Murillo, a dedicated student but facing difficulties in the entrance exam, receives an unusual suggestion from his friend: hire the former teacher at his school, who now teaches private lessons, Caio, a sensual and intelligent man. Upon meeting Caio again, Murillo realizes that his classes are not only about mathematics and Portuguese, but also about hidden desires and repressed passions. Over time, the teacher-student relationship transforms into something more intimate, exploring limits and discovering forbidden pleasures. When Caio confesses to being gay, Murillo, who also identifies, feels closer and begins a game of seduction that ends in a fiery encounter, where both give in to temptations and live a night of intense and limitless passion, in a swap full of putaria.
