I Can't Believe I Cheated. The Guilt!

I did it. I own it.
I have no idea why I did it, though, and I am paranoid hubby will find out.

We've been married 11 years and have 2 kids. Sex is fine and even with 2 kids it never dropped off really. He's a good provider and I only have to work if i want to which i don't. I thought I was happy and still think I am but I can't explain why I cheated a few days ago completely out of no place and really liked it.

I met Danny at my kids daycare. I don'tveven need daycare because I don't work but my husband tells me everyone needs breaks and its good for our youngest to be social. Danny and I drop our kids up at the same time and we chit chat in the morning but i never thought much about it. He's a good 10 years younger than me and even if we were the same age guys like him are out of my league. He is hot, buff, and just has that bad boy look. I enjoyed his polite "hellos" and "hows it going?" in the mornings but think nothing of it. Then out of nowhere he asked me if I was in a hurry or would I like to get coffee. My heart instantly went rapid on me and I felt my whole body react. There was a Starbucks in that plazza so we are sitting there drinking coffee and I am suddenly so nervious like I just know something is going to happen. We try making small talk but I am clearly nervious and he can tell and it gets awkward. So suddenly he has says, "My wife is out of town all week so nobody is home at my place do you wanna come over?"
We both knew what he meant. I was in shock and freaking out inside. But for some reason nodded yes. And before i knew it we were in his car and he was all over me coping feels up my shirt and deep kissing me. And I was on fire and would have car fucked right there and was reaching for his crotch to start just that. It was pure lust and I didn't care I was married. But this was clearly not his first time so he was like,"Not here another parent could see us my place is empty."

We fucked right in thier bedriom where they sleep together. I was getting pounded doggy and looked up and saw her clothes and make up all over her room. I had so much guilt but some how it made it hotter. He was ripped, fucking perfectly fit body, a decent dick, and he knew what is was doing. It was fast and hard and he was so strong and it he could keep the pace up like it was nothing. I cummed my fucking brains out all day long. When we were not fucking I was running my hands all over his perfect man bod and sucking him hard again. We litterally went at it until we had to go back to the daycare and pick the kids up.
When I went home that night i felt so guilty. I am a horrible wife. My husband does everything for me because he really loves me and this is how I repay him?

Its been two days since I've been back to the daycare because I know when I see him I'll want to let him fuck me again. And I know I have to eventually go back. I also know I feel like shit for doing it but if he asks me to again I will say yes without hesatation.
Does the guilt ever go away?
