Your mind briefly recalls the sensations that had rendered you speechless before your testicles and penis transformed into their female counterparts. The same sensations suddenly erupt in your chest and you gasp. Your eyes widen and you involuntarily reach up to touch your chest. Instead of thick pectoral muscles, you touch soft tissue. You are mesmerized for a moment, until the realization that your body isn't supposed to feel like this seizes you.
The woman laughs. "Did you think the only thing that changed was your dick and balls? No, look at your shoulders, you cute little girl."
You are frozen again, shaking with the cold and with how upset you feel. Your shoulders are so much more narrow, and your arms and torso are thin. This isn't you. This is not who you entered this room as. You look at the massive door with the latch through which you entered and stagger that you ever pushed it shut. The whole world seems so much bigger and so much scarier than it ever had before. And you are completely trapped in a body that is continuing to change.
You touch your breasts, soft mammary tissue is slowly swelling, though the change in your breast is much faster than your pussy. Now that you're not staring resolutely at your own crotch, it is much harder to ignore the woman, peering at you, watching every change, and seemingly turned on at your expense. Every so often, she catches your eye, and you hate her even more deeply.
Your breasts reach what feels like a B-cup and stop swelling. You watch, hoping to sigh with relief, but instead you notice that your nipples are continuing to grow. After a minute, the areolas have enlarged across half of each breast, and the nipples are elongated and, given how cold you feel, rock hard.
The woman leans in closer. "Oh, dear, I'm afraid with nipples that large, your breasts aren't finished swelling, not by a long ways! I wonder what change will come next."
