A prim and proper company president's wife is depicted indulging in lewd molestation acts with her lover right inside a train. Though she appears to be a typical victim of groping—dedicated to her serious job—she's actually enjoying the affair. Boldly going commando and ready for action on the train, her daring behavior symbolizes the evolving nature of modern infidelity. The scene then rushes into a hotel, revealing the intensity of her desires. Should anything go wrong, she shamelessly pretends to be the victim to avoid getting caught. It's not her rigid career that's tearing her apart—it's her lover's stiff cock.
