Kate came around a little on the Alicia Rook issue, though she still assiduously avoided fanfics that paired her with anyone and seriously considered posting a rant against Alicia Rook sex scenes in the tumblr she’d created to rec particularly good Nilla fanfics. It was funny. She’d held back on the Nikki Heat novels because of how long it took her to get through them when police work took up so much of her time, but with the bite-sized fanfics that she could finish in an hour at most, she ended up reading more than she would with a paperback.
Kate and Alexis grew closer in the following months as well. Almost once a week, Kate and Alexis would Skype together to discuss the happenings in fandom and collaborate on Alexis’s dissertation. As well-mannered as Nikki Heat fandom was, it could be as contentious as any gathering of passionate people. Especially when a preview of the next Richard Castle book was released, and it appeared Nikki was being tempted to cheat on Bella with a male suitor.
That was when Kate started lying to Alexis.
She lied to herself as well. She told herself Alex didn’t want to know the specifics of her foray into fandom. That this was something special to Alex, and that if Kate shared the depth of her own involvement with Alexis, then the young woman would no longer have so much fun showing off and detailing the wild world of fandom to her clueless friend. And so Kate plead ignorance when Alexis told her what was going on, who was writing what, what ships were at war with which ships. She pretended the jargon Alex fluently spoke to impress had not become a second language.
One week, Alexis mentioned that her spring break would unfortunately overlap with her father going on a book tour. For once, she wouldn’t be able to spend her holiday with him.
All Kate had to do was float the possibility of Alexis crashing at her place and the plane ticket was bought. Kate got a nice, warm vibe off Alexis coming to meet her. She didn’t miss Castle, not really, but life wasn’t quite as fun without him there to drag her into this misadventure or that. Investigations seemed so much more ordinary, somehow. She wanted someone to get excited for her, and Alexis—Alexis called her from the plane just to chat.
Unfortunately, an interrogation ran long—Kate had to sweat the perp for four hours before he gave them anything, so there was no way to pick Alexis up from the airport. All she could do was send an apologetic text, promise to pay for the taxi, and tell Alex about the key under the welcome mat. She’d never hear the end of that.
Finally, she got loose from writing up the entire sordid investigation, handed it off to Ryan and Esposito, and drove home. Already tempting herself with the thought of a hot bath and a pint of ice cream that would not count at all if she split it with Alex, she swept through her front door, shrugged off her leather jacket, and collapsed into the nearest chair. Her collapse-chair.
She needed to find a new line of work. Maybe mall security was hiring.
Where was Alexis anyway? There were her bags by the door, but the redhead herself was gone. That was odd. Hadn’t she heard Kate come in? Kicking off her shoes, Kate pulled herself up and walked through the apartment. No Alexis in the living room, the kitchen, the guest room, the bathroom. Finally, the only thing left was the bedroom. Seemed an odd place for Alex to put herself. Kate pushed open the door and the first thing she saw was the dildo on the bed.
Then the open laptop.
Then Alexis.
“I’m sorry,” Alexis said in a paralyzed monotone, “I was just moving my things into the guest room, and I opened up a drawer, and—I thought you’d want it back. So I went into your room, and there was your laptop and you looked at mine, so I just wanted to check yours and you, uh… I didn’t know you wrote Nilla.”
Kate was frozen just as solid. “I thought I’d try my hand at it. Seemed funny. Like someone would attack me for not getting Nikki Heat and then I am… Nikki Heat. But people liked it. So I wrote another. And people liked that…”
“You read Alicia Rook stories.”
Kate blinked. It seemed rare. “Yes.”
“You wrote Alicia Rook stories. You started a separate account I didn’t know about and you used it for Alicia Rook stories. Where she’s… where Nikki and Bella and her…”
“I didn’t want you to know because I didn’t want you to take it the wrong way,” Kate insisted. “I didn’t like feeling like a tightass, so I read a few, just to give them a chance. And I saw how powerful a fantasy it was. I remembered being young—falling for older women—nothing happened, but if it had, I would’ve wanted it to be like that. And the more… honest I was about my fantasies, the more I had to write.”
“Alicia Rook with a dildo up her ass,” Alexis breathed. “That’s what you fantasize about?”
