“Good morning Jason” she grins as she is laid on my bed, propped up on her elbow.
“Bridget what the fuck are you doing in my apartment? Let alone my fucking bed!” I growl at her. I actually realise that I’m naked under the covers so pull them a little tighter around me.
“What I can’t come visit my big brother?” She says eyeing down at my crotch. My step sister has always been one for flirting all the time.
“Not when you just show up, how the hell did you even get in?” I ask.
“Well I came to your apartment but clearly you weren’t in, so I was outside about to get a taxi when I saw you with a very lovely lady. So I followed you up and slipped in behind you both. You both had eyes for each other and didn’t waste any time getting to the bedroom.” She made the action of putting her index finger through the circle of her thumb and finger.
“What the fuck?” I groan. As I fall back onto my pillow. This was way too early and my head hurt far too much to be dealing with this right now.
“So yeah I slept in the spare room, your bed is way comfier though. Shame your friend didn’t hang about. She was hot!” Bridget was right there, I do remember ... fuck I didn’t even get her name or number for that matter. Shit. I would have liked to be with her again but with less alcohol involved.
“When did she leave?” I had no idea so Bridget must have.
“Mmmm just under an hour ago I think. From what I heard last night I’m surprised she didn’t hang about for seconds. Sounds like my big bro isn’t bad in the sack. Has a natural talent in other departments too!” As she says this she tries to pry up the covers.
“Fuck off Bridget, you fucking weirdo. Get out of my room!” I scold her.
“Aww you’re no fun!” She puts on a sad frown but I know she’s not upset. I do know she’s wild. Thankfully without any further fuss she gets up and leaves my room.
I take a deep sigh as I need to pull myself together. I manage to muster the strength and energy to get myself showered and dressed. Bridget is sat on the sofa on her phone when I come through. She lets out a wolf whistle.
“Check you out all professional, damn looking good!”
I ignore her comment and go make myself a coffee, I need one, hell I need two. I pop some painkillers and take a good gulp of coffee.
“Right I’m not in the mood nor do I have the time to deal with you just now. There’s a spare key in the drawer, if you are hanging about don’t wreck the place and zero people over!”
“Booo you used to be fun.” She sticks her tongue out and gives me the thumbs down.
“You are more than welcome to leave right now?” I say sternly to her.
“No no I’ll behave.”
“Ok I’ll be home later.”
“Bye darling love you” I hear her shout as I leave my apartment and head for work.
Bridget has been a royal pain in the ass for years. She has no filter and has always been crude.
“Good morning Mr Holmes” Danielle a young attractive dark haired girl greeted me. She was a sort of P.A for me but not just me exclusively. She wasn’t available to us night and day like Mr Bowman’s PA is. Danielle is here to help myself and some of the others with some admin and clerical work.
“Good morning Danielle.” I say in a gruff voice.
“Rough night?” She asks even though she knows the answer.
“Fletchers fault.” I say as I rub my temples when I plonck down in my chair.
“Always is sir.”
“Please not with the sir, make me sound so old, I’m not a great deal older than you!” I know she did it too be professional but it wasn’t for me. Don’t get me wrong she needs to address Mr Bowman in the right manner but I don’t run the company.
“Just the thirty years ... sir!” She stifles a giggle.
“Heeeyyyy” I groan. The age gap was closer too ten years. I’m sure Danielle had not long turned nineteen.
“Apologies Mr Holmes. You only have one new message and I think you’ll be glad to hear no meetings today.” She hands me a small memo note with the message details on it.
“Thank you Danielle. Are Fletcher or Kyler in yet?”
“Mr Wood is yes, I think he had a very good night last night. He’s got a very large grin on his face that hasn’t disappeared. However there is no sign of Mr Smith just yet.” Danielle’s tone turns a bit more serious at the end.
“Mmm, he doesn’t have any meetings out of the office does he?” Normally I don’t care too much purely because he’s always in before me. Maybe got lucky like Kyler and I. On the other hand if he did, he would be in this office right now, gloating.
