Andrea had only been working at The Research Institution for Latent Emotions for a couple of weeks, so was slightly surprised when she got a text message from the Head of Research. The text arrived Saturday evening whilst she was out at dinner with some girlfriends and demanded her presence at the institute first thing the following morning.

At first Andrea was worried that she'd done something wrong and was being called in to be rebuked or even dismissed, not that she could recall anything she'd done that might reflect badly upon her. And it was also very odd that she was being told to come in on a Sunday when everything was usually closed and locked up. The only thing she could think of was that something unexpected had happened at the institute which required her assistance to sort out.

"Problem?" one of her friends asked.

"I'm not sure" Andrea responded.

Andrea tried to put the matter out her mind for the night and enjoy herself, but it wasn't to be. She wondered if there had perhaps been an accident in one of the labs or an experiment had gone amok. Maybe there had been a break-in at the institute or it had been the victim of a cyber-attack. She became more and more intrigued about what she might discover when she got there.

The evening passed in a bit of a blur for Andrea. When it came time to say goodbye she realised she'd spent the entire evening worrying about tomorrow rather than joining in with her friends.

"Sorry if I've been a little distracted tonight" she apologised.

"Maybe you can tell us all about it when we next meet?" one of her friends suggested.

"It's a promise!" Andrea declared.

The following morning Andrea was up early. She had a quick shower and changed into a smart grey skirt suit before wolfing down a bowl of cereal and then heading out. The institute was a good ten-mile drive away but as it was Sunday morning there was virtually no traffic and Andrea was soon waving her ID card at the security guard at the front entrance. She parked up and went into the building.

Usually Andrea would take the lift up to her lab on the third floor but as she'd been told to report to the head of research whose office was located on the first floor she took the stairs instead. She saw that the light was in the office, so knocked on the door and waited for a response.

"Come in" a voice called out.

Andrea stepped into the office to discover two women standing inside. The first was her frequent lab partner Sally whilst the second, a smartly dressed woman in her early to mid-forties, wearing glasses and with her hair tied back in a bun, was unknown to her. The woman turned to Andrea and beckoned her forward.

"I'm Dr Thompson the head of research" the woman said as she held out her hand to Andrea.

Andrea shuck her hand and waited politely for Dr Thompson to explain why the three of them were here at the weekend.

"What I'm about to tell you must be kept strictly confidential" she stated.

Dr Thompson went on to explain that yesterday they'd had an unfortunate occurrence at the afternoon tea party they were hosting in aid of the mayor's favourite charity. They suspected that an accidental leak of one of their experimental serums had occurred and caused the attendees to act in an unexpected manner. They wanted Andrea and Sally to undertake a series of tests to confirm that it was the serum that was responsible for the incident.

She also stated that as they were working on a Sunday, they would receive double pay and the institute would pay for any dry cleaning. Andrea was a little puzzled by the offer of dry cleaning, but the extra pay was certainly welcome, and she had no hesitation in agreeing to the help even if she did plan on ignoring the confidentially and telling her friends all about it.

Andrea and Sally made their way to the research lab which had been allocated for the testing. Apparently, all the materials needed had already been transferred into there and full instructions had been printed out and placed in the work bench. As they walked over they chatted about the weather, travel and of course the latest "must watch" TV programme.

It wasn't long before they arrived at the lab. Andrea passed her ID card near the sensor and waited to hear the door unlock. She then held the door open to allow her colleague to enter first and followed her in shortly afterwards. Both were somewhat surprised by what the found in the lab, the long work bench was covered in various sweet desserts. There was also a white lab coat and clipboard at the far end of the bench.

Andrea went over to examine the desserts whilst Sally checked out the paperwork attached to the clipboard. Andrea couldn't take her eyes off the huge variety of pies, cakes, flans and tarts present so didn't see her colleague start to grin as she read through the tests or put on the lab coat. In fact, she only paid attention to Sally when she picked up a pie from the table and walked over towards her.

"What are you doing with that?" Andrea asked.

Rather than respond verbally, Sally smiled briefly at her before thrusting the pie into Andrea's face. Andrea was shocked by her colleague's action and couldn't quite believe what had just happened. She reached up and wiped the pie cream from out of her eyes before glared at her colleague.

"So fancy lezzing out with me yet?" Sally asked.

"What the hell, Sally!?" Andrea exclaimed.

Sally handed Andrea the clipboard with the instructions on them. A quick glance over them revealed that the tests called upon one person to repeatedly pie another in a variety of different styles to determine if they got unduly turned. Andrea looked up in disbelief at Sally, only to see that her colleague had grabbed another pie from the table and was waiting patiently to continue the tests.

"Now wait a second" Andrea said.

But Sally didn't wait and thrust the second pie at Andrea. Luckily for Andrea she was better prepared this time and managed to duck out of the way as the pie went sailing past and splattered against the wall with a definite squelch sound. Andrea sighed in relief as she looked at the mess on the wall and not on her. Unfortunately, that meant she had her back to Sally as she picked up another pie.

