[New Special Price] School Swimsuit Development Research Institute 1 Who's the JAV actress in this video? Amateur? Name revealed!

[New Special Price: 5,040pt → 1,953pt] The "Competitive Swimsuit Development Laboratory," dedicated to researching and developing racing swimsuits, has finally been established. This time, a special request arrived from someone who enjoys having sex while wearing competitive swimwear. To fulfill this request, we hired a man named Hirai, who has an identical body type, to develop the perfect swimsuit. From the initial measuring phase, meticulous measurements were taken of delicate areas including the nipples and groin. During the prototype testing phase, Hirai was drenched in lotion on a bed to test water resistance, carefully checking the swimsuit's crotch area. A unique test was conducted to ensure the swimsuit's tight fit securely covers the groin and prevents any exposure during breaststroke movements. Furthermore, using vibrators and butt plugs, the swimsuit's durability was rigorously tested. When asked for feedback, Hirai responded enthusiastically, "It feels amazing!!" indicating the design is approaching perfection. As a final check, actual sex will be performed; if no issues arise, the swimsuit will be complete. The ultimate competitive swimsuit for sex has finally been completed—Hirai himself became completely obsessed with this new sensation, fusing competitive swimming with sex like never before.
