FTHTD-155 Swimsuit Durability Test Institutionalized! New OLs Inspect Fabric Strength With Sex

At the sports manufacturer "FALENO TUBE FIT", an in-house system for practically testing the durability of new competitive swimsuits has finally started! The subjects are new OLs. While diligently working daily while wearing competitive swimsuits under their clothes, oil application by senior employees → insertion → piston pressure resistance testing has become an unexpected daily task. Measuring it by being thrust hard through the swimsuit! Wet and see-through, slippery insertion all the way inside! Even if they climax, time measurement continues! The evaluation targets are the degree of penetration, transparency, and how much they cum! The first mission for new graduate OLs who are betting the fate of the company on competitive swimsuits and their bodies!
