Turns out, Rita was fucking famous on the adult OnlyFence platform. She had a lot of videos of her playing with her tits or rubbing her clit.
However, she had never made a video with any male, and her fans had been begging for that in her comment section for months now.
Some of her fans were sick and tired of the same masturbation videos of her, so they decided to unfollow her, and only a few loyal ones remained.
But still, her channel was plummeting, and fast. She was losing relevance despite being a young and smoking hot streamer.
I learned all that through reading comments from most of her previous posts.
Honestly, I never would've thought my sister was such a slut, especially considering she always acts all high and mighty with me while she masturbates for strangers online every night.
With only a boxer, no shirt, and a balaclava mask on my face, I walked out of my room. I made sure Mom wasn't anywhere near, and I was glad she must have already fallen asleep in her room.
I walked toward Rita's bedroom and twisted the doorknob open.
She was in the middle of a live stream when I got inside, and I saw her gasp in shock while looking at my side.
She opened her mouth to speak, or maybe to insult me, but I shushed her and put a hand over my lips.
Then I walked toward her bed where the camera was filming her sitting on her bed with her legs stretched wide while she exposed her sex to her fans.
"Care if I join you?" I muttered, trying to make my voice appear hoarse.
Who knows, maybe someone might recognize me through my voice online—you never know.
I watched my sister grit her teeth. "W-what the hell!! Get the fuck out of my room, you creep!!"
I stopped at the edge of her bed. "Continue your thing. Don't mind me. Act like I'm not around."
I was holding my phone in one hand, and I could see the live video of us from my phone. People began sending comments:
"Who's that guy?"
"Gosh… did Rizzybae finally decide to bring a man into her videos?"
Yeah, that was her streamer name. Rizzybae.
Rita closed her thighs together and gave me a death stare, pointing a hand at me. "You're intruding on my privacy!!"
"Pretend I'm not around." I repeated. "You've always treated me like I don't exist anyway!"
I began to rub the tent of my boner in my boxers.
Her mouth widened. "What do you think you're—?"
I gripped the hem of my boxers with my free hand and slowly began dragging the material down, exposing my blood-engorged shaft to my sister and her fans.
The look of shock on her face was indescribable.
My cock wasn't the biggest, but it was surely thick and strong, and I was proud of its head. It was huge and shaped like a mushroom. An average girl would struggle to suck it into her mouth.
My cock twitched repeatedly as the dragging material of my boxers sent delicate sensations up the shaft and into my aching groin.
Rita gave me a "what the fuck, dude" expression, but I saw her gaze lower down to my groin.
She stared at it for a few moments, then she stood from the bed and pushed me.
"Go out!!" She pointed to the door.
[Rita's Affection rose to 34 after seeing the host's hard cock]
I was surprised how her Affection was rising, yet her reactions were totally different.
Could it be she was way too proud to admit she wanted to see more of my cock?
I don't know if I could've done this under normal circumstances, or if the system was just fleshing out all the desires I'd wanted to act on for a long time but kept hidden, but for now, I felt like masturbating in front of Rita.
I wasn't going to masturbate to her online videos like most of her fans.
My phone kept buzzing with messages from her comment section.
[Is that scripted?]
[If they are acting, they must be really good actors. It's not every day you see porn that doesn't go straight to fucking!]
[Keep it hot!! I've tipped some cash!]
Dings of gifts echoed as some of her fans already began tipping more cash.
Even the viewer count was increasing, reaching almost 3,000 people now.
I leaned toward my sister's ear so only she could hear. "Listen… I just want to jerk off to the real thing, and you'll also do your thing. Can't you see your fans are loving this? Wasn't your channel falling down because you had no guy to act with?"
I coukd see a look of shock on her face, wondering how l knew about that. She then grunted, gritting her teeth, her body dangerously close to my hard prick. "My fans and I are none of your business. Get out before I scream!" she whispered back at me, the harsh kind of whisper that felt like a scream.
I had to push her further. "Well… should I expose your username to Mom and show her all your slutty videos?"
Her breath caught, and I saw her stiffen up. "You wouldn't dare."
"What makes you think l wouldn't?" I shrugged. "Let's do this once and nobody gets in trouble."
She breathed. "Are you....blackmailing me?"
"If thats what you like to call it, then yeah. I'm blackmailing you. What are you gonna do bout it?."
My heart was pounding though l had to keep a calm front. After all, my quest was to "tame" her.
She growled, but dared not say anything back. I took that as a 'yes' to continue.
With only a few inches between us, I could feel her breath quickening. She was loving this than she was letting on. Her legs quivered, giving her trouble at maintaining her composure.
I stared down at her breasts, and damn, seeing them up close, my sisters breasts were one of a kind. Her nipples were small dark buds, standing erect and hard like ripe blackberries.
It took me all my will not to latch out and suck on them. I mean, I'd only told her l wanted to just jerk off in front of her.
I pushed her slightly and she fell onto the bed, then with a serious tone, l told her to watch me jerk off. She looked surprised about how l even got to say that in her face without shame.
Now, without the confines of my boxers, my taut shaft raised itself up dubiously, oozing precum down its length which carelessly traced the paths of my extruding veins.
I used my fingertips to smear the obscene amount of precum leaking from the tip, spreading it over the swollen head and along the pronounced ridge.
Then I brought my fingers to my mouth, wet them, and wrapped them around my shaft just beneath the head—squeezing slowly, milking another bead of sweet, warm liquid from the slit.
I caught sight of my sisters nipples hardening more shamelessly. Her hands moved on their own, kneading her breasts as she sucked her bottom lip between her teeth, eyes locked on me with a hungry, expectant look.
Seemed she was just as horny as l was.
The feeling of jerking off in front of my slutty sister and over 3,000 of her fans was hot.
My gaze brazenly caressed her heaving tits and the face she hid under a pink mask as I began to slowly pump the head of my cock with my precum-slickened hand.
A faint squelching sound could be heard throughout the room with each wet pump. Rita gently quivered at her core as if a chill had passed through her.
She was reacting to seeing my cock just like the slut she was. I watched her try with her entire being not to display outwardly the feelings she was having toward her brother's cock at that moment, but the trembling of her body made it fairly obvious that she was restraining herself to pounce on me and get a feel of it.
She lay there on the bed, close to me, watching me jerk off without complaining anymore.
I became bolder and stroked my cock harder in front of her.
[Rita's Affection has reached 41]
Her Affection was rising nonstop, and it only made me bolder. I was going to pass this tutorial quest no matter what.
I smirked at her. Her eyes met mine briefly and I could tell she was visibly embarrassed by herself for feeling so horny in this situation. I kept stroking myself, never breaking eye contact.
She began grinding her thighs together ever so slightly.
I decided to push my luck.
"Would you please—" I paused, and rephrased my sentence. "Come and lube me up."
If l was taming her, there was no need for me to speak like I'm begging her.
"What?" she echoed.
"With your mouth," I added. "Make my cock slippery with your saliva."
The look of shock on her face was delicious to savor. She was shocked beyond belief at my request, yet somehow, there was curiosity in her eyes.
She got on her hands and knees, crawling toward the edge of the bed, then glanced at my cock—only inches from her lips.
I could feel her soft breath, and it sent delicious golden shivers down my spine.
Her eyes looked up at me through her mask, and I stared back through the holes of mine. The view was insanely hot.
And then, without hesitation, she flicked out her tongue and gave a soft lick along the shaft before opening her mouth wide and taking my massive crown-shaped head between her lips.
My toes curled in pure ecstasy. Her mouth was impossibly hot and velvety soft.
