A proper stretching indeed! The dominant, clad in black leather, begins with a gloved finger, then two, three, working the submissive's asshole open. The submissive, bound and helpless, begs for more, and the dominant obliges, pushing his entire fist into the tight hole. The room fills with the sounds of wet, sucking flesh as the fist slides in and out, the submissive's moans growing louder with each thrust.
