Jake sat in the basement of his mom's place and watched TV. It was some dumb show about flipping houses or something, but Jake wasn't really invested in it. As he sat there he was swiping through a dating app, not really invested. He knew he was distracted by something, but he wasn't really ready to admit it even to himself.
After a while the show ended and another started about making pools for rich people or something. Jake took this as a cue to maybe stop halfheartedly trying to get laid and maybe go to bed. Who would want to sleep with someone who still sleeps in their mom's basement anyway.
"I'll just take a peak, see what she's been up to lately. We don't really talk that much, so its not weird or anything I'm just checking in", he thought to himself as he pulled up Instagram and navigated to a familiar profile.
It wasn't his real Instagram, he made a fake one a while ago to follow his sister so she wouldn't think he was seeing what she was posting. And man, did she post some stuff.
His sister, Megan, had a pretty decent following on Instagram. It may have been because she was an interesting person who posted interesting things, or it may have been because Megan is naturally thin and pretty with natural H-cups and a nice, round ass.
All of Megan's posts are of her in various states of undress: usually she's lifting her shirt, or wearing just a bra, or some lingerie, or a bikini. Jake's favourites were the videos though. Most of them involved Megan wearing no bra and bouncing her big tits. Walking around and videoing herself, sitting still and making them move on their own, jumping up and down, etc. These were basically the only thing he watched anymore to masturbate.
As Jake sat on the couch he thought for a moment he should get up and go to his room down the hall. The excitement of doing it right then in there was tantalizing though: while Jake definitely did not want to get caught jerking off to his sister's Instagram in the basement living room, part of him found the risk kind of... heightening.
Jake covered himself from the waist down with a blanket that his sister used when she sat on the couch and pulled his cock out of his sweatpants. He spit in his hand and slid it under the blanket and started jerking off with one hand, while browsing his sister's pics and vids with the other. He was close to finishing while watching a video of Megan pushing her boobs together under a tank top and moving them around when he heard a small soft voice behind him.
"Jake?"
A jolt of fear and shame shot through Jake as he tried to inconspicuously lock his phone screen while stuffing his cock back in his pants under the blanket. Knowing it would be weird if he took too long to react he turned his head towards the stairs behind him.
Megan stood on the last few stairs, staring into the living room area with a bemused look on her face. Jake couldn't figure out if she would have had an angle to see his phone, she definitely couldn't see that he was jerking off from there, as the back of the couch was in the way.
"What're you watching?", Megan said with a teasing tone to her voice.
"Huh?", Jake said, trying to feign ignorance.
"Is this that dumb show were they make pools and its always like the same thing? Why are you watching this?", Megan asked, practically laughing.
Jake almost sighed in relief. Of course she was reacting to the dumb show.
"Oh ha I dunno, just kinda zoned out I guess."
"K well I wanna watch TV and I don't want to watch this shit so...", as she said this Megan came into the living room and sat on the couch beside Jake. Time seem to slow down for a moment as Jake noticed Megan was bra-less, and her boobs bounced almost excitedly in her tank top with each step towards him. Second, she was wearing no pants, just a pair of blue cotton panties. She slipped onto the couch beside him and cuddled up close, pulling the blanket partially onto herself.
"Make room for me Jakey", she said softly as she squeezed in. Jake tried to move over but there wasn't a lot of room on the loveseat and as he tried to adjust she snuggled in closer to him. He froze as he felt the sudden weight of her large breasts pressing against his side.
"Give me the remote, you clearly can''t be trusted here."
In a daze from her unexpected closeness, Jake handed her the remote.
"Wow, can't believe that worked", she said as she looked up at him. She then shifted slightly and settled into him more, so that her head was resting on his shoulder. She started fussing with the blanket a bit and Jake looked to see what she was doing, when he cursed internally. There, plain as day, was a wet spot on the blanket from where his spit covered cock had been rubbing. Megan looked at it for a long moment before looking up at Jake, smirking when she saw how red his face was, and then looking back at the TV.
As Megan changed channels she blew air between her lips, making them flap slightly in a silly way. Jake's mind was racing trying to figure her out. She had never been this physically affectionate with him before, at least not since they were kids. She seemed to suspect something from the wet spot and the knowing look she gave him, but that didn't change anything? She still wanted to snuggle him on the couch under this blanket that she seemed to know he had been jerking off into?
"This looks familiar, do you know what movie this is?", Megan suddenly asked. Jake snapped back to reality and try to focus on the screen.
"Why don't you just read the description in the channel list?", Jake asked.
"It just says... 'Movie Night'... like, yeah, thanks. I'm pretty sure this is an old classic movie but I can't think of what the title is...", as she said this she absent mindedly pulled out her phone and opened Instagram. Jake's heart started beating quickly as she opened up the search bar and started typing in some text. Jake struggled to read it, as her body was mostly in the way.
"Do you want to watch... whatever this is?", she looked up at him curiously as she asked, still typing away in the search bar.
"Uh, yeah sure. Are you going to just play on your phone the whole time?"
"Not the whole time...", she said and smiled up at him. He saw her phone screen and felt his heart leap into his throat. She had pulled up the page of his Finsta.
"No followers, follows only me. Must be someone I know. Someone who doesn't want me to know they follow me...", she said this quietly, almost to herself, but her tone seemed a little theatrical. Jake was speechless as he watched her.
"Seems like... someone who wants to jerk off to me and made an account just for that. What do you think Jakey? Would you ever do something like that?"
As she said this she turned the volume up on the TV slightly and put the remote down between Jake's legs, pulling her hand back slowly from the remote, letting her fingers drag across her brother's legs. Jake was frozen in shocked surprise.
"Did you want me to find out? Is that why you were doing that in here?", she whispered as she leaned towards his ear. Jake shuddered involuntarily.
