You used all of your strength to her where you needed!

You needed her! You needed her immediately, but your arms were still tied uncomfortably behind you!

Without thinking you lifted your legs up and wrapped them around the poor girl's head! She tried to fight initially, but stopped when she realized you were trying to guide her towards your fiery clitoris. You could hear her giggle with excitement before locking her lips around your inflamed little nub!

"Slut! I need you!" You hiss down at her through clenched teeth.

Your clitoris had been augmented with three times the number of nerve endings. Over thirty thousand of them screamed out in need as her lips wrapped around your clit. Your legs tightened around the girl's head and your arms quaked against their restraints behind you. Below you, she continued to suck your clit deeper into her whorish mouth where her tongue expertly explored its surface.

"Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuugh! Uuuuuuuuuuuuuuuuuuuuuuuuuuuugh! Uuuuuuuuuuuuuuuugh!"

Your legs gripped her face with more ferocity as the orgasm took you within its painful embrace! The sensation was unbearably pleasurable. There was no relief for your nub as it was continually sucked from the limited protection of its hood within her mouth and probed by the girl's tongue.

"Uuuuuuuuuuugh! Aaaaaargh! Ehhhhhhhhhhhhhhhh!"

Your back arched further off the chair. Pain tore through the bound muscles of your arms and strained back.

"Aaaaaaah! Ow! Ow! Ow! Ow! Ow! Ow! Ow! Ow!"

The sensitivity finally had become to much and you released her head from the grip of you legs. You heard her fall awkwardly to the floor, unable to steady herself with her arms bound behind her back. You were unable to check on her as your core was still racked with intense orgasmic contractions for a few more moments.

By the time you slumped in your chair, orgasm complete, you realized that the entire class had stopped to look at you and the girl still struggling to recover between your legs.

"Congratulations, you two, on completing Oral 101!" You remember Professor Sarah saying while checking off the last items on her grading clipboard.
