My hand kept gliding up and down my shaft in slow, teasing strokes while Rita devoured the head of my cock with her mouth like she couldn't get enough.
She slurped messily, saliva spilling down her chin as she tried to swallow more of me.
Then she pushed deeper, gagging around my dick, her throat tightening beautifully as she smeared spit everywhere she could reach.
The heat of my sister's mouth was unreal, the kind of sensation that made my brain flicker in and out like a bad signal.
I felt dangerously close to cumming and l think she felt it to, so she pulled back, as if telling me that making me cum with her mouth was a line we shouldn't cross as siblings.
"You're lubed enough, right?"
I smirked. "Yeah."
The mess she'd made on my cock made stroking myself feel unbelievably good.
Jerking off with that mix of my sister's pit and my precum had my climax clawing its way up with violent urgency.
I moaned softly, meeting her eyes. She never looked away, not even for a heartbeat. Her eyes were filled with pure, undiluted lust and something else too. Pride, maybe.
She squeezed her thighs together, trembling, her smooth ass jiggling right in front of me as she tried to hold herself together. Watching her shake like that at arm's reach only made me hornier.
Then she did something I didn't expect. She couldn't stay still anymore—she spread her knees wider, sliding a shaky hand between her thighs and reaching for her throbbing slit.
She cupped herself gently, letting her middle finger slip between her folds and trapping it there tightly between her drenching lips.
[Rita's Affection has reached 49]
It wasn't the only notification. My phone kept buzzing—comments and gifts flying into the live.
Rita looked at me pleadingly, her hand perfectly pressed against her quivering sex as she let out a soft moan. I stroked myself faster, my hand slurping obscenely along my cock.
Her quiet breaths turned into sharp, needy whimpers as she began sliding her finger in and out of her slit. My sister masturbating while staring straight into my eyes was the hottest thing I'd ever seen.
Soon she was thrusting more urgently, adding a second finger into her smooth, shaved pussy.
Her pace became frantic, twisting her fingers expertly against her g-spot. Then her pussy clenched hard and a sudden, hot torrent of liquid burst out of her, splashing across her legs and soaking the sheets.
"A-ahhhh!" she cried. "Oh my god, I've never cum so hard in my entire life!"
Gasping, she quickly shifted, lying on her back with her legs spread wide, furiously rubbing her clit with her palm.
Almost instantly her moans rose again, and her pussy convulsed before unleashing another searing stream, spraying straight across my cock and chest.
Her hips bucked uncontrollably, pulling her pussylips open and showing me her velvet pink labia as fresh jets of her cum squirted across me with each thrust of her fingers.
She lifted her her ass off the bed, balancing with her feet and her back as she grunted like an animal, her eyes fluttering and rolling back behind her mask, her orgasmic juices spraying wildly at me.
I was dripping with her squirt, the intoxicating scent of her slick juices making me stroke my cock even faster.
After several long seconds, her orgasm finally began to fade, her squirts weakening into smaller, trembling spurts as she slumped back onto the wet bed.
[Rita's Affection rose to 57]
[Congrats, Host! You've completed the tutorial quest]
[You shall be rewarded]
I barely registered the message as I was too close to cumming myself.
It didn't take long. My orgasm tore through me, and I grunted as thick ropes of cum shot out, splattering across Rita.
I expected her to be annoyed, but instead she got back on all fours, opened her mouth, and welcomed my cum with her tongue, swallowing like a good girl.
My hips jerked as more hot streams pulsed out of me, each landing with soft spatting sounds on my sister's face.
I shivered and gasped as my climax subsided, cum still leaking down my shaft. Rita leaned closer and licked all the cum off my cock without hesitation.
And she slurped like she enjoyed it.
That's when l realized my sister truly had a slutty side she always hides.
It made me wonder how many cocks she'd tasted with that cute mouth of hers.
She pulled off my cock with a wet pop and slurped up the leftover cum around her lips before reaching for her gown and draping it over herself.
Then she walked over to her phone to say goodbye to her viewers.
The comments were going crazy—over six thousand, flowing nonstop.
[God, that was hot.]
[The guy is covered in her cum, dripping from his chest to his feet.]
[I want a gal who can squirt like her!]
[Haha...too bad you'd never made a gal cum before @badboy223]
[Are you two gonna fuck? Please say yes.]
[Take all my money! I'll gift a thousand dollars if you ride his cock!]
Rita gave a fake smile, clearly seeing her channel was on fire, but then she said her goodbyes, and ended the live.
Then she looked at me, her expression twisting from the fake smile to disgust and anger.
"You are sooooooo fucking dead, Mark!" Her hands were on her hips.
"Wait—what?" I raised a brow.
"Do you even realize what we just did? Oh my god! If someone recognizes us, I'm done for. My reputation at college will be ruined. My life will be over. People will judge me as— I don't even know!"
She ran a hand over her messy blonde hair like she was trying to think.
I honestly didn't get why she was freaking out so much. She already had plenty of naughty videos online. If she was scared of judgment, she shouldn't have gotten into adult streaming.
"I don't get it. We were wearing masks. Nobody's gonna—"
"Stop talking." Her tone cut sharp.
"…Right."
I grabbed my boxers from the floor. At least I'd passed the tutorial. I really didn't need to stay and deal with her meltdown.
As I pulled my boxers on, my cock finally soft, I opened the door, only for Rita to speak again.
"There are people who know about my OnlyFence," she said quietly, worried. "People who also know me in real life. They'll figure out it was you."
…Yeah, if that was true, she had a reason to panic. We could go viral as incestuous siblings. That'll be pretty bad.
But who could it be?
I figured even if l asked, my sister wasn't going to tell me, so I just walked out, closed the door, and headed to my room.
That was something to worry about some other time.
For now, l had to see my system rewards.
