Rollo is used to being in control and he panics so hard when he can't hold back desires he didn't even know he had. And in front of who? The mage he hates?
Every time after returning to consciousness he feels so guilty for his words he had uttered while riding the giant dragon dick, so dirty because of his vulgar body covered in sperm and his own wetness...
His shoulders are decorated by bites that don't have time to heal, hips bear claw marks, the scent is so obviously messed up by their frequent sex that the students of Noble Bell would've called their beloved president a whore if they could sense it. Rollo feels like a whore himself. The more Malleus fucks him, the more his body responds and gets wet from the slightest provocations