“No not that I know of!” Daniele says as she checks the iPad in her hand. “No he only had one scheduled for later today but that’s booked for his office.”
“Ok thanks anyway Danielle.”
“Will there be anything else?” She ask politely.
“Not just now thank you.” I smile at her as I get logged onto my computer. I deal with a few emails and other bits and bobs. Friday is usually and thankfully a quieter, slower day for the business. Which is surprising to be honest but not unwanted.
The company sort of acts as an outside man for government cases to act as an independent advisory as such. Basically we deal with a lot of the nitty gritty stuff. We deal with planning permissions or building permits, funding programs and grants, a lot of stuff really but nothing criminal related. We get paid for our services plus a bit of commission for certain things. I believe Mr Bowman’s grandfather started up the company and got his fingers into a lot of high ranking pies. Made millions if not billions over the years.
Once I’ve got up to date with my work, I go across my office to make myself a coffee. Yes I have my own little machine in the office. Trust me it’s essential at times, especially when it comes down to deadlines for deals or having to work on.
“Oh that for me? Cheers!” Fletcher says as he waltz into my office, yeah he doesn’t knock.
“No this is mine, think your office is down the other way!” Wait he’s dressed the same.
“Fletcher have you been home?”
“Ssshhhhh!!” He hisses at me as he closes the door to my office. “So as you can see, no I haven’t.” Fletcher then goes on to tell this big long extravagant story about last night. To summarise after closing, Hugo made it an open bar for him and a few girls. They all got wasted and he had a threesome with two sisters in Hugo’s apartment that he has above the new place.
“Rigghhhtt!” I say as I take a deep drink of coffee. “Gutted I missed that.” I pretend, so it makes him feel better.
“Oh man, best night of my life, I swear.” Yeah he’s said that before.
“Get their numbers?” I ask.
“Oh nah man, I was so wasted, think I still am a little.” He also never gets their numbers. I think I’ve been wrong all these years, maybe he’s not a silver tongue with the ladies. Maybe just a big bull shitter. Either way I had a great night.
There’s a knock on the glass door and I can see it’s Daniele. I wave her in.
“Sorry to bother you gentlemen but Mr Bowman is looking for you Mr Smith.” She says leaning in before slipping back out and closing the door.
“Shit shit, you got any gum?” He asks, panic in his voice.
I check my drawer and chuck a pack that I find. “Keep it.” I tell him.
“Life saver, ok wish me luck.” He slips out of my office and is away. Just as I get rid of one headache and other appears.
My phone rings and it’s Bridget.
“Please just tell me you haven’t burnt my place down?” I ask as I answer.
“Ye of little faith.” She replies. “Your place is in tip top shape.”
“Ok good.”
“Sooooo...” she trails on.
“Sooo you called me? What do you want, I’m a busy at work.” My temper has already risen.
“Yeah I’m bored, there’s nothing on your tv, there’s no booze. When you coming back.”
“Not till later. Go out for a walk or something then if you are bored. Go get your own booze!” Even though Bridget was only a few years younger than me. She always acts like a child.
“Bleeehhh, that sounds boring too. What’s your passcode for the tv, think I’ll just sit watch some porn and masturbate on your sofa.”
“Goodbye Bridget!” I instantly hang up. I can’t help it though, the image is there of her playing with herself. Something I’m sure she would actually do.
I try to concentrate on my work and manage to focus my mind. I catch up with Kyler at lunchtime and Danielle was right, the guy is smitten. He’s already arranged to meet the girl again over the weekend. I was happy for him, his last relationship didn’t end too well so its nice to see.
Its the end of the day and end of the week, now most weeks a group of us would go for drinks. Kyler, Fletcher and I normally always amongst them but not for me today. I don’t trust Bridget being left home alone too long. Kyler is heading home too, he wants a clear head for his date. Funny having a first date after already having sex, twice apparently. I’ve not seen or heard from Fletcher again.
