Beth's conjecture bore out, John seemed distracted by the idea of playing out on the porch, he'd telegraphed his throws and didn't notice Beth, who'd been very good at Rock Paper Scissors, who was delaying her throws until the last possible millisecond.
The result was a naked John, his hard cock flopping in the breeze as he stood there on the porch, when he tried to cover, Beth scolded him and told him to keep his hands at his sides.
"So now, you're gonna take these five boxes, right John?" Beth set out the boxes John had promised to buy.
"Beth please, I can't, I'd be broke!" John pleaded, for some reason being at the mercy of a girl six years younger than him, naked, humiliated and completely outmatched, all of that made his erection unbearably hard, something that was not lost on Beth.
"Nope, you promised, and you have to keep your word, but I'm not heartless, I'll make you one more deal." Beth giggled, enjoying the control she had on this boy much older than her.
"Anything, what do you want?" John knew he was not in a position to argue.
"One more game, if you win, you can take the five boxes for the price of one, and I'll even get naked for you," Beth walked up to John, put a finger on his cock and pushed it down, letting it bounce and flop freely when she let go "but if you lose, you give me the price of one box, which you don't get by the way, and jerk off for my phone's camera, right here on the porch."
John was distraught, he was being blackmailed by this barely teen girl, and he had no choice but to accept, hoping he could eke out a victory.
