Charlotte watched the pingpong ball bounce across the table and into a cup. There was a chorus of “oohs,” and her best friend, Izzy, downed her second cup of the night. The man across from her, she thought his name was Liam, cheered. Why he was so proud, Charlotte couldn’t understand. He had exactly one solo cup left on his end of the table. It was almost impossible to beat Izzy at beer pong, even when she was blackout drunk.

Sure enough, Izzy’s next throw landed easily. Another bout of cheering insued, and Izzy took a bow before coming to sit next to Charlotte on the couch.

“Nicely done,” Charlotte complimented, grinning at her friend.

“You want in on the next round?”

Charlotte scoffed. She had told Izzy three times in the last hour that she had work in the morning. Izzy did too, of course, seeing as they worked at the same law firm, but she was much more laid back when it came to weekends. Although, she supposed, it wasn’t technically a weekend.

“Come on, Char,” Izzy whined. “It’s Halloween, you’re supposed to drink. I’m not letting you go through this night sober.”

Charlotte let out a long sigh, but she was smiling at her friend. “One drink,” she relented. “At midnight. No more.”

Izzy let out a weird sort of squeal and jumped off the couch. She disappeared into the off-limit upstairs of her house. Where she was going, Izzy didn’t know. She just shook her head and waited.

It was ten minutes until midnight when Izzy returned carrying a red solo cup and what looked like a fireball without the label. She handed the latter to Charlotte, grinning.

“I was thinking beer,” Charlotte said, scrunching up her nose. She didn’t like shots.

“This is special,” Izzy insisted. “Read it.”

She pointed at a long tag attached to the bottle with a piece of red string. Charlotte flipped the tag around and read it aloud.

“Liquid libido. Charming.” She flipped it back over and read the back. “Have the libido of a man for seventy-two hours, or until you- Jesus, Izzy!”

“What?” Izzy shrugged. “You haven’t been laid in almost a year.”

“Neither have you,” Charlotte reminded her.

“Ben and I are waiting until marriage. It’s different.”

Charlotte couldn’t understand that. The two were practically already married, and had been since tenth grade. Izzy, despite all of her antics, was the holiest person she’d ever met in that regard.

Charlotte, on the other hand, was the opposite. From high school up until last year, her first year out of college, Charlotte had been bordering sex addiction. And yet, she hardly ever drank.

Charlotte looked at the tag again and read the back in her head. Have the libido of a man for seventy-two hours, or until you orgasm inside another person’s vagina or anus.

“You gave me a charlatan potion.”

“I gave you a magic potion,” Izzy said in a wide-eyed whisper. Then, normally, “And someone else gave it to me, first. I figured you’d use it better. Relax, I smelled it. It’s just alcohol.”

“Then why didn’t you drink it?” Charlotte asked skeptically.

“Because I thought it would be funny. Do you want it, or should I get you beer like a loser?”

Too late; the clock was only two minutes away from the witching hour. She unscrewed the shot, and Izzy smiled happily.

They watched the clock together, counting down the seconds until midnight. When the minute hand finally met the hour hand, they toasted. Izzy raised the cup to her lips, and Charlotte followed suit with her shot.

The shot tasted awful, as she had expected. It burned the back of her throat and sent tingles through her entire body. She grimaced as Izzy smiled, wiping her mouth with the back of her hand.

“That was repulsive,” Charlotte said, coughing. Izzy just shrugged.

“Do you feel better, though?”

Charlotte did, in fact, feel a pleasant sensation coming over her. It spread through her body in ripples before falling, falling, falling…

Charlotte’s smile dropped. The strangest feeling was… and it was growing…

“Charlotte?” Izzy’s concerned voice sounded far away. “Charlotte, are you okay?”

Charlotte turned and fled up the stairs. She didn’t know what was happening, but she had to make absolutely sure what she thought was happening was not happening. She could hear Izzy following her up the stairs. She turned the corner into her friend’s bedroom and shut the door.

Charlotte feverishly unbuttoned her pants and pulled down the zipper. She had to try a few times, because something was…

She finally got the zipper down and pushed her pants and panties down to the floor. Sure enough, something sprang free. A long, thick, rigid, penis. And it was attached to her. All she could do was stare with her mouth open until Izzy knocked on the door.

“Charlotte, hun? What’s going on?”

