Slow Burn Sister & Brother Pt. 02

*All characters in this story are over the age of 18*

(PART 2)

The message that I added into the chat on the account was an impulsive decision. I told a chat room full of horny men to make requests of what they wanted to see with big bids, indicating that Brian, the "camera man"... AKA my brother, would be the one selecting them. I started to realize more and more how wrong it was, this thing we were doing. And instead of turning the light red, or even yellow, I turned it green and now would have to see how it played out.

Now in my closet with the door shut, Brian was sitting right outside in that chair, most certainly reading through all of the depraved requests and comments piling on to that chat. I couldn't help but wonder what he was thinking, and if he was sharing the same strange thoughts as me. I knew I needed to just hurry up, change, and get back to him.

I stripped out of the black bra and thong I was wearing, swiftly folding them up and placing them on the dresser. I reached into one of my drawers -- my lingerie drawer. I had the perfect set in mind as I pulled them out. It was a pink, high-wasted thong and matching bra. Pretty, elegant lace, complete with a garter belt and pink leather straps that went around my thighs. I pulled up the pink thong, resting the straps high on my hips. The fabric in the front was nearly as thin as the fabric in the back, barely able to contain my soft lips from peaking out of the sides. I then pulled over the pink bra, clasping it on behind me. Next, I attached the garter belt that rested slightly over the thong. The leather straps wrapped around my thighs and attached to the garter belt. I walked over to the mirror, taking out the pig tails as I made my way to it. Standing in front of it, I smiled and admired the set, doing a spin in the mirror. In the front, the fabric was stretched up and thin, only covering the most sensitive areas and exposing skin that is ordinarily hidden, especially to him. In the back, the fabric hides itself between my cheeks and draws attention to the bubbly shape. This was it. The last outfit, then we could be done. I wasn't going to let it go any further than a few photos. Maybe a video. But that's it. It needed to stop.

As I walked out, I saw Brian's expression change again as he scanned over my body. My blonde, wavy hair was draped down my back and over my shoulders. The garments fit tight against my tone, sun-kissed figure, allowing an especially intimate view of me. I smiled and asked, "Well? What do you think?"

He chuckled and cleared his throat before saying, "That looks... like they are going to love it. But uhm... the requests."

I raised an eye brow as I stepped towards him, asking, "Are the comments pretty bad?"

He chuckled again and said, "They definitely aren't getting any better. I don't know if you would be comfortable with these..."

I smiled confidently back at him and responded, "I don't know... try me."

I could tell he was surprised by my confidence. Brian said, "Look, you're my sister, Katie. I don't want you to get the wrong idea. I would never want to cross any lines with you. I'm happy to help, but I'm just trying to do you a favor, right? None of this is because it's anything I want. Do you get that?"

I smiled and nodded my head, saying, "Of course not... so what do you think we should do...?"

Brian thought for a moment and asked, "Do you want my brotherly suggestion, or what your subscribers would want?"

I giggled and said, "Subscribers, since that's my audience."

He shrugged his shoulders and pointed to the bed and said, "Go ahead and get up there then."

I smiled and walked over to the side of the bed, crawling up and having a seat on the soft comforter, my back resting against the pillows.

He walked over and said, "No, no. I think you should come more towards the center of the bed."

I smiled and scooted myself forward until I sat dead center.

He then instructed, "Okay, now lay down flat on your back, with your feet resting flat on the bed, but move them up just under your butt."

I looked at him as I followed along with his instructions, checking back in to see if the position was right.

He smirked a little and said, "Good. Now, keeping your shoulders and butt resting on the bed, arch your back as much as you can. Really show off that arch between your shoulders and your butt."

I smiled and did as he instructed, pushing my flat stomach up in the air and thrusting my hips, giggling a little from the strenuous pose. My chest pointed upward more and more. For effect, I reached down and pulled up on the pink fabric of the thong resting on my waist, raising it a little higher and snapping it against my hips. I saw him smile as he started taking the photos from the side. Then some from above. I watched fairly intently as he scanned over my smooth complexion from my face, slowly down to my chest and stomach, all the way passed my more sensitive areas, then down to my long legs.

Finally, he said, "Okay, great. Now show off the other side?"

