While your attack is solid, it doesn't really shatter the poor guy's jaw. After all, grievously injuring your poor possessed opponents wasn't your aim; freeing them on their mental shackles was! That said though, the scruffy looking hipster was certainly going to be feeling that for a while no matter what!
But of course you have more important things to think about then the one guy you've knocked out already. There was still the matter of the student and nerd, as well as the dog even if he was under your control. You quickly formulate a plan of action and execute. You send the oversized husky to run interference on the student right after you spend some time and effort to cast crush on him, encompassing him in a painful magical pressure that was akin to a whole body migraine while not truly physically damaging, at least on low levels. The dog then leaps at him, bashing into him and sending him back. The possessed student, confused, simply lashes back, striking the dog with a quickly swung fist at the dog. He hits the big fuzz ball, but doesn't make too much of an impact other then drive the dog back. In a way though he sort of set up the dog to simply leap again, and leap it does! Once again the big pup crashes against the student, this time sending him off balance and falling backward. Before he gets to the ground though his head collides with the edge of a dumpster nearby, filling the air with a loud dong. When the student finally lands he's still knocked out.
Meanwhile though your busy in throes of a more carnal combat. At first your heart isn't really in it as your mind had to focus had casting crush at the student, as well keep control on the dog, meaning the nerd gets a good twenty seconds or so to rape your pretty pussy without much struggle from you. Your heart flutters as his average sized cock(regular penis size indicates he had not been under Shadow Demon sway for very long) plunders your cunt, the demon controlling him showing considerable sexual skill despite his vessel. One hand holds your wrists tight as he thrusts, giving the cheeky guy enough time to slap your ass and elicit a sexy little squeal from you. However as soon as you put some real effort in the limitations of the nerds body become quite clear. Your flex your abs and make your love tunnel grip his tight, then you wiggle your hips and twist. The sudden intense surge of pleasure is too much for the possessed nerd to handle, and quickly you here him gasp as his cock swells. You only had a moment to decide whether you wanted him to cum inside you or not!
