HUNTB-387 I might be a loser at an all-boys school, but when I get home, it's a harem life with five stepsisters every day! 2 This is my secret that I can never tell my friends from school.

My secret that I can never tell my friends at school. It's that when I get home, I'm fucking with my cute stepsisters! My sister-in-law is in an environment full of women who are the exact opposite of me, so she always wants a cock! Always enjoy harem sex so that parents do not find out! However, the secret was revealed to my friend, and my friend also participated in the sex! My character, who played a sober virgin character at school, collapsed! That's right, I'm a fucking bastard! Moreover, the opponent is a super cute sister-in-law, the strongest family environment!
