The IKingsky brand of men's thong underwear is some of the skimpiest out there and features, a small sleevelike pouch for your penis and balls. It is available on eBay see

The pouch fits quite snug and depending on your condition it may be difficult to get everything you want to have inside into the pouch.
The back is another issue as it consistes of a very narrow elastic band that in the SM is shorter than in the MED and LRG. THe short size means that the back needs to cinch up tighter between the glutes.
Spending the night in an IKingsky thong.
I did this last night and had great fun. The first puzzle is how to get the penis and balls both completely inside the pouch. With respect to the penis, think of the pouch as something of a "masturbation sleeve" and you will quickly become aware that the cloth of the sleeve is something of a "containment device". Having a penis inside a containment device such as a realy tiny thong is always fun.
But the back is part of the fun too, especially a short, narrow back such as IKinsky SM. You are being hit with the sensations from being inside the pouch, but also with the cinching up that occurs when the back is a little too short. It is the combination of sensations that you are getting. The constant tension of the back of the thong complements the sensations from the sleeve-like pouch.
What to wear over? If you want you can wear something over all of this with a snug swim brief being the obvious choice. The thong becomes a swim brief liner of sorts.
Last night I found a pair of short-and-snug compression shorts in an interesting black and white camo pattern. These added to the fun I was having down there with the sensations from the tiny thong, I spent the night wearing both and awakened feeling horny as all get out. I particularly enjoyed the tension provided by the thong back all night long.
I think others might enjoy trying this too, I could suggest other items such a a strap and cup but I will leave that for another day,
