Pretty young brunette fucks stranger from behind in public

I was walking along the streets just as it got dark, people were going out for dinner, some out to bars. I was just taking a stroll when I saw this hot babe wearing a tight, spotted navy dress. I stopped her and told her I ran a modelling agency and I thought she'd be perfect to do some work for us. She'd clearly thought about this before. Although she was in a job that was getting her good money, she was intrigued by my offer. However, I said I would need to do a casting, just to make sure it was in fact a hot body underneath that dress! Strictly professional of course. Anyway, we found this stairwell that was private enough, it was in a multi story car park. She quickly got her clothes off after I handed her over the money, she had a perfect ass! I asked her if she'd be up for a bit of fun, just some fast sex for a big wad of cash. She agreed, got on her knees, licked up my cock and started sucking away! I got her up, pulled down her panties and slipped my cock in her pussy from behind! She was loving it! We had a couple of close calls of people being nearby but I had enough time to fuck her in a couple of positions before cumming all over her ass!
