I'm a 22 year old college gal who plays with herself every day. I discovered masturbation at around 8 years of age. Even though I'd never seen pictures or videos of sex, I instinctively began to hump my groin against things. It started one night when I was laying on my tummy on the bed, in a nightgown and panties. I was reading and all of a sudden I got the urge the hump the bed. I slowly started to rub my pussy back and forth across the bed, as it felt better and better. I kept at it, rubbing faster, pressing harder, for 20 minutes or so, making it feel better and better. However, I did not have an orgasm, though, only the feeling of a great sense of enjoyment and fun.

That was the first of many bed humping experiences. Eventually, I'd lock the door, strip down and hump the bed in the nude. Felt even better! Then I began to rub myself against pillows and climb right on top of large stuffed animals. However, I never thought of using my hands or fingers to pleasure myself. I had no idea about that.

My first full experience with the concept of using hands for masturbation (a word I had no idea about for years) didn't happen until I was 12 years old. This first experience was with a babysitter named Andrea.

Andrea was a very pretty girl from the area who had been babysitting me for years, who I liked very much. She was very friendly and fun. She always took time to talk and goof around with me. Andrea was 19, about 5'5", slim, curvy, long black hair and a nice bust. At the time, I was about 4'6", maybe 70 lbs., with short red hair, no bust and no pubes.

One night my parents went out and Andrea was called in to baby-sit me. We chatted and played board games for awhile, then I told her I was going to my room to read a book for school. She said ok and flopped down on the sofa to watch TV. Off I went to my room, where I put on my nightgown and lay down to read.

I lay on the bed on my tummy, as I usually did when I read. Well, the book, being one assigned for school, wasn't all that interesting, so my mind started to drift to a sex scene in an R rated movie I'd seen recently. Next thing I knew, I was feeling horny, and I began to rub myself against the bed once more. I did this for awhile, then jumped when I heard Andrea's voice say, "How you doing?"

She was standing in the doorway, smiling at me. I hadn't closed or locked the door as I'd only planned to read my book. At that age, I didn't know if she'd know what I was doing or not (I knew enough by then to know it was naughty), so I kind of froze, not knowing what to say.

"Enjoying your book?" she asked. She came and sat on the bed. She was wearing a t-shirt and jeans.

"It's ok," I said. "It's, you know, school stuff."

"Know what you mean," she said. "I hate homework. It really stresses me out sometimes and I need to relax." Here she smiled at me again. Then, to my surprise, she laid down on the bed, next to me, on her tummy. Her face lay on top of her hands and her eyes looked right into mine.

"Sometimes it's so nice to just relax..." She sighed and closed her eyes. I just looked at her. She was still smiling and looked so pretty.

Then, Andrea asked me to rub her back and neck cause she said she was knotted up with stress right now, from studying for exams.

I sat up and began to slowly run my hands up and down her back, over her T-shirt. I could feel the bra strap that went across her back and feeling this gave me a kind of grown up thrill. I began to wonder when I'd get boobs.

"That's good, Laura. Keep doing it. It reminds me of my boyfriend when he does it." I felt proud of this, that I was doing a good job. I began to put more effort into what my hands were doing.

Andrea sighed. "You're starting to turn me on, like my boyfriend does." A giggle. "... But keep rubbing, I like it."

I was old enough to know what the expression "turned on" meant; I'd heard it before on TV. I knew it had everything to do with how I felt when I humped myself against things. I started to get excited.

Soon, Andrea began to squirm and told me to rub her hard on her lower back. Then she spread her legs and began to lightly rub herself against the bed... just like I had been doing. My heart jumped! I knew right then that Andrea knew what I had been doing earlier.

Next, Andrea asked me to rub her inner thighs real good. I did so, and after a while I was clearly getting turned on and tingly in my pussy. I could feel it. I'd never gotten the feeling before without actually doing the humping. I started to breathe heavy.

Suddenly, Andrea reached back, took my hand and put it between her legs from behind, placed on directly onto her private area and told me to rub her there. She lifted her ass off the bed slightly to allow my hand easier movement down there. I felt so sexy. I couldn't believe it. Even though her pussy was separated from my hand by the material of her jeans and panties, I could still feel the warmth that was coming from it, feel that the area was becoming more moist. Then she bent her knees, lifted her ass in the air and got into what I know now as a doggie style position. I continued to rub her, trying to do as best I could. She began to moan.

This went on for awhile, with Andrea's face pressed onto the blanket. Then, suddenly, she got all shaky and let out a loud moan. I guess she came. My hand felt like it was on fire; it felt so hot from the friction of rubbing against her warm, tight jeans.

Andrea, rolled over onto her back and said, "Thank you very much! That felt wonderful." A pause. "Would you like me to return the favour?"

I didn't say anything, I was so nervous at that point, and a little scared, too.

Andrea ran a hand through my hair. "It's ok," she said. "I saw what you were doing earlier, how you were enjoying yourself. I want to help you make it feel even better." She smiled at me and I smiled back.
