"You just have to be my horny sister" Rebecca said. "What?" Cinnamon asked confused while Rebecca was taking off her clothes staying in the nude in front of her. Her now big sister answered "I've to confess that I allways loved you. Now is time to have that sex I always dream for us". The 14 years old girl was more and more confused "But Reb... If you loved me... why two years ago when I asked you to be my girlfriend saidyou saw me just as a friend?"
Rebecca giggled "it's cause I'm lesbian. It's for that I've suggested Kim to leave you a girl... I know you too well and I knew exactly that you would react like this making Kim furious. But now stop explanation" and immediately she kissed Cinnamon and then touched her breasts. This was so strange to her...but was also fantastic! Rebecca then bended down and started licking Cin's pussy for 20 minutes, untill she was wet. Then Cinnamon decided to be a "good girl" and gave the same service to her "sister". When also Reb was very wet, they lied on the floor. Suddenly Rebecca got a finger into Cinnamon pussy, and then a second and, while the younger whezed for the second orgasm, the older was kissing her tits.
They had sex for three hours and was their best sex in life (thill that moment). At the end Rebecca asked "so sis, what do you think?". Cinnamon laughed and said "I think that Kim has forgotten that wanted me to be heterosexusal" "you can say it aloud... and what do you think about being a girl? Are you still angry with me for have inderectly made your transformation during forever?" "this is the best thing that happened in my life" she answered and then asked "but we are sister now... we shouldn't have sex... should we?". Rebecca giggled and said "people think we are sister... but we know perfectly that you are my bitch and I'm yours... And obviously we will have sex every day, 'young lady' " Then they kissed and had sex for another hour. At the end Rebecca dress herself again and said "now put on that dress and be so feminine as you just demostrated to be... then come in the kitchen so you can help me to make the dinner to 'our' parents... this night before going to sleep I'm giving you a lesson on make-up, so you can make it by your self when you'll start school again in a month" and smiling went to the kitchen.
