Benedict Hall was close enough to the labs that Crystal decided to go there first. She wore an old sundress with no underwear or bra. She had a feeling she was going to want to be out of her clothes very quickly. Her 36 DDD tits pushed against the fabric, earning glances and glares from the people in the lab. She went to her station and started going over her work, but could barely concentrate. She looked at the clock, it was almost seven. She wondered what the girl, Isabella, had planned for the evening.
"So, the libido enhancer worked?" Professor Kawa asked.
She turned and looked at the wizened little man. He smiled at her.
"It's out of control," she said, sharing her hypothesis about it spreading through sex. He nodded his head as he listened. "We have to stop it."
"I'm afraid that's impossible," he said, folding his hands in front of him. "You've unleashed a most dangerous virus on the world. Look at what's become of you."
"What about a libido suppressor?"
"An anti-virus? How would you administer it?"
Her eyes suddenly went out of focus. She tried to think about it but her mind wandered.
"The physical change is interesting," he said, almost sounding disinterested. "Happens fast."
"Are you studying me?"
"Of course I am," he said. "How many partners have you had since your accident?"
She turned bright red then looked up at the clock. Her whole body shivered. She needed to go.
"You really can't help yourself?"
"I have to go."
She left him behind, rushing across the quad and to Benedict Hall. She took the elevator to the second floor and knocked on the door of room 207.
"Come in," Isabella called breathlessly. Crystal opened the door and walked in. Isabella was sprawled on the bed, her legs spread wide open and a naked boy on his knees between them going to town on her pussy. She was completely naked, her impressive 34D tits wobbling as she moved from the boy between her legs, her dark hair in two perfect braids. Between moans, Isabella said, "Get over here."
Crystal didn't even take her dress off, she straddled over Isabella's face, grinding her pussy onto her mouth. Isabella's tongue darted all over Crystal's sensitive pussy. Crystal giggled at first but then she started to moan at the pleasure radiating up her body.
"Who is this?" the boys asked.
"Shut up, Mike, and make me cum."
Mike said nothing, moving his head back between her legs. Crystal crawled off Isabella's face and moved down to suck on Mike's balls. He grunted in appreciation. Isabella cried out, clenching her thighs together as she came. Mike stayed still for a moment as Crystal tongued his balls. Finally she gave one strong suck and stood up.
"I want to fuck both of you," Crystal said, pulling the dildo out of her purse. She stepped out of her dress and put the dildo on. "You first big boy."
Mike stammered but before he knew it, his cock was sliding into Isabella's pussy. He fucked her hard and squealed a little when Crystal probed his ass with her lube covered fingers. He was so tight. This was going to be fun.
"Um, excuse me," Isabella said, "Don't stop fucking me."
