SOTB-010 - My girlfriend is an exhibitionist who loves to show off! She gets so horny outdoors that I had to let my friend take her...

My girlfriend seemed like a serious liberal arts student, but she was actually a pervert with exhibitionist tendencies. Worried about our future, I asked my friend to sleep with her. However, seeing her go crazy while being pounded by my friend's huge cock made me incredibly excited. Not knowing that I had set up this cuckold scenario, she begged me for more sex while crying and apologizing. We made up and had wild outdoor sex, becoming even more codependent on each other.