“Izzy!” Charlotte screamed. The door banged open, and Izzy exploded into the room in a panic, hands raised. They fell along with her jaw when she peeped the sight in front of her.

“Woah,” Izzy said, everything slack. “Who’s your friend?” Charlotte glared at her. This was not the time to be making jokes.

“What the actual fuck did you do, Izz?” she screeched.

“I- I..,” Izzy stammered, “I guess it… worked? I didn’t know you were trans. I’m an ally, by the way.”

“I am not trans,” Charlotte shrieked, fury rattling her senses. “We’ve literally changed in front of each other. Your magic fucking potion gave me a dick!”

“Okay,” Izzy whispered, seemingly to herself. “Okay. Oh my God.”

“Fix it!”

“I’m thinking!”

Meanwhile, Charlotte’s friend was somehow getting harder. She groaned. Realizing she still had the shot in her hand, Charlotte read the tag again.

“Wait,” Izzy said, pointing at the tag in her hand. “It said you can make it go away, right? If you orgasm? So we just have to-”

“Inside someone, Izzy! I have to come inside someone!”

“Well, we’ll just have to find you someone to fuck,” Izzy said, as if that was the most logical conclusion.

“I am not letting someone see me like this.”

“What other choice do you have?”

Charlotte read the tag again. Have the libido of a man for seventy-two hours, or until you orgasm inside another person’s vagina or anus.

“Seventy-two hours,” she whispered. 

“What?”

“It lasts for seventy-two hours,” Charlotte said, louder. “That’s three days. I can make it three days. I can.”

“You’d rather go three days with a raging boner than let someone see you like this?” Izzy asked, shocked.

“What am I supposed to do?” Charlotte hissed. “If I try to hook up with a random man, chances are he’ll take one look at this thing and run. And it’s not like there are a whole lot of options for queer women around here.”

Izzy didn’t answer. Her eyes were trained on Charlotte’s penis, completely dumbstruck. She swallowed hard.

“In the meantime, I’ve gotta figure out how to hide this thing.” Charlotte pulled her jeans back up, stuffing the sensitive penis into her panties. She groaned, but managed to zip her pants. Unfortunately, this proved to be extremely uncomfortable. The dick pushed hard against her tight pants, trying its best to break free.

Shaking, Charlotte tried to ignore the pressure, but it was too much. She palmed her crotch, but it offered little relief. She looked down. Not only was the situation uncomfortable, but it was also extremely noticeable. Her jeans tented at her crotch, showing the outline of the mass beneath.

“This isn’t going to work,” Izzy said, her voice back. “I think… I think you need to masturbate.”

“It said I have to come inside someone, Izzy,” Charlotte whimpered. “Masturbating isn’t going to help.”

“It won’t make your dick go away, but the boner should,” Izzy insisted. “Come on. It’s worth a shot.”

Charlotte sighed. She unzipped her pants and, once again, pushed them down so that her penis sprang free. Then, ever so softly, she began to stroke. Back and forth, back and forth. It felt good, really good, but her skills were clumsy at best. She knew it wouldn’t be enough. Charlotte growled in frustration.

“I can’t. It’s too… I don’t know. I can’t come like this.” After a moment of thought, she asked hesitantly, “Can you help me?”

Izzy’s eyes widened and snapped from Charlotte’s dick to her face. “Help you?” she squeaked. “Like… help you? Isn’t that cheating? I can’t do that to Ben, Char.”

“This is a medical emergency, Izzy,” Charlotte pleaded, still stroking the dick. “Please. You got me into this mess. Help me out of it.”

Izzy’s eyes closed, and she let out a long breath. “I did get you into this, didn’t I? Okay, fine. I’ll do it.”

Izzy sank to her knees, and the sight of it set off a swarm of butterflies in Charlotte’s stomach. She pushed them away. This is a medical emergency, she reminded herself. That’s all.

Izzy took Charlotte’s engorged cock in her hand and began to slowly stroke. It already felt better than Charlotte’s own hand, and then Izzy licked the tip where a bit of precum was oozing out.

“Just get it over with!” Charlotte begged. What she wanted to say was, Stop teasing me! but that felt far too sexually charged. She had to stay cold. Clinical. But then Izzy’s mouth slid down her shaft, and Charlotte couldn’t help but moan. It felt incredible. Izzy’s hot tongue slid around the throbbing cock as she sucked her friend off.

