She lay with her breasts on his belly, still stroking his cock with her hands. His cock was now eighteen inches long and throbbing stronger than ever. Without stopping stroking it, she slipped her knees off the bed and stood up. She circled around to the foot of the bed.
At last she stopped stroking. He whimpered at the ceasing of the pleasure. She crawled onto the bed from its foot, up between his legs. She caressed his enormous cock with her breasts, up and down the length of it, and he whimpered again, in delight.
Then she began to kiss the end of his cock. She suckled it, licking and caressing with her tongue. Slowly, she began to take it further and further into her mouth. It looked far too long, but she kept going, kissing down to the base, as his shaft slid into her throat.
His pleasure had risen to an all new level. His cock was throbbing as if ready to burst, but he did not yet come. He writhed on the bed, as much as the chains would let him, moaning in ecstasy.
She slid his cock in and out of her throat and mouth. Faster and faster, rushing excitedly towards his climax, just about there, just about there, yes, yes, yes, she bit hard into his cock!
He screamed at the agony. She chewed and bit and munched, his eighteen inches turning into mince meat in her mouth. Through the middle of it, he could feel his ejaculation, spurting with all the unleashed sexual tension. Squirting pangs of pleasure, marred by the pain as he felt every inch of his cock being shredded.
At last, she knelt up. Her breasts were still gorgeous, but his eyes were caught by her mouth, full of crooked, sharp, black teeth, oozing with blood and cum.
He sobbed and wailed, as the pain continued, gradually easing to a dull ache. Between his legs was just a small ragged remnant of flesh, with blood oozing down to add to the stains on the sheet.
She turned and climbed off the bed, showing her slim, firm backside. She walked back to the chair, and sat in it like before, gradually turning back into the hag.
The pain was almost gone now. His cock was starting to heal, growing back just slowly enough that he could not quite track its progress. He knew that sometime after it was restored, this would all happen again, as it had already happened, more times than he could remember.
Chained to the bed, naked, he stared at her.
