**This is the fourth part in a series. The first part is A New Job: Casting a Classmate**

I was in shock from what I had just learned. I couldn't believe who was staring down at me. My body was frozen, and my mind spun in frantic circles. There was no way I could process what had just been revealed to me.

I was laying naked on a small stage in the middle of a party for the porn company I had started working with. The party had started off wonderfully. I was working as a free use waiter, along with three incredibly sexy girls. One of the girls was Paige, my high school crush who had filmed a sex scene with me a few days before. The other two were Rosie and Emma, good friends of Paige. There was hardly a shred of clothing between all four of us, and not a single piece did anything but highlight our bodies.

We all had been relentlessly teased and used by the other guests, who had also enjoyed the party by participating in some extremely lewd games. It had all led up to me fucking both Rosie and Emma on the stage. I had just filled Emma's pussy with my cum, and was recovering my strength as I lay on the stage.

That's when the unthinkable happened. A woman had approached me. This woman had watched my performance with Emma and Rosie from afar. Her face was covered in a mask, but there had been something about her that had made me think she looked familiar. That sense had been proven correct when she walked up and spoke to me. Much to my horror the voice belonged to my step-sister Helen.

Helen wasn't even supposed to know that her friend ran a porn company from the home we three lived in together. She definitely wasn't supposed to know that I had started to work for Sofi, starring in her films as her first male talent. But here she was at the party, acting extremely casual about seeing her step-brother fresh from just fucking two young girls in front of both dozens of other people and a multitude of cameras.

I was too shocked to speak, so I just stared up at Helen. My step-sister laughed lightly at my stunned reaction, giving me a playful smirk. She sat down on the edge of the platform, right next to me. Reaching out she brushed a hand over my chest.

Her touch felt far too good, and my dick stirred slightly despite how recently it had been drained. As I looked up at Helen I couldn't help but focus on how tightly the dress hugged her curvy body. My eyes were drawn to the cutouts in the dress, revealing a good amount of her gorgeous body underneath the dress. The most alluring spot was the window that provided me an excellent view of a generous amount of her cleavage.

It was only recently that I recognized just how incredibly hot my step-sister was. During the filming of one of the porn videos Sofi had teased me with salacious hints and details about Helen. Ever since then I couldn't help but feel my heart beat faster when thinking about her, and my mind turned to lustful desires as Helen trailed her fingers up and down over my chest, lowering them towards my waist.

"You did a really good job up here. You fucked those girls like a real pro, Sofi must have been teaching you a lot about how make a woman go wild." Helen told me.

It was so incredibly strange to hear her speak so casually about my sexual prowess. We had never discussed such things before, and I was still struggling with the issue that she was present at this event at all. She was supposed to be out of town with a friend, so I had no idea how she had figured out what was happening and snuck in.

"How... Why... What the fuck are you doing here?" I whispered out.

I tried to keep my voice low, though my frustration and confusion made my voice hard and harsh. I desperately didn't want anyone else to figure out that it was my sister behind her mask, so I was trying to keep any attention from being drawn our way. I also didn't want anyone to overhear me talking with Helen, though she spoke at a normal level.

"What? Can't a sister come and support her little bro? This is a big day for you and all, so I wanted to come and see how you're doing at your new job. And I have to say I enjoyed seeing you perform for us all." She teased me.

Her words both excited me and sent dread into my heart. I wondered with horror just how much Helen knew about my activities with Sofi and her business. But I also was thrilled to think that she enjoyed seeing me fuck Rosie and Emma. My cock stirred a little more at this thought, and it started to grow. Helen's eyes flicked down towards my dick, and a devious smile spread over her lips.

"How did you know about this? Sofi said you didn't know a thing about..." I began to say, but Helen cut me off with a roll of her eyes and an exasperated sigh.

"Sofi doesn't know that I know, but I've known for a very long time what she does." Helen started to explain, looking me in the eyes.

