Summary
“Right, he wanted me to tell you he hopes you feel better soon, or something like that.” Kaeya shoves the toy further inside, and Diluc sobs louder. “I wonder what he’ll say if he sees you like this, or finds out that you’ve been like this for the entire time you’ve been away from school.”
He leans in, closer to Diluc’s ear. “I bet he’d love it,” he whispers. “Maybe he’ll ask to try you out on the spot. Maybe he’ll ask to stop by every day to play with you.” Kaeya firmly grips the prostate massager, then cruelly shoves it as deep as he can. Diluc screams and thrusts his hips up into the air, as though he’s trying to escape the stimulation, but Kaeya easily follows his movements.
“What if he decides he wants to keep you, too?” Kaeya knows he’s being irrational when his own words anger him further and further, but he can’t bring himself to stop. “What would you do if he took you away from me, to lock you up in his bedroom instead?”
====
Or, Kaeya hits his breaking point when his own best friend makes a move on his perfect brother, decides it's time Diluc is taught who he belongs to, and starts by tying him down to his bed.Series
