One day, I was attending a social event from work. Surprisingly, I met an old friend back in my college years. He studied in a different class, but I used to have sex with him and his friend a lot back then before I start dating with my husband! We reminiscence about old time how he and his friend often called me to their room for beer before they trained on me! It seems we both married now, but it would hurt for him to stop by my apartment...
