*****
It was a Monday night, almost midnight. It was the first full week after my first year of college. I had taken a summer job at a generic big box retail store. It wasn't the best job, but it was easy enough work, and the money wasn't bad all things considered. I had worked until closing time, done all the restocking and swept the storerooms. Finally, I could clock out and leave. A quick trip through a drive thru for a value meal, and I was heading home. As I pulled up to the house, I noticed my sister's car parked in my normal spot out front. Well, Stacy was home finally.
My sister Stacy was 22, three years older than I, and had just finished her third year of college. Her classes finished up almost a month ago, but she spent some time with friends at the beach, and then was in Denver for two weeks babysitting for our Uncle Steve and Aunt Ellen while they went on an anniversary cruise.
I opened the front door and headed up the stairs. I passed Stacy's room. The door was closed and there was no light coming from under the door. I assumed she was asleep. I really didn't care to be honest. I just wanted a shower and some shut eye. I had the dreaded back-to-back shifts. Closing one night, opening the next morning. It wasn't ideal, but it meant some overtime and I liked money. I washed the funk off my body, then pulled on a t-shirt and some gym shorts. I headed downstairs to grab a bottle of water before I passed out. I hit the bottom of the stairs and turned into the living room. I took one step and stopped dead in my tracks.
Stacy was sitting on the couch, staring at the TV. She was wearing some bright green shorts and a loose white tank top. Normally, I wouldn't have noticed what she was wearing, but tonight, one of the straps of her shirt was off her shoulders and pulled down pretty far, which left her entire tit exposed, nipple and all. I stood there slack-jawed. I mean, I had seen a boob before. I had a couple of girlfriends during high school - I had even gone all the way with Linda Myers a few times over spring break while her mom was at work. But on those occasions, the boobs were seen in the context of a romantic situation, in back seat of a car or on someone's bed. I had never seen a tit just out in the open like that. It was unexpected to say the least. No to mention, it was my sister.
I don't know how long I stood there. It probably wasn't more than a few seconds, but it felt like an eternity. I was transfixed by my sister's breast. Round and full, with a hard nipple protruding from the pink areola. It looked firm and soft and had the slightest bit of droop to it. Stacy just sat there, oblivious to my presence. A loud noise from the TV snapped me out of my fog. I looked down and shuffled into the kitchen. I braced myself on the counter and took a deep breath. That was... unexpected to say the least.
I opened the fridge and grabbed my water. I stood there a moment, pondering what to do next as I took a drink. I opened and closed a cabinet door to make some noise. Hopefully, that would give her a chance to notice her state of undress. I counted to five, and then went back into the living room. Stacy was still in the same spot, but now her shirt was on correctly, her boob safely stored away. I could see her nipple poking the white cloth covering it.
"Good night sis," I said as I walked to the stairs.
"Night," she replied, never once moving her gaze from the TV.
I got to my room, stripped down and climbed in bed. I had to be at work in eight hours, but my mind raced as I tossed and turned. The image of Stacy's full round tit was burned into my consciousness. My sister had nice tits. Her hard nipple just begged to be sucked on and played with. I felt my dick stirring. I reached down and took a hold of him for a moment and was surprised to find that I was hard. Maybe not throbbing-ready-to-fuck hard, but hard enough. Seeing Stacy's breast exposed had done a number on me apparently.
I knew growing up that Stacy was pretty. It was kind of hard not to notice. She had the bright smile, sparkling blue eyes, and flowing blonde hair that seems to always attract attention. My friend Colby had an all-out crush on her and used to tease me about my sister and her "big boobies". It got annoying fast. During high school, she had what seemed like a never-ending string of boyfriends. She was popular, and it was obvious why. She was tall, voluptuous, and gorgeous.
Despite all that, I had never really seen her as a sexual being. She was just my sister. She teased me when I started shaving, she teased me when my voice changed. She wasn't anyone I could ever have a sexual thought about. Even on vacations at the beach, seeing her in the bikinis she and Mom fought about never made me bat an eye.
But tonight, for some reason, that had all changed. I had seen her breast and it was clearly affecting me. None of the girls I had dated had tits that big, and Linda's (the last live boobs I had seen) were so small they barely qualified as breasts. And that was a couple months ago.
Maybe that was it. I hadn't been out with anyone really in a long time, so naturally the first tits I saw were going to get me a little worked up. That had to be it. It was just biology, a natural reaction. My mind at ease, I could relax enough to fall asleep.
I overslept a bit and had to rush out of the house the next morning to get to work on time. A delivery truck arrived as I clocked in, so the rest of my day was spent unloading, sorting, checking shipping lists, and putting things away in the storerooms. Naturally, on a day like this, I ended up working several extra hours to complete the task at hand. At least the manager on duty was appreciative, and even bought me some brisket and sausage from the BBQ joint next door in lieu of an actual lunch break.
Job done, I headed for home. With a day off in front of me, I was looking forward to relaxing and doing absolutely nothing. I pulled up behind Stacy's car again and went in the front door. I paused for a moment, a flashback to the night before playing in front of my mind's eye. I wandered into the living room for a moment, but no one was there. Exhaling loudly, I paddled upstairs. Again, Stacy's door was closed as I passed it. I dropped my keys and wallet on my dresser and went for the bathroom. I definitely needed a shower. The bathroom door was open halfway, the lights were on, the mirror fogged over, and Stacy was standing there facing away from the door. Her bare ass was pointing right at me as she rubbed a towel over her head, drying her long blonde hair.
And what an ass it was. Full, round, and inviting. As she moved, her cheeks jiggled lightly, and I fought an urge to reach out and grab it. Again, I found myself frozen to the spot. I didn't want to move or make a sound. I was sure that if she knew I was there, she'd freak out on me, and nothing but trouble would ensue. I couldn't help but stare at the nice round ass in front of me. As her arms moved, I would get glimpses of her swaying breasts as well. Finally, she stopped. That caused me to slide back down the hall and into my room before I was noticed.
I closed my door and caught my breath. Wow. What an ass. I looked down and could see my dick pressing against my slacks. Stacy's body had gotten me hard. Again. Clearly, my lack of sex in recent months was messing with my head. I waited a few minutes and opened my door to see Stacy, now wrapped in a towel, walking down the hall into her room. I sighed heavily and went into the bathroom. I stripped down and stepped in the shower. The warm water felt really good on my tight shoulders and arms. As I relaxed, I thought again about Stacy, her hard nipple, the cleft of her ass bent over in front of me. I grabbed my cock and started to stroke right there in the shower. I imagined touching, licking, feeling that ass and tit, and in pretty short order, I was shooting cum on the shower wall.