Without a word, I flipped over onto my stomach. I laid there flat for just a second, seeing Brian looking at me in my peripheral vision.

He added, "They're giving you $200 for just photos in the lingerie... but they said an extra $100 to see your ass in the air in this set. What do you think?"

Smiling confidently, I pushed myself up, rising up on my knees, then resting my palms down against the bed to support myself. Still on all fours for a moment, I started to lower my chest a little, arching my back and rounding my spine downward causing my butt to rise in the air. Once in position, I looked to my left where he was standing with the camera. I could feel the fabric straining against me in a way that I was certain would win over my viewers.

With an innocent smile, I asked, "How's this?"

He just smiled back at me as he walked out of sight to the end of the bed, facing the view from behind head on. I heard the shutter sounds as he said, "Katie... my God."

I giggled gently as I began to sway back and forth in an almost taunting motion.

As he continued taking pictures, with a steady voice I heard him say, "You know... they keep calling you a slut."

I giggled and continued swaying as I responded, "Yeahhh, that's all right. If they're sending me their money, I don't care what they call me."

I saw him move to the other side of the bed, still taking photos. He again asked, "You don't think they're right about that, at all?"

He had a playful smile on his face that immediately made me mirror the expression. "Wowww... now you're calling me a slut? That's interesting."

He chuckled again and playfully responded, "No, that's not what I'm doing. I'm just saying... look at the situation. The teasing, the outfit, the poses. I'd say you might be a little bit of one." Again, he had this strange teasing smile on his face; as if the word 'slut' had never been meant as an insult before.

I smiled back and said, "Maybe I like being one just a teensy bit."

Brian took a few more pictures, but had a slightly more excited smile on his face. He said, "I bet if you said that into the camera in a video, they would go insane for it..."

I giggled and said, "Oh yeah? You dare me?"

Without speaking, I watched as Brian moved again to the end of the bed to get a full view of my barely covered ass swaying back and forth. I then heard the sound of the 'Record' button and looked back at him while swaying, letting out a soft and seductive, "I love being a little slut..."

His eyes looked like they were about to pop out of his head as he stopped the recording and started tapping away at the screen, likely posting the photos and the little video. I probably didn't need to say that. No. I definitely didn't need to say that. That was too far.

I pushed myself back up and rolled over to the side of the bed, adjusting the pink set as I stood up. "I guess we could probably leave them with that, huh?" I stretched a little in the set as Brian's eyes stayed glued to the screen. "Hello?" I asked.

He then shook his head and showed me the phone. Messages, gifts, and requests were populating by the half-second. So many different requests with varying degrees of dirtiness.

"Lose that bra baby, come on ($200)"

"Let's see a camera man POV lap dance (pants down, enjoy yourself ;)) ($300)"

"She needs a good spanking... over the knee ($300)"

I just looked back at Brian, not really sure what to do. That major line we've been treading... this is it. Any one of these would completely cross it.

I read the requests and said. "Oh wow... those are pretty...interesting. Now they want you involved!"

Brian looked a little troubled. I could tell by his face that he was conflicted by all of it; the idea of seeing me topless, the notion of giving him a lap dance, and the thought of him spanking me. It was all completely outrageous. He then looked at me and said, "We can't go through with these Katie. It's too crazy."

Half kidding and playing aloof, I looked back at the messages and then back to him asking, "Crazy? How do you mean?"

He responded, "Come on. You would never take your top off in front of me. We won't even get passed the first one of these requests. We should just call it."

I laughed at his remark and replied, "Seriously? It's not like you haven't seen me topless before!" I paused for a moment and added, "Was it that 'pants down' comment?" I smiled teasingly and tried not to allow my eyes to glance down his frame.

He nervously responded, "No, no. It isn't that. I just don't want you to..."

I cut him off and added, "...see how excited you've been getting...?"

He looked stunned for a moment, and then tried to play it off by responding, "Come on. That's crazy, Katie. You're my sister. You think I've been sitting here getting hard looking at you all day like some perv?!"

I giggled and said, "You haven't? Prove it then."

He laughed and said, "This is ridiculous. I just wanted to help you out. That was the whole reason for any of this. I didn't sign a waiver to be featured. And I get nothing out of proving myself to you."

