“Teacher, I’m an adult now.” A teacher reunites with his former student Sayaka after ten years. When she says she wants more time to catch up, she leads him straight to a love hotel. He is rattled by her seduction at first, but her sweet whispers in his ear break down his restraint and draw him into forbidden sex. The diligent, innocent student he remembers has grown into a voracious woman who promises to satisfy him better than his wife and keeps making him cum all night.
