It had taken Alex quite some time to put two and two together.
She'd always been extremely vigilant about tracking her cycle, which is how she'd first noticed the pattern. Namely, the way Emily always seemed to have a voracious sexual appetite whenever Alex ovulated. And it also happened to be the time she was most likely to bring out the biggest strap on they owned.
She didn't know for sure until...
Emily was staring intently at her laptop, doing her best to finish up the latest case report (on top of the eighteen or so others sitting on her desk in the bullpen for tomorrow). She knew that if she didn't finish it now, she would have Strauss breathing down her neck.
The only problem preventing her from being productive, though, was Alex...who was being completely distracting as she squirmed in her lap, warming her cock. She was making the most delicious sounds of impatience and need, even as she tried to stifle them with her face buried in the crook of Emily's neck.
"Daddy," she whined, doing her best to look adorable as she pouted. "You're taking way too long to finish."
Emily chuckled. "Finish the report or finish you?" she asked with a Cheshire Cat grin. She knew that the longer she made Alex wait, the harder and faster she'd cum...and she had made it her mission to achieve a personal best every single time she fucked her.
Alex cocked her head, pouted.
"You know Daddy's busy," Emily scolded. "I told you you weren't allowed to sit here unless you could be a good girl."
She whined, sighed dramatically, still rocking her hips slightly. Then, she leaned in so she could whisper in Emily's ear, "But Daddy...I want you to put a baby in me."
Immediately, Emily stiffened below her. "What?" she said breathlessly.
"That's what you want, isn't it?" Alex asked, "You want to knock me up so the whole world can see that I'm yours."
For a split second, Emily didn't react and Alex feared she'd pushed too far...then, Emily chuckled heartily. "Is this what's turned you into such a little cockslut today?"
Alex opened her mouth as if to argue, but Emily didn't give her the chance, her thumb finding her clit and quite effectively turning off her brain.
"You've discovered Daddy's little secret and it turns you on, doesn't it? You'd love to walk around knowing the whole world sees that you let me cum inside you...that I fucked a baby into you," Emily taunted her. "Isn't that right?"
She let out a needy little whine when Emily stopped working her clit. "Daddy..."
"What is it, Angel? You can tell Daddy." When she whimpered again, Emily slapped her thigh. "Use your words or you get nothing."
"I want your cum, Daddy!" she begged, squirming in Emily's grasp in search of any friction at all. She hadn't realized quite how much the idea excited her until Emily had started talking about it, something animalistic inside her awakening.
Emily's responding smirk was so damn smug that Alex wanted to be annoyed, but it was a difficult emotion to achieve when Emily had ducked her head to suck a bruise to the top of her breast, her hands still holding her firmly in place.
Once she was satisfied with the mark she'd made, Emily pulled back to examine her handiwork, pleased to see the way her chest was flushed and heaving already. She knew it was a sure sign that Alex was barely clinging to her self-control. "You gonna be a good little cumslut for Daddy?"
Alex nodded eagerly, clearly hoping Emily might take pity on her obvious state of need.
Still grinning smugly, Emily slapped her ass sharply. "Bend over my desk, Angel," she ordered. She watched with hungry eyes as Alex was quick to obey – leaning on her desk and supporting her weight on her elbows – and she very nearly moaned aloud at the sight of Alex's cunt clenching at nothing. "Fuck, I love this pretty pussy," she husked.
She leaned forward, then, to drag her tongue through Alex's cunt.
"Daddy!" Alex cried out – not having anticipated that – making Emily chuckle. "Daddy, if you keep doing that, I'm going to cum..."
Emily smacked her ass again. "You'll wait," she scolded. And to prove her point, she spent the next several minutes lapping hungrily at her cunt until Alex was keening and trembling with the effort of keeping her orgasm at bay. "Good girl," she purred as she stood.
"Daddy, please fuck me..." Alex begged, willing to do whatever it took to be given permission to cum...and she knew how much Emily loved to hear her beg. "Fuck your cum deep inside me and knock me up."
"Jesus Christ, Alex," Emily cursed, her words driving her absolutely feral with desire. She lined her cock up with Alex's drenched pussy and pushed into her in one thrust. "I'm going to fuck you so full of my cum until it's leaking out of you. I'm going to do it again and again until your belly is swollen with my baby. Isn't that right?"
Alex moaned, tossing her head back as Emily began thrusting, her hips slamming into Alex's ass. "Fuck me, Daddy!"
Emily groaned as she fucked her, loving the way Alex was instantly reacting to her with little whimpers and moans, moving her hips in time with each of her thrusts. "I love this sweet little pussy," she purred, "So fucking tight for Daddy's cock. Who does this pussy belong to?"
"You, Daddy," she whimpered, "Just for you."
"That's right – you're my little cumslut."
Each of Emily's thrusts had Alex's hips bumping sharply into the edge of the desk, surely leaving bruises...not that Alex was complaining. In fact, she was begging for me. "More, Daddy. I need more."
Emily let out a dry laugh. "You want more, sweetheart? You want Daddy to fuck you harder?"
She whimpered, nodded. "Please?"
"Well, since you asked so nicely..." she cooed. And with that, she wound her fingers in Alex's hair for leverage as she thrust into her with renewed vigour.
The sound of Alex's whimpers and the squelching of Emily's cock moving her dripping cunt were driving Emily into a frenzy and all she could think about was fucking her seed deep into Alex's cunt. "Are you going to cum for me?" she asked, "I want to feel this sweet pussy grip my cock, milk every drop of cum from me. Doesn't that sound good, Angel?"
Alex whined, nodded. "Let me cum, Daddy... Please?"
"You can cum, sweetheart," Emily said. "Cum all over Daddy's cock." She punctuated the command by finding Alex's clit with her gun-calloused finger, rubbing it in sharp counterpoint to each thrust.
"Jesus, Emily," she keened, tossing her head back as her cunt clenched around Emily's cock with her climax. "Fuck!"
Emily kept moving inside her until Alex was begging her to stop, her cunt overstimulated nearly to the point of pain. With a firm smack to her ass, Emily squeezed the base of her cock, coating the walls of Alex's pussy in lube. "Jesus Christ, Alex... Where did that come from?" she asked with a little laugh as she pulled out.
Alex just smirked. "I believe the phrase you're looking for is: thank you." She stood, cum dripping from her to pool on the hardwood floor. She turned to kiss Emily, her teeth sinking into her bottom lip just the slightest bit, making Emily moan.
Emily's hand came up to wrap around Alex's throat, fingers tightening just the faintest bit, a gentle but unmistakable reprimand. "You've got a smart little mouth, Angel," she chided. "Now, why don't you put it to better use and clean up the mess you've made..." She gestured pointedly to her cock, leaving no room for misunderstanding what it was she wanted...
