To cut the introduction short: I (Pascal M 28) got into photography a few years back, got on quiet a professional level, built up a small portfolio and offer professional shootings now and then.
It's not like I have a big business going with day-to-day shootings, but all my friends recommend me to other people so I get asked to shoot for them.
The most recent request came from my sister Cathy's (26) best friend Ronda (27).
My little sister told her that she wanted to take some new passport photos, so Ronda asked if she could join in and get some of herself as well for new job applications.
We agreed to meet up on Saturday as I had nothing else planned for the day.
I have been single for 1 and a half years now and actually enjoyed it.
I never actually did this when I was younger. Most of the time I've been an introverted guy, too shy to speak to girls.
Although I managed to get some girlfriends, I was not the type for one-night-stands or flings.
But as my last relationship ended after I caught my ex cheating when trying to surprise her by coming home early, I decided to change this behavior and go all out and enjoy a new boundary free sex life.
I would not consider me as an attractive guy, but I got rated as slightly above average from some women which in combination with my character is apparently enough for some to bring me to bed.
To embrace my photography hobby, I built a small room in my backyard with a photo studio inside so I would not have to move my equipment after I am done.
Inside is a changeable background, some lights, flashes, a changing corner and a red chaise lounge which I occasionally use for shootings but would most of the time stand aside and get used by clients to wait or look at the finished pictures.
I recently also added a small bar with different liquors as a small shot helped some customers to loosen up and get comfortable around a camera.

Time went by and Saturday morning came.
I woke up at 9am, ate some breakfast while watching YouTube videos.
To stay professional at my shootings and not get any dirty thoughts with customers, even at normal shootings (you can never be too safe), I always masturbate before setting everything up.
I got into the shower, took some extra soap and started going at it.
Usually, I think of the last girl I was in bed with, but today was different.
There was something else I could not get out of my head, a dream I head the night before.
I dreamt of getting wild in the parking lot with a girl I met partying, but I knew this girl, she seemed very similar.
I was fucking her from behind on the hood of my car and as she turned her head around to moan at me, I finally knew who she was.
It was Cathy.
I dreamt about fucking my own sister.
I was pretty weirded out, but at the same time it was an arousing thought.
I have never seen her like that, but I have to admit she grew into a beautiful woman, blonde hair, slim figure, long legs and a face that could melt your heart.
I remembered once rescuing data from her dead laptop hard drive and accidentally stumbling over some nudes from her she took in my room while I was away studying.
I still have them stored away on an encrypted drive. It felt weird at the time and I wondered why she was in my room.
But curiosity got the better of me and I researched them before getting into the shower, and thank God, I did not delete them, they did their justice to let my dick rise up.
So right here in the shower, with my member in my hands and the visual of her bent over in front of me this was enough to get me over the edge faster than usual.
I came at the thought of my sister, this was a first, but even with post-nut clarity I was sure that this would not be the last time.
I got dressed at went over to the studio, preparing a chair and a grey background before making some test shots of myself.
Everything was ready, I just had to wait for the girls to show up.
___________________________
Shortly after 11am they knocked on the door and I let them in.
"Heeeyy Bro!" my sister greeted me with a hug.
"Long time no see Pas!" Ronda followed while also hugging me.
She was right, last time I've met Ronda was shortly after I turned 18 and drove my sister and her to pick up some food.
And oh boy did she grow up since then.
She's always been very sporty and had a fit figure she maintained.
The most obvious change were here breasts pressing against my chest, they were some D-size and proudly brought to display in a silky blue blouse.
The dark blonde hair was tied up into a bun with some strands hanging from the side.
Her firm ass fit perfectly into the tight white, to a small degree even see-through, white pants.
Damn even though I masturbated before, I was sure that this job was going to get tough.
My sister laid down her purse in front of the couch and went onto the chair in front of the camera.
She wore one of her favorite summer dresses, a green one with flowers on it.
Although it did not show as much cleavage as Ronda's blouse, it definitely complimented her body and did not leave much to imagination.
Her blonde fine hair with silver strains was around shoulder length and the style is apparently called 'tousled lob' with some silver strands.
I really liked her new retro-styled glasses which she asked me to help decide.
