Testimony in the Nxivm trial turned steamy Friday as a witness described in graphic detail more than $900 in sex toys purchased by one of Keith Raniere’s alleged slaves.

The bevy of X-rated items included a hanging rubber strap cage for $299.95, studded rubber paddle and a remote “puppy trainer” that’s “perfect for puppy play or naughty slaves,” the witness, Sean Welch, testified in Brooklyn federal court.

Welch, the chief technology officer of sex toy manufacturer XR LLC, said the $922.74 worth of toys was delivered to Daniela Padilla, a member of the alleged sex cult’s secret society called DOS, at her Albany-area home.

They were purchased on the website Extremerestraints.com.

“These are not for puppies?” asked prosecutor Moira Penza.

“Yes,” Welch answered.

Padilla’s May 26, 2017, order also included a thigh sling with wrist cuffs — which Welch described as allowing “you [to] call the shots while your submissive partner is restrained and at your mercy” — and a “subdued” full-body strap set he said is used to “paralyze your partner.”

Two days later, another order in Padilla’s name was placed, this time for $1,730.90 worth of sex toys, such as a steel “puppy” cage, a wireless vibrating remote “puppy” plug, a “puppy” play hood with breathable ball gag and a bed restraint kit.

That order never went through, however, because of an issue with payment and shipping, Welch said.

Jurors had no visible reaction as they perused photos of the toys admitted as evidence in Raniere’s sex-trafficking trial, now in its second week.

Welch was not asked how — or if — the toys were used by the twisted upstate group.

“It’s 100% legal to buy these items?” asked defense lawyer Marc Agnifilo.

“Yes,” Welch said.