I smiled mischievously and said, "Fine, fine. I was just messing with you."

He then looked at me like he had some sort of epiphany. "How about this: you take your bra off and I'll snap the photos. When I prove nothing 'happened' from seeing you, I get to keep the money from that request." He looked at me as I thought about the idea. He then added, "Come on! How confident are you?"

I scoffed at him with a smirk and asked, "Okay, and what about if something does 'happen'?"

Brian folded his arms across his chest and responded, "You hang on to the money, and I'll help you with the next request."

I looked at him skeptically. Such a bizarre arrangement when broken down; If my brother is not turned on by the sight of me half-naked, he gets $200. If he is, I give him a lap dance that he records. It felt so completely unreal. I had difficulty tracing the path from the first photos he took of me today to this moment now. How did we even get here. Maybe I had been mistaken in what I thought I saw earlier. Maybe my eyes deceived me before and I saw something else in his pants, and he truly has been seeing this as just assisting me with a task. But then again, I remembered the way he looked at me before. The way his eyes were glued to my body, exploring areas with his eyes that he had never examined before. And with my power and ability to put an end to all of it, I refused to do it.

I looked at him confidently and said, "Okay, deal." I stuck out my hand and shook his. Even as he shook my hand, his eyes couldn't help but travel below my neck. I had a strong intuition telling me how this was likely going to play out.

Brian walked over to the chair near my desk, spun it around and took a seat. Holding my phone up in the air and looking at me, he challenged me with the words, "Your move."

A seductive smile took over my face as I walked closer to him, standing nearly five feet out from where he sat. I turned around to face away from him, the pink fabric pressed tightly against my hips, ass, and back. The pink leather straps were tight around my thighs as I adjusted the garments around my lower half. I then began to raise my hands up behind my back, pinching my index finger and thumb on my right hand over the little pink clasp holding the bra together. Suddenly, it popped, the straps falling down my lower back. My left hand held the bra pressed against my chest as I turned back around to face him. The straps draped down my sides.

The only thing keeping Brian's eyes from the delicate sight underneath was my left hand holding the bra in place. He took photos as I started to lower my left hand, slowly but surely lowering the pink garment down revealing more and more skin until a trace of my little pink nipples came into view. He seemingly unintentionally let out a soft gasp as they came into view. Seconds pass and the bra was lowered over my stomach, my breasts on complete display to Brian for him to snap the photos. I dropped the bra to the floor and then looked back up at the camera, standing with my arms down by my sides and with my shoulders back. His expression behind the camera was that of a man in awe by the sight before him. I bit my bottom lip gently as I raised my hands up to my breasts, pinching my nipples softly as I posed for the final photos in the series.

I placed my hands on my hips, my upper half now unhindered by the strain of any garment. "Well?" I was curiously peering over into his lap, wondering if any noticeable physical reaction could be seen.

I watched as he tapped away at my phone, likely reviewing and posting the photos he had taken on my account. He raised his hand and waved me to come closer, his eyes staying locked on the phone. I slowly took a few steps forward until I was nearly knee to knee with him.

Brian raised an eyebrow and with a smirk responded, "You owe me $200."

I laughed and in disbelief argued, "Shut up... no way!"

I watched as he reached for the button of his pants, stood up for a moment, undid his zipper, and then pulled them down to the floor. I was surprised to see the normal sight of the gray boxers with no signs of any significant reaction. I couldn't believe it. I must have been imagining all of it.

Looking somewhat embarrassed, I looked at him and said, "Okay, I guess you were right then..."

He smiled up at me and said, "I was. But tell you what, I'll give you another chance. Do your little lap dance. I'll at least let you make up for what you lost."

Although Brian was not physically showing any signs of excitement, the fact that he suggested we complete the next request spoke volumes. Why would he suggest it if he didn't want it? If nothing else, this was my chance to find out once and for all if I was correct. We would just do this last one. If nothing happens, we can both go our separate ways and never talk about this again, returning to our normal brother/sister relationship. If something does 'comes up,' who knows what will stop us.

