When a young teen needed help with higher mathematics, her sister immediately turned to her stepbrother with numerous requests. The cunning brother wasn't so simple, as he planned to profit from his sexy relative in exchange for her help. At first, the brother was surprised that his dimwitted sister had managed to get into a prestigious university, but later realized the situation would work to his advantage. The clever young man quickly approached the depraved cutie and, after a blowjob, began to coax his sister into family sex. At the end of the incestuous encounter, the beauty knelt to suck out every last drop of sperm.
