A new project perfect for sex-loving slutty college student Rui Airi has been launched! !! From the start of filming to the end, the cock remains inserted! An unprecedented challenge begins, where if the time without insertion lasts for more than 10 seconds, the shoot ends immediately! !! She remains inserted the whole time, even while traveling, eating, taking a bath, or using the toilet! Of course, all the ejaculations are raw creampies! The next cock is inserted before the cum from the previous one has even dried! The longest in AV history!? A controversial work with almost entirely insertion scenes has arrived! !!
