I'm breaking my rules again
YooSu
R to NC-17
also known as 'that one time when amy and kacy spent a good hour or so looking at pictures of junsu being a good christian then talking about him sucking cock'
"Sir?" Junsu asks, expression apprehensive. He doesn't want to look over his shoulder; there's nothing to stare back at him but the pinewood wall. "Sir, is something wrong?"
"Nothing. I." Yoochun breathes, mere inches between their lips. He sucks in a small breath when Junsu shifts against him, obviously feeling uncomfortable with this position. "I just." Yoochun looks at that face--so untouched. "I need to confess something to you."
"Shouldn't you go to the confessional?"
"This is just for you."
"I." Pause. "Okay," Junsu licks his lips nervously. "Okay."
Yoochun kisses him.
It's sudden, a rush, forbidden feelings and tasting so sweet that Yoochun dives deeper into it, wanting more. A small gasp is all it takes for Yoochun to worm his tongue past virgin lips, exploring and savoring the flavor that is purely Junsu--innocent, pure, delicious.
Junsu tastes like fruit and, somewhere in the back of his mind, Yoochun thinks the irony is all too amusing.

"Yoochun. Yoochun, wait," Junsu pants, body arching into the touch even as he protests. "Not- not here, wait."
"Junsu," Yoochun growls, voice so deliciously low that it makes Junsu shudder. There's a soft bite to his neck and Junsu jerks, hands stuck in Yoochun's always tangled hair. A kiss, fingers tickling his inner thigh, and Junsu locks his legs around Yoochun's waist. "A bit late for waiting now."
Junsu whimpers in reply, trying to push away the part of his mind saying this is wrong and instead trying to focus on the feel of Yoochun's cock inside him; thick, hard, pressing into him with care. Yoochun has little patience for some things (most things sexual, Junsu realizes) but he's going slow and lacing gentle kisses along the line of Junsu's jaw.
A large hand wraps around his length and all it takes is two firm strokes before Junsu groans, mind going blissfully white.

Junsu hasn't ever really had the experience of tasting cock before (he's a good boy: goes to church, listens to his mom, prays every night, thanks the lord for his daily bread, etc etc) so he's a bit surprised at the bitter taste of semen. He's also surprised that he actually doesn't mind the taste. The third surprise comes when he tries to get his lips around Yoochun's cock and actually fits it in his mouth because Junsu didn't know his mouth was that big.
He's new to this, but he trusts Yoochun and he trusts his ears. Whatever it is he's doing (namely bobbing his head, tongue and teeth scraping the sensitive skin) he's obviously doing it right. Yoochun is babbling; his head is thrown back, hair slicked down to his face with sweat.
"Lord, Jesus Christ, God, damn it, I have sinned," he pants, knuckles white from the grip he has on his seat. "God, I have sinned, I tainted the innocent."
Junsu deep throats him instinctively and Yoochun jerks, voice hoarse and echoing in the empty room.
"Shit, God, I do not ask forgiveness for this."
Junsu swallows with a smile.
