"OK, look," said Erby, looking over at Cerby. "We are sort of just the one person right now, so if I'm feeling really horny, you're just going to have to deal with being really horny. And thanks to this one messing around a while back," she pointed at Erus, "I get horny a lot." All three paused a moment as Erus mashed her huge breasts together while lightly pinching each of her nipples between her index and middle fingers. "Especially if she's gonna keep doing that."
The merged beast stepped over to a nearby bed, briefly attempting to lay down on it before noticing that wasn't especially viable with their current body plan, instead just leaning on it as their middle head continued. "So, you're just going to have to indulge me a moment here..." She slowly slid her hand down her taunt furry stomach, smoothing down her fur and spreading her fingers such that two would be ready to do their thing as they passed down below her belly button and the point where the three torsos merged to sensually stroke the... large tuft of fluffy fur essentially covering a fourth chest between their shared forelegs. "Oh, right," she said awkwardly, bending forward to try and reach further, to the feminine slit situated behind their shared back legs.
Quickly realizing her arms were decidedly longer than the confusing mess that was their collective spine, she turned to the others. "Hey, can you reach back-?" Cerby returns a look of absolute shock and disgust, along with a slap that all three felt across Erby's cheek. Erus was more willing to give it a shock, taking one hand off her breasts and doing her best to lean around as Erby awkwardly walked them about in a circle, but she fell quite a bit short as well.
"Well this is a serious fucking problem!" Erby shouted.
Cerby gestured around. "Aren't you a bit more concerned about our apartment burning down around us!?"
Erby shrugged. "I guess there is that. We're probably fine if we're hellhounds or whatever? Or, a hellhound? But yeah, we should probably go."
Up rose the large shared dog body, headed for the front door, with Cerby quickly grabbing her (their?) cellphone to try and document things, Erus still distractingly playing with herself, and all three having a terrible time actually getting through the door, with many a shoulder and forehead banged, and breasts squeezed a bit uncomfortably. The elevator ride down to the street was almost as bad, but eventually the three stepped into the cool night air on a rather empty street, trotting briskly in the opposite direction of the incoming fire engine, whose sirens were loud enough with everyone's now much more sensitive ears for the three to all clutch their heads and howl about it until they'd put some distance behind them.
Wandering about with no real clear goal beyond finding some sort of sexual release, Erby turned to Erus and said, "hey, so this is all awkard as hell, and I don't mind just kinda yanking the wheel away from the stick in the mud here, but we used to be the same person and you're just kinda stuck with us and that seems kind of unfair if we have to like vote on something, so uh... speak up if you care where we're going? Or like, ooh! Which one of them should we have our way with first here?" Their shared tail started wagging as Erby pointed at a trio of guys who'd clearly been out drinking a while. One seemed like a real gym rat, one the sober designated driver, and the third so absolutely trashed he didn't seem to even know where he was.
Cerby cut in. "What? No! It already feels like pushing it to be wandering down the streets as this weird freak, and stark naked at that, but aside from everything else wrong with that idea, I'm quite sure we'd be arrested for assault!" She waved her hands towards the trio of humans shouting "hey! You should get out of here! My crazy sister wants t-" Erby reached over with both hands to clamp her mouth shut.