I let Bridget know that I’m on my way back and I head for home.
When I get back there’s no intial sight of her. I call out for her but no response. Then I hear it, water running, she’s in the shower. Really.
I go towards the main bathroom that I have but quickly realise she isn’t in there. She’s in the en suite in my room.
“Bridget!” I yell at her from outside the en suite door. The scream that she gives does make me smile briefly.
“Fucking hell Jason, you scared the shit out of me!” She replies.
“Bridget, I told you I was coming home, you’ve had all day to shower but you choose now and why the hell are you in my en suite?!”
“Firstly, hi welcome home. Secondly, your other shower is rubbish. Can barely get myself off on it.”
I don’t even reply as I just walk away and go grab a drink. I sit on the sofa in my work clothes as I await her to finish. I like to get changed into more comfortable clothes when I get home but I’m not risking her walking in on me.
About ten minutes later she steps out of my room. She has one towel around her middle that covers her breasts but not much further down than her crotch. She has an other towel wrapped up around her head like a turban.
“That shower is so much better. Some power on it.” She pretends to fan herself.
“That’s what it’s there for” I say sarcastically as I try to concentrate on the tv.
“Have you used it like that before? Sprayed it up your ass and...”
“Bridget, enough! Really?” I cut her off.
“What? I’m only asking a question. Don’t need to be so touchy all the time.” She says as she comes and sits next to me on the sofa.
“I’m not touchy, you just don’t need to be so vulgar all the time.”
“Check you out Mr Nun, sounded pretty vulgar in your room last night. I found it hard to concentrate on masturbating with all that noise.”
“Fuck sake Bridget” I curse. In all honestly she could be saying it to wind me up but there’s an equal chance she’s telling the truth.
“Whhaattt?” She feigns innocence.
“Nevermind, how long are you visiting for anyway?” I ask.
“Oh I dunno, not long, just until I find my own place or mom lets me back in.”
“Hold up!” I mute the tv and turn to face her. “Say that last part again?”
“Find my own place?”
“No no, the bit about mom!” I know I heard her right but I want it her to confirm it.
“Or until mom lets me back in.” She says in a quiet rushed voice.
“What the hell do you mean?? Did mom kick you out??”
“Well yes and no...”
“It’s simple Bridget, yes or no. I can call mom and ask?!” I threaten her.
“Finnneee, yeah she says I’m old enough to live on my own and should get my own place asap.”
“That’s not all, mom wouldn’t just say that, what did you do?” Mom was the kindest loving soul and she wouldn’t just kick either of us out without good reason.
“Welllll, you know how I’m flirty and stuff.”
“Uh huh!”
“So as you know mom has been seeing this guy Robert, for a while now.”
“Oh god” I close my eyes. Mentally preparing.
“I didn’t do anything with him but...”
“But??”
“Well I’ve obviously flirted and flaunted around too much cause mom caught him wanking over a pair of my panties.”
“Oh Bridget” I sigh.
“What I didn’t do anything?” She defends herself. She may not have directly done anything but she certainly instigated it.
“Mom was right to kick you out.” I say to her.
“I didn’t do anything wrong? It’s not fair.” She whines.
“Bridget, you are old enough to know that your actions have consequences. Mom was happy with Robert and could get on with her life. Then you had to get involved.” I say quiet sternly.
“Harsh, and mom wasn’t happy. Robert was boring and controlling. Mom used to always have a glow even after...” Bridget pauses. She’s going to mention after my dad died. Her mom isn’t my maternal mother but she was better and I’ve loved her like one. “You know.” She continues. “But yeah he had to go.”
“That wasn’t your decision to make though, it was moms. Did you apologise to her?” I ask.
“Yeah of course!”
“Bridget?” I narrow my gaze at her.
“I mean I said I was sorry” she shrugs.