“It’s not you—“
“I thought—“ Alexis’s voice was hoarse. “That you hated it. You said it was shameful and degrading and perverted.”
“I didn’t know—“
“The notion of me having sex, the thought of someone fucking me, it was so far from your mind that you thought only a pervert could think that—“
“You’re not Alicia Rook.”

“To you I am!” Alexis grabbed the dildo and stood, brandishing it like a weapon. “You don’t write her like anyone else. You write her like me. She talks like me, she looks like me—does she fuck like me?”
Kate’s jaw twitched. “It’s just a fantasy. You said it yourself, it’s just a fantasy.”
“Is that what the dildo’s for? Reality? Verisimilitude? Do you get your ideas for fucking little Alicia Rook while you have that in your cunt?” Alexis’s eyes burned. “Or in your ass?”
Kate let her lips purse, once, before she set them. “Are you going to stand there and pretend those stories you were looking up were research?” Her eyes flickered to the dildo. “Or that you don’t have something just like that back in your dorm? Don’t act so surprised, Castle.”
Alexis shook her head. “It doesn’t surprise me that you have a dildo. What surprises me is it being a double-header. Do you fuck other women, Kate? Are they young? Are they ginger? Do you pretend they’re me?”
There was only so much red you could wave in front of a bull before the bull saw it. In one charge, Kate was in Alexis’s face. “No. When I put that thing in my cunt, I pretend it’s you fucking me. And I come like a bomb going off.”
They could’ve kissed. They didn’t. Kate shoved Alexis down on the bed and the dildo slipped from her fingers and her skirt flew up her legs and her breasts bounced inside their bra. It turned Kate on so hard that her breath left her. She didn’t breathe as she dropped over Alexis, mounting her on the bed. Alex, on the other hand, couldn’t be breathing harder as Kate’s eyes swam up her body.
“Wanna see more?” she asked, suddenly as eager as a puppy dog shown a new toy.
Kate nodded, her teeth grinding together.
“Like my pussy? Would that do?” Alexis wound her panties down her thighs, the shadow of her lifted skirt barely censoring her. Kate could’ve drooled at even the obscuring of that sweet mound—the soft slope sheathed in flaxen pubic hair, the indentation of her labia more like an invitation than a part of her body. Kate reached out to touch, to have…
Alexis rolled away, laughing now at the root of the bed. “Or do you wanna see my boooobs?” She drew the word out self-deprecatingly, laughed as she pulled her blouse over her head and snapped off her bra as she lowered her hands. Her breasts were small, but went with the rest of her body. There didn’t seem to be an ounce of excess anywhere on her. She’d become a sort of ascetic in reaction to her father’s libertine ways. Beckett felt a fierce kinship with her.
She covered it with a taunt and a closing of her arms over her chest. “Alright if I touch you now, or would you like me to stare at your ass too?”
“Actually—“ Alexis smoothed her skirt over her pantyless crotch. “I’d like to see what you’ve got, Detective Beckett.”
Kate gave some thought to giving Alexis a show, doing a little dance, but a girl didn’t get a crush on a policewoman hoping she’d turn into a stripper. She undressed curtly, efficiently, and stood over Alexis with her hands on her hips and her scowl distinctly unimpressed, the picture of a butch power dome.
“Fuck, you have great tits,” Alexis burst out, seeing Kate naked.
Kate gave her hips a swing as she took one last step toward the bed. “How can you say that when you haven’t even felt them?”
For a moment, Alex was gobsmacked. Then she threw her hands onto Kate’s breasts like suction cups, squeezing them, pushing them together, then burying her face in them, howling into Kate’s cleavage like a Beatles fan. Kate didn’t mind. She wound her arms around Alex, snaking her fingers down to squeeze Alexis’s buttocks. When Alex hummed appreciatively, Kate went further. As Alex kissed the very breasts she was kneading in her hands, Kate felt between her cheeks to the creamy little slit of her sex.
Alexis gasped explosively, turning Kate’s cleavage into an echo chamber. Now unable even to beg for Kate’s attentions, she threw herself back onto the mattress, pulling Kate with her so they landed in each other’s arms, her small breasts against Kate’s larger ones, her petite body against Kate’s taller, stronger form. The only thing they seemed to have in common was below the waist. Both their pussies were wet as they rubbed together.
