My sister, who attends the Japanese salon, was helped to apply oil, and I was getting an aroused and erect, and my massage plan was just barely sensual.

My new sister, who was born after my parents remarried, is treated like a child, perhaps because of my appearance, which is often seen as a younger person, and sometimes uses me with my chin. I was disliked by her very gal and flashy girlfriend. When my sister, who is tanned, always orders me to apply aftercare oil when she gets home from the salon. I reluctantly listened to what I said, but I started to feel aroused by the wet and shiny body after applying oil... My sister, who thinks I'm an insignificant child, doesn't seem to doubt her when she touches her shady side. So I used to give an erotic massage, taking revenge for my sister who always uses her chin.
