The Urge takes over

Kelly turned to run as it lurched forward. It certainly wasn't Bobby. The thing she saw was darker skinned, and more importantly, missing its lower jaw entirely. A wheezing groan escaped what was left of its face as the wind lashed and whipped her. Its scent assaulted her. She thought she was going to throw up as she ran and the wind blew.

"Wha..." she thought. She felt her legs getting weak. "Shit! No!" she thought, her pussy aching suddenly. "No!" she whimpered in protest. Every stride she took sensitized her tender sex more and more. Soon, her thighs were shaking. Her run had slowed first to a jog, and then to a stumble. She was panting and quivering; her knees weak. "Why is this happening!?" she screamed into the night.

Kelly dropped to her knees. Her soaking wet pussy erupted in a sudden orgasm as she heard the groans behind her getting louder and louder. "Uhhgh! Ohh!" she moaned as she leaned back. She spread her naked legs and let the fluid drip from her spasming hole. She was gasping for breath when she felt it.

The cold hand pushed her forward by the back of the neck. Her nude, shapely ass jutted upward. Kelly held her breath as she felt its cold, dripping member press against her wet and wanton sex. "Oh fuck..." she thought as sparks exploded behind her tightly shut eyes.

"Uuuuggggggggggghhhhh" it moaned as its thick, leaking cock slid into her soaking hole. Kelly arched back, her whole body electrified. She gasped and involuntarily pulled at her hard, tender nipples as the disgusting thing wrapped its arms around her. She felt the wet meat of its face against her neck as cooed as its big cock started thundering into her spasming sex.

Kelly bucked and grinded against its thrusting member, her cunt tightly squeezing all of the leaking, lukewarm fluid from it. Its rough and ripped flesh slid over her smooth and soft skin as she started rapidly flicking her clit. "This is...disgus...OHH!!!" she thought as a massive wave ripped through her mind. She leaned forward and drove herself backward hard against its rapidly thrusting cock. She blushed as she felt her pussy convulse and cover it with her liquid sex as she drilled herself over and over.

Kelly pulled away and spun around, her knees wide open. The zombie descended on her. It was absolutely ghastly. No jaw, blind in one eye, and a sickly pale clay color. She grabbed its hips and pulled it deeper into her. Her legs wrapped around its waist and her eyes fluttered. The gorgeous blonde lay in the moonlit field being brutally fucked by an undead monstrousity as her brother lay asleep not 50 yards away.

Kelly's eyes fluttered as she vaguely heard her last moaning quiver escape her throat as the zombie filled her womb with its massive amount of cum. Over and over it filled her up, cum and her own juices oozing out of the 20 year old beauty as its thick cock hammered faster and deeper into her.

And just as suddenly as it came, it collapsed; still twitching inside of her.

She barely managed to crawl out from under its sudden'y dead, grunting weight. She scooped the cum from her body, and drank it, her body shivering like a hit from a narcotic ****. She looked up into the sky, and wondered what had just happened as she heard more and more moans coming from the treeline...
