Having sex with my friend's spouse

I'm a guy who always wanted to have sex with my best friend's wife. I finally got the chance when he was out of town for work. I went over to his house and she let me in. We went upstairs to the bedroom and I could see she was wearing nothing but a bra and panties. I couldn't believe it when she started taking off my clothes and then she took off her own. We started kissing and touching each other. I could feel her wetness through her panties. She took them off and then she took mine off too. We were both naked now and she was riding me hard. I could feel how much she wanted it. We kept going until we both came. It was the best sex I ever had.
