Author's note: Though not absolutely necessary, the reader may first want to review the prequels "Quarantined... With My Sister" (which is part 1) and "My Sister's Birthday" (which is part 2) in order to obtain a deeper introduction to the storyline and characters as presented in this independent sequel. Whereas those 2 stories were recorded from the brother's perspective, this one steps into the mind of the sister. This narrative goes out to all those who didn't like the cliffhanger ending of "My Sister's Birthday.". ;) Enjoy!!
P.S. "Thank you" to @Gabbygee for the motivational input & authentic female perspective!

Fuck.
That was all I could think as I watched my brother and his wife walk out the front door with my husband for him to return them to the airport.
My amazing brother had secretly fucked me so wonderfully over the past couple days, but now I felt like I had fucked myself... in a bad way. And him too.
It was never supposed to end up like this. Why couldn't she have just kept her mouth shut?? And why did I have to go and make it worse??
As the door slammed behind them, leaving me alone to imagine how horribly awkward their car ride would be, I collapsed on the nearest chair and let my mind wander back to the beginning.
All
the way back... 15 years prior, to when I had just turned 18.
+++++++
My brother was 21 at the time. We had always enjoyed a close sibling relationship throughout our growing up years, in part because of our playful personalities. On one of the first mornings that he was home on a weeklong break from college, that same sense of childish spontaneity prompted me to hide in his bedroom closet while he was taking a shower -- so that I could scare the crap out of him when he walked back in.
I buried myself between the shirts hanging on the rack, and pulled on the bifold doors until they were almost completely shut -- leaving just enough of a gap so that I could see whenever he walked in. I considered jumping out of the closet the instant he walked through the door, but I guessed that he'd be even more scared if I waited a bit and let him think he was alone... so, when I heard the water turn off, I took a deep breath and prepared to be still for as long as possible.
A few minutes later, I heard the door open. Through the tiny crack in the closet doors, I saw him walk in with his back toward me. Shirtless, with only his towel wrapped around him, I couldn't help but notice that his shoulders seemed to have broadened since the last time I saw him. Although my brother's physique was nothing remarkable, I had always thought he was handsome -- and often found myself dating guys that looked similar to him.
When he turned around, I almost gasped aloud. The front of his towel was -- umm --
protruding
.
And yet, that unexpected discovery -- one that almost caused me to betray my hiding spot -- was not the end of my predicament. It was merely the start, because -- in the next moment -- my brother dropped his towel.
I had to quickly clasp my hand over my mouth to keep myself from making a noise.
Fully engorged, his virile 21-year-old cock sprang to life, sending a strong pulse of erotic energy through the room. I had been with a few different guys, so it certainly wasn't my first time seeing a penis...
but this was my brother's
.
As the initial wave of shock at what I was seeing washed over me, a second -- perhaps even more startling -- realization occurred:
I liked it.
I
liked
staring at my brother's thick cock... and his heavy-looking balls... and his manicured trail of pubic hair... and his very desirable nakedness.
The truth is, I had actually fantasized about my brother on and off over the years: sometimes he spontaneously showed up in my dreams, and at other times I purposefully daydreamed about him. Many of those times led into my hand disappearing between my legs and successfully pleasuring myself. And yet, he was my brother, and so I forced myself to dismiss those forbidden lustful thoughts as inappropriate, childish, wrong, and "just a stage."
But on that fateful day that I found myself staring in awe at his very aroused junk, I swiftly concluded that my fantasies had never been "just a stage." No, they were deeply genuine... they were permanent... and the implication was stunning: I
wanted
my brother. I wanted to...
dare I say it??
... be
intimate
with my brother. It was all I could do to not rush out of the closet and jump his bones.
In the midst of those crazy thoughts, though, what happened next in my brother's bedroom blew my mind even further. Obviously without knowing that he was inadvertently putting on a show for a very taboo audience, my brother calmly laid down on his bed and propped some pillows behind his head. My viewpoint was from his side as he sat back, pulled his knees up toward his torso... and wrapped his hand around his towering cock.
