... that Kira's shaft is indeed beginning to shrink. "What... happening?" asks Kira. "Me feel... strange... me get smaller?" You can feel what Kira is feeling-- a complex combination of pleasure, confusion, and humiliation-- and watching her change is only making the feelings stronger.
"Aw, look at her," says Brooke with a smirk. "She's so tiny now." It's true. What used to be your average-sized penis is now about an inch long, and less than half an inch wide... and still getting smaller. At the same time, your balls seem to be retreating back into your body, with a cleft forming down the middle of what was your scrotum and is now rapidly becoming your labia. Through out the whole process, Brooke seems to be taking a measure of sadistic pleasure in watching her sister turn from your manhood into your womanhood.
"No!" shrieks Kira, overcome by the changes. "No... me cock... me... cock? Me... me WANT cock. Me pussy. Want cock!" The transformation slows to a stop, as what was left of your penis finally finishes reforming into a clitoris. Soon the confusion and humiliation are gone, leaving only Kira's lust to influence you. A torrent of new desires floods your mind, desires you had never considered before. You... want a cock inside you. You NEED a cock inside you.
"So how do you feel now, honey?" asks Brooke.
"Mmmm," you moan in your new feminine voice. "I'm SO horny now, babe..." You can't stop yourself. You reach your hand down and begin to dip your fingers into your brand new slit. Just as you are feeling some small bit of release, Brooke takes your hand away, saying, "No, honey. Let me help you with that."
"What do you want to do?" you ask.
"Lie down," says Brooke. Without further question, you nod and lie down on the bed. As soon as you're done, Brooke smiles in approval, and says, "Good. Just like that." And then she gets on the bed too, up on top of you, and straddles your body facing away from you. "Okay, hon...," she says, "watch me and do what I do. When you're ready for it, I want you to follow my lead."
You're beginning to understand now what Brooke has in mind-- and you can't deny, it IS really turning you on. "Okay," you say, excited.
Just as you expected, Brooke leans down from on top of you and begins to pleasure you orally-- her tongue gliding across your clit and between your labia. The feeling is AMAZING, like nothing else you've ever felt before. Kira starts moaning again. At the same time, you have a close view of Brooke's pussy as well. As Kira's yearning to be satisfied gets the better of you, you sit up slightly, and begin to lick your girlfriend's pussy in the same manner.
"Mmmm," you moan. "Oh, Brooke... that feels... sooo gooood... I... I know you don't... want me to... UUUUNGH!... to climax yet, because you want to keep... teasing Kira, but... I don't know how much more I can take... I... mmmmm... I feel so close..."
"Hold on, babe," she says, "You're almost done, I promise. I've got one more thing I want you to try."
"Oh?" you ask, gasping for breath. "What's that?"