I caught myself checking out my sister while Ronda let go of me and went to sit on the couch.
Cathy sat slightly angled to the camera and adjusted her posture to straighten her back which caused her chest to stick out and define the curves of her boobs some more.
I took a look through the viewfinder and started taking her photos.
It didn't take long until we had some brilliant portraits of her, no wonder with such a natural beauty.
She soon was happy with the result and let Ronda have her turn.
She sat down, picked on her Blouse to straighten it followed by grabbing her bust to align her bra. I watched all this through the camera, glad that it hid my face so nobody saw my jaw dropping.
"Looking good?" Ronda asked Cathy.
"You look like you'll get any job you want!" Cat answered with a wink.
I took her photos in several poses and showed the results.
"Wow you sure deliver as good as everyone told me." Ronda complimented me.
"Thanks, glad I can help out with my hobby." I answered.
"So, Cat, should I tell him or would you like to?" Ronda added.
I was a bit confused as I thought we were finished.
"No, it's fine, tell him." Cathy told her.
"Well, we had our weekly Ladies night yesterday," Ronda started.
Oh, I remember these nights back when our family lived together, lots of laughing and fun for them, less sleep and more gaming time for me.
"and we wanted to ask if you could take some more pictures of us?" she said with a shy undertone while biting her lip.
"Sure, why not, I have nothing else to do today. What kind of pictures?" I asked them.
"Some more explicit ones!" my sister hopped in.
I looked over to her sitting on the couch and smiling at me. I must have looked a bit overwhelmed by this question.
Not because Ronda wanted me to take erotic pictures of her, I had several shootings like these, but because my sister also wanted some taken of her.
Looking back, it should not be too surprising, she was always pretty open with her sexuality.
Walking around in just a towel or her underwear, moaning pretty loud when having sex or masturbating in her room and also, she must have had in mind that I could find her nudes on that hard drive.
She caught me masturbating a few times as a teen and was not scared but instead walked away while smiling at me.
For some this sounds like a porn plot. But to past me it was frightening and a bit awkward afterwards.
"Okay, so what do you have in mind?" I said after clearing my throat.
"We each picked a pair of our favorite sexy underwear yesterday and already wear it." Ronda proudly told me.
I got equally excited and nervous after hearing this.
So, to get us all comfortable I went to the bar and offered them a shot. I poured my sister and Ronda some sour apple liquor as I knew it was their favorite and myself a shot of whisky.
Ronda asked where she could change so I showed her the corner where she could close a curtain.
When I turned around, I noticed Cathy stepping out of her dress and getting a pair of dark green high heels out of her purse.
Apparently, her favorite sexy underwear was a dark green lacy mesh string and a matching push-up bra.
This in fact made her look sexy, the bra made her B-cups look like C-cups and the string rested perfectly on her waist.
As she stood up to put on her heels she turned around, stepped on a small stool and bent over I was able to check out that perfect firm ass of her.
Suddenly my mind flashed back to the scene from my dream and the view looked pretty familiar, even her body proportions matched.
"What poses would you recommend?" Cat soon asked.
She caught me off guard. Quickly snapping out of my thoughts I led her over to the camera and suggested that we would start with a few standing poses.
"Alright. We looked at a few poses we liked yesterday, I'll try them." she added.
And they worked.
I decided to squat while taking pictures, I told her so I can get better angles, but that was a lie, I felt my dick twitching and growing so it was an attempt to hide my inevitable boner.
A fight began.
A silent fight between me and my penis. I tried to resist, get other thoughts. Trying to stay professional, a photographer and not some pervy brother staring at his sister's body.
"You guys are already warming up huh?" Ronda joked while she peeked out from behind the curtain which she held covering her body.
"Are you alright Ron?" Cathy noticed that Ronda seemed to be hesitant with stepping out of the changing corner.
"Yeah, it's just," Ronda nervously said, "maybe it's a bit too revealing."
"What? But you have nothing to be ashamed off, right?" Cathy looked at me waiting for confirmation.
I nodded.
"And no one, besides us two will see you, there's a huge hedge surrounding the backyard, also the windows are mirrored from outside." I added.
"Sure, it's just," Ronda looked up and down on me.
"Oh," I realized, "Ooooh I get it. It's me."
