"... I can make you cum."

Donna's stomach knotted itself over, there was that predatory intent she felt from Grace.

"Put your hands against the wall." Grace ordered, Donna did as such, she felt her legs being kicked out from under her, so that they were now spread wider.

She felt a hand glide over her naked back, tracing a line across her spine and arriving at the small of her back, the hand jumped away, and before Donna could wonder what happened to it, she felt a sharp sting against her ass cheek, followed by the hand squeezing tight on it, she yelped in surprise, something that sent Grace's two friends seemed to find amusing as they giggled to themselves.

The hand crept back up, this time along her side, Donna tried her best to not get ticklish, until the hand reached her breast, where it began massaging, twisting and pinching her erect, pink nipple, which **** a soft moan to escape from Donna's throat.

"Why, I think Donna's happy to see me." Grace quipped, earning a second round of giggles from her friends.

Donna waited for the hand to creep back down and begin toying with her now bald pussy, the thing was engorged, aching and most likely dripping enough to cause a slipping hazard, what happened was probably preferred as Grace began employing her second hand, she felt a finger glide across her outer lips, sending a jolt of joy down Donna's spine, Grace's finger continued to brush back and forth, only barely parting her juicy labia.

Donna was going crazy with Grace's teasing, she wished she could just take her hand and jam it deep into her hungry folds, but Grace seemed to relish the chance to humiliate Donna even further:

"Beg for it." Grace simply said.

"W-what?" Donna didn't quite understand what Grace had said at first, she was too lost in lust to hear or think straight.

"You want me to keep going? You have to beg for it." Grace chortled at Donna's lightheadedness.

"U-um... Please, do it?" Donna was clearly unable to think straight, she rocked back and forth with each brush of Grace's fnger, she had her eyes closed and was beginning to lick her lips.

"Do what? Tell me specifically." Grace still refused to release Donna from her horny limbo.

"Please fuck me with your fingers... Make me cream myself... All over the floor..." Donna was now panting, the shame and humiliation of having to ask her accoster to violate her was too much.

"Well, if you ask so nicely...." and finally did Grace decide to heed Donna's pleas, she plunged her index and middle fingers deep into Donna's sopping wet snatch, Donna gasped with ecstasy,and as the fingers began pumping her rhythmically, probing and bumping against her special spot, she felt her orgasm approaching fast.

"Turn to look at me, Donna." Donna heard Grace's order, she turned back to see why only to be surprised by Grace's lips coming in for a deep-tongued kiss, forcing her way past her lips, exploring her mouth and tangling with her tongue, just as her fingers were probing beyond her other lips.

At first Donna resisted purely out of reaction, but she gave in, the passion and heat of the kiss seemed to melt her insides, which manifested in her exploding into orgasm, her body convulsing in pleasure as her hips bucked, juices gushing and trying to **** themselves around Grace's fingers and out to the open, knees buckling as energy left her legs.

"Well Donna, I certainly had fun!" Grace laughed a ringing laugh as she presented her cum soaked fingers to Donna "now clean me up."

Donna couldn't stand the humiliation, she wanted to swat away Grace's hand, but once that switch had been flipped, she really couldn't help it, she opened her mouth and engulfed Grace's two fingers in her mouth, bopping her head back and forth as if she was giving a blowjob, she could taste her own cum juice, sour and coppery, and the humiliating thought only seemed to get her pussy tingling once more.

"Oh, we made a video of the whole thing if you don't mind," Grace bent down to give Donna an easier access to her fingers "Not going to **** you or anything, don't worry, just personal."

"Besides, half the school already seen you naked," Grace threw in that backhanded comment, once again compounding the shame as Grace removed her now clean fingers.

"Can you send me a copy?" Donna couldn't believe what she was saying, it was almost like she was a different person altogether, the girls cackled uproariously.

"Sure thing, honey, let's do this again." Grace said as she and her friends left Donna alone, at long last.

Once she regained her senses, Donna immediately retrieved her gym uniform and...
