I think what is showed was curiosity not a bro complex remember the age. She is in highschool probably first year and sex is something talked about. and she has a fujoshi heart so she was curious how men did it .. remember she commented about her bro being the bottom and what he was doing. I hope this helps with some of the uncomfortableness remember keep an open mind we were all young once, I heard so many stories in highschool of kids peeking at their parents because they were curious.

Lol I have a brother but would I ever peek in on him having sex with another guy because I love yaoi? No??
Like that's so weird. That's your brother why would you even have to do that when you have free porn online to watch if you're curious or even think about his position during sex. Idk man maybe some people do that but still feels so weird to me

Lol guys cmon put yourself in the uke's shoes. Would you want your SIBLING secretly watching you have sex with your lover while thinking that you look like you're feeling goood mid fuck? Yes I wouldn't say she had any malicious intent but it's just not something you normally do?? Idk sis was acting weird
The sister chapter made me so uncomfortable
