Give him something special instead.

You ask him if he's seen a girl naked before, or if he's been with one sexually. He shakes his head, embarrassed to admit it. You decide that there's another way to get those pictures away from him, and you won't have to lose any of your clothing. You just need to tease him a little bit. Both of you stand behind the bench, and nobody seems to be paying much attention this direction.

Slowly, you pull up your skirt, showing off your smooth lengthy legs, though you stop just before your panties. You suggest that maybe there's another way you could make a deal. You watch in joy at him struggling to contain his arousal.

"Maybe..." he mutters.

He appears to be short on words. Dropping your skirt back down, you gently squeeze your own chest, allowing them to jiggle up and down in your grip.

Clearly this boy has very little experience with women. He grips his own groin in agony at the teasing. You step closer, bottom halves still completely concealed by the bench. Your hand gently caresses the very obvious erection protruding from his pants. He practically jumps at the touch.

"We'll call it even after this... That's fine..." he whispers, seeming to be off in his own world of pleasure. As you rub your hand up and down on the front of his pants, you wonder if he might simply orgasm from this. You don't want to be too mean, so instead you look around, and then slip your hand down the front.

As you stroke his cock, he squeezes the top of the bench and groans. This was probably the first time he's felt a hand other than his own on his cock. Up and down you bring your hand. You're impressed at the size honestly, but you remove those thoughts from your head. You just want him to delete those pictures, and this is the quickest and easiest way.