"When she started off this porn thing she recruited her friends to help out. And since her friends are also my friends, of course I eventually heard what was going on." As Helen continued to explain her hand idly drifted back and forth along my waist. "I never let her know that I figured it out, and eventually it became too awkward to tell her that I've known almost the whole time. I let her keep her secret, and I made sure to let her know that I wasn't going to ask questions about what she did."

I let out a low sigh of relief. At least Sofi hadn't been lying to me about not telling my sister what was going on. And I was also relieved that this wasn't all just a prank by Sofi. It would be just like her to tease me even more by bringing my step-sister to watch me have sex after infuriating me with scandalous details about her.

But I still didn't know why Helen was here. And it was an even greater mystery why she had stuck around and watched me when she saw me fucking Rosie and Emma. She had said she enjoyed the show, which confused me greatly. Her hand was also getting dangerously close to my cock, which was steadily but slowly getting harder from her teasingly light touch. I tried not to even think about how much of my growing arousal was because of how good Helen looked in her skimpy dress.

"So um... You came here to see some of your friends?" I asked, hopefully trying to move the conversation along and distract myself from how longingly Helen was staring down at my cock once more.

Helen smirked and giggled playfully, shaking her head. "No, not quite. I wouldn't risk Sofi figuring out that I knew about her business just for a meet and greet." She said, dispelling my hopes that her finding me here was just a casual coincidence.

"When some of my friends heard that you were Sofi's new playtoy, and that there were rumors flying around that you had a delightfully wonderful cock, I just had to come to see if the stories were true. And from how you made those girls scream in ecstasy as you pounded their tight little cunts, I think the stories were underselling your talent."

Helen spoke in a softer and more sultry tone. She also moved her eyes from my cock back up to my eyes. Her expression was hidden partially by the mask, but her gaze was full of desire and lust. Her hand reached further down, and her fingers wrapped around my cock. It quickly swelled in her hand, growing half hard in her warm grip.

This was too much for me. I had just laid still the whole time as I talked with Helen, mostly out of fear that doing much else would draw far too much attention to me from other guests of the party. But having my step-sister grab my dick was enough to push me into action. I sat up and reached down to push her hand away, staring hard at her. I might have had my own desires and fantasizes about her, but the thought of doing anything with her was still too crazy for me.

Helen acted offended as I removed her hand from my dick, and her mischievous smile turned into a pout. Crossing her arms in front of her I could tell that behind her mask she wore the expression of a spoiled child who had just had a new toy taken away. But she didn't move away, and actually scooted a little closer to me as I sat up and covered my cock with my hands.

"Now that's not very nice at all." Helen whined, her voice full of faux distress.

"I thought Sofi had said all you helpers were completely free use. Will I need to call her over so we can figure out why you suddenly want to ruin her perfect little party?" Helen asked.

I saw a devious look in her eyes as Helen looked at me. She had put me in a very difficult spot very easily. I knew that if she brought Sofi over then Sofi would quickly realize that it was Helen behind her mask. I wasn't quite sure what would happen after that, but from the way Sofi loved the taboo she was almost certain to help my sister tease me even more. And if Sofi was involved that would bring even more attention to whatever lewd things I was doing with my step-sister. As it was right now, no one else knew that I was sitting naked next to my sister. I desperately wanted to keep it that way.

That meant not making a scene. I briefly considered just getting up and leaving, but Helen could use that to draw just as much attention to us as me simply denying her would. As much as I didn't understand why Helen wanted to touch my cock, I came to the conclusion that it was the best idea just to let her.

Letting out a soft defeated sigh I moved my hands away from my crotch, leaving it open to Helen. My sister grinned wickedly and quickly moved her hand back to my dick. She stroked it gently, and it quickly grew even harder. Despite how much I was resisting doing anything sexual with my step-sister I couldn't deny my desire for her. My mind might rail against it, but my body longed for her.

Helen was quickly pleased by how my cock reacted to her touch. Her strokes got faster as it grew in her grip, and she swirled her thumb over the head of my dick. I let out a low moan, trying not to let her know how good she was making me feel. I also tried not to leer too much at her, but that was difficult. The way she was leaning forward made it look like her tits were about ready to spill out of her dress. I pulled my eyes up from her breasts to her face, and below her mask I found Helen smiling with satisfaction at me.

