They lay sprawled out on the bed for some time, neither one of them saying anything, enjoying their post-orgasmic endorphins. “I need to clean up,” Matt said when he finally got the willpower to escape his bed.
“I can clean it for you,” Ellie offered once Matt pulled it off his cock.
“Are you sure?” Matt asked.
“Yeah, I got it,” Ellie said. She pulled back on her shirt and grabbed both of their sex toys. I will bring it back later tonight.” Ellie said as she walked away. She could feel Matt’s eyes on her ass as she walked away. She got the sudden urge to show him her ass, so she pulled up the shirt and let him get a peek at it for a few seconds before dropping it down again as she stepped out of the room.

The next day when he came home from school Matt saw Ellie wearing a tight shirt that exposed her midriff and tight denim shorts. He had never seen her dress like that before. She found every excuse to show off her body or brush past Matt. She kept him in a constant state of arousal, and he couldn’t wait until he had time to masturbate later. He hoped that they would masturbate together again. He still couldn’t believe what he and Ellie were doing. The only relief he got from her constant teasing was when she left to go to the mall with her best friend.
Matt eagerly awaited Ellie in his room that night, and it wasn’t long before she gently knocked on his door and let herself in. She wore a sheer nightly that clung to her body, her nipples poking through the soft material. She sat down in the same spot as the night before.
“Do you want to have a movie night?” Ellie asked him.
“Sure,” Matt said, thinking that nothing was going to happen between them.
“What do you want to watch?” Matt asked her.
“This,” Ellie said. She handed him her phone and Matt was shocked to see that she had a porn video up. It was a brother-sister video. “Is that ok?” Ellie asked.
“Yeah.” Matt gulped.
Ellie sat next to him, their sides touching, and then started the video. In it, the cute little sister bounced into her brother’s room while he was lying down and proceeded to seduce him by caressing him while they talked. Her tight tube top and skirt barely even hid anything from her brother. She ended up touching his erection and talking him into letting her see it, which led to her starting to give him a hand job.
Matt got so turned on at the thought of Ellie doing that to him that he started to slowly stroke himself through his shorts. He looked at Ellie out of the corner of his eye, and he could see that she was beginning to rub herself too.
As the video intensified and the girl in the film started to suck on her brother’s dick, Ellie slipped her hand inside her shorts. After a couple more minutes of them touching themselves, Ellie began to strip out her clothes. Matt did the same, and they both lay back down completely naked. Matt couldn’t believe that he had his little sister naked in his bed. Matt sneaked glances at
Ellie, loving the way her whole body writhed as she rubbed her pussy and played with her perky tits. Out of the corner of his eye Matt kept catching Ellie watching him stroke himself. Having his sweet little sister watching him while he jerked off sent a thrill through him, and he found himself speeding up. Ellie matched his speed, and as they approached their orgasms, they forgot about the video they were watching and instead focused on one another. They glanced into each other’s eyes in an intimate stare. The desire in Ellie’s eyes was so powerful. He wanted so badly to kiss her, but he didn’t know if that would be pushing things too far.
Ellie closed her eyes as her moans of pleasure got louder, and she started to hump against her hand as she came. Matt groaned and started to cum as he watched her in the throes of her orgasm. His orgasm came so suddenly that he had been pointing his cock towards Ellie and didn’t have enough time to point it away from her, so his first couple of loads shot out and landed on her lower stomach and thighs. Matt got so turned on knowing that he came on his little sister, but he felt bad because he hadn’t meant to do that.
They lay in bed together, catching their breath.
“Did you cum on me?” Ellie asked.
“Sorry, it was an accident. I can get something to clean it,” Matt said as he started to get up.
“Don’t worry about it.” Ellie pressed a hand to his chest to get him to stay in bed. She reached down and grabbed her panties. She used them to wipe the cum off her. After laying together for a bit longer, she got out of bed and dressed.
Matt tried to apologize again for cumming on her.
“It’s ok. I liked it,” Ellie said. Before Matt could ask her more about it, she walked out of his room.

Nearly every night after that Ellie would join him in his bedroom after their parents were asleep. Now they always masturbated fully in the nude. Sometimes they would use their sex toys, and other times they would just use their hands. They would watch each other but would also often watch porn together. They took turns choosing the video.
After a couple of weeks of their routine, there was a night when Ellie seemed like she had something on her mind. “What’s wrong?” Matt asked, hoping that everything was ok between them.
“I was wondering if tonight, we could try and do it for each other,” Ellie looked down at the ground as she said it.
Matt’s cock twitched at the thought of them touching each other, and he wanted to say yes instantly, but he made himself stop and think for a moment. “Ellie, I would love that, but what we have been doing together has already been pushing things that we should do together. I just wouldn’t want to take advantage of you or do something to hurt you,” Matt said honestly.
“There isn’t anything that you could do to take advantage of me. How about we use the sex toys on each other. If we do that, then technically,” she said the word drawn out, “we are not touching each other, so it’s not like we are going further than we already have,” Ellie said.
Matt knew that it would push things to the next level, but his curiosity and arousal won out. “Ok,” was all Matt managed to say.
She handed him her vibrator. Matt felt overwhelmed. Over the last few weeks, he had gotten to see her masturbate countless times, so he had some ideas on what she liked, but he wasn’t sure where to start. He started to gently press it along her folds, not trying to be too rough. After a minute of him probing around and not knowing how to start, Ellie said, “Hold on.” She grabbed his hand and pulled it up towards her mouth, and she began to lick and suck on the vibrator. Matt’s cock twitched at the sight of her sucking on her vibrator. He imagined what it would feel like to have her suck his cock. She started to get into it, bobbing her head back and forth on it. When she pulled it out of her mouth, it glistened with her saliva.
“Now it will feel better,” Ellie said. Matt went back to exploring her folds with the toy, noticing how she relaxed on the bed and her breathing changing that she was starting to enjoy it more. He pulled the toy from out between her pink lips and started to rub it against her clit. Ellie let out a moan at the contact, so Matt did it again the same way.
