The horniness is growing out of control, too

"I'm really glad to hear that, Doctor," Riley said.

"Please, call me Beth, all of you. Formality's always made me feel weird, and goodness knows we've got enough of that going on already."

"All right," Tab said. "You mentioned a treatment that could reduce my sperm counts," she went on. Beth reacted with a bit of surprise that it was Tab talking about sperm counts, given that she didn't have a dick, but caught herself before it became too obvious. She'd have to get used to the idea that these three were a single person, sharing a single mind. Apparently they were comfortable enough with what they were that Tab could talk about having a penis, and she imagined Toby could talk just as comfortably about having a vagina.

"Yes," tbe doctor confirmed. "It's less commonly used, but its preparation is standard training. If you have the necessary components I can have it ready very quickly. Then it's just a bit of local anesthesia around your crotch and I inject the compound. It'll take about an hour to set, after which we can run a sperm count test to see what effect it's had."

"How long does it last?" Toby asked and, further confirming Beth's notion about their comfort level in talking about themselves, he went on, "and will it affect my pussy?"

"It shouldn't have any effect on your vagina," Beth said. "Obviously, I can't be sure. I don't think there's any cases in the literature dealing with birth control for an intersex person as fertile as you."

"Well, I'm game," Tam said.

"There should be a complete stock list in the database," Riley said, gesturing toward the computer.

Ronnie walked around and sat in Tam's lap, grinding her ass against her lover's cock. "Want one last blowjob while you've still got all that seed?"

Even from behind it was clear that Beth had gone a little red.

"Get used to it, Doc," Riley said. "You're dealing with, depending on how you count, three or five randy university students. We're hot, we're horny, and when we're at home we're not gonna hold back."

"It's, well, it's not the oral sex itself I'm worried about. Doing it in the clinic might be a little unsanitary, though."

"We can go to the gaming room for a bit," Tab said.

"No!" Beth said, more sharply than she intended. "No, it's not that, I'm sure Riley's got perfectly good cleaning equipment to go along with everything else."

"I bet I know what you want," Ronnie said. "I bet you want to get some action for yourself." She hopped up and leaned maybe just a little too close to the doctor, who was just closing the database having confirmed that everything she needed was in stock. "Lucky for you I don't mind sharing."

"Well, I, uh," Beth said, her eyes flicking between Toby and Tam.

"You want to see whether there's a difference in our semen?" Tam said. "To be honest, I've kinda been curious too. Just haven't gotten around to blowing myself yet."

"God, is everything going to be about sex with you?"

"Randy university students," Toby reminded her.

"On spring break," Tab added.

"With three more walking sex bombs around me," Tam finished.

Riley and Ronnie had huge grins, but Beth flushed again.

"Beth, all I want to do is be able to fuck Ronnie, Riley and anyone else who's willing safely," Tab said.

"And masturbate safely," Toby added.

"At this point, sex is pretty much what I'm meant for," Tam said. "Whether I like it or not."

"I like it," Riley put in.

"Of course you'd like it," Ronnie said. "Good thing I like it too."

"Besides, doctor, if I can be candid, I know you've been thinking about my dick since you first saw me after this happened," Tam said, even though she hadn't existed then. "It would've been highly unprofessional for you to say anything, but here, if you want to fuck, just say so. Goodness knows we're all more than horny enough."

Beth had a silent debate with herself for a moment, but the weirdness of the situation, and the possibilities it presented, won out. Sure, she probably wouldn't be able to publish papers on the phenomenon if she got that close, but she'd also promised to keep this entirely confidential. If none of them were concerned about her medical judgment being compromised, well, boards of ethics couldn't punish what they didn't know about.

"Yes," she said. "Yes, I was a little curious when I first saw you, and the more so since Tam became a part of you."

"The only question, then, is whether you want to give me those blowjobs here, or in another room, then," Toby said.

--

Ronnie cleaned off Tam's dick while Beth sucked Toby's cock after injecting the sterilizing compound. All three bodies were clearly feeling the pleasure, having already climaxed from her first blowjob, and it didn't take long for Toby to blast a cumshot in the doctor's mouth.

Beth stood up, licked her lips, swallowed.

"You look a little disappointed," Riley said, she and Tab fingering each other's slits.

"I was hoping there'd be a noticeable difference," Bethany said.

"If there was a difference in the chemical composition," Tam pointed out, "mightn't that have skewed the results of the sperm test? But that came back normal, except for the higher count."

"Possibly, but since whatever's going on seems to be beyond the realm of ordinary science I wasn't ruling out that what should be two chemically-identical compounds might just so happen to have different tastes."

"We've been eating the same diet over the last few days," Tab said.

"Even so," Beth said. She stood up and sat back down in her chair, not bothering to put her top back on. After all, Tam had lifted her shirt to play with her nipples while Beth sucked her off, while Tab and Riley were completely naked. Casual states of undress seemed to be the order of the day.

"I don't know about any of you," Ronnie said, "but I'm feeling like a quick swim while we wait for that stuff to set."

Beth hopped up, as did Tam and Toby, but Tab and Riley stayed where they were. "You go on ahead," the rich owner said. "Just don't forget the cardinal rule of the pool."

"No swimsuits, you told us," Toby said. He shucked his clothes right then and there and padded off to the door. Beth stared after his huge, muscular form.

Tam and Ronnie had also stripped. "What are you waiting for, Beth?" Tam said, her massive dick swinging free.

"You really are all obsessed with sex," she said, but took off her pants and underwear.

