Last month, one so-called "sugar daddy" flew too close to the sun when he took two teenage twin sisters home with him after meeting online. Those twins, 17-year-old Shalaine and Shaina Foster, were arrested for allegedly tying up and robbing 85-year-old retired lawyer Paul Aronson after they allegedly tied him to a coffee table in his East 38th Street apartment for 20 hours while they went shopping with his credit cards. Now, the twins have turned on each other.

"There's always that story of the good twin and the bad twin, who goes right and who goes wrong," defense lawyer Brian Kennedy told the Post about the incident. "​My client Sh​alaine was always going right but it seems she got caught up in something that was not of her making."

According to the criminal complaint, Aronson met Shaina on Seeking Arrangement, the popular sugar daddy website. When they made plans to go out for dinner on October 1st, she brought along her sister; they went back to Aronson's apartment, and after a few cocktails, the twins allegedly took out zip ties.

"He asked to do things I wasn’t going to do," Shaina told Detective Darryl Ng at the 17th Precinct after the girls were arrested on Oct. 21st, according to the Times. "He is ugly, old and disgusting. I tied him up. I took his money and left. He was starting to creep me out."

What were the things he asked? According to Kennedy, Aronson asked them about their sex lives. "Both girls were taken aback by that," Kennedy told the Times. He claims the girls started to leave, and Aronson tried to grab one of them: "This was an older man who was trolling these websites," he said, referring to a website specifically designed to help arrange dates between rich older men and young women. "He was trolling for young girls."

Both women have been arraigned on kidnapping, burglary and grand larceny charges; they face a minimum of 15 years in prison if convicted.
