At a meetup hosted by a perverted anal-loving circle, a curious girl named Maki-chan is restrained and blindfolded for play. Both her pussy and anus are extremely sensitive, and she undergoes torment using a spreader bar with vibrators inserted into both holes. Unable to withstand the intense stimulation, she orgasms repeatedly in a wildly depraved state. She particularly loves simultaneous dual stimulation, and even while sucking cock, she constantly craves anal stimulation. Additionally, the scene features enema play with large quantities of milk, making it a must-watch.
