A documentary of a two-day, one-night hot spring training trip to awaken the dormant masochistic tendencies of the beautiful yet extremely lewd housewife, Rei Saegusa! First, they open up to each other with a flirty date at a roadside station, then they have intense, mind-blowing sex in the open-air bath, followed by rough, trembling anal sex! Remote-controlled vibrator training inside the hotel, and then limb restraint and blindfolded orgasms to the limit… The development gradually becomes more intense from a mellow atmosphere, and the masochism within Rei blossoms. Be sure to check out Rei's "true" eroticism, which she only shows when she's alone with a man, and the masochistic tendencies that gradually emerge!
