Polyamory leads completing the set

[MisterWolf26]

I've been sleeping with a cute grandma with a "done with it sexually" partner at home. Its all on the up and up. Everybody knows what's up.

Unknowingly I meet and get seduced by my favorite girls granddaughter. I start telling grandma (she hates when I call her that) about my new younger lover. She's a little jealous, but shes like family, and placated by some reassuring sexcapades, so eventually she wants to meet the new girl.

We all meet for karaoke night at the bar, and MOM shows up. Grandma and Granddaughter are suddenly in the closet, not wanting to own up to mom what they've been up to with me.

I get a little drunk and a little annoyed, and is Mom flirting with me?

A title pops into my head. 'Going for Three '.
A basketball reference but also hints at going for three generations.

And I love the story idea.
