No, you have another hole he needs to please first

His cock looks so cute there, twitching and throbbing desperately, begging to be touched. But there's more he needs to do for you first. You shuffle yourself forwards on his face, just enough to pull your pussy off his lips and place your asshole there instead. He does not miss a beat however, and his forked tongue starts to circle delicately around your hole, teasing it and getting it wet with his saliva. When you decide you have had enough of his teasing, you push your hips down against his face, and his tongue presses harder against your hole in response. It wriggles against your asshole, slowly worming its way inside as its touch relaxes your hole, until you can feel his tongue inside you and slightly stretching it. It is not often you have anything inside it. The demon's tongue is so soft and warm and wet, it slips back and forth inside you easily and sends the sensations of an especially naughty pleasure coursing through you.

His tongue start to thrust back and forth through your ring faster and more forcefully as he tries to build you to an orgasm, and it seems to be working. A combination of the power you have over him, the naughtiness of what you are doing, and the raw sensations he is giving you is really heightening your arousal, and you can feel your crotch quivering as you drip onto his neck and chest.

"Make me cum." You tell the incubus, and he pushes his tongue firmly through your hole, reaching the thickest width of his tongue yet and contracting its muscles to make it as thick and to stretch your hole as much as possible. It works, and you lean forward as your body pulses with such an excited orgasm, bringing your face so close to his excited and leaking cock and letting the demon whine in desperation.