"Do you like what you see? I think you must. You cummed so much only a little bit ago and you're already getting so hard again. You must be enjoying something." She said, grinning at me.

"I uh, it's not... I'm not trying to..." I fumbled out. I was trying to put together a reason for why I had been staring at her tits, but I couldn't find the right words.

Helen giggled at my mumbling explanation, and I saw a mischievous spark in her eyes as an idea popped into her mind. Keeping one hand on my cock she moved the other to start untying the strings that held her dress together. Seeing that a surge of excitement coursed through my body, and my cock throbbed in anticipation. Feeling my reaction Helen giggled again and worked even faster to undress.

"Perhaps you are staring at me because I'm the one of the few people still fully dressed around here. Makes me stand out. Maybe you'd feel more comfortable if I got rid of this dress." Helen said teasingly as she loosened the dress.

I thought about trying to stop her, but I didn't know how to do that without making a big scene that would draw more attention to us. Any more attention and I was sure that people would soon know that I was being jerked off by my step-sister. For the sake of trying to keep Helen's presence at the party a secret I just let Helen undress. Once she had untied enough strings the dress nearly fell off her, and with a few quick movements Helen pulled it fully off.

With the dress off I couldn't help but stare lustfully at her gorgeous body. After taking off her clothes Helen stretched out her legs and sat beside me. Much like the other guests she hadn't been wearing anything under her dress and was now completely nude.

Helen was seductively curvy, with an hourglass figure and proportions that seemed to defy the limits of the human form. Her breasts were perfectly round, and hung high even without a bra to support them. She leaned back and turned her torso to me, letting me see just how lovely her tits were. I gazed longingly at her tits, but my eyes were also drawn down her body. Her soft thighs were thick, and I just knew that her ass would be ridiculously plump. Watching me stare at her Helen spread her legs open a little, showing off the glint of wetness coming from her pussy.

"Is that brotherly love in your eyes, little bro? Or do I see some depraved lust in the way you're looking at my pussy?" Helen asked.

Teasing me even more as continued to stroke my cock as she reached down and brushed the fingertips of her other hand over her pussy. She spread her outer lips for a moment, giving me a view of just how wet her pink pussy was. The more I stared the more Helen smiled, finding satisfaction in how captivated I was by her sexual beauty.

What I still didn't understand was why Helen was doing this. She had never even remotely given hints that she wanted this from me before. Her clothing was normally fairly conservative, and ever since she had gotten to know me she had acted like a normal step-sister. But I was beginning to not care too much about her motivations. It felt good to have her soft hand stroke my dick, and it was amazing to see her present her gorgeous body to me.

"You just going to keep teasing and tempting me, big sis? I can only take so much, you know." I sighed out.

I hadn't planned to say those words, but they were the truth. The combination of her touch and the sight of her body had gotten my cock fully hard, and it was aching for more than just her hand. I couldn't help but think back to what Sofi had said about my sister and her sexual exploits, and I wondered just how far she was willing to go. I still wasn't comfortable enough to directly suggest that she do something more with me, but I looked at her with heavy anticipation in my eyes.

Seeing my gaze Helen grinned in triumph. It appeared like she had been wanting this from me. Both my words and my more eager gaze pleased her, and she inched a little closer to me. I looked down at her breasts as they swayed from the movement, hypnotized by their motion. I wanted to reach out and grab them, but I wasn't quite bold enough for that yet.

"I can do a lot more than this, big guy." Helen promised me, licking her lips. "But first you need to lay back down."

Taking in a breath I gathered my resolve. I still had my reservations, but they were growing easier to overcome. My desire and lust were burning hotter and more urgent inside my chest. I was even starting to doubt why I was even resisting at all. Helen might be legally my step-sister, but it wasn't like we had grown up together. Our parents had only gotten together relatively recently, so it wasn't so strange for me just to treat Helen like the incredibly sexy woman she was. With my mind more at ease I laid down on my back, waiting for what my sister had in mind for me.

