Part VI

4x10 The Alien Parasite Hypothesis

Amy: Let's look at this logically. I have a stomach, I get hungry. I have genitals, I have the potential for sexual arousal.

Sheldon: A cross we all must bear.


Amy: Is it possible that your concern for me at this moment is motivated by nothing more than simple jealousy?

Sheldon: I hadn't considered that. Give me a moment. All right, I've considered it.

Amy: And?

Sheldon: I reject it.

Amy: You reject it because you don't feel jealousy, or because you are suppressing jealousy?


Penny: I'm suggesting there might be something you could do about Amy's urges?

Sheldon: It's illegal to spay a human being.

Penny: Yeah. That's not what I had in mind.

Sheldon: Oh. Oh! You mean something I could do.


After folding his freshly laundered and dried t-shirts, Sheldon still couldn't get his mind to stop thinking about what happened with Amy that afternoon.

Him, jealous? He harrumphed. The thought alone was preposterous.

Yet he couldn't help but be at least a bit insulted that Amy had such a strong bodily response to Penny's buffoon of an ex, and not to him (to his knowledge, that is). He was a Homo Novus after all. And he was Amy's intellectual equal. It made all the sense in the world that this whole case of her baser urges acting up with another male caused a bit of anger with him.

That didn't mean she had the right to call him out like she did.

His talk with Penny had only worsened this nagging feeling in the back of his brain. Doing something about Amy's urges. He really didn't want to. But what choice did he have? He wasn't going to stand by and look on how his one true intellectual equal became a slave to whatever her hind brain ordered her to.

Sheldon busied himself going through the book Leonard and Penny had given him once. He had already skimmed through it once before, but he had been so disturbed by the things he read, that he had stopped. He was a quick reader however, and was soon able to finish the parts he deemed necessary.

He looked around the apartment. Leonard still hadn't returned home. He needed him. If not for the ride over to Amy's, at least for some advice.

Who would have ever thought the day would come where he would ask Leonard for advice, and not the other way around? He laughed at the silliness of the thought.

It was already well past eight, and his bedtime was approaching rapidly.

Sighing deeply, he pulled his phone out of his pocket and hit speed-dial one.

"Hey, Sheldon," the disembodied voice of his roommate sounded through the ear piece. There was a strange echo present.

"Leonard," Sheldon started, ready to begin his monologue, "I'm in need of your assistance, earlier today - -"

He halted. The noises on Leonard's side of the line bothered him. "Where are you?"

"The gymnasium," Leonard said, exasperatedly. "Koothrappali and Wolowitz are having a wrestling match. Hold on, I'll go out in the hallway. It's not as if anything is actually happening after all."

Sheldon waited for a beat, and decided to just go ahead and ask what he needed to know. With Leonard still at the university, it would appear he would have to take the bus over to Amy's instead of a car-ride over there. That also meant getting his bus pants out. He looked up to the skies, the things he did for friendship. Or maybe Penny could drive him. She had appeared to be supportive of his plan.

Sheldon cleared his throat. "To your experience, what have you found to be the most effective way to bring a woman to orgasm?" he asked, his voice ringing out clear in the otherwise empty apartment.

There was silence on the other end of the line.

"I'm sorry," Leonard said. "What did you just say?"

Sheldon rolled his eyes. "If you were to want to pleasure a woman sexually, what has proven to be the most effective way to do so?" he spoke slowly and clearly. There must have been something wrong with the connection, Sheldon thought he had been pretty clear with his first statement as well.

Leonard was silent again. "What prompted this, Sheldon?"

Sheldon could hear the suggestive tone in his voice.

"That's neither here nor there," Sheldon said gruffly. If he wanted to take care of this today, he didn't have the time to explain the entire situation to Leonard. He wouldn't understand anyway.

"I'm just going to assume this has to do with your new friend who is a girl, but not your girlfriend," Leonard continued.

Sheldon said nothing in return, neither confirming nor denying what was going on.

"Well," Leonard said, and he sounded sort of embarrassed as he continued, "the first thing you should know is that all women are different and not everyone likes the same things…. Most of them like - - You know what, why don't you read that book we got you?"

Sheldon sighed. "I already did. So you can skip over the bases of erogenous zones and proper lubrication before intercourse." Sheldon shuddered. He was hoping to avoid a lot tonight, and intercourse was surely one of them.

Leonard coughed awkwardly. "Right."

