Separate, intoxicate, and humiliate

"Go team Bitch Wrath!" the bridesmaids said and fanned out. Tammy borrowed the facility keys from the janitor and locked the women's restroom. Gina pulled Robyn away from the the best man's bulge and chatted up her up as a distraction. While Gina was distracting Robyn, Yvette slipped a little magic powder in Robyn's drink.

Robyn took a couple sips of her spiked drink, which was Gina's cue to bump into her with her glass of red wine and spill all of it on her very tight top and skirt.

"Eek!" Robyn yelped and turned to run for the restroom to wash off the wine stain.

She immediately tripped on Tammy's extended foot. Her top popped up, exposing her ample breasts. She was right in front of the restroom door, so she left her breasts exposed to the wedding reception and to the eyes of the randy groomsmen as she pulled and pushed on the door and discovered it was locked.
