"Come on, Brooke," you whimper, as you realize you could be stuck as Brooke's pussy for much longer than you expected. "Stop playing around. This isn't funny anymore."
"I'm not trying to be funny," replies Brooke, in what to you sounds like a flippant tone of voice. "You know, I've gone along with a lot of things you wanted to do that didn't particularly interest me. Remember that comic convention we went to last summer? Or all of the times we've gone to the theater to see some superhero movie you wanted to see? I really appreciate that you volunteered to pay for these rings. That was very sweet of you. But... for once, honey, I have complete control over what we do, and I'm going to enjoy it for a little while. Don't worry, I'll have fun with you in a little while, I promise. And afterwards, I swear, I'll switch places with you to make it up to you. I just want a little taste of autonomy for a change. Just a few hours where you have to go along with me while I do what I want to do. Is that so much to ask?"
Thinking about it, you start to feel like perhaps Brooke's request isn't all that unreasonable, even despite the fact that she has literally turned you into her vagina and proposed to keep you that way until she gets what she wants. "Fine," you finally sigh. "I guess this... isn't the worst thing. It's a little stuffy in here, and I honestly preferred when you had your panties pulled down, but I guess I don't mind waiting for a little while. Where are you going to take me?"
"Hmm...," you hear her respond. "Well... hehe. Considering I have your wallet now... I wouldn't mind heading over to the mall and buying myself something nice..."
You're a bit annoyed that she's dipping into your wallet now for something else besides just the rings, but under the circumstances, you realize there's not really anything you can do to stop her. Besides, while you're in this state, it's probably best not to antagonize her. Calmly, you answer back, "Alright, alright, fine. Just don't bankrupt me, okay? I expect to still see some money in my wallet when you turn me back."
"Word of honor," she replies giddily. You can tell she feels excited, as if she's getting away with something naughty. All you can do right now is imagine the things you'll be able to do to get even with her while she is your dick.
Just as you begin to envision the fun you could have were the tables turned, your train of thought is interrupted by the sensation of being in motion. Once again, you feel the insides of her thighs softly rubbing up against you on both sides, causing your sensitive form to shiver with delight. "B-Brooke? What's happening? I can't see where we're going..."
"I'm just going up front to pay for the rings, like we said," says Brooke. "Don't panic." She walks out of the back room, up to the counter, and you hear her say, "Alright, miss, we're all finished testing out those rings. We'd like to buy them, please."
Then you hear a faint laugher, coming from someone else, followed by the familiar feminine voice of the clerk from before. "Ah, so I see you are still wearing yours. I trust he is... comfortable?"
"Um... yeah," says Brooke nervously. "As comfortable as he can be, considering the circumstances, I mean."
"I must admit, the Transference Rings are among my favorite items in the shop as well," says the clerk. "I have used them several times myself. They can be... quite satisfying, when used properly. A little word of caution, though: I do not advise wearing them for more than six hours at a time."
"Why not?" you hear Brooke ask.
"Because they are very powerful magic," says the clerk. "After a while, the person wearing the silver ring will start to undergo a mental change. Especially when he becomes aroused. But so long as you take them off and give them a rest before six hours have passed, there is no reason for concern, I assure you." There is a brief pause, and then the clerk adds, "That will be $15, please."
"Wait... what do you mean, a 'mental change'?" you try to ask. But of course, the clerk cannot hear you, and therefore does not reply. Brooke pays the money, and after a few moments, she is heading for the door to go out to the car, with the clerk courteously saying, "Thank you. Please come again soon!" as she leaves.
After another twenty or so minutes in the car with Brooke, you hear her put the gear in park and feel her exit the vehicle. "Alright," she says. "We're at the mall. I won't be too long here, honey. I promise."
"What exactly are you looking for here, anyway, Brooke?" you ask.
You hear her chuckle a bit, before explaining, "Well..."