Sheldon was losing his patience. "So, to your experience, what is the quickest and most effective way to bring a woman to orgasm?" he really had no time for this. He looked at his watch. It was already approaching eight thirty.

"As I said, everyone is different," Leonard said, sensing Sheldon's impatience, "usually ehm… fingering… is enough to get a woman there."

He said the word like it was a dirty secret. Sheldon rolled his eyes at the childishness of his behaviour.

"So manual stimulation?" he clarified. He was relieved. Of all the ways to do this, manual stimulation seemed the lesser of a lot of evils.

Leonard kept making awkward and embarrassed sounds. "Well, yes," he mumbled. "But if you really want to be sure a woman comes, there is no going wrong with eh.. oral stimulation."

Sheldon blanched. Drat.

It was his turn to cough. "You mean cunnilingus?"

"Yes."

Sheldon thought for a second. It was Amy's usual shower time right now. Perhaps that wouldn't be so bad if she had taken a shower beforehand?

"Alright," he said, ready to end the call.

"Or, you know… Both oral and penetrative stimulation at the same time works great too," Leonard said.

Sheldon blinked in confusion. "How does that work? You can't possibly be flexible enough to both penetrate a woman and orally stimulate her simultaneously," he huffed.

Leonard laughed. "Penetration with something else than the penis, Sheldon," he said, and Sheldon had the feeling he was being laughed at.

"I was just testing you," he rebutted, blushing with suppressed embarrassment. He had only just realised what Leonard meant.

"Sure, buddy," Leonard said.

What followed was an awkward silence.

"I should go," Sheldon said. His talk with Leonard hadn't really helped him with his problems. As a matter of fact, it only caused more questions to form in his mind.

"Say hi to Amy for me," Leonard chuckled and hung up.


Sheldon had never been to Amy's apartment, but she had mentioned where she lived to him once. His eidetic memory had stored it in the file cabinet labelled "Amy" in his mind. He took the elevator up the third floor and couldn't help but smile when he stood in front of her door. How fitting that she would live on number 314. Although 73 was the best number, pi was limitless and would always hold a special place in his heart.

He knocked on her door three times, calling out her name between each set.

Amy opened the door with a look of surprise on her face. Her hair was slightly damp and she was wearing a high-closed robe. Sheldon breathed out a sigh of relief; she had just taken her night-time shower. That would make this whole ordeal a little easier at least.

"Sheldon," Amy stated, obviously surprised, "what are you doing here?"

Sheldon looked down. He couldn't just say that out here in the hallway now, could he?

"Can I come in?" he asked instead. Amy raised her eyebrows at him, but moved aside nonetheless.

Sheldon looked around her apartment. It was nicely decorated. Feminine. But with some scientific touches he appreciated; a phrenology head, the three wise monkeys and books. Lots of them. It helped him feel more at ease.

"This is a surprise," Amy said. "I didn't expect to see you after you left in such a huff this afternoon."

Sheldon inhaled sharply. If this was going to her attitude tonight, he wouldn't go through with it. "That is actually the reason I'm here," he said.

Amy blinked at him. "You could have just called me to apologize, Sheldon. Coming over wasn't really necessary."

Sheldon looked at her blankly.

"I didn't come over to apologize," he stated. Surely, Amy would understand what he meant.

"Okay?" she said, looking at him questioningly. Apparently not.

Sheldon exhaled shakily. "You said something this afternoon that got me thinking," he said, trying to sound confident but aloof, "it bothers me when we're not able to converse at our usual intellectual standard. This sudden biological urge that has come over you has changed that. I know it is not something you can control, therefore I am here to help."

"To help?" Amy repeated, uncomprehendingly. The tips of her ear were red though.

Sheldon nodded gravely. "I'll just wash my hands before we get started," he said, "the germs on the bus can be quite persistent." He stalked over to her kitchen and turned on the faucet, lathering up his hands.

"Get started with what exactly?" Amy asked. There was a stutter in her voice.

Sheldon cut off the water and grabbed a nearby towel to dry his hands. He could feel a blush heat up his neck. Did she actually want him to say it?

"The solution to your state of heightened sexual arousal," Sheldon started and Amy inhaled sharply, "is obviously a release – a climax if you will – after which you will be capable of returning to your normal intellectual self."

Amy looked affronted. "Are you suggesting I'm less of an intellectual when aroused?"

