Double Penetration In Bathroom

I needed to pee. I walked to my local toilets, you never know, there might be a cock I can suck today.
The man standing at the long silver urinal when I entered was in his 40’s, white, rugged, not handsome but very manly, thick shoulders, square head and the way he looked at me he was clearly assessing me.
I stood to take a leak and he stayed there, waiting it seemed because he wasn’t peeing at all. I figured I might be in luck here.
I finished and shook the drips off, popped it back into my boxers and zipped up. I looked across and looked back to see if I could see his cock and let him know I was interested.
As I was about to take a step back, he appeared by my side, grabbed my shoulders and pulled me back. He turned me around and pushed me into the cubicle/stall. He came in standing between me and the door. He grabbed my left arm in his right hand and locked the bolt on the door with his left.
He turned and he moved his right hand down to my groin. He held my entire package in his hand, not difficult given my soft size is just a couple of inches, if that.
I wasn’t resisting much and looked up at him with a hint of anger and a hint of excitement, this certainly had the promise of being out of the ordinary. He was over 6ft and I’m just 5’6″ so that only added to his domination. Then he surprised me again.
As he felt me through my jeans, I was moving to feel him when he put his hand under my chin. He held me by the throat and moved me to my right so my back was to the cubicle...
