i imagine when dabi's balls being droopy means that they sway a lot with every step, probably if he jumps they'd fall and slap his thigh, it probably stings, but also feels nice knowing him he'd like that sting, probably get hard too from juts the sensation of his balls swaying around and slapping against him he'd not only be hard but it'd be stimulating enough he'd be leaking precum the whole time i think he'd in turn be into ball slapping or face fuckign with balls slapping the face. or clit if its doggy.
