My ex and her friend had an interesting relationship. They were both insecure about with their bodies and both had a sexual history together. When this took place, they were both 18 and I was 24. They were recently out of High School and still experimenting.
At this point, my gf and I were co-workers and her friend lived out of town. We were both helping close while she took time to reply to her friend, who had been texting her all night. As we finished up and were about to leave, she stopped me.
