While watching my sister shower… [Mf, inc, voy, reluc, oral]

This is part 2 in my dark minds, dark places series. This can be read independently or in conjunction with part 1 – When I Came Home From College (see posting history)

For several weeks I had been watching my sister Katie shower in the bathroom without her realizing it. I got off on it in a way that nothing else had ever turned me on. I was 25 and with her being six years my junior it made it all the more hot. It usually started once I heard the door lock. I immediately would rush downstairs into the basement, climb up the footstool, push out the floorboard in the bathroom closet, and climb silently through. Once inside I watched her through the slats of the closet door as she showered with my dick solid in my hand stroking silently to her hygiene ritual.

Throughout this process with each passing voyeuristic endeavor I became more bold. I would often try to predict when she would enter so I could watch her undress and I wouldn't worry about being absolutely silent if it meant enjoying a little more of her or enjoying myself a little more. I thought I easily had it covered and there was no way I was going to get caught. I even took to raiding her room when she wasn't home to check out her underwear. That's when I noticed a little box in her underwear drawer. Inside I was shocked to see a little menagerie of drugs – marijuana, molly, pain pills. So my little sister had some secrets of her own after all….

So continued my secret retreats into the bathroom closet during her usual shower times. Once I accidentally bumped into a shelf in the closet while jerking off. I froze and so did she on the other side of the frosted glass. And for a moment we both waited. Katie stood with the water running over her and I watched her from inside, cock in hand, through the slats. After what seemed like forever Katie continued with her ritual as if nothing had happened, and so I continued with mine – stroking away with a bit more awareness of my surroundings. Finally my favorite part came up – where she exited the shower dripping wet. I squeezed my cock harder and started preparing myself to cum my eyes instinctively closing from the pleasure.

Yet just at that moment, most likely remembering the noise that came from the closet earlier, she reached over and opened the door. Suddenly she gasped and my eyes popped open in surprise. There I was standing before her with my pants around my ankles, my dick in my hand.

“Matthew!” she could barely let my name escape her lips. Her cheeks flushed as her eyes traveled down my body in complete shock still completely naked. “I'm going to tell mom and dad!” She said grabbing a towel and began to turn toward the door of the bathroom. I had to think quick. If she told my parents I would be out on the streets with too much debt to afford a place to live. I needed her to stay quiet.

“Hey wait a minute Katie!” I ordered suddenly reaching my arm out and grabbing her by the wrist before she could get away. Her eyes immediately returned to me, looking down where I gripped her and then at my swollen cock again. “You can't tell mom and dad!”

“Why not?” She asked with a tone of self-righteousness in her voice, “You were invading my privacy!”

“Because…” I said searching my mind for the appropriate response, “because you're not so innocent yourself,” I say suddenly formulating my game plan.

“Oh yea right, and why's that?” she asked still holding her towel over her breasts.

“I know about your little box of drugs in your panty drawer and I will show them it if you breathe a word about this,” I said suddenly taking control. Katie's eyes opened wide again realizing that I had trumped her unsure of what to say next. “Besides,” I continue, “I wasn't doing anything to harm you. Look at me,” I say drawing her arm closer to my still swollen cock, “if anything this is a compliment to your beauty,” and as I say the words I step closer to her so she can feel it directly with her hand. For a moment she feels it and my cock twitches at the touch, and then she pulls away.

“You're not going to tell mom and dad about the box if I stay quiet about this, right?” She asked making sure our agreement was solid.

“Absolutely not, I have no interest in getting you in trouble. I just need to be here because I have too much debt right now to be kicked out of the house. You have to understand I've been home two months and I haven't gotten laid even once. I'm going crazy here and then your beautiful ass is marching around the house half naked all the time. This is the only pleasure I get at all. Don't take it away from me,” I say as I slowly pull at her towel making it fall to the floor. She doesn't resist as I slowly begin to stroke again looking at her. I was used to convincing skittish teenage girls in college to let out their wilder side. I knew exactly the line to ride before going too far.

I suppose this is an important time to explain how I look. Being Katie's sister I also was blessed with some good genes for my physical appearance. I have dark hair, I'm tall, and am in very good physical shape. My stomach is defined enough to pinch inward near the bottom with a happy trail that leads down to my above average cock in both length and girth. Since I was a teenager I made it a point to keep my balls and cock shaved while I trimmed the hair around it.

While I stood there stroking myself taking her in the look in my face becomes dark and primal and I can sense her becoming flushed. I knew I was turning her on even though I could see it in her eyes that she was fighting against it. But she was entranced, watching me stroke at her, seeing me take charge over the situation. Still holding her by the wrist I bring her hand in close again, but this time she did not resist. I slowed my strokes so that she could feel how warm and soft my solid cock was. As I held my cock by the base she took the head in her small hand letting out a low slow moan.

I let go of her wrist and her hand remains feeling the head of my cock delicately as if she was still trying to decide on whether what she was doing was right. I take my hand and wrap it around her back pulling her closer to me and beginning to increase my strokes. This seems to have awoken her from her trance as she begins to pull away mumbling about how this isn't right. But I hold her tight by the hip, refusing to let her go, whispering for her to wait. She stops struggling and allows her naked body to sink in close next to mine.

Then she lets her hand slip against my inner thigh and lightly she begins to stroke it, my balls bouncing against her hand. That's when I turn my face inward to her body and press my face against her tits. Almost in a motherly fashion she pushes them back into my face so I open my mouth and begin to suckle on the tits that I've stared at through the slats for all this time. They were so big I couldn't fill my mouth with them and they poured out of the side. As I suck and bite on her tits I hear her breathing become more shallow, gasping as I pinch her nipples between my teeth.

Finally I can't take it anymore – sensing her arousal I push down on her head and she begins to kneel. I run my smooth cock against the side of her cheek and push it against her lips. For a moment she hesitates, glancing briefly to the locked bathroom door, but then she opens her mouth and lets me push myself in. She started sucking thirstily. For all her hesitation she was all in now. And she knew how to suck cock. I could tell I wasn't her first. I look down and admire the situation of my little sister taking my cock in her mouth like a thirsty little slut.

It doesn't take long with her talents, going deep and using a lot of tongue work, to finally bring me to the point of being ready to orgasm. As I tense up I moan and lean back. Katie increases her head bobbing now hungry for my cum and finally I give it to her.

What happens next neither of us expected. Thick ropes of cum start filling her mouth and surprised at how much she begins to back off, her mouth already full. With cum dripping down her chin and onto her tits we both realize that I'm not finished and another rope coats her freshly showered face and another getting into her hair. Dripping with cum I continue to unload so turned on by what is happening. Her face is coated but even as the last drop dribbles down onto her lips she looks up at me and smiles, cum still in her mouth. She swallows and begins to lick herself clean finally having to use a towel to clean up the rest.

Slowly Katie stands up looking slightly more confident and is looking me directly in the eye. Then she does something unexpected and kisses me right on the mouth holding it there making me taste my salty aftertaste. Then suddenly she pulls away wrapping the cum towel around her and says, “It's better than using my panties, isn't it?” Then she walks out the door. It was only then did I realize that my little sister wasn't as innocent as she appeared to be.
