"Close your eyes, honey," she says with a mischievous smile. "Don't open them until I say. I want this to be a surprise."
At this point, with Kira's ravenous libido influencing your own, you're pretty much willing to do anything so long as it results in an orgasm, so you quickly comply. In the meantime, you run your hands up and down your own breasts. It still feels strange to have them; the fantasy has crossed your mind before, briefly, but you never imagined you'd ever ACTUALLY be able to experience being a girl firsthand. After what seems like a few minutes with your eyes still closed, you ask, "Brooke? Baby? Are you still there?"
"I'm here," she replies. "Are you ready?"
You nod again. "Mm-hmm."
You feel Brooke gently put her hand on your inner thigh. Suddenly you hear an electric buzzing. You have scarcely enough time to figure out what Brooke's surprise is, before you feel a pulsing cylindrical object sliding into your vagina. The sensation is pure ecstasy. "You can open your eyes now," Brooke says. As you do, you already know exactly what you're going to see-- and you aren't disappointed. For the second time today, Brooke has put her vibrator inside you.
"Yes! Yes!" shouts Kira in your head. "Me pussy! Need cock! Harder! Deeper! Unnnnggghh!!"
You can't stop yourself anymore. Brooke moves the vibrator in and out, penetrating deeper into you. Instinctually you begin thrusting your pelvis and moaning wildly, all the while still rubbing your hands over your nipples. There is no distinction between Kira's pleasure and your own anymore. You're completely lost in the moment. "Oh, Brooke... oh, oh, oh, yes... it's happening... I'm... I'm about to..." All at once, before you can even finish your sentence, you feel the orgasm send shivers through your body. Simultaneously, you and Kira cry out in joy.
When it's all over, all the tension in your body is released, and you're left lying weakly on the bed. Through breathless gasps, Kira manages to say, "Mmm... so good... me tired now... me... go sleep..."
"So how was it?" asks Brooke, pulling the vibrator out from Kira's lips. Though Kira has fallen asleep, the excess fluid is still dribbling out of her.
"That... was incredible...," you say, breathing a sigh of relief.
