"Shit!" I thought to myself.
My sister knew I had come home and was watching her, but how?
I didn't make any noise I thought she could hear when I got home, and I crept out after like a freaking Ninja, so that couldn't be it. I didn't drive home, so there was no car door slamming. The blinds, maybe? I had shut them when I had left earlier to play basketball. When I got home, I heard the splash in the pool. I opened them to look out. I replayed the sequence of events again. She did look across the back of the house. That had to be it.
"The fucking blinds. Oh.... the fucking blinds!" I mumbled as my heart sank. The blinds I had shot a load onto and never had the time to clean up. I hoped she hadn't gone into my room. I pumped an obscene amount of cum into those blinds, and it would probably be hard to miss, especially if she knew where she was looking.
Growing up, we had been taught to clean up after ourselves. Looking back, what a helpful lesson that is now.
"Well, can't go back in time now," I assured myself, not that I wanted to. What's done is done.
Somehow, I didn't feel bad at all about the whole thing. Sure, initially, I was more worried about what Kate was thinking about me, what she might say, and to whom. But, on the other side of the coin, I'd had an awesomely intense orgasm while watching my smoking-hot older sister play with herself. It was a good afternoon, I reasoned, for me anyway, so far. I don't know how it could have been any better!
There was no sense in delaying the inevitable. I turned around and headed back home. I repeatedly played out my return home, what I would say, and how Kate would react. I tried to think of a scenario that didn't end in a lecture, a slap, or something that would ruin my sparkling mood. She was in the backyard. It was her fault for being out in the open without reasonable expectation of privacy. That's what Judge Judy would say, I was sure. I felt confident she wouldn't see it that way, but what was I supposed to do, not look? I'm only human; that was the hottest thing I'd ever seen.
I reached the front door, grasped the knob, and turned it. I stepped into the entryway and peered into the living room. It was empty. I didn't hear any noise. No music or television was on downstairs. Kate's car was out front, so it wasn't like she had left. I quietly climbed the stairs to the second floor and headed toward my room. I pushed the door open and slipped inside.
I walked over to look at the blinds. Cum had dripped from the blinds down to the hardwood floor and formed a little sticky white pool twice the size of a quarter. I reached over to the gray box of Kleenex on my desk and pulled out several sheets to wipe up the mess. Maybe she hadn't seen this? But somehow, she knew. My money was still on the opening of the blinds, I decided.
Just then, the bathroom door swung open. Standing in the doorway was Kate, wearing a thin white bathrobe tied with a black sash at the waist and ended just above her knees. Her hair was still dry and tied back with a hair tie, so she hadn't taken a shower yet. I noticed her nipples poking into the robe's fabric slightly, just enough to announce their presence and, more importantly, the lack of a bra.
"What's up, little brother?" Kate asked knowingly.
"Hi, Kate," I replied. "I guess I have some explaining to do," I said, glancing down at the ground to avoid making eye contact.
"I'd say THAT is explaining for you, wouldn't you?" she implied, pointing to the puddle of cum on the floor below the blinds. She looked up at me as if waiting to see my reaction.
"I'm sorry," I lied, peeking up at her to get a read on her mood. But, of course, I wasn't sorry, not at all, but she didn't know that.
"Sorry for what?" she replied straight-faced, her expression slowly turning to a smile.
She didn't seem mad at all. I hoped I was reading the situation correctly, but it seemed I had dodged a bullet.
"I shouldn't have been spying on you," I replied, milking the sorrowful angle. "We went to play basketball, and it was just so hot we called it and came home early." I did my best to keep an apologetic tone to my words, even if there wasn't an ounce of regret inside me.
"I can see that you........came...... home, or maybe more like came at home!" she noted with a grin.
"You aren't mad?" I replied, a little confused but feeling more confident I had escaped the wrath I had felt sure to come only minutes before.
"Nah. Truth be told, I shouldn't have been out by the pool doing what I was doing anyway," she explained, motioning towards the window.
"When you left, I figured you would be gone awhile, and a little dip in the pool would feel so refreshing," she continued, gazing again upon me.
"I should have told you I was back," I replied. "I heard a splash in the pool, looked out, and.........," I trailed off, unsure of how I would finish the sentence.
"And......... what?" Kate inquired.
"Um....," was all I got out as I looked for the right words.
"Um?" she remarked, pausing for a second. "What did you see?"
"You were swimming and didn't have any clothes on," I began. "And then you got out of the pool......." trailed off again.
"And you watched me fuck myself, right?" answering the question herself before I had time to think how I would complete my sentence.
"Um...yeah," I replied.
Then, my sister looked me up and down, which made me a tad nervous and then smirked.
"Steve, I'm not mad or anything. Everyone does it," she said, shrugging her shoulders. "It's no big deal."
Kate was selling herself short. It was a big deal. It might have been the best moment of my sexual life, but I wasn't about to let her in on that just yet.
"Well, I don't think everyone does it while their brother is watching, do they?" I speculated.
"Well, I am a woman, and you are a man," explaining the obvious. "It excited you," pointing up and down at the blinds and the cum on the floor again.
"But you're my sister, so we probably shouldn't be talking about this anymore, should we? I won't say anything to anyone." I assured her.
