Jeffrey sank to his knees, gasping and staring in mingled shock and horror at the two girls as Megan made her way over to Erin.
"How ya feeling girly?"
"Get away from me," Erin said, backing up.
"You're doing a bad job of escaping," Megan said.
She lunged forward and grabbed Erin, slapping her cum-soaked hand over the girl's mouth and nose. Erin struggled against her, but Megan was stronger, making sure to coat the girl's face in the fluid before stepping back.
"Something about boys drives us crazy. And, of course, we drive them crazy."
Erin wiped her face and looked down at the milky fluid glistening in her fingers. The smell, potent and alluring in equal measures, wafted up to her. Just having it on her skin was like having a current of electricity running through her.
"Someone's getting distracted," Megan giggled.
"I-no, whatever you're trying to pull, it won't work," Erin said.
Still, she kept sniffing her hand every few seconds. Here eyes were fixed on Jeffrey's semi-hard cock.
"I'm not trying to pull anything. You're gonna do all the work."
"Both of you need to leave. My girlfriend will be over and I-oh god what did I do."
"We're not going anywhere," Megan said.
She pounced on Jeffrey, pinning him to the ground. Her hand was on his cock before he had a chance to recover. Their lips met and Megan worked her magic.

Erin watched, frozen in place. On one hand, she was horrified. On the other hand, she could not tear her eyes away. Her vagina burned with need as she watched Megan dominate Jeffrey. Something stirred deep within her.
She took a step forward.
"Wow, Jeffery, you're hard already!" Megan cried.
"I really shouldn't do this," Jeffrey said. "You need to leave. Fuck, why do I keep giving in?"
"Because you want it, sweetheart!"
Erin moved closer. She wanted to fight back. To stop Megan. Unfortunately, her body had other plans. It screamed with need.
"Leave him alone," Erin said faintly.
"Or what?" Megan sneered.
"I'm going to stop you."
Erin stepped up to Megan and pushed her off of Jeffrey. The girl rolled away with a giggle, giving Erin a clear view of her classmate on the ground.
His cock was at full mast, it's head still glistening with cum. Erin could smell it's intoxicating aroma. It was almost as if she could sense energy throbbing through the member.
"Help Erin," Jeffrey panted. "Help me."
"Don't just stand there, help the boy," Megan said.
Within Erin, her insides felt giddy and hot, as if they were ready to jump out of her body. Goosebumps raised on the back of her neck.
"I want to help," Erin began. "Why do I feel like this. I feel like I'm losing control."
"Oh you are. You've been huffing in his scent for several minutes now and your changes are far enough along. Your urge to drain him is only getting stronger."
Erin growled and clenched her fists.
"I hate you," she said.
"What the fuck?" Jeffrey murmured. "This is freaking me out. You both need to leave."
"Quiet, Jeffrey," Megan said. "You can hate me Erin, but you know I'm right. I see where your eyes are at."
"You don't know me."
"Sure, but I know what you are."
"Get out!" Jeffrey cried.
"Then make us idiot," Megan snapped. "You still haven't gotten to your feet. The way you were sucking on my tits tells me you want us here."
Jeffrey blushed and turned away.
"Come on Erin," Megan continued. "Make a decision. If you want, I'll let you both get away from me. I won't do anything."
Erin turned to Jeffrey on the ground and extended a trembling hand. Her eyes were fixed on his dick. The harsh light of the dorm room made the residual cum on the head glitter. It smelled incredible.
Erin felt Jeffrey close his hand around her own, felt the warmth of his skin. She could smell his sweat and cum, his essence underneath it all.
She looked into the boy's eyes, feeling shivers run up her back. The room, now filled with their mingled scents, seemed to buzz with electricity.
The hard and hungry cock throbbed beneath Erin, begging to be touched. Erin wondered idly what it felt like. It seemed to be pouring energy into the air.
"I'm sorry," Erin whispered.
She let go of Jeffrey's hand and descended on his throbbing penis with mouth open and ready. Her soft lips encircled the head and tingled when they felt the warm flesh. The texture was everything Erin could imagine and more.
In one fell swoop, Erin took the entire member into her mouth, feeling the pulsing tip bump against the back of her throat. The taste was indescribable.
"No! What are you doing? Erin, I-ohhh!" Jeffrey moaned.
Megan burst into triumphant laughter.
"All that posturing and here you are eating his dick. I love it!"
Erin ignored her and began running her lips up and down Jeffrey's shaft, cupping his balls with her right hand.
"Stop! My girlfriend will-she's coming back. She-oh shit, it's so good!" Jeffrey babbled.
Megan sidled up behind Erin, hiked up the girl's skirt, and pulled down her panties, revealing her sopping, slime drenched pussy. Sticking her fingers between Erin's nether lips, the girl began to pleasure her new ward.
Erin threw her head back and cried out from the new stimulation, her pussy gushing slime and girl-cum. Jeffrey's dick, harder than ever and pulsing with unnatural desire, was gripped tightly in her fingers.
"What's the matter Erin? Weren't you going to stop me?"
"Fuck you!" Erin whimpered, feeling her pussy gush onto Megan's skilled fingers.
"I'd love it if you did, but right now, let's focus on more important things," Megan tittered.
She brought her tongue up to Erin's pussy and began to lick and kiss.
"Fuck!" Erin cried.
The girl held Jeffrey's cock tightly in her hand and brought her tongue to the tip. This had to stop soon. It was already going way too far as it was, but she just needed another taste of him.
"Oh God, don't stop," Jeffrey moaned. "I need this."
"I thought you had a girlfriend, Jeffrey," Megan crooned.
"It doesn't matter right now! I need this."
"Good!"
Meanwhile, Erin sucked Jeffrey's cock harder than ever, fondling his balls while forcing her crotch against Megan's assaulting fingers and tongue.
She could feel the power thrumming through the organ, ready to explode. No matter how hard she sucked, Erin could not satisfy herself and that energy she felt stayed locked away.
Megan pulled Erin's skirt to her knees and ran her fingers along the girl's dark, supple thighs.
Then she stood up and pulled Erin back by her hair. The girl screamed and glared at her.
"What's your problem? You wanted this, now let me have it!"
"No," Megan said. "This won't do. It's time for something more."
"More?"
"Come on, you know what I mean."
"No, I've already gone too far. I can't."
"What is your body telling you?"
The look on Erin's face told Megan everything. The girl cradled her head and fixed her eyes on Jeffrey's cock.
"I'm sorry Jeffrey, I shouldn't have done this to you," Erin said.
She was starting to cry again as her urges pushed her forward.
Meanwhile, Jeffery was consumed with lust, his former protestations burned away. He humped the air and begged for more pleasure.
"Come on, baby sister. It's impressive that you've resisted this far, but you're one of us now. Stop fighting and eat up."
Erin stood up and stepped out of her skirt. The cool air felt delightful on her burning cunt. Looking down, she saw Jeffrey's pleasure rod twitching in anticipation. She sank to the ground slowly, feeling the fever of lust descending with every second.
"I'm so sorry," Erin whimpered to Jeffrey. "I'm so-hungry."
She straddled the boy, carefully lowering her dripping pussy to his erect cock. The head pushed up against her lips, meeting a slight bit of resistance before entering her.

Erin felt the entire shaft slide deep within her. Something alien, stirring in her core, descended to meet the boy's prick. Suddenly, the wall between Erin and the energy she sensed in Jeffrey's cock disappeared and she could feel it flowing like hot water into her body.
"Oh God!" She screamed.
"That's the spirit, sis!" Megan shouted.
