Growing up in a family of four, it was just my sister and I. I was the older brother by a year and a half. We were typical siblings. We could get along great one moment and be at each other’s throats the next. We experienced a pretty normal childhood.

My mother and father are both tall. My father is 6’4” and my mother is 5’9”. So it was a matter of time before my sister and I grew to be tall as well. I was a late bloomer not getting most of my
height until high school. Since she was just a little younger than I, we both hit puberty around the same time. It was weird watching my sister grow into a young woman.

My sister went through most of the typical stages for girls. In junior high, she was as flat-chested as they come.  Then long about her freshman year in high school, she really started to blossom. She went through the awkward stage in stage where her body was growing so fast that parts were not growing in appropriation to each other. She was shooting upward at record speeds while
also filling out in the hips and chest. She went through that clumsy stage in early high school.

My sister was always an above average athlete. So I watched her play softball, basketball and run competitively. My mother was well-endowed with big, beautiful breasts. And it became clear by my
sister’s sophomore year that my sister was going to be blessed with those same attributes. As her bust expanded, it became more difficult for her to compete on a high level in most sports. That’s when my sister started to focus more on her interest in music.

It was about that time that I start to feel a vague attraction for my sister. I couldn’t put my finger on it at first but I found myself looking at my sister in new ways. My sister was becoming more
and more of an attractive young woman.  Growing up we were pretty close and comfortable with each other from a physical standpoint. It wasn’t a big deal to see my sister in a tight swimsuit or even the occasional glimpse of her in a bra. But now I wanted to see more of my sister. I found myself attracted to her and wondered if she thought about the same as me. So I began to push the boundaries a little.

It wasn’t uncommon for my parents to leave my sister and I alone at our house once we reached the age of 13-14. So we could be at home along for long stretches of time. Both being physically active and involved with a range of sports and activities at school, we would be showering at odd times of the day. That’s when I decided to see how my sister would react to various stages of undress around the house. I would start to walk around the house with no shirt on or just briefs.
But I didn’t seem to generate my interest in my sister.

Then late one day an opportunity presented itself. We were home alone and I was finishing showering. I exited the bathroom with only a towel wrapped around my mid-section. She was seated in the family room watching TV. I walked into the family room with my towel wrapped around me making small talk.  It seemed like she was trying to not look at me. So I sat the big arm-chair kitty corner from her. I sat on the edge of the chair and leaned way back into the seat. With my long legs the bottom edge of the towel didn’t come close to reaching my knee. Thus I knew my sister had a perfect angle to look straight up my towel at my dick and balls.

I sat like that for several minutes pretending to look out the window, but keeping an eye on her eyes. Then you could tell that she saw my prize. She looked away quickly pretending not to notice. But within a few moments, her eyes returned to my exposed crotch.  She started for a several moments before looking away. I shifted in the chair causing my towel to move and expose more of my nakedness to my sister. At that point she became uncomfortable and exited the room.

She hadn’t made any outward signs but I knew that she had noticed me and her eyes lingered. Now I needed a plan to see how truly interested she was in me. About two weeks later I tried another variation of the same incident. I exited the bathroom with only a towel around my waist. My sister was in the kitchen and I pretended to fix myself a snack.  I had loosely tucked the towel into my side so I could use both hands. With a little flexing, the towel dropped from my waist just as I was turning away from the island with my hands full. Of course, I pretended to be embarrassed and set the items down as quickly as possible so I could replace the towel to
my waist. But my manhood was clearly exposed and I knew my sister had a good clear view.

She brushed it off as an accident and joked around about how I should be more careful.

My sister and I usually didn’t share a bathroom with our bedrooms being on different levels of the house. But I decided I needed to find a way to share her bathroom. One afternoon as she was
showering after practice, I knocked on her bathroom door and asked if I could borrow the dental floss. She gave me permission to enter since the shower curtain was not see-through. I entered and proceeded to floss my teeth in her mirror, making sure to take my time.  Finally she shut the water off.  My heart fluttered to see if she would open the shower curtain exposing herself to me. But she reached for a towel instead and dried off behind the curtain.  When she did step out of the shower stall she had a large towel wrapped around her mid-section. Her large C breasts were spilling out from above the towel.  I had a great view of her long toned legs. The bottom of the towel was just long enough to hide her sex. She caught me stealing a long stare at her body. I thought she might scold me for intruding but she smiled and proceeded to enter her bedroom
to get dressed. I took that as an encouraging sign.

While I was contemplating my next move, something unexpected happened. I was showering one afternoon after practice when she knocked saying she needed something. I gave her permission to enter knowing that she would have full view of my body since my shower curtain was see-through. She tried to busy herself at the sink trying not to look. I pretended to continue with my shower as normal.  I washed my hair all the while watching her. Finally she took a long stare at my crotch. I finished quickly and turned off the shower, opening the curtain. She didn’t flinch and proceeded to tinker with her make-up. But I knew the mirror offered her a full view. As I stepped out of the stall I said, “If you are going to see me naked then it’s only fair that I get to see
you naked in return.” She blushed but didn’t say anything. I decided not to press the matter at that moment.

A few days later, after we got home from practice, she announced that she needed to use my shower instead of hers for some lame reason. I saw it as an invitation to view her nakedness. After she was good and warm, I entered the bathroom and told her I was going to shower after her. I was privileged to see her firm breasts and trimmed bush. It was truly a sight to behold, something I had been waiting for for a long time. She applied conditioner to her long hair and gave me a great view of her ass as she bent over. Naturally, my member began to stiffen.

As she finished and exited the shower, she made no attempts to hide her privates.  I was standing only in my running shorts, which by now had large tent in them. She looked at me and commented, “Wow, it looks like someone has enjoyed the view”  I grabbed the waistband of my shorts and pulled them off. She was standing there naked looking at my firm dick. She didn’t say anything or move. She just starred. I didn’t attempt to move or hide. I just let her enjoy my manhood as I enjoyed every inch of her body. Slowly she reached out and put two fingers around the shaft. I couldn’t have been harder. She was mesmerized. She moved closer and wrapped her whole hand around my stick. She began to push up and down with her hand. The sensations
of her warm, soft hand felt wonderful.

I reached out and caressed the side of her breast. She shivered but made no attempt to push my hand away. I cupped the full weight of her breast in one hand. I tweaked the nipple and she smiled. She lowered herself to the floor so that she could get a better view of my penis. She slowly jacked me off while she examined my balls. She slowly ran her fingernails along the underside of my sack which gave me the chills. She leaned forward and ran her tongue from the base to the tip.
She paused at the tip swirling her tongue around the head. She opened her mouth and sucked on my head. She didn’t try to take my whole member instead focusing on just the tip and head. I wanted more but wasn’t going to force the issue. After a few minutes of simultaneously jacking me with one hand and kissing the tip, she stood up and said, “we may have to do something about your excitement in the future.” Before I reach out and touch her again, she walked out of the bathroom leaving me with a raging hard on.

I figured that my time would come soon enough. So I took a hot shower and finished the job that she left. When I finally came, it was with fresh images of her beautiful body in mind.
