Dip Undies

Found this brand carried at Kroger a month back.  Pretty soft.  Not necessarily atomic ready out of the package, but the legholes are really stretchy.  Stretchy enough to put my hands behind my back and use the left leghole to tie my right wrist, and the right leghole to tie my left wrist - the wedgie I gave myself while struggling to get out was fantastic.

Just sharing - bought them on a whim.

I personally love the Dip brand briefs myself. They're not as stretchy for atomics like you said, but they can stretch if you still want a quality wedgie in them. Though they don't have a lot of variety in colors (Classic tighty whiteys/black/gray). Definitely would recommend them

Yes, they're not the most attractive TWs to have on, but they do serve the purpose well