Andrea only became aware of the pie when Sally reached around and smeared it a cross Andrea's face. The sloppy filling ran down her face and over her once pristine blouse. Andrea shook her head in resignation, especially as she saw Sally picking up a pair of tarts from the bench.

"I can see why they offered dry cleaning now" Andrea muttered.

Still following the instructions on the clipboard, Sally stepped forward and sandwiched Andrea's head between the desserts. She then took up a flan and deposited it upside down on top of Andrea's head.

"Do you think they'll throw in a visit to the hair salon as well?" Andrea wondered aloud.

Her colleague ignored the question and went over to the other side of the lab to grab a chair. For a moment Andrea thought her ordeal might be over but then she noticed Sally picking up a trifle and placing it on the chair. It was obvious what Sally intended but Andrea was reluctant to comply as she was wearing one of her favourite skirts.

Sally solved this by stripping Andrea of her skirt to reveal her white panties before pushing her down onto the chair. Andrea moaned in disgust as her cotton clad bottom landed in the waiting dessert and the cream, cold custard and jelly began to soak into her panties. However, Andrea had to admit to herself that the sensation wasn't entirely unpleasant.

"You'll need to remove your blouse for this next test" Sally declared.

Once again it didn't take a genius to know where the next pies would soon be ending up. Andrea removed her blouse as Sally grabbed another couple of pies. Then with Andrea sitting there in just her underwear, Sally thrust the pies against Andrea's chest and proceeded to smear them all over her bra.

Andrea found she was now starting to enjoy the experience and in truth was getting more than a little turned on by it. She knew it must be the effects of the serum, and that she was unable to resist it, and in all likelihood would soon transform into a rampart lesbian nymphomania. Sally also noticed the change in her colleague, especially when she removed Andrea's bra to expose her erect nipples.

"It appears these tests tend to confirm Dr Thompson's hypothesis" Sally stated, "but I think we need a little more data."

Then with Andrea looking on expectantly, Sally picked up a large icing covered cake and was about to deposit it on her colleague's chest when Andrea leaped up and forced Sally to smash the cake into her own face. As Sally staggered back, temporarily blinded by the cake, Andrea stood up and grabbing hold of her, forced her over towards the workbench and the remaining desserts.

Andrea pushed Sally's head down into a cream flan whilst stripping her of her white coat. She then pulled up the back of Sally's dress up and slapped a tart against her bottom. Sally managed to straighten herself up and turned to face Andrea only to be the recipient of a pair of pies to either side of her head. As Sally attempted to clear her face of the pie filling, Andrea stripped her of her dress to reveal that she wasn't wearing a bra and had on only a pair of pink thong panties.

"Naughty girl" Andrea said admiringly.

Sally attempted to cover up her breasts, but Andrea objected. She pulled Sally's hands away from her chest and scoping up a handful of trifle rubbed the dessert over her breasts. Sally gave up resisting and let Andrea continue her wonderfully massage. Sally reached out to embrace Andrea and the pair of them looked in to each other's lust filled eyes. Andrea leaned forward and place her lips upon Sally's.

Suddenly the door burst open and Dr Thompson entered pushing a trolley laden with more desserts. Looking up she suddenly noticed the state of the two women in the lab.

"What on earth's happening here?" Dr Thompson demanded.

"Proving your suspicions about the serum are correct" Sally responded matter-of-factly.

"But those are just the control pies," Dr Thompson stated before indicating towards the trolley "these are the ones sprayed with the serum."

Andrea and Sally looked at one another in shock. Sally became self-conscious and tried to say something, but her mind drew a blank. Andrea however wasn't embarrassed. In fact, if anything she was frustrated that they'd been interrupted, and their moment ruined. If only there was a way to persuade Dr Thompson to leave or better yet to join in. Suddenly Andrea knew what to do.

"Well in that case we'll need a fresh test subject" Andrea said.

And with that Andrea quickly grabbed a cream pie from the trolley and thrust it into Dr Thompson's bespectacled face. She followed that up with another pie to the face before sandwiching Dr Thompson's head between a couple of fruit tarts. Sally then joined in by dumping a flan on top of Dr Thompson's head before the pair of them stripped the Head of Research of her clothing and covered her naked body with all bar the final two pies.

Before the two colleagues could complete their "tests" Dr Thompson held up a hand to stop them. Reaching up she removed her glasses and untied her hair, allowing it to spill out across her shoulders. Tnen looking over at her two assailants she started to grin wildly; it seemed that either the pies or the serum had had their effect upon the good doctor.

"Time to lose those panties ladies" she instructed.

Andrea and Sally glanced at one another and smiled as they did as instructed. Once completely naked the pair waited impatiently as Dr Thompson picked up the remaining couple of pies off the trolley and approached them.

"So, what was the problem at work?" her friend asked.

Andrea thought back to the previous Sunday and her adventure at work. It had been fatally amazing and something she was keen to repeat as soon as possible. Of course, it wasn't something you could easily describe even to your best friends; it was something you really needed to experience for yourself.

"Oh, just an accident in one of the labs" Andrea said "however, I did earn us all some tickets for a special event they're holding."

The End . . ?
