NTR: The live-in-husband gets a perverted heart system

Evening came quietly.

Tom had finally dressed and left his room only because hunger forced him to. He walked toward the kitchen with his head down, still turning over the earlier confrontation in his mind - the way Sienna had looked at him, the smear of his cum on her sleeve, the strange mix of victory and emptiness it had left behind.

He stopped short when he reached the open archway.

Sienna stood near the front entrance with a man Tom had never seen before. The stranger was tall, broad-shouldered, well-built in the way that made expensive clothes hang perfectly. He looked like the kind of man Sienna always brought home - confident, polished, and completely out of Tom’s league.

Sienna’s eyes found Tom almost immediately.

For a second she simply stared at him. Then a deliberate, slow smile curved her mouth. Without looking away, she rose onto her toes, slid a hand around the back of the man’s neck, and kissed him.

It wasn’t a polite greeting kiss.

It was deep, open-mouthed, and pointed. She made sure Tom saw the way her lips parted, the way the man’s hand settled possessively on her waist. When she finally pulled back, a thin string of saliva briefly connected their mouths before breaking.

Sienna’s gaze flicked back to Tom, cold and satisfied, as if to say: *This is what I actually want.*

Tom’s throat closed. He couldn’t find a single word. He only stood there, frozen, while the two of them walked past him toward the stairs. The man didn’t even glance at him. Sienna didn’t either - not again.

Tom turned and walked back to his room with heavy steps. He closed the door quietly behind him and sat on the edge of the bed. He already knew what was coming. He had lived through it enough times.

He wouldn’t sleep tonight.

~~~~~~~~

He was right.

It started less than twenty minutes later.

First came the low murmur of voices through the wall. Then the unmistakable sound of fabric being pulled off. A soft, feminine laugh. The creak of the bed.

Then the man’s voice - deep, calm, and already in control.

"On your knees. Mouth open."

Sienna’s reply was immediate, breathless. "Yes."

There was the soft, wet sound of her taking him in. A low, approving hum from the man.

"Deeper. Don’t stop until your nose touches me." A pause. The wet sound grew thicker. "Good girl. Stay there. Breathe through your nose."

Tom stared at the ceiling, jaw tight. His newly enhanced cock twitched against his will.

The man spoke again, still calm.

"Look at me while you choke on it. That is it. You’re already dripping, aren’t you? Pathetic."

Sienna made a muffled, needy sound around him.

A few minutes later the bed creaked heavily as he moved her.

"On your back. Legs open. Wider." The sound of skin meeting skin followed - a sharp, deliberate slap. "I said wider. Hold them there."

Sienna moaned, loud and shameless. "Please-"

"Please what?"

"Please fuck me. Use me."

"Not yet." Another wet sound - fingers, from the way Sienna’s voice cracked. "You’re going to beg properly first. Tell me what you are."

"I’m your slut," she gasped. "Your dirty little fuckhole. Please - I need your cock."

The man gave a low, satisfied chuckle. "That’s better."

The headboard began to knock against the wall in a steady, brutal rhythm. Sienna’s moans climbed higher with every thrust.

"Take it," the man ordered, voice still controlled even as the pace increased. "Every inch. You’re not allowed to cum until I say so."

"I won’t- ah - I won’t, I promise -"

"Louder. Let the whole house hear what a desperate whore you are."

Sienna obeyed. Her voice rose, broken and shameless, every cry punched out of her by the force of his hips.

"Harder - please, harder! Use me, fuck me like I don’t matter -"

"You don’t," the man said simply. "You’re just a warm hole tonight. Say it."

"I’m just a warm hole," she sobbed, ecstatic. "I’m just a warm hole for you to use. please don’t stop-"

Tom pressed a pillow over his ear. It did nothing. The walls were too thin, and Sienna had never cared about being quiet. If anything, she got louder when she knew he could hear.

The rhythm grew rougher. The wet sounds of sex filled the room next door.

"I’m close," the man finally said, voice tighter now. "Where do you want it?"

"Inside," Sienna begged instantly. "Cum inside me. please, fill me up. I want to feel it dripping out of me when you are done."

A deep, guttural groan answered her. The headboard slammed harder for several long seconds. Sienna came with him, a long, broken cry that trailed off into breathless, satisfied whimpers.

Silence followed for a few minutes, broken only by heavy breathing.

Then the man’s voice came again, calm once more.

"Turn over. Face down, ass up. I’m not finished with you yet."

Sienna’s soft, eager moan was the only answer she gave.

Tom lay awake in the dark, staring at nothing, listening to his wife get fucked for the second time that night while the System remained unusually quiet.

He didn’t sleep.

Not even for an hour.
