A clandestine, throbbing desire fuels this clandestine encounter. The gloryhole's partition trembles as a colossal cock pushes through, seeking untouched lips. The initiate's breath hitches, heart pounding in their ears. They lean in, tongue tentatively exploring the velvety, hard flesh. The cock jerks, leaking pre-cum, as the initiate tentatively sucks, their inexperience evident in their hesitant, eager motions. The room fills with the sounds of wet, hungry suction, the air thick with the scent of sex and sweat as the initiate races to master their new art.
