Ai Asakura plays a tale of immorality straight out of an erotic novel. A pair of still-warm shorts thrown away by a beloved cousin. A forbidden fantasy that begins with that single piece of fabric evolves into a real-life affair. While retaining the tenderness of a cousin, the moment they cross the line, they show the intense entanglement that only blood relatives can. Through the symbolic item of shorts, the passion between the two accelerates, and their secret moans overlap in the quiet of the house. A sensual work that combines literary sentiment with raw carnal desire.
