Negatively

Figuring your body has already changed enough with the addition of a penis, you shake your head, telling the doctor "Honestly, I think I'd prefer to leave as I am."

She seems a bit disappointed, but nods regardless, and walks over to the table. Quickly undoing the straps with practiced hands, you find that you're able to move again, a brief soreness around your wrists and ankles the only adverse effect of the bondage. As the doctor turns to you, you can't help but feel your cock twitch with arousal, her bare breasts still on display but somehow slightly more noticeable than before, as her lab coat hangs open to reveal slightly more of her bust.

Once you can stand, painfully aware of your nudity, you cross over to the chair in the corner and pick up the lab coat from where it was discarded, sliding it onto your shoulders. You move to button the front, which the succubus had earlier instructed you not to do, but find that you can't- there aren't any buttons on it. Denaria seems to be back by the table with glass vials, jotting down some notes, and takes little notice of you.
