Dave spit out the blood that was on his lip. He wiped his mouth, and glared at the troll across from him. Then he lunged at him again, kissing him more fiercely, rubbing the other's nubby horns.
Karkat growled, and ran his fingers down Dave's bare back, creating red claw marks.
It hurt like a motherfucker, but Dave could care less at that movement. All that mattered was making the motherfucking troll bleed. He bit down on Karkat's lip, hard. He tasted blood that was not his. He smirked within their kisses, and pushed Karkat against the wall of his room, and continued making the other moan.
"Fuck," Karkat moaned, as Dave bit on his neck. Karkat dug his nails into Dave's back, and felt something sticky on his fingers. Blood.
"Ow! God dammit!" The cool kid groaned.
Karkat took this chance to shove Dave away, and take control. He jumped on Dave, and shoved him toward the bed. They both landed on the mattress, and immediately began biting, thrashing, and growling.
The troll straddled the other, and licked Dave's neck, making the other shudder. He licked Dave's jaw, and up to the corner of his mouth.
"Gog I hate you," the human gasped, as Karkat sucked on the corner of his mouth.
"The feeling is mutual," the troll growled, biting down on Dave's shoulder, drawing more blood and creating another bruise.
Karkat licked down Dave's neck again, and went down to his chest, making patterns with his tongue.
"Oh sweet jegus," Dave panted. "Fuck me."
Karkat smirked. "With pleasure." He unzipped Dave's jeans with his teeth, and pulled them off with ease. Not even glancing at Dave's spades boxers, he pulled them down, looking at Dave's bone bulge, and smirked. He leaned down and licked Dave's ear, and whispered. "I am going to make you bleed, motherfucker."
Dave moaned. "Whatever you say, Vantas. Just get inside me."
And they preceded to have the most gruesome round of kismesis sex ever in existence.
