[M4F] Taboo—So Forbidden And… So Impossible To Resist
Everyone has that point in their life where their mind goes to places it shouldn’t. It can be subtle like a passing thought, but once there… It’s so hard to forget—just a split moment, rippling with irreversible might.
The wrong, the forbidden should be so easily discarded. However, no matter how much I try… I can't… I just can’t get my sister out of my damn head!
It started at a day like any other, with me scrolling through my phone; well, doom scrolling to be precise. The time where you let your thumb do all the work and just absorb whatever appears on the screen without much thought. Maybe not the most glamorous, but we all have been there, did that sort of thing, right? Now, I have no idea if it's the same for women, but every once in a while… Certain pictures bring thought back to your empty mind—not anything of value, hell, even now I'm being roundabout about getting horny. Yes, I mean that every once in a while I see a girl who makes me pause to shamelessly ogle her pictures.
I know. I know. Being such a horn dog is more a teenager thing than a freshman's in college… But come on, can a guy not be a perv every once in a while? Girls post such revealing pictures for a reason, so the least I can do is admire them properly. The thing that bothers me, however, is who became the target of my internet debauchery: My Own Sister.
The first time was a simple mistake, me catching sight of a bikini-clad body and looking over its every single inch. After all, with how thin the straps were and the way the design did nothing to hide the curves, it was a crime to leave it alone. “Such a shameless girl.” I thought to myself, even when I felt my pants growing stiffer by the second. For whatever reason, that girl alone tugged on my senses worse than any other, but just as I scrolled up to see her face… My heart dropped to my stomach. There it was, a smile I couldn't forget—the same one that greeted me every day before its owner went away to college—one, belonging to my older sister. Her features were on full display, so familiar yet so strange, almost… Beautiful.
Of course I knew my sister was attractive. I mean, when you have all of your friends asking if she's home as they come over or give a few too many comments about her appearance, it's obvious. They even teased me about how lucky I was to see her every day, hinted at things which made me fight them on repeat. Sure, you find her attractive, but me? Her brother? I could never; or so I believe until it happened. Hell, how could I even accept lusting over my sister? Was it the distance that made me look at her in a new light? Pure confusion? Fuck! I just don't know! And worse… I can't stop staring at more of her pictures!

As you can see, we have someone who found themselves helpless with their own thoughts. On one hand bewildered, but on the other… Too indulged to stop using his own sister as his biggest guilty pleasure. To him, each day is a hell, yet every time he still goes to her profile, hoping she would post another picture; revealing or not, he's starved for her beauty, perhaps even addicted.
And this is exactly what I want to explore—the twisted emotions, tension, fall into obsession, and perhaps more heartfelt aspects. The current point is pretty open ended, so we can take it in a number of ways. Maybe his sister is about to come home and feed his addiction in real time? Maybe the college he attends is the same as his sister's and he will have to face her, along with all the guys who would try to get her first? Just maybe… He would even create a take account just to text her, exploiting the anonymity of the internet to be brave in ways he wouldn't otherwise?
There's just so many options to explore and combine, so if you too would like to explore the Taboo nature that can arouse everywhere, I can't be more eager to discuss what would suit us best!
