"Just this. Just you," Sten sobbed, making Rask's heart clench as he redoubled his efforts.
Sten was dribbling again, his cock leaking steadily now as his orgasms rolled through him, spilling over Rask's hand. Lifting it to his mouth quickly, salt burst over the bergsrå's tongue. He licked it clean before returning to grip the warm velvet of Sten's cock, thrilling as the human bucked in Rask's hold from all the sensations.
Rask was so close now. He leaned forward, covering Sten's body as it clutched so greedy and hot and perfect around the bergsrå's cock.
Thrusts coming harder and faster, Rask grunted as he chased his peak in Sten's sweet clench and slide. His stone ached, his balls pulling tight. He wasn't going to last much longer.
"Oh!" Sten cried out as Rask buried his face in Sten's shoulder, driving harder and harder, until — with an urgent, sharp thrust — Rask slammed his hips forward. Burying his cock deep within Sten's hole, Rask's seed pulsed, and pulsed, and pulsed; marking the little human's deepest, most secret parts.
Rask plunged into him again, grunting, spilling his second load deeper still as Sten moaned; clutching Rask's wrists tightly where the bergsrå's hands were planted on either side of Sten's shoulders, bracketing him in.
For the third and last time, Rask drove his cock into Sten's welcoming body. Already so pliant and slick with the bergsrå's two previous waves, now Rask's final filled the little human to the brim.
With a shout, Sten buried his face into the pillows as Rask's stone surged within him; claiming him, stoppering the bergsrå's seed inside. The human's low keening was glorious to Rask's ears, deep and reassuringly enthusiastic. Enough to quell even Rask's anxieties that Sten should find this enjoyable too.
Then Rask began to gently rock.
"Ah, that's incredible. Oh—!" Sten wailed as Rask's stone stroked his sweet spot, voice shining with pleasure. The little human squirmed and writhed, cock dribbling all over Rask's hand as the bergsrå massaged him from the inside, Sten's hole fluttering as it adjusted around the bergsrå's wholly filled stone.
"So much," Sten whispered, his hands kneading at Rask's bed furs like a satisfied house cat.
"Sten alright," Rask murmured, pressing kisses into Sten's shoulder to calm his pounding heart. "Sten will take Rask's stone. Rask will take care of Sten."
Sten laughed, and the sound made something ease inside Rask's chest.
"Sweet Sága; you feel amazing. Please don't fret so much, Rask."
"Want make good for Sten," Rask admitted. "Want Sten come back."
"After this? Oh, just you try and keep me away," Sten chuckled, clenching down on Rask's cock, and Rask shuddered at the sensations it sent surging through his stone.
Rask's fingers slid along the curve of Sten's hip, unable to properly convey the words with all the blood rushing into his stone. Instead, he wrapped his limbs around Sten's body and rolled them onto their sides, able to relax now that he was no longer in danger of crushing the little human with his weight.
He nosed at Sten's shoulder as he trembled around the bergsrå's stone, so very pleased at how well Sten was taking him.
Rask hadn't felt such contentment… Well, it’d been a long time. Too long, that was clear. And here he was, already anticipating Sten's next visit, even while the man remained impaled on the bergsrå's cock.
"So uh…how long does your stone usually last?" Sten asked after a while.
"Not so long, if Sten very still,” Rs answered him. “Soon Rask's stone soften, then Sten more comfortable. But try not to move until fully gone, or stone returns."
Sten twisted, looking over his shoulder.
"Really?! Like, no moving at all?"
"Sten moving."
"Fuck," Sten said, turning his face back toward the furs, his hand reaching down to curl around Rask's own. "Okay. Okay, I can be still. Next time I'll have to remember to stash some snacks nearby. Oh, and water."
Rask growled, his stone throbbing at the thought of 'next time'.
"Sten wish this again?" he whispered.
"Of course," Sten mumbled sleepily. "I made a bargain to come back here, didn't I?"
Rask frowned. "This not part of Bargain," he reminded Sten.
"I know," Sten yawned. "Lucky me, huh?"
