I was going to take off from ZZZ to fly over to ZZZ1 for the night for hangar availability. The wind on the sock was almost a direct crosswind with the occasional gust and it was favoring Runway XY for departure. It had just started to rain before I turned on the engines. When I taxied out to the runway and performed my run up; everything was in the green; and the plane was good to go. I applied flaps for short field take off and held my brakes while applying power. With approximately half the runway remaining I aborted the takeoff. I chopped the throttle and applied braking action while getting the flaps up. I realized the plane was not going to stop on the runway because of how slick it was and the tires kept sliding. I cut the mixture as well and the props were windmilling as I slid off the end of the runway. The plane continued to slide down the slope on the hard dirt before coming to a rest at the fence where the prop made contact with the links.
PA-23 Pilot reported sliding off the end of the wet runway after losing control of the aircraft while aborting a takeoff.
