Finger Keira behind the bookcase

Your hormones take over as you pin Keira against the cold stone wall, parting her lips with your tongue, she eagerly wraps her tongue around your own. The citrus scent of her perfume only makes you desire her more as you brush your hand down her hip and onto her bare thigh. She wraps her leg around you as you subtly slide your hand up her thigh and underneath her skirt, giving her ass a gentle squeeze.

'Wait what about Liam?" You ask in a brief moment of lucidity.

" We have an arrangement." She gets out as she tries to catch her breath. She reaches for your hand, pulling it off her bum and guiding it down to her damp mound. You instinctively rub her and feel your finger slide between her lips, separated only by a thin silk fabric. " Now, do you really care?" She whispers into your ear before tenderly nibbling at it. Without a word you slide your hand into her panties and drive your fingers inside of her. She lets out a loud moan as her warm cunt tightens around your fingers. You thrust your fingers in and out of her frantically, unsure of whether you're doing it right. She takes hold of your hand and the two of you pause. Keira kicks of her panties to the side and leads your fingers back inside her. This time however she instructs you on how to tease her clit with your thumb as you slowly work your fingers inside her.

The motions of your hand are much more coordinated this time, and her increasingly loud moans imply she's enjoying your new level of finesse. Keira pulls your body closer to hers with one hand as her other hand makes its way down to your crotch. She runs her fingers over your pants, along the length of your hardening manhood. "Oh god you're so hard." She says as she gives your cock a squeeze.

"I want to fuck you." You tell her as your free hand pushes up against her breast. giving it a soft squeeze.

" I want to fuck you too." She says before releasing her hold on your manhood. "But that's not part of my arrangement." She gives your lips a gentle kiss. "Trust me darling, at this moment I want nothing more than to push you onto the ground and ride your dick but rules are rules." You accept and continue to grope at her body and rhythmically pleasure her with your fingers Her moans echo in the library as she arches her back, begging for you to go faster. You oblige, rapidly thrusting into her until finally she lets out an extended moan, you feel her muscles constricting around your fingers, her body spasms as she grabs hold of your wrist, wrapping her thighs tightly around you as juices flow out of her.

She collapses to the ground in exhaustion. her face is a bright pink and beads of sweat line her forehead. " You definitely score a 108 in sexual potential." She comments. The two of you laugh. You continue to ogle her as she bends over to put her panties back on. The two of you get back to work and make small talk for the remainder of your library duty. professor Dove returns soon after and excuses the two of you for the day. You walk together to the central lobby before parting ways. Keira gives you a kiss on the cheek and promises you'll hang out soon. She also hands you a small book out of her satchel as a gift. She says it's a thank you for earlier.
