Mason scratched his head as he watched Christy walk ahead of him. Something was off. Her hips swayed a little too aggressively, and her steps were heavier than usual. She'd been making weird comments all morning, like she was trying to be herself but kept slipping into someone else.

"Christy, you okay?" Mason asked, catching up to her as they entered their apartment.

She turned to him, her eyes sparkling with a mischief he'd never seen before. "Yeah, just feeling a bit... different today." She winked and walked into the living room, her hand casually brushing against her breast.

Mason raised an eyebrow but shrugged it off. Maybe she was just in a playful mood. He followed her into the living room and sat on the couch, watching as she paced around, her eyes darting from one corner to another.

"You sure you're alright?" he asked again, concern creeping into his voice.

Christy turned to him, a smirk playing on her lips.

"Oh, I'm more than alright, Mason. I'm fucking fantastic." She laughed, a deep, throaty sound that sent a shiver down Mason's spine.

She walked over to the mirror hanging on the wall and looked at her reflection. Mason watched as her eyes widened in surprise, and then she chuckled. "Well, hello there, handsome."

Mason's heart pounded in his chest as he realized what was happening. The face staring back at him from the mirror wasn't Christy's—it was a man's face, with sharp features, a moustache and a wicked grin.

"Who the fuck are you?" Mason demanded, standing up.

The man in Christy's body turned to him, still smirking. "Name's Peter. I'm a body hopper. And let me tell you, Mason, your girlfriend's body is a fucking dream."

Mason's mind raced, trying to process what was happening. "What do you want?"

Peter walked over to the bed and sat down, his legs spread wide, giving Mason a clear view of Christy's body. He reached up and cupped Christy's breasts, squeezing them gently. "I want to have some fun, Mason. I want to explore this body, and I want you to help me."

Mason's eyes widened in shock. "What? No! Get the fuck out of Christy's body!"

Peter chuckled, his thumbs circling Christy's nipples, making them harden under the thin fabric of her shirt. "Oh, come on, Mason. Don't tell me you've never wanted to see her like this. Touch her like this."

Mason's breath hitched as he watched Peter play with Christy's breasts, his arousal growing despite his shock. "But... but she's my girlfriend..."

Peter smirked, his hands sliding down to the hem of Christy's shirt and pulling it off, revealing her naked breasts. "And she's fucking hot, Mason. Look at these tits. They're perfect." He squeezed them again, his thumbs brushing over her nipples.

Mason couldn't deny the sudden surge of arousal that coursed through him. He knew this was wrong, but the sight of Christy's body being touched like that, the sound of her voice whispering such dirty things... it was intoxicating.

Peter stood up and slid off Christy's panties, revealing her naked pussy. He turned around and got on all fours on the bed, presenting Christy's pussy to Mason. "Come on, Mason," he said, his voice husky with desire. "Touch me. Taste me. Fuck me."

Mason hesitated for a moment, then walked over to the bed, his eyes locked onto Christy's pussy. He reached out a tentative hand, tracing the curve of her ass, the softness of her skin. He slid a finger inside her, feeling the wetness, the heat.

Peter moaned, his back arching, pushing his ass further into the air. "Yes, Mason. Just like that."

Mason's confidence grew as he explored Christy's body, his hands and mouth roaming over her skin. He could feel her responding to his touch, her breath hitching, her hips bucking. He slid a second finger inside her, his thumb circling her clit.

Peter's eyes rolled back in his head, a low groan escaping his lips. "Fuck, Mason. You're good at this."

Mason smiled, a sense of pride washing over him. He had never made Christy cum like that before. He had never seen her so wild, so uninhibited.

Peter looked back at him, his eyes gleaming with mischief.

"You know, Mason, I could do this for you. I could hop different girls, let you fuck them. Would you like that?"

Mason hesitated, the thought both exciting and terrifying. "I... I don't know. I have a girlfriend."

Peter's smile faded, a look of sympathy crossing his face. "Mason... Christy's been cheating on you. I can see her memories, her thoughts. She's been fucking other guys behind your back."

Mason's heart sank, a wave of betrayal washing over him. He had suspected something was off, but he had never wanted to believe it. He looked at Peter, a sense of resignation settling over him.

"Alright," he said, his voice steady. "Let's do this. Let's find other girls. Let's have some fun."

Peter grinned, his eyes sparkling with excitement. "That's the spirit, Mason. This is going to be one hell of a ride."
