Fuck his asshole

"Get on your hand and knees." You tell the demon, and he obeys your command quickly, a grinning at your new confidence. His plump and purple butt sticks up over his arched back, and you can see droplets of his arousal dripping onto the floor from his new pussy. But you're not going to use that right now.

You bend down behind him, kneeling on the floor, and point your stiff cock towards his crotch. You thrust it forward, sliding it through his legs and grinding it over the damp pussy between them, covering your cock in lubricating fluids.

"Mmmh, such a tease." The demon coos, his voice shaking a little at the pleasure you're causing him.

"Spread your cheeks." You instruct him, and he obeys your again, his face now pressing, unsupported, into the floor. His fingers wrap around his fleshy cheeks, prising them apart and exposing his dark purple asshole to you.

After rubbing your cock over his wet folds a few more times, you pull back and re-angle, pressing the tip of your cock to his puckered hole. He gasps a little, in shock or excitement you cannot tell, and then you start to push the head of your cock inside him. You're met with some resistance, even considering the juices coating your cock, but soon enough your tip prises his hole apart and you slide inside him. His hole is so tight around your cock, squeezing it hard, like it's trying to milk your cum out already, and sending pleasure soaring through your body. He gasps as the thickness of your new cock stretches his hole out, and it quickly turns into a moan as you slide his asshole down to the hilt of your cock. Then you begin to thrust in and out of his tight hole, pushing in and out of his warm insides as his ring clenches and squeezes tight along your shaft. He lets you use his body for your own pleasure, which you feel building in your crotch as you pound away as his asshole. The pussy between his legs clenches and dribbles in his own pleasure, clearly aching to have a cock inside it yet being denied it for having his ass fucked instead.

Soon, the whole experience becomes too much for you to keep control of your orgasm, and you bury your thick cock inside his tight hole, and your cock and balls pulsate as they pump this cum inside him. After several pumps it begins to drip from his hole, dribbling out around your cock. As you feel the flow coming to an end, you pull out of him, sending a wave gushing from his stretched and creampied hole and spattering more cum over his cheeks.
