I've been thinking recently about what it would be like to lose your virginity to different kinds of monster. How the different characteristics of each species would make the experience different:
The manipulative werewolf who swears his cock isn't as big and painful as it looks. By the time you realise he's lying it's already stretching you to your limit and he wants to go even deeper before he knots you.
The vampire that feasts on the blood of virgins and wants to savour the taste. You're covered head to toe in bite marks before he'll even touch you.
The alien scientist that tunes out your moans of pleasure because it's only fucking you to loosen you up so the probe will go in easier. To make them touch you, you have to lie and pretend that whether or not you cum will affect the experiment.
The zombie that barely remembers how to fuck, it just knows it wants to. You have to guide it through the whole thing because despite your inexperience, at least you know which holes are meant to get fucked.
The beautiful hellspawn demon tasked with tempting and corrupting the innocent who enjoys it a little too much. You could get off to just his voice, so when he's whispering in your ear and sliding a claw under your chin it's only his powers that stop you from cumming in your pants.
I'm honestly tempted to post all these scenarios in full. Let me know if that's something you would want to see. Please specify gender of reader.
