What better 4some could there be in ORS?
Alison and Cindy couldn't handle long term polyamory. Cherry and Lena is a no-go (unless things drastically change). Ivy shows no sign of being capable of any kind of sustained romantic relationship, though she could join in some times. Bad Jess is in kind of the same spot, though Good Jess and partner might swing, but probably not more than that. Louise's jealousy would sabotage anything beyond group sex, unless kept firmly leashed as a pet. Minerva has a whole adult life, too much to be dragged into anything serious unless she burns all the strings connecting her. Gillian is
the poison pill, to anything including Ian. And everyone else would be fun for a fling, but hasn't got the connection to the rest of the Holly Trinity. Emma is liked by all, can handle an alternative romance, and can teach everyone the Way of Anal Satisfaction.
My dream foursome is Lena, Ian, Cindy and Wade. But brother since I'm starving for swinger content, at this point I'd even take Emma and Perry as a substitute for Cindy and Wade lol. For MFFF foursome it's got to be Ian, Lena, Ivy and slutty Holly.
It'd be hot, but I don't see Cindy growing enough to put up with sharing the limelight more than once or twice.
But yeah, if we're doing straight group sex with a solo M to all the Fs, that's a good choice, but I think Emma could be a pillar and Ivy the visitor.
