His little sister asks for help and fucks him to get what he wants

When this aunt wants something, she strives to reach it anyway. The bitch herself is considering running for election at her institute and needs her brother's help to end up becoming the most popular. What he does is ask the favor in a very convincing way: fucking him. Her little sister has a great body and is very good, both in lingerie and the moment she undresses and eagerly eats her brother's cock. As soon as they start fucking, they play an incestuous and bestial void that ends with their brother running.
