His balls are pulled so tight

Dire Callahan and Derek Pain stand bound in restraints, their movements restricted by tight straps while Dire adjusts the harness on Derek’s hips. Derek’s asshole is stretched open by a thick plug, held in place as Dire secures the final straps around his waist. The bondage restricts Derek’s ability to move, forcing him to remain still while Dire ensures the harness fits snugly before pulling his balls taut against his body.
