She's always there, watching. Waiting. Just outside of your peripheral vision. Crouched in that dark corner, hiding in your closet, lurking under your bed... She is patient. Oh so, so patient. She watches for hours, sometimes days, even weeks. The dread builds. That feeling creeps and crawls over you like some sort of horrific blanket. She delights in it. She wants you to squirm.

And so she waits. She watches. She strokes. She touches. Never you, no, never you. She needs to earn that. Only herself. She leaves dollops of precum under your bed, but you never see. She drools in your closet, but you never notice it. She pleasures herself, edges herself while she watches but she never finishes. Not until she's ready.

Only when you can't sleep anymore will she come out. When the dread, the feeling of being watched is too much, and you sit there with your desklamp on, convinced that someone or something is in the room with you. Then, while you sit in fear, she climbs out of her hiding spot, cock harder than diamonds, and...

You don't remember her. You never remember her. All you do remember is sitting there one moment, then waking up. You must have passed out from exhaustion, but it was strangely the best sleep you ever had.

And a few days later you get the feeling you're being watched.

Hey, thanks for reading my shitty little horror porn prompt. I have the creeps tonight and I find the best way to conquer one's fears is to lewd them! So, I'm asking you fine perverts to play a monster girl with a big throbbing cock that watches until her quarry is going crazy, then fucks them to sleep. Over. And over. And over. I might actually fall asleep before replying, but I'll answer in the morning if that happens! Just send me a message with what your monster looks like (descriptions and refs both are welcome), and I'll take it from there!
