Competitive Swimsuits: Endurance Testing Institutionalized in the Company! New Office Lady Tests Fabric Strength in the Crotch Area Through Sex at a Sports Manufacturer Ashina Honoka Nishino Emi Saeki Renka Fukuhara Mina

Sports manufacturer FALENO TUBE FIT has introduced a unique new company policy: real-world endurance testing of newly designed competitive swimsuits! The test subjects are new female office workers, who must wear the swimsuits during daily operations while undergoing special evaluations conducted by senior employees. After coating the body with oil, testers slowly penetrate the swimwear and perform repeated piston-like pressure tests—turning the task into an unexpected in-house event. The wet swimsuits become translucent, clearly revealing penetration through the fabric. Even after reaching climax, the inspection continues, assessing key points like fabric tightness, transparency, and orgasm intensity. For these new graduate office ladies, their first job is an unusual challenge where corporate success hinges on swimsuit performance and physical response!
