Her legs began to tremble a little bit it wouldnt be long before they would be unable to support her and she would fall to the floor. Managing to stutter out "H..how ooh..are you doing this" she moaned as she spoke

"Your species calls it psycokinesis, I did say I was highly evolved... physically I'm little stronger than an average human girl... I make up for that with my mental prowess."
The rip in it's face returned and it smirked slightly to her it lifted it's hand and it shifted it's shape itno that of a blade; she'd feel the weight of her body lift off her legs, gravity barely having an effect on her now. it's fingers became small blades and her panties repaired themselves taking their normal shape. even hovering above the ground her legs stayed clenched together it wouldn't force her yet; if she decided to resist however... that would change.
"I can change my shape, control mater around me; I don't breath and live forever... what many would call the pinicle of evolution. yet I'm usually quite unhappy..."

She gulped seeing the blades, at first wondering if leaving her staff with her clothes was a mistake, but relaxed seeing what it was doing with them. She blinked a bit amazed, distracted from the pleasure that was still washing over her body.

Arith ran the blades along yuki's stomach going up towards her bra the blades didn't even scratch her skin.
"I have no gender either... not male or female... I just take whichever shape suits my mood..."
It said the room became slightly colder as arith's body twisted slightly, it's hair became longer, waist became smaller, it gained a bust and more of an hour glass feminine shape.
"Do you like my fem form?"
It asked as the blades reached the small piece in the center of her bra, the blades severing the pieces from eachother taking the center bit of material in it's hand and examining it slightly, however her breast didn't burst from the cups, they remained as if trapped the tentacles pulled away from her body teasing for a minute before they returned to their manipulations a few hair like tentacles slipping down her panties and up between her nether lips lightly massaging her tunnel.

She moaned lightly arching her back starting to get wetter she tenced up "I..its cute mmmn.." was all she could mutter.

Arith nodded to yuki's response examining her bra curring it off slowly and tossing the pieces into a pile until all that remained on her breasts was a small circle over her nipples. It was toying with her now the hairs in her tunnel kept stopping at random keeping her from orgasm near perfectly keeping her on the line using her mind to tell it when to stop.
"Do you like being teased?"

She bit down hard, cutting her bottom lip. "Mmn. I do..don't mind it but..mmm if you keep bringing me so close then backing off...You'll drive me insane " she muttered softly her juices starting to drip down her legs.

"Can't have that now."
It voiced the hairs began to play again seeking the one spot that would easily make her reach her first orgasm.

She gasped letting out a loud moan feeling the threads press against her G-spot, she tenced up her legs trembled slightly as she cryed out coming to her first climax.

Arith's skintone seemed to shine a bit more as she climaxed it smiled and nodded.
"well then, lets keep going."
the bladed fingers flicked off the two circles of material that were still on her nipples then traced down to the sodden material that was her panties, it's mouth latched lightly onto one nipple and lightly played with it flicking over the nub with it's tongue. the blades traced over the waistband once down one hip, then down the other, the hairs retracted ffrom her tunnel as the pnaties were severed. then arith slashed at them, they burst to little scraps of material leaving her finally nude infront of the creature. the frigid air of the library caressing her wet exposed skin.

Her body flinched every so often under the actions the creature took, she bit her lip moaning the sucktion on her hard pink nipples sent a wave of pleasure over her, she was already sensitive from the teasing, starting to lose controll over her voice now.

"You don't need to talk, just thing of anything you want me to try..."
Arith told her mind a tentacle shifted shape and took the place of it's mouth on the girl's nipple a hand rubbed against her clit before placing a thumb on it.

She moaned loudly closing her eyes tight, her body seemed to flinch each time the monster added another point of stimulation, her sex dripping wet now she started getting embarassed.

"Ahhh, a pinnicle of your species emotionally."
It told her as her body lifted into the air alightly further the room chilling more as it grew to roughtly three times her size two tentacles wrapped around her arms from wrist to shoulder and they did the same with her legs though these had off feather like tips that rested against her netherlips shifting slightly every few seconds. Arith had decided to play with her feelings a bit more before actually exploring her body fully.

"Th..this is embarassing" she blushed shyly looking down at it then glancing to the window, thinking if someone just happened to walk by...
