Of course

Duramast takes her head between his hands and pulls her closer forcing more of his still soft cock into her mouth, completely filling it. Reaching down between the demon's legs, Cinnamon slips her hands under his heavy ballsack, the two hot and heavy orbs each about as large as she can hold in a hand. Slowly the demon's huge cock begins to expand within her mouth, its bulbous head pushing against her throat as he pulls her face towards him with a slow pulsing rhythm. Soon his cock is too full to be contained within her mouth alone, its growth forcing it into her throat. Cinnamon squeezes her eyes shut, tears forming within them as she feels his hardening member penetrating her neck.

After ten seconds or so though he releases her, letting her cough and breathe against his dick for a few seconds before pulling her back on to his hardening member. It would be a shame to spoil the surprise already.