Charlotte felt her hips begin to move without her permission, thrusting herself into Izzy’s mouth. She moaned like a thing possessed, and one hand slid down to grab the hair on the back of Izzy’s head.

It was clear this wasn’t Izzy’s first rodeo. While she may have been saving herself for marriage, there was no doubt she and Ben had been down this particular road before. The mixture of firm pressure and tender motions felt so incredible that Charlotte soon began to feel something building deep inside of her. When Izzy brought a hand up to softly massage her balls, Charlotte knew the end was imminent.

“I’m going to come,” Charlotte choked, giving Izzy the chance to get out of the way. Instead, she pressed her head down so far that Charlotte felt the cock hit the back of her throat.

She couldn’t help it. Charlotte let out a guttural cry, and the warmth in her balls surged through her rigid cock, filling Izzy’s mouth with her come. Izzy gazed up through her eyelashes, lips tight around it as she sucked her friend dry.

Charlotte nearly collapsed, her knees weak as Izzy pulled away, swallowing the evidence of their transgressions. She flicked her tongue against the end of Charlotte’s softening cock, giggling when she flinched.

“Wow,” Izzy said. “That was surprisingly hot.”

“Izzy!” Charlotte gasped, a deep blush taking over her face. Izzy just laughed, pushing herself to her feet.

“Well, looks like you’re all set now,” she said, eyeing the shrinking penis. “You’re staying here tonight, yeah? I don’t want you going home alone and being… stuck. If it happens again, I mean.”

“Yeah, I’m staying,” Charlotte agreed. Izzy nodded and turned to leave, but Charlotte grabbed her wrist.

“Thank you, Izzy. I don’t know what I would have done without you.”

“You wouldn’t be in this situation without me,” she admitted, wincing. “But I’m glad it worked out. Just don’t get horny again.”

Charlotte just rolled her eyes, because how on Earth was she supposed to control that?

Later that night...

Charlotte tossed and turned in the guest room, pulling the covers every which way as she tried to get comfortable. Every time she felt herself drifting off, an image of Izzy’s teasing smile, her short dress, her pink lips wrapped around Charlotte’s new cock, invaded her mind.

She couldn’t help it. Charlotte had been out as bisexual for years, and she could admit that her friend was attractive, but she’d never allowed herself to really look at her like that. Now that she’d had Izzy’s mouth on her, though, it was impossible to ignore.

Charlotte reached down and adjusted her pajama pants around her new toy, and… god. Even the slightest bit of contact had heat rising in her body. She rolled onto her stomach. Not again, she thought to herself. Not now. Stop it, please stop.

But it was no use. The cock, her cock, had woken up, and Charlotte could feel it growing. As it did, more images flashed through her mind, even as she tried desperately to push them away. Izzy with Charlotte’s cock in her mouth. Izzy’s mouth on her tits. Izzy’s eyes as she gazed up at her, a truly sinful type of bliss painted across her face.

Charlotte groaned and shifted again, lying on her back and angrily pulling down the soft pants so she could palm her throbbing dick.

I can do this, she told herself. I don’t need Izzy’s help.

Tentatively, she took the cock in her hand, rubbing slowly up and down. It was just as hard as it was when it had first appeared, and a bit of precum oozed out the slit in the purplish head. Charlotte moaned as she sank into a clumsy rhythm, her eyes falling shut as she finally let herself imagine whatever it took to get this over with.

“Whatever it took” turned out to be Izzy from behind, smirking over her shoulder as she bunched up her dress, revealing her firm ass to Charlotte’s imagination. In her head, Izzy reached back and pulled at her cheek, flashing her little pink pucker for only a moment.

Charlotte moaned again, imagining sucking on her own thumb before popping it into that tight hole. Her cock throbbed at the idea. In her mind, Izzy even let her rub the tip of her cock between her cheeks, let her push the head in, let her push her down on the bed as she fucked her tight hole.

Charlotte’s clumsy rhythm picked up speed, but it wasn’t enough. She needed more, needed Izzy’s hot mouth wrapped around her again. She whined, shifting again as she tried to work herself into the orgasm she so desperately craved.

“Charlotte?”

The soft voice came from the doorway to the guest room. Charlotte’s eyes flew open, and she instinctively tried to cover herself as Izzy stepped into the room. She reached over and clicked on a desk lamp, flooding the room with a dim yellow glow.

