AQSH-106 Even after marriage, she's so into her big-brother that she forgives anything and is easy to push around, big-breasted little sister Hoshino Natsuki

When my husband goes on a business trip and leaves the house empty, my favorite brother who lives in our hometown suddenly comes to Tokyo. My brother, whom I adore, proposes using an empty room, and I decide to take advantage of his kindness. When I ask him the reason for coming to Tokyo, he says it's because he broke up with his girlfriend over sex, and he wants to improve his sexual techniques at a brothel. However, the target prostitute had quit, so my brother, at a loss, proposes using me as a practice partner, playing on my personality. Unable to refuse my beloved brother's request, I end up reluctantly agreeing.