“Oh shit! That feels so good!” Alexis huffed out, her face already turning pink as she desperately ground herself up against Kate, her legs wide open and receptive.
“That it does,” Kate said coolly, enjoying Alex’s spirited but unskilled efforts while not finding it quite the revelation that her younger lover did.
“Don’t stop! Don’t move!” Alexis’s whole body was flying up to rebound off Kate. Her eyes squeezed tightly shut. “I think I’m gonna, gonna, GONNA—“
Alexis’s pussy was on fire, sensitive to every shaft of light, every mote of dust, every particle of air. Every curve of Kate’s body pressed against her own. She breathed hard and fast and erratic as she clung to Kate’s body, an engine trying to turn over. Kate kissed her and something inside her caught, clenched, turned into a breathy string of ‘oh’s that bubbled up from her straining throat.
When Alexis went limp, Kate took the opportunity to give her a long, proper kiss. One that lasted almost two minutes, the girl just lying under her and giving into Kate’s slow lovemaking. Then Kate rolled off her. The detective had to remind herself that Alexis had gotten swept up in this, might be feeling pressured, uncertain. Kate would give her a minute to regroup. Then she’d fuck her brains out.
“You came, right?” Kate asked, intentionally trying to seem blasé. The casualness of the question helped make it a lot easier to answer for the virginal Alex.
“Yeah,” Alexis blushed. The extent of her arousal—how her body had just keened to Kate, exploded from touching her like a stick of dynamite thrown into a fire—it embarrassed her. She had never come so fast before, but at the same time, she had never come so fast. Alex didn’t know how to feel about it.
“First time with someone else?”
Alex nodded briskly. “Sometimes, I felt myself get close, when I was making out with one of my boyfriends, but it never—“
“Alexis, are you a virgin?”
Alex almost rolled away from Kate, but the motion arrested itself so she just looked away, like she was getting comfortable. “Maybe…?”
“Do you want to be?”
All Kate could see was the back of Alexis’s head. Her strawberry hair stirred with the air conditioner coming on.
Kate reached down and touched Alex’s thigh. It was soft and warm, the dewy hairs there making it seem far more delicate than it was. “Alex…”
“How would you do it?” Alexis asked, the muscles in her leg twitching, turning, spreading just one degree.
“I wouldn’t use fingers or tongues. I’ve read your stories. I know that’s not what you want.” Kate reached over to the dildo, still lying on the bed, barely moved. It had rings for a harness that she kept in her nightstand. It could be worn so some of the dildo went into one woman and the rest went into the other. “I’ll use this.”
Alexis was silent.
“Did you think about that, when you found it? When you picked it up? Did you picture me using it on someone? On you?”
Alexis turned to her, hair exploding with the sudden motion. “Do it.”
Kate gave her a brief kiss, one meant to be over quickly. She didn’t want to come off as patronizing. Then she opened up the drawer, finding the elastic belts in the miasma of condoms and old paperbacks and one surprisingly tiny vibrator. She clipped them onto the dildo and rolled the belts up her legs like stockings, fastening them at her hips. Alexis watched closely, chewing on a fingernail, her jaw dropping when Kate sunk four inches of the dildo into herself without a care. Tightened the belts. The rest of the dildo, maybe six inches, maybe seven, Kate intended for Alexis.
“It’s gonna hurt,” Alexis said with strained calm, smart enough not to make it a question.
“Yes. But I’ll be careful. I’ll only let it hurt a little, at the beginning. Then it’ll start to feel better. I won’t have to be as careful. I’ll make it feel nicer and nicer until… well. You’ve read the PWPs.” Kate reached into the nightstand again, finding a half-empty tube of lubricant and using it up. First slickening her dildo from hilt to tip, then massaging it into Alexis.
The redhead jumped when Kate started to touch her, but she smiled when she realized they hadn’t quite started yet. She was plainly apprehensive. While still not wanting to coddle her, Kate kissed her reassuringly. Alexis was quicker to respond to her fingers with a tongue in her mouth.
