Yah I'm not too worried about 1 staying unique, all the jumpoff points you mentioned are good for ffm stuff, the movienight, the derek/lisa dinner, or sandy stuff or coco. Hell, they could even involve the new boss-lady.
Separately, comparing the 2 reminds me that LWT 2 had a decidely "ntr slant" IMHO, which LWT1 never had, and I hope it stays that way. Even comparing the various MMF or swinger events in 1 and 2 - in 2 they all have this ntr aftertaste, like the girls banging the stablehands or the "friend" in office. In 2 it's like you're either a "big winner" or a "big loser" at the end, at least american sunset so far feels more chill, though they haven't ported the "endings" over.
