"What about them?" you demand impatiently, realizing that your ears HAVE been feeling sort of strange now that you think about it. You've been feeling weird muscle spams up there every time your dad says something, and his voice HAS seemed a lot louder and easier to pinpoint than it did when he started. You experiment with the restless muscles up there and feel the air rush past your ears in a weird way even though you're lying still on your side. Are your ears somehow ... moving?
Now that you're now longer so entirely focused on your impossibly realistic tail and your inability to remove that, you find the tail has relaxed a little bit and is now dangling limply against one of your knees. You flex it around on purpose a few times, both impressed and unsettled by your level of control over it. You soon manage to point it directly behind you, allowing you to comfortably seat yourself upright once more. Your tail still aches a bit from when you pulled on it, but you are able to ignore it and focus your attention on your ears. Summoning your new muscles into action, you feel your earlobes stretching and opening wide in a way that makes the computer noises from your father's Chronivac much easier to hear in front of you. You were already looking in that direction, but somehow you've made your ears look at it, too.
After a moment, you feel a wobble up there and realize you can refocus your ears in more than just one way. Keeping your right ear steady in the way that easily picks up the sounds in front of you, you let your left ear drift a bit. To your left, there's a door to a vanity bathroom (one of dozens in the mansion) where a faucet is dripping. The dripping keeps getting louder in your left ear while the computer noises are still beeping into your right ear, until at last you are listening in both directions at the same time.
"I bet your hearing is REALLY REALLY good, now," says your dad in front with a prideful look. Instantly after the first word, your left ear jerks and then you hear him equally well in both ears at the same time. At last, you build up the courage to reach up and try to feel what happened to your ears!
The first thing you notice is that they're furry--not long and silky fur like your tail fur, but more like a fine fuzz that still covers all of the skin up there. The second thing you notice is that they're big. You have to feel around a bit to get a sense of how big they are! They're fairly tall and also rather wide, like big triangular satellite dishes. The third thing to notice is that it's kind of hard to keep them still while your groping them like this. They flail around on their own making it hard to get a decent grip on either of them! The fourth thing you notice is that patting the bare skin of your hands against that fuzzy fur feels rather nice. That feeling gets even better as you move a hand inward closer to the center until you reach a narrow point between them on your head. That feels REALLY good! You shove your head against your hand and feel your tail begin to twitch. You feel around your scalp bit to narrow down the exact best spot and can't resist thrashing your tail around wildly, thumping it against the bed with reckless abandon. You don't even try to stop it from wagging, in fact you even enjoy the comforting rhythm that vibrates up your spinal column. All you can do is groan from the pleasure.
"Enjoy those human hands of yours while you have them," says your dad with barely contained ridicule in his voice. You stop rubbing and let your ears perk up to hear him. "You might be the only dog who ever got to scratch himself behind the ears like that!"
Oh shit! The dog thing! You completely forgot! You can't believe you just completely lost yourself to animal pleasure for like a minute as though you really were a dog. You stop wagging your tail and start thinking you just have to see what your ears look like. You jump up, run to the bathroom with the dripping water, stare straight into the mirror, and wobble back in shock. They really are dog ears. Almost like wolf ears, but probably bigger. They're like German shepherd ears. And yes, you can flex them even without thinking about it. Your right ear twitches toward yet another snide comment from your father who is still by your bed. Someone walks up to the front door on the other side of the mansion and rings the distant doorbell, and your ears perk up to hear it.
You want to think your dad put fake dog ears on you during the night, but it isn't possible. Nothing fake could feel that good. Nothing fake could react that seemlessly to your sensory needs. Your ears flatten against tighten your skull. Your long tail dives between your legs again. They're yours. Soon everything a dog has will be yours! And when it's over, your wealthy father will be perfectly content to let you literally work like a dog for the rest of your days.
