I’ve (42M) been sleeping with my cousin (38F) for the last seven months.
Three years ago my wife and son passed away in an accident. My cousin who lived with her mom stayed with me for a few months to help me out.
During that time nothing explicit happened but we found ourselves snuggling while watching movies and one night we fell asleep on the couch together. We both sort of just laughed it off.
About eight months ago my maternal aunt passed away and I offered to help my cousin sale her mom’s house for her to stay with me for awhile.
We quickly fell into a home routine and found a lot of joy with each other. One night we had the right mix of edibles, wine, and Sci-Fi shows and ended up kissing and making out like teenagers and slept in the same bed that night.
The next day we said we shouldn’t peruse this and just leave it alone. We had sex that night and almost every night since then.
I have a vasectomy and neither of us have a desire at our ages to have babies and the only family alive other than us is her father who hasn’t been involved with her life since she was a teen. We are looking at actually moving and getting married; we do wonder if this ‘secret’ will be an issue in the long run.
Edit: to answer a few questions we are first cousins — our moms we’re sisters Legality — speaking with two lawyers our state wouldn’t allow marriage; however since we are not direct ancestors or descendants of each other and well past the age of consent the sex is not illegal (laws are weird)
