看这样子，是弟弟喜欢姐姐，然后被同月朋友a上去牛走了（广义牛）？

给兄弟发姐姐果照最后被牛岂不是活该…

[Synopsis]

"Yuta's sister is pretty, isn't she?"
"She's just normal..."
"By the way, do you have any sexy photos?"
"Well, I guess... I do..."
"Seriously?! Let me see them!!!"

Toshiya was one of the few friends he had.
So when Toshiya asked him to see...

This is the story of a younger brother who can only watch as his older sister, who said she had no interest in younger boys, becomes the sex friend of his playboy and sociable friend.

kinda depressing story all round for both siblings
yuta sold his beloved sister out (sending nude pics + literally wingmanning) for lunch?? and the sake of a fake friendship that didnt even last once toshiya was done, feels even more deplorable/cucky considering yuta's somewhat into her
meanwhile yuki got used as an expendable cumdump by an asshole who just wanted to fuck and move on, ig saying she's not into that stuff was bullshit if she's this loose

喜欢ntr就非得踩苦主吗？那我是不是看每个ntr前都要踩一下才能看?