"Hold on a sec," Riley said. She got up from where she had been sitting next to Tab and grabbed a bottle off a shelf. "All of you, apply this to your junk."

"What is it?" Ronnie asked, even as Beth recognized it.

"Depilation cream?"

"No pubic hair in the pool," Riley said. "Pain to filter out. That'll take care of it for good. Besides, it makes oral way better, if you ask me."

"All I have is this pubic hair," Toby said. "I'm not even sure if I can grow any otherwise."

"I'm going to apply it anyway, just to be safe," Riley said firmly. She got a container and smeared a glob of the cream around the base of Toby's cock. Seconds later, the hair fell out.

Tab, Tam and Ronnie all readily acquiesced, but Beth took the bottle for herself. "Sorry, I'm just not quite comfortable with that idea."

"Yet, I bet," Tab teased. Beth felt herself flushing again. She knew she'd fully succumb to the heightened libidos around her sooner rather than later. It didn't help that she herself was already feeling pretty horny.

"So no more of that?" Toby asked.

"None," Riley said, nodding. "Kills the follicles. Thoroughly irreversible."

"Not like I wanted to deal with the stuff if it ever grew in anyway," Tam said. "Now come on, we've got forty minutes to kill."

Toby and Ronnie helped each other shower, leaving Beth and Tam together. Beth felt herself get a little closer than she should to the tall woman.

"This is the dick you're really interested in, isn't it?" Tam teased her doctor.

Beth shook her head ever so slightly. There really wasn't going to be any use in trying to hide things. She might as well be just as open with the rest of them as they seemed to be with each other. "Yes," she admitted. "I've been wondering what it'd be like for you to fuck me."

"Good. Because I've been wanting to fuck you from the moment Tab walked into your office."

The pool was pleasant. Toby and Tam were clearly stronger swimmers than the other two, mostly on account of their size. It was clear to Beth that the others were just as uninhibited here as they were anywhere else they regarded as private, as there was quite a lot of brushing up and stroking and other such things.

"You can grab a tit any time you like, Beth," Ronnie invited.

"Just so long as we can grab yours," Toby added.

Beth didn't flush this time. She swam straight for Tam, and grabbed a handful of boob while awkwardly trying to give her a bit of a footjob.

"Is this how forward you want to be with all of your patients?" Toby said as Ronnie hung onto him from behind, pressing her own substantial breasts into his back.

"I think there's something about you that makes everyone hornier for you," Beth replied as Tam returned the massage.

"Probably just the people I'm horny for," the huge futa said.

"Patients shouldn't feel horny for their doctors," Beth reproved them.

"And doctors shouldn't feel horny for their patients, so we'll call it even," Ronnie retorted.

--

Beth jacked off Tam until she shot a load into the vial, just as the test machine chimed to indicate that Toby's analysis was done.

The doctor took the page out of the slot but didn't look at it, holding it in her lap.

"Come on, doc, we're all curious," Riley said. She and Tab had gotten each other off. None of them had bothered to dress again.

"So am I, but I want to see them side by side for a first impression."

A little tension built while Tam's vial processed, then Bethany took out the second sheet. She laid them on a table where everyone could see and flipped them over.

Tab let out a sigh of relief. "Worked better than you expected," she observed. "I've got two hard dicks and no risk of pregnancy."

Tam leaned over Beth, resting the doctor's head in her bosom. "Do you want it in your cunt or your butt first?" she asked.

"I'll decide later."

"Time for dinner," Riley decided. She extracted her phone from her pile of clothes and tapped out an order. "Steak and loaded potato salad sound good? Double for you three, of course."

Everyone nodded, and Riley pulled her clothes back on.

"Don't you just go around naked here?" Beth asked.

"The staff know not to barge into rooms I'm in, unless I ask for them," Riley said, "but I'm not about to let them track me through the hallways, and I'm not comfortable with most of them seeing me in the buff. If you are, I don't care, though."

Nonetheless Riley's confidence and presence led all of them to feel just a bit underdressed once she was back in her clothes, or at least what she passed off as such, Beth thought.

The food really was very well prepared. Beth enjoyed every bite of her comparatively small portion and felt quite full afterward.

"So are you two going to stay the night?" Riley asked. She made it clear what she preferred by adding, "The bed's big enough for six."

"I'll text Angela but I don't think she'll mind."

Beth hesitated. "Are you expecting me to move in permanently?"

"It'd be more convenient for you to be here when we wake up," Toby said. "All of my growth so far has been nocturnal."

"I should probably go get some things from my apartment, then, if I'm going to be here until you stop growing."

"We'll be in the theatre when you get back," Riley promised, deciding the night's entertainment unilaterally.

--

"You really like taking a busman's holiday," Tab said as the medical drama wrapped up. Somehow all of them had kept their clothes on for the entire time, though there was a lot of groping involved in watching the movies.

"I thought about trying to be an ER doctor," Beth admitted, "but it seemed too stressful."

"Well, this way you get to help with something way weirder than I bet you'd ever encounter in an ER," Toby pointed out.

All six disrobed as soon as Riley closed the door to the master bedroom. Beth could feel her nipples hardening and her pussy getting wet all over again, even though she'd seen the other five naked earlier in the day.

Tam picked her up. "Made a decision yet?" The others had wasted no time, Toby pounding Riley's ass while Tab and Ronnie ate each other out.

"Well it hardly seems fair to ask you to fuck two asses at once, and besides, you definitely can't get me pregnant now."

Tam was using the doctor's body as a fleshlight before they collapsed on the bed.
