Young man meets hot cougar!

A shy young man suffering from depression and anxiety is seduced by his psychologist, a hot woman in her mid-40's.

Continuing with the description...
The woman had a predatory sexuality and a pretty interesting past: when she was at university, back in the mid-1990s, she performed in some independent porn shorts (shot in film and b/w). She stopped doing that when she met her future husband and got pregnant with their only child. Now, she was divorced and her son was attending college in another state. So, the young patient that she was treating was her perfect prey: innocent, fragile, good-looking and inexperienced.

What do you think could happen next? I'd like to see your suggestions!
Thank you!
