Thans

As always, all characters over eighteen.

Things between me and my sister settled into a strange kind of normal after that first mostly naked online video-chat come mutual masturbation session.

Every week, without fail, Kate and I would get naked in front of our computers, get ourselves off while watching the other, then we'd spend a few hours talking about anything and everything.

I don't know how she felt about things, but I wasn't overly keen to risk doing something stupid and fucking things up if I went to see her in person. Honestly, she might only have been okay with what we were doing because of the safety of being in a completely different suburb to me.

I found out how wrong I was about that a few weeks later.

It was a Wednesday, and everything was going as normal for me. I was doing some study for my uni course, struggling to understand the dense textbook, when my phone buzzed and played the notification sound.

I ignored it, because I knew that I'd never get back to the books if I checked on the notification.

It went off again.

I ignored it again.

But the ten subsequent notifications that went off over the next twenty seconds made it obvious that whoever was messaging me felt that it was important enough to spam messages.

I picked it up and frowned when I saw that it was Kate messaging me.

⟪Help! Something's gone wrong with my setup, and I can't get it workign!⟫ she had written. It was quickly followed by, ⟪Please! I know you're home! I texted Mum! Answer me! Look at your fucking phone! Check! Your! Fucking! Phone! Now! I need your help, Nick!⟫

I sighed. There was no way that I was going to be able to ignore her any longer. It probably wouldn't be long before she got Mum to come and knock on my door.

I took a moment to mark my spot in my textbook before I started to compose a reply.

⟦You can calm your tits now, Kate,⟧ I sent. ⟦What's gone wrong?⟧

⟪Finally! And fuck if I know! You're the computer wizard here! Just get your ass over here and fix it!⟫

Her responses came in rapid succession, and I could

feel

her agitation through the app.

In response, I sent her a pair of emojis, ⟦👍🚗,⟧ telling her that I was on my way. Then I changed into some clothes that I hadn't already slept in and headed for the front door.

"Something's gone wrong with Kate's computer," I called out to Mum as I walked by the family room. "I'm heading over to see what's up."

"Okay!" Mum called back. "Make sure that she shows some appreciation for your help. I know how ungrateful she can be sometimes."

I bit my lip. If Mum only knew how thankful Kate was. And, of course,

how

she showed her thanks…

It was only a fifteen minute drive to get to Kate's place. She burst out of her front door before I had even put the car in park. She as already in her streaming outfit, which consisted of nothing more than a pair of booty shorts and a low-cut shirt.

"About time!" she huffed. "I'm supposed to be live in twenty minutes!"

"Keep your shirt on," I grumbled. Privately, I wanted her to do the exact opposite.

We shared no more words as we walked through her house and headed into her studio. Her monitors were in a slightly different position than I had set them up in, and they were still turned off, while the tower was flashing all its usual lights.

The problem was almost immediately obvious, as was the solution.

"You fucked with things, didn't you?" I asked without looking at her.

"No," she denied, her tone unconvincing. I turned and raised my eyebrows at her. She grimaced sheepishly and admitted, "I might have been trying out some new camera positions."

I shifted around behind her desk and took stock of the cables at the back of the tower. I unplugged the display cables from the motherboard's outputs, plugged them back into the outputs on the graphics card, then stepped around to the front of her desk and turned the monitors on.

"Problem solved," I said. Turning back to her, I gave her a fake-stern look and said, "Next time you want to change things, let me know, and I'll come help you out, okay?"

Kate had sagged with relief as the screens came back to life. Nodding, she said, "Promise, bro."

Kate then pushed past me and started opening OBS and other programs Suddenly, it was as if I wasn't in the room any longer.

"You know… maybe Mum was right," I chuckled. Kate glanced over her shoulder at me quizzically. Explaining, I said, "Before I left, Mum told me to make sure you show some appreciation."

Kate paused, frowning slightly, then turned back to her computer and opened an app that was a distinctive shade of Twitter blue. She typed out a quick message, then copied and pasted it into her Discord app, then stood up and turned to face me.

"I've told everyone that I'll be half an hour late in starting because of computer issues," she said. Then, she gripped the bottom of her shirt and took it off, leaving her in just her booty shorts and a sturdy pink bra. Those booty shorts were quickly slipped down her legs, revealing that she was wearing a pair of knickers that were the same shade as her bra.

My jaw dropped to the floor. Her body was fucking amazing when I was viewing it on a computer screen. It was absolutely other-worldly in person.

Kate smirked at my dumbstruck expression and put her hands to the sides of her breasts so she could gently bounce them side-to-side. "Mum thinks I'm an ungrateful bitch, doesn't she?"

"Not in so many words," I mumbled. I was surprised that I was able to form any kind of a coherent sentence.

"Well, I can't let her be right about that, can I?" Kate asked rhetorically. A second later, her hands were behind her back and she unhooked her bra, then let it fall to the floor between us. "Now, are you gonna get your dick out, or what?"

