"Don't cum yet."
Zach moaned through the underwear stuffed in his mouth as Dion's voice breathed in his ear. They were both naked in Dion's bed, Zach laying on top of Dion and wrapped in his arms. While Dion's lips sucked on Zach's neck one of his hands explored Zach's chest, occasionally pinching and twisting his nipples, while his other hand relentlessly stroked Zach's dick, wet and loud from the constant stream of pre Zach was leaking.
Zach stretched against Dion's body, his ass rubbing against Dion's dick as his hand reached behind his head to grasp Dion's hair, his dick bucking into the handjob. They'd been going for 20 minutes and Zach's whole body was covered in sweat as his dick felt beyond ready to burst. But he wasn't allowed to cum yet, no matter how desperately he wanted to. And he'd been desperate for awhile.

Zach had come over late 2 nights earlier to spend the night with Dion. When he got to Dion's room they both stripped in seconds before they started making out on Dion's loveseat. They'd been dating for a little over a month, and far from slowing down, their sex drives had only gotten more intense the longer they'd been together.
"How fast do you think I could make you cum?" Dion asked, grinning at Zach as he straddled Zach's waist and teased Zach's dick along his smooth ass crack.
"How fast do you want me to cum?" Zach asked back, gripping Dion's ass and giving it a sharp smack.
Dion wrapped his hand around Zach's neck and pushed Zach's chin up with his thumb to kiss him deeply, Dion's tongue searching out the back of Zach's throat. When he pulled it out he kept his face inches from Zach's and breathed, "As fast as you can."
Zach couldn't help but giggle, "No you don't."
Dion was a little surprised at the reaction and smiled curiously at his boyfriend, "And why's that?"
"I mean, as fast as I can would be like, right now. Immediately. I assume you'd like a little more action than some light rubbing," Zach said, his dick searching out Dion's hole and poking at it.
Dion couldn't help but relax and push back against Zach's massive dick, letting the very tip just barely enter his hole, rubbing his own dick against Zach's abs as he did so. Then he sat back up.
"If you're bout to shoot from a little rubbing how much action am I gonna get out of you anyway?" Dion teased.
"As much as you want. All night even," Zach said, eager to get back inside Dion as the sexy junior kept straddling him.
Dion pushed Zach back into the loveseat and sat down on Zach's waist, Dion's taint resting against Zach's dick.
"So let me get this straight," Dion grinned, "You could shoot right now, but you could also fuck me all night long, am I hearing this right?"
"Yup," Zach grinned back.
"And how does that work?" Dion asked, poking Zach's sides.
"Just how it is. I can cum whenever I want to, I think it's something to do with the hyperspermia." Of course Zach knew his control over his orgasms had everything to do with his massive loads, even if the cause was magical not medical.
"Are you serious?" Dion asked, shocked.
Zach nodded with a sly grin. Dion couldn't help but grin back and held Zach's arms behind Zach's head. "Prove it," Dion said, "cum right now."
"If you say so," Zach smiled, and Dion's dick twitched as he watched Zach's eyebrows turn up and his teeth bite the tip of his tongue the way they often did when Zach was about to shoot. Then suddenly Dion felt Zach's dick jump against his taint as cum shot against it and the back of his balls.
"Holy fucking shit," Dion laughed looking in amazement down at Zach, flush after cumming, "You actually did it. How the fuck can you do that?"
"I don't know," Zach smiled, sliding his dick along Dion's cum covered taint, "Just a muscle I got. Like asking how do you decide to piss."
Dion stared at Zach barely able to believe it, "You are ridiculous, you know that?"
Zach blushed, worried he might've shared too much. But as soon as Dion realized Zach was embarrassed he flashed him that killer smile that lit up his whole face, "I love it. Cum on demand." And he brought his lips back to Zach's as they made out.
"Now," Dion said, pulling away from the kiss, "You made a mess."
Zach grinned as Dion stood up and motioned for Zach to lay down flat on the couch. Then Dion's knees straddled Zach's head and he sat his taint against Zach's face. Zach's mouth immediately got to work licking and sucking off his salty sweet cum as Dion did the same to Zach's still hard dick.
Admiring Zach's penis Dion had an idea. As Zach started sucking on his balls Dion gripped the base of Zach's dick, "Do it again." And feeling Zach moan into his nuts Dion watched amazed as Zach's dick twitched and started shooting again. Dion laughed and then locked his lips around Zach's dick, swallowing a load that was as big as any Dion had ever shot but comparatively mild for Zach. Dion loved the way Zach writhed beneath him as his tongue flicked around his dick with its post-cum sensitivity.
He only pulled off long enough to say, "Again." Dion readjusted so his hole was at Zach's mouth, and he felt Zach's tongue quiver against it as Zach's dick started to pulse in his mouth, shooting a third load straight onto Dion's eager tongue.
"Don't stop. Keep going, as many times as you can," Dion said putting Zach's dick back in his mouth, not sucking at all just holding the head between his lips as his tongue flicked across Zach's dickhead making him squirm.
Zach's dick jumped again, and again, and again. With each pulse Zach's loads got smaller and smaller, even as his dick got more and more sensitive. By the 6th time Dion felt Zach's dick twitch in his mouth he was shooting dry, and Dion had to hold Zach's legs down with his arms and Dion's ass was less there to be rimmed than to hold Zach's face against the couch as he writhed beneath Dion's flicking tongue.
