Despite your best efforts

There's no way you're giving these bastards the satisfaction. Last time was a fluke. It was an unexpected situation and you had an unexpected reaction, that was all. Joy is not some pushover of a whore who cums just because some dweeb gets his dick in her. Now... how do you stop Tom from fucking another orgasm out of you when his cock feels so fucking good!?

Your resolve falters briefly when he gropes one of your tits, eliciting a loud moan from you, but your head clears (somewhat) and you focus on the task at hand. You've never tried NOT to cum before, but boys do it all the time, right? Don't they usually think of boring stuff, like baseball? Yeah, boring old sports! A baseball player just standing there holding a bat. Fit, in uniform, dripping with sweat from the summer heat... This is just making you more wet!

"Dude, she's totally soaked down here! I think she wants to cum just as much as we want her to!" Tom taunts. He's wrong! But it sure wouldn't seem like it from his perspective... As a last ditch effort, you begin counting sheep to distract yourself. You barely make it past 10 before your counting syncs up with the moans being pumped out of you, and you're dragged back to the reality of being stuck on Tom's shaft.

You take a deep breath, as if holding your breath would help. You're already on the brink when Tom has an idea. "I'll bet a slut like you just melts if someone rubs her clit." Wasting no time, he reaches down and finds your clit with ease, and the second he touches it, the world goes white. Your eyes roll back, your toes flex for all they're worth, and your tongue lolls out of your mouth. You'd certainly feel ashamed of the pose, if your brain was processing anything other than a pleasure overload. Somewhere in the back corner of your mind, you're annoyed that trying not to cum has given you the most intense orgasm of your life, and that Tom has earned the right to say he gave it to you. But you're mostly preoccupied with crying out in euphoria as Tom fucks your straight through your climax.

Once you can manage to think again, you hear the tail end of Jerry and Tom discussing something. You don't really want to know what, but it seems Tom intends to tell you anyway. "Okay slut," Tom starts, earning another spasm from your oversexed cunt, "we want you to apologize for being such a fucking bitch. And then, we want you to admit that you're nothing but a cocksleeve who's been waiting her whole life to be put in her place." To make his point, he gropes one of your tits again, this time making you moan even louder than the last.