Sheldon stammered. This wasn't going well. "That's not what I meant," he corrected himself quickly, "what I meant to say is that, with your symptoms out of the way, we're able to put this thing behind us and continue as we started: discussing topics of interest, without either party being a slave to their baser urges."

Amy was blushing. "And how do you propose to get rid of my symptoms?" She was calling him out.

"Your bedroom is that way, I take it?" Sheldon asked, indicating to an open door behind her.

"Y-yes," Amy replied after a beat.

Sheldon nodded gravely and walked briskly towards the open door. He didn't hear her following him, and he turned around in the doorway. "Are you coming?"

"Apparently I will be," Amy mumbled quietly.

"Excuse me?" Sheldon asked, wondering if he heard her correctly.

Amy looked up, her face fully red by now.

"I have been assuming this is what you wanted," Sheldon said, suddenly aware of the fact that he hadn't asked her for consent. "I know I don't have the physiological characteristics that Zack has, but I am a member of the opposite sex. I would think that would work as a stimulant to you?"

Amy gaped at him. "I don't know," she said, fiddling with her hands.

"Right," Sheldon said, confused by her reactions. Perhaps he had underestimated the importance of the visual stimulus Zack had provided. He obviously didn't have the physiological attributes that she preferred. "Shall I leave then?"

Amy blinked at him. "I don't know," she said again. "I am perfectly capable of providing myself with sexual gratification, you know. But I must admit that you've peaked my curiosity with your offer."

Sheldon's eyes widened. His mind was suddenly filled with an image of Amy Farrah Fowler, in her bed, with her right hand under the blankets, moving rapidly between her legs, her hair a mess and her head thrown back in ecstasy, gasping for breath.

He swallowed thickly. "So?" he asked.

Amy bit her lip. "I see no harm in trying," she said. Sheldon suddenly saw a lot of harm in trying though; the words she said had caused his body to respond in a way he hadn't expected.

"Alright," he said anyway, holding the door open for her. "Let's get this over with then. It's getting closer to my bedtime with this stalling behaviour of yours."

Amy looked at him hesitantly, but walked in anyway. She halted at the side of her bed and she looked at him questioningly. "Shall I just lay down or something?"

Sheldon felt a slight twinge of panic. Maybe this wasn't the best idea after all. Why was he suddenly nervous? That wasn't like him at all. He nodded at Amy.

Her hands moved to the sash holding her robe closed, her fingers untying the knot at the front.

"What are you doing?" Sheldon exclaimed, shocked.

Amy looked at him. "Shouldn't I be naked for this?" she asked.

"Well," Sheldon stammered, "technically I only need access to your lower half for this." The thought of seeing everything of her made him incredibly nervous somehow.

Amy blushed. "You're right," she said, "I can just open my robe in the front."

Sheldon nodded. He watched Amy climb on top of her bed and the mattress seemed to move with her. His eyes must have been playing a trick on him. Amy had scooted to the middle of the bed and looked back up at him. "Shouldn't you at least get your pants off?"

Sheldon blushed. "You misunderstood me, Amy," he said, looking anywhere but her face, "I won't be undressing for this. I've read up on the subject and there are much more efficient ways for women to reach a climax besides intercourse. I was planning to do try those first."

"Oh," Amy uttered. And for a second Sheldon was almost sure she looked disappointed.

He blinked at her. "If at any time you feel uncomfortable, tell me immediately, alright?" he asked, looking in her eyes. Amy bit her lower lip and nodded at him.

He took a seat on her side, and the mattress dipped beneath him and moved in some sort of wave to the side and back. He yelped in shock.

"It's a waterbed," Amy explained unnecessarily.

"It's like being on a boat," Sheldon said in disdain, regretting this more and more. How could she sleep on this?

Amy shrugged. "I guess," she said.

Sheldon sighed. One more reason to get this over with as soon as possible. The list was getting longer and longer. Another thing had just joined the list as well; this close to Amy he could smell either some body wash or lotion or something else fragrant. The smell confused him.

"I'll just, ehm.. get started then," Sheldon said, and looked at his watch subtly. He never went to bed later than 10 PM on a Friday night, and it was already a quarter to now. His entire weekend would be disrupted because of this.

He grasped Amy's knee carefully. Her skin felt smooth and warm. This was alright, he thought. He could handle this. Slowly, he moved his hand upwards on her thigh, caressing her softly with each stroke upwards.

