Frank fucked him harder. Right in front of his own wife. The same wife he shared with the young man he was fucking.
“Oh God ... so good.”
Each thrust was deeper now, more deliberate, and Marco could feel the rhythm of it in his bones. The bed was creaking under them, the headboard hitting the wall, and the sound of it was obscene, wet and raw. Marco was making sounds he’d never made before. Gasps, moans, little whimpers that came from somewhere deep inside him.
“That’s it, kid” Frank said. His voice was rough, strained. “Take my cock. Take it.”
Marco looked up at him. Frank’s face was above his, his dark eyes intense, his jaw clenched. Sweat was beading on his forehead, dripping down onto Marco’s chest. Frank’s hands were on Marco’s hips, gripping hard, and every thrust pulled Marco onto his cock. It was too much. It was everything. Marco couldn’t think, couldn’t breathe, couldn’t do anything but feel.
Ellie was right there. Her face close to Marco’s, her hand on his chest, and she was watching, her eyes wide, her lips parted. She was breathing hard, so turned on it was radiating off her in waves.
“You love it, don’t you, baby?” she whispered. “You love my husband’s cock inside you.”
Marco didn’t answer. Couldn’t answer. But his body answered for him. His cock was rock hard, leaking pre-come onto his stomach, and every time Frank thrust into him, his cock jumped, and a wave of pleasure went through him. He was moaning, and he couldn’t stop.
“I asked you a question,” Ellie said. Her voice was sharper now. Demanding. “Do you love it?”
Marco swallowed. His throat was tight. He looked at Ellie, then at Frank, and he nodded.
“Yeah,” he said. His voice was barely a whisper. “I love it.”
Ellie smiled. That hungry smile. “Say it louder.”
“I love it.” Louder now. More certain. “I love Frank’s ... your husband’s cock inside me.”
Frank groaned. His hips jerked forward, and he slammed into Marco, and Marco yelped, and his back arched off the bed, and the pleasure was so intense it was almost pain.
“Fuck,” Frank said. “You’re so tight, kid. So fucking tight. I love your ass. Ellie, watch ... I’m fucking him. Look at him. So beautiful.”
Ellie moved, and before Marco could process what was happening, she was straddling him. Her knees on either side of his hips, her pussy hovering above his cock, and she reached down and grabbed him.
“I want to feel you inside me while he fucks you,” she said.
She lowered herself onto him. His cock slid into her, and she was wet, soaking wet, and she gasped as he filled her. Then she was sitting on him, his cock buried inside her, and Frank was still inside his ass.
Marco was being filled from both sides. The sensation was overwhelming.
Ellie started moving. Riding him, slow at first, and every time she slammed down, it pushed Marco’s body down onto Frank’s cock, and Frank thrust up, and Marco was caught between them. It was too much. It was everything. He was drowning in sensation.
“Oh god,” Marco said. “Oh god, oh fuck.”
“That’s it, baby,” Ellie said. She was moving faster now, grinding on him, her hands on his chest, her breasts bouncing. She looked incredible, wild and beautiful and lost in it. “Take both of us. Take us both.”
She was the center of it. Even now, with Frank inside him, with Frank’s cock driving into him from below, it was Ellie who held him. Ellie’s eyes on his. Ellie’s body around him. Ellie’s voice in his ear. Frank was the force, the pressure, the thing that made him gasp and shake. But Ellie was the center of gravity.
Frank was fucking him harder now. His rhythm was faster, more urgent, and his hands were gripping Marco’s hips so hard there would be bruises tomorrow. Marco didn’t care. He wanted the bruises. Wanted the marks. Wanted to feel this tomorrow and every day after.
“You’re my little slut now,” Frank said. His voice was rough, commanding. “You know that?”
Marco gasped. The words hit him like a punch, and he should have been offended, should have pushed back, but he wasn’t, and he didn’t. He was something else. Something that wanted to hear more.
“Okay,” Marco said. “I’m your slut.”
Ellie moaned. Her pussy clenched around his cock, and she rode him harder, and her breathing was fast, and she was close. Marco could feel it, could feel her getting tighter, wetter.
“Fuck him, Frank,” she said. Her voice was breathless, desperate. “Fuck his tight little ass. Make him yours.”
Frank slammed into Marco. Hard. Deep. Marco screamed, and his body bucked, and Ellie had to grab the headboard to stay on. Frank did it again, and again, and Marco was losing his mind, losing everything. There was nothing but this. Nothing but Frank’s cock inside him and Ellie’s pussy around him and the pleasure that was building and building and building.
Ellie came first. Her whole body seized, and she threw her head back, and she screamed, and her pussy clamped down on Marco’s cock. He could feel her coming, feel the wetness, feel the spasms, and it pushed him over the edge.
He came inside her. His cock pulsing, filling her, and his ass clenched around Frank’s cock, and Frank groaned, and his rhythm faltered, and he slammed in one last time and held.
“Fuck,” Frank said. “Fuck, fuck, fuck.”
He didn’t come. Marco could feel it, feel Frank’s cock still hard inside him, still throbbing. Frank pulled out, and Ellie climbed off, and Marco lay there, spent and trembling. He didn’t know what was happening.
Frank stood at the edge of the bed. His cock was hard, glistening with lube, and he was breathing hard, and he looked at Marco with those dark, hungry eyes.
“We’re not done,” Frank said. “Not even close.”
Frank sat back on his heels. Marco lay there, trembling, his body still processing what had just happened. His ass was sore, his cock was softening, and his whole body felt like it had been turned inside out.
Ellie rolled off him and lay on her side, catching her breath. She looked at Frank, then at Marco, and her expression softened.
“Hey,” she said to Frank. “Give him a break. Maybe until tomorrow.”
Frank stared at her. “What?”
“You heard me.” Ellie propped herself up on her elbow. “Give the kid a rest.”
