I was a pretty late bloomer for a girl. Up until I was about thirteen I had no pubic hair, and almost nothing in the way of breasts. But when I finally did start changing about six months ago, things started to change fast for me, and one thing I noticed was that I would have an increased urge to touch myself.
I had never had an orgasm, but since I was about six I would always lay in bed, and stroke my pussy because it felt good. Anyway, I started to get these urges a lot, for almost no reason, and I started to realise how good it felt to rub my clit against things.
Well, my 11-year-old sister and I would always bathe together, almost every night, and since we were brought up to be nearly totally ignorant about sex (we're home schooled but I take some classes at the middle school), she was very curious about my new soft pubic hair and my very large puffy nipples. After a while, she started to sort of feel my nipples out of curiosity, and I started to become horny. She giggled as they hardened, and I started to blush uncontrollably.
While she continued to play with my nipples, I started to involuntarily rub my pussy against the side of the bath. It felt really good, but soon we were done washing and had to get out of the tub. My clit was so excited by this time, that I could see it sticking straight out. By the time I got into my pyjamas, got to bed, and turned the lights out, I started playing with my sensitive nipples. I didn't understand the feelings I was having, but I started to uncontrollably hump the bed. My sister asked from her bed 'what are you doing?' 'I don't know, but it feels good' I replied breathlessly. 'Can you show me?' she asked. 'Ok' I whispered.
As she came over to my bed I said 'Play with my nipples again, ok?' 'Sure' she said, and started playing with the puffy mounds on my chest. The feeling between my legs built as I humped faster and my sister rubbed my chest more furiously. Soon I had to cover my mouth to keep from screaming as my pussy contracted and swelled into my first orgasm. It lasted for about ten seconds, as I lay there in bliss. 'What happened?' my sister asked. 'It felt really good.' I replied. 'Can you show me how to feel good?' 'I'll try' I replied, and began rolling her nipples between my fingers. 'Just rub your private parts against the bed' I said.
It took her longer than me, but soon I heard her pant and curl up in my arms. 'Wow...that feels really good' she said. Not long after this wonderful night, I started to get lubricated when I was horny. Soon my sister started to watch for a wet pyjama bottom at night to signify that we would be helping each other 'feel good'. I love the good feelings we share. I hope others of you with similar firsts will share them.
