I fantasise that I am knelt behind you, @Shalatease. I pull your panties halfway down your thighs. My #cock is rock hard, foreskin pulled back, and my bellend is engorged. I hold both of your arse cheeks, gripping them tightly, as I pull them apart, exposing your beautiful tight arsehole. I position my head against it, and apply gentle but firm pressure. It feels so good as your arsehole starts to give way, and dilates around my cock, allowing me inside.
