My older sister had moved back into our parents house while her husband was overseas working with an oil company, I was a senior in high school at the time and still living at home. Carrie was about six months pregnant and had quit her job when she got pregnant at her husbands request. He had asked if she could move back home while he was away just in case something happened to her. So she was around all the time. She slept on the couch more often than not because she said it was more comfortable. Every morning when I came in to get a shower and get ready for school there she was. Mom and dad were already gone to work by the time I got up, and since I lived above the garage I had to come inside to shower and such.
I noticed a few things about my sister in the first week of her staying, things that led to a big change in our relationship. First was the fact that she was no longer wearing underwear of any kind. She was to the point where all she wore was really loose shorts or those maternity skirts, and since she wasn't going anywhere she didn't wear a bra either. Laying there on the couch every morning I never knew if her pussy and ass were going to be exposed or not. I got to a point that I would peek every morning. I was fascinated by her body. I had a girlfriend but didn't have a super-sex-life, and the close proximity to a mostly naked woman aroused me- even if it was my sister. I grew bolder and began to feel of her a little before going to the shower. She had a nice round ass, big tits with nipples that seemed hard 75% of the time, and a semi furry dark haired snatch. Her legs were half shaved, as it seemed her pussy was, I found that odd, and interesting at the same time. It wasn't long until I understood why. That was also when I found out that big sis had a slight obsession about body hair.
It was a Monday and I decided I wanted to ditch school so I didn't bother to get up until almost ten that morning. When I shuffled into the house Carrie had already got up so I didn't get the peek I had come to expect each morning. At least not from her laying on the couch. I walked into the bathroom without thinking and there was my sister in my robe trying to shave her legs. She was having a hard time of it and I could see that she had gotten so frustrated that she had cried already. When she looked up at me my heart melted with sympathy. I said, "Why don't you let me do that?" She smiled weakly and nodded, "I guess I'd better, I'm not able to do it like I used to and the hair is just driving me insane."
So I motioned her to sit on the stool we had in there and I knelt beside her and lathered her legs up again with shaving cream. I began shaving her legs while she watched. I did the outsides of both legs and then positioned myself in between her legs to do the insides. She slowly opened up for me and before long I had one leg propped up across my knee as I knelt, making her legs spread open for me. I shaved up both of her inner thighs until I began encountering wild grown pubic hair on both sides. She was sitting there, leaned back and her legs spread wide open for me. I was hard as a rock. I had knelt so close that I could smell her pussy. I was breathing in her scent. I had walked in just after her shower so her scent was nothing but arousal now. It was enough to almost make me feel drunk.
It was probably because all the blood in my body had gone to the wrong head. I tried to think of her as my sister and all that, but it didn't matter to my cock. We looked at each other several times while I shaved her, but said nothing. We smiled a lot and that was about it.
When I had finished her legs and rinsed them off with a wash cloth she was smooth from ankle to crotch. She cooed appreciatively as I ran my hands up and down her legs, 'checking to make sure I hadn't missed anything'. But then it left us with the question of her pubic hair. I looked down at her pussy, which was right in front of me, and then up at her, "Do you want me to take care of this too?" She blushed slightly and nodded slowly.
