My brother suddenly opened a sister brothel. And not just any brothel—it specializes in girls with glasses and huge breasts. What on earth is his reason for doing this? I can't understand his logic at all. How dare he use my big tits without permission to make money? I'm definitely getting my cut—every last yen from private bookings, extra services, and extension fees. Still, renting such a luxurious apartment... does he actually expect customers to show up? What exactly is going through his mind? He doesn't seem to have any plan at all.
