Aliki and Alexis, a very sexually active couple, are spending their summer vacation in the magnificent island of Santorini. With the consent of his wife, Alexis, an artist (a painter), often has brief affairs with his naked female models. His new summer models include exotic girl Ajita (who only has sex with her black boyfriend Jimmy and a local stud, played by Nikos Kokkinos) and Monica, a sexy blonde who is visiting Santorini along with her friend Dimitris (a well-known “kamaki” of the Athenian Syntagma Square, i.e. a local playboy in the habit of trying to seduce foreign girls on vacation in Greece). Alexis is immediately attracted to Monica and has sex with her, whereas Aliki proves to be even more active, fucking with Dimitris, but also occasionally with local guys. Even if the jealousy starts to eat away at her, inciting her to try and keep Monica away from both guys (her husband and her lover!), the erotic heat between the two couples proves to be irresistible. The sexual couplings on the island are spiced up by the sporadic interventions of the local incurable Peeping-Tom, Mitsos, who usually ends up in the water! Mitsos blackmails Dimitris, insisting on recovering the money lent to him in the past, on the occasion of his previous sex visits on the island. Monica proposes to give Dimitris the initial sum, but Mitsos demands the interest as well, suggesting, however, that he is willing to get paid “in kind”, were Dimitris to convince Aliki to have sex with him. Aliki agrees to this deal and is eventually presented to Mitsos as some kind of birthday cake, covered up with whipped cream! Mitsos licks her all over, but is soon confined to his voyeuristic habits, as a big orgy takes place between the two couples in the presence of Ajita and her two lovers.
