HUNTC-069 “哥哥，有个隐藏选项……我们该怎么办？” 我的妹妹就是我的哥哥，而且我还有一份高薪的隐藏选项兼职！我有个超级调皮的妹妹！当妹妹的零花钱不够用的时候……

I have a super naughty little sister! When she doesn’t have enough pocket money… she massages me and begs me for money in a sweet voice! I have no choice but to give her a light massage and 1000 yen pocket money, and she gently approaches me and whispers, “There’s also a hidden option?” I’m skeptical, but I order the hidden option! Then my sister does something naughty… Before I knew it, she’d inserted it with all the hidden options! I was completely sucked up by my sister!
