An English Tale

[JackLuis]

Woman teacher 'caught in lay-by with sixth-form boy after ball’

I'm guessing that a 'lay-by' is a side road, or a side the side road.

It doesn't say what she was doing in the car, she could have been counseling him about his masturbation problem?

 

[Handley_Page]

A 'lay-by' is a widening of the road for a short distance to provide an area where a vehicle can stop and the regular traffic can continue.
For example, see here.

Don't forget we drive on the LEFT of the road.

And I have a thought that the little b* who sneaked is going to be in trouble; for being a sneak.
[sneak - a tell-tale, one of tittle tattle, spreader of rumour and tales. ]
