[M4F] [M4TF] Catching My Sister Masturbating

Things were supposed to be getting better at this point of my life, right? Graduated college with a decent degree, scored a pretty good work from home job... But this damn economy...meant that there were some sacrifices to be made. So, here I was, living at home, instead of living on my own. I guess it wasn't so bad- Dad charged a lot less for rent than any landlord was going to. Even if it meant dealing with living with family, it could be worse.

​

Today had been one of our monthly 'in office' days, and frankly, I ran out of there as quickly as I could. Made some excuse about a family function I needed to attend, just enough of an excuse to get out a few hours early. I sped home and practically ran up the steps to the house. I was hoping for some much needed alone time- I knew Dad would be working late tonight and I thought my sister would be out of the house too.

​

It was quiet enough when I walked in. I paused for a moment, listening for some hint that you were still home. The usual- music or some TV show or movie floating out from your room. I still wasn't quite sure why Dad was letting you do what you wanted- him being...well... the way he was about a lot of things...I would have thought that you still being at home with no job or prospects would be an issue. But he still let you live here- you were still his flesh and blood, regardless. But...most days it seemed you just lounged about- "looking" for work.

​

Today, though, I was met with a much quieter house. As I walked into the entryway, I thought I heard something...but it sounded...was that a Moan?

​

I followed the soft noise down the hallway towards your room. Your door at the end of the hall was cracked a few inches, and clearly the sounds I'd heard were coming from there. My mind was racing with what was going on. If you managed to sneak someone in, Dad was going to be furious...

​

But when I approached the room and peeked inside- I was met with just one body. Yours. My Sister...

​

Like I'd never seen you before. Dressed in lingerie, makeup and hair styled, fucking yourself with a dildo...I could hardly believe it. And I could hardly believe how hard I was feeling myself get.

​

I couldn't stop myself- I indulged in watching for a minute or so. It was intoxicating to see you like this. I had no idea you were so...well... I decided that watching wasn't enough. Dad wouldn't be home for hours...

​

So I pushed the door open, stepping inside with a smile on my face. "Hey, Sis. What's going on?" I ask in a playful, teasing voice, standing just inside the doorway of your room, eyes trained on you.

Pretty standard premise! Walking in on my Sister enjoying a new toy at home.

​

Maybe filming for OnlyFans or something like that? Maybe we just live with a very conservative Father and so he'd be furious to know you were doing this? Maybe you're Trans and he'd be horrified to know what you get up to under his nose? Maybe you're not a Sister- Could fill this role with a Mother, Cousin, Aunt, Stepfamily...Lots of ways to play it out!

​

Looking for a consensual scene here. Don't really want this to be a 'forced' situation. More of a mutually beneficial one. A bit of surprise to see me at first, but we wouldn't want Dad to find out, right? You'll do anything for me to keep your secret, yadda yadda.

​

Would love to brainstorm more if you've got some ideas. I'd love to hear them. Definitely want to flush things out before we just jump right in. Include your kinks and limits in your first message so I know you read all this.

​

Looking for literate, descriptive writers. Less interested in overall post length, just looking for actual interest in setting the scene.

​

Biological Females & Transgender characters all welcome.

​

Some of my kinks that could work in this scene include spanking, rough sex, oral, anal, risky sex, sneaking around, cheating, 'hold the moan', public sex, mutual masturbation, being watched/watching, toys, dub-con, dom/sub dynamics, collars/leashes, and lots more.

​

Limits include scat, vomit, sounding, being topped/pegged, animals, kids, blood, death, other platforms besides Reddit. If it's not on the limits list I'm probably up for discussing it!
