Hypnosis v1.2a Win/Mac/Android+WT by Expanding Universe - Adult Sex Game

Overview:

You moved in with your best friend and his family under one condition:
That you don't hook up with your friend's cute little sister Leah who seems to have a crush on you.

The game begins with Leah complaining that her boobs are too small.
To make her feel better you pull out your grandfather's pocket watch and wave it in front of her, telling her that her boobs will grow.
This somehow works, and soon all of Leah's friends are asking you to hypnotize them also.

The game is less based on mind control than the title suggests, as the hypnosis is used more for body transformations such as giving the girls more curves.

There are five main girls with storylines to explore romantically, each with additional friends to introduce you to.
