Chapter 4

The walk back to Cameron's apartment felt endless, the silence broken only by intermittent conversation. Both women knew how this night should end, with a goodbye at the door. They walked separately, both conscious not to touch the other after the events at the restaurant. Somehow they could blame that on the wine, the atmosphere, one friend reaching out for the other, not entirely platonic but the actions of two lost people searching for something. But the coldness of the night air had brought with it the clarity of the situation, the responsibilities and the consequences.

Thirteen's head was spinning, as she tried to keep all sexual thoughts from flickering across her vision. She bit her lip to distract herself from the sudden image of pinning Cameron against the wall that she had imagined earlier that night. Cameron, walking alongside her, was similarly attempting to ignore the seething desire flooding her body with previously unknown longings; she felt parts of her body she didn't even know existed come alive with a thirst she'd never felt before. She couldn't even look at Thirteen, one glance at her hands, her long nimble fingers, left her aching with imaginings of the things they could do to her.

They slowed as they approached Cameron's apartment.

"I'll walk you to your door," Thirteen suggested, and followed Cameron up the steps to the apartment door.

Cameron turned around, her big eyes pools of darkness and expectation. She knew Thirteen would be able to see her chest rise and fall, and yet she felt she couldn't breathe as she looked at her.

Thirteen knew she had to do the right thing, she knew she had to step away. The blood pounding inside her head, filling her ears with a surreal, deafening sound heightened all her other senses. She could almost feel the air Cameron was breathing against her face, her eyes caught the full, moist texture of Cameron's lips and she knew that this was the hardest decision she would ever make.

"Goodnight," she said firmly and sadly, "and thank you for tonight. I had a wonderful time."

She tried to ignore the look in Cameron's face as she spoke, the disappointment that was so evident in the soft drop of her mouth, the fading sparkle and shine of her eyes as her hope ebbed away.

Cameron hesitated, "Yes, Goodnight, and thank you." She paused, her voice breaking slightly, "I guess I'll see you on Monday."

"I'll be there." Thirteen replied. And as she turned, she felt almost as if there was an invisible force making her movements slow and difficult, a magnetic strength pulling her back, drawing her in.

She stepped down the first step backwards, still looking at Cameron.

Cameron slowly closed the door as she watched Thirteen leaving.

Thirteen felt her feet hit the concrete of the street below, unaware of how she got there. What was she doing? Was she actually throwing away a chance with the only person who had ever cared and with whom she felt special, normal, right?

Her legs were propelling her up the stairs before she even knew she had made a decision. She had no idea why she was running. Her breath became more than rapid and she knew she needed a whole lot more oxygen than she was currently inhaling. Her hand trembled as she reached up and rang the doorbell. There was a noise from inside, an unlocking of the door.

Her eyes met Cameron's for a second, and then they were kissing, hard. Thirteen's hands tangled in Cameron's hair, her hands pulling her closer, pulling her mouth more onto hers, her lips pressed more against her own, their tongues clashing for dominance. Their breath merged as they both gasped into the kiss, fighting for air but unable to stop. Thirteen pinned Cameron against the door and Cameron moaned into her, at Thirteen's body pressed against her own, at the feel of her chest against hers and her hipbones meeting hers in just the right way.

Cameron felt her hands on Thirteen's face, her neck, stroking her and gasping into her hair as her body came alive at Thirteen's touch. She felt her body begin to hum and tingle, lower and lower as Thirteen traced kisses over her neck, her jaw line; her body shuddered as Thirteen kissed her way up her chin, and when their lips met again, not even kissing but just touching, open, breathing into each other as if they didn't know where to begin.

Thirteen's hands were on Cameron's waist, moving downwards to the hem of her top, and reaching inside, her fingers dancing along Cameron's taught abdomen, the muscles quivering under her touch as she reached the top of her pants, sweeping over her hipbones. Cameron moaned involuntarily, and Thirteen laughed softly into her hair.

Cameron suddenly grasped Thirteen's hands, and walked Thirteen backwards, pinning her arms up above her head and against the wall behind her. She leaned into Thirteen, their bodies impossibly close, moulding into each other. Cameron kissed Thirteen again, just as hard, her hands gliding up Thirteen's arms and running her fingers over her wrists, before sliding down to her waist and pulling her body closer.

Cameron drew back from the kiss, looking at Thirteen's lust-filled eyes. "God, do you know how much I wanted to fuck you all night?"

