Most girls know their place and are happy to be face fucked and slapped around these days. As they have become used to this treatment, we need to up our game. My suggestion: cum in the slut’s eyes. Don’t just aim at them. Hold them wide open and cover her eyeball in semen. A full load of cum in her eyes will degrade her in ways she never thought possible. Warning: this will cause her considerable pain for many hours afterwards, but it is safe and won’t injure her.
