Lf Mother of Gf who's a call girl

Starts off at an office where the milf says how her daughter is dating someone and she gets her libido from her or something.

Milf gets a message or something to go somewhere (so as a call girl im assuming.) Turns out it was the boyfriend of her daughter.

They have sex anyway, and if I'm remembering correctly, there was a scene where the daughter calls while theyre still having sex.