“Did it sound sincere and do you make her feel like you meant it?”
“I said I was sorry” she repeats.
“Ok tomororw we are calling mom and you are going to apologise.” I tell her sternly.
“Fine whatever. So what’s for dinner?” She quickly changes the subject.
“I’ll go grab a pizza and maybe some beers” I say to her letting the other issue slide for now.
“We should go out for dinner?” She suggests excitedly.
“Not tonight” I see her frown. As much as a pain in the ass she is it would be good to go out for some food with her. “How about tomorrow night?”
“Yes let’s do it!” She jumps a little too much and her towel falls from her chest. Her tits were now exposed in their full glory. I couldn’t help myself but I glance down and take them in. I hate to admit but Bridget does have a very lovely chest. Nice round tits with a cute little pink nipple. I would have to say she was probably a 32DD. I pull my gaze away and focus back on the tv which shit I turned off instead of muting.
“Ooops” she said in an innocent voice. Nothing innocent about it. I see out of the corner of my eye she cups them with her hands and rubs them gently.
“Bridget...:” I say to her.
“What it’s not like you’ve never seen tits before?”
“That’s not the point ... you’re my sister.” I say to her.
“Yeah stepsister, through marriage not blood.” Unfortunately the one time that she has to make a point and it’s valid. Still though.
“Can you please just cover up?” I ask her.
“Nah this is more fun.” She says as she stands up and lets the towel fall to the floor.
“Fuck sake bridget” I cup my hand next to my eye so I can’t see her.
“I’m going to rub lotion on my skin, you go deal with dinner.” She says as she walks towards the spare room. Again j can’t help myself but I take a glance at her nice plump ass. It looks firm yet has jiggle at the same time. God she was hot but she knew that.
I go into my room and quickly change into some jeans and a hoodie. I don’t even want to know if Bridget will try and pull something else. As I walk passed the spare bedroom where she is she has the door wide open. Yup she’s at it.
I grab my phone, wallet and head out. There’s a great pizza place a few blocks from my apartment and a store next to it where I can grab beers.
When I get back, Bridget thankfully has clothes on and is sitting on the sofa. Well when a say has clothes on, she has a white thin strap vest on and booty shorts. So there is plenty skin on show.
“Mmmm that smells good” she says as she gets up and comes over to me. “What is it?”
I open the box.
“Chicken and olives!! My favourite!” She bounces.
“I know and it’s pretty good from this place.”
“You got this especially for me?” She asks. I nod. I know it’s her favourite and I must admit it is nice. I’m a little caught off guard as she jumps to hug me.
“Aww thanks bro” she says as she plants a kiss on my cheek. A little too close to my lips as I’d like. “Beers too!” We cheers as we grab a a slice each.
We fall back into level of comfort that we had when we teenagers as we sat on a sofa watching tv together. My dad and her mom met when we were both younger. My mom turned into a crack head after getting addicted to painkillers after she gave birth to me. Addiction is a real problem and I can’t souly blame her but she wasn’t my mother anymore, she died of an overdose. Bridget’s mom, well our mom, met my dad at a support group for single parents. They set up play dates for Bridget and I, then the rest was history. They moved in, got married and lived happily ever after until mid way through high school my dad was diagnosed with cancer and it was aggressive beyond reasoning. He didn’t last long. I feel Bridget, mom and I grew a lot closer after that. I mean we still are, well mom and I are. Bridget is going through a teenage rebellious stage in her twenties.
Maybe a level too comfortable as Bridget stretches her legs out and tries to put them across my lap.
“Bridget get off.” I try to push her legs away.
“Aww come on, I’m comfy!” She whines.
“Fine” I concede not in the mood to agrue or fight. In the end it doesn’t actually bother me. I mean she does have slender soft looking legs.
It doesn’t take her long for her too try something though. She slightly shifts her body so her feet are now closer to my crotch. She then starts to try and rub my cock with her feet.
