Her project is a machine... thing.

You waited in silence with Tammy as she fidgeted in her impossibly skimpy apron. There wasn’t anything for you to do but look at this little nerd’s 'assets', until one of the fair’s judges came by. And come by one did, when miss Villagomez strutted up to Tammy while the shy nerd withered in shame. That was actually a bit surprising, wasn’t miss Villagomez a music teacher? Eh, either way, you had wet dreams about her sometimes. Even if they were really weird ones, like that one time Villagomez was dressed like a Disney Princess and jacked you off with a pair of cookies before drinking your cum like milk.

Okay, maybe pretend you didn't share that specific dream. Even though it was sexy as all Hell when it happened. Whatever. Like Tammy, the cute music teacher didn’t have a lot going on in her bra cups, but unlike Tammy, Villagomez still had at least a pair of B-cup boobies. A beautiful C-cup on the days she wore a push-up bra, and all that ogling you did in class might’ve been why she seemed less than thrilled to see you ogling her right now.

“Hello Tammy, Sam. It’s time to begin your presentation, could you please explain to me what your project is?” Villagomez asked, but in such close proximity to a teacher, your half-nude pranking victim froze like a fern in the Arctic.

Tammy just stood there and wheezed for a good six seconds… until you gave her pale, bare ass the slap of a lifetime.

“Eeeek!!” She squeaked, turning back to face you before realizing how bad an idea that was. The poor, humiliated nerd slammed a hand over her cute bottom and shuffled back to face Villagomez while the gymnasium exploded into laughter.

“What? Tammy wasn’t saying anything.” You said, explaining your spanking in plain terms.

“That was uncalled for, Sam.” The cute adjudicator gave you a stern (yet sexy) look as she asked the mortified Blondie once again to explain her science-y shit. "Please, if you could begin, Tammy."

"M-m-my project is a m-m-m-m-machine that converts rot-t-t-tational energy into th-thermal energy, and blah blah blah, yadda yadda, I have the tits of a plank of birch wood, and I think Sam is totally into me..."

You tuned out the adorably shaking, mortified geek's big, funny words until she turned her beet-red face to you. You snickered as looking in your general direction meant Tammy was flashing half the student body her bare ass, but then she said, "Y-you have to get on the m-m-machine Sam. Y-you agreed, agreed, to pedal it for me."

Shit, that's right, this nerd actually roped you into doing her tiny-titted ass a favor. You didn't put up any fight (knowing it could cost you a lot of homework), and hopped onto the jury-rigged exercise bike, while you silently tried to come up a way to make this dumb science fair more... fun.
