I fingered wife's workmate's arse
Sharing a taxi - three of us - me on one side, wife in middle and this girl Kate on the other side -
All of us drunk and it was v dark - I had my arm around/behind wife and I put my hand on Kate's should and as we went over a bump i slid down behind her back
She had lowish cut trousers on, v loose - shes also v skinny
Wife was leaning forward by this point so i had more space - she had no idea
I put my hand in Kate's undies, felt her crack a bit - she said nothing so i slid down further and could feel her ar se and i pushed forward , she pushed back a bit and she was sitting on my hand
I could now feel her lips from underneath - all warm - she wriggled about a bit on my hand and i pushed in my finger into her bum-
We did this all the way back to hers - she then got out and we went home.
I was hard as a rock at this point - wife thought it was for her!
Seen kate at wife's work events - she has never mentioned that night sadly..
You should have let wife suck or jack you off while you sniffed your finger and the scent of her ass on it!!!
