Plot

A teenage boy named Eric already has a gorgeous sweet-natured brunette girlfriend of his own age-group, yet he develops a lustful crush on a considerably-older flaxen-haired women named Helene when he sees her and her male lover Francois playing tag on the beach and then having wild intercourse on the dune-grass. An intimacy soon develops between Eric and the comely matron; as Helene sobbingly explains to Eric, she is feeling extremely lonely and "sexually neglected" due to her live-in lover Francois's being away for a few days, and so the teenage boy is perfect company in her time of need. During their time together, the boy naively assumes that the lady has genuinely resigned her heart to him; however, when Francois returns and Eric catches them making love once more, he realizes to his shock that she had merely been using him as a "boy toy" for temporary comfort. Now heartbroken, Eric must make sense of his feelings; he soon realizes that his relationship with his own similar-aged girlfriend is far more suitable and satisfying for him, anyway.—lament

Despite his already having a similar-age girlfriend with a shapely buxom figure, long dark hair, a sweet freckled face, huge gentle brown eyes, and a tearfully-submissive nature, a teenage boy develops a lustful crush on a considerably older flaxen-haired lady when he observes her male lover playing "catch the girl" on the beach and then engaging in playfully-aggressive intercourse with her. The next day, the boy's cravings are further aroused when he observes the blonde woman sunbathing nude on the beach, and then later, while in the company of his own girlfriend, he spots the woman heading through town on her bicycle. On a desire-driven impulse, the boy mindlessly rushes off from the outdoor diner-table where he'd been conversing with his own lovely mate, and discretely follows after the comely mature dame on his own bike that is fitted with a motor. Using the wily ruse of letting the air out of the woman's bike-tire while she has momentarily stepped inside a shop, the boy then watches from a distance till the woman reappears and discovers her flat, whereupon the boy putters up beside her and pretends to have "just happened by on his bike and observed her distress" as a way of striking up a conversation with her. He gives the lady a lift home on the back of his motorbike, and she agrees to hang out at the beach with him the next morning. They spend much of the following day together relaxing on the sand, and then later that evening, unable to sleep with his wildly raging hormones and lustful fantasizing about his new friend, the boy returns to her house and observes her sitting near the window and sobbing dolefully. Sensing an opportunity, the boy goes in and learns that she is feeling lonesome and neglected by the absence of her lover who's away in the city. In the process of comforting and sympathizing with the tearful damsel, the boy gradually develops an intimacy with her. Interspersed with their passionate lovemaking is footage of the brothel where the woman's philandering lover has gone, showing him in various stages of "servicing" the tastelessly-costumed females from the establishment, while being observed by other equally-hideously-outfitted attendees. In an unexpected ironic twist to the plot, the boy's young brown-haired lover is shown to also be present at the same brothel; she, too, is feeling romantically ignored in the boy's absence, and so she has travelled to the brothel in search of "substitute" sexual solace; she is role-playing a crying infant in a crib who is then "pacified" by a male client who allows her to "suckle" by giving him oral sex. The teenage boy's torrid affair with the woman plays out over the course of a couple days, during which time the boy naively becomes convinced that the woman has resigned her heart to him. When the woman's male lover eventually returns to the house, however, the boy observes them making love once again, and realizes to his extreme shock and agonized feelings of betrayal that the woman had never actually had much in the way of true romantic feelings for him, but had merely viewed him as a "boy toy" to temporarily slake her misery-racked cravings for intimate male companionship during her lover's absence. So in a devastated fit of heartbreak, the boy recklessly rushes back to the seacoast with the intention of committing suicide by flinging himself off a high bluff onto the jagged wave-pummeled boulders below. Fortunately, his lovely brunette sweetheart has returned from her own "adventure abroad", and she meets back up with the boy before he nerves himself enough to actually jump. Nestled in her close gentle warm embrace, and listening to her soft soothing adoring voice, the boy recognizes how precious life truly is, and realizes that his own cute teenage girlfriend is much better suited to him than a much-older lady, anyway. The film ends with the happy couple engaging in close loving intercourse on the sunny windswept hillside where they were reunited.
