A luxurious collaborative production made to celebrate MAX-A's 30th anniversary. One lucky customer, selected from participants of the popular adult event "Ero Oyaji," is invited to MAX-A's 18+ harem house. Upon arrival, they are greeted at the door by five stunning actresses who immediately perform blowjobs. Next, heading to the bath to wash off, Mamao offers a special service. In the kitchen, Hatano and Hibiyon serve handmade dishes while delivering erotic pleasures. Finally, all five actresses and the customer unite for an intense, soaking wet 6-person sex session filled with squirting, concluding this lavish experience.
