This scene came from her early career, when she was very curvaceous. As time went on, she slimmed down.
Here’s a quick nudity timeline. Unfortunately, most of her early films seem to have been ignored by the digital age.
1980 – Nefali
1981 – C’è un Fantasma nel mio Letto (the .gif linked above)
1982 – National Adultery
1984 – Playboy en paro
1985 – El Rollo de Septiembre
1987 – El Bosque Animado
1992 – La Mujer de tu Vida 2
1994 – La Leyenda de la Doncella
She had lost her youthful curves in those last two films, but upped the nudity level by starting to do full-frontal scenes.
According to her IMDb page, her career is still active. She appeared in a 2023 short, Lo que más duele.
