Adam enters while Mia hides

They left within twenty minutes.

Adam drove. Mia sat in the passenger seat with her skirt already hiked up, panties pulled to the side. Two fingers worked inside her cunt in slow, steady strokes. The wet sound filled the car. She was soaked from the video, from the texts, from the thought of what was waiting in that empty house. Every time Adam shifted gears his eyes flicked to her lap. She didn’t stop.

“She’s going to be in that bed,” Mia said. Her voice was low. Her fingers curled. “On my side. Touching herself because she thinks you’re coming to fuck her alone.”

Adam’s hand tightened on the wheel. His cock was hard in his jeans. He didn’t answer. He just drove faster.

Mia pushed a third finger in and moaned, quiet, head tipped back against the seat. Her free hand gripped the door. The house was twenty minutes away. She kept herself right on the edge the whole drive, never letting herself cum, just staying open and wet and ready.

When Adam turned into the driveway he killed the engine. The house was dark except for one light upstairs. The bedroom.

He looked at her.

“Stay behind me,” he said. “Don’t speak. Don’t make a sound until I tell you. You watch. That’s it.”

Mia nodded. She pulled her fingers out. They shone. She wiped them on her thigh and followed him out of the car.

The front door was unlocked. They went in quiet. Up the stairs. The hallway was the same as it had been years ago. Adam stopped outside the bedroom door. It was cracked. Soft sounds came from inside. Wet. Rhythmic. A low moan.

He pushed the door open and stepped into the frame.

Melissa was on the bed. On her back. On Mia’s side. Tank top shoved up. Panties gone. Two fingers buried in her cunt, pumping. Her other hand was on her clit. She froze when she saw him.

For a second neither of them moved.

Then Melissa smiled. Slow. She didn’t cover herself. She spread her legs wider instead, fingers still moving, and looked at him standing in the doorway.

“You came,” she said. Her voice was breathy. “I was starting to think you were just going to leave me like this.”

Adam leaned against the doorframe. His eyes stayed on her hand. On the way her cunt gripped her fingers. On the shine running down to the sheet that used to be Mia’s.

“You said you wanted me to fuck you on that bed,” he said. “I wanted to see if you meant it.”

Melissa’s fingers slowed but didn’t stop. She circled her clit, hips lifting a little.

“I meant it. I’ve been thinking about your cock since you texted me. About you walking in and just taking what you want. About you holding me down right here and fucking me until I can’t talk anymore. About cumming in me on the side of the bed she used to sleep on.”

She pulled her fingers out. They glistened. She held them up so he could see, then brought them to her mouth and sucked them clean while she watched him.

“You going to stand there all day?” she asked. “Or are you going to come over here and put that cock in me?”

Adam didn’t move yet. He just looked at her. At the open, wet cunt between her thighs. At the way she was still touching herself, slower now, waiting.

“You sure?” he said. “Once I start, I’m not stopping because you change your mind. I’m going to fuck you how I want. On that bed. And you’re going to take it.”

Melissa’s breath caught. Her fingers pressed harder against her clit.

“I’m sure,” she said. She spread her legs wider and crooked two fingers at him. “Come here. Fuck me. Show me what Mia’s been getting that she doesn’t deserve.”

Behind Adam, in the dark of the hallway, Mia stood perfectly still. Silent. Watching. Her hand was between her own thighs again, two fingers sliding through her wetness while she looked at her stepsister on the bed, legs open, asking for her husband’s cock.
