You keep her in close quarters

You hold your sister tightly against you. The more she struggles, the more you hold her tight. The feeling of power is intoxicating.

You prolong this situation a bit longer pressing your body against hers. Finally she stops, abandoning herself to your iron grip.

“Sam…” she begs in a quiet voice.

“Yes Deb?” you ask playfully.

“Let me go, this in not funny.”

“Don’t you love me little sister? Do you feel uncomfortable?”

“Sam, I can’t breathe…”

“Liar, liar.” You whisper before striking.

Your fangs easily find their way through the thin skin of her neck. A fabulous sensation of bliss submerges you.

Deb, surprised, quivers under the ****, but as soon as you start sucking she loudly expresses her approval. Partially satiated you let her go.

She turns around. Her look is far far away. The pleasure and the blood loss make her gasp for air.

A thin string of blood runs down from the beautiful marks you left on her neck. Her blood pours between her discreet breasts. You lick your lips.

You hear the door of the suite opening.

“Deb? Where are you? The guys are waiting for us…”

It’s Caroline, her voice is thick, almost as thick as Deb’s blood. You can feel your sister starting to change. This could be fun. You grab your top and exit the room.

“ Where were you? We’ve been looking for you.”

“Guys?” you ask ignoring her question.

“Yes, two guys we met at the Celest’”.

“I wouldn’t mind a cock right now”.

Despite her **** clouded mind she stares at you wide eyed.

“A thick, juicy and long cock up my cunt, that’s exactly what the doctor prescribed,” you insist, “did you bring them here?”

Still under the shock of your filthy tongue whip, she nods.

“Well, what are you waiting for? Let them in…”

She stands still. Widening your eyes and showing the door with your head you express your irritation.

Complying she walks to the door. With the hand on the handle, she finally comes back to her senses. She turns around about to say something but you’re already on her. Your hand over her mouth, your fangs dig a large double trench into her cleavage. Her eyes are filled with tears of joy as you rapidly suck the life out of her. You toss her body behind a large couch.

“Sam? What is wrong with Caroline? She looks … tired.”

Deb is standing behind you. She must have been watching you and Caroline “make out”. She doesn’t seem to be bothered with what she just saw but she doesn’t seem to understand it either. Her transformation is well underway but her mind hasn’t adjusted yet.

“Don’t worry, she’ll be just fine in a minute,” you answer wiping the blood from your chin.”Why don’t you let the guys in?”

She walks to the door but you intercept her. You lick the drying blood from her chest and neck. The wound marks are almost closed.

“Much better,” you say looking at her pale body, “You can open the door now.”

The two men behind it fail to pass the prudish test and staring a bit below your sister’s chin they enter the room. The first to enter is tall, slender and bald with a delightful jaw. The large bulge starting to form on his shorts makes him all yours. The second one, a smaller version of the first one will do perfectly for your sister. They both wear UCLA sweatshirts

“Hi!”

Your first choice has a voice that doesn’t transpire intelligence.

“Where’s the other girl?”

The bluntness of the question does definitely disqualify him for the next Nobel Prize.

“Who? Caroline? She’s just changing”.

The muffled moaning sounds coming from behind the couch tend to confirm your affirmation. The two Neanderthals turn towards the couch.

“But do you really mind? I’m pretty sure that Deb and I can handle two big boys like you” you say showing your topless sister.

The eyes of the men are back on your sister’s chest. She looks less confused, actually the erected tip of her nipples tells you that the fog in her mind must be lifting. You close the gap between you and the pit of intelligence. You fingers run on top of his sweat shirt, you tap the famous university logo.

“You didn’t get in through academic achievement, did you?” you ask, a hint of mischief in the eye.

The only answer you get is a bovine stare of incomprehension. You shrug; after all you don’t want him for small talk. You run your fingers lower, over the bulge. The solid rod under the fabric is aching to come out. You must say that you are aching to have it in too.

You pull the man’s shorts on his knees. It’s rock solid and actually bigger than expected. Your already soaked undead vagina burps of anticipation at the sight of the instrument. It should fit just right in and if it doesn’t you’ll find a way. Still grinning you lift your skirt, pull out your thong and place your arms around his head.

“Come on baby, take me.” You growl.

The man’s hands on your hips help you thrust the monstrosity into your guts. You can feel it deep inside you, filling every inch of your hole. When it finally reaches the back of your pussy, you gasp and burry your head in his neck. Your fangs dig deeply into his artery.

He cries but you **** him to continue. Wrapping your legs around his ass you lock him inside you as deep as possible.

His blood down your throat and his semen up your cunt, you stand above his cadaver. Your sister is testing her new fangs on the second guy’s thigh. Her gaping ass is dripping with his seed. You purr at the delightful sight.

Caroline looking a bit lost emerges from behind the couch. She looks at you, at the man at your feet, at your sister, at the man under her incisors. She smiles, understands and joins Deb for her first meal.
Suddenly a terrible headache hits you.

“SISTER, YOU WILL COME TO THE BRIDGE, YOU WILL COME TO ME”
The voice in your head sounds like your own.
