Today, as usual, the sister licks her brother's entire body until it's covered in saliva and straddles his erect penis to induce internal ejaculation. She eagerly sucks on the sweaty cock, drawing out its pre-cum, and uses her saliva like a faucet to make his penis and face glisten. The brother with twisted sexual preferences initially resisted but once his perverted switch is flipped, he licks every inch of his sister's body and thrusts his hard penis into her bare vagina. They engage in intense intercourse, sucking on each other's tongues, and today she receives a full load of his semen deep inside her womb.
