9. Under Examination
Stanford Pines seemed a bit flummoxed on Tuesday afternoon when Dipper came in with a couple of test tubes and Pacifica. “Uh, you know each other,” Dipper said uneasily.
“You’re Stanford Pines,” Pacifica said with a smile. “The hunky gruncle!”
“Ah, and you are the Llama Lady,” Stanford said, grinning. “You have grown up to be a remarkably beautiful young woman!”
“Thank you. And I’ve been having sex with your great nephew.”
Ford face-palmed. “Dipper, another one?”
“It wasn’t my fault!” Dipper said.
“He’s right,” Pacifica said. “It was because I made a mistake and drank something that was meant for Tambry Rivera. She works for me, and, um, well. The drink had some of Dipper’s, um, in it, and it overwhelmed me. My libido just carried me away. Anyway, Dipper took these samples this morning. I, um, well, we’re all family here, and I’ll just say it. I had a female ejaculation today for the first time ever. The fluid and the, um, ejaculate are in these test tubes with lavender stoppers. They’re labeled, see? ‘VAG’ for the um, lubricant and ‘EJA’ for when I squirted.”
“You are remarkably calm about this,” Stanford said.
Pacifica shrugged. “What else should I be? I’m a Northwest. Hell, my father used to control me with a goddam bell!” She swallowed. “Sorry. Pavlovian conditioning, so I’d always master my feelings.”
“No one should be subjected to that,” Ford said, his expression serious.
“Right,” Pacifica said. “But there it is, and I’ve sort of learned while growing up that getting all emotional and ranting and complaining don’t get a person anywhere. It’s best just to accept problems and try to be cool and logical about them.” She smiled, though Dipper could see the shimmer of tears in her eyes.
“I like this young lady,” Stanford said softly. “Very well, in addition to these I’ll need a small blood sample from you and, if it won’t embarrass you too much, I’ll need to do a visual inspection of your vaginal walls and cervix.”
“Dipper said you’re a doctor,” Pacifica said. “Is it all right if he stays with me and holds my hand?”
“It’s fine with me if that’s what you want,” Stanford said. “Come this way. I’ll get into my lab jacket and gloves. And make sure the instruments are sterilized. Have you ever been examined with a speculum?”
“Oh, sure, when I got my birth-control implant,” Pacifica said. “Dr. Pines? Thank you for taking this so calmly and not yelling at us for this.”
“You’re welcome,” he said as he donned and buttoned his lab coat. “And I understand how powerful this alien aphrodisiac can be for humans.”
Ford had set up one of the labs as a medical exam room when he had checked out Tambry and Wendy. It included a standard doctor’s examination table and, thankfully, the heat in the room was enough to make it comfortable for the patient.
Stanford washed his hands and said, “Dipper, put a fresh sheet of paper on the examination table there, please. And then you’ll need to adjust the stirrups.” He air-dried his hands and then pulled on rubber gloves.
“Those must be hard to find,” Pacifica said, her eyes wide.
With a chuckle, Stanford told her, “I should explain, Ms. Northwest, that I was born resembling my twin brother in most ways. Two big differences, though: First, he has ten fingers, I have twelve.” He held up a hand and showed her the special rubber gloves that he had custom-made. “And the second way is that, while Stanley has more than once got into trouble because he is powerfully attracted to women, I didn’t share his feelings. In fact, I’ve never had a sexual attraction toward anyone, female or male. I am, in medical terms, asexual. I’m saying this to let you know that I will be dispassionate about this examination. Blood sample first.”
He took it from the inside of her left elbow. Pacifica held Dipper’s hand. She flinched just a bit and then a moment later said, “You’re good! That didn’t hurt except for a little pin-prick.”
“I try to be gentle in these things,” Stanford said, labeling the ampule of blood. “Still, one must suffer at least a small prick.”
“Oh, I’m used to lots bigger ones,” Pacifica said, grinning at Dipper.
“Nephew,” Stanford said, turning, “are you ill?”
“No,” Dipper said.
