The teen comedy Morgan Stewart's Coming Home (1987) stars Jon Cryer as a rich kid who comes back from boarding school with a quirky new girlfriend (Viveka Davis) in tow. But when his stuck-up snob of a mother (Vanessa Redgrave) catches them showering together in their underwear the pair runs off on a moped. There’s no nudity here, but Viveka in soaking-wet undies may have you coming in your pants.
