Metal rod penetrates cock's urethra, shaft rigid and veined under wife's firm handhold. Balls swell purplish, chained tight by thin ring — hairy skin stretches taut against metal bite. Fingers dig into soft scrotum flesh, pulling cheeks wide for deeper probe. She twists the sounding tool slow, base slick with precum ooze, while thumb presses ball weight downward. Bondage bites in, cock twitches helpless in her control. Dim light catches every ridge on the toy, every vein pulsing. Wife's nails scrape tender underside, drawing out strained breaths from the tiny captive dick.
