This is a continuation of the linked story, and involves the relationship between myself and my female cousin.
After my orgasm, I began to work on Dee's pussy as she directed, but being a clumsy 15-year-old boy, I thought that I should simply thrust my fingers in and out of Dee's vagina. She tolerated this for several minutes during which I could feel a slippery fluid gradually begin to flow. Suddenly in exasperation, she said, 'You're not doing it right. You have to rub my clit in circles.' Then she took my forefinger and moved it in circles around a little hard button at the merger of her inner lips, and said, 'The hard button is my clit it is like the head of your penis. Rub it in circles.' I did as she said, and after about a minute of this, I added my second finger rubbing so that her clit was between the fingers. She sighed deeply, and said, 'That feels so good. Keep doing it that way, and I'll come.' I kept going, and she began to raise her behind off the bed, open and close her legs, and breathe heavily. Then her whole body suddenly got stiff as a board, I could feel her pussy throbbing, and she gasped, 'I'm coming, I'm coming, Oh God.'
This was the first time I had ever been with a girl when she came, so I was surprised and a little frightened at the force of her orgasm. But like myself and the other boys I had seen have orgasms, she survived. Really she thrived. When she relaxed a bit she said, 'Hold me tight and kiss me.' With a little hesitation, I did. Soon she noticed I was hard again, and without my saying anything, she began stroking my penis again, and I had another orgasm. By then we were both gloriously satiated, and as I held her, she asked, 'How did you learn about jerking off?'
I gave her a quick history of my pecker pleasure, but that is another story.
