''Hey, want to go to the pool today?'' Rachel asked.
Absentmindedly, Naomi accepted. ''Sure'' She didn't have time to catch herself from answering. Wait, I shouldn't have said yes, she castigated herself. Maybe it's not too late to refuse.
''Great! I know you love swimming. That should take your mind off your worries'' Rachel exclaimed.
Naomi felt guilty about her friend's attentiveness. As much as she wanted to, she couldn't get herself to turn her down anymore. Still, she didn't know how she would hide her crotch. She only owned a skintight one-piece and she would clearly stand out.
''Maybe it would be a good opportunity to buy new swimsuits. My old one has been feeling tight'' Rachel proposed. Naomi's eyes lit up. She could find swimwear that could conceal her member.
''That's a great idea!'' Naomi shouted enthusiastically.
''Well, someone is eager. I didn't think you'd be this happy about shopping'' Rachel responded.
''Yeah, I can't wait'' Naomi said. It wasn't a lie. She couldn't afford to take it easy, but some relaxing time with her friend might be just what she needed.
They went to a local store selling women's swimwear.
''I already had my eyes on a few pieces here so I'll be going ahead to the dressing room. You can take your time''. Saying that, Rachel left Naomi's side.
The task seemed simple. Naomi would find some appropriate swimsuit and they would leave. However, when she entered, Naomi realized she had overlooked something that should have been obvious. The store was filled with posters of models wearing various thin clothing as well as women trying out said breezy outfits. Normally, she wouldn't have thought anything of it, but today, she struggled to find somewhere to rest her eyes on. She caught herself looking at a mature looking lady in a bikini and she felt her loins stir. She had to hurry and find something to wear. She settled on a light blue frilly two-piece. The skirt-like bottoms should hide the bulge she hoped. After trying it on and looking into a mirror, she was satisfied when she indeed looked like a normal girl. She still had to be careful not to let her penis get stiff or she would definitely get caught. As she was finishing up her purchase, she heard Rachel call to her.
''Hey, what do you think about this one?'' she inquired. Naomi looked back and she felt her heart flutter. Rachel was wearing a pink bikini with thin strings. The way the cups hugged her breasts, the way her thighs rubbed together. It was mesmerizing.
''Naomi? Are you still there?''
Naomi finally snapped out of it. ''Sorry, you just looked so beautiful I didn't know what to say''.
''Haha, that almost made my heart skip a beat. Thanks for the compliment. I guess I'll take it. Did you already find something?''
''Yeah, sorry I didn't show you''
''Don't worry about it. I would have liked to see it now, but that can wait until we're at the pool. Anything will look good on you anyway''
Her comment made Naomi blush, but Rachel chalked it up to her being shy. They eventually made their way to the pool. They had fun diving, swimming and simply hanging out. Everything went without a hitch until some kid jumped beside Rachel. Startled, Rachel let out a small cry and clung onto Naomi.
''That little midget...'' Rachel muttered. ''Sorry Naomi, I didn't hurt you, did I?'' Naomi couldn't answer back. She could feel Rachel's chest press onto hers. Their bodies were rubbing together. She had endured all this time, but these sensations were too much. She felt her prick start rising up.
''Naomi?''
''Sorry Rachel. I have to go to the bathroom'' She had no time. She rushed out of the swimming pool and into the bathroom with her hands pinning down the front of her skirt trying to avoid the gaze of onlookers. She closed the door behind her, panting.
''That was too close''
She looked at the tent forming on her skirt. It felt so cramped and wet, but somehow, she didn't dislike the sensation.
''I have to quickly take care of this and go back before Rachel gets suspicious''
Closing her eyes, she started indirectly caressing her penis from the outside of her swimsuit. She could sense it throbbing in sync with her heartbeat. She took it out of its prison and began gently stroking it. The pool water made it more sensitive and she was off into her own world. Unconsciously, she remembered the touch of Rachel's skin on her own and her sweet voice, making her shaft throb even harder. She pumped it faster and faster. She felt shameful pleasuring herself while thinking about her dear friend but she couldn't stop. Lost in her trance, she didn't notice the sound of someone approaching.
