Ok, so I mid/late forties. I was young when I saw it and in my mind, I had always thought it was a late 70s/early 80s BBC Play for Today called something like 'Looking for Linda' - but I can find no evidence of such a thing existing.
It was about a boy who comes to see his gf - can't remember if they are still dating or he is trying to win her back, but she isn't home. The mum is home, and I can't remember how it evolves but they have a sexual relationship.
I remember the boy had a black leather jacker and that's it. It was the most shocking thing I had seen at that age and for no reason at all, I am curious as to what it was.
Defo 'Play for Today' feel about it.
Any ideas
