Marie and I started kissing each other when we were both fifteen. It started at a sleep-over when six of us girls took turns tongue kissing each other. I thought that Marie was the best kisser and she had the fattest lips. About a year later we progressed to fondling each others tits outside of our tops. Shortly afterward the tops came off and we added sucking each others nipples to our experiences.
For the past year we have removed all of our clothes several times as we made out. Marie likes me to put my hand on her pussy and to rub the outside of it which is completely bare but she won't let me rub the inside and she won't let me finger her. She won't do those things to me either. Several times I have put my finger inside but she grabs my hand and pulls it away and tells me to stop it. When I ask her why she doesn't want to do more she just says 'I just don't.'
I can't begin to tell you how frustrated I get. There is no relief sexually and I almost want to cry. I'm thinking of telling Marie that I don't want to have any type of sex with her because of her unwillingness to bring me to orgasm or to allow me to do the same for her. Usually that same evening I will climb under my bed sheet and fondle myself until I finally cum.
I know it sounds pathetic but that's my story.