Holy fuck.
My heart was racing a mile a minute.
Am I about to watch my brother jerk himself off?!?
The answer was obvious. Transfixed, I stared at the scene... drunk on an overwhelming cocktail of feelings that included shock, lust, guilt, satisfaction, fear... and a desire to reciprocate.
I pushed my hand inside my loose-fitting pajama pants. I liked to go without underwear at times -- and since that particular morning happened to be one of those times, what my fingers swiftly contacted was my bare pussy... my
soaking wet
pussy. I strained to hold back the moan of pleasure that desperately wanted to escape my lips.
My brother, meanwhile, soon began to make some sounds of his own. Passionate sounds. Sexual sounds. Sounds a sister should probably not hear a brother make -- especially if that sister is turned on by hearing her brother make those sounds. His wrist was jerking rapidly now, and the motion made his loose balls vibrate alluringly as he stroked the length of his impressive rod.
Two of my fingers had found their way inside of me, and my thumb was rubbing my clit with the same pace that my brother was using to pleasure himself.
He raised his ass up off the bed. He was really pumping himself furiously now.
I fingered myself even more fervently. If he was going to cum, I wanted to do the same.
"Oh fuck... ohhhh fuck... oh fuck," my brother started whimpering. I wanted so badly to echo him... to express my sexual pleasure too... to open the closet door and lick the perfectly-shaped mushroom head of his beautiful cock...
But before I could even consider the risk/reward of doing any of that, he came.
And -- as I watched thick white strands of cum fly out of his cock and paint a pattern all over his torso -- I came too.
The euphoric wave of climax sent breathtaking chills throughout my entire body. I closed my eyes and willed my heart rate to slow down, feeling as if I might pass out... but knowing that I dare not make a sound.
I was no stranger to masturbation, but that one felt different. Completely different. As I stood there silently in the closet and watched my brother clean himself up, the reality of what had just transpired slowly set in:
I just mutually masturbated with my brother -- without him knowing about it.
Still naked -- a bold move, since he would've known that his sister and parents were somewhere in the house -- my brother eventually got up and darted across the hallway back into the bathroom. As soon as I heard that door shut, I seized the opportunity to flee his room as quickly and as quietly as possible.
+++++++
I never dared confess the events of that day to my brother, but that day forever changed the way that I looked at him... and it increased how often I willingly let my mind wander into fantasy after fantasy about things that I'd like to do with him. Those lustful fantasies were always marked by a twinge of sadness, though, given the seeming impossibility of ever being able to act upon any of those taboo thoughts.
Unfortunately, the forbiddenness of our relationship wasn't the only obstacle to my secret longings: a few weeks after his private performance, he proposed to his college girlfriend, and they ended up getting married only a few months later. As if incest wasn't bad enough, now my brother would have to commit adultery if he were to ever be with me. I resigned myself to the disappointing likelihood that nothing would ever happen between me and him.
I threw myself into relationship after relationship trying to find a guy that could appreciate me, respect me, delight me -- and sexually excite me -- as much as my brother. I never did, but about 9 years later, I decided to say "yes" to a handsome man who had financial success, a solid career, and wasn't a complete loser in bed. No one would ever compare to my brother, but I surmised that I could love my fiancé enough to make it work -- and it was better than being a serial dater for the rest of my life.
Oddly enough, as our wedding drew closer, I gradually discovered that I wasn't the only one who thought my fiancé was attractive. I didn't notice it right away, but over the course of several interactions, it became apparent that there was another woman who
really
seemed to enjoy her time with him: my sister-in-law.
My brother's wife
.
At first, I was disturbed, annoyed, and even a bit resentful -- not just for my own sake, but also for my innocently unaware brother. However, about a week before the wedding, a joke made by one of my bridesmaids about my fiancé's bachelor party unintentionally gave me a terribly wicked idea and completely flipped my perspective.
