We started when having sex talking about our fantasies. Me calling him a different name and how he is fucking my husbands pussy and hubby telling me the same. Cheating made up stories. A different name and how much better she is than I am etc. then his buddy stayed over and I secretly watched him jerk off. Told hubby about it. Then we started looking for couples online. Went to fantasy fest and I jerked off a few stranger cocks on my boobs and it went from there
