Solo Pasivo, the uploader, is back with another episode of intense, solo fisting. This time, he's set the scene in a clinical, sterile environment, starkly contrasting with the carnal act about to unfold. With a gloved hand, he applies generous amounts of lube, his other hand working his cock to a stiff erection. He spreads his ass cheeks wide, revealing his tight, pink hole. With a deep breath, he presses two fingers in, twisting and scissoring, stretching the muscle. He adds a third, then a fourth, his body convulsing as he pushes through the tight ring, his fist disappearing inside, knuckles first. The room echoes with his guttural moans as he fucks himself with his entire hand, his body writhing in a dance of pleasure and pain.
