begging for release. “Need to come.”
“Darin, circle the base of Finn’s cock with your fingers. Use a good amount of pressure.” Darin did, and Finn hissed as his chances for a quick climax plummeted to zero. Fuck. “Plunge into Finn’s prostate.”
The firm prod at his sweet spot had him coming off the mat as blinding pleasure rushed through him. Finn cried out. His walls needily clenched around Darin’s digits, and his insides pulled taut like a bow. He groaned and cursed as his urges reached new heights. His cock jerked angrily. Darin’s cruel hold on him frustrated and aroused him simultaneously.
“Hmm,” Conall said in his ear, hot, damp words brushing the skin as his fingers played with Finn’s nipple, “what should we do with you? Deny you until you can’t help but detonate?” A gush of precum streamed out of Finn’s cock and onto his stomach. “You like the idea, don’t you?” Conall dragged a finger through the evidence of Finn’s excitement, smearing it across his abdomen. He scooped up a drop and brought it to his lips, closing his eyes and humming at the taste. He leaned in and kissed Finn, sharing the salty-sweet flavor with him. Finn sighed into his mouth, drowning in bliss as Conall’s tongue and Darin’s fingers fucked his holes.
“Darin,” Conall said as he pulled away, the word a purr, “make him scream.”
Oh damn. Finn’s gaze flew to Darin’s the very second his fingers nudged his prostate. A wordless shout bolted out of him, followed by a series of trembling moans as Darin rubbed him, relentless in his stimulation of his sweet spot. Their eyes locked, and Darin massaged his fingertips into Finn’s sensitive little bundle of nerves. Finn shuddered in pleasure, provoking Darin to trace and stroke his core until he broke into uncontrolled, full-body shivers. Conall held him close, arms wrapped around his head, his chest, whispering sweet nothings as Finn dissolved in need.
A broken sob spilled from his lips. “W-Want… want to come…”
“I know,” Conall said, voice low and soothing and at odds with Darin’s merciless hold on the root and the skilled fingers hammering his love spot. “And when you do, you won’t stop orgasming for a long time. We have a plan for you. One that will have you coming without pause while we fill your little hole to breaking point. We’re going to destroy you, and you’ll love every minute of it.”
Finn keened, looking straight into Darin’s eyes as his body answered Conall’s words with a lustful spasm. Mouth open, he panted, slutty sounds cascading out of him that affirmed Darin’s every nudge and prod.
“Fuck!” Finn cursed. “Fuck! Right… there. D-Don’t stop.”
He said more, but it was an incoherent jumble of half-finished sentences. His mind was no longer functioning. Darin and Conall turned him into a headless vessel for the lust they poured into him until he was on the brink of overflowing. Pressure mounted. His inner muscles strained, his hole tightened around Darin’s invading fingers, his cock twitched violently.
Had it not been for Darin’s unforgiving hold on his base, he would’ve long come, but Darin was keeping his climax at bay, tormenting his defenseless gland with generous swipes and thrusts while denying him completion. Darin’s practiced fingertips knew how to touch him to drive him mad. With varying pressure, they rubbed and kneaded him until he didn’t know up from down. Finn’s hands, holding back his legs, curled against the firm flesh of his thighs. Pathetic little noises rolled off his lips, telling Darin and Conall how much he enjoyed what they did to him.
His balls climbed toward his body. Despite his earlier orgasm, they were full and heavy, his merman body producing cum at a preternatural rate. The muscles at the base of his cock shook with tension, Darin’s vice grip working against Finn’s pelvic floor that strained with the need to break into wild contractions.
“You’re close,” Conall said in his ear, continuously thumbing Finn’s pebbled nibble. “I can feel it. Your body is so tense, it’ll snap if we give it the slightest leeway.”
“Y-Yes,” Finn pressed out between sharp intakes of air.
“You’ll get no leeway. Darin will make sure of it. His fingers are going to fuck you until either you pass out or your body takes what it needs. Which one is it going to be?”
Darin’s fingertips knocked against his prostate with the insistence of a messenger pounding on a door determined not to leave until it was answered. Would Finn’s body answer his call? Finn’s inner muscles tightened further until they could firm up no more. Darin let out a moan. He looked like he was about to come untouched, just from taking Finn apart. Then he lovingly stroked Finn’s prostate, the touch conveying so much care and affection that Finn couldn’t hold on anymore.
His balls slapped up to his body. A violent convulsion bloomed in him, every muscle expanding, contracting and expanding again in rapid succession. His insides pumped cum with ferocious power, and hot-white ropes volleyed out of him, splashing his torso, hitting him as far up as the tip of his nose. Conall licked off the drop there while Finn’s hole compressed and swelled around Darin’s delightful fingers. They never stopped massaging his gland, their finesse making him vellicate and come and contract over and over until his entire body was a twitching, orgasming heap.
“Darin, three fingers,” Conall said, sounding far away.
Darin pulled out, leaving Finn empty, seizing around nothing but air, and yet he wasn’t ready for the trio of fingertips tapping his little ring of muscle. Three had considerably more girth than two, and Finn tried to bear down, but his coming hole was uncontrollable, squeezing and releasing wildly.
“Push in,” Conall growled. “Make Finn yours.”
