A lesson they won't forget (Patreon)

Sachiko has seen two students bullying her little sister a lot lately and decided to take care of that in her own way...
When the two were by themselves, she shrank them before taking with her home. As she entered her bedroom, she threw the two students on her bed and removed her shoes and stockings before sitting on the bed. She order the two bullies to clean her feet as a punishment. Not only hers, but her little sister's feet as well as an apology...

I'm sure they learned their lesson very well XD
