Ease your cock inside him

You stroke your hard cock with one hand as you hold him down with the other. Precum leaks from the slit, and you smear it along your fingers until they're dripping. Easing two fingers between his clenched cheeks, you rub against his tight anus, slicking that ring of muscle with your own slippery fluids. He makes strangled sounds, his struggles leaving him out of breath and gasping around the gag.

"Easy, master," you murmur, pushing two fingers inside him. He sobs, his body going limp as you push deeper. He's trembling, shaking with each gasping breath he takes. His puckered entrance clenches around your fingers, then relaxes. You work your fingers in and out of him, spreading the precum and stretching his opening.

Curling your fingers forward, you press into the wall of his rectum, feeling for his prostate, and he gasps, bucking when you find it. You rub against that spongy lump, making him moan and writhe.

You add a third finger, thrusting deep, and he arches his back like a cat in heat, moaning around the gag in his mouth.

"You like that, master?" you ask, pulling your fingers out. "Then you're gonna love this." You take your cock in hand and rub the knob up and down his crack before pushing against his rosy opening. He draws a sucking breath and squirms, tightening to keep you out. "Don't do that," you advise him. You feel a very un-demon-like stirring of sympathy for your frightened master, and you lean over him, pressing a soft kiss to his spine.

"Don't fight me," you murmur against his skin. "I don't want to hurt you." He grows still and you can feel him trembling beneath you, listening, but not relaxing. "You said you trusted me, remember? Trust me now. Push back against me, let me in. It will feel so good, I promise."

He says something into the gag that ends in a sob, and you hesitantly reach for the ragged strip of cloth.
