We were going home on the evening rush hour underground train from Leicester Square to Morden. It was hot, overcrowded with people pressed up tight barely able to move.
I was penned against a glass partition by the door with Nirmala, my wife facing me. The train was slow and kept stopping, the lights flickering sometimes going off completely.
Nirmala is 35 dressed in short black pleated skirt and white blouse.
The train lurched causing the people behind to squash us and for her to press tight against me.
My hands were around her well rounded backside, feeling the outline of her panties through the skirt, knowing she wanted fucking as soon as we got home.
There was a balding white man pressed up behind her, he obviously felt my hands on her buttocks. Nirmala whispered, "he's got a hard on and is pressing it up between the cheeks of my bum", she encouraged him by pushing back and wriggling her bottom.
I felt the crotch of her knickers, it was indeed damp and not from sweat. I eased the panties to one side and inserted my middle finger in her cunt and masturbated her. No one else could see what we were up to, she rested her head on my shoulder.
He sensed what we were doing and slid the skirt above her bottom, fondled and massaged her arse cheeks. He looked at me and since there weren't any objections, slid down the yellow satin panties below her buttocks allowing him access to caress her naked buttocks.
I felt his finger probing for her pussy opening, I withdrew allowing him to replace mine with three of his. Nirmala's breathing became short and erratic holding onto me for support.
The train was still travelling at snail pace, when Nirmala whispered he's got his thing out.
She could feel his bare hairy cock on her unprotected bottom. I felt her pussy again and was stunned to feel another man's penis searching for my wife's cunt.
