[M4F] Housesitting with my weird, girlfailure, NEET sister

"So why can't my sister do it? She's the one still living at home," I ask our mother over the phone, instantly regretting letting the words leave my lips. There were countless reasons it was a horrible idea, many of which either of us could have quickly listed off, but still so, so many more we wouldn't have even been able to quantify until after one of those inevitable disasters might strike.

After a healthy moment of hesitation chased by a deep, resigned sigh, mom finally replies, "Because if the house burned down, the only thing she'd think to save is her laptop? Assuming she'd even notice the house burning down around her to begin with."

Considering how much she and dad coddled you, I was honestly a bit shocked by how honest an answer that was. Despite you dropping out of college and refusing to get a job, the two of them had catered to your every need, so much so that you had basically atrophied as a human being. You didn't cook anything you couldn't microwave, god knows you didn't clean, you never left the house, and you were utterly incapable of so much as looking after our family home for a week while our parents took a sorely needed vacation.

And, well, if the house did burn down, there's no way you'd be able to even call 9-1-1, because that would require talking to a human being you're not related to.

"Okay, true," I concede, idly drumming my fingers along the back of the phone. "But is she going to be... weird about it?"

Another long pause ensues before mom finally replies. "She's not weird, she's just... confused. It's only for a week." Yep, that told me everything I needed to hear. Before I can rebut, mom hastily continues, "Listen, we'll talk more about it when you get here tomorrow. I've got to run and pick up your dad. Love you, bye!"

Confused, right. Before I moved out, you regularly asked about my masturbation habits, and wanted to compare notes about how often we each did the deed. Whenever I'd borrow your phone, I'd be greeted by a dozen tabs of questionable searches and the occasional sprinkle of incest hentai. To top it off, whenever I yell at you for being so creepy, you make the strangest fucking noises. One time you even bit your fucking lip. Suffice it to say, weird is the tip of the iceberg when it comes to you.

Well, one way or another, this was certainly going to be an interesting week. I just hope my old room is still something resembling how I left it... and that the lock still works. The only thing I know for sure is that I am not sleeping out in the open on that ancient slab of a couch.

Just to get it out of the way, I know the NEET thing comes with certain stereotypes, but I absolutely do not want any bad smells or poor hygiene so much as referenced in this scene. Your room can be messy, your appearance certainly doesn't have to be tidy, but your character needs to be clean, it's non-negotiable.

That aside, as the prompt implies, your character is going to see this little week long adventure as a way to get some dick from her older brother. You don't have to be a virgin or anything, your character could have maybe messed around with an online multiplayer buddy or whatever, but you've got a bonafide obsession with your brother that nothing else can ever scratch. The kind that's so obvious that everyone around us has taken notice, even if they pretend it's all one big misunderstanding.

Some things that I like: risky sex, riding, teasing, handjobs, oral, partially clothed sex, barebacking, banter during the act, and a little cumplay never hurt anybody.

Limits: Non-con, bathroom stuff, violence, blood, animals, foodplay, unrealistic anatomy, excessive pubic hair, and anything futa related.

Please no one line responses either, give me a couple sentences to sink my teeth into at least.
