Waking up this morning, I felt so ashamed of myself. I even contemplated telling him everything, but I decided to put what happened down on this site instead.
Out with my husband Charlie two days ago, we had a huge argument in a restaurant as he'd told me he'd spent nearly all our savings (Four thousand pounds) on a few horse races. I stormed out and left him to pay the bill, then jumped into a taxi.
Realising about half way home, I'd not brought any money, I told the driver. He told me "As you're good looking you can pay me what you owe, in kind". Still very angry and having had half a bottle of wine, I thought to myself (Actually I wasn't thinking) ok then I will.
He pulled up along an old dirt road, near to a farm (We live in a rural area) He climbed in the back seat with me and over the next half an hour, I had anything goes sex with him. I sucked his cock, had him lick my pussy and arsehole, then as I knew I wasn't on the pill, I had the driver fuck me in my arse. It was an amazing fuck, one which had me cumming twice. When he told me he was going to cum, I told him cum deep inside my arsehole.
When he pulled out he got me to lick and suck his cock clean, something I'd never done with Charlie. Back at home I sat going over what I'd done, until Charlie showed up. Straight away he said "You never let me finish, the money I spent on the horses, I won with it". It turned out he'd been told of a sure bet by a race horse trainer. Putting the bet on, he won six thousand pounds.
I felt terrible. I'd cheated on my husband, and I really enjoyed the sex with a complete stranger.
So over the last couple of days I've thought about nothing else. And am now wondering if I should confess all to Charlie.
