A bikini that's WAY too small

As you look over all the women's bikinis and imagine how sexy Melanie would look wearing them, you see something out of the corner of your eye: the children's section. Thinking about Melanie's ample bosom and large ass shoved into a bikini much too small for her makes you instantly forget about all the others you were considering.

Perusing the swimsuits, one in particular grabs your attention: it's a gold-colored bikini with a scale pattern, clearly designed for someone over a decade younger (and many sizes smaller) than Melanie. You grab it, along with some more clothes from nearby. Once you're loaded down with undersized garments, wave to Melanie and meet her near the checkout counter.

"Don't you think I should try some of that on first?" Melanie asks, looking at the pile of clothing.

"Nah, these are all the right size. Don't worry," you reassure her.

Once the cashier rings you up and reads off the (somewhat overpriced) total, you shake your head at him. "I already gave you the money, remember?" He gives you the items without question, and you realize it's the first time you've used your power for something non-sexual... Well, not directly sexual, anyway.

"Thanks again, Sweetheart," Melanie says as she helps you carry your purchases back to the car. "So thoughtful!"

Greg takes you all to a secluded beach that he knows about. It's a small sandy area, totally deserted and shaded on both sides by large trees... The perfect place for some private family fun.

You and Greg unload the car while Melanie gets changed. When she comes out, she's clearly uncomfortable: the bikini bottom barely covers her pussy, and if it wasn't for the extra-adjustable waistband would never have been able to fit into it at all. The side has completely disappeared between her cheeks, putting her fat booty on display. The top is no better, covering her nipples and not much else. It's stretched almost to bursting, too, and you see the outline of her nipples pressing through the material.

Greg's face reacts with shock, while the crotch of his swimsuit shows quite a different reaction. Obviously, your own trunks are getting pretty tight as well.

"Uuuh, Hon, are you sure that's your size?"

"What are you talking about?" You pat him on the shoulder. "It's a perfect fit!"

Greg immediately calms down, accepting the situation just like his wife... But he's still shuffling awkwardly due to his hard-on, and Melanie is doing the same so that the bikini doesn't burst. You watch for a while as they settle in... Greg clearly wants to fuck her, and you couldn't agree more.
