Mascarado 173, the master of kink, invites you to witness his urethral dilator challenge. With a gloved hand and a determined expression, he inserts the first dilator, his body tensing as it stretches his urethra. The camera zooms in, capturing every moment as he works through increasingly larger sizes, his breath ragged, sweat beading on his skin. It's a raw, intimate exploration of CBT that will leave you breathless.
