Reminds me of an experience in my youth in Vancouver. It was raining, I missed my bus. A horny guy offered me a ride. He saw me staring at the bulge at his crotch and exposed his cock. Then he pulled into an isolated parking lot where I sucked it. When he felt he would cum, he thrust my head down on his cock to ensure I swallowed his load so there was no risk of a mess in his car.
