Luke sneakily takes Emma's bra, hoping to transform later.

As Emma turned her back to Luke, sorting through her laundry, Luke's gaze was drawn to the lacy black bra peeking out from her basket. His heart pounded in his chest, the temptation to take it and explore his new power further was almost too much to bear. He glanced at Emma, her hourglass figure swaying gently as she moved, her CC breasts shifting beneath her low-cut top.

Luke made his decision. He reached out, his hand trembling slightly as he snatched the bra from the basket. He quickly stuffed it into his pocket, his cheeks flushing with a mix of excitement and guilt.

Emma turned around, holding a pair of her jeans. "You know, you should really be more careful with the clothes," she said, not noticing Luke's flustered state. "Some of them are delicate."

Luke nodded, trying to act normal. "Yeah, you're right. I'll be more careful," he said, his voice barely concealing his nervousness.

Emma shrugged and turned back to her laundry. Luke took this as his cue to leave. He grabbed the rest of his clothes and hurried out of the laundry room, his heart pounding wildly.

Once in the safety of his bedroom, Luke locked the door behind him. He pulled the bra out of his pocket, his fingers tracing the lacy fabric. He could feel his heart racing, his breath coming in short gasps. He knew what he was about to do was wrong, but the temptation was too great.

He quickly stripped off his clothes, his eyes never leaving the bra. He slipped it on, the cool fabric sending a shiver down his spine. Almost instantly, he felt a warmth spread across his chest. He looked down, watching in awe as his flat chest began to swell, growing into the full, round breasts he had seen on Emma.

Luke couldn't help but let out a soft moan, the sensation of his new breasts was overwhelming. He cupped them, feeling their weight and softness. His nipples hardened under his touch, sending a jolt of pleasure straight to his groin. He could feel himself getting hard, his cock straining against his boxers.

He turned to his mirror, his eyes widening at the reflection staring back at him. He saw Emma's breasts, her hourglass figure, her everything. He ran his hands over his new curves, marveling at the softness of his skin, the dip of his waist, the flare of his hips.

He slipped off his boxers, his cock springing free. It looked almost obscene, jutting out from his new feminine form. He wrapped his hand around it, the sensation of his own touch almost too much to bear. He began to stroke himself, his eyes locked on his reflection.

He watched as his new breasts bounced gently with each stroke, his hips bucking slightly as pleasure coursed through him. He could feel the pressure building, his body tensing as he chased his release.

But just as he was about to come, he heard a noise outside his door. He froze, his heart pounding in his chest. Had someone heard him? Had they seen him? He quickly grabbed his clothes, his body still trembling with unspent desire.

Option 3 - Luke tries to cover up his new body and answers the door.
