My Sister Sally pt 1

Happy new year Patreons. 2019 begins with a new story, which should be coming out hot and fast in multiple parts this month. 

It started with gymnastics. My sister Sally from a young age had participated in gymnastics and built a muscular physique from all that training. She used to enjoy showing me how strong she was all the time, bragging about how many pull ups she could do and teasing me that I couldn’t do any, or challenging me to arm wrestling contests that she would almost always win. With me being her older brother by one year, this was embarrassing.

By the time she had entered her freshman year of high school, she had realized that she cared more about building a muscular physique than about the gymnastics, so she quit and dedicated herself to the gym. She put pictures of female bodybuilders up in her room and set goals for herself. Pretty soon, she was starting to look like the women in those pictures.

I didn’t know it until then, but I really had a fetish for those bodybuilders. And my little sister starting to look just like one? That was confusing. One day I caught her coming out of the bathroom in just a towel. Her biceps popped from her arms without even trying, encrusted with a blue vein across the top. I also noticed protruding trap muscles and the definition in her shoulders. My mouth must have dropped, because Sally just smiled a mischievous smile.

“Not bad for a girl, huh?” she said. Then she flexed up one arm. Her bicep looked huge and hard! And her triceps popped. I could feel my dick starting to get hard, and that made me really uncomfortable, and I blushed.

Sally laughed. “I didn’t know you had a thing for muscular girls!” she said, picking up almost instantly on my arousal. 

“I don’t know what you’re talking about!” I retorted awkwardly and tried to shove my way past her into the bathroom to hide behind a locked door.

When I tried to push her aside, it was a lot harder than I expected. She hardly moved. Her smile broadened.

“Oh sure…” she said with a smirk. Then she moved out of my way and casually let the towel drop. “Ooops…” she said, bending slowly to pick it up.

My eyes widened as I took in the sight of her rippling six pack abs, defined obliques, and what looked almost like pectoral muscles behind her small breasts. She slowly gathered her towel then sauntered back to her room, totally naked. I watched the defined muscles in her back and the definition in her thick ass until she stopped in front of her door, turned, and winked at me. 

“Have fun in there,” she quipped before disappearing into her room. My dick was harder than it had ever been in my life. I rushed into the bathroom, locked the door, and stroked myself with mad energy. I ejaculated so quickly and without thinking, leaving a big mess to clean up.
