Helpless guy tied to chair, legs roped wide, tight white briefs hugging his full bulge.
Avenger threatens to “pop them for good” while delivering hard punches and legkicks straight to the package.
Bulge flattens hit by hit—lumps cave in, contours disappear.
Final savage kick (with round compressible orb inside briefs for effect) drives through and everything flattens completely with a crunch. No recovery. Permanent damage.
