Change the cream

The woman you had in mind isn’t there. Some teenage guy with a nose ring is staffing the counter, making a 'coffee' for a chubby woman in her 30s.

You mentally put 'coffee ' in quotes, because it's really a milkshake, it's got so much cream and sugar in it. You wonder how many of those things the woman drinks in a week.

It's too bad all those extra calories couldn't be directed to her tits and ass.

Wait a minute. Why couldn't they be? You grin and wink, not at the woman, but at the whipped cream dispenser.

Instantly, the woman at the counter is transformed. She weighs the same but the distribution of that weight is dramatically different and her clothing choices have changed to show that off.

She winks at you when she notices you noticing. You didn’t just make the whip cream cause bodyfat distribution changes; you made it an aphrodisiac as well.

She invites you to join her once you get your coffee and goes to sit down, greedily sucking down her 'coffee'.

You order yours black and while the kid gets it, you look to see the shop is much more crowded now. Every woman in the place is a brick house, enjoying their drinks with lascivious abandon. Your improved whipped cream is VERY popular.
