The Mother-Daughter Threesome

I encountered a milf at a bar last night. Although she is 57 years old, she is still very charming and sexy.

We were drinking, chatting, laughing, and having a good time.

Then, she asked me flirtatiously,

"Have you ever tried a mother-daughter threesome before?"

I said, "Nope, not yet."

She drank a little more, and said, "Well, darling, tonight is your lucky night."

So she took me to her place.

She took out her keys, opens her door, turns on the light, and she yells towards upstairs,

"Mom, are you still awake?"

Explanation

Experiment

The joke plays on the listener's expectations. The milf's suggestive question and invitation lead the listener to believe a sexual encounter is imminent. However, the punchline reveals that she lives with her own mother, subverting the initial expectation and creating humor through surprise and misdirection.
