Brooke finishes washing up, keeping you both excited by rubbing you occasionally in what feels to you like your face. You can't see anything, not even yourself, but judging from the level of sensitivity and the intensity of the pleasure you feel each time she touches you there, you deduce that she must in fact be rubbing your clitoris... or, her clitoris, really. The feeling of warm water trickling down your skin is adding to your enjoyment. Gradually you start to feel yourself involuntarily swelling, as you hear her moaning over the sound of the shower.
Suddenly, the shower goes silent, and you feel the steady stream of water washing over you stop. Without it, the air around you feels cold, and for a moment you feel helpless to protect yourself from the draft. After all, you're just a vagina... what can you do? But Brooke must be able to sense you shivering, because a few moments later, you feel her pressing you all over with a towel, trying to get you dry and warm once more. For the first time since making the choice to put on the silver ring, the realization truly hits you-- now that you're Brooke's pussy, you're going to remain as her pussy until she decides to turn you back. You have absolutely no control over yourself. You understand now, why the clerk at the magic shop mentioned the importance of trusting each other.
"Brooke?" you call out to her without speaking.
"Don't worry, honey," she says back as she continues drying herself. "I promise I'll turn you back when I'm all done with you. It was really sweet and really trusting of you to give me my turn without me asking, and I'm going to respect that. I just want to give you a good ride first."
"Thanks, Brooke," you answer. "Uh... How did you...?"
Brooke snickers. "I can feel pretty much everything you're feeling, remember? I could feel that you were getting a little nervous." Her tone once more takes on a playful and seductive tone. "But I have the perfect way to relax you." She rubs you again, this time plunging her finger inside you once more. The feeling is pure bliss. Whatever concerns you had seconds ago are gone in an instant, replaced by an instinctual desire to have the space inside you filled. That is all that matters to you in this moment.
When Brooke is done drying off, you hear the sound of the bathroom door opening, and feel her walking out. With each step she takes, you feel the movement of her thighs on either side of you, gently pulling and caressing you. Just as you start to enjoy it, she stops, bends forward a bit, and you can hear her say, "Where is it?"
"What are you looking for?" you inquire.
"Ah, here it is," she says, not fully answering your question. "I knew I had one in my purse." She turns and walks the other direction, until you finally find yourself stopped once more. This time, you can tell, you're lying down. You must be back on the bed. You feel Brooke spread her legs. "Here you go, hon. Tell me what you think of THIS."
"Think of wh--" you start to ask, until you hear a soft humming sound and feel something else touch you-- first your clitoris, then your lips. Finally, you feel Brooke separate your lips with her fingers and put it inside you. You've never felt anything so amazing in your entire life. Whatever it is that Brooke has used to penetrate you is buzzing all over, sending a torrent of energy through your entire being... stimulating you more and more with every... vibration...
And that is when you understand what is happening. The thought is enough to make you wet once more, this time with your own fluid. Brooke is using a vibrator on you.
