I (28F) fucked my cousins husband on our family vacation.
My cousins 28F & 35F, and my older cousins husband 45M went on vacation together. Myself and my older cousin don't really get along, we never have.
it was my first time meeting her husband (and baby daddy) on that vacation because she had moved to and met him on the other side of the country only a few years prior.
Anyway, long story short my cousin was being a huge bitch to him the entire time and he ended up leaving their hotel room one night. He stayed with me and we ended up fucking for like 12 hours. We fucked the entire time but maintained that nothing happened.
This went on for years throughout their entire relationship really. They moved back closer to our family and so we only lived about 20 minutes from each other which made it really easy. They recently separated and now he wants to take our relationship public, but I'm kind of over it.