“That was a bad coughing fit, and your face is quite red.”
“Just something caught in my throat,” Dipper squeaked.
“Let me get the instruments, then. Pacifica, you will need to disrobe from the waist down, including your shoes. Then lie back and place your feet in these stirrups. Wait, I’ll give you a sheet to allow you some degree of privacy—”
“Oh, Dr. Pines,” Pacifica said, “Dipper’s seen everything I have already, from all sorts of angles. I don’t need a sheet.”
Nodding, Stanford laid out the speculum, a tube of lubricant, and a small flashlight on a metal tray. “First,” he said, “I’ll do a visual inspection of your external genitalia. I don’t expect to find anything of concern. You haven’t been suffering from any unusual sensations or pain, have you?”
“Only when that aphrodisiac starts to affect me,” Pacifica said. “Then I get sort of swollen down there and feel all tingly and get very wet. Nothing painful.”
“Nothing really out of the ordinary, then,” Stanford said. He used a voice recorder to say, “External examination of the vagina of patient PEN, age twenty, shows well-developed, normal labia. The coloring indicates healthy circulation. The clitoris is a third above median size, the sheath partly retracted.” He lightly touched it with a gloved fingertip. Pacifica twitched. “The patient has an excellent response to physical stimulation.”
Next he took up the speculum and showed Pacifica how it worked. “I’ll insert this in your vagina and then open it, like this.” He squeezed the handle. “That will let me see if everything is normal there. Again, I have no reason to anticipate any problems.”
With the aid of the penlight, he continued to record that Pacifica’s pussy lining looked strong and firm, with an excellent pelvic floor. Finally, he said, “This is the really personal part, but I need to do it. I can’t see things like your uterus and ovaries, so I’ll have to put two fingers inside you and then press your abdomen a little.” He smiled. “Neither you nor Dipper has had a prostate examination, and you’ll never need one, but I have! This is similar for ladies. It may feel a little uncomfortable, but it’s the best way for me to check out your inner workings.”
“Go ahead,” Pacifica said. “Um, am I kinky if I say I’m sort of wet already?”
“Not at all,” Stanford said. “Especially after your experiences with my great-nephew. All right, this is a gynecological lubricant.”
“I’m familiar with it,” Pacifica said.
“Um, yes. Now, just relax. You’re doing fine. Breathe slowly. This will cause you a little discomfort.” Pacifica closed her eyes while Stanford slipped his big fingers into her slit, and then pressed her abdomen, center, right and left.
“All done,” he said, stripping off the gloves. “I’ll return the speculum to the sterilizer. You may get dressed. I’m happy to report that everything is in excellent shape, Pacifica. I’ll give you some privacy.”
As soon as he left, Pacifica said, “Damn, I’m getting horny.”
“Not time yet,” Dipper said.
“Help me get my panties on?”
“Really?”
“At least I can give you a good look in bright light so you'll recognize the appearance of a healthy young pussy!”
Dipper did her the favor, and by the time Stanford tapped on the door, she was back in her clothes. “Very well,” he said. “Mason, the initial analyses are nearly finished. I’ve also analyzed the chemical makeup of the plant, and I’m confident I can neutralize the effects on you and diminish the young ladies’ attraction toward you. Except their feelings won’t go away. But what remains will be within the normal range of sexual attraction, not the extremes you’ve been experiencing.”
“How about his penis?” Pacifica asked, sounding a little anxious. “Will it get small again?”
“I don’t think so,” Stanford said with a sigh. “I’m afraid that physical changes like that and an increase in breast size, which you will likely experience, are difficult or impossible to reverse. You may notice that your breasts are growing and becoming more sensitive in the next few days. That won’t, um, go away, either. In fact, and I don’t know if this is a blessing or a curse, your vaginal and clitoral sexual sensitivity will remain elevated because you simply have more nerve endings now in the, um, appropriate areas.”
“I’d call that a win,” Pacifica said with a smile. She squeezed Dipper’s hand.
