John hugged Karkat and smiled.
"Please?" John whispered. Karkat let out an obviously forced sigh of annoyance. "Fine…" The troll sighed. They were laying in a light blue bed, which is John's favorite color. Karkat slowly slipped of John's pants as he snickered in pleasure. The gray skinned human-like alien tore off John's pants and saw his bulge. Karkat stuck out his tounge and opened his mouth, wrapping his lips around the human's cock. John groaned in pure pleasure. Cum streamed out of his cock like lava out of a volcano, glazing Karkat's lips and trickling down his throught. Karkat stopped sucking John's bulge and quickly flipped him around. John gasped, confused. The troll then shoved his penis up the human's ass, and John groaned in pain. Karkat dug deeper and harder. Karkat's hands were on the pink flesh-monkey's back and scratching him. He knew that John was in pain, but soon he will feel the strong wave of pleasure. Karkat stopped shoving and pulled it out. He collapsed, gasping from exhaustion. John took his chance and bit Karkat's neck hard. Karkat let out a huge orgasm as John bit harder. He slid his penis in Karkat's open mouth, letting more hot creamy cum slide down his mouth. To John's confusion, Karkat spit out the cum and grabbed John's head, pulled it towards his, and started making out with him. With Karkat's tounge In his mouth John rubbed his cock against Karkat's stomach. John was exhausted, and so was Karkat. They stopped a few minutes later and gasped for air, sweating. "Well… that is what human sex is like?" Karkat asked between breaths. He smirked and didn't wait for an answer. "Ready for round 2?"
