Hey everyone. My name is Parker. I'm a 19-year-old college sophomore. I live with my older sister, Ashley. She's 21 and a senior. Our parents decided it'd be best for us to share an apartment for my first and Ashley's last two years of college. It saves money, and she and I get along great anyway, so there was no reason not to. Our apartment is somewhat small. It's got a main living space, a kitchenette, two bedrooms, and one bathroom. The bathroom has two doors, each leading to either of our bedrooms. Sharing a bathroom with Ashley was surprisingly easy. We'd talked about it before I moved in and devised a morning schedule to follow so that we wouldn't be fighting for bathroom time. It worked perfectly, that is, up until around three months ago.
It was a Wednesday morning, and I woke up around 8:30. I had class at 9:00, so I was in a bit of a rush. I knew that Ashley would be at her 8am class and wouldn't be done for the day until a little bit after lunchtime, so I didn't even bother knocking when I walked into the bathroom. To my surprise, however, I was greeted with the sight of my sister standing at the sink brushing her teeth. She was wearing nothing but a white cut-off tank top and a bright yellow thong. Now, I had seen Ashley in more revealing bikinis before, but there's a time and place for that kind of attire. Seeing her in this state of undress in our own apartment caused something in my head to tick.
I guess now is as good a time as any to describe how my sister and I look. Ashley's about 5'5" with pale skin, brown hair, and green eyes. I know from doing our laundry that she wears a 36C bra, and her body is in great shape from doing multiple sports in high school and club soccer in college. My friends used to call her "Assley," joking about how nice her ass was (or, I guess, is), and while I never verbally agreed with them, I certainly didn't disagree, so catching a view of her in that thong was enjoyable, to say the least. I'm 6'2", with pale-ish skin (slightly darker than Ashley's), light brown/dirty blonde hair, and blue eyes. I'm in decent enough shape, though my body is not quite as toned as Ashley's.
"Oh! Uh, good morning Ash," I said in a confused tone, "Why aren't you at your 8am?"
Ashley jumped slightly at my unexpected intrusion, then turned to face me, toothbrush still in her mouth. "Morning, Parker!" she replied, "Yeah, I forgot to tell you, I dropped that class. I totally bombed the first test, and since it was just an elective I don't need for graduation, I just decided to drop it. Sorry I didn't mention it."
While she was rinsing out her mouth, I responded, "Well, I've still got class at nine, and if I'm not mistaken, so do you. Puts a bit of a wrench in our morning system, doesn't it?"
"Yeah, I'm sorry, I guess I didn't think that far ahead," she said, "But I really need to shower. Can I take one now, and then you can get in while I do my makeup?" I was initially surprised at her suggestion. In the year-and-a-half we'd been living together, not once had either of us used the bathroom while the other was taking a shower - we always waited. Why was she suddenly so comfortable with all of this? Well, I certainly wasn't going to argue with it, I was happy enough getting to look at my sister in her underwear.
"Okay, that's fine with me, just make it quick okay? I think we're both in a rush, here," I said.
"Great," Ashley replied. Then, she moved her hands to the hem of her tank top and started lifting it up, right in front of me. When about half of her under-boob was exposed, she paused, looked at me and said "Well, turn away so I can get in the shower, doofus." I was momentarily stunned by the view of her incredibly tight tummy, and I'm a complete sucker for under-boob. But my sister's? I knew I shouldn't be getting turned on by it, but the growing tent in my boxers said otherwise.
"Right, sorry, let me know when you're done so I can hop in," I said as I reluctantly turned away and walked back into my room. I left the door to my bedroom slightly ajar and sat at my desk, which gave me a slight view of the shower, with its opaque glass walls and door. The bathroom is laid out such that the shower is right next to the door leading to my room, the sink is right next to the door leading to Ashley's room, and the toilet is in the middle. That also meant, however, that Ashley could see me at my desk if she decided to look out from the shower at a particular angle. I waited until I heard the water running and the shower door close, then scooted my desk chair over slightly for a better look. Even the mere sight of my sister's naked silhouette through opaque glass caused my heart to race and my erection to grow. I began to lightly stroke myself over my boxers at the thought of the situation. When I was just getting into it, though, I heard the water turn off. As quick as I could, I moved my chair back to my desk, out of sight of the shower. I heard the shower door open and close, and then Ashley's head peeked through my doorway.
"Shower's all yours," she said. I looked up at her and saw that she was, in fact, still naked. About a third of her torso below her head was visible in the door, and she was using one of her arms to cover her boobs while she used the other to prop herself on the door frame.
"Okay, thanks Ash," I replied as nonchalantly as I could. I stood up, sporting a pretty obvious tent in my boxers. I think I saw her take a quick glance down at it before she retreated to the bathroom. When I walked in, she had wrapped herself up in a towel and was at the mirror, doing her makeup and hair. I reached into the shower and turned the water back on. It didn't take long for it to get back up to temperature. "Ahem," I said, "A little privacy?"
