Thomas Goodman “permanently scarred” the youngsters during the six-year reign of depravity in Rhode Island, US.
A court heard he also filmed himself molest a baby on various occasions from when she was three weeks old until she was 18 months.
He shared some of sick footage online.
But disgraced Goodman fainted at Rhode Island Court on Friday after a disgusted judge condemned the acts.
The sex offender was caged for 260 years, some 160 years longer than the prosecutor had asked for.
Sentencing, Judge John McConnell said: “The level of depravity is beyond comprehension.”
