An 84-year-old New Yorker's date with two 17-year-old twin sisters ended with the senior citizen tied up and robbed, according to police. The New York Times reports that Paul Aronson met up with 17-year-old Shaina Foster last month through SeekingArrangement.com, a sugar daddy site that bills itself as a place “where beautiful, successful people fuel mutually beneficial relationships,” according to the Times. After a first date, Shaina brought her twin sister Shalaine along to the second.
