Blonde with big tits gets sweaty and wild with big dick in reverse cowgirl pose

I had had a bit too much fun at the pub the night before and was still hungover when it was time to go pick up Barbie Sins for her lesson. I was really feeling rough from last night's party as I made my way to pick up Barbie, but because of the recent social media links and whatnot I didn't want to get into trouble by cancelling. I'm sure smelling like a bar wouldn't be considered professional. I called up my mate Max, the big bloke owed me one. Maybe he wasn't an instructor, but one look at Barbie's huge tits and I was sure he wouldn't mind. Barbie was down, apparently, so Max offered to cheer her right up. It's good to have friends you can depend on!
