ZUKO-073 The boss's daughters have been trained to be erotic and are used for making babies

You were tasked with taking care of his daughters due to your brother's business trip. ●Bright and lively girls, as you take care of them, you gradually notice something strange. These girls have been trained in sexual acts by their perverted brother without even knowing it's wrong. Naturally, they want to bathe together and, calling it 'sticky-sticky,' innocently beg for sex. Some have pubic hair, others don't, but you keep pouring your 'juice' into them anyway. What a tough day.
