Suggest doing something to make yourself look prettier

You trail one hand down to her crotch and rub her stiffening member. "Maybe you have some stuff in your closet that'll make my ass really look inviting," you suggest.

Marina's eyes light up. "Maybe I do," she grins.

When you get to her apartment, she leads you to her bedroom, then directs you to her accessories. You gather a few things and go to the bathroom. When you come back, you're wearing a g-string, stockings, and high heels, and nothing else. Marina watches with hungry eyes as you turn around and bend over, wiggling your pert butt at her. "Fuck, I want you so bad," she moans.
