Done this lots of times. In fact, most of the time I'm hooded and the dude comes in my open apartment door. I guess I have a way of filtering out trouble as there's never been any (except for one total jerk who was quickly shown the door). One dude came for a blowjob and in a quick turn of events, he had his fist up my hole twice for a total of maybe 30 seconds. I'd never been fisted and I don't know how he did it so quickly and easily. And I don't even know who he was and never even saw his face. I've tried to lure him back but now I can't remember which profile was his.
