Title may or may not change, I couldn't think of anything good. Meant to have a second part submitted at the same time, but this has taken long enough.<br /><br />First, a huge bit of thanks to <a target="_self" href="https://deliciously-idiotic.deviantart.com/"><img class="avatar" src="https://a.deviantart.net/avatars/d/e/deliciously-idiotic.jpg?3" alt=":icondeliciously-idiotic:" title="deliciously-idiotic" /></a>, who did a sizable chunk more than I expected helping out with the transformation part that had caused this to take so long to complete. His contribution starts a bit before the transformation, so the writing looks like it changes styles, that's why. Go check his stuff out, he's a great writer, and better than me in my opinion.<br /><br /><br />But anyway, this is a bit different from my usual stuff. It's more like xenofiction exploring this thing's biology and adaption to his new form set off by the transformation, and there are more parts incoming that have been planned out.. Most notably, there's nothing fetishy here unless you're into leeches for some reason, so if you came for the usual stuff, you might want to back away for a bit. Plenty of that everywhere else.<br /><br />This commission is brought to you by <a target="_self" href="https://jwargod.deviantart.com/"><img class="avatar" src="https://a.deviantart.net/avatars/j/w/jwargod.jpg?1" alt=":iconjwargod:" title="jwargod" /></a>, who also proposed some more straightforward TG-TF stuff. For some reason I went with the freaky alien leech. Hmm.
