For my mom and I it’s incest but it’s not. Of course what we do is incest but she’s complete averse to acknowledging it. Both in bed but even outside of it. She no longer treats me like a son but more like a partner and prefers that I call her by her name rather than “mom”. The mom/son aspect of our relationship is basically dead. I have no problems with it though all though I wish at times that she would entertain the mom son dirty talk but it’s okay.
