Institution X presents a raw, intense prostate stimulation session, where a sissy sub, bound and chaste, is edged to the brink of madness. His mistress teases his ass with strap-on, simultaneously massaging his prostate, drawing out moans of ecstasy and agony. The room fills with the scent of sweat and lube as she pegs him, pushing him closer to release. Finally, she milks his prostate, coaxing out a thick, messy cumshot, leaving him spent and satisfied.
