"What the fuck!" Max's voice echoed through the bathroom, the sound of the showerhead hitting the tiles drowning out the panic in his tone. He looked around, but the room was empty except for the steam that danced around him. "This isn't funny, asshole!"
The invisible force took hold of Max's body, bending him over as if someone had grabbed him by the waist. Max felt the sensation of something thick and unyielding pressing against his backside, and before he could process what was happening, it was inside him. He yelped in surprise and pain as it pushed in deep, stretching him beyond his limits. He tried to struggle, to push against the unseen invader, but his muscles felt like they were made of jelly, useless against the relentless force that was claiming him.
The water cascading down his body did little to ease the discomfort, instead acting as a strange lubricant as the phantom cock slammed into him over and over. Max's eyes squeezed shut, and his knuckles turned white as he gripped the shower rail, his breath coming in ragged gasps. He could feel every inch of the invisible shaft moving within him, and the sensation of being so thoroughly filled was overwhelming. Despite the fear and the shock, a strange heat began to build in his stomach, coiling like a serpent ready to strike.
He tried to reason with his attacker, to scream for help, but the only sound that came out was a muffled whimper as the force pushed deeper. The water was now mixing with sweat that beaded on his forehead, trickling down his face and chest as the pace grew more frenzied. The pain morphed into something else, a burning pleasure that he hadn't anticipated, and his body started to respond to the intrusion in ways he never thought possible. His own cock grew hard, slapping against his stomach with every thrust from behind.
Max felt his knees begin to buckle, but the force kept him upright, impaling him without mercy. His thoughts swirled in a whirlwind of confusion and arousal. He knew this was wrong, that he should be terrified, but his body was betraying him. The pressure in his balls grew, tightening like a fist, and he knew he was close to climax. It was as if his body was being controlled by an entity with its own agenda, and all he could do was submit to the pleasure that washed over him like a tidal wave.
His leg was lifted, and Max felt the phantom grip move from his waist to his ankle, holding him in place as the rhythm of the invisible force grew more erratic. It was as if it knew exactly how to hit the spot that sent sparks of pleasure through him, each thrust pushing him closer to the edge. The heat in his stomach grew more intense, coiling tighter and tighter until he thought he would combust from the inside out.
With a guttural groan that seemed to come from the depths of his soul, Max came, his semen spurting out and mixing with the water as it rained down on him. The force didn't stop, though; it kept moving, driving him to another peak. The pleasure was so intense it was almost painful, each wave crashing over him like a breaker on the shore. His body was a live wire, every nerve ending alight with sensation, and he couldn't help but moan, his voice a strange mix of pleasure and despair.
Max's legs gave out at a particular hard thrust that made him see stars. His body hung in midair, his ankle still held by the invisible force as it continued to pummel into him. The water continued to fall, now cold, only adding to the overwhelming sensations as it hit his sensitive skin. Max felt his body convulse with each relentless pump, his muscles tightening around the ghostly intrusion. The pleasure was so intense it was almost unbearable, a rapture that seemed to go on forever.
The force's pace quickened, and Max could feel the tension building within the unseen phallus inside him. It grew thicker, stretching him even further, and the sensation was indescribable. He was on the brink of a second climax, his mind reeling from the sheer power of his body's response. The room spun around him, and he gripped the shower rail even tighter, his knuckles now white with the effort to stay conscious.
