Maybe her sister is into voyeurism
I know, that made me a bit ~uncomfy~ like, no matter how much you are supportive, spying on two people having sex (especially if one is your brother) is hmm (￣∇￣")
The sister really threw me off! I thought she was so cute and supportive but then she's watching them in secret and getting hella flustered. Does she have some type of fetish that involves her brother(￣∇￣")
