The Backpack ~ An erotic fantasy by Jessica Presley (Patreon)

Heather and Jodi sat in the third row of the Kia Telluride SUV with their earbuds in and eyes locked down on their phones. The ride from UC Santa Barbara to Big Sur had been smooth so far. They left at 9am and by late-afternoon were winding their way up the road to their destination. 

They had made several stops along the way to take selfies for their Instagram accounts, much to the shagrin of the guys they were traveling with. But they acted as patient as they possibly could have and let the girls do their thing.

Between Heather and Jodi, resting on the floor, was a black backpack. It was nondescript, so much so the guys didn’t even notice it when Heather climbed in, sat in her seat, and set it down. It was a secret passenger of sorts.

Their own personal bags, which were pink and girly, were in the rear luggage area. Although it was just a weekend getaway, they had packed more than they needed. But they kept the black backpack they had specially prepared close to them. In it were items they thought would add some fun to the weekend. 

Jodi paused the video she was watching on her phone and looked down at the backpack. She then tapped Heather on her bare leg. She glanced at it too, then turned back to Jodi and nodded with a smile. They’d reveal what was inside once they got to the house.

Mark was driving. He had short blonde hair and a clean shaven face. His look was very preppy. His goal was to get an internship at a tech company and work his way up.

Jordan was in the passenger seat. Family was rich. This was his car but he hated driving. He had curly dark hair and Mediterranean features.

Ty and Randy were playing Slap Jack in the middle seats. Ty had brown hair and piercing blue eyes. He lifted weights but wasn’t overly bulky. Randy had a surfer look to him. Sun-bleached longish hair and a tan. He was skinny.

It was a friendly group. No one had ever hooked up with each other so there was no baggage or strange feelings about one another. 

The girls had gotten to know Jordan in their sociology class and had a few laughs. The hope was those good times would keep rolling. The girls felt comfortable with the guys. Enough so to bring along the black backpack with them.

They pulled up to a beautiful Mid-Century style home. It was located in the Big Sur Valley and stood 600 feet up from the Pacific Ocean. It lay between the Ventana Wilderness Area and Los Padres National Forest. 

Jordan’s father owned the 4-bedroom estate and rented it out to travelers. But this weekend it was available for use. 

Everyone got out of the SUV and took in the house and the setting. Jordan, who had seen the place plenty of times before, went to the back to pop the rear hatch and start unloading bags. 

“This is amazing!” Jodi said with a little girly jump of excitement. 

She walked around and took selfies of herself in various spots around the residence. Heather took notice and started doing the same thing. 

Mark went over to help Jordan out with the bags. He was handed a piece of luggage and looked over as Jodi and Heather posed with a view of the ocean in the background. He shook his head as he watched the girls do their thing.

“You’d do the same thing if you were them,” Jordan said with a laugh.

“Having a vagina has to be a curse,” Mark said with a sly grin.

“I don’t know. Seems like they’re having loads of fun to me.”

After everyone had a chance to look around the grounds surrounding the house they went inside. Jordan had put their bags all neatly lined up next to the front door. All except one. Jordan held the black backpack up.

“Anyone know whose this is?” he asked.

Heather rushed up and grabbed it from him. His response was to laugh. Her sudden concern and claim of ownership seemed odd to the guys.

“Well ok, Heather. Must be pretty important. You carrying feminine hygiene products in there?”

“Maybe it’s weed!” Ty exclaimed.

“Wait, you didn’t bring any?” Randy asked.

“I thought you were supposed to,” Ty answered in a suddenly deflated tone.

“Oh shit, that’s a bummer,” Randy said.

“No, it’s better than that,” Heather said.

“Better than weed? C’mon,” Randy scoffed.

“Trust us,” Jodi said. “It’s going to make the weekend even more amazing. Show them.”

Heather smiled as she unzipped the backpack and brought out a small pillbox.

“Ecstasy?” Ty asked.

“No,” Heather said. “These are special pills.”

“What do they do?” Jordan asked. He seemed genuinely concerned. This was his father’s house, after all. He didn’t like the idea of hard drugs used here.

“You take them and after about 12 hours you… change.”

“Uh, like how?” Ty asked scratching his head. “You become an asshole or something?”

“No,” Heather said as she pursed her lips. “You turn into the opposite sex.”

The guys all started laughing. Heather and Jodi turned and looked at each other knowingly.

“Wait, are you serious?” Mark asked.

“Yes,” Heather replied. “You would become girls and Jodi and I would become boys.”

“That’s impossible,” Jordan said.

“Why don’t you try it and see?” Jodi offered.

“Ok, so we would become chicks and you would become dudes after 12 hours?” Mark asked through laughter. “Is it permanent? Or do we change back?”

“You change back to your old self after about 48 hours or so,” Heather explained.

