Threesome

I met an older woman at a club last night.

She was an all right sort for 57, we drank a bit, had a bit of a chat and she asked if I'd ever had the sportsman's double, a mother and daughter threesome?

I said no.

We drank a bit more, then she says that tonight was my lucky night.

I went back to her place.

She put the hall light on and shouted upstairs: "Hey Mom! You still awake?"