Brian held up the phone again and aimed it at me. Without warning, I heard the sounds of the record button. Standing only inches away from Brian and facing him, I put my hands up and over my head for a moment, bending my body, showing off my delicate curves and swaying from side to side. I lowered my hands to cover my breasts, massaging them gently for a moment and then pinching my nipples while biting my lip. Brian's face behind the camera intensified at the sight of me. I took another step closer to him, causing him to lean all the way back in the chair in order to keep me in frame in the video. Smiling down at him seductively, I began to turn around slowly. My knees were lined up with his as I started to bend forward at the hips. My phone in his hands was only a foot or so from the view of the tight, heart shape being flaunted in his face with the pink patch of fabric straining against my plush mound.

I heard him mutter, "Jesus..." under his breath, causing me to giggle as I began wiggling back and forth.

"Is everything okay?" I asked tauntingly as I looked back at him, continuing to shake my cheeks in his face. "No touching..." I whispered, as if we were in a strip club and he was receiving a personal and private dance.

He smiled back at me and answered, "God... you really are a little slut, aren't you?"

I smiled back at him as I stopped swaying and lowered myself down. Inch by inch I lowered until my ass made contact with something stiff and warm.

I felt it begin to press into me as I looked at him and with a soft giggle said, "I knew it..."

His breathing deepened as he responded, "You're being very bad."

His words caused me to giggle as I fully sat down in his lap, holding on to his knees with my hands for support. I felt his stiff cock press firmly in between my cheeks. I pinned it down against his lower abdomen, feeling it against every inch of the pink material separating he and I. I then started to slowly rotate my hips on him, in a back and forth motion. I looked back at him as he angled the camera down into his lap to record the action. Every few seconds, he let a soft moan escape through his gritted teeth. All of my suspicions were confirmed. I had been right all along, and this is what he had been yearning for since I modeled my bikini for him earlier in the day. Now this; feeling his large cock pressing against me. I felt such a thrill and an intoxicating sense of control.

Nearly a minute and a half had passed by of me grinding into his lap. He seemed to grow stiffer by the moment as he held the phone up capturing the view. He sat back in the chair, feeling me pressing into him. I almost thought I felt something wet against me, quickly realizing it was likely his pre-cum... as well as my own excitement slightly soaking through our respective fabrics. I could feel his body tensing and twitching under me, as well as his breathing getting deeper, yet inconsistent. I then stopped suddenly, lifting myself back up, leaving him sitting there in a slight daze as he ended the recording. As I looked back at him, his cock was standing straight up in his boxers. He went straight to tapping away as he queued up the video to be sent.

I turned around and stood there facing him with my hands on my hips, and with a victorious smile I said, "See? I knew it."

I heard him send the video in the the chat as he looked up, pointed to the wall behind him, and instructed, "Grab that tri-pod you have there."

I smiled curiously as I retrieved it for him, returning to stand in front of him. He stood up and took it from me, quickly getting my phone in place. He set the phone on Selfie-video mode and placed it a few feet to his right. After a few adjustments to the position, he sat back down, adjusting his still stiff cock in his boxers.

He looked up at me and said, "Hit record, and then crawl over my lap with your ass facing the camera."

I looked at him and said, "What? Now you're going to spank me for being bad?"

Brian replied, "Rubbing your ass against me like that and being a slutty little tease for your fans has consequences. Now do what I said." He said this seemingly without a shred of reluctance in his mind.

Obediently, and feeling slightly nervous, I walked over, hit the record button, and then proceeded to crawl over his lap. Looking in the phone's frame, his face was hidden from view entirely. Only his body and mine could be seen. Approaching from his right side, I placed my hands down across his lap on his left thigh as I lowered myself down, nearly grazing his large manhood still sticking straight up. I then started crawling over his thighs, my hands touching the floor on his left side. Finally, I was draped over his lap, my legs dangling off his right side, my torso off his left, and my nearly naked ass directly under his face, willingly presented to him. I felt him drag the fingers of his left hand from the middle of my bare back, down to my lower back, then down over the garter belt. His right hand met his left as he undid the garter belt and detached the leather straps on my thighs, loosening them and allowing them to dangle off of me. He pulled it all off of me, leaving only my pink thong covering me. The surprise in the motion caused me to gasp for a moment. And before I could think, I felt the impact of his right hand crash against my right cheek with a firm 'SMACK.' I let out a soft whimper sound from the first smack, not expecting for it to be that hard.
