Four sex-loving adult amateurs sign up for a 245-minute documentary featuring genuine condomless sex, repeated orgasms, follow-up pounding, and 27 real creampies. Ruka, 26, is a married dental receptionist awakened by a cuckold shoot arranged by her husband; she requests raw group sex. Kurumi, 20, is a shaved discount-store clerk obsessed with cum and takes consecutive creampies. Moka, 21, works at a vintage clothing shop and wants to be overwhelmed in a four-person orgy. Miki, 32, is a high-libido F-cup married woman curious about group sex, and she cums repeatedly while receiving eight creampies.
