Humiliate her further

You grab Doe tightly by the hair and she lets out a little squeal as you stand up and push her back against the wall. In her eyes you see a mix of fear and excitement. Your cock is throbbing, dripping with the thought of fucking her mouth.

She looks up at you, pleading "I think this bet's gone far enough. Please."

"Oh no" you say. "The bet was that you have to do what I say. Now open your mouth, Doe."

She looks up at you with pleading eyes and hesitates.

"Now!" you demand.

Doe reluctantly parts her glistening lips slightly and you eagerly jam your cock into her mouth. Holding her head firm against the wall you fuck her mouth. You are not holding back. You are not being gentle. You thrust your hips violently, losing yourself in the physical pleasure. You watch with pleasure as your shaft slides between Doe's pretty lips, your head popping in and out of her helpless mouth. Your hand grips her hair harder and harder, pushing her, keeping her immobile. She just sits there in front of you, motionless and helpless, taking your cock obediently into her mouth, letting out an occasional whimper or gag. You **** yourself deeper and deeper into her throat. You feel yourself approaching orgasm.

"I'm going to cum" you tell her. "I'm going to cum in your mouth."

Doe looks up at you and mumbles as if to object, but as she does you pull her head towards you and unleash a giant load into her mouth. You feel your massive dick pulsate at least 7 times, and you can feel that with each one a sizable amount of your semen is flowing into her accepting mouth. Doe mumbles in response to what now fills her mouth. She is barely able to accept the entire load.

As she tries to back away and remove your cock from her mouth you hold her still.

"Swallow it" you instruct her.

She seems completely distraught but she reluctantly obeys. You can see her taking your cum down her throat in two big gulps. Satisfied, you slide gently out of her mouth, sliding slowly along her wet lips, and resting your dick against her face.