“Put it in,” Alexis gasped hollowly when Kate moved on to kissing her neck. “Put it in, put it in, put it in—“
Kate took Alex’s hand as she continued kissing her, interlacing their fingers, squeezing it warmly. Letting Alex feel warmth and pressure for just a moment before the butch act had to keep going. Then she brought Alex’s hand down to the dildo jutting from her groin.
Alexis had chosen well. Maybe it was her plan. Though long, the model was relatively slender and very smooth, with none of the accoutrements that might be difficult for Kate to explain. Kate let Alexis feel its weight, its heft, how slippery it was with lubricant. She encouraged Alex to jack her fingers over its length, shifting it minutely inside the detective. It felt nice. If Kate were looking for nice, she would’ve been very satisfied.
Instead, Kate stopped simply rubbing the lube into Alexis’s genitals. She penetrated Alex, one finger, then two in rapid succession. She was easily able to find the small patch of texture that indicated the G-spot, and her other hand found Alex’s clit even easier. She rubbed Alex inside and out.
Alex seemed to have a seizure. She keened and thrashed, crying out continuously as her hand flew over Kate’s artificial strap-on. By the time Kate judged her significantly undone, relaxed and loosened, Alexis was melting in depletion.
Kate got up from the bed, leaving Alexis lying there with eyes closed and breaths coming deep. She stood over Alex. She waited for her to come to. The dildo hung from her, an artificial cock with a permanent erection. Kate squeezed the dregs out of the tube of lubricant and spread it lovingly over her cock. It was time.
Alexis opened her eyes, focusing on the dildo with preternatural interest. “It looks so big…”
“It’s not,” Kate assures her. “Not compared to you. When you’re aroused, the way you are, you can take a lot more than you’d think. I’ll go in nice and easy. I’ll play with you while I’m doing it. It’s going to feel wonderful. You’ll see.”
Kate lowered herself onto Alexis with a deep kiss, her slick cock rubbing against Alex’s freckled thigh. Kate whispered reassurances with her kisses and strokes of Alexis’s ripe body. “You’ll see… you’ll see…”
Alex put her arms around Kate, fisting her hands in Kate’s hair. “Show me.”
Kate reached down, letting her fingers flow over Alexis’s body as they went, before gripping the narrow head of the dildo. She put it to Alex’s opening, felt Alexis’s hips flinch in response. Kate gave her another comforting kiss. Then she pushed.
“How’s it feel?” she asked, feeling Alex’s body start to resist her.
“Funny…” Alexis trailed off. “But not bad,” she added.
Kate pushed a little harder, trying to lodge the cockhead inside Alex without hurting her too much.
Alexis’s lips were pinched together.
“Does it hurt now?” Kate asked.
Alexis nodded.
“It has to, baby. I’m sorry.” One more kiss of Alex’s lips, like Kate was snatching more and more candy from a dish. “Just relax… relax… It’s me. I’m not going to hurt you. You know I won’t hurt you…”
Tears turned Alex’s bright blue eyes liquid, but she nodded, frantically believing in Kate.
“I’m going inside you now, Alex. It’ll hurt for a moment, but then it’ll feel so good. You’re love having me in you.”
Kate kissed Alexis as she took her virginity.
Alex tore her mouth away, howling, trying to squirm away from her impalement. She hadn’t been ready—she just hadn’t been ready for how it would hurt and how good it would feel, all at once, the skill Kate had plied her with to turn some of her pain into pleasure. Yet she could feel the trickle of blood between her thighs, knew how irrevocable this was. Guilt sprung up in her: how she had jumped Kate, how she hadn’t even dated her, didn’t know her favorite food, that this woman could’ve been her stepmother in another life. And none of that mattered. The pain faded. The pleasure continued to grow.
Kate held Alexis as she sobbed, a few fat tears squeezed from her tightly closed eyes. She kissed the girl gently, petted her body, but did not move the dildo an inch. The territory it had won was hers. On some primal level, Kate could not consider relinquishing it. She was as aroused as Alexis—it felt to her like she actually was inside the redhead, feeling the warmth of Alex’s needing hold on her. It was shockingly arousing.
They were connected now, body to body, pleasure to pleasure. Both women looked down in wonder at their sex, breached by the end of the dildo whose shaft led inevitably to another woman’s pussy, stretched in exactly the same manner.
