With a sex drive of 9/10, what else was Ben gonna do? He didn't have time to go out into HIS new world, he had to get the important business done first. Ben had to admit that he mainly did this just to fap. But enough with the thinking, it was fapping time!
Ben was eager to do this but there was 1 problem. He couldn't reach his dick. It was all the way in the back. Even at full length, he couldn't get to it. Ben couldn't wait any longer. He had to fap! So logically, the next option is to find something around his house that he could use.
Ben had to think for a moment but then got the idea. It was minimalistic, but it would work for now. He'd ram his dick in between the couch cushions.
And with that, he quickly galloped away to the innocent and unsuspecting couch. He got up on it with his 2 front hooves on the seats and his back hooves on the ground. His torso was free to do anything. He pulled up some good porn, got hard, and started humping away.
Ben felt very weird doing this. Of course he masturbated before, but fucking a couch as a centaur was a little different. Despite that, it felt REALLY good. His dick felt powerful and ginormous. He was clenching his teeth and felt like this was the experience he'd been waiting for his whole life.
The climax was coming soon and Ben didn't know if he could handle it. He could feel it coming and it was big. He was on the brink of holding back, but he kept going.
He finally came. He was instantly struck by an explosion of pleasure that instantly knocked him out cold. He came all over the place. Now I don't want to look like an ass hat, but you could probably call that a CUMSPLOSION.
