"Hey, birthday boy." There was no need for me to speak quietly as it was still quite early in the morning, but my default voice was still at a soft volume.
Spencer looked up from the crossword puzzle he had been solving like a race with a soft smile directed at me. He definitely did help me come out of my comfort zone a lot, but whenever he looked at me with softness as if he was adoring me I couldn't help but feel a bit of shyness bubbling up.
I was painfully shy around almost everyone in my life, except Spencer. When I had joined as an assistant technical analyst for Garcia I was in stark contrast to her bright and bubbly demeanor. For a long time I didn't connect with anyone on the team, just did my job as was described to me and only spoke when I needed to.
The event that had gotten me to come out of my shell a little happened to be when I was reading a book that Spencer had loved. He launched into a full rant about the book that I had barely even started immediately when he saw the cover. When he had realized he'd spoiled the book he had apologized profusely. In a rare moment of bravery I told him he could take me to a bookstore and buy me another book as repayment, albeit with my head hanging low speaking so softly that Spencer had to ask me to repeat myself 3 times. Though, it was really just an excuse to get him to talk again, I loved listening to him talk. Ever since then we had been joined at the hip, even beginning to date two years ago. I often helped him become more grounded in the world he often said and it was quite obvious to everyone around me that Spencer helped my confidence bloom.
I will admit he could be a little possessive as of late though not in a bad way, especially after coming back from prison. But, I was still extremely surprised when he came up behind me subtly in the room while I was making the first cup of coffee for the both of us in the morning and I felt a tap on my ass. He must have finished his crossword puzzle.
I yelped quietly in surprise, it didn't hurt, it had just been unexpected. I turned to face him with a bemused look on my face quirking my eyebrows up shyly in question. My shy befuddled look was in stark contrast to his smirking face making me peek up and smile a little. At least no one had been around, Spencer was brave just not that brave.
I wasn't sure what made me a little bit more bold today, maybe I thought I'd get some leeway for brattiness because it was his birthday. Honestly, I don't know why I thought I could get away with it, it was his birthday after all, not mine. I still decided to push up my glasses a little before speaking smoothly with a little more confidence than normal,
"Isn't it the tradition that the birthday boy is the one that's supposed to get the spankings?" Spencer's face was one of shock at first, not used to a snap back from me. Once he recovered from my unexpected remark a dark look that I almost never saw directed at me came over his face letting me know without any words that I was in for it tonight. I wasn't going to get my normal soft but dominant boyfriend tonight.
Spencer then confirmed my thoughts when he leaned in closer behind me slightly pushing me into the counter and then whispering into my ear, " I hope you know what you just got yourself into, Doll."
His presence then left me to go back to his desk, making sure to grab his sweetened coffee I had been making for him along with mine. Making sure he did make sure to spank my ass one last time, this time much harder than the first. Yeah, I was definitely in for it tonight.
I looked around to make sure that no one had been looking towards the break room, luckily no one had been. My cheeks were hot with residual embarrassment and my heart still pumping loudly with adrenaline from getting the courage to say a sassy sentence to Spencer. I tried to mask my embarrassment by bringing up my own coffee to hide my face which also fogged up my glasses a little. I will admit that the rush I felt when I had finally gained the courage to sass back to Spencer made any punishment I was going to get tonight worth it. I even was slightly looking forward to the birthday spankings I was definitely going to be getting.

When work came to a close I was soaked through my panties already in anticipation. Spencer had been casting me looks throughout the rest of the day, it had made me so desperate I had wished I had gotten the courage to make a snarky comment later in the day so I wouldn't have had to wait for some relief. Though, to be honest I was partially anticipating not being able to have any relief at all tonight by the way Spencer had been looking at me. Even when everyone had been singing happy birthday he had been looking at me as if he was deciding how he was going to take me apart later.
When I got the text at the end of the day that he wanted me to come to his apartment I felt myself get increasingly flustered. I knew I should've just stayed in my lane as a good girl who did everything for her dom. My flustered state was so noticeable that the rest of my co-workers had even noticed, which was telling considering my normally shy demeanor translated to flustered.
As soon as I shakily opened the door with the spare key Spencer had given to me on our last anniversary I was greeted with the tall imposing figure of him standing at the end of the entryway.
His slow walk over to me caused me to drop my purse over being intimidated, it was a good thing though because I was positive I had never been so soaked before.
Once he reached me he tilted up my chin with one finger and spoke with a calmness as cool as steel, "You're going to do as I say tonight, I'm going to punish you. If you speak out of turn once I won't let you cum for a week."
Your confidence in your bratty behavior from early had all but completely deflated at those words. He had edged me before too and I had done it many times before, never for so long though. I definitely knew I wouldn't be able to handle it.
"Yes, Sir." I spoke firmly to emphasize that I wasn't playing around anymore, I was ready to listen like I normally did.
"Just a few simple words and you're so easy to tame?" You nodded with a whimper and averted your eyes away, embarrassed with how quickly he could bring you back to your usual behavior. He reached forward to push up your glasses that had slipped down your nose a little which also refocused your gaze back on him before he spoke again, "I knew you'd be so easy, you're always so desperate to please me and- yourself. I knew as soon as I threatened to take it all away you'd come crawling back doll. "
He enveloped me into a harsh all consuming kiss that there was no escape from, not that I wanted to though. He easily dominanted the kiss while also running his large hands through my hair and tugging harshly to pull me closer. Suddenly he broke the kiss, leaving us both panting and he touched me jaw again. This time he gripped it hard before giving me another command that I was ready and willing to follow,
"I want you to ride me tonight, it is my birthday after all. I want you above me while I look at you fucking yourself on my cock, just desperate to cum while you service me." I whined at his words, hoping that I'd get to cum. But, I had never really been bratty, the only spankings I had gotten before this was because I asked for it. I whimpered in wonder about whether or not Spencer was going to give me the chance to cum or not. Spencer seemed to understand my nonsensical plea then speaking with a condescending tone, "Oh no, you're not going to get to cum tonight until I see if you regret your bratty behavior, little doll."
