"Now don't ya worry deary," the boar grunts as he positions himself on top of you "Everyone is afraid at first. But then before ya know it ya start ta enjoy it! And by then ya wont think of anything else ya would rather do than spend the rest of yer life as a sow in my harem.... Of course, its not like ya would have much of a choice by then." The anthromorpic boar says, trying and failing to calm you down.
But by then he has finished positioning himself and with a single powerful thrust he rams his thick boarish cock deep into your anus.
"Don't" Grunt "Worry. I'm sure" Oink "ya will make a fine sow," Snort "and birth many fine piglets." Sssqqqquuueeeaaaallll!!! And with that, the anthromorpic boar cums into your anus and begins to slowly slide his cock out of you.
"There now, that wasn't so bad now was it?" The boar man asks. "And once yer done transforming we will be able to do that any time! Your transformation should begin about.... now." Thats when you suddenly feel a strange (and slightly painful) churning inside yourself. It almost feels like your organs are rearranging themselves.
