I run in to a guy on the side street

I start to head towards the main street and a guy bumps in to me , grabbing my ass. It catches me by surprise as he hears me softly quietly moan , remembering what I did earlier. This emboldens him he works a hand in my shorts finding my thong , working his hand around to quickly find my pussy slowly pushing two fingers in and out, this derails my train of thought, he pulls them out and walks towards an alleyway just around the corner. I bite my lip the feeling of him pulling out of my pussy sending shockwaves through me. I catch a look at him before he disappears around the corner , a decent bulge in the front of his pants and dark hair, quite tall.
