Agony with a smile! ! !Neiro Otowa, a neat and clean girl who was once active as an underground idol, stands on the stage of "Smiling Mouth Toilet", an egoistic deep throat work that forces her to endure with a smile no matter how much she gets fucked in the back of her throat.Her dazzlingly pretty beautiful girl's expression is distorted by being tortured at the back of her white throat, but because she is a masochist, she continues to pour her precious jewels from her eyes...A beautiful girl who takes such thin torture as pleasure, and continues to be crazy with a smile even in chaos.What I caught a glimpse of after her decadence was Neiro, who had fallen into a "smiling mouth urinal" that kept smiling even when her throat was raped by a phallus...
