However, instead of looking for a room, she spends all day lounging in the room and playing games! Angry, the brother tries to make his sister dislike him and leave by groping her exposed breasts without any defense!... But, 'Go ahead and grope as much as you like, just let me stay here a little longer.' To his surprise, she responds this way! As the brother's demands escalate, the sister becomes increasingly lustful and aroused!!
