Well it can't get any worse...

"John, I'm so sorry," Rachel gasped, her hand flying to her neck. "I didn't mean for... for that to happen."

John stared at her, his cock still twitching. "I-it's okay," he managed to murmur, his face still beet red. "It's just... I didn't mean to do that." John was so turned on by being exposed in public that his cock had not softened one bit with the orgasm.

Rachel took a deep breath, trying to compose herself. She reached behind the counter and grabbed a tissue, dabbing at the cum on her ass. "It's just, you're so... large," she said, her voice trembling. "I wanted to make sure the suit fit properly, and I guess I just got a bit too... hands-on."

John nodded, his heart racing. "It's fine," he said, trying to sound casual. "It's not like you could have known."

Rachel's eyes met his in the mirror, and for a brief moment, John saw a flicker of something in them. Desire? Challenge? He wasn't sure. "Well, you owe me one," she said, her voice a little too bright. "For the mess, I mean."

John nodded, still in a daze. "What do we do now?"

Her smile was sharp. "You're going to have to buy that suit, for starters, since you have stained it a bit. And I'll have it altered for you to make the pouch bigger." Rachel tugged the thong to the floor and John stepped out of it, so she could send have it altered.

John felt his heart drop into his stomach. "But it's...it's not..."

"I know," Rachel interrupted. "It's a little too...snug. But it's the best we can do for now. I'll have it sent out to be fixed up. It'll be ready in a week."

John's cock was still hard, sticking lewdly. Rachel's eyes dropped to it again, and she bit her lip. "You might want to put something over that." With that Rachel started to walk away, the thong in hand.

John looked around frantically, realizing he had nothing to cover up with. Rachel had taken the thong back to the changing room without giving him anything else. He felt a sinking feeling in his stomach. Did Rachel do this on purpose or was she just being careless? Either way, he was standing in the middle of the store with his dick out for everyone to see.

With a deep breath, he made the split-second decision to cover himself with his hands. His cock was too big to be hidden completely, but he could at least try to keep it out of view. He started the awkward walk back to the changing room, trying not to draw more attention to himself. But with every step, his cock slipped through his fingers, his cum acting like a lubricant.

John felt his arousal spike again. It was like his body was betraying him, enjoying the humiliation. He knew he had to get back to the changing room before he did something embarrassing, but his legs felt like lead. Each step brought a new sensation, a new wave of pleasure, and he found himself accidentally jacking himself off in full view of the store's patrons, but he couldn't seem to stop. "What's the matter with me?" John asked himself.

He turned the corner and spotted a lingerie aisle that was blessedly empty. He took a deep breath and hurried down it, hoping to find refuge from the prying eyes. His cock felt like it was on fire, and the smell of his own cum was overpowering. He tried to keep it hidden, but every step made it harder.

John was painfully aware of his own arousal. He took shallow breaths, trying to keep his breathing steady. Just a little farther, he told himself. Just a little farther and he'd be safe in the changing room.