Thirteen's expression was a mixture of serious and teasing. "Definitely less than I've been wanting you to fuck me all night."

Cameron smiled, her eyes heavy and full of desire.

Thirteen kissed Cameron again, her hands resuming their dance along Cameron's hipbones. She eased her top upwards, sliding it over Cameron's stomach as she gazed at her body, over her head and threw it on the floor, forgotten. Her hands roamed over Cameron's skin, leaving trails of fire in their wake.

Cameron slid her hands down from Thirteen's face, over the pulse point on her neck, stopping just above her breasts to unbutton her shirt. Her hands were clumsy, trembling with adrenaline and anxiety. She slipped Thirteen's shirt down her arms, touching her everywhere in her desperation to cover every part of her, to learn every bit of her by heart.

Cameron kissed her again, as they stumbled and half fell into her bedroom, trapping Thirteen under her on the bed. They both felt a rush of electricity as silken skin met silken skin, hands hurrying to undo bra straps. Neither of them were sure who moaned first, or whether they both had. Cameron felt her skirt being unzipped, and pushed it down so that she was just in her black lacy underwear. She knew she'd never been as wet as this in her life, and she could feel hot liquid seeping from her as she kissed Thirteen's neck and then her collarbone. Her lips felt swollen as she placed a trail of breathy kisses over Thirteen's breasts, encircling her nipples with her lips, feeling Thirteen's chest rise and fall deeply with her rapid, shallow breathing. She traced the line down her stomach, lower and lower, placing a kiss on the inside of each hip, before slowly unzipping the black jeans, and pulling them off, along with her underwear.

She looked up at Thirteen as she slowly spread her legs, gliding her fingers up the soft skin of her thighs, higher and higher until Thirteen was aching for her touch. Cameron placed a soft kiss on Thirteen's core, sliding up her body and pinning her down, kissing her again, their skin both so hot and close that she wasn't sure where she began and Thirteen ended. She spread her legs to straddle Thirteen, and moaned in surprise as she felt Thirteen turn her over on the bed, switching their places. Kissing Cameron's breasts and stomach, she pulled her underwear down slowly, her eyes meeting Cameron's. Kissing up her legs, she placed a kiss on Cameron's thigh teasingly, before softly kissing her wet velvet folds. She could feel Cameron arch and gasp at her touch, at her skilful tongue as she licked her clit; Cameron's hands gripping her shoulder as she sighed in pleasure.

She drew her body up along Cameron's, feeling her warmth, her heat beneath her, wanting to make her fall apart with ecstasy. They kissed again, the heat never fading for a moment. She positioned her leg in between Cameron's, and slowly moved into Cameron, feeling her slickness, her want for her, her hipbone stimulating Cameron in just the right place.

"Fuck. . ." Cameron moaned, moving her hip into Thirteen's centre.

"You can say that again." Thirteen gasped.

Thirteen paused for a second, her eyes looking deep into Cameron's, questioning.

And all she saw there was a desire, a trust, an unquestioning honesty that filled her with such tenderness that she could barely look at Cameron, but couldn't draw her eyes away. She skimmed her hands along Cameron's burning skin, descending, before slowly circling her clit and pushing two fingers into her velvet core. Cameron groaned, arching her back into Thirteen, her eyes wide and dark. Thirteen slid her fingers deep into her body, again and again, her palm teasing Cameron's clit, her leg moving and thrusting with her hand, further and further into Cameron.

Cameron was speechless, her nails digging into Thirteen's back as she moved against her, her hips gyrating against Thirteen's as she felt the heat build up inside of her. She reached between them, lower and lower until she could feel Thirteen, and slid two of her own fingers into her, deeper and deeper with each thrust, her own desire increasing as she felt Thirteen moan onto her skin and her lust-filled eyes gaze into hers. She ran her thumb over Thirteen's clit, and kissed her. They could both feel electricity coursing through them, both gasping into each other as they were finally overtaken by the sweet release of their orgasm, their eyes holding on to each other's until they were left breathless, kissing each other tenderly and panting for air.

Thirteen lay down beside Cameron, her arms encircling her and holding her, still breathless.

"I can't believe I nearly let you go." she said, stroking Cameron's arm lightly.

"Neither can I." Cameron said as she turned and kissed her, and tucked a strand of hair behind her ear.

Okay, that was fun. I hope you enjoyed it ;) in more ways than one.
