Halfway through playing the game, the joystick suddenly broke. I was angry about why the game couldn't be played. Suddenly I heard my sister yelling in the living room. However, I found that the joystick in my hand could not control the game...but it could control my sister...!? Still a virgin? I have been interested in my sister's good figure for a long time, so I controlled her buttocks to come in front of me and rub my big stick until she couldn't help but have sex with her sister!