“Is it okay?” Kate asked, her own breath a little short as she gave Alexis one more kiss. “Is it okay?”
“Yes. Yes, please. It’s okay. Please.”
And Kate moved her hips in a slow circle, twisting the dildo inside Alexis like a living thing. Alexis’s mouth opened in a long, silent moan, her jaw wobbling, her tongue unfurling, but nothing coming out. She trembled, and it became spasms as Kate rotated herself again, the dildo pressing where no fingers had ever been. And Alex’s enjoyment, her vibrations, coursed through the silicone toy that joined them and tickled inside Kate like the tongue of a small kiss.
Soon they were both grinding away at each other, fucking only as hard as they took what they were given. The dildo slammed into Alexis, into Kate, into Alexis, as the detective loosened the straps holding it in place to let the girl fuck her. Their bodies met: lips, breasts, bellies, and finally groins, the shaft buried between the wet lips of their touching cunts.
They never stopped, never slowed. Alex kissed her mentor repeatedly, as if giving a recitation she hoped would meet with approval, and Kate flagrantly gave it. Their hands traveled each other’s bodies, but finally settled on their lover’s waists, to keep each other close and pull them closer. Kate laughed as her ample breasts swamped Alex’s, feeling the girl’s nipples prick her flesh deliciously. She kissed Alex even more, wishing she had eaten the girl out before so she could taste her own deliciousness on Kate’s tongue. And she tried to ignore the mounting pressure in her groin, the impending orgasm that she wouldn’t let have her before she gave Alexis her due.
Their pussies sealed together, impaled on the same spike, fueling the wildness above them even as the reaming of almost a foot of hardened dildo proved secondary to the soul kissing embrace that consumed the two women.
Alexis came repeatedly, her breath pounding against Kate’s clavicle as the older woman guided her through each orgasm. They still hurt, at first, a bittersweetness that compared unfavorably to Alexis’s masturbation. But the pain dwindled to nothing under Kate’s steady attentions, kissing Alexis, stroking her, her touches half soothing and half groping. Finally Alexis felt nothing, absolutely nothing but pleasure and she was screaming into Kate’s flesh and when she was at all conscious of her situation, her only thought was to share her ecstasy with her lover.
Her hand skirted Kate’s back, found the buoyant ass she had already cupped so many times. But now, fingers wet with the lube that was by now smeared everywhere, she dug her finger into Kate’s ass.
For Kate, her sudden orgasm felt like some great and terrible creature had surfaced within her, a monster of an climax, ravenous and catastrophically destructive. Her body—all her sensations, her emotions, her sight and hearing and touch, they were all crushed into her cunt as it clenched down on the dildo Alexis was stabbing into it. And Kate could’ve sworn she felt it give.
Eternal minutes later, she opened her tightly clenched eyes to see Alexis under her, panting with the strains of her own finish. Kate watched her closely as she drew the dildo out a little at a time; a few inches from herself, then a few inches from Alex. The girl was wracked with delight, but far too satisfied and comfortable for another go. Kate could sympathize. She dropped down beside Alexis, the dildo between them, its entire length proudly wet.
“Not bad for a first-timer,” Kate drawled. “You might just have a future in this.”
Alexis giggled, unable to keep up Kate’s pretense. Then she calmed. “Was it okay—with my finger?”
“Oh, yeah. A little warning next time, but… better than I would’ve expected.”
“So you really haven’t done it before? In your butt?”
Kate rolled her eyes. “It hasn’t really come up. Who do you think I date, anyway?”
Alexis shrugged helplessly. “Me?”
Kate levered herself up to her feet, granting Alex a display of what had to be the finest ass in the Five Boroughs. “I’m getting us some wine. You should have wine when you lose your virginity. It’s a rule.”
Alexis lifted her head to watch Kate’s passage into the next room, then dropped it back down to the tangled sheets under her. “Okay.”
Kate was trying to play it off like she’d merely tolerated having her backdoor opened, but Alex hadn’t been too far gone not to see how she’d come like a wild woman with her ass fingered. And though Alex was no Heatmiserx93, she’d written a few fics, just so her encyclopedic knowledge of the real Nikki Heat didn’t go to waste.
And seeing Kate’s reaction, along with the look of some of her other dildos, Alex had an idea for a great story.
