A German couple was tossed behind bars for 12 years Tuesday for selling custom-made online videos of them sexually abusing their son.

The 48-year-old mother, Berrin T., and her boyfriend, Christian L. — whom the boy called “Papa” — charged several thousand euros to film each instance of abuse and upload them on the dark web, the UK’s Telegraph reported.

Berrin was sentenced to 12½ years in prison while Christian received a 12-year sentence in Freiburg state court. They also were ordered to pay $49,200 in damages to the boy and a 3-year-old girl whom they also abused.

Christian, 39, the boy’s stepfather, must remain in preventive custody after serving his sentence.

They were only identified by their first names and last initials as per German privacy laws.

The twisted pair and six others were part of a pedophile ring that was busted last year following an anonymous tip.

The couple admitted sexually abusing the now-10-year-old boy themselves for at least two years. The mom said she went along with the abuse at first out of fear of losing her boyfriend — then later for “financial motives,” the judge said.

They were found guilty of rape, aggravated sexual assault of children, forced prostitution and distribution of child pornography following a two-month trial that began in June, according to BBC News.

The disturbing case sent shockwaves through the country as authorities were accused of failing to protect the boy. Christian was supposed to be barred from having contact with children and the boy was removed from the couple’s custody in March 2017. A local court, however, returned him to the family weeks later.

The boy is now living with foster parents and is doing well “under the circumstances,” his lawyer said Tuesday.

On Monday, the same German court sentenced a Spanish pedophile, Javier Gonzalez Diaz, to 10 years behind bars for paying the parents to sexually abuse the same boy over and over again.

Diaz, 33, was ordered to pay the boy more than $20,800 in damages.
