Tucking. Proper tucking requires shoving your ballsack back up from where it fell, and then putting your chinpo over that area. Also requires shaving and tape.
When done properly, it works well, but it hurts if you're not used to it.
Those gloves(and thighhighs?) bother me, like it's lace at first but it gradually fades in color before turning solid and then back to lace again?
How does that even work? It's not accidental either since it's the same on every page, such a bizarre thing.
