Your soft-spoken mousy babysitter comes into your room to have a conversation. At first she's worried she's in trouble for something. You quickly reassure her that's not the case. In fact, you have an idea to help her. You've noticed that she lacks self-confidence, and you want to help boost her esteem. You work at a pharmaceutical company, and you've designed a new supplement. It enhances the female breasts when consumed for a short time- also increasing confidence. When she hears about your idea to test the product, she agrees. At first the intense growth spurt worries her, but once you've assured her she's safe-- she becomes more aware of how aroused you are at the site of her massive new breasts. So excited to be looked at in a lustful way, she decides to let you take her new body for a ride
