Experiment Barbie

Jim was waiting for the rest of the gang on the 3rd floor. He was hanging out in what looked like a small lab. There was cut up frogs and such on the tables. He shuddered and turned to the intercom. He turned it on leaned to the mic.

"Hey guys, I'm on the 3rd floor. Hurry with the t-blood would you?"

There was a locked door in the room. He was pretty much at a dead end. He explored all he could and examined all that might have been useful. He poked at the frogs until the door slammed open. Jim turned to the door dropping the stick.

Mark looked back at him. Jim then looked at who he carried in his arms. Cindy breathed heavily, with beads of sweat covering her face. He long pale legs glossed with her sweat over Mark's arms.

"What happened to her?" Jim asked concerned. He couldn't stop looking at her long half naked body.

"I'm not quite sure." he answered.

He put Cindy down and gently a chair under her before she fell. She plopped on to the wheeled desk chair, her legs spread, and her breast exposed within the open security jacket. Her head dropped forward, still breathing heavily.

Mark looked away from her and at Jim. He watched as Jim struggled to look at Mark, his eyes darting over to the naked blond.

"It might be a good idea if we get George to look at her." he said. "She doesn't look so good."

Jim nodded. "Yeah, she looks pretty sick." he agreed. "George and I split up. He said he's meet us here."

"That's not good." he said, shaking his head. "I'm going to go look him."

As Mark headed for the door, Cindy called out.

"Mark it's happening again!" she shouted, grabbing her left arm. "Oh my god!"

Mark was quit to act. He grabbed Cindy and bent her over the table. He unfasten his belt, letting his pants drop to the ground. He aimed his throbbing purple cock at Cindy's still moist and swollen cunt.

Jim's jaw dropped. He walked over to them, with a look of confusion on his face. "What's going on?"

Mark began to explain Cindy's condition, as he thrust his cock deep inside her. "Some bozo injected something in her that would kill her, unless she has an orgasm." he grunted.

Jim walked over to Cindy and dropped his pants as well. "Well I'm helping then."

Mark nodded. He turned Cindy around, after taking his cock out of her. Jim sat on the desk and began to jerk his cock. Mark spit in his hands and reached behind Cindy. He entered his fingers in her ass, getting it warmed up.

Cindy moaned as Mark teased her anus, adding more and more spit. She pressed herself against his body. He moved forward, gently guiding her to wards Jim. She brought her ass at his pelvic, as Jim aimed his cock as her anus. He slowly inserted his cock in her ass. She gasped as she felt her ass stretch over his long black cock. Mark aimed his cock and her pussy and inserted it. He to pound her pussy, as Jim tried to trust against his pounding.

Cindy shuddered with pleasure as she felt Jim's cock fill her ass and Mark pounding the back of her pussy. She then felt Jim reach for her breast. He massaged them, pinching her nipples occasionally. She held on to Mark, as she panted and moaned. His face tightened as he tried to hold himself from releasing his seed into her. She had to cum, wether it was Jim or Mark who made her do it.

Jim grabbed tight hold of Cindy's breast, as he pumped his penis in and hold of her ass. She was pulled on to him, as she squirmed and moaned. The sight to Jim forcing her down and her squirming was too much for Mark and he released in her cunt. He pulled out his half swollen member and stepped back.

"It's all up to you Jim." Mark grunted.

Jim lifted himself up as well as the moaning blond. He took his dick out of her and flipped her off of him. He stood up and belt her over the table. He placed a hand around her silver blond hair and one on her pale flat ass. His rock hard cock stood. He brought it to her ass and thrust inside once more.

The moment Cindy felt his long erection re-enter her she was off again, moaning and squirming. Jim held her in place, forcing her down on the table as he pounded her backside.

Mark watched, worried that he was being too rough on her. He felt something stir in his pants. He watched Jim's ass move back and forth as he fucked the poor blond. He spat in his hand and began to jerk his cock. He then advanced at Jim and grabbed him, pushing his cock in his virgin asshole. He cried out as Mark push him down on Cindy.

"What the fuck are you doing?" he screamed.

"Take it like a man, soldier." he grunted as he began to pull out.

Jim groaned as he felt his ass being pulled with his cock. Mark then thrust back inside, continuing the pattern. Jim's erection followed his lead, doing the same to Cindy, but slower.

Cindy looked up at Jim, his face tightening as Mark fucked him. She reached down at her swollen, cream pie and rubbed her clit. Jim looked down at her and moaned.

"Oh god, I'm coming." he groaned. He fell on Cindy, still rubbing herself. She felt Jim's seed in her ass and his cock soften up. Mark pulled Jim away and tossed him to the side.

"You weren't suppose to like that." Mark grunted. He brought his cock to Cindy's ass and continued where Jim had left off. His cock had more width compare to Jim's and she felt it. Her ass stretched as he began to pound it mercilessly. She felt her vaginal muscles swell and tighten as she came. She let out a long and loud moan as she did.

Mark noticed some juices running down his stomach. She had squirted all over him. Mark continued to pound her, even after she had came until he felt he was about to come again. He pulled out and emptied his seed on her stomach.

She laid on the table limp. Mark brought her up and placed his coat over her.

"Rest, okay?" he told her.

She nodded, her eyes already closed. Mark pulled his pants up and turned to Jim. He avoided his eyes and turned back to the microphone.

"Hurry up with the T-Blood, George. We have a patient for you here." he called out, his voice ringing through the school.

Mark headed for the door.

"Where are you going?" Jim called.

"I'm getting the t-blood." he said. "We need to get out of here."

He was gone through the door shortly after ending his sentence.
