Then came the embarrassing part, of course. Kay believed very strongly in the need to humiliate Lori-Anne, because she knew that her brother Big Joe liked to see his bride blush as much as Kay did. When the saleslady peeked in, Kay put her arm around Lori-Anne's shoulders, and turned her to face the woman.
Lori-Anne covered her bosom with her right arm and her privates, where she had squeezed out of sight the ungainly, useless parts that belonged to the self Big Joe would soon take her away from, with her left hand. She hoped desperately that despite the awkward bent-kneed posture she must hold in order to make herself look feminine the saleslady, an elegant dark-haired girl in her late 20s, wouldn't think anything might be amiss.
But Kay--as Lori-Anne should have anticipated--had other plans. "Can you go get us some white lace lingerie, sweetie?" she said to the saleslady. "As you can see--" (here she gestured at the lower half of poor, blushing Lori-Anne's body) "--the panties should be pretty big."
