I summoned a demon-girl...

I closed the door to my room and locked it, and inscribed the protection circle on the floor. Strands of magic went out in infinite-dimensional geometries and brought, and trapped, a beast that had sky-blue skin and massive breasts and long bat wings. Though fully mature as a demon, she was only half my height, so that when she stood she was at blowjob height without kneeling. Her long tail circled around her ankles. She was completely naked.

If you're summoning a demon, you don't choose an intelligent one. Intelligent demons are a bad idea. For the obvious reason. She easily submitted to my will, and I released her from the protection circle.

I commanded her to lay back on my bed, and I spread her legs and started licking gently. It was a standard human-vagina setup, except far more responsive and it tasted like Coca Cola. I liked it, and she wrapped her legs and tail around my head, pulling it closer. She moaned and humped my tongue and as I sucked on her clitty, she came, spraying me with pussy-juice that also tasted sweet.

All that had gotten me horny, so I stood her on the ground and unbuckled my pants, and grabbed her black hair and rammed my cock into her mouth.

She wrapped her wings about my waist and her tail came between her legs. She humped her tail and teased my ass with the very tip of it, sending a shudder of good feelings. And the blowjob was excellent, as she stroked my long cock with both hands and sucked most of it.

An orgasm was building, of course, but I flexed the magic that could hold it off, so that I could enjoy my sex **** in other ways.
