Sônia and Julia are friends but as Sônia is bigger and older and Julia has a more delicate appearance, small and thin, they joke that they are mother and daughter. Both have thick legs and a big ass, but Julia is shorter and has smaller breasts and Sônia is bigger and has big breasts. Sônia always calls Julia baby and Julia calls Sônia mommy. Julia loves to moan, calling her "Mommy", as if pretending she doesn't believe it because she feels so excited and calls out to her between moans.
