Background: I'm a 28 year old lesbian who lives with my mom. It's cheaper for both of us since living alone where I am would be unaffordable and roommates are terrible. Plus we are genuinely close and I enjoy her company, so living together is nice. I am also a virgin who occasionally dates and has actively been trying to lose my virginity. My mum can be nosy and I do not enjoy lying to her. If I'm texting someone she asks who. If I'm going out she wants to know where, for how long, etc. If I'm on a date she wants to know what we did, when I'll be home, who it was with, how it was.

The issue: I went on a date recently with someone I met on feeld. We are now in the beginning stages of a domme/sub relationship and it will likely progress. It will not be a romantic relationship at all, purely sexual. My mom knows I went on the date and that it went well but obviously I did not give details. Now I am struggling with what to tell her as the situation continues. I can't keep saying I'm going on dates, because she will eventually ask why I'm going on so many dates with the same person but not officially dating them, do I want to be dating them, etc. I can say we decided to be just friends, but then I have no way to explain why I'm getting dressed up every time we hang out. I can't just say I'm going out and not tell her with who or to do what because she will keep pressing me until she gets an answer, and like I said, I can't really lie to her (long story there I'd rather not get into, just take my word for it). So how do I explain where I'm going and with who without telling her the truth, which is that I'll be going out and having really kinky sex? Also important to note, we are NOT a family that talks about sex. So I can't just tell her I'm going and getting my back blown out. Not only would it be awkward but more than likely she would be extremely judgemental about it and then every time I go out after that would be a whole thing.

Does anyone have any suggestions for how to handle this?? My current thought is to go with the "decided not to date" route and then say im getting dressed up because my new friend likes to get dressed up and it's fun to have a reason to do that (note: I don't normally wear makeup when going out with friends and rarely wear dresses, both things I will be doing when going out with this new person). But I feel like that's going to be super flimsy if she asks anything at all?? Help!!
