as a result of continuing to rub and play with my younger sister's breasts since she was young... when i continued to touch the breasts of my younger sister who was just cute and timid since she was little, her reaction changed from "ticklish" to "feels good"! when i thought my younger sister's reaction had changed, she suddenly looked so cute that i attacked her! moreover, i even forcibly creampied my younger sister who didn't like it!! i thought it was really bad and was regretting it... but then she said she wasn't satisfied and attacked me this time... and it developed into even more intense sex!
