Men's underwear does not get much sexier or unusual than the Hidden Underwear O Ring Bikini-Thong. What is a bikini-thong you ask, well it's a men's bikini brief with a rear thong shaped panel sewn into the rear of the bikini.
The Hidden O Ring Bikini-Thong is a super skimpy bikini brief that is very low-rise on the waist. The front is super low with a ring that pulls the two waist sections together to create an opening above the pouch. The pouch has a slight contour and hugs your manhood to create an impressive bulge in a close fit that leaves the front of your legs bare. The rear just about gives full coverage sitting high on the sides of the bum cheeks. The middle panel is shaped into a Y-shaped thong shape, but because its a part of the bikini rear it doesn't fully sit between your bum cheeks or leave them bare. But what it does do is pull the rear tight against your bum to create a close fit.
They are made from a lightweight and see-through mesh that is constructed with a microfibre mix of 94% Nylon / 6% Spandex. The pouch is opaque to give you a bit of modesty but the rest is completely sheer mesh.
If you're looking for sexy see thru mens sheer mesh underwear that is a bit different then these mens bikini brief could be for you. But beware these bikini briefs are super skimpy.
