Thanks to my sister, I do naughty things every day with my sister's colleagues. The older sister is a hikikomori and obeys her younger brother's orders. I don't want to go outside, but I have a sex drive more than anyone else's order to do an AV... 1

My older sister doesn't want to go outside, but she has a sexual desire that is greater than anyone else, and she absolutely obeys the orders of her younger brother. He is forced to rent an AV, and finally, he is used to relieve his sexual desires by handjobs and blowjobs...but his younger brother's demands become more and more radical, and when he orders his sister to have sex with another woman... the sister calls out to his colleagues at work, and as instructed his younger brother to drink a drink containing sleeping pills, forced to put him to sleep in a state of drunkenness. Her younger brother appears and rapes the unresisting women as they please!
