He uses another hole. And puts a twist on things.

"What's the point? You're a worthless pig," he sneers, smiling cruelly as you sob brokenly. When you try to suck his cock again he tightens his grip in your hair and holds you away from it, slapping you when you persist.

"I don't want your dirty little mouth," he snarls. "Look at you? Slobbering all over yourself like a pig." He slaps your tits, making you squeal and sob, your mouth trembling as you whimper. "Filthy fucking whore!"

"Please...please professor...I'm begging you...please...."

"Shut up! Shut up and bend over the desk," he orders, using your hair to haul you to your feet and drag you over the desk. You whine, knowing what he's going to do, fearing your impending **** but feeling your belly fluttering with mad excitement at the idea. Your cunt is drooling juices, and you know you're wet and ready for him, overheated by his ****.

You look back, raising your rump to offer your sweet young pussy to him, wanting to be impaled and fucked more than you've ever wanted anything in your life, your independence crushed by his cruelty.

You are a whore, you tell yourself. A dirty subservient slut. You just needed a real man to show you what you are and put you in your place. You grab the edge of the desk, pressing your fat tits against the hard surface, wriggling your ass at him like the submissive bitch you are.

"Fucking whore!" he snarls, smacking your ass hard as he takes off his tie. You bite your lip, whimpering, raising your ass higher, utterly dominated by him, your cunt flowing with juice.

"Please...professor...please use me...fuck me...Please..." you whimper. "Make me take your fat cock! Make me...."

"I'll do better than that!" he sneers, looping his tie around your neck and pulling it tight as he thrusts into your dripping cunt. "I'll give you the best and last fuck of your worthless life!"

You feel the tie tightening and **** as he hammers his meat home in your trembling body. Your fingers claw at the tightening fabric as you start to shudder with degraded orgasms, whining frantically as he starts to **** you.
