A man comes back home, looking for his wife, but she's not there. While walking in, he notices her daughter (which is not his daughter) sitting on the couch reading. So he decides to sit at her side. As soon as he does this she removes her shoes (we get to see that clearly) and put her feet (wearing blue nylon socks) on his lap. She starts moving them, trying to tease him (later on they will have an affair)...so he starts caressing her legs... and after a while his wife comes back home, so the girl runs away. The actress was 21 at the time of the film, even if she's playing the part of a 16 years old girl.
