Door dashing

So I've been a dasher for 2 weeks now. When I first started I didn't quite understand how it worked. I thought I was supposed to knock on the customers door. I had a delivery at night. I went to the house and knocked on the door. This older man answered the door. He was in his late 60' or early 70's. He was wearing a see thru bathrobe. I could see that he was still soft but his cock still looked big. He told me his wife had died like 4 years earlier and he hasn't had sex since then. As we talked for a bit I noticed a huge bulge building in his robe. It got so hard it stuck out of his robe. OMG the size of it was amazing. It was like 10 or 11 inch's. Before long he bent me over his couch, pulled my pants down, ate my ass and licked my balls then he shoved his monster meat balls deep in my ass. He fucked me fast and hard for like 15 minutes till he came in me. He told me he really needed that and and thanked me. He did give me a $100.00 tip. It was fun
