Percy might not be experienced, but he was a guy and he knew what Cass was doing. He propped himself up on his elbows and glared at Cass, although he was sure that the effect was ruined by the need in his face and voice. "If you don't stop teasing, I will hex you and no one will ever find proof of it."
He wasn't sure if it was the threat, or what else, but Cass moved except- "Fuck... oh God, Jesus." Percy hadn't expected that, because it was dirty and disgusting, and oh my God, he was going to die. "Cass... please... fuck, please." He knew he wasn't saying anything, but how was he expected to think. He always pushed sex to the side, never important, never irrelevant, expect to jerk off on some morning to take care of the need, but now he couldn't go through the motions. It wasn't enough. "Would you fuck me already?" he blurted out with typical Gryffindor impatience.
