Takes place at HER place, never yours.
Get the female to strip naked without you so much as touching or kissing her.
She gets on her hands and knees, lowers her head to the ground (or bed).
Mount the female from behind. Oh, with your clothes on.
Condom is optional, if she makes you wear one, just before you come you pull out and slip it off (lube helps), then re-enter her for a few more strokes.
Pull out, quietly gob (spit) on her ass so she thinks you came.
Then she starts to turn around, jack off in her face, see pearl necklace
Put it away, zip up, and leave without looking at her or saying anything.
(If you did use a condom to the end, pull it off so it drips on her ass, and discard it on her carpet.)
I was the one whose turn it was to fall on the grenade
so I went home with the sealfuck
, did her donkey kick style, and left right after. I could hear her crying as the door closed behind me.
