A friend and I were vacationing in the LA area for a few days and elected to go out to a bar the night after New Year's, it being a Saturday. Most places were dead but we found one with live music. We are drinking, trying to chat up the various girls there. The details are a bit fuzzy, but at some point I offer my hand to dance to a older tall thin woman in a cute skirt (she later claimed (plausibly) to be 43). I remember her as an HB8. She accepts, we're dancing. At some point she encourages me to go talk to the younger girls there. More dancing. At some point, I must have asked her if she wanted to step outside. I recall being outside making out with her.

I ask if she's ready to get out of here. We walk to her minivan (I cannot make this up). We're driving a bit when she's asking about my friend, who I guess she last noticed with my friend. I call him up and they're waiting in front of the bar. We drive back, pick them up. I recall her friend being maybe a HB7-7.5 She drives us to the place we're crashing at, belonging to a buddy of my friend. My friend disappears to the room he's crashing in and I have HB8 there on the couch in the living room twice. She apparently has kids and I could swear I noticed a wedding ring. All sorts of Mrs. Robinson references jump into my head.

I will say this for older women: there is no obstacle course of LMR and they will let you know what they want. She asked for the condom before we started anything serious.

Her friend comes out of the room with my friend. He gives her a slap on the ass and the two are out the door, back into the minivan they arrived in.

Followup: I later learned that they had been eyeing two guys even younger than us, who seemed initially interested, but my friend read them as being unable to follow through with it. These women were filtering for the sure thing that night and we were it.

TL;DR: A friend and I are successfully hunted by cougars. Sometimes just being there and being ready is all it takes.
