It's insinuated that a woman is pleasuring men from under a table, although nothing is shown the men have looks of surprise on their faces.
There are several suggestive scenes, and a lot of innuendo throughout the film. Kenneth Williams' buttocks are seen. Suzanne Danielle's breasts are seen briefly; she is seen lying naked on a tanning bed for an extended period of time, and her buttocks are visible. She gets up to have a shower and her buttocks are clearly seen.
