Overnights are certainly not for everyone and given what you have shared here, I can see why they hold no appeal for you. For others it's a dream and I have some subs that exclusively do overnights.

Regarding doubles, I am very picky about who I will double with these days. I remember being in a multiple Domme session (it was not My sub, I was invited) and the Dommes spent more time talking to each other than paying attention to the sub. Very unprofessional in My opinion. All I could think was, "this poor guy is paying to be subjected to this inane chatter".

These days I only sessions with Dommes I know take their craft seriously, that I personally like and that I have chemistry with. I am very fortunate that we have a close knit group of Ladies at Atlanta Dungeon, so scheduling doubles is not an issue. Mistress Ultra Violet and Goddess Samantha are among My very favorites.
