Katahira Yurina plays a masochistic woman. Her first attempt in life is the forbidden "anal exploration." The moment a massive cock penetrates her tight sanctuary, she screams with a mixture of shock and pleasure. Her capacity collapses in an instant as she is penetrated in both her vagina and anus at the same time. Her bewildered expression gradually changes to the unique pleasure of anal penetration, and she transforms into a pervert, drooling and begging for further abuse. The uncensored reality meticulously records the milky liquid spilling from her gaping anus and her devastated, soulless face.