“Before you go,” Stanford said, “Please take these. I want each of the young ladies to use one at least once a week, beginning, oh, this Friday. As I understand it, you and Wendy are using IUD’s and Miss Rivera an IUS. These should be effective, even with my nephew’s increased production of semen. I don’t think super-potency of the sperm or ova is involved, but let’s maintain a check just to be safe.”
“Pregnancy tests?” Dipper asked.
“Yes, I’ve given you twelve of them. If there’s an indication of pregnancy from any one of the young ladies, she should come and see me right away. Even if it’s a ‘maybe.’ As I say, I’m nearly a hundred per cent sure there won’t be, but—”
“There’s shouldn’t be,” Pacifica said. “I’ve had boyfriends—” she bit her lip. “Let’s say lovers, before. I’ve never even had a false alarm for being pregnant.”
“All the more reason to test, just in case,” Stanford said. “Can you, Tambry, and Wendy all isolate over the next seven days or so? With Mason, I mean. Oddly, the females don’t seem to increase any pheromone generation, but the males, well, I gather they become irresistible.”
“I caught it from Tambry,” Pacifica said. “Well, indirectly. She had some of Dipper’s fluid with her and I drank it. She didn’t mean to do that.”
“Gruncle Ford, what if they shower and make sure they’re not carrying my scent around? Would they be able to go back to work? I don’t want to cost them their jobs.”
“Well—thorough showering and maybe the use of a strong toothpaste and mouthwash, along with perhaps use of a douche before they set out,” Stanford said. “I gather that if another girl has even a second-hand exposure to the pheromones, she becomes, ah, infatuated with it and desires to encounter the source?”
“Pretty much,” Pacifica said. “Oh, how much do I owe you?”
“Not one cent,” Stanford said firmly. “Though qualified, I am not professionally a certified physician. Anyway, this is an interesting case, and whatever I learn will be the best reward.”
In the car, Pacifica, wearing a hat and dark sunglasses, said, “Your uncle’s a cool old guy, Dipper.”
“He and Stanley both are,” Dipper said. “In different ways.”
Pacifica gave him a sideways glance. “You know, if you marry me, I wouldn’t mind if Wendy and Tambry kept, uh, seeing us.”
Dipper had jerked the steering wheel, and he quickly corrected. “Marry? Um, Pacifica, you’re great, and sexy as hell, and you’re beautiful, and I love making love—”
“Say fucking me,” she replied contentedly. “And eating me out and having me suck you off. I’m comfortable with all that. You know, when your uncle had his fingers inside my pussy, I started to feel worked up. Started to want some action. Are you worked up? Hmm, what am I smelling? You’re not totally professional and dispassionate like your uncle at all, are you?”
“Please,” Dipper said. “Talk about something else. Talk about baseball or the economic projections for the next quarter or how we fought Bill Cipher, but not about sex.”
“Okay,” she said. “I’m kind of excited, though. Mind if I warm myself up?”
“I . . . guess not,” he said.
She reached between her legs and started to massage her pussy.
“You’re going to get your underwear all wet,” he warned.
Smugly, she replied, “No I won’t. I took them off while you were putting your coat on. Ahh, yeah, that feels like a healthy young woman’s vagina. Nice and tight. Let me see how that clitoris is reacting. Ooh, nice reaction! And the flow of vaginal lubricant is very impressive.” She sucked two of her fingers and smacked her lips as Dipper began to breathe hard. Then she said, “Next I want to observe how everything holds out when a guy with a real big dick is getting me all worked up. You’re speeding, Dip!”
“Damn right I am,” he said, flooring the accelerator.
Over the next days, the four of them didn’t have sex 24/7, but often enough. They established a kind of routine: In the mornings, Tambry and Pacifica would get the lion’s share of what Dipper produced and then they would go to work. At a few minutes before noon, Wendy came back from her job and gave him an enthusiastic blowjob, swallowing his entire load. Then she very carefully showered, paying special attention to her pussy, outside and in, brushed her teeth, and gargled just so she wouldn’t be radiating the pheromones in the office—she had three women employees who were always about, and the last thing Dipper needed was more women following her home and eager for his cum.
