"Hey Ash, over here!" called my girlfriend, Mira. She was half-japanese, petite, and very cute, and today she was dressed in a small black two-piece bikini that highlighted her modest curves. I looked over with a small degree of lust in my eyes.

"Coming!" I called, running over across the sand to meet her. As I ran, my boobs bounced uncomfortably. How did girls deal with these things on a daily basis? ...Alright, I guess my cover's blown. While right now I am technically Ashley, that's not who I usually am. Usually I'm Matt, and not a girl. I'm just possessing Ashley for some fun while we're at the beach. Who's Ashley, you ask?

Even just the thought of it was enough to get a girl excited in a fun way. After a short time we decided to go for a swim. I hadn't been in the water in Ashley's body yet, and relished in the feeling of the cool, salty waves over my borrowed skin. We reached chest-deep water - for Mira, at least, Ashley was a bit taller than her, and Mira poked me in the boobs.

"Hey Ash, want to switch out?" she asked with a wink. I figured it was only fair at this point - I'd been Ashley for almost an hour by now. We found a nice secluded sandbar to stand on - can't be dropping the ring now, can we - and slipped off the ring. I reappeared in my own body directly …
