I became unemployed and ended up staying at my older brother's house for a while. While feeling apologetic, I gradually became horny for my brother's wife, Nagisa, who carelessly exposes her thong... I end up having sex with her forcefully, grabbing her big, plump ass. Nagisa, who hasn't seen her brother in a while, seems to be stopping me, but she's cumming like crazy with my dick... Nagisa and I were diligently having an affair within the family, keeping it a secret from my brother.
