Lara Swift is Colonized, Ch. 4: Stable Vices (Patreon)

Lara develops a seriously embarrassing masturbation habit, that the Black Hole uses against her. She is re-introduced into her classroom in a diminished position, where she begins learning about the other girls in this place. 

But she just can't stand Miss Galkowska's terrible requests, and earns a terrible punishment to get her to comply to their ridiculous demands.
