Hesitantly

A brief nod from you is all the encouragement the doctor needs, and she claps her hands, clearly pleased you won't be leaving unchanged. After several more seconds, she returns to your table with a new set of syringes in hand, and again quickly injects them into your arm, chest, and just above the groin. Warmth floods your body as it starts to change, your weight shifting from some of the pronounced muscles and shoulders of the male form, flowing into a pair of expanding breasts and widening hips.

Your groin changes, but not as much as you necessarily would expect, as the twin balls shrink and disappear into your skin. Seconds after, the smooth skin under your penis splits, opening up into the familiar warm walls of your pussy. The final shifting of your face signals the end of the transformation, in a way, and you're left again as a woman, albeit with a flaccid cock lying between your legs.

"See? You look so damn cute, don't you think? Did you want to revisit some of our earlier transformations, or stay as you are now?" The doctor's tone picks up when she suggests the first option, clearly excited to work more changes on your body.