He looked back up at Amy, watching her face carefully. Her breathing had increased, and she was watching him intently. Sheldon raised his eyebrows slightly, silently asking her if this was okay.

Amy moved her legs apart in response. Sheldon held her gaze as she did so.

His hand was at the top of her leg now. Still looking in her eyes, his hand grazed her hip and moved higher under her robe, caressing her across her stomach. She trembled underneath his palm.

He repositioned himself slightly on the bed, and it caused another wave of water to move underneath the two of them. He wasn't ever going to get used to the bed moving under him like this. He grabbed hold of her robe with his other hand and moved it open, flipping the flaps open on both sides.

Sheldon was able to look at her now.

His eyes moved over her, from the patch of neatly trimmed hair starting inches under her belly button to the darker pink part of her between her legs. It glistened with wetness.

He glanced up at Amy again. She was blushing like he had never seen her blush before. Was she embarrassed? He couldn't understand why; the book had depicted multiple drawings of what female genitalia could look like, and hers looked just like one of the drawings in the book.

Sheldon breathed out deeply, and moved his right hand from her tummy down between her legs. The moment he came in contact with her labia, he felt something akin to a shock go through him. Amy gasped. She was slippery and soft and almost pulsing beneath his fingers. Although he had read about it, he hadn't expected this.

Was she aroused already? Or was this normal?

He had expected her not be this wet, but the more he moved his fingers over her, the more wetness he encountered. "Amy…" he murmured.

"Yes?" she answered, breathless. The way she spoke caused tingles to move through his body.

"Are you aroused, or is this wetness normal?" he asked, pretty sure he knew the answer but needing to know for sure.

Amy turned even redder. "I'm aroused," she whispered.

"This fast?" Sheldon asked, flummoxed. When he had read about arousal in females, the book – and Leonard and Wolowitz over the years as well – had been insistent about preparing a woman thoroughly through an intricate series of touches and kisses and other things to get her ready for any sexual act.

"I barely touched you," he added, confused still.

Amy huffed and had her eyes closed tightly. "I assume the anticipation worked well enough," she mumbled.

Sheldon nodded. He wasn't going to complain. He moved his fingers over her, over her folds, the entrance of her vagina and over the hardened nub at the front of her body. Amy gasped softly when he touched her there. Sheldon figured that was the spot he needed to focus on and to get the desired results in the shortest amount of time.

He caressed her there again and Amy sighed softly again. Warmth spread through his body in response. Sheldon blinked rapidly, trying to focus on the task in front of him instead of the strange things happening to him suddenly.

He moved around on the bed awkwardly, trying to find an angle to touch her there without straining his wrist too much – he couldn't risk getting carpal tunnel syndrome, he needed his right hand to play Halo with, after all. It was difficult, and the sounds coming from Amy's throat weren't the gasps of pleasure he had expected, but grunts of discomfort instead.

He had finally found a position with which he could stroke her over her clit without the stings of pain in his wrist or cramps in his fingers, but Amy's breathing had evened out and she was looking at him through half-opened eyes with a furrowed brow.

He tried to create some sort of rhythm in his strokes, but his fingers slipped away every time and Amy was squirming under him, but not in a way that looked like she was enjoying this.

"Sheldon," Amy said awkwardly, "this isn't really working. Maybe we should stop."

It wasn't his fault, he thought angrily. There was too much wetness there for him to create some sort of friction, his fingers kept slipping.

Sheldon huffed. "You're not giving me any instructions whatsoever," he said petulantly, "I don't know when I'm doing this correctly and when I'm not."

Amy looked away. Sheldon had sat back a bit, and he was looking at his right hand in the awkward silence around them. His fingers were shiny.

"Reaching orgasm is all about being able to surrender mentally as well," Amy spoke softly, like she was trying to spare his feelings for failing at this. "I think you just caught me off guard with this whole thing. Maybe some other time?"

Sheldon shrugged. He was pissed off to be honest. Here he was, feeling like he failed – and Sheldon Lee Cooper was never unsuccessful – just because Amy couldn't get her mind ready to orgasm. Or whatever lie she was trying to feed him.

"I don't think that's it, Amy," Sheldon said, calling her out this time. "You just haven't given me enough time to try everything."

Amy blinked at him. "What do you mean?"

Sheldon looked at his right hand again. He lifted it up towards his mouth, and the scent coming from his fingers made his eyebrows rise. He had never smelled anything quite like it. His tongue darted out on its own accord, and he licked across his still glistening fingers.

