Positioned on my gynaecological chair, my slave serves as the perfect toy for an extreme, deep fisting session. Step by step, I work my way deep inside of him, using my full body weight to sink one fist in, before the second one follows. Having both of my hands deep inside of him fills him completely and stretches him to his absolute limits. After a quick break to reapply lube, I push right back in, building intense pressure and working his insides with precision. The intense inner friction eventually sends his pleasure over the edge. During the double fist punching, he reaches a hands-free orgasm without any touch to his caged dick, spurting his load right through the bars of his chastity device.
