O cunhado nunca fez sexo, fala com a cunhada, então a cunhada disse, eu te ensino como fazer sexo e o cunhado e a cunhada fazem sexo juntos.

The brother-in-law had never had sex, speak to the sister-in-law, then the sister-in-law said, "I teach you how to have sex" and the brother-in-law and sister-in-law both started having sex together.
