When I first started raising this issue it seemed the only time fingers were being used was for anal penetration, but just this past week when I renewed my first time rooming was a FFF (yeah, I know
)and we did the daisy chain at one point, and I was DELIGHTED to see that had fingering as an action option for the three of us as we played.
That said I would REALLY love a pose that focuses on fingering. I don't think there's anyone who's ever had sex with a woman (regardless of their own gender) who has NOT put their fingers to use.
I don't want to detail the pose TOO much because I know I don't know your specs or plans, but I do want to give you plenty to work with.
-It could be one partner pleasing the other or it could be mutual.
-They can be Standing, Sitting, Kneeling, or Laying as far as the how's you can look to the MF hand job poses for inspiration (if not coding).
-There should be variation between penetration and rubbing the lips and clit.
-There should be speed/depth variations.
-Some kissing of the clit, thighs or stomach are all good possibilities.
-Depending on how the ladies are standing breast play would be an option. As would kissing.
However you would like to implement it, I would personally call it an essential development as a cornerstone of girlsex.
Chime in ladies, agree, disagree, add your own refinements, let's give them ideas.
