All the girls (can be in the Cyn and Jane era or the Yoko & Linda era) including Pattie, Mo, (could be Olivia & May too if you want to go even later, though logistics are complicated) and even side-flings you want have a giant orgy in the studio. Maybe they're sick of the boys and their "no-girls-allowed" clubhouse so they lock them in the control booth or the closet or something and have messy loud sex all over their instruments. Maybe it's while the boys are on tour and they start off thinking they're coming to comfort each other because they're lonely and horny and things escalate. Maybe it has nothing to do with the boys at all.
IDRC what the scenario is as long as there's hot wlw group sex and female empowerment involved.
Paul McCartney is THE most "pretty-pretty-princess" coded man of all time.
Like, look me in the eyes and tell me this isn't the prettiest woman you've ever seen in your life.
