ROYD-104 Lazy brother and sister incest

My sister lives a very depressed life, she says she has no motivation so she is very messy. So instead of me doing the housework, I added a rule of rubbing her breasts for 3 minutes so she would be more motivated to do her own chores instead of me doing it for her, ! My sister didn't react at first, but gradually she started to feel more pleasure from me rubbing her breasts... over and over again in search of pleasure for more than 3 minutes! After that, she made me do it more often and then she made me have sex with her too.
