Professor McGonagall wrapped her lips around one of the pink erected buds and pressed a thigh tighter to the apex of the girls legs. Hermione bucked her hips slowly against the surprisingly taught thigh. McGonagall bit gently down, eliciting a small cry from the girl.

There was a soft knock on the door, but Hermione couldn't have been any more oblivious to it than when it opened. She though she heard a cry, Minerva entered the room and shut the door behind her. She took another step and gasped at what she saw. Hermione sat up against the wall on her bed with her knees bent and a pillow clenched in her left hand. Minerva stood in shock and arousal as she watched the girl's digits slip in at out of her genitalia. Bitting her bottom lip, Minerva's breathing rate increased as her fingers clutched the sides of her robe. Hermione whimpered softly.
"Minerva..." whispered the girl hotly. Moistening her lips and noticing that metalic taste from her skin, Minerva couldn't take anymore. She moved over to Hermione and lowered herself to press her lips against the girls ear.
"Need help?" Minerva sat down pressing her body to the 19 year old. Hearing Hermione gasp in shock, the older witch smiled.
"Min-Professor... I'm sorry... I-I Oh, Merlin!" Minerva slipped her hand onto the young witches thigh and dug her finger nails into the flesh.
"You excite me Hermione. I couldn't get my eyes off of you, but then you said my name..." Minerva stood up and pulled Hermione down to lay flat on the bed. Spreading the girls legs, Minerva settled between them and began kissing Hermione's inner thighs. "May I?" Minerva placed a tender kiss against Hermione's folds. Accepting Hermione's bucking hips as a 'yes', Minerva separated the folds and encircled the small bundle of nerves with her tongue. Hermione entangled her fingers into the bed sheets and groaned. Feeling Minerva chuckle against her caused her hips to start a slow grinding pace. Minerva's lips wrapped around the erect clitoris and flicked her tongue over it repeatedly until she felt Hermione's hips rise off the bed. Moving slightly lower, Minerva teased the girls entrance and pressed her tongue inside.
"Fuck!" Hermione cursed.
"You're going to wake up the whole house!" Minerva smirked and continued the slow pace of her probing tongue. Feeling the girl begining to tense, Minerva stroked the girl until the convulsions eased.
"I knew you had a wicked tongue." Hermione panted with a grin. The older witch settled on top of Hermione only to roll over onto her back. "My turn, dear." The older witch smiled and realized this was only begining.
