(CNN) Two women say an Uber driver kicked them out of his car after he saw them kiss in the back seat. The driver's taxi license, required to drive for Uber in New York City, has been suspended as the New York City Taxi and Limousine Commission investigates what happened.

Alex Iovine, 26, and Emma Pichl, 24, live together in Manhattan and have been dating for nearly two years. The couple was heading back to Manhattan on Saturday after celebrating a friend's birthday at a Brooklyn bar. Iovine says she and her girlfriend were sitting on opposite sides of the back seat when they kissed.

"The middle seat was open. We were just having a conversation throughout the ride and, at one point, we leaned over into the middle and peck-kissed," Iovine told CNN. "That's genuinely all it was."

Uber lists community guidelines on its website, which specify that "you shouldn't touch or flirt with other people in the car," and that there's "no sexual conduct with drivers or fellow riders, no matter what."

But both Iovine and Pichl say they kissed once, and were not touching inappropriately.