She didn't have to ask me twice. My pants were around my ankles half a second later.

While I started slowly jerking off, Kate took a step back and settled onto the bed she had set up to be in the background of her stream.

"You can cum on my tits, okay?" she offered. "Just try not to get any on my face. I won't have time to re-do my makeup."

"Why'd you tell them you'd be half an hour late, then?" I groaned. "You know how quick I finish sometimes. You could've told them five minutes and you'd have time to clean up and still be early."

"Who says I'm going to clean up? I was just gonna put my bra and top back on, and do the stream with your cum soaking into my tits," Kate said, a sultry grin on her lips. Then she added, "As for the time it'll take, you can just cum on my tits two or three times. Or as many times as you can manage in the next forty minutes."

Her hands came down to play with the straps of her knickers. She looked up at me and gave an apologetic shrug. "These are going to have to stay on, unfortunately."

"I'm fine with that," I grunted.

"I'm not," Kate responded. My hand stopped halfway up my shaft and I looked at my sister, confused by her words. She sighed. "I don't trust myself to stop at just letting you cum on me if I take them off. I find it hard to resist a dick at the best of times, so you waving that monster around right in front of me is fucking torture!"

Her words set me off. My cock bucked and pulsed in my grip as I blasted a load of cum onto my sister's chest. I was just barely able to keep her request in mind and aim my cock below her neck.

When I finally stopped cumming, Kate's chest was absolutely coated in my seed.

"Fuck," she murmured, her gaze alternating between my still throbbing cock and the state of her tits. "That's

so

fucking awesome to see in person!"

Feeling a burst of confidence, I straightened and said, "That's one. I reckon I've got another two in me in the time we've got."

Kate pressed her thighs together as a shudder went through her.

"You're really fucking testing my willpower here, Nick!" she groaned. "So hurry up and do it, then get the fuck out before I throw you down on this bed and fuck the life out of you!"

After all the conversations we'd had over recent months, I knew Kate well enough to know that she wasn't bluffing. I also knew that she had said the words so that it would be

my

fault if it happened tonight.

So, I resolved that I was going to do as she asked. I was going to jerk off on her tits another two times, then I was going to get back in my car and head back home.

My cock hadn't softened at all before I started stroking myself again. I watched and wanked as Kate brought her hands up to her tits and started kneading and mauling them, working my spunk into her skin.

"You seemed to like it when I called your cock a monster," Kate said. "You

do

know that you're hung like a donkey, right?"

"Kinda hard to miss," I snorted. "It's attached to me, after all."

"Yeah, obviously," Kate said, rolling her eyes. "But I don't think you know just

how

ridiculous your dick is. I've had a few boyfriends in the past who thought they were pretty big. You're

easily

bigger than any two of them

combined

."

"Uh… thanks, I guess," I said.

"And this!" Kate said, lifting her hands away from her tits and gesturing at the state of her chest. "It would've taken any one of them a month to cum this much! And you're saying you've got another two loads in the works? What kind of genetic freak are you?"

"Gotta say that I'm not overly fond of being called a freak, Kate," I frowned.

"In a good way, obviously," Kate said absently. Her gaze was fixed on her cum-coated fingers. Suddenly, she shoved those fingers into her mouth. After a long second of audible sucking, she let out a long, pleased groan. "Fuck! And you even

taste

good, too!"

That was the end of me for the second time in only a few minutes.

My vision darkened and, when I regained the ability to form memories, it was to the sight of Kate once again covered in a thick layer of cum.

I panted and, after an experimental stroke of my already wilting cock, I was forced to admit, "I might have overestimated myself. Two's my limit at the moment. Be at least an hour before I can go a third time."

"Disappointing, Nick," Kate said, though the tone of her voice betrayed the lie of her words. "We're going to have to work on your stamina, bro. It's going to take longer than ten minutes for you to fuck me properly. Lucky for you, I'm willing to let you keep trying until you get it right. We'll just have to set things up for when I'm not already booked for something else."

She glanced at my cock and frowned. "Nothing?"

"Not a twitch," I sighed. "Done. Empty. Kaput."

"Fuck," she complained. "Well, you'd better get out of here before that thing recovers, or I'll never let you leave. And, when you get home, make sure to tell Mum that I was

very

thankful, okay?"

"So? What was the problem?" Mum asked as soon as I walked through the door. She had used the back of the couch to lift herself up to turn and look at me.

"Nothing major," I replied. "Just a few cables plugged in wrong. She's back up and running already."

"She's lucky to have you for a brother, Nick," Mum said. "So, did she show a little appreciation, or do I need to have words with her about not taking you for granted?"

"It's fine, Mum," I sighed, my vision blurring as the sight of Kate's tits floated back to the front of my mind. I felt my cock throbbing back to life. As I quickly fled the room, I added, "She was very thankful."
