What else is there to do? You turn on the shower and start jacking off furiously, while your memory of the experience is still new and clear. You close your eyes and try to recall with perfect detail what it felt like, smelled like, and particularily, tasted like, to be a vagina. After a few moments you stop, consider the soap on your hand, and reach for the stone sitting on the counter.
"I wish for a bottle of good lube."
And you continue. Unsurprisingly, you bring yourself right to the edge in no time. But acting slightly out of character, you stop. Instead of finishing right away, you think of the possibilities. You now posess the power to turn what was an impossible fantasy into reality, and with that power comes both potential, and danger. What if you messed up, and made the wish permanent? The thought of being stuck forever as a pussy makes your cock twitch happily, but you know that it would be a bad idea. Probably. What if the "random woman" you had been made a part of had been in a situation much, much worse than a ride on the bus? What if she had been someone related to you? Or very old?
You sit on the shower floor, letting the water run over your head. This could be complicated. But then, with a flash of inspiration, you pick up the rock which you left on the soap shelf.
"I wish that whenever I wish to become a woman's gentials, the resulting experience is something I would enjoy."
The rock glowed faintly for a second, and happy with your wish, you put it back on the shelf.
With that out of the way, your thoughts turn to the possibilities, as you start to grow hard again in time with your quickening heartbeat. You have only experienced a very, very small part of what it must mean to be a pussy. What would it be like to be the vagina of a woman who was jogging? Taking a bath?
Without noticing it, you begin to stroke yourself again.
What about being a shaved pussy? Or one on a bike ride?
You're going faster now, your eyes close.
And, oh god, you're too horny to pretend that you wouldn't like to know what it was like to be a cunt that was getting eaten out, riding someone's face, getting masturbated, or even getting fucked,
You realize what's about to happen but it's too late, as you blow your load in the open shower air. You can usually keep quiet but this excitement is too much, and a moan escapes you. Finally, after a couple of seconds, your pulse starts to come back down. Looking around, you assess the damage, you're going to have to do some cleaning before you leave. Oh! Right. Quietly chuckling to youself, you pick up the stone again.
"I wish this shower was clean."
