Pristine Edge and her stepdaughter, Bianca Bangs, welcome a woman, Laney Grey, into their home. It's revealed that Laney is a tailor tasked with making matching baton-twirling outfits for Pristine and Bianca, because they'll be performing at a community fair for charity.
Laney requests that Pristine and Bianca strip down to their bra and panties, so she can measure them - she'll get more accurate measurements without their clothes in the way, plus it'll allow her to better envision the outfits she's going to make for them.
Pristine and Bianca are a little flustered but strip down to their bra and panties, standing side-by-side. Pristine and Bianca become unexpectedly aroused by each other as they are measured by Laney, and Laney also seems to be unexpectedly aroused. Eventually, Laney stops measuring them and comes onto them instead. Pristine and Bianca are surprised but receptive, leading to a steamy threesome!