“What do you need?” Charlotte snapped. Izzy raised an eyebrow.

“Sorry,” Charlotte muttered. “I’m a little worked up.”

To prove her point, Charlotte pulled down the covers. Her cock stood rigidly, as if waving hello. Izzy’s cheeks turned pink.

“I heard,” she admit, coming to sit on the edge of the bed. “My room is just down the hall. It’s a good thing Ben’s with his buddies tonight. I don’t think I would have been able to explain away sounds like that, and he never would have believed me if I told the truth.”

“I just can’t get it to go down,” Charlotte whined. She didn’t have it in her to be embarrassed that her friend had heard her masturbating. Not after what they’d already done. “It’s so much weirder from this angle. Besides, I haven’t been with a guy in years.”

Izzy nodded. She reached out a hand and rubbed Charlotte’s thigh, almost comfortingly. They stayed like that for a minute, Charlotte’s cock growing even harder, if that was possible.

“I was thinking,” Izzy began hesitantly, “maybe there’s more I can do to help.”

Charlotte furrowed her eyebrows. “More than sucking me off? Like what?”

The blush crept from Izzy’s face down to her neck, and she ducked her head.

“I can make it go away,” she muttered. “I could let you… you know…”

Charlotte shook her head automatically. “I’m not going to take your virginity, Izzy. I would never make you do that. Don’t do something you’re not comfortable with just to fix a mistake.”

“I meant the other way,” Izzy admitted sheepishly. Charlotte raised an eyebrow.

“You want me to fuck your ass?” She asked, blunt as ever. “That’s not cheating to you?”

“It’s not cheating if it’s for medical reasons,” Izzy protested. “Besides, Ben is the one who wants to wait, not me. I just don’t want to break my hymen and have him know when we do finally have sex that I lied to him.”

“So you want me to fuck your ass.”

“Whatever. It was just a suggestion.” Izzy threw her hands up, exasperated. She stood, crossing her arms as she made to leave. Charlotte scrambled up, grabbing her shoulder and preventing her escape. Images from her fantasy came back full-force. Now she had the chance to make it a reality? Charlotte wasn’t about to give that up.

“Wait, I was just kidding!” she said quickly. “Really. You’ve got a great ass. I’d love to.”

Izzy grinned. “I do have a great ass, don’t I?” Charlotte rolled her eyes.

“Go get the lube.”

When Izzy returned, a pink bottle of lubricant in her hand, Charlotte’s dick jumped once again, at attention like it knew what was about to happen. Izzy crawled onto the bed, needlessly sexy as she turned so her ass faced Charlotte, covered only by her lacy blue nightgown. She handed Charlotte the bottle.

“Are you sure about this?” Charlotte asked. She couldn’t help it; this whole thing was just too weird, even though her body wanted it like nothing else.

“I’m sure,” Izzy sighed. “Pass me a pillow.”

She did, and Izzy adjusted it under her chest, leaning down so her head was on the mattress and her ass was in the air. Charlotte swallowed thickly. She wanted nothing more than to impale her friend with the disaster she caused, but she was frozen.

Izzy looked so good like this. The light blue nightie barely covered her perfect ass, and her back arched in a way that had Charlotte wanting to press her down further, see how much she could take.

“Are you done staring?” Izzy asked. “Come on, Char. Do it.”

Just like that, all hesitation evaporated. Charlotte pushed herself to her knees, cock pushing proudly in front of her. Slowly, so slowly, she lifted Izzy’s nightie, finding nothing beneath to obstruct her vision of her puffy pink pussy and puckered asshole.

“Jesus, Izz,” Charlotte breathed. “Do you always go to sleep with no panties on?”

Izzy chuckled. “Usually, yeah. It’s more comfortable.”

Well, now it was making Charlotte uncomfortably hard. With shaking hands, she flicked open the cap and drizzled a generous amount of thick clear lube down the center of Izzy’s skin, watching as a bead slid down towards her pussy. Izzy flinched, sucking in a breath at the sensation. Charlotte dripped a bit more on her hand, coating a finger before reaching for her friend.

Charlotte slid her finger in gentle circles around Izzy’s hole, teasing the entrance before pushing in with her middle finger. Izzy immediately tensed up, but as Charlotte eased her finger into her, the muscles relaxed, and she let out a long sigh.

