Nicola Pagett in sexy scene from There’s a Girl in My Soup which was released in 1970. There is not so much nudity but Nicola Pagett looks pretty hot in that underwear. Also Gabrielle Drake naked in There’s a Girl in My Soup. We can see sex scene with her. So Gabrielle Drake is not shy and she demonstrating her boobs.
If only Ms Drake had been offered more roles involving nudity, but there's just this and Au Pair Girls.