I wasn't too surprised by what she did next, but I found myself happier than I had anticipated. Helen got up onto her knees and then moved herself over my head. Her soft thighs were lightly pressed on either side of me. She had let go of my dick, and was resting her hands on my chest as she hovered with her pussy just above my mouth.

"I've heard Sofi has trained your tongue pretty well. Care to give your big sis a sample of what you can do?" Helen asked.

As she lowered her hips down I raised my hands, letting myself be more bold and enjoy the situation I found myself in. At the same time as I flicked out my tongue to greet her pussy I ran my hands over her waist, moving up her sides. Helen moaned gently as my tongue ran over her, and she sighed out in pleasure when my hands moved to her breasts. If I was going to do this, then that meant I was at least going to get to feel my sister's amazing tits.

Helen raised her hands to cover mine, holding them to her breasts. I squeezed her huge tits as my tongue swirled in changing shapes over her pussy. She pressed herself down a little more against my tongue and lips. Her cries of delight got louder, indicating how good she thought I was. I felt a spark of joy hearing her moans, and it motivated me to try and give her all the pleasure I could.

"God yes, oh use that sweet tongue of yours. Make me moan and squirm so pretty for the cameras." Helen moaned out above me.

A sudden jolt of fear ran through my body. After I had figured out that it was my sister behind her mask I had completely forgotten about the cameras filming everything we were doing. Terror gripped my heart as I thought about how many people might eventually watch my step-sister and I naked together as she sat on my face.

The realization might have worried me, but Helen wasn't going to let that stop her from enjoying my tongue. She rocked her hips back and forth, grinding her pussy against my tongue and pressing her hips down a little more. Her hands pressed mine into her tits even more, trying to encourage me to pleasure her once more.

It took a moment, but I eventually started to eagerly lick her again. Helen's moans were too sweet not to want more of them, and despite my initial terror at the idea of being recorded with my sister it was starting to become an exciting concept. With her mask on no one would automatically know that she was my sister, and so the idea of people seeing me eat her out got alluring in how depraved it was.

With my motivations renewed I licked her with all the skills Sofi had taught me. My tongue ran up and down her pussy, pressing in and searching out every sensitive spot. Helen rewarded my dedication to her pleasure with loud moans of delight. I continued to squeeze her tits as they bounced with her rocking, and she sighed out in heavenly bliss.

When she took her hands off mine I began to explore more of her body. Her soft curves were wonderful to touch, and I pressed my hands into every one I could find. Helen twisted and turned, leaning into my touch as she enjoyed the focused attention of my tongue.

After a while I felt her lean down and reach for my cock once more. It had been aching for more attention, and so when her gentle fingers wrapped around my length it throbbed in satisfaction. She quickly started to stroke me again, which felt amazing. I was hardly even thinking about Helen as my sister at this point, rather just as a sexy woman who was enjoying me as I was enjoying her.

My enjoyment was increased dramatically as Helen leaned down even more and began to use her tongue to delight me. She licked up and down my cock as she continued to stroke me. I moaned hard against her pussy when I first felt her tongue flick against my shaft, not having expected the added pleasure. I quickly returned my own tongue to lavishing her with quick and deft flicks.

It soon almost became a competition between us. Helen and I seemed to be trying to outdo each other with how skillfully we could use our tongues on one another. I moved my tongue even faster over her dripping wet pussy, and she twirled her tongue around my dick in masterful coordination with her hand. When she lowered her tongue to my balls, I tried to match her by circling her clit with the tip of my tongue.

Our moans and cries of delight would have been loud and heavy if they hadn't both been muffled against each other. We worked tirelessly to give another the full attention of our lips and tongues. While I was trying to focus entirely on Helen, I still spared a few thoughts to what the other guests might be thinking. I wondered how much they were enjoying the sight of Helen's body pressed over mine as we teased each other with our mouths.
