I went on a hot spring trip with my best friend on a double date, but I ended up having sex with my best friend's boyfriend. My best friend's boyfriend isn't my type, but his physical chemistry was perfect. Honestly, I've always been jealous of my frustrated and lovey-dovey best friend. Even though I thought it was no good, I was so excited to do something naughty behind my best friend and boyfriend's back that I couldn't stop. Hey, this is a secret, right?
