Scott rushed to his sister's room after hearing a loud noise coming from it. He hoped she hadn't gone too far and hurt herself. He pushed the door without knocking.
Becker was standing in the middle of the room, looking at a broken machine on the floor. Scott had no idea what it was.
"Are you okay sis?" he asked, more shaken than her.
She turned around, looking a little angry. "Scott, how many times do I have to tell you to STAY OUT OF MY ROOM."
He hadn't noticed at first, but she was in rather lightweight clothes—a pair of panties and a loose t-shirt was all she appeared to wear (she still had her spike bracelet though). It was understandable that she didn't want him to see her like this. Still, he couldn't resist ogling at her bare legs, gazing up from her feet to her thighs.
Becker's face reddened. "OUT!" She yelled while she pushed him towards the door, slamming it in his face once he was back in the corridor.
Scott shrugged, wondering why her reaction had been so strong. It was to be expected though, she had been very clear about him not entering her room without being invited.
He went on with his day, continuing his book about dinosaurs, and the altercation he had with his sister quickly disappeared from his mind. When, a while later, he received a text from Becker, he didn't think it was related.
Can you come for a sec?
A little annoyed to have to stop his discovery of the great Sinraptor, he leaved his room and went once again to his sister's. At least now, he was invited.
When he knocked on the door, Becker only answered after a long silence. He walked in.
The weird machine was no longer in the middle of the room, nor was Becker. She was sitting on the side of her bed, in the same clothes as before.
"Did you want my help with something?" Scott asked.
"I want answers."
"About what? I can probably help you with your homework, especially if it's about dino-"
"That's not what I mean," she cut him, and sighed. "Earlier. Were you checking me out?"
Scott became more confused. "I… went to check on you because I heard a loud noise? Yeah?"
Becker facepalmed. "This is not what checking someone out means… You were looking at my legs, right?"
"Uh, I guess?"
Becker paused, her face slightly blushing, not sure what to say next.
"Do you want me to apologize for that?" Scott asked her, a little worried he had hurt his sister. Since she didn't answer, he continued. "Look, I didn't really do it on purpose, my eyes just wander and you were in the middle of the room, and…"
"It's fine," Becker said suddenly. "I'm not mad or anything, I just wanted to make sure of something."
An awkward silence followed. Scott was standing in the middle of Becker's room, wondering what the point of the discussion was, and Becker was trying to understand how much he was aware about all of this.
"You- you can check my legs more if you want."
Scott's mouth opened slightly from the surprise, but he didn't say anything. Becker's legs were still the same, and after looking for a few seconds, he realized there was not much to see that he hadn't seen. But he probably had to say something. "They look… smooth?"
Becker blushed slightly more. "Do you want to touch them?"
Scott shrugged. He didn't especially want that, but since she was offering, it was an opportunity that would probably not happen often. He sat next to his sister on the bed, and she rotated to place both of her legs on his lap.
All of a sudden, Scott felt weird. As if the proximity he had now with his sister was different than usual, more awkward, but he couldn't put a name on it. He touched her calves with his fingertips, more focused on looking than touching. Becker shivered when she felt his fingers against her skin.
First, he moved towards her feet, stopping his fingers on the bridge while looking at her small toes. Then, he slowly went the other way, enjoying the softness of her skin, up to her thighs. They weren't especially large, but they weren't too skinny either.
Becker was breathing loudly.
"Are you okay?" Scott asked, suddenly realizing his sister looked unwell.
"Yes," she answered immediately. "Actually, no."
She fell back on the bed, placing her hands on her face, as if she tried to make the redness disappear.
"Did you pee yourself?"
Becker tensed up, looking at Scott's confused face. The way he was staring at the place between her legs was incredibly embarrassing. How clueless he was. It took her a tremendous effort to explain.
"It's not… pee…"
"Then what is it, did you drop water on yourself?"
Becker sat back up next to him. "Scott, have you ever masturbated?"
Suddenly, he was very self-conscious. "What? Uh, what if I have?" He squinted at her.
She rolled her eyes. "So you know how your dick gets hard when you're excited right?" she asked without any tact.
He nodded.
"Well, this is the same for me, except I have no dick."
Becker's heart was beating at full speed. She had no idea where this was going, and Scott made everything so much harder.
He looked at her, frowning, until something miraculously clicked in his brain. "Oh, so it means you're excited?"
Becker rolled her eyes again, trying to get her heartbeat under control.
"Did I… cause this?"
Becker didn't answer the obvious question.
"Does it mean you want to masturbate?"
Becker would probably have stopped here if she was thinking, but she didn't want to think. This had gone too far to start thinking now. "I guess it does."
"Should I leave you alone then?"
"…No. Stay."
Slowly, Becker started to remove her panties. Scott saw a few strings of glossy liquid linking the underwear and Becker's crotch. Most of all, he saw how wet it was on the other side.
