To make a dress adjustment

As Mackenzie is distracted, Kaylyn walks up behind her best friend who is leaning over slightly, and notices the perfect situation for her plan. As the other 3 continue to chat, Kaylyn sneaks her hand to back of Mackenzie’s dress up by the back of her neck which isn’t firm against her neck, Kaylyn swiftly and secretly grabs the small zipper and slowly begins to bring it downward towards her shoulders.

Kaylyn has a mischievous smile on her face as the zipper reaches Mackenzie’s back, exposing the back strap of her shiny gold strapless bra, causing Kaylyn to stifle a laugh at her friend’s bra choice. She continues on, pausing for a moment as Mackenzie straightens up for a second before slouching back forward, allowing for Kaylyn’s continued unzippering of her dress.

The zipper continues down Mackenzie’s back at a slow speed, then it reaches her waist, where Kaylyn knows there very little zipper left. She gives it the slightest tug down to its lowest level, giving her sneak peek at her best friend’s panty selection, giving her the biggest smile of all as she lets the zipper go and sits down between Mackenzie and Joey.
