Seeing as you're stuck here until someone shows up, you decide to get a head start on explaining the situation to Pedro, and begin typing up a sloppy version of what's happened to you. You get a few sentences in when you're surprised by a dropping feeling in your gut. It's the same feeling you had last night. Another egg is coming. Unfortunately, the feeling startles you, and the phone falls out of your precarious hoofgrip. You clench a previously-unknown muscle inside you to try and hold the egg in while you reach out to try and grab the phone, but after a few moments holding the egg in you feel a sharp pain and have to let go. The need to lay the egg takes over, although it's not as overwhelming your second time through. This time, you're more lucid, and you concentrate on the pushing and relaxing you do to move the egg out of you. You can feel the pressure of the egg passing through you, you're pretty sure that whatever patchwork anatomy you must have internally isn't really made for an egg of this size. It's almost uncomfortable enough to hurt, but not quite, and as you pass it through you there's also a feeling of relief and satisfaction.
Then you feel another sensation, centered on your head and arms, and this one's new. It feels like you've just taken off a heavy sweater you've been wearing all day. During a lull in the egg laying, you look down at your arms, just in time to see the last of the latex slip off them, leaving behind what looks like a living, fleshy pig arm. You can't see it, but you're pretty sure your head just got the same treatment. You've run out of time, the glove is finished converting your barnyard-mashup body into real flesh and blood. You were so close. you can't believe you're running out of time now! Your squawk of dismay turns into a grunt of effort as the egg starts moving again, forcing you back into the rhythm of laying it. As you keep pushing, the latex slides off your lower body, and you feel your feathers fluff out. With a loud crow, you give a final push, and the egg is laid.
A feeling of ecstatic relief comes over you, and your worry vanishes into a pool of pure relaxation. This is only the second egg you've ever laid, but you have to admit you're starting to like it. If you manage to change back somehow, maybe you'll keep this bit... You adjust yourself on the egg as the last of the latex slides off your udder, collects in a pile, and comes to rest in a glove that covers your right hoof. After a few minutes of relaxing, you come down from your egg-layer's high, and the dread that this body might be permanent sets in. Mixed in with the dread is a small amount of relief that at least the stress is over. Reluctantly, you look over your new, and perhaps final, changes.
The "good" news is, you mostly look the same as before, but less shiny. You rub your pig arms together. If it felt weird to be made of latex, it feels even odder to have real skin. It's almost human, but not quite, and the sensations it gives off are mostly familiar. Looking downwards, your feathery lower half got the biggest change. The real feathers are far more downy and warm than the latex had been, and a part of you is actually grateful for this change, as even sitting down on the hard wood floor you're comfortably cushioned. The feathers tickle your udder slightly where it hangs down across your chickentaur lower body. Speaking of your udder, now that it's flesh, it's much harder to ignore how full it is. It feels kind of like you have to use the bathroom and you've been holding it in a little bit too long. You don't know what will happen if you have to keep waiting, but you think it's going to start hurting soon. A few experimental hoof proddings show that you still can't milk yourself effectively.
Maybe this is somehow still reversible. You can't remember the details of the instructions, could someone change you back to human? Your last hope is that your friend can somehow still fix this when he gets here. IF he gets here. You're pretty sure you heard your phone get a text while you were laying, but you can't reach it from where you're stuck sitting on your egg, so you have no idea if it was Pedro responding to you. You just have to hope he beats Curtis here.
