My name is Amy I'm 18, and I live with my sister Jess and our Mom Annette. Last week we were all going to go to a movie, 'Four Christmas''. I was running late because I had stayed at school to work on a group project. When I got home Jess (16) was in the shower, and I needed to take one before we left. I yelled up at her to get out, and my mom said she had just gotten in.
I went upstairs and opened the door to the bathroom, to ask if she would be getting out soon, she said no. Then she surprised me by saying it was fine if I got in with her, since we were in a hurry. I thought about it for a second, but what the hell, we're sisters, so I got undressed, and stepped in.
I hadn't seen my sister naked in a couple years, and there she was small breasts, and a rather hairy pussy for someone of her age. I could tell she was looking at me as well, while I was scooting towards her to get under the water. I was practically touching her when she complimented me on my 'boobs'. I didn't know what to say, so when I turned to grab the soap, and brushed up against her, it felt like electricity running through me.
The next thing I knew she was hugging me, and saying she felt it too. After that it became instinct, her hand reaching for my furry pussy, and mine doing the same to her. After Jess gave me the most amazing orgasm of my life, and I returned the favor, we promised to do this again, and we have.
ps: the movie was ok.
