Jen makes you display yourself to her.

Jen's grin was positively devilish as both of you did the math; it would take nothing more than a shout to have everyone at the party over here staring at your exposed lower body.

At least Jen is only one person; the embarassement would be overwhelming if all four of them stood around looking and giggling...

Fortunately, Jen isn't shouting yet. Unfortunately, she seems to have other plans; plans that don't involve handing over your shorts yet.

Instead, she strolls over the edge of the pool, laying your swim trunks out on the ground and casually taking a seat on top of them. With her bikini-clad ass resting on your swim suit bottoms, your chances of snatching them go from slim...to none.

Giving a meaningful look over at the rest of the party, Jen crosses her legs and motions you to move your hand away from your groin.

You hesitate, unwilling to bare yourself so openly under Jen's intense gaze.

An exaggerated inhalation from the asian girl drives home her unverbalized threat though... you pull your hand away, giving Jen a clear view of your shamefully erect manhood bobbing about in the water.

Jen licks her lips suggestively and has a brief fit of giggles as you're **** to stand on display for her. "Now then, John... what kind of performance should I have you do in exchange for these?" Jen pats the swim trunks she's sitting on, musing to herself out loud while eyeing you up and down with a mix of amusement and a somewhat frightening predatory air.
