Monster in the Closet [F, fantasy]

I always knew monsters where real. When I was little mum and dad would shine a flashlight under the bed and in the closet to prove it, but that just meant the monsters knew how to hide good. Eventually I just stopped saying anything. Then I actually saw one for the first time. Oh my God. It was beautiful. In the dark it's long, curly hair wrapped around my wrists and ankles and pinned me down while it silenced my screams with a tongue that made my cunt drool. I was only 14. What could I have done?
Now I call it Daniel, and it's still beautiful. It still has its long hair and an athletes physique, but now it has tentacles sprouting from its back, ropy things with suckers that are strong enough to lift me from the bed and penetrate me whether I let them or not.
Daniel visits me every few days. There's no pattern, I never know when I go to bed if he will come in the night or not.
It usually starts with the creaking of hinges. That's what stirs me. I don't know where it comes from because I keep the hinges to all my doors oiled. But there it is. Then the covers shift, only barely, but I feel it, snakelike appendages sliding surreptitiously beneath my blanket to wrap around my ankles. And suddenly the sheets are thrown off and my legs dragged up into the air so high that I'm left resting on my shoulders. I feel tentacles around my waist, supporting me, around my wrists, holding me tight, and around my throat, strangling my screams. I see Daniels face between my legs and I'm so wet my pussy is practically dripping on to my face. I know whats coming next and I wouldn't miss it if you brought me the moon on a stick.
More tentacles surround me, some simply to support me in a position no human could, some to wrap around my tits, squeezing and kneading them and suckers tugging on my nipples. One appendage slides across my lips and I can't help myself, my mouth opens and my tongue savors the musky flavor, just a hint of saltiness and all delicious. Daniel lifts me clear of the bed, my knees spread, legs folded, arms behind me and I am truly, utterly at his mercy, completely helpless. I wouldn't have it any other way when finger-like tentacles pull my labia aside and expose my pussy.
I can't help but coo when something penetrates me, something thick and strong and flexible enough to push at my most sensitive spots. It was enough to make my toes curl and my eyes roll back into their sockets. Daniel settled into a rhythm fucking me, not very fast but determined, forceful while the end of its appendage writhed inside me in a way that nothing else could.
I felt my orgasm coming, building slowly, relentlessly. I felt it deep inside first, a fierce heat that couldn't be soothed, then it spread to my thighs, making my muscles twitch uncontrollably. I sucked on the thing in my mouth like it was pure, precious oxygen to a drowning woman.
Daniel was holding back, keeping me on the edge. I knew he had more to give and I wanted, needed it. When he let me have it it felt like liquid lightning throughout my body. It felt savage, my asshole stretching wider and wider, finally filling me to bursting. Within seconds I was convulsing in climax, my filthy screams muffled by the tentacle in my mouth. It felt like it lasted for days.
Finally, reluctantly, my orgasm subsided leaving me weak and gulping down air. Daniel withdrew itself from me slowly, tenderly and lay me back on the bed. I never remember it leaving, I'm fast asleep by then.
