She was dressed just for the occasion...

"Okay," Rachel said, her voice low and conspiratorial. "I have an idea." She glanced around the store, ensuring they were alone. Then, without warning, she lifted her t-shirt over her breasts.

John's eyes almost fell out of their sockets. Rachel's breasts were a perfect handful, her nipples a dark pink and already hard with arousal. They bounced slightly as she moved, and he couldn't tear his gaze away from them. Rachel's stomach was flat, her waist cinched in, and her hips flared out in a way that made John's mouth water. She had a small tattoo of a butterfly just below her belly button, and it fluttered slightly as she moved closer to him.

"This might seem a bit...unorthodox," Rachel murmured, her eyes gleaming with mischief. "But I really need to make sure this suit fits perfectly in any situation. And to do that, I need to make sure you're...fully aroused."

John's brain was screaming at him to run, but his body was rooted to the spot. Rachel's tone indicated that she was slightly embarrassed to bring up John's erection, but her actions told a different story. Rachel's breasts were so close, he could almost feel the heat radiating off of them. His cock was now fully erect, straining against the confines of the g-string. Rachel noticed and gave him a knowing smile.

"It's okay," she whispered, her hand reaching out to cup him firmly. "Let's just get this over with."

Her other hand reached out and began to stroke him through the thin fabric, her touch feather-light. John's breath hitched, and he couldn't help but lean into it. Rachel's breasts were mesmerizing, her nipples standing at attention. He felt like he was in some kind of trance, unable to think, unable to speak, unable to do anything but stand there and feel Rachel's actions.

Rachel's eyes never left his as she worked her magic. She stroked him slowly, her thumb flicking over the head of his cock. John struggled to keep control, his hips moving in time with her hand.

And then Rachel stopped. "Alright," she said, her voice business-like once more. "Let's see if that was enough." She stepped back, her eyes running over his body like a sculptor admiring her work. "I'm just not sure if you're fully erect. It's hard to tell like this..."

"What do you mean..." John started to question, but he was cut off mid sentence.

Without warning, Rachel tugged the g-string down in the front, causing John's erection to pop free. His eyes snapped to hers, a mix of shock and arousal. "I'm really sorry, John," she said, her voice a purr. "But every time I've ever felt or an erect cock, it's been out in the open, skin on skin. I just couldn't tell with the material in the way."

John's mind raced, trying to process what was happening. Rachel was...about to jack him off? In the middle of the store? But her reasoning made a twisted sort of sense. Why would she know what a hard dick felt like through clothes? She was just being thorough. That's definitely what was happening.

Rachel reach out and firmly grasped John's throbbing cock, her hand moving slower now. She watched him in the mirror, her eyes narrowed and her lips parted slightly. John could feel his orgasm building, but it remained frustratingly out of reach. Rachel's touch was incredible, but it was the thrill of being exposed, the danger of being caught, that had him on the edge. He gritted his teeth, his body straining for release.

"I'm pretty sure I'm hard, Rachel," John rasped out with great difficulty. "I think you can stop."
