My wife and I had been together for about 7 years at the start of all this, married for 4. Our life together was pretty good – we both had decent jobs, a nice house, and we enjoyed time spent with each other. We shared a gym membership and kept in shape, but neither of us had rock hard bodies. The sex we had 2-3 times a week was good, and though I was always up for more, I was happy with what I got. I was always kinkier than her, and often brought up new ideas – using a vibe, tying her down, etc. She went along with almost everything, but drew the line at threesomes. She didn’t like the idea of having sex with a stranger, and didn’t like any of our friends ‘in that way’. I eventually let it go, playing it out in my fantasies over the years.
She started grad school, taking classes after work a few nights a week. Her second year in she joined a study group, and soon after had a ‘Study Buddy’ she worked with. She described him as a nerdy kid, definitely not someone to be threatened by. The semester rolled on and she stayed out later and later with him. I didn’t doubt they were studying – her 4.0 GPA proved that much – and everything was good with us, so I didn’t have any reason to worry.
