I like that one with the monsterfucker knocking up the monster.
Gave me an idea for riff on the classic Knight saves Damsel story.
Gallant Knight (either Cismale or Transfem) goes on a quest to rescue the Royal Heir (AFAB Nonbinary). Finds the Heir in the Lair of a Beast. They're grotesquely pregnant with the Monster's brood. Their belly so big that it pins them to the ground and they can't get up on their own. Upon seeing the knight, the monster attacks to defend its brood, but the knight is able to beat it into submission. When the creature is defeated it submits to the knight and presents its posterior for breeding. The knight takes the invitation and fucks the monster long and hard.
Then, after breeding the monster, the heir begs the knight to fuck them to induce labor. The knight obliges, but it doesn't work. So the knight loads the very pregnant heir up in a hand cart and takes them along with the monster back home to the castle. The knight fucks both the monster and the heir every time they make camp on the return journey. So by the time they make it to castle they're basically a throuple or a polycule or whatever you call it. When they arrive at the castle the heir is ridiculously overdue with the Monster's brood and the monster is very pregnant with a litter of the Knights human babies.
When the knight presents the Royal Heir to the Monarch, that's when the heir finally goes into labor and births the monsters brood in front of the whole Royal court.
Anyway, that's all I got so far. I'd love to hear your thoughts.
the knight worked so hard to save the heir, and trained for their whole life to be strong enough to defeat the monster, of course they deserve to take the heir AND monster as their trophies <3 and maybe the heir birthing in front of the whole court inspires the king and queen to force the monster to do the same as a punishment for taking their precious child <33