In his peripheral vision he could see Amy's jaw drop open in shock, but Sheldon was more focussed on the lingering taste on his fingers. It wasn't at all unpleasant. He blinked rapidly. He had not expected that.

He looked back to Amy. She gaped at him still, her eyes wide.

"Lay back," Sheldon commanded softly, pushing her legs open further and climbing on top of the covers on his knees now.

"Sheldon," Amy said, "I don't think I can tonight. I guess I'm not in the right mood."

Sheldon raised his eyebrows. "Only this afternoon you were telling me about your throbbing ears and genitalia," he said, "this heightened state of arousal is probably related to your menstrual cycle. If my guesses are correct, you're ovulating right now."

Amy blinked at him. "So?" she said, and she sounded kind of irritated.

"So, you'll be in the right mood again in no-time," Sheldon replied. Amy was silent. Sheldon figured he really couldn't give up now. He had already tried more than he would have ever thought, and he still hadn't gotten the result he wanted. That wouldn't do.

Sheldon gave her a look. "Will you let me try once more?" he asked.

Amy still looked sceptical, but nodded slightly anyway. "Alright," she muttered.

Sheldon nodded back. He looked her over once more. She was laying on the bed, the blush still present on her cheeks. Her robe was closed, and she had closed her legs again.

The chapters on foreplay flashed rapidly through his head. He was somewhat glad he hadn't spent all this time reading up for nothing. He clumsily moved forward, resting his hands beside her shoulders. He was hovering above her. Their sides were touching somewhat, and Sheldon realised this was the most their bodies had ever been in contact.

Amy blinked up at him.

Sheldon looked back at her. He guessed there was a certain attractiveness about her that he never really noticed or thought about. There were little golden flecks in her otherwise green eyes, and her lips looked plump and inviting.

He swallowed hard.

"I'm going to kiss you now," he muttered.

Amy inhaled sharply through her mouth. Sheldon watched her pupils dilate.

"O-okay," she whispered.

Sheldon bent forward and he brushed his lips across hers timidly. Oh, this was different. Amy puckered her lips in response, and within the blink of an eye their lips were moving against each other in shy kisses, and soft brushes of lips.

Sheldon breathed out slowly, and Amy moaned softly. While he knew that he was already getting her aroused again – and there really was no need to continue this much longer – he couldn't seem to stop himself from kissing her for another couple of minutes.

He leaned on his left arm, and with his right he moved his hand over the lapels of her robe. He pushed the fabric aside and touched the bare skin underneath. Amy inhaled sharply and made a soft keening noise which caused his blood to flow lower. Sheldon quickly diverted his thoughts to what he was doing.

He moved his hand until he enveloped her breast. Amy pulled back from his head to gasp loudly. Sheldon was breathing rather harshly himself, he realised. He made a sort-of kneading motion with his hand apprehensively, brushing his thumb over her nipple in the process.

The effect was instantaneous. Amy mewled and arched her back, moving her breast more firmly in his palm. Sheldon repeated the motion, feeling her nipple harden under his thumb. He stared at her. Her face was flushed and her mouth was opened slightly, panting softly.

Fascinating.

He was suddenly overcome with the desire to kiss her again, so he did. He moved his head back towards hers and closed his mouth over hers just as he pinched her nipple between his thumb and his index finger. Amy gasped into his mouth and Sheldon felt her tremble under him.

Sheldon moved his hand to her other breast and this time went for the nipple right away. By the time he had manipulated it to a hard peak with his fingers, Amy was a moaning mess under him.

He pulled back from her and regarded her. Should he ask her if she was 'back in the mood again'? The question seemed redundant. He bent down to her neck now, pressing kisses under her ear and steadily moving downwards.

"Hoo!" Amy exclaimed, and Sheldon grinned against her skin.

He moved lower still, dropping kisses across her sternum and moving her robe open fully now to clear his path downwards. He sat back up and pushed Amy's legs back open once again, this time moving his body between them quickly.

He kissed her between her breasts again, and looked up to see her reaction. Amy was looking at him apprehensively. Well, Sheldon thought, apprehension was to be expected. He didn't really know what to expect himself.

The annoying bed moved underneath him again as he moved down. He halted for a second when he moved below her belly button. He looked up at Amy once again. She was looking at him wide-eyed, but made no move to stop him.

Sheldon exhaled slowly, mentally preparing himself for what he was about to do.

