When I returned home after a long time, my sister had completely become a "mojo" (unattractive woman). She used to be the type that men flocked to, but now she's just shut herself in her room, obsessed with games and anime. With messy hair, glasses, and sloppy loungewear, she's completely fallen into otaku culture. Yet, she still treats me like her "underling." Whenever she can't hold back her arousal, she summons me with a "come here right now." The moment I open the door, she silently drags me in and uses me like a tool for sexual release... In the end, multiple rounds continue until morning, and my sister looks satisfied...
