Tell her about the rest of the outfit.

"Well," you start, keeping your hands on her torso, gliding them over the soft ridges of muscle and skin, "get your loosest shorts, and leave your panties here," you breathe. Jess moans and shakes her head.

"I'll be falling out of my clothes," she groans, and your fingers trail down to her hip. Her hand reaches your wrist and she turns her head to you. "But's that what you want, isn't it?" she whispers. "Let me ask you something. Is it so you can stare at my smooth, toned body, or that everyone else can?" She pulls your hand gently back up to her firm breast, and you jiggle it roughly. "Would you do that where everyone can watch us, John?"

"I would," you tell her. "I'd pull down the tanktop sleeve and expose your perky little tit," you whisper. "Even on a warm beach, you'd get too turned on for that nipple to stay soft. And I know when you felt my fingers cupping it, you'd go as hard as a rock."

"Yes," Jess agrees. "You love watching my nipples stiffen, don't you?" She reaches behind you to grab at your crotch, but you catch her wrist, and bring it to her other breast. She begins to rub her perky boob for you, and your let your hand return to her waist slowly sliding your fingers over the bone of her hip.

"John, I need to cum," she breathes. "I can't believe my boyfriend wants everyone to see my tight, young body on our vacation," she says in an attempt to make you as hot as you've apparently gotten her. She turns to you and the look in her eyes tells you everything you need to know. "But I know that's what I need to agree to for you to make me cum. So if I'm going to give, I'm going to get," she adds.

"I'll parade around in this outfit for you to show me off, like I'm some kind of property," she says. "And I'll enjoy it," she notes, cutting off any response indicating you didn't want to go too far. "But I get to choose the method of my amazing cum. And, if you want me to do this every day, you'll have to give me a mind-blowing orgasm every day. Deal?"
