You watch your tail flick back and forth almost automatically, though with some practice you manage to send it the way you want it to. Practicing the control of this new appendage is making you sweat...or is it? Your body is starting to feel damp with sweat and you think it must be the lack of air conditioning in here...until you look at your arm and see it's completely covered in fine white hairs! You put your hands to your face and feel the same kind of hair, as if a beard had suddenly grown all over your head. No longer able to take the itchy and warm feeling your clothes are giving you, you quickly take them off and notice your entire body is covered in bright white horse hair. Kind of embarassed about the fact that you're standing here bare naked you decide to keep on your underwear (although it's pushed down a bit by your tail) and walk around a bit, feeling amazingly comfortable wearing no clothes. You can quickly feel your underwear getting tighter around your butt though, so you eventually remove your last piece of clothing as well, but even naked your privates remain relatively unrevealed as your member has turned upwards into a furred sheath, but it has not reached appropriate length yet. You look rather skinny now though...
Your belly swells up and levels with your torso, swiftly adjusting your body mass to equine levels, and rubbing a hand across it it feels extremely pudgy, like an enormous blob of warm meat. Almost proud, you prance about the room showing off your new look...but it's not done yet. Far from it.