"Oh, don't be such a prude," Ashley replied, "I'm not looking, and as long as you don't take ages getting in and out of the shower, I won't see anything. Besides, it's not like I haven't seen it when we were kids."
Okay,
I thought,
so that's how she wants to play this.
With that, I dropped my boxers to the floor, stood there for a beat, and stepped into the shower. I'm almost certain I saw Ashley peek at my exposed penis out of the corner of her eye. That was about as interesting it got that day though, as Ashley was already gone when I got out of the shower.
I wonder if there's a way I can push this further,
I thought to myself.
I woke up the next morning at around seven. I didn't have morning classes on Tuesdays or Thursdays, so usually I liked to take the mornings slow, waking up around ten. Not today, though. Remembering the events of yesterday, I walked into the bathroom, hoping I'd get to see Ashley again. To my delight (and surprise), Ashley was standing at the sink again, this time wearing only a white lacy thong. I had a direct view of her bare side-boob, and I could see her slightly stiff pink nipples surrounded by quarter-sized areolas in the mirror. I leaned against my door frame and cleared my throat.
"Oh, shit, uh, good morning," Ashley said as she moved one of her arms to cover her boobs. "You're up early today!"
"Yeah, I figured I'd try getting an early start today," I said, "Try to make use of the morning since I don't have class till 2:30." I should mention that there was a good-sized tent in my boxers yet again, half from morning wood, half from the sight of my sister in nothing but a thong. "So, I'm guessing you sleep that way, then?"
Ashley seemed perplexed at my question at first, then a look of realization came over her face. "Oh, topless? Yeah, usually. I just throw on a tank top in the morning if I know I'm going to see you. Otherwise, I go tits out." She said that last bit playfully with a goofy smirk on her face.
"Oh, okay," I said. "Well, I'll leave you to it, then. Let me know when you're done with your shower."
"Sure thing," she replied. I walked out of the bathroom and sat at my desk. I left my bathroom door a little over halfway open, so that if I leaned back in my chair, I could see Ashley at the sink. She had lowered her arm again, and I could see her bare breasts from the side. I was already rock hard, so I pulled my boxers down and started stroking my cock as I watched my sister at the sink. Ashley finished at the sink, and started to turn towards the shower. I leaned back forward just in time to hide back behind the door without her noticing. I heard her turn the shower on and step inside, and leaned back in my chair again to watch her through the shower door. As I stroked, several drops of precum came from the tip of my cock, providing better lubrication. I was pretty steadily stroking myself when Ashley stopped the water and stepped out of the shower. Luckily, I had leaned forward again to avoid being caught watching her. What I didn't anticipate, however, was Ashley going immediately from the shower to peeking her head around my door. She got an eyeful of me sitting in my chair, boxers around my ankles, hard cock in hand, stroking away.
"Oh! Um, shower's all yours," she said. But she didn't immediately avert her eyes from the impromptu show I was giving her. She lingered in the doorway for a bit while I feigned trying to cover myself up.
"Jeez Ashley," I said in about as good of an annoyed voice as I could muster, "Maybe knock next time?"
"I'm sorry," she said as she ducked back into the bathroom. I pulled my boxers up and followed her in immediately, getting a good view of her ass before she wrapped herself up in a towel. I stood near the shower as I waited for the water to get back up to temp, which again didn't take long. Without saying anything, I pulled my boxers down and stepped into the shower. Through the glass of the shower, I could see Ashley take her towel off and return to the sink counter, then start putting her makeup on. I jerked off in the shower, using Ashley as inspiration. When I came, I let out a couple of low grunts as my cum sprayed against the shower wall. I saw Ashley turn slightly in my direction. She had to have seen me jerking off. By the time I was out, Ashley was gone again.
Well now she's seen my hard cock, and I've seen some TnA. Things are progressing nicely,
I thought to myself.
The next morning, I woke up with a hardon already. Classic morning wood. I walked into the bathroom and saw Ashley at the sink wearing a black cropped tank and a neon pink thong. "Morning Ash," I said as I walked up next to her.
"Morning," she said after she spat out her toothpaste.
"Decided to cover yourself up today? Glad some modesty found its way back into you," I joked as I tugged at her tank top.
"Oh ha-ha," she said mockingly. "Well, unlike yesterday, I actually knew you'd be in here this morning, so I put something on. Took me an extra minute or two to actually find it in the bottom of my hamper, though."
"Oh, poor you," I replied, "Your precious two minutes." Then I got an idea. "Well, I if it really is too much of hassle for you to put on a shirt just to get ready in the morning, you could just not worry about that. If you want to just go topless like you were yesterday, feel free. I don't mind if you don't mind." I couldn't believe the words coming out of my mouth, but I wasn't exactly thinking with the head on my shoulders.
"Well," Ashley said, "I guess it wouldn't be anything you haven't already seen anyway. That, and it would save me some time. It adds up, you know. I'll consider it."
"Yeah, no pressure or anything," I said, "I just want you to be comfortable in the mornings is all." I stepped away and reached for the shower door, "Do you mind if I take a quick shower?"
