``When you have sex, the hymen regenerates and the vagina gets blocked.'' A lie told by her brother causes her ignorant sister to go wild! I thought it would be bad if it got blocked, so I inserted my brother's dick without permission! The younger sister who has found out how good she feels is so absorbed that even when her older brother says, ``I'm cumming!'' or ``I'm already ejaculating inside of her!'', she doesn't even notice and continues to drive the piston! She completely skips the creampie and accelerates the movement of her hips without worrying about the overflowing sperm!
