A pair of gutsy women who were targeted by the same serial subway pervert are speaking out about their horrific ordeals — and how their quick-thinking actions helped lock him up.

Cynthia and Beatrice — who asked their last names be withheld — said they just hope subway masturbator Dennis Sacaza will stay away from other women now that he’s free to ride the rails again.

Cynthia, a 32-year-old social worker, said she encountered the deviant when riding the L train home to Canarsie from a late night at grad school in January 2017.

“[He] gave me that gut feeling like something wasn’t right,” she said.

“He was moving his hand … I noticed that there was a hole in his pants and he wasn’t wearing any underwear, so you could see everything.”

Cynthia bravely pulled out her cell phone and recorded the creep in the act, spooking him into getting off at the next stop.

“I was shaking,” said Cynthia, who notified NYPD transit police when she arrived at her stop. “I was shaking for days after that … I was furious.”

But Sacaza, 53, was hardly deterred.

About two months later, Beatrice, a 35-year-old Queens native, was riding a 2 train between Manhattan and Brooklyn when she had her own run-in with the perv — who sat right next to her.

“I look over and I see the defendant’s penis completely exposed,” said the divorce lawyer. “And his hand or his arm was hitting the side of my right leg.”

Beatrice was shocked into silence as she jumped up and moved to another seat.

“I’m a lawyer, so I speak up for people. I speak up in court all the time,” she said. “For me not to speak up for myself, I was kind of shocked.”

But she composed herself and, like Cynthia, snapped a photo of Sacaza, which she turned over to police.

In November 2017, cops caught up to Sacaza for a trio of similar alleged incidents in Manhattan dating back to 2016, authorities said.

Those cases fell through, but Sacaza was finally convicted in March 2019 in Brooklyn for his run-ins with Cynthia and Beatrice.

Sacaza was released in May, having finished his 180-day sentence including time served — and with no laws prohibiting serial sickos from returning to the subway, he is free to ride again.

“I do believe in justice,” said Beatrice. “Hopefully he’s given the justice that he deserves. And then hopefully he will be off the trains and not doing this to some other person.”
