Mom wants to be accurate

Your mom says, "Let's get the most accurate measurement." Then she lifts her dress over her head, revealing her lovely breasts -- big and bouncy with hard nipples. She's also wearing a pair of white lace panties.

"Mmm, you like getting lingerie, don't you?" the clerk says with a purr. Then she spins your mom to face you, while she is behind. Over your mom's shoulder, you see the clerk wink at you. Then she takes the tape measure around your mom's body, pulling it under her wonderful boobs. "35 inches," she says, checking the tape. Then she reached again, this time cupping your mom's breasts, feeling their weight. "Mmmm."

"Oh, that feels good, my dear," your mom says, obviously enjoying the attention to her boobs. Then the sexy clerk stretches the tape across Mom's tits and checks the length.

"39 inches. That makes you a 35D. What were you before?"

"I was a 35B," she says, leaving it at that, since telling the clerk she was a B-cup this morning would just raise questions.

"Oh, lucky to have gotten nice and big." The sales lady's hands return to your mom's boobs.

Your wishing must be working over time, because the clerk comes around in front and unbuttons her silk blouse.

"It's only fair that you get to see mine too," the sales clerk says with a grin at you. She opens her blouse and takes it off. The lacy pushup bra makes her tits spill out the top. Your mother moves behind her to unsnap the clasp.

"I want to see them too," she says. Once the bra is gone, you see that she has a nice pair of C-cups or so that the pushup bra made look like Ds. Your mother reaches around and starts fondling them.

"Mmmm, that's wonderful," the clerk says, "but I think we might be teasing your boyfriend here."

Your mother looks at you and grins, biting her lower lip. "Oh, we wouldn't want to do that too much, would we?" She doesn't mention that you are her son. "Maybe he'd like to come up and give them a try." Her eyes melt you with their heat. She takes her hands off the clerk's breasts and cups her own, almost juggling them before you. The sexy girl does the same.
