Reluctantly...

John's mind raced. He thought he might have heard that before. John reluctantly went back into the changing room and slipped off his trunks and boxers, quickly putting the suit back on without any underwear. John once again stepped out of the changing room to get Rachel's opinion.

"There," she said, her voice a little shakier than before. "Much better."

John felt a strange mix of embarrassment and arousal knowing because Rachel knew he wasn't wearing any underwear, which is crazy because that's how you wear swimsuits. He didn't know what to say, so he just nodded and silently thanked her.

"No problem," Rachel said, her eyes sparkling with something that might have been amusement. "Let's go out and check the mirror, shall we?"

John followed her out of the changing area, his shorts tenting obscenely in front of him. Rachel led him to a three-way mirror, and John couldn't help but feel like everyone in the store was staring at him. He knew that wasn't the case, but his embarrassment was palpable. Rachel stepped behind him, her hands on his hips.

"Turn around," she instructed. "Let's see how they look from all angles."

John turned, feeling Rachel's fingers tighten slightly. He caught his reflection in the mirror and felt a jolt of shock. The shorts looked like they were about to burst open, the fabric stretched taut over his swollen cock. Rachel leaned in closer, her breath hot on his neck.

"Hmm," she murmured. "They look pretty good, but we should check the fit in the back."

Her hands slid around to his ass, her fingertips grazing the top of his butt as she adjusted the waistband. John's cock twitched, and Rachel giggled again.

"What's the matter?" she asked, her voice a symphony of sweet innocence.

John's eyes widened as he saw the tip of his cock peeking out from the shorts. He hadn't even felt it happening, Rachel's ministrations had been so distracting. He tried to push it back in, his face burning, but Rachel's hands were faster.

"Oh dear," Rachel said, her eyes wide with feigned shock. "It looks like we'll need a bigger size after all." She gently tucked John's erection back into his suit, brushing the head slightly as she did.

John's cock had never been more apparent than it was at that moment. Rachel's touch had sent waves of pleasure through his body, making his erection impossible to ignore. She stepped around him, her eyes never leaving the floor as she made her way back to the racks. John's heart was racing as he tried to process what was happening. He knew that Rachel had to have seen his arousal, but she was acting as if nothing was out of the ordinary.

Rachel returned with another pair of board shorts. "These are a bit larger," she said, holding them out to him. "Why don't you try these?"

John took them from her and retreated back into the changing room, his mind racing. Each time Rachel had touched him, she had made it seem like it was necessary for the fitting process, and he had been too overwhelmed to argue. He took a deep breath and stepped out of the shorts, his cock standing at full attention. Rachel's touch had been electric, and he couldn't get the feeling of her hands on him out of his head. He slipped into the new pair and stepped out of the changing room.

Rachel took one look at him and her eyes lit up with mischief. "Much better," she said, stepping closer to him again. "But we should still make sure everything is in place and will stay that way."

Her hands found their way to his hips, and she began to make minor adjustments, her fingers grazing his skin lightly. Rachel's hair brushed against his leg as she worked, and he could feel the heat of her breath on his thigh. She straightened up and met his gaze in the mirror, her eyes twinkling.

"Looks good," she said, her voice low and seductive. "But we should make sure it's not too tight anywhere."

Her hands moved to the front of the shorts, gently pressing against his cock. John gasped, his hips involuntarily thrusting forward. Rachel's cheeks turned a deeper shade of pink as she pretended to inspect the fabric.

"They're definitely a better fit," Rachel said cheerfully, but a little too loudly.

Her hands slid around to the back of his shorts, her fingers lingering near his ass. John felt his cock throb with anticipation. Rachel leaned in closer, her breasts brushing against his front as she whispered in his ear.

"But we should really make sure that everything is...secure," she said, her voice dripping with innuendo.

John's heart was hammering in his chest. Rachel was playing a game with him, and he had no idea how to respond. He felt her hand slip into the back of the shorts, her fingers sliding over the curve of his ass before settling on the waistband. She tugged gently, ensuring that the shorts were snug enough.

"Perfect," Rachel murmured.

John's eyes darted to the mirror, watching as Rachel's hand hovered near the front of his shorts. She gave the waistband a gentle tug, pulling it back just enough to create a gap. His cock was now partially exposed, the purple tip peeking out like it was begging for attention. Rachel's eyes flickered down for a second, but she quickly looked away, pretending not to see. John's heart was racing. He couldn't believe she was doing this, and even more shockingly, she was making it seem like it was all in the name of customer service.

"Let's just make sure it's not too snug," Rachel said, her voice a little too sweet. She stepped closer, her hand reaching out to touch the fabric at the base of his shaft. The sensation of her fingertips was electric, and John had to bite his lip to keep from moaning. Rachel's eyes met his in the mirror, and he knew she felt the tension building between them. Her other hand moved to his side, her fingers brushing the fabric just above his hip.

"Oh no," Rachel gasped, her eyes going wide. She took a dramatic step back, her hand flying to her mouth. "I'm so clumsy!"

John's eyes followed her gaze to the floor where her phone had slipped out of her pocket and lay face down. Rachel bent over to pick it up, her crop top riding up and exposing her toned stomach. She had the most amazing ass, and John couldn't help but stare as she bent down with her legs straight, the fabric of her leggings stretching tightly over her firm cheeks. He could see the outline of a thong, a tiny strip of black that disappeared into the crevice of her ass. The sight was almost too much to bear. John's cock throbbed at the sight in front of him.

As Rachel straightened up, her eyes flicked down to his waistband. John felt his heart stop when he realized that the head of his cock had popped out of the shorts. Rachel's eyes widened slightly before she schooled her expression back into one of professionalism. She turned away, her cheeks a little pinker than before.

"Looks like I'll need to get you another size," she said, her voice a little higher than usual. "I can see why you have so much trouble finding a suit. Why don't you go back to the changing room while I grab a different pair?"