Dipping another finger into the tight heat, Charlotte scissored and swirled her them, getting her friend ready for what was to come. When she felt Izzy start to push back into her, grinding against the intrusion, she knew it was time. She pulled her fingers out, and Izzy whimpered at the loss before gasping when Charlotte pressed the head of her cock to that same spot.

“Are you ready?” Charlotte asked, her throat tense as she resisted to urge to plow into her friend.

Izzy nodded. “Go slow.”

Charlotte gave her cock a generous coating of lubricant before pushing the head into her friend’s tight little ass.

Izzy gasped, letting out what might have been an Oh my god! as Charlotte entered her. Charlotte, on the other hand, saw heaven. Her friend was so perfectly tight, her hole gripping Charlotte, sucking her in once she made it past the ring of resistance.

Charlotte made a noise that was far from dignified as she began rocking her hips back and forth, easing in just a little more with each forward thrust. It felt so good, better than she would have ever felt possible. She finally understood why men complimented her on her tight pussy. The way it gripped her cock made her balls twitch and yearn for attention.

“Fuck, that’s good,” Izzy groaned, and Charlotte had to agree, though she couldn’t bring herself to voice it.

Charlotte eased herself in inch by inch, her breath shaking on every exhale. Izzy's body had gone still and tight beneath her, the ring of muscle clutching at her like a fist. Halfway was where it got hard, where the widest part of her pressed against the resistance, and Izzy made a small, wounded sound into the mattress.

"Breathe," Charlotte said, her voice raspy. "Breathe for me, Izzy."

Izzy blew out a long, shuddering breath, and her body opened. Charlotte sank the rest of the way in, all the way to the hilt, and they both groaned at the same time — Izzy's high and thin, Charlotte's low and wrecked. She stayed there a moment, hips flush to Izzy's ass, her whole body trembling with the effort of not moving.

"Okay?" she managed.

Izzy turned her face out of the pillow. Her cheeks were red, her hair a mess, but she was grinning through it like a lunatic. "More than okay," she said. "Fuck. That's… full. Really, really full."

“Just for medical reasons, right?” Charlotte teased. Izzy groaned, rocking back against her. Charlotte got the message and began to move, slowly pumping her cock into Izzy’s gripping hole.

It felt so, so good. Each thrust was slightly harder than the last until Charlotte was slamming into Izzy with an alarming amount of pressure. Izzy didn’t seem to mind. She arched her back, reached back a hand, and moaned obscenely when her fingers touched her clit.

Charlotte leaned over her, reaching up under her nightgown and grabbing at her tits, the perfect handful for Charlotte to play with. Izzy whined when she pinched a nipple between two fingers, and the sound went straight down Charlotte’s spine.

“I’m close, Izz,” she said, voice ragged and needy.

Izzy didn’t respond. Her breaths were uneven, and little whimpers slid out of her with every thrust. The ring of muscles tightened around her, and with a shuddering gasp and a long cry, Izzy came wrapped around Charlotte’s dick.

The sight pushed Charlotte over the edge. With a series of heavy groans, she came hard, slamming into Izzy’s ass over and over again until she couldn’t move. She barely caught herself on her hands before she crushed her friend.

“Fucking hell,” Izzy muttered. Charlotte couldn’t help but agree.

Pushing back onto her knees, Charlotte slowly pulled out of her friend, mouth watering when she saw the gaping hole she left behind. As soon as she was out, she felt the strangest sensation. The cock was shrinking, past a deflated state and smaller, smaller, smaller, until with a final tuck, it slid into place and became Charlotte’s clit once again. Her mouth fell open, then curved into a smile.

“Izzy, it worked.”

Izzy wasn’t paying attention. Her head was on the pillow, eyes closed. “Hmm?”

“It’s gone. It disappeared. Izz, look at my pussy!”

Izzy cracked an eye open. “That’s a sentence I never thought I’d hear from my best friend.”

Charlotte slapped her ass, and Izzy yelped. Charlotte snickered as Izzy slowly pushed herself up, eyeing Charlotte’s brand-new cunt. To Charlotte, it had never looked so good.

“So… what now?” Izzy asked.

“Well, right now, I’m going to sleep,” Charlotte said. Izzy rolled her eyes. “And tomorrow morning, I’m calling out sick. I think I’ve earned a day of rest. Don’t you agree?”
