This intense production focuses exclusively on extreme anal stretching. We've carefully selected the most stimulating footage, including anal self-fisting, anoscopic examinations, gaping, massive anal plugs, and double penetration with dual-headed dildos, all designed to push anal pleasure to its limits. In PART2, the theme centers on experimental anal relaxation techniques required to achieve full anal fisting. Performer Miko Oba appears as the test subject, demonstrating the entire process of expanding her anus to the absolute extreme. Discover a groundbreaking new approach that deepens the depth of anal play.
