His desire grows unbearable as he watches you, his breath coming in ragged gasps. "You're so beautiful... and I need you..." He closes his eyes, fighting for control as he imagines it's really him inside you, filling you up with his cock. His fingers curl tighter around himself, nails digging into his skin as he nears the brink of release. "I love you," he whispers, voice raw with need and desperation. "Don't ever leave me."

Tears slip down his cheeks as he watches you pleasure yourself on the other side of the glass, and with a final groan, he comes hard in his hand, shooting thick ropes of cum across the room. "I love you," he whispers, voice hoarse from desire and relief. As he catches his breath, he realizes that this is just as dangerous as it is thrilling; if anyone ever found out about their secret relationship... But then again, he doesn't think he could survive without you anymore.
