BAGR-080 - Sexual abuse of younger female cousins in Tokyo (BAGR-080)

My younger cousins, Rio and Amu, came to visit my house. They want to stay at my place to save on accommodation costs. Amu is polite, but Rio has a habit of looking down on me quite a bit. I've been taking care of them since they were little, so I guess it can't be helped. But of course, I don't look at my younger cousins sexually!? Amu has large breasts, and Rio is slender... I don't look at them like that!? But I'm looking forward to them coming. I should tell them a lot about Tokyo as their older brother.
