"Get dressed, then go down to the sex store and buy the biggest, thickest dildo you can find and bring it back here. And don't make any attempt to hide it, if anyone sees you."
Inwardly, Jennifer was appalled. But her sole sign of protest was a massive red blush in her cheeks, as she redressed herself, got her purse, and headed out for the sex store a few blocks away. She'd been there once, as a joke with her friends, looking at the huge dildos and laughing, wondering who would use them. Looking at them now, she was thinking something quite different, inwardly panicking as her eyes scanned the rows of sex toys, looking for the biggest one.
There, the black one. It was bigger than her arm even, a foot and a half long and three inches thick, in shiny black plastic and realistically sculpted with veins even. She grabbed one, and headed for the front desk to pay for it. The cashier, a lesbian-looking younger woman, winked at her as she signed her credit card receipt. "Have fun," she said.
"I will," she said involuntarily, secretly thinking, god no, please don't make me do this.