At five o’clock, Tambry and Pacifica would return, ravenous for a session with Dipper. Pacifica liked to fuck, and usually Dipper would shoot most of his cum into her, with a last jet or two left over for Tambry and Wendy to share. Then the two would go down on Pacifica, suck up some of the surplus, and give it to Pacifica via mouth-to-mouth.
Early on Friday morning, the three girls followed Stanford’s orders and unwrapped their pregnancy-test kits. All of them had done this before, but Tambry asked if she could hold the sticks while the others peed on them.
“I didn’t know you were so weird,” Pacifica told her.
“Oh, yeah, I like to hold Dip’s dick while he pees, too!” Tambry said brightly. “I’ll show you later!”
So in the bathroom Pacifica and Wendy peed on tests that Tambry held for them, and then she held one for herself. After the required three minutes, Pacifica said, “Negative for me.”
“Me, too,” Wendy said.
And Tambry sighed with what sounded like satisfaction. “Nothing here, either. I’m not surprised. I can feel my period coming on.”
“You too?” Pacifica asked, sounding startled.
“Uh, make that three,” Wendy said. “Probably tomorrow or the day after for me.” She frowned. “But it’s like a week early.”
“Little early for me, too,” Tambry said.
Dipper had overheard their conversation. “Um, I need the bathroom for a minute,” he said from the doorway. “And there’s nothing really weird going on. You three have kind of bonded, and when girls do that, their periods synch up.”
“How do you know that?” Pacifica asked suspiciously.
He shrugged. “I had Human Biology in college. Now I really need to pee—”
“Dibs on his dick!” Tambry crowed. “Girls, you want to watch? It’s interesting!”
“Yeah, I’m in,” Wendy said.
Pacifica gave her a shocked look. “Ew! That’s perverted! But I’ll watch, too.”
“Nobody’s going to ask me?” Dipper said.
“You’re outvoted,” Pacifica told him. “Why are you even wearing shorts? Whip that big guy out!”
He felt strange about it, but when a guy’s gotta go, a guy’s gotta go, so as Tambry aimed his penis for the toilet, the other two girls watched.
“Do all guys pee that hard?” Pacifica asked, sounding impressed.
“I don’t watch other guys peeing,” Dipper said.
“Wait till the end,” Wendy said, giggling. “There! One, two! Three last shots. Just like he’s cumming, right?”
“Ooh, look, he’s getting bigger,” Tambry said. “Time for breakfast!”
“At least let me wash!” Dipper pleaded.
He lay in bed as Pacifica and Tambry eagerly started sucking his now stiff dick. Wendy sat beside him, admiring the view, and that got her milk started, so she leaned over and let Dipper drink it up. That gave her a mild peak—two, in fact—as Tambry and Pacifica gulped Dipper’s morning rush of cum.
“Mm,” Tambry said, worming her way up the bed to give Wendy an open-mouthed kiss so she could get a good taste, too. “The first one in the morning is always the best!”
“So thick and creamy,” Pacifica agreed. She was still nuzzling his softening dick and his balls, searching for any lost droplets. “Dipper, in the next few days if we go all PMS on you, you’re not gonna be mad at us, are you?”
“As long as there’s no hitting or screaming involved,” he told her.
“Oh, she’ll scream,” Tambry said.
“Will not!” Pacifica came up to let Wendy suck on her tongue. When that was over, she pouted a little. “Okay, I won’t scream or hit. But for the next, like, four days we can’t fuck. What am I gonna do?”
“My periods never bother me much,” Tambry said. “I like sucking as much as fucking!”
“Mine used to run five or six days,” Pacifica said. “They got shorter since I had my implant. Now three days and I’m good to go.”
“Too much information!” Dipper said, covering his face with a pillow.
“Aw, he’s shy!” Tambry said. She patted Dipper’s dick. “Don’t worry, big guy, we’ll take care of you even if we won’t let you fuck us for a few days.”
