ROYD-159 Hinako Mori, a slender big-breasted older sister who sweetly nurtures the boys she picks up so that they become obedient dicks that will listen to your naughty wishes.

I am kept by a rather plain but beautiful office lady. When I get home, I'm a troubled person who takes out all the stress I've accumulated at work. In order to further relieve her frustration, she trains her dick to her liking every day! Only I know what she looks like! It's a lot of trouble, but I'll be sad if I'm not here, so I think I'll stay here for a while.
