You watch TV, leaving your legs spread so your woman-penis-hybrid can also watch. It's strange to think, you turned this woman into your penis, and you don't even know what her name was. Not that it matters; that name now belongs to the giant penis that's masquerading as her. You wonder if that walking penis still has genitals. You hope she enjoys your original penis, now that it's attached to her husband. Not that you were too attached to it, yourself.
Speaking of, a tingling in your loins has alerted you that you need to take care of some manly business. You make your way into the bathroom, and, without thinking much of it, you lift up the seat, aim your woman-penis down, and release urine through her mouth. By this point, you had already gotten used to peeing standing up, so aside from the strange feeling of holding a tiny person in your hand, it doesn't feel all that different peeing this way. Finishing your business, you give her a little squeeze and wiggle to release the last few drops. Then, out of habit, you grab a piece of toilet paper and wipe her mouth, and lower the seat and flush.
Curious, you lift her up and ask, "Do you like the taste of my pee? Blink once for yes and twice for no."
She blinks once. That makes sense. She's lived as your penis her whole life, as far as reality knows, so she's probably used to it. And yet, you don't know her name, or even if she has one. "Look... um... I'm having an off day, today. Do you have a name? Or are you simply known as my penis? One blink for a name, two blinks for no name."
She frowns, and after a few moments, blinks once. Well, now you feel bad. Hypothetically knowing each other your whole lives, and you can't remember her name? And without her being able to talk, it'd take quite an extensive guessing game to make her blink her name. If only there were some way to give her a voice. But, the simple fact is that penises don't talk, and at the end of the day, that's what she is.
Unless... Earlier today, she was a husband's wife, and you swapped the wife with her husband's penis, and then furthur swapped her to your own crotch. Were you able to swap her to your crotch because she's a person who is a penis, or can you swap the roles of body parts? It'd be a stretch, but...
You imagine your vocal cords swapping with hers, and press the button on your Role Swap Watch. You feel a tingling in your throat. You open your mouth to speak, but stop when you find yourself unable to. It's like you don't even know how to speak. Suddenly, you hear a small voice from below. "Why are we still standing here? We're done, there's no pee left in me."
It worked! Your penis now has the role of speaking! Quickly leaving the bathroom, you search for a post-it note, and write: "Humor me. Say your name." You then hold the message in front of your penis. After a moment, she responds "Why do you want me to say Angela?" Success! You now know your penis's name!
You prepare to role swap back your vocal cords, but hesitate. You wanted an exotic transformation. And now, not only do you have a woman who functions as a talking penis, you also no longer have the ablity (or even the knowledge) how to talk. This could lead to a very interesting dynamic.
