When I was seventeen I worked part-time at a store. It was great, after school I could make a few bucks of my own and I got to meet a lot of high school girls that worked there part-time too.
Sarah came to work for the store and it did not take me long to strike up a friendship with her. She was 16 and was thrilled to get her first real job. She had been doing babysitting for a couple of years to earn money and still did it when she could.
One evening, she told me about babysitting her eight-year-old nephew the weekend before, and how she had showered with him before she put him to bed. The vision of this 16 year-old well developed girl showering with a young boy flustered me and I said, you did what? Sarah giggled and said 'he's only eight, silly.'
Over the next couple of weeks our friendship developed. I finally got up the nerve to ask her out on a date. She said that she could not go because she had to babysit, but that I could come over to her brother's house and hang out if I wanted to. I figured she was a fun girl to be with and said sure, 'I'll do that.'
Sarah put her nephew to bed about 10:00 that evening. Her brother and sister-in-law were not scheduled to be back home until 2:00am. Around 11:00 Sarah I were cuddling on the couch and she looked me in the eyes and said 'do you want to take a shower with me'? I again was caught off guard, but answered 'sure.' She grabbed my hand and led me to the bathroom.
Once in the bathroom Sarah peeled off her shirt and pants, then turned to me and said 'come on you cannot shower in your clothes.' I pulled my shirt off as she undid my jeans. She turned her back to me and said, 'undo my bra.' I did just that and she took off her panties and turned around again and pulled down my briefs.
By this time I was sporting a hefty erection and the water in the shower is running warm. Again Sarah grabbed my hand and this time she pulls me into the shower. There I was nude and in the shower with a girl I'd only known for a few weeks. I had never done anything like that before. Sarah starts to scrub my back. She asked if I liked it and I said 'yes.' Pressing her body tight to mine, she reached around and started to soap up my penis and testicles.
All it took was a couple of minutes of her washing me to make the semen fly. I withered in her arms when I came. I turned around and Sarah planted a deep kiss on my lips and then said 'when I shower with my nephew it's not, like this.'