The scent of her was almost overpowering from this close, and he wondered if she tasted the same directly from the source as she had from his fingers. Bending forward, he parted his lips and placed an open-mouthed kiss on her.

He listened carefully to Amy's change in breathing, while he moved his lips over her. His tongue darted out of his lips, and brushed across her slick folds, and he heard Amy gasp. He had located her clit easily, and focussed his attention there. He tugged on it softly with his lips, his tongue moving rapidly over her.

Amy was moaning faintly, and she was squirming again. This time not out of discomfort, Sheldon figured. Moving lower, he lapped at her. He couldn't get enough of the taste of her. Once he had gotten used to the strange, musky taste, he couldn't help but savour it. His tongue was darting out against her entrance, carefully pushing inside her. Amy whimpered.

He suddenly understood what Leonard had been talking about. There really was no going wrong with oral.

He moved back up, ready to give his undivided attention to her clit again, and the bed helped push upwards with the waves it made with every movement. Wrapping his lips around her, he sucked softly and Amy moaned loudly.

"Sheldon…" she whimpered, and Sheldon felt his dick harden in response. He tried to close his mind of from whatever this was doing to him. His hips moved against the mattress though, creating some sort of friction against his hardening member in his pants. He moaned against her, and Amy mewled.

"Sheldon, please," she breathed out, sounding desperate.

"What?" Sheldon whispered between licks against her. "What do you want?"

"Your-your fingers…"Amy murmured, having trouble getting the words out. Sheldon had been holding onto her thighs with his hands the entire time, and didn't think he had been gripping her too hard. Had he?

Or did she mean something else?

Sheldon kept up his lapping motions on her clit, and moved his right hand to her centre. He swiped his fingers through the mixture of his saliva and her juices quickly, and then brought them down to the entrance of her sex.

He pushed his index finger inside her, carefully feeling the inside of her and pumping at a leisurely pace. Amy whimpered loudly now. So, this was what she had meant. And Leonard as well.

With his fingers now stimulating her as well, the chorus of moans coming from Amy's throat was getting louder and more intense by the second. He felt her tremble under his tongue, and the walls of her vagina squeezed around his finger.

Amy inhaled sharply and groaned out his name in a breathy moan, and she convulsed against his mouth. Sheldon practically drank up the wetness that suddenly accumulated there, while Amy kept moaning softly. The contractions around his finger slowed down, and he extracted it from her as he moved his head away from her and slowly moved himself in an upright position.

Amy was flushed, and her facial features looked more relaxed than he had ever seen them. Her chest was still heaving slightly. Sheldon quickly looked away from her naked breasts. His erection was at a critical point right now. He wondered if it was the taste of her, her responses to him or feeling her come undone under his mouth and fingers that caused this extreme arousal.

He hoped Amy wouldn't notice, and if she did, wouldn't comment.

She blinked open her eyes slowly. Sheldon wiped his mouth on the back of his hand.

"Was this good enough for you to return to the realm of pure intellect again?" he asked.

Amy blushed under his gaze. She bit her lip and nodded quickly, closing her robe around her body in the procress.


27 days later

They had gone back to their usual way of interacting after that certain evening, and hadn't spoken about it since. Sheldon was glad, because the more he thought about it, the more confused he became. Not to mention aroused.

It was a Tuesday evening, and they ended up watching a movie with the others. The newest Marvel movie was coming out soon, and Amy had expressed an interest in seeing it with them in the cinema. Sheldon had smiled at her, her interest in his interests was very much appreciated.

They had decided to watch the first Captain America movie, since it contained the most plot points for the newest movie. Sheldon had already seen it twice, so he busied him with watching Amy's facial expressions throughout the movie.

It wasn't until Captain America was shirtless and pounding into a boxing bag that he noticed Amy's increased breathing and widened pupils.

Sheldon quickly did the math in his head and could only conclude what he had already suspected. Amy was at that point in her monthly cycle again.

The horny phase.

Ever so subtly, he grasped her wrist with his index and middle finger, ready to take her pulse. Amy turned her head to him questioningly.

Sheldon bent his head towards her ear, and lowered his voice so the others wouldn't overhear.

"Your symptoms have returned, Amy," he mumbled, and gave her a knowing look.

Amy gasped softly and blushed beet red.

"I'd be willing to help you out again," Sheldon said, and Amy's eyes widened in shock.

"But this time, reciprocity is in order, you vixen."
