Sounds like you have a plan.
Get them.both together for a party, see how much of prude she is by approaching it in a fun way and see the reaction.
In that case, don't do anything and keep your pecker shut away. With those blue balls you have.
No matter what you do, that may happen anyway. She could blackmail you if she says no, or you could blackmail her to keep.fuvking if she let's it happen
Do it then..
Well hello there!!
Maybe your daughter!
I would love to slide into you, again and again!!!
She's a keeper!!
I would just fantasies about you and peek a look, try to see down your top and up your short skirt.
Yes, yes she is!
Wow, fucking fantastic!!
Very nice, need exposing more!!
