John lightly kicked the door, his hands barely keeping a hold on the large grocery bags that balanced on his arms. The door swung open, revealing a grinning Nepeta. "John, you're back! Let me help you with a few of those." The weight on John's arms lessened, allowing him to adjust the bags with ease.
"Thanks, Nep," he said as the two set the plastic bags on the kitchen counter. Nepeta pounced on the slightly taller boy, squeezing him tight. "Woah, there. I've only been gone forty minutes. Did you really miss me that much?"
"It's no fun without you here," Nepeta whined, "Equius isn't here, and everyone just sat in each other's rooms and talked or whatever they do." John chuckled, gently patting her on the back. She clambered off his torso, a relieved yet slightly annoyed expression spread across her features.
"I am honored that you think everyone is boring when I'm not around," John bowed, causing Nepeta to giggle into her paws. "Though, if you don't mind, I would like to talk to Karkat for a bit. Do you think you can tough it out until then?" She rolled her eyes, punching him playfully on the shoulder. He grabbed his shoulder, feigning hurt. Nepeta giggled again.
"You're so funny, John. Promise me you'll never stop making corny jokes and such, even after you die," she crossed her arms, eyebrows drawn and a hard stare to emphasize how serious she was about it.
"I'll stop making jokes when you stop liking cats," John grinned, and hugged Nepeta one last time. "Now, if you'll excuse me..."
John climbed up the three short flights of stairs up to the floor where he and his- as Karkat liked to put it- matesprit shared a room. A strange noise reached John's ears, followed by another. As he tiptoed down the hall, he realized the noises were moans. Is that Terezi? thought John. Could she at least try to keep it down. A muffled cry resounded through the walls and down the corridor. He immediately recognized whose it belonged to. John's pace sped up until he was running down the hall. Now he could hear whimpers and the creaking of a bed coming from within the door next to the distraught teenager.
John was standing in front of his room. With shaky hands, he slowly opened the door and stepped inside. The scene occuring before his eyes made his stomach churn.
Terezi was naked, straddling a flustered Karkat. The sheets were soaked in teal and crimson. "Terezi, oh god pl-" Karkat's plea was cut off by a guttural moan. Tears tumbled down John's face, blurring his vision. He watched, horrified as his matesprit threw himself against her, eyes shut tight. Whimpers escaped the troll's lips, breathing hard and shallow.
"I love it when you get all flustered," John heard Terezi breathed into Karkat's ear, her hand reaching up to rub his nubby horns. Karkat moaned in response, his face turning into a deeper shade of red. "Say my name," Terezi ordered. John felt as if he were to vomit.
"T-Tere- holy fucking shit," Karkat practically screamed. His claws raked down her back, blood appearing in its wake.
"Say it."
"Terezi!" Karkat screeched, his eyes snapping open. Genetic material pooled beneath them. John choked, hitting the wall behind him. Karkat's eyes suddenly met his, wide with shock and fear. "John," he whispered. John shook his head slowly, angrily wiping the tears off his cheeks. He bolted out of the room and up the corridor, sprinting up the flights of stairs until he finally reached his destination and collapsed onto the floor.