He hauled me up onto his lap after basically ripping down my panties and skirt to straddle him when he sat down onto the couch, which happened to be the closest surface suitable for what Spencer wanted to do to me right then and right now.
He ran his fingers through my folds collecting my juices, teasingly rubbing my clit for a second of relief before popping his fingers into his mouth to get a taste. "Mmm, you taste wonderful. Want to taste?"
"Y-yes, Sir." He already knew my answer though considering he had already pulled my hair to tilt my jaw back causing me to stutter while running his hands through my folds again. Once he got his finger sufficiently wet again he shoved his fingers into my mouth with no warning, gagging a little in response. He pumped his fingers in and out of my mouth until he was completely satisfied how I had sucked the juices off of his fingers, until drool had been escaping the corners of your mouth.
Again he rubbed my clit in a teasing manner before speaking, "You're already so wet you're practically dripping, I could just slide right in."
It wasn't too long until he had and he was right he did slide right in, my walls gripping him like a glove.
I was only allowed a moment to adjust before he prompted me to start moving by saying, "I'd like my birthday present now."
I began to bounce on top of him as I had done many times before. At one point I had tried to take my glasses off to make myself perhaps more comfortable but was met with a light growl telling me that he wanted them to stay on. After a while I had created a rhythm for long enough that I was wondering when my punishment was going to come, I already had a pretty good idea what it was going to be.
A harsh sound cracked through the room suddenly confirming my suspicion, he had spanked me hard. My hips stuttered from shock, then stopping completely reeling from the harsh slap.
"Call them out, Doll." He sharply spoke after landing the second blow onto my other cheek.
"2-2!"
"I'll let that one slide but call them out clearly next time."
My hips were burning as I tried to focus on rotating them properly while he started to lay in on my ass. It also was difficult to focus on making sure I was calling out the spanks with some semblance of clarity.
"12!" "13!" "14!"
Number 14 had been the harshest one yet making me cry out so loud in the back of my mind I was concerned that maybe his neighbors would call the cops. Though the burning pleasure echoing through me wasn't letting me voice my concern to Spencer, all I cared about was trying to hold off my orgasm that I was already dangerously close too despite being so far off from the finishing number.
When tears started to prickle in my eyes Spencer looked up at me with slight worry, breaking the scene a little. I hadn't gotten near my breaking point yet so I nodded for him to continue, I only had about 10 more to go.
"24! 25! 26!"
When my hips started to slow down slightly because of the stinging pain from his spanks he gripped my hips hard which I was sure would leave another kind of mark that I'd wear for a while.
He released his hard grip with one hand to continue the count to the magic number, how many years old he was today. I willed myself to continue counting because I knew I'd just get myself signed up for more, maybe even starting back from zero— I didn't know if I could handle that and successfully hold off my orgasm.
"36!"
"37!"
"38!" The last stinging slap cracked down like a whip to my ass that was no doubt probably would make it hard to sit for the next week, hopefully not more.
I was hoping to get relief from Spencer by letting me have permission to cum but, when he asked the next question I realized he wouldn't let me off so easy, "Do you think you've earned it?"
"No, sir I haven't but I'd really like to cum please?!" I knew I hadn't begged enough in his eyes, I knew I hadn't earned it yet, but I was just so desperate to finish. His cock was running up perfectly against my g spot hurtling me precariously close to the edge.
"Say your sorry."
"I- I'm sorry, S-sir!" I stuttered out in desperation which was usually not something Spencer would have tolerated, I think he sensed that I wasn't going to last any longer with the edging and being no longer physically able to control it.
"Ok, fine Doll I guess you can cum." As soon as 'fine' had left his lips I stopped holding my orgasm back out of pure exhaustion. It was so devastatingly good, ripping through every nerve in my body, that I barely noticed Spencer finishing as well. I only felt the last few ropes being pumped into me after the majority of my orgasm had passed.
Our panting breaths mingled as I meant over to kiss him while I rocked my hips to drag out the last dregs of our orgasms. The kiss ended up being more messy than I intended but I was just desperate to feel his lips on mine again.
Spencer gripped my lightly  jaw once he had caught his breath some and turned my head to the side to press a kiss below my ear before speaking softly, "Such a good girl."
"Thank you, sir." I whispered back with another characteristic whine from me that was a little pathetic on my part, I had been ruined by him for sure.
We basked in the presence of each other for a little while, just enjoying being tangled all together. Though after a while the stickiness between my thighs got a little too uncomfortable and Spencer started the main part of aftercare for me. He seemed a little caught up in his thoughts while he started to clean me up so I prompted him with a little boop on the nose to silently ask what's wrong.
"Did I go too far?" The worry he felt was evident by the tensing in his shoulders where he often seemed to hold his worry.
You quickly interjected as he began to stutter out the beginnings of an apology despite not letting you answer yet, "If you had, I would've used my safe word."
He breathed out a sigh of relief as he resumed my aftercare, making sure I was well taken care of and pampered to perfection. We were sitting in a bubble bath when I finally realized something, I hadn't said Happy Birthday to him yet.
"Happy Birthday, Spencer."
I said while I was straddling him and I could already feeling him getting ready for another round, though this one would surely be gentler than the last as to not irritate my ass anymore. Despite my still stinging backside I was glad I stole Spencer's birthday spankings.
