I Have To Decide

When I first sucked his cock, I told myself it wouldn't, can't happen again.
Two days later as I was sucking gently on his balls before blowing him to completion, I reminded myself it was our last time together.
We met at the end of the week at a car park. He'd brought condoms and and I took my first ever anal pounding after he'd fucked me to several orgssms.
I got home sore and determined not to see him again.
His message that night read "You're so fucking horny. I can't wait to see you again".
My husband and I were busy that weekend, yet I still found time to go to the 'shops'. We had a quickie in the back of his car at the far endcof the supermarket car park. And again he took me anally (No condoms).
This has now been going on for eight months and I simply cannot resist him or his gorgeous cock.
He's older than me by twenty two years, yet I find him incredibly attractive and so sexually dominant.
He wants me to leave my husband and move in with him. So now I have a decision to make.
Stay in a near sexless marriage, or leave and enjoy a man old enough to be my father.
