She needs help with her science fair project.

“I n-need some help with my presentation at th-the science fair, and I was k-kind of hoping… you could help me with it, Sam.” Tammy asked while looking everywhere except at you. She was standing close enough that you could reach out and grab her hands, so you caressed them; knowing that the best way to avoid her ridiculous requests was to get her flustered.

"Aww, I'm so sorry Blondie, but I think I've got something that day." You lied while you pulled her over your lap, watching Tammy blush as her skirt began to creep up her legs. More importantly, you got a view down the nerdy girl’s graphic tee. You took in the hilarious sight of Tammy’s teeny-tiny titties, and the poor blonde squeaked like a church mouse when she realized where your eyes were.

Hands clamped over her chest, and face turning red like a strawberry, Tammy said, "This, is uh, very important for me, Sam... I really n-need your h-help here..."

"Are you sure it needs to be me?" You asked in your sultriest tone, even slipping Tammy's clammy hand onto your bare chest. Your lips grazed the exposed skin on the petite nerd's neck as you suggested, "I'm sure Abigail would be happy to help you out."

"N-no, she's g-got her own entry... c-c-c-come on, Sam, it's just one day." The mousy little lady was stuttering like crazy, and her face was hotter than a furnace, but she somehow hadn’t backed down on that favor— not even as you teased her skirt up to her underwear. Realizing that your usual tactics of just overwhelming the hopeless fool with smoldering eyes might not work here, you changed your course of action.

For the first time in a while, you conceded to return the favors you took from her so often. "Aw, can't I get any pranks past you Tammy? Of course I'll help you with your science... thingy. What kind of friend would I be if I didn’t?”

The words felt like bile rising in your mouth, and though you were certain she could see your grimace, the little geek on your lap smiled like a twitterpated fool as she said, “Really? I-it’s in a couple of days, th-thank you so much Sam! Live l-long and p-p-prosper!”

You helped Tammy hop off your crotch, and silently resented her for actually managing to wrest a favor from you after all this time. Although you knew flaking on this stupid science fair could cost you all the homework she was so easy to fool into doing, that didn’t mean you couldn’t have some… ‘fun’ with her on the job. Oh, you were going to have buckets of fun with this little dork. Hey wait, why was your lap so damn wet? Try not to think about that, focus on this stupid fair...
