She'd broken up with her boyfriend about a month ago, that being the last time she'd had any sex. Masturbation wasn't quite the same thing, but it usu...ally was good enough to take the edge off and she hadn't even done that since the experiment had begun. There wasn't time now, she knew... maybe when she took her shower?She was the first one into the common room this morning. A bottle of wine and two glasses were on the table. One of the glasses was half full."I guess we forgot to clean up last. ‘Well, it looks like you do quite like what you’re seeing judging by the bulge in your shorts.’ I hadn’t noticed until that point that I was beginning to get quite an erection. ‘Now, that’s impressive already,’ one the girls said, ‘I wonder how big it would get if I was to show you what’s beneath my knickers. Would you like to me to show you my pussy?’ The thought of that rather hardened my cock even more and when she walked right up to me and pulled down her knickers to give me a view of her. But the reality was, should I get caught using any of them, it wouldn't really matter where I'd installed them, so I again checked, and then double checked to see if I could even see, hear or detect them when they were operating. I couldn't. Everything was set, now I had just one more thing to do, and then all I could do was wait for the next weekend to arrive.I called Steve the club president and informed him I would no longer be available for substitution as I'd be pretty busy doing something. So I got my towel out and sat down had another cigarette and a bit more wine watching folk walk past me. I turned over onto my front and got some sun on my back and feel that lovely sea breeze again.It was now time to walk back, seeing so many pert boobs, fresh vaginas and tight bottoms of my own age drove me into the sea again for a ‘ball freezer’ a couple times. That was of no use though I needed to unload again. It’s only natural after all.At this point of the beach there were only large.
