I attend a women's wateraerobics class every Saturday, but I'm a keener smimmer than most, so always the last in the changing room at the end. Everyone had showered and headed home by the time I went in the showers. As nobody was there, I decided to shower naked. This time, when I turned on the strong stream of water, it hit my nipple directly and made me stand back abruptly. The feeling was both a little painful and very arousing. I looked around me carefully and then purposefully positioned my nipples under the stream. I let the water assault them continuously until I couldn't deny my arousal.
Then to my surprise I began to hear quiet moans from a few cubicles ahead. The curtain was drawn, but I dared to peek in the small space between the curtain and wall. Oh what a sight! One of our girls was sitting on the floor of the shower on her side, the shower head gushing water against her clitoris and pussy, her right middle finger in her asshole, her left middle finger circling her nipple.
This image doubled my arousal, and something compelled me to reach in and rub her poor lonely nipple which wasn't receiving attention. This made her jump, but when she saw a familiar face, she let me continue. We heard a noise, so I got into her cubicle. My fingers danced casually on her erect nipples. She reached around me and began to push her finger into my ass. I took the shower head and began pointing the jets of water onto her nipples, while frantically rubbing her clit. She began to get so randy that she thrust her chest forward and spread her legs, letting me know she wants me to keep at it.
After I made her orgasm twice, she began to suck on my nipples in turn, then asked me to bend over. She aimed a strong jet of water at my asshole as she fingered my cunt. When she began to finger both holes at the same time, I circled my clit and came uncontrollably.
I think we might miss next week's swim...
