While my remarried parents were traveling, my younger sister, who is usually treated like a child by her older brother, was playing around with her older brother, and the older brother reacted to the younger sister's panty shots. - While the younger sister is playing with it, she makes the older brother ejaculate with self-deep throat, saying, ``I can make you ejaculate as much as my older brother!'' - The older brother doesn't lose his excitement and pushes the younger sister down, but the younger sister also gets excited and continues to have sex with each other hungrily.
