Awkward situation with jiju during festive season

Last diwali when I was changing my dress then my BIL came from back and hugged me and started groping me and whispering in my ears about he wants me.

Guys what would you do to your sister-in-law in this situation or what have you did share with me and you guys can suggest me on what to do

So wanna do the roleplay about this and willing to be open to talk about anything that you can
