This happened many years ago but we still enjoy it. My sis and I are two years apart and have always bathed and slept together so there was no secret about our bodies. One school play had a song in it about jeanie with the light blonde hair. which was the theme song. A few weeks later we were laying in bed after lights out and that song came up and I was teasing Jeanie (which is her name) about having no hair as I had a fair light bush. We were teasing each other but had not put any PJs on yet when she began feeling of my pussy and the inside of my thighs remarking about how smooth they were and I returned the favor by feeling of hers running my hands all the way up to her pussy. Soon we were laying 69 to give better access and were enjoying the closeness when and the light massage when she laid her head on my left thigh and said I smelled good and brought her lips close and kissed me right on my pussy. It shocked me and for meanness I kissed her on her pussy. I didn't know about her but it gave me as strange exciting feeling and I kissed her again and she did me too. For the next few minutes we kissed each other over and again unti both of us were wet and the perfume smelled so great that I stuck my tongue out and licked Jeanie and she let out a small gasp and started licking my pussey and I couldnt help but lick hers harder and stuck my tongue out and got it in her hole as far as it would go. For the next hour or so we licked and stuck out tongues in as far as they would go until my hips began to shake and I guess I had my first orgasm. After I aly there a few minutes catching my breath I went to work on Jeanie and soon she has the hip shaking reaction. We had both enjoyed the experience so much that after we had rested a few minutes we went for each other again and again for the rest of the night. Mother wondered why we were sort of groggy for breakfast but we just said we had talked too late. That morning when we went to pee it burned a little but that feeling soon left and that afternoon when mother went for groceries we strippped off and got in few more sessions as we couldn't wait for bedtime. We kept it our secret unti the next sleepover party where we showed four other girls the wonders.
