While the remarried parents were on a trip, the younger sister, who is usually treated like a child by her older brother, was playing with her older brother when the older brother reacted to her panty shot. While the younger sister was teasing her, she made her brother cum with a deep throat blowjob, saying, "I can make you cum like a big brother!" The older brother was still excited and pushed his sister down, but the younger sister was also excited and they continued to have sex as if they were devouring each other.
