Make a bet with her

As usual, Brooke was sweet talking a teacher into a better grade.

Today's victim was Mr. Hoffman. She seemed to be trying her best today, she was wearing a cropped off V-neck with shorts a few sizes too small. Her chest moved wildly with the smallest movement, wearing her favorite push-up bra to really create world class cleavage. Hoffman visibly sweated as she leaned over his desk, her breasts resting on top of a few ungraded papers.

"Are you sure? I try really hard, you know, this stuff just isn't easy for me to learn." She said.

"Be that as it may," Hoffman stuttered, "I can't give you a better grade, Brooke. F-fair is fair, you'll just have to study harder."

"Really?" She pretended to be oblivious about how much cleavage was showing, "Because if I can't pass this class, I'll just have to get a different teacher. After all, if you were a good teacher, I'd learn, and when I learn, I tend to be in a very giving mood."

"I-uh...I guess you're right. I'll have to try harder to teach you in the future"

He never stood a chance.

I tried to catch her as soon as she exited the room.

"Hey, Brooke."

"Get lost, Adam, Nobody wants your pencil-dick flopping around them." She smirked.

"Well that's the thing." Might as well be direct, "I've gained a lot of size, I think I can even out-gun your favorite toy."

"Yeah? You go over and try this with the sluts in Home EC, fuck off, Adam."

"No, really. I can promise you, if you don't fall in love, I'll do all your homework until Graduation."

She paused for a moment. "So, all I gotta do is look at your shrimp dick, and you'll do all my work? Deal, saves me the time I'd take to tease these losers into giving me an A, but when I pull it out, and you can't satisfy a house fly, you're walking home naked."

"Deal."

We decided the girl's locker room would be best, boy's PE got out soon and girls wouldn't be in until after lunch.

"So? This is gonna be fucking hilarious." She laughed as she kneeled down in front of me.

"Only I'm going to be the one who's laughing." I replied.

Brooke yanked down my pants with excitement, but as she gazed on my completely flaccid member, her jaw dropped. She kneeled right next to me, and as my monster got out of its cage, and it rested mere inches from her lips. I could already see her starting to lose control, this was going to be too easy.

"Adam, what the fuck is that?" She said, softly.

I laughed, "You're right, this is hilarious."

She instinctively grabbed it with both hands, unable to completely encircle it. "This thing is fucking HUGE. God, you make every other dick I've seen look like micro-cocks. I haven't seen a cock anywhere near this."

"And it's completely flaccid, aren't you curious how big it gets when it's at full attention?
