Sleeping With A Married Man

So I don't usually do anything like this at all. But I was out with a friend a few weeks ago at the bar. We were sat alone when a guy came over and introduced himself asked how we were and if he could sit with us. He was very chatty and likable, he invited a few of his friends over to sit with us and we all got talking. A few drinks later, he admitted he had approached us to try and set me up with his brother. However there was just no chemistry at all. The issue was there was a spark between us, he straight away told me he was married and was not the type of person to cheat. But the chemistry was there we just clicked. We tried to fight the urge to take it further than just a playful flirt, but we just couldn't keep our hands off each other. It was so passionate, he looked me deep into my eyes and then started to kiss me softly, he slid his hands into my panties and fingered my wet pussy, I moaned with pleasure as I pulled him into me. I stripped off and started sucking his cock, it was so big and hard. He went down on me and licked me out until I came, by this point we had definitely taken it past no return, I wanted him inside me so bad, he lifted me up in the air making me feel so powerless and under his control, he slid his cock deep inside me and it felt amazing. We Fucked for what felt like hours and I came all over his cock. We've been meeting up alot since, we both feel terrible about it but can't seem to help ourselves there is just such a connection there it's like a strong lust. What do we do from here!?
