Learning to Masturbate

I was an extremely innocent girl. When I was 16, I had not even had a boyfriend or made out with anyone yet. 

I stayed in a boarding school where we shared rooms with 5 other girls. You may think that this story is about masturbating with roommates, but it isn't. 

Each boarder had a mentor, who taught us various subjects at school. when I was 17, during health education, we were learning about sex and masturbation. It was assumed that most of us already knew what it was so it wasn't really described in great detail. I didn't know what it was though (told you I was innocent). I was super curious as to what it was, so later that day when I had the chance, I asked my mentor what masturbation was. She looked at me super shocked like she couldn't believe that I didn't know what it was. She told me, "It's touching yourself," and I asked her, "What do you mean?"

Her eyes were filled with pity and she could not believe I had never played with myself before. I asked her, "Can you help me, please?" 

She told me, "Sure, if you really are sure that you want to do this." 

I told her I was sure. She led me to the bathroom, and told me to take off my clothes. Thinking she meant just my shirt and shorts, I took them off and stood in front of her in my bra and panties. I was tall, had blonde hair and blue eyes, and had large breasts about a 36D. Her eyes went wide seeing my breasts. She told me to unclip my bra and take off my panties. I was a little unsure at first but then I thought "what the heck, who cares". In a second all my clothes were on the floor and she was staring at my breasts and unshaved pussy. 

I sat down on the toilet, and she told me she was going to masturbate me. I said, "Ok, im ready." She touched my clit which was already super tingly and kind of hard. And with her free hand, she started caressing my breasts and squeezing my nipples. I was sooo turned on and everytime she touched me I felt electric tingles everywhere. I didnt want her to stop and let out moans. Before I knew it, she had her finger in my vagina and I suddenly felt a totally new feeling, like I was going to pee but not really. I told her, "Stop, stop, I think I need to pee."

She replied, "No, just hang in there a while more and trust me." I didn't say anything else, but 3 seconds later I had my first orgasm and it was so strong my hips bucked and lots of cum just started flowing out of my vagina. I started getting super worried but my mentor was like, "It's totally normal you dont have to worry." 

I thanked her profusely for showing me what it was. AFter that, she continued to masturbate me frequently!
