i knew my sister was a lesbian, i'd always been curious but has never been with another woman, one weekend while are parents were away we were curled up together on the sofa, she was upset because she had recently broken up with her girlfriend, i asked her what she missed most about her and she said the intimacy, hearing about what they did together was getting me a little wet, and turned on to be honest, she asked me to sleep in her bed with her, seeing how upset she was in agreed immediately. We both sleep naked and while she was lying in my arms i was getting aroused, she looked at me and i leaned in and kisses her, not a peck on the cheek a long lingering kiss our tongues playing together, she asked me if i was sure, i was certain, she made love to me tenderly asking me if i was ok, i told her i had never been so alive, when she made be orgasm i shouted her name, i'd never been so loud, it was my turn to give her an orgasm, she guided me all the way, a truly wonderful experience, we woke up in each others arms, she asked if i had any regrets, i told her no, and started kissing her, i made love to her, she orgasmed and said welcome to the sisterhood
