Frank went to bed first, kissing Ellie goodnight, then clapping Marco on the shoulder on his way out. His hand lingered there for a second, his fingers pressing into the muscle, and he gave Marco a look that was hard to read in the dim light.
“Sleep tight, kid,” Frank said.
Then he was gone up the stairs, and Ellie was still there, and Marco was standing in the living room with the ghost of Frank’s hand burning into his shoulder.
Ellie stayed up a little longer, making small talk, asking Marco about himself. Where he was from. Why he left. He didn’t tell her much. She didn’t push.
When she went to bed, she paused at the bottom of the stairs and looked back at him.
“Goodnight, Marco,” she said. That soft, melodic voice that made his chest ache.
“Goodnight, Ellie.”
She smiled and went upstairs.
Marco lay in his bed for a long time, staring at the ceiling. His body was still warm from where Frank’s hand had been, and his head was full of Ellie’s voice and Ellie’s smile and Ellie’s smell. But underneath all of that, there was Frank. The weight of his hand. The way he’d looked at Marco before going upstairs. The easy confidence of him, the way he moved through a room like he owned every inch of it.
He thought about what Ellie had said. Open relationship. Don’t be scared.
He wasn’t scared.
He was something else entirely.
Marco woke up with a dry throat and a hard-on.
The dream was already fading. He could feel it slipping away, the edges dissolving, but he knew it had been about Ellie. Her face, her voice, her body. And Frank. Frank’s hands on him, Frank’s mouth close to his ear, that low voice saying things Marco couldn’t quite make out. Something had happened in the dream, something that made his pulse race and his cock ache, but he couldn’t remember what.
He lay there for a minute, staring at the ceiling, trying to catch the dream before it disappeared completely. It was no use. It was gone, but the feeling stayed, heavy and warm in his gut.
His throat was parched. He needed water.
He pushed back the covers and sat up. He was wearing just his boxers, and his erection was obvious, tenting the fabric. He thought about taking care of it, but he didn’t feel right doing that in someone else’s house. Not yet.
He got up and opened his door. The hallway was dark, but there was a faint light coming from downstairs. He walked toward the stairs, and that’s when he heard it.
Moaning.
It was coming from the master bedroom. The door was closed, but it didn’t matter. The sounds were clear enough. Ellie’s voice, low and breathless. The rhythmic thump of the bed frame against the wall. A deep grunt that had to be Frank.
Marco stood there in the hallway, his heart pounding, his cock still hard, and he knew he should go back to his room. He knew he shouldn’t be standing there listening to them. But his feet wouldn’t move.
The moaning got louder. Ellie said something he couldn’t quite make out. Frank’s voice rumbled in response, low and commanding, and the bed thumped harder. Marco could hear Frank’s rhythm in it, the steady, deliberate pace, and something about that, the control of it, the authority, made his cock twitch.
He shook his head. He turned away and forced himself to walk down the stairs. He wasn’t going to stand there like some creep. He was going to get some water and go back to bed and not think about what was happening in that bedroom.
The kitchen was at the end of the hall. He found a glass in the cabinet and filled it from the tap. The water was cold and tasted like minerals, and he drank it down in long gulps. Then he filled it again and sat at the kitchen table.
He thought about everything that had happened. The job. Ellie’s touch on his chest. Her knuckles on his chin. The way she’d said investment. Frank’s hand on his shoulder. The wink. The fingers on the back of his neck. The open relationship comment. Don’t be scared.
He wasn’t scared. He was confused.
And horny.
He sat there in the dark kitchen, the glass of water in his hand, and tried to sort through it all. But his thoughts kept circling back to Ellie. Her face. Her voice. The way she’d looked at him like he was something she wanted.
And Frank. The way Frank looked at him, the slow appraisal, like he was something worth looking at. The casual touches that weren’t casual at all. The way he’d sat so close on the couch, his leg warm against Marco’s, his fingers on the back of his neck. The sound of him now, through the ceiling, that low grunt, the rhythm of his hips.
Marco took another drink of water and tried to calm down.
That’s when he heard the footsteps.
He looked up. Frank was walking down the hallway toward the kitchen.
He was completely naked.
