And he’s approached by a POW (Predatory Older Woman) who asks him if he’d like to go back to her place. After they are just getting comfortable in bed the woman asks the guy, “Would you be interested in a mother-daughter threesome”.
The guy is surprised but instantly agrees.
“Great,” says the woman and then calls out, “Mum he said yes!”
