Slowly, taking a long time to cum

Duromast decides to take it slowly, enjoying the velvety soft texture of her mouth and throat while she dutifully sucks him, even letting her control the depth and speed at which she's taking him. Though she's an expert cock sucker it's clear she's having trouble getting used to the size of his cock. Her lips are stretched tightly around the hard shaft, and she winces in pain every time her neck bulges, the outline of his cock clearly visible with every thrust. Now that it's grown to its full size she's only able to take less than half the length of his cock, for the moment at least. Part of the process of breaking her in will be getting her used to this.

After about half an hour though of letting Cinnamon practice her deepthroating skill on him, Duromast feels that it's time to really give it to her. Reaching down the demon wraps one hand around her bulging throat and balls his other in her short hair. Then, giving her a savage yank pulls her small body onto his cock, sinking it deeper down her throat than she's been able to by herself. To Cinnamon's shock though he keeps going, her eyes flying wide open as she feels his cock begin to impale her completely, bursting through the tight ring of flesh at the bottom of her esophagus and into her stomach.

Finally, with her lips stretched nearly to the point of splitting and her lips resting just above his ballsack, Cinnamon realizes that Duromast has stopped moving. He's just holding her there with a cock as big as her arm filling her throat. Weakly she taps his thigh, trying to get his attention, but in response the demon slaps her across her cock stuffed face growling, "**** on it."
