Emi rode Fumiko's face

As Emi kissed Fumiko passionately, their tongues rolling around each other's and mixing the taste of Fumiko's juices within their mouths, she reached her left hand down to pull her skirt and panties over her thin hips and ass. Unconsciously, she wiggled her ass, using the motion to get her clothes down her legs and past her knees. Kicking them free, she broke the embrace with Fumiko and pulled far enough away to look down at her coworker.

"That was amazing," she said as she used her right hand to stroke Fumiko's cheek. "But I think we should try something else."

Fumiko looked deeply into Emi's eyes with a strong, churning lust. “Anything, Emi. I want to make you cum.”

Emi smirked playfully. She climbed on top of Fumiko, spreading her legs apart as she lowered herself until she felt Fumiko’s tongue glide across her pussy. Emi let out a soft moan, her body trembling as she felt Fumiko’s tongue explore her folds, opening up her labia and tasting the fluids that had been leaking out of her since the moment her eyes fell on her coworker standing in the doorway. Placing her hands on the top of Fumiko's head, Emi started moving her hips, grinding her pussy against Fumiko’s face as she felt her orgasm build.

Fumiko’s hands reached up to Emi’s ass, pulling her closer as she inserted the tip of her tongue into Emi's opening. Emi moaned louder, feeling Fumiko's tongue push through her opening, penetrating her. Despite never having been with a woman, Fumiko knew just what to do, curling the tip of her tongue to touch as much of Emi as she could as pulled it back out.

"Fumi," Emi moaned into the empty library as her back arched and she gave into the feeling of her building orgasm. "That feels-"

Emi's words were cut off by a squeak as Fumiko opened her mouth wide and took all of Emi's pussy between her lips. She moved her tongue first around the outside of her labia and then through the middle of her slit until it came to up to her clit. Fumiko made circles with the tip of her tongue, teasing Emi's pleasure button out from its cover, and as she did, Emi stopped moving and began to quiver, poised in position over Fumiko's face.

Realizing that Emi had stopped moving, Fumiko tightened her lips, closing them in a sharp circle around Emi's clit. She sucked it in deeply and used her tongue to flit over the top of the exposed head over and over again, slowly at first, causing Emi to open her mouth and moan, but after what seemed like forever to Emi, Fumiko got faster. Emi gripped a handful of Fumiko's hair, feeling her orgasm coming, Fumiko stopped.

"Ah?!" Emi grunted in confusion, looking down at Fumiko's eyes.

Fumiko looked back up at her with a playful squint before she began rocking her head. Emi felt Fumiko's flat tongue move from her opening to her clit, causing an electric pleasure to move up her hips slowly, sparking each time Fumiko's tongue struck her exposed clit. The electrical warmth rose slowly up her body, up her hips, through her back, and by the time it reached the middle of her chest, she knew that Fumiko was building her to an intense orgasm. By the time the feeling reached Emi's head, she knew that she would explode.

Emi's back arched and she unconsciously bit her lip as the feeling rose up her body. She felt the skin between her eyebrows clench and she knew that if anyone were to see her now, she would be ashamed of the lewd look on her face. Fortunately, Fumiko's face was covered by her hips, meaning she was the only one who knew what she looked like. Despite feeling nothing but the electricity sparking across her skin and up her spine, Emi's hips moved uncontrollably, aiding Fumiko as the feeling of her orgasm began to tingle in her neck.

Just when she thought the feeling was going to touch her head, Emi felt pressure on her anus as Fumiko pressed a finger against the sensitive edges of her opening. As she did, Emi felt that warm, electrical feeling explode into her brain. All of her muscles tensed at once and she screamed into the empty stacks, cumming hard on Fumiko's face. She pulled her coworker's head roughly against her body as the orgasm rocked through her, causing wave after wave of the sparks to flash from from her hips to the top of her head, leaving her body through the tips of her hair.

As the feeling subsided, all of Emi's relaxed into gelatin. She fell forward, crumbling into a ball on her side just above Fumiko's head, and laid there as her heart calmed down. She breathed haggardly and let her breath leave brief moments of fog on the cold tile floor.

"Emi," Fumiko purred, moving up to Emi's body.

Emi only panted in response before turning her head to look up at the woman above her. In response, Fumiko leaned in and began kissing Emi, mixing her fluids into Emi's mouth like she had done with hers just a few minutes before. Emi responded, feeling the desire rising up in her stomach again. She knew they weren't quite done yet.
