Lexi looked very sophisticated when I pulled up in the cab. She had a sexy office girl look which got my engine running. When she mentioned she loved horse riding, I couldn't help picturing her sliding up and down the saddle, it got me horny as hell.But I needed a way in. So when she made me pull in for a desperate pee alongside the cab, I saw my chance and captured it on my phone. Then good old blackmail was my answer.
