Betrayed my husband

My husband works in Prudhoe Bay Alaska. He is gone 4 weeks at a time. He is due home tomorrow. Last night a hunting buddy of his came by to pick up ice fishing stuff. I had already drank some wine and once we got out to our garage we started with kinda flirty banter. He found what he came for but before he left he pulled out a gram of ** and offered a line. It was wrong but we both did a line…and we ended up kissing. Because of the wine and ** we ended up having **.

We barely started and he stopped and hade me beg him to remove his condom. I am riddled with guilt. I acted so slutty/whorish.

Now my husband will be home in 4 hours and I have finger tip bruises on both hips and even though I showered, I still feel his fluids inside me. I am freaking out. I am sorry and I feel guilty.
