BTH-042 Because you're always so full of energy... I want you to smile even when you're crying. Aoi Rena

Film Introduction

The endearing smile of a beautiful girl twists into an expression of agony each time her throat is brutally penetrated, causing her to uncontrollably drip saliva as a defensive reaction. Even in this state, she is ordered to 'smile while deepthroating!' and isn't allowed to stop suffering even in her hazy, confused consciousness, being forced to endure and bear the pain with a smile even as she nears suffocation.
