Trained to submit

He enjoyed her rhythmic clenching and the way she moved her hips only drove his cock farther into her rectum. Soon he would be seated inside her, Alina unable to drive his cock out unless it was no longer hard. And the only way to do that would be to make him cum. Cum inside her guts. “This is so perverse, Alina. Why are you doing this to me?”

Before she could say anything her pussy became alive in pain again, her ass shooting up from a powerful jolt. “GGGGUUGHH!” She felt her anal ring stretch wide and suddenly she felt a painful popping. Her ass was high up into the air, the head of his cock firmly inside her rectum, her muscles straining hard to force out the intruder, his cock twitching each time she involuntarily clenched on his cockhead. The pain receded, only to jolt her again, her ass shooting up to engulf the head of his cock deeper into her rectum. She slumped back down, her ass cheeks clenching, humiliated as she felt the thick flesh of Michael’s sitting inside her rectum.

“I can’t help it, Alina. Why did you do this to me? I can’t take my cock out; you have it trapped inside you. What am I to do?” It felt so good, her asshole closed over the head of his cock like a tight vise, crushing it. And her muscles strained to shove him out, but once seated inside her, he wouldn’t leave voluntarily. He flexed his cock, making it jerk inside her, making her feel the thickness that was splitting up her virgin asshole. “Have you done this before, Alina?

She never felt so much shame, forcing Michael to put his cock in her ass. “Never. I didn’t even think anyone would do such a thing. Honest.” His cock twitched and jerked inside her. He would never be able to make it soft again. She was destined to have his hard cock in her ass all night long. “GGGGUUUGGHHH!” Her ass shot up, Alina bracing this time, but no amount of preparation could have stopped her hips from trying to escape the evil bite on her pussy. She was sure it was frying her. But what was worse was Michael’s cock. It slid easily on the oil rubbed on her cheeks, feeling her insides opened up to the large helmet of his cock. It stretched her virgin flesh as it pulsated and throbbed inside her. Her rectum clenched and unclenched on the rigid flesh, her anal ring stretched tight around his shaft like a tight rubber band, feeling like a baseball bat was slowly and systematically shoved up her ass, and she could do nothing to stop it.

Michael played with the switch for twenty minutes, making her take his cock slowly, savoring each groan as she shoved another inch in her virgin asshole, her anal ring so tight around his shaft that he thought it would cut off the blood supply. She pleaded for forgiveness from him, all the while his cock danced erotically in her asshole, Michael never feeling so much pleasure from a girl before. He had half of his cock inside her clenching hole, making it twitch, her asshole responding uncontrollably with gentle contractions that rippled up and down his cock. It was going to be a delightful night with this girl.

Her body was covered in sweat in spite of the damp air, Michael’s body stuck to hers. She never felt so full before, almost as if she had just ate a big dinner. His cock jerked and twitched in her asshole, Alina shamed at putting him through this terrible ordeal. Her pussy grew wet, in spite of the shocks that raced through her delicate flesh from the evil device, her clit swollen. And each time it sent new pain through her body and more of Michael’s cock into the depths of her bowels. She couldn’t believe how long and thick it was, her stomach cramping as it straightened out the bends in her intestines, his hard cock demanding. It felt as if it were alive, Alina knowing that her own muscles were making it jerk, only hoping that Michael would forgive her. It seemed like hours before she felt his abdomen on her ass cheeks. His cock jerked inside her, feeling so huge. It had to be all the way inside her, her stomach cramping from being packed from the inside. Her only hope was that his cock would grow limp inside her, relieving some of the powerful cramps that rippled through her stomach.

Whenever he jolted her, she would roll her hips as they jerked up, his cock getting such a delicious massage from her soft intestines. Each time she would think it was over, he would remind her with a new jolt, sending his cock jerking and twitching.

“I can’t take much more of this, Michael. Your cock is too big. It’s stretching me from the insides. And the cramps. I know you can feel them. It makes your cock jerk. It’s not your fault, it’s mine. I don’t know what to do.” She began to sob, the thick cock filling her guts.

“There is one way, but I’m ashamed to mention it.”

“What? Anything.” She couldn’t take having his big cock in her bowels all night long. And nothing seemed to make it shrink.

“If I came, then you could push me out.” He said it in a low voice as if ashamed to mention such a thing.

“Cum inside my ass? You want to cum in my ass?” She had never even thought of such a thing.

“I don’t want to. It’s your fault my cock is stuck in your ass. But when I cum my cock will shrink. Then it’s up to you to use your ass to shove my limp cock out.”

“Can you cum?” It was her only hope, as revolting as it sounded. To have him dump his cum into her guts.

“Not without moving. And the way we are tied, I can’t move an inch. No, you’ll have to do it.”

“Me, what do you want me to do?”

“You’ve been humping up and down like a horny dog all night. And your asshole grips my cock like a hand. All you have to do is continue what you have been doing, but try harder. I’m sure you can do it, though it might take a while. And I’ll try real hard to cum but you have to do most of the work.” Michael made his cock twitch again, enjoying the way her muscles rippled up and down his shaft.

He wanted her to fuck his cock with her asshole. She couldn’t do such a thing, it was too perverse. His cock jerked in her asshole, a new shooting pain running into her stomach. If only she could bend over to relieve the cramp, but spread to the bed she could do nothing to stop the terrible cramps. It would be hours before they would come back, Alina knew she wouldn’t last that long. And she didn’t know how long before the evil device would bite into her pussy again. She concentrated, using all of her power to squeeze her asshole. She felt his cock shudder inside her. She pulled down, feeling his cock pull about an inch from her asshole before she settled back down, his thick cockhead pushing deep into her guts. “Like that?”

“Yes,” Michael said excitedly. “Exactly like that. Roll your hips as you do it. Yeees, that feels real good. Keep that up and I’ll dump all my cum in you.” Michael began to relax, letting her do all the work, her asshole nipping at the head of his cock as she began to fuck him.

She was sweating as she gripped his cock with her asshole, humping up the few inches she could move before she had to settle back down, the thick head of his cock expanding her virgin anal passage as it pushed back in. All the while her body was braced for the pain of the evil device pushed against her pussy, waiting for the pain that she knew would come. It was so perverse, Alina fucking a strange cock, not in her pussy, but up her ass. And she began to get a strange tingling between her legs, her pussy rubbing on the thick device between her lips. Even though she was bracing for the pain, she also felt the masochistic thrill of the device sliding up and down her wet slit. And part of it was riding over her clit, making it swell in pleasure. She couldn’t believe that her body was feeling these perverse thrills from such a revolting act. And his cock felt so full in her ass, her stomach cramping on the thick head each time she forced it back inside her. She almost wished his cock was in her pussy.
