I was sitting alone in my room reading a book. It was raining pretty hard outside so my usual cycling or running was not happening that day. My sister Clara was home too, she had been listening to music but had went quiet until I heard a crash, followed by lots of cuss words then silence again. Our bedroom was adjoined by a bathroom, so I opened my door and yelled to her.
"You okay Clara?" I said.
"Yes, I'm fine," she replied but her voice sounded strained.
"Are you sure?"
"I'm fine."
I left her alone, her second 'fine' sounded very abrupt but I didn't want to annoy her. About 20 minutes later she knocked and came into my room, she was wearing a robe which I found odd since I didn't hear the shower. She was holding a very broken camera in her hands.
"Can I borrow your camera and tripod?" she said quietly.
"I don't have a tripod, what happened to yours?"
"One of the legs wasn't locked properly and it fell and knocked over my light which pretty much destroyed my whole setup. It's what I get for buying the cheaper stuff."
"You have a Nikon, do you even know how to use mine? I remember you not liking it, the basics are the same but the settings frustrated you. What do you need it for?"
"I... Do you promise not to tell anyone?"
"Who would I tell, sis?"
"I, I've been paid to do a custom shoot on my page. No face, just the lingerie he bought and sent to my post office box. I've already been paid for it and it's due on Friday. The site will ban me if I don't deliver and I already used the cash to pay off my phone bill."
"Who is he, how much are we talking about?"
"I was behind on my bill, Mom said I had to learn and pay it myself. $400."
"Wow, someone is paying that to see you in lingerie?"
"Oh fucking thanks, I'm already upset but that's kinda rude."
"Hey, I didn't mean it like that. Is it just a lot of money and to not see your face?"
Clara put the camera down and opened her robe. The lingerie was beautiful, almost see through white lace, I could clearly see her nipples and the fact that she shaved or waxed her pussy. She usually wore baggy clothes, seeing her body outside those was eye opening.
"Oh. Holy shit Clara, you really are stunning," I said, feeling my face go red.
"Well I don't like to show the world, guys in college are so crude and only want to fuck me."
"But you have your own web page?"
"Well yes, they don't see my face and they pay for the privilege. I'm just starting out but I already started picking up regular subscribers and this guy sent me a custom shoot request. I get to keep the lingerie too but he said I can't use it on my regular page since he's paying so much."
"Well I don't have a tripod, I can set up the timer or something. Did the light break too?"
"Yes but I have a spare one of those that might work. Maybe, um, maybe you could take them for me? If it was just my regular site pictures I'd be okay, I have 3 weeks of posts queued but since this is a custom."
"Wouldn't that be a little awkward? Taking sexy pictures of my younger sister?"
"It's not full nude, I'm 18, I'll pay you once I get caught up."
"Against my better judgement, I'll do it but I'm not taking your money."
"Thank you," she replied with a grin.
Seeing Clara's face light up as she bounced back into her room was worth it to me. She was only a year younger but I liked seeing her happy. We got on pretty well, she was quiet and didn't have too many friends but did her best not to annoy people or do anything to be noticed. Learning she had an adult site really blew me away.
I gathered up my camera gear and walked into her room. It was set up almost like a mini studio, I was impressed. I grabbed one of her little mirrors and used it to reflect some light onto what was left of her diffuser and combined with her backup light, had a pretty decent set. I checked the settings on my camera, put in a blank memory card and waited for her to pose. By the time we were done I had taken about 70 pictures, they started out tame enough but progressed to her in very provocative poses and a few of them were to be topless. I'd always get in a zone when taking nudes. I'd taken them for exes in the past, I'd focus on getting the best shot, the best focus of the beautiful woman in front of me. I tried to put it out of my mind that my current subject was my sister.
When we were done I handed her the camera to let her look through and hoped she didn't notice my erection.
"Oh wow, these are amazing, thank you!" she said, clicking through them on the camera.
She was still topless and despite taking the pictures I couldn't look directly at her, she noticed of course.
"You're so funny, you've just taken pictures of me in sheer panties with my legs open but you can't look at me with my breasts out?" she said, giggling.
"I uh, I get into the zone with the pictures, it's different because of who you are," I mostly stammered.
"Is that why you have a boner?"
"Well, you're pretty sexy when you're not in your usual baggy clothes sis."
She put on a robe then stood up and kissed me softly on the lips.
"Thank you, I really appreciate you doing this. Can I help you edit?" she said softly.
"Uh, sure."
I had hoped for some alone time to jerk off, get it out of my system but she followed me to my computer where I plugged in the camera and started the upload. Once in editing I applied my usual tweaks to them all then had her look to see which ones needed more. We only found a few where I had to blur out her face but looking at her body while she sat right next to me was torture and I could feel my cock throbbing. When we were finally done editing I set them to process which always took a few minutes.
"I uh, I'd like to give you a reward, these are way better than I could have taken alone," she said quietly.
"What do you mean, what reward?" I replied.
"I want you to accept this, no argument, no hang ups, just close your eyes and enjoy."
I tried to say something, to ask more but she put a finger over my lips and stroked my cock through my shorts with her other hand. I tell myself I should have stopped her but I was in a trance. She had me help her pull my shorts off then immediately took my cock in her hand, saying 'oh' quietly before stroking me. She leaned forward then slowly began to lick and suck me. I closed my eyes in ecstasy, she was very talented with her mouth and tongue and was pretty turned on already. I didn't last too long, I warned her I was going to cum but she sucked me harder and I groaned as my cock exploded, spraying my seed down her throat as she looked up at me. She swallowed every drop then quietly helped me pull my shorts up.
"Th... that was amazing, thank you," I said to her as she sat in the chair again.
"You are very welcome, I didn't know you were packing one so big," she replied with a smile.
"I'm not that big, 8 inches isn't huge."
"Well it's bigger than I've had before so there."
"How many have you had?"
"Not telling. Are they done?"
"Yes, I'll put on a thumb drive for you."
