BECKS, THIS IS FOR YOU SINCE I GOT THE IDEA FROM YOUR POST! I HOPE YOU LIKE IT:D
Blaine stood at the doorway, watching as Kurt backed out of the driveway. He waved before shutting the door and turning around, coming face to face with Shane.
"Shane! Wh-what are you doing here?" Shane stood there, leaning against a post for the stairway and smirked.
"Sounds like you and Kurt finally lost your V-cards. Took ya long enough!" He punched Blaine lightly in the shoulder and the shorter Anderson’s mouth fell open before snapping shut. Blaine figured if he kept calm he could play it off.
"I don’t know what you are talking about." He smiled softly to himself before continuing. "How long have you been here?" Blaine walked past his brother and headed up the stairs, hoping to get to his room fast enough that he could just lock Shane out and ignore him.
"Since last night." Shane danced up the stairs and caught up to Blaine in no time. "Reed was really tired after the play, so I told him we could crash here." Blaine’s eyes grew huge, but he stared straight ahead. "Reed was asleep almost as soon as he laid down and I was about to be asleep, but I heard something.” He moved in front of Blaine, stopping him in his tracks and staring him straight in the eye. “I heard moaning. So I tried to play it off as another one of yours and Kurt’s heated make out sessions,” Shane raised an eyebrow. “But just as I was about to fall asleep, again, I heard Kurt practically screaming your name.” Blaine blanched.
"I-I…." He looked around frantically. "You shouldn’t have been here in the first place!" Shane smirked before pelvic thrusting.
"Yes! Blane got some!" He stuck his tongue out and started doing obscene things with it as he slapped the air over and over as if he were spanking someone. "Took you long enough!" Shane wrapped his arms around Blaine’s neck and started messing up his hair before Blaine could shove him away.
"What is wrong with you? How are we even related?" Blaine moved past Shane and continued up the stairs.
"Little brother finally got laid!" Shane laughed and followed after his brother, who huffed.
"You’re the little brother, Shane." Shane shook his head.
"Not in height." Blaine had finally made it to his room and was about to open the door when he heard a door down the hall creak open. Reed peeked out, rubbing at his eyes and yawning.
"Blaine, could you and Kurt keep it down next time?" Reed shook his head, trying to wake himself up before yawning again and walking back into the room.
I don’t think this is exactly what you wanted, but here ya go:)
