So asking my stepmom if she could give My new boyfriend and I a lift to the cinema should have been pretty straight forward. But when I went to find an atm leaving him alone in the car with her the last thing I expected when I got back was to catch him hitting on her and she sure wasn't fighting it. Anyway I've always been the forgiving type, and there was something a bit naughty about seeing them getting it on in the car so I was more than a bit horny. So as she drove on, I decided to show both of them that I wasn't about to get cut out of this party so I started sucking his big black dick while mum drove on. I knew she was watching, and I suspected she was touching herself down there as I took it deep in my throat..... Cinema was suddenly the last thing we were all thinking of!....this was heading only one way....check out both parts of this filthy story
