If you ever had the temptation to cheat, just know that it is not worth it. If you get caught, you have the potential to lose everything. If the person you are cheating on your partner with does not know you are in a relationship, it can end badly if you get caught. People like that tend to lose both partners.
It was such as case in this situation, where the guys found that they were both being swindled by the tattooed girl. They ended up collaborating to get back at their former partner.
