Woah, more imoutos (for a different onii-chan)

 

[Carcer]

Heart eyes? Look out, this one is horny.

Is this fourth sister the scrapped one? From what I remember on the chapter notes I thought she also had pink hair.

No this is an entirely different sister and brother pair
also this chapter got uploaded out of order and takes us way back to just before chapter 22, the chapter where the main brother is suffocated in Koharu's swimwear clad chest for staring at another girl's boobs
that other girl is actually this green haired girl. (the author confirmed this detail for me)

The brothers all look way too similar

 

[RajioSalmon]

It's like looking at Koharu and Onii-chan if it was some kind of alternative universe where moral roles are reversed.

All these brothers with their busty bro-con sisters, and here I am all alone
