Shin Marvery [Probably Illegal]

Mary avoided Avery's look. That look always made her feel weird, uncomfortable. She half-closed her eyes, raised her brows, smiled and whenever they made eye contact she would lick her lips as if she was hungry.
Blair always laughed when she asked what was going on. Usually with a "You're too innocent, Mary".
She just didn't understand.
It was late at night. They should have been sleeping an hour ago but Mary needed to do some homework.
But Avery didn't, so, why did she look at her like that?
Why was she awake?
Why was it that she felt so much pressure?
She rolled on her bed to look at her directly. She was on the lower bed of the bunk-bed, Avery was on the stand-alone bed at the other side of the room.
The moonlight made everything look like silver.
Avery licked her lips and got up. She walked slowly towards Mary's bed. Her heartspeed was raising like crazy. Why was she so nervous?
There was something about the way she walked, the way she... Stripped?
Avery was taking off her pants and shirt, with only the underwear remaining.
Mary immediatly turned to the wall. "If i don't look, it's not there" she tought.
It didn't work, as she felt Avery getting on her bed.
She didn't know what to say, she was afraid.
A shiver ran down her spine when she felt Avery's hand touching her butt. She made one finger explore all of her ass line, stoping where Mary's closed legs forced her to.
Mary was blushing pretty hard, and felt intimidated.
Avery's hand grabbed one of her hams and kneaded it pretty hard. She pressed her lips, it wasn't an unpleasant feeling. She didn't understand why Avery was doing it.
She was breathing at her neck, but in a second, she raised her head and put it besides her's, then kissed her in the cheek. Mary... liked it?
Avery started to move her hand upwards through her body. She slowly raised her shirt and made a single finger mark circles around her navel. Mary trembled a little, she was ticklish. Then, she moved her hands again. Mary always slept with a bra on, she was just used to it. So Avery was forced to go under it and start playing with her nipple.
Mary realized she was enjoying it. What was it? Why was she enjoying something so... impure?
She moaned a little, but tried to restrain herself in order to not wake up Blair.
Avery stopped with her boob. Mary was feeling warmth between her legs. Avery forced her right hand below Mary's body and, with a quick move, made it so that they were face to face. Meeting eye to eye, Avery kissed Mary and used her hand to keep her in place. But Mary didn't fight it.
Her lips moved on their own, rubbing and sucking. When Avery used her tongue she met it with her's and they kissed like that until Avery decided to stop. After staring her intensively for a few seconds, Mary felt her hand slip down to her crotch. She opened her mouth, wanting to say something, but didnt. She could feel a finger exploring her wet and slightly opened pussy.
She pressed it just enough to entice her. It felt good, too good. Mary covered her mouth with a hand, not wanting to make noise. When she tried to close her legs tight, Avery used her own to stop her.
Mary was contracting her muscles and when Avery made one of her fingers go in, she squeezed it. Her breathing was heavy and the only thing she could think was "please don't stop".
In a sudden movement, Avery started to trace circles inside her. It was making Mary go crazy.
Then, another finger got in.
Both started to go in and out, without rhythm. Sometimes fast, sometimes slow. Even if it seemed random, it was precise.
Too precise.
After a minute, Mary let out a silent scream and Avery felt the sudden wetness and warmth all over her hand. She smirked and went back to her own bed.
Mary wanted to say something, but couldn't.
She fell asleep.
Avery murmured something, even if Mary wasn't listening.
- If you ever have trouble sleeping again, i'm here for you.
Then, she herself slept.