He couldn't see her crotch itself though.
"Now do the same."
Scott swallowed, but he complied. First, he removed his jeans, and that much already meant that he could no longer hide his boner. Becker was obviously staring with interest. Then, he also removed his underwear, his hardened penis sticking out from between his legs. He sat back on the bed, trying without much success to hide his intimacy from Becker.
"What now?"
"I guess we can… masturbate together? I mean if you're okay with that, which is probably the case since you undressed when I asked you to."
Without waiting for an answer, Becker moved back on her bed, facing Scott, and spread her legs. All of a sudden, he had a good view of his sister's bare slit, as mysterious as it was intriguing. He moved to her, no longer concerned about hiding his own stuff.
"It's the first time I see… one." he explained.
"Me too you know. In real life."
More silence.
"So, should we just masturbate in front of each-other or were you thinking about something else?"
Becker bit her lip. There was something she had seen on internet and kind of wanted to try, but she didn't know if it actually felt good or was just one of the weird things they did in porn. There was no harm in trying though.
"I was thinking we could rub them together?"
"With our hands?"
"No, just… You place your dick on my cunt and hump against it." Her heart was beating even faster than before, and her face felt like it was burning. Scott wasn't in a much better state.
Slowly, he moved forward on his knees, and got veryclose to Becker's crotch. And then he stopped.
"How am I supposed to make them touch when your hips are so much lower than mine?"
Becker would have facepalmed if she wasn't so flustered. She simply raised her hips a little, and suggested Scott could spread his legs to lower himself too.
Suddenly, she sensed his penis touching her slit. It felt weird, but not in a bad way. Scott became fully hard when he felt his sister's most personal place against the underside of his shaft.
Then, he started rubbing. Becker instantly opened her mouth to breathe, immediately tensing up when she felt him push against her lips, spreading her wetness and pushing on her clit through her skin. Scott on the other hand didn't feel as good as his sister. Sure, the way his penis slid along her lips felt nice, but he couldn't help but think that masturbating with his hand felt better.
"Are we having sex?"
"No, we're just," Becker held out a moan, "masturbating together. If you had your penis inside of my vagina then it would be sexhmmmm."
Scott kept going for a while, listening to Becker trying to suppress her moans while trying to focus on his own sensations. If they had been building up for a while, now it seems like he had reached a plateau.
He stopped.
Becker looked at her brother, confused. "Why did you stop?" she asked, still breathing hard.
"I want to try something else." He moved back slightly, lowered his hips, and placed the tip of his penis between Becker's lips at a steeper angle.
When Becker understood what he was about to do, she tried to stop him. "Wait Scott, you can't-"
He was already halfway inside when she spoke, and didn't pay attention to her half-sentence. Immediately, he started thrusting, now feeling Becker's folds all around his shaft, providing much more friction and pleasure.
"Scott... anhh... you- you need to… anhhh… pull out."
"Why?" he asked, focused on his task, biting his lip.
"We can't… anhhh… have sex!"
She wanted to stop him, but it was like all of her strength had left her body. And her brother… her brother felt so great inside of her. The way he spread her insides, the way it sent shivers all around her crotch and up her spine, the way her climax was slowly building, it was just too great.
"Oh shoot!" Scott said when he climaxed, feeling ropes of his semen coming out of his shaft.
Becker widened her eyes when she felt the warm liquid swell inside of her. Her own brother had just came inside, and…
Becker reached her climax at the very moment she was starting to panic. She felt her insides tense and throb around Scott, as if they were pumping the love out of him. "Oh fuck Scott," was all she managed to say between two moans.
When Scott felt Becker's inside calm down, he removed his penis from her, and she collapsed on the bed. Soon afterwards, Scott's semen started dripping out of her and landing on her bedsheets.
"I'm sorry, was I supposed to do that inside of you?"
The question made Becker snap back to reality. She expected herself to panic but… surprisingly, she was calm. As if her orgasm had washed away her fears. "Not really," she answered, a smile on her lips.
"We're too young to have babies anyway right?"
Becker stared at his face.
"Oh god oh god, I'm too young to be a father! What about my lost childhood? And what am I going to say to Hailey and Kristine?"
Becker burst out laughing. "Don't worry dingus, I can probably deal with that. And besides, I don't plan on having children either, especially not with you." She stuck out her tongue.
"Hey! That's mean!"
Both of them laughed.
"So, do you think we can… masturbate together again sometime?"
Becker looked at her brother. It had felt good, way better than masturbating alone. It probably felt good with any other guy, but she wasn't sure she was ready to do it with a stranger or even someone from school. She had all she needed right here with her.
"Fine, but you have to promise not to tell anybody, not even Hailey. Especially not Hailey."
Scott looked at her, annoyed. "Sis, I'm not dumb."
Becker burst out laughing again, quickly followed by Scott, who wasn't super sure why they were laughing.
