Normally D-rings are used for more "rugged" uses such as: rock climbing, heavy lifting, or possibly towing but it may be time to add Male Power's Extreme thongs to the list.
High quality materials and craftsmanship were put into this exotic mens thong.
With a barely there waistband and tear away front pouch you are left almost au-naturale.
Perfect for intimate fetish role-play or maybe to work under a suit for you naughty boys out there.
