``If you don't mind... can I cum for you?'' I am bothered by the sounds of my brother and his wife having sex every day when they come into my house, and I finally reach the limit of my patience and have a wet dream. Even more tragically, he was discovered by his niece Hikari. I can't help it if I'm pathetic. However, I can't let days like this continue, so I have to take advantage of the opportunity... Just as I was thinking about this, I came across a proposal for my niece's sexual treatment. Half of it was because I was sorry, and half of it was because I was interested in her sexuality. Despite my resistance, I was able to shake off the limiter and accepted this proposal, and a strange relationship began!
