Minami-chan is a good cousin's daughter who was raised with care by her parents who had strict professions. They go to cram school every day and struggle to create a future that lives up to their parents' expectations, but humans are not cyborgs. Children don't grow up the way their parents want them to. What she developed in her heart was an overwhelming interest in meat sticks. When she gets stressed out from studying, she searches for men on apps and offers her vagina for a decent amount of her pocket money. What can you call this, other than calling it a stain on your life? Well, I'm lucky so I'll let you cum inside me.
