My little step-sister was punished because she had sexual relations with his step-brother.

My room is decorated in all pink with pink bed too. I’m punishing my step sister as she was having a sexual affair with her step brother, I caught her having sex with him and now I’m punishing her cause of that. I have tied her legs and hands and blind folded her. I have removed her panties as well; she is just wearing a pink top. Her legs are spread wide open and she’s got a nice pink pussy. I get a whip lash and start to tease her slowly while lashing and hitting her on her thighs. She starts to moan with pleasure, while I’m slapping her ass with it and playing with her. Her pussy is so wet and it’s clear that she’s craving for a cock so badly now but there’s nothing she can do other than to moan and get only this pleasure. I give some gap to let her think and worry as to what I will be doing next as it would help to bring in the pressure for her while I hit her hard on her stomach, she shouts as it is giving her pain and pleasure as well. This is how I ended up punishing her.
I must punish my litle step sister where it hurts the most and with which she made sin.
But small pinky sister enjoys even in punishment and she laugh when I whiping her vagina with whip.
