Test of endurance!

"OK slut, hands up," Lawrence demands.

Mortified, you obey, your tits tightening as you lift your arms over your head.

"Good girl," Lawrence coos. "Now place your palms against that tree again." You follow his orders. "Now take a step back. And again. Keep going..." You find yourself leaning hard against the tree now, your arms far outstretch, while your thighs strain to hold your body upright.

"That's fine," Lawrence declares. "And remember, your hands have to stay glued to the bark for five minutes."

This time, your arms are burning in less than a minute. You're shifting your weight from leg to leg, but you don't dare step forward to release the pressure on your arms. Unsurprisingly, you once again feel Thomas and Lawrence groping your ass, squeezing your boobs, and playing with your pussy.

"Fuuuuuuuck, Larry," Thomas whispers, his finger buried in your pussy. "This bitch is wet."

"Let me see," Lawrence says, adding his finger to the fat nerd's. The two fingers playing inside your pussy from different angles are driving you wild, but the strain on your arms is killing you.

"Shit, this bitch _is _a total slut. I can't believe she's getting off on this." One finger pulls out, and one goes deep inside you. A moment later, you smell your own sex as Thomas shoves his fleshy middle finger, wet with your juices, into your mouth. "Lick yourself clean, dog," Thomas chuckles, and you have **** but to suck your wetness off his finger.

"Hey, here's a good one," Thomas says, his finger still in your mouth. "What's the difference between a bitch and a slut?"

"I don't know," Lawrence says, steadily fucking you with his finger.

"A slut fucks everyone, and a bitch fucks everyone but you."

Lawrence laughs, and you literally gag.

"What the fuck?" Thomas says. "You didn't think my joke was funny? Or you just can't tell which one you are?"

"Ha, nice," Lawrence says.

"Hey, here's an idea," Thomas says, finally pulling his disgusting finger out of your mouth. "I know how to make you laugh!"

And before you have a chance to even think about what he could mean, the fucker starts to tickle your exposed armpits. You do, indeed, laugh, and you press your hands firmly against the tree trunk.

"Nice one!" Lawrence calls, also pulling his finger out of you and joining the fun. The boys run their hands all over you, tickling your armpits, squeezing your thighs, brushing your nipples. The sensation is overwhelming, with the arousal in your pussy and the fire in your arms. But you're determined to outlast them.

Eventually, they seem to tire of torturing you, and the tickling stops. You wait, the silence almost as agonizing as the catcalls. You venture to speak, "Excuse me, Sir. How long has it been?"

"What?" Lawrence says. "Oh, I forgot to keep track. Let's just start the timer now. Five minutes to go, slut!"

You moan as the seconds slowly tick by. The total silence from the two teenagers haunts you and forces you to focus on your intense discomfort. You're certain it's been more than five minutes ... but then you realize that you are absolutely powerless to raise the issue. It will be five minutes when Lawrence says it's five minutes and not a moment before.

Suddenly, there's a rustling underneath you. Thomas is sliding under your arms, bringing his face close to yours and before you can stop him, he's kissing you right in the mouth. His breath stinks, his sweat clings to your face, and his tongue forces its way into your mouth. Instinctively, you rear back, pushing him away with both arms.

And then you realize that you've fallen into their trap once again.

"Oops," Lawrence calls playfully. "And it really was almost five minutes just there."

"Too bad," Thomas says, his grin still glistening with your saliva.

"I guess we'll just have to try something else to whip this bitch into shape."
