Chapter Text
“Oh,” Rain moans, as another spurt of pre splatters onto his stomach. “Mountain, c’mon. Not fair.”
“Life is unfair,” Mountain agrees. Propped on one elbow, stretched out beside Rain’s quivering body, he’s got the best view in the world. He drags a finger up the underside of Rain’s cock, watching it twitch. So sensitive.
Rain sniffles. “How many more?”
“Haven’t decided.” He’s so messy. So wet. Absolutely covered in his own pre, covered in Mountain’s cum. It pools in the dip of his navel, in the creases of his hips. Mountain had made Rain jerk him off first, just to taunt him. Just to show him what he was missing.
Now he closes his fingers around the tip of Rain’s cock, teasing. Drags his loose fist up and down, nothing more than a brush of skin on skin. Barely any contact, but Mountain is sure Rain’s worked up enough that he could probably cum from that alone.
That’s a plan for another day.
Another glob of pre squeezes out of his slit. Mountain gathers it up onto his fingertips and smears it across Rain’s twitching stomach. He's been at it long enough that the smaller splatters have begun to dry, thick and tacky. It’ll be a pain to clean up later.
“Mount,” Rain whines, and Mountain takes his hand away as that blushing cock twitches valiantly. Rain’s hips twitch right there with it, a sad little motion that has Mountain laying a palm on his thigh to soothe him.
(He’d normally lay that palm on Rain’s stomach, but he doesn’t feel like getting sticky handprints all over everything.)
“That looked close.”
Rain whimpers, miserable, fingers digging creases into the sheets. “It was.”
“How close?” Mountain takes the tip of Rain’s cock between his thumb and index finger, rubbing up and down. He’s really hard. It’s got to hurt.
“Really close,” Rain gasps.
Mountain doesn’t know why Rain does this to himself, really. Kinky little masochist. He grabs Rain’s cock and squeezes the base nice and tight, and Rain throws his head back, hitting the pillow with a muffled thump.
“You're horrible,” Rain groans. “I wanna cum.”
“I know.”
“Let me cum.”
“Nope.” Mountain uses a finger to press Rain’s cock against his stomach, into the puddle of sticky white fluid. It springs back up when he lets go, and a string of pre follows, stretching upwards in a milky white line. “So wet,” he says lovingly.
“Could be wetter,” Rain grits out. “If you weren’t being an ass.”
“Mm-hm.” He does it again, admiring the way it glistens in the soft light of his bedroom, and he swears Rain arches his back a little this time, bony shoulders pressing dents into the mattress.
“What will you do?”
Rain blinks stupidly up at him. “Huh?”
“Can’t think now, can you?” Mountain slaps one of his nipples, gentle and playful. Again, no force, but Rain shudders all the same. “What will you do for me? If I let you cum?”
“Anything,” Rain says immediately.
Mountain smiles. It’s always a fun question to ask, because Rain tends to forget what he says when he’s horny. Anything includes doing this again.
“Promise?”
“I swear! Please, come on, let me—”
Mountain holds out his pinky, just for good measure, and he has to hold in a laugh at how desperately Rain links his pinky with Mountain’s, thumb-to-thumb.
“Okay,” he laughs, lacing his sticky fingers with Rain’s trembling ones. “Okay, you can cum. I’m sorry, tadpole. I’m sorry I made you wait.” He wraps his fingers around Rain’s dick, feels it drool even more slick. Gives it a little twist this time, just the way Rain likes it.
“Promise you won’t stop,” Rain gasps, and Mountain does feel a little bit guilty. Like he’s broken Rain’s trust, or something—which he has, he supposes, but still. Guilty.
He leans in to press their lips together, more to shut himself up than Rain. Rain whines into it, lips parting automatically, and Mountain gives him one cursory lick before pulling away.
“Do you really need my hand?” he asks, and the way Rain’s face twists in despair has him regretting it immediately.
Not sounding very threatening, Rain hisses, “I will drown your plants.”
That’s yes, then.
“Please don’t do that,” Mountain says gently.
“Gonna cum,” Rain chokes out, and Mountain doesn’t stop this time, just keeps jacking him until he’s squirting thick, hot ropes all over himself, all over Mountain’s hand, hips jerking into his fist. His stomach gets drenched with it, the sheets thoroughly soaked with the excess dripping over the sides of his waist. There’s so much, an honest-to-Satan impossible amount. A fucking sea of cum, Mountain swears.
Rain’s got a hand thrown over his face, hiding himself, but Mountain can see the way he’s biting on his lower lip, and decides he wants to see the rest, too. He knocks that hand away, so Rain has no choice but to look at him with those wide, wet eyes, tears of overwhelm threatening to spill over.
“Good?” he asks, and Rain manages a tiny nod. “Play with it,” and Rain brings a quivering hand to his stomach, dips his fingers into the mess. Something like wonder in his eyes as he holds his hand to the light, watches it glisten.
Mountain can’t resist. He leans in and takes Rain’s fingers into his mouth, tasting him, tasting them. He groans, stroking Rain even faster, like he’s trying to milk even more out of him. Rain pushes him away.
“No more, please,” he whispers, so Mountain wipes his hand on the sheets, brushes Rain’s hair out of his eyes. That’s all he manages before Rain’s eyes are slipping shut. Straight to the post-orgasm snooze.
“You made a mess,” Mountain says softly. He dips a finger into the splatters of cum on Rain’s chest, tracing it around his nipples, along the lines of his ribs. Playing with it. Making it worse. “Better clean it up.”
Rain just nods, beyond words. His head lolls to the side, and all Mountain can see of his eyes are two dark slivers of blue, shining with unshed tears.
“M’tired,” he says absently, still not quite there. “Feed it to me.”
