Biology Class

“I’m having a lot of trouble in this class,” Celia confessed to her
university teaching assistant, Emily.  “Biology just isn’t my subject.”

“Don’t worry about it,” Emily said.  “I had trouble with this class the
first time I took it, and now I help the professor.  It’s only your
second year in college.  You just need a little guidance.”

“Will you help me?” Celia asked.

“That’s why I’m here,” Emily said.  She moved her chair closer and
rested her hand on Celia’s thigh.  “Let’s start with a basic anatomy
lesson.  Where is my heart?”

Celia pointed to Emily’s chest.  “No, show me.”  Emily took Celia’s
hand and placed it over her breast.  Celia could feel Emily’s hard
nipple poking through her tight red sweater.  Emily grinned at Celia,
her blonde ponytail bouncing as she nodded.  “Good job.  Now where are
my lungs?”

Nervously, Celia pressed her hands over both of Emily’s breasts, her
fingers pointing towards her chin.  “Oooh,” Emily sighed.  “That feels
nice, doesn’t it?”  She put her hands on Celia’s thighs, sliding them
slowly up her short skirt.  “Would you like to continue this anatomy
lesson?”

“Definitely,” Celia said. 

“Good.  Let me show you something.”  Emily hopped up onto the lab table
and parted her legs.  She wore nothing underneath her short skirt, and
her pussy was carefully trimmed, but already shiny and wet.  “These are
my labia,” she said, pulling apart her cunt lips.  “Here is my
clitoris,” she pulled at the bud of her clit.  “Give me your hand.” 
Emily guided Celia’s fingers into her cunt.  “And that’s my g-spot.”

“I thought g-spots were a myth.”  Celia said.  Her fingers were already
dripping with Emily’s warm honey.

“Oh they’re definitely real.  Take off your panties and I’ll show you.”
The women switched places, Celia sitting slightly above Emily on the
lab table with her legs spread wide, exposing her dripping snatch to
her tutor. 

Emily parted Celia’s cunt lips and delicately tongued her clit.  “The
clitoris is really just like the head of a penis, you know.”

“I know, I know,” Celia moaned.  “Don’t stop.” 

Emily laughed and resumed her lecture, stroking Celia’s clit lightly
with her knuckles as she eased her fingers into Celia’s cunt. 
“Personally, I think men say the g-spot is a myth because they don’t
know where to find it.  But I do.”

Celia was squirming, pushing her hips down onto Emily’s fingers, and
her thighs were trembling.  Emily pressed against the walls of her
pussy with two fingers as she continued to stroke Celia’s clit.  “How
does that feel?” she asked.

“Incredible,” Celia moaned, biting her lip.  Emily pressed harder,
moving her fingers in a circular motion, massaging Celia’s g-spot.

“Ooh, ooh, I’m coming,” Celia howled, humping Emily’s fingers madly as
she spurted wet cunt juice all over the graduate assistant’s hand. 
Emily withdrew her fingers and licked them thoughtfully, tasting
Celia’s pussy on her skin.

“Come back tomorrow,” Emily said.  “We’ll do some more work then.”

At four o’clock the next day, Celia entered the biology lab.  Emily was
standing over a table, wearing a short white lab coat and high heels. 
“Back for another lesson?” Emily asked, grinning.

“Definitely.  I’m improving already.”

“Good, because I’m going to give you a little quiz today.”  Emily
unbuttoned the lab coat.  She was naked underneath.  Her breasts were
full, but stood high and proud, and the neatly trimmed pussy Celia had
examined yesterday was again wet and ready.

Celia sat obediently in front of Emily.  “I’d like you to locate my
clitoris.”  Celia’s slim fingers stroked Emily’s clit.  “Good.  And
now, can you find my g-spot again?”  Still stroking Emily’s stiffening
clit, Celia pressed her other hand against Emily’s wet cunt, sliding
two fingers inside.  She felt along the sides of Emily’s sheath,
pressing down until Emily began to gasp.  “That’s it, that’s it,” she
sighed.

“You’re doing very well,” Emily managed to say, but her breathing was
quickening and her nipples were taut.  “Now locate my clit with your
tongue.”  Celia, the dutiful scholar, leaned forward and touched her
tongue to Emily’s clit, and then began to lick, rhythmically stroking. 
“Now I’d like you to locate my rectum.”

Still licking and massaging Emily’s g-spot, Celia slid her other wet
fingers back to Emily’s asshole, pressing on the rosebud until it
yielded and opened for her.  “Oh yes,” Emily said.  “Now fuck my ass
while you eat me.”

Assuming she had passed the quiz, Celia licked faster as she thrust her
finger in and out of Emily’s ass.  Emily was noisy, shrieking and
moaning as Celia slurped at her pussy and fucked both her holes. 
Clenching her thighs against Celia’s ears, Emily came again and again,
until she collapsed and Celia pulled her mouth away from Emily’s
burning cunt.

“How did I do?” Celia asked innocently.

“You’re a terrific student.  But we’ll have to keep meeting to ensure
that your studies don’t get neglected.”

And that is exactly what they