Then they all went off to work, Pacifica and Tambry each taking with her a protein drink with special additives—along with a small bottle of the strong mouthwash that Wendy used. That morning Dipper immersed himself in writing up his research, having to do with the paranormal animals, entities, places, plants, and places of Gravity Falls, not with sex.
But his growing desire distracted him shortly before noon, and when Wendy pulled in, he had already stripped. She did the same in record time, pushing him back onto the bed and lying on top of him, his dick trapped between her thighs and against her slippery pussy. “Man, I’ve been looking forward to this all morning,” she said. “Hey, I want to try something different, ‘cause we’ll have to get through the next few days being inventive. You okay with that?”
“Whatever you want to do,” Dipper told her. “Only hurry!”
“Okay, first so I’ll get off, I want you to put this inside me.” She handed him a device that looked like an egg, except it had wires and a battery box attached to it.
“This goes in—”
“My wet pussy,” she said, lying back on the bed and moving her knees apart. “Small end first, and get it in there good and deep.”
“A vibrator,” he said.
“Yeah. I’m gonna order a remote-controlled one, and I can wear that even in the office, but this one has the switch on the batteries. Go ahead and put it in, I’m ready!”
Dipper watched Wendy’s beautiful pussy accept the egg, the pink lips spreading as he pushed it inside. “You smell really nice,” he told her.
“Aw, I’m turned way on. Little deeper. Yeah, there. Okay, flip the switch on so I can make sure I can keep it inside.”
He did, and it began to buzz. He asked, “How’s that?”
“Good!” Wendy said, arching her back. She chuckled. “Hey, man, I see your dick’s throbbing. Here’s what we’re gonna do.”
What they were going to do, and did, was a tit-fuck. She knelt on a pillow, her heels pressing into her buttocks, while he stood and put his shaft between her tits. “Never done this before, have you?” she asked, tilting her head to look up at him while she trapped his dick between her soft, warm breasts.
“No,” he said. “But I love the way you look doing it. And the way it feels.”
Grinning, the redhead started to massage him. “Ooh, yeah, the vibe’s getting me ready for the big O. Listen, you gotta work for it, Dip. Fuck my tits. And warn me when you’re ready to shoot. I’m feeling greedy, and I want it all in my mouth, not on my bedroom ceiling!”
As Dipper thrusted, he felt a warm lubricant oozing over him. He realized Wendy’s nipples were leaking milk, and it seemed almost as slippery as pre-cum. He could tell that Wendy came twice, from a combination of the pheromones in her nostrils and the vibe deep in her pussy. Then he grunted, “Gonna cum!”
She capped his dick with her mouth, holding onto his shaft with both hands, and instantly the gush began. With practice she had become much more expert at trapping his semen without spilling it, and she gulped it down, shaking from her own third, and greatest, orgasm.
“Whoa,” she gasped, pulling the egg out. They stretched out on the bed together. “That was epic. My stomach feels full!”
“I think I like tit-fucking,” Dipper told her, nibbling her throat. “Want me to go down on you?”
“Um, yeah, ‘cause tomorrow it’ll be too messy. That’s sweet of you. Dipper, I love you.”
“You know I love you,” he said.
Her pussy was fragrant, hot, and, as far as he was concerned, delicious. They had gone into the sex so wildly, with such heat, that though it satisfied both of them, it left them half an hour for kisses, caresses, and cuddles. “The more we do this,” Wendy murmured into his ear, “the less I’m sure I want your uncle to stick us with his needle.”
“It’s great,” he agreed. “But—it would be too hard to live our lives like this all the time. And also, you know, there’s the scent.”
“Yeah,” she said sadly. “Poor Dip. You’re a prisoner until you can stop making those pheromones. You can’t go near any girl without making her all horny.”
“As long as I still make you horny,” he said with a smile.
“Don’t worry about that,” she said, checking the time. “Have to go to work again, so I ought to get dressed. But don’t worry about making me horny, man. You got me. You got me good.”
