Its after school Your heading back to class and when you enter you see nanjou and another boy going at it she's not naked only her lingerie is visible her shirt is unbuttoned and her panties are visible. They stop and the boy leaves bumping you with "thanks alot dude" you glance back at nanjou she's looking at you with awkward eyes and has the audacity to ask you "would you like to go on from where we left?" What's your next move
