You shiver in the large bedroom. You look at the empty fireplace, but there's no wood in it and you don't know how to light a fire anyway. You're a princess, not a servant. But princesses can get in more trouble- like the kind you're in now, kidnapped from your home by a monster.
Said monster comes in, and you shudder. It's a huge black dog with three heads and you gulp. The cerberus smiles with all of its mouths.
"My, my, my," the cerberus growls. You'd been forcefully given some potion by a servant once you were in the castle, so you can understand it. "How pretty you are."
"Let me go," you demand, even though your voice shakes.
"No, Y/N," the cerberus says casually. It starts to approach you and you backpedal. It bounds forward and gets behind you. You freeze. It starts to circle you. "Not until I've had my fun."
"The prince will rescue me," you announce.
"I doubt that. I killed him." This time, another head speaks.
You jerk. The cerberus laughs, a horrible grating sound. The cerberus leans forward and inhales near your skin and you flinch.
"I am Demetrius," the final head speaks. "You should know that."
"Why," you ask, shaking.
"Because you will scream my name." With that, the cerberus takes its massive paw and pushes you onto the bed. You try to get out of it, but a warning growl makes you freeze. The cerberus- Demetrius- climbs in after you and straddles you. It rips down the center of your body with one paw, and your clothes fall into useless halves. You try to cover yourself, but Demetrius pins your arms down. You squirm under its bulk and it laughs again. It lowers one of its heads and inhales near your neck. "You smell good," it growls.
"Unhand me!"
"No, pet. You will sit still like a good girl, or else you won't like what I do."
"What are you-"
Demetrius backs up and you try to bolt. But its outer heads take your arms in its jaws and you freeze, not wanting its teeth to puncture your skin. It lowers its middle head and licks your face. You try to get away from its tongue, move your head away, but Demetrius just keeps licking. It makes a rumbling sound, not a growl, deep in its chest. "I am going to let go, and you are going to stay still."
Demetrius releases you from its jaws and you try to get out of the bed again. Demetrius pins you down again, this time with a single paw. Demetrius growls and puts its head back, howling.
Servants come in with ropes and you thrash under Demetrius' grip. But your wrists are taken and tied to the posts. Demetrius lets you go and you squirm. The servants leave. Demetrius straddles you again. "Someday, you will listen."
"Let me go!"
Demetrius ignores you and licks your face again. This time, all of its heads are able to join in tasting your skin- the outer heads lick your arms. Demetrius walks backwards, licking down your body. You jerk when it starts to slobber on your breasts. The middle head goes back to your face and the outer ones work on both breasts. You try to squirm away, but it starts to feel good. The middle head shoves its tongue into your mouth and you can't even bite- the tongue is so huge that your teeth can't close.
"You taste good," the left head says. Then it goes back to licking. You squirm, trying to get away from the unwanted pleasure. You feel your pussy start to dampen and the middle head takes its tongue out of your throat and sniffs the air. "There you are," it says.
All three heads start to lick further down your body. It gets between your thighs and the outer heads lick your inner thighs. You bite your lip to prevent a moan from slipping out. The middle head looks up at you before delicately licking your slit. You jerk with a sob. It licks along your lips for a while, until you are tingling. You can't help your body's reaction- your legs spread. The middle head laughs as your face burns. "Look at you," it says. "Spreading your legs for me. You want to be my pretty little toy. You want to feel me inside you."
"No," you sob.
It shoves its tongue in. You scream. It starts to lick desperately and you, again, can't control yourself. You start to fuck yourself on its tongue. The left head laughs because the middle is preoccupied. "Yeah, that's it, Y/N."
You can feel Demetrius' drool soaking you and tell yourself that's why you're dripping. But your own wetness is helping. You feel an orgasm building and sob. Then Demetrius pulls back, its tongues disappearing. You look down and whimper. Demetrius just looks at you and grins.
"Ask nicely."