Ty stepped up, grabbed the pill box, opened it, and popped one of them into his mouth.

“Ty! What the hell are you doing?” Mark exclaimed.

“Relax, they’re bluffing!”

Heather and Jodi looked at each other with their mouths open in awe.

“Jodi and I will go next,” Heather said.

The two girls swallowed one pill each and then handed the box to Randy. He took one and passed it Jordan. He shrugged and popped it in his mouth. Mark was the last to go and took a bit of time before committing.

“This is nonsense, right? No way it’s possible. I mean, I like my dick,” he said.

“Just do it,” Ty urged him on. 

Mark sighed, picked up the last pill from the box and looked at it. It almost seemed to sparkle for a moment. Then, without thinking, he opened his mouth, placed it on his tongue, and swallowed it.

“Woo-hoo!” Ty yelled out.

Mark smiled. He knew it was just a joke and nothing would really happen. He was just playing along with a game. It was just for fun, he told himself. A fantasy.

Everyone settled into their respective rooms. Jordan took the master bedroom, Mark the one next to it, and Ty and Randy bunked up in the guest house right next door. Heather and Jodi got the downstairs bedroom with access to the pool.

After some drinks and a hamburger cookout the group hiked up to watch the sunset over the ocean. Then there were more drinks and a game of Cards Against Humanity. The frivolity lasted into the early morning hours, until finally one-by-one they crashed out…

***

Mark woke up with a funny sensation. He usually had a raging hard-on in the morning but something felt different. He reached down under his boxers to scratch his penis and balls but was shocked to discover they weren’t there.

“What the fuck!” he said as he sat up.

He felt his chest flop forward. The sudden movement was actually a little painful.

He looked down and a pair of large tits were stretching his t-shirt. Then he pulled down his boxers and saw his privates were gone! A vagina was there instead.

No one else heard him yell out that expletive. They were all still fast asleep. As got up out of bed Mark wondered if they had been affected the same way.

He went over to the mirror in the bathroom and took his t-shirt and boxers off to examine himself. He had the same hair color, but it was shoulder length now. He was completely smooth except for a little heart carved out of his pubic hair above his vagina.

Squeezing his tits, he admired himself for a moment. It was if he was in this body but not completely in control of it.

“Holy fucking shit!” a young woman’s voice cried out from the master bedroom.

“Jordan! Is that you?” Mark asked.

“Uh, I don’t think so, dude! I’m not sure who I am right now.”

Mark walked into Jordan’s room. Before him was a gorgeous brunette with big tits.

“Buddy, I hate to say it, but you look hot,” Mark said.

“Holy shit, you do too. Those pills really worked!”

Just then Ty and Randy ran over from the guest house.

“What the hell, bros!” Ty shouted.

“This is bonkers!” Randy said.

They were all girls now so their guy-like speech sounded a bit funny to one other. All of their physical features had been feminized, but they retained their hair and eye colors. As Mark had thought, it was them, but not really them.

The four gathered in the living room and stared at their new and different bodies. They were still wearing their sleeping clothes and started to take them off. Sexual tension started to fill the air.

“Check out my tits!” Ty squealed in somewhat girlish delight while bouncing up and down, which surprised him a little. He let that feeling slip away and accepted his new body.

“They’re massive,” said Randy. “Can I squeeze them?”

“Hell yeah, bro!”

Girl Randy went over to girl Ty and felt up his breasts. 

“This is really weird,” Mark said while watching Ty and Randy play with each other.

“So Heather and Jodi weren’t lying,” Jordan said.

Some male voices could be heard coming from the downstairs bedroom. Two guys emerged. One had short blonde hair and a bit of facial scruff. The other had shaggy brown hair and piercing green eyes.

“Heather? Jodi?” Mark asked.

“Hi guys, or should I say, hi girls?” the blonde male said. “Oh, and I’m Heather. But we really should choose new names for our new selves. At least until the pill wears off.”

“This is nuts,” Mark said.

“You sound like Mark,” the brown haired male said. “I’m Jodi, but I think I’ll go by Billy.”

“And I’ll be Ray,” Heather said.

Had the girls planned this all along? Mark thought. Why are they so sure of themselves in their new bodies? So much so they’re already dishing out suggestions to give ourselves new names?

“This is confusing,” Jordan said. “But for the sake of the game I’ll go by Jordana.

Well he fell in line rather quickly.

“Randy and I will be Anna and Elsa,” Ty said with a giggle. “Because Frozen sucks.”

I can already tell Ty and Randy are lost in this. And why is my own mind starting to feel all fuzzy? Wait, what is happening? Why am I about to say--

“Oh wow, we’re doing this. Ok, I’ll be Kellie!” Mark declared.

“Good, it’s settled,” Heather, now Ray, said. “And don’t worry, the effects do wear off after a couple of days or so. I do have to ask, however, why are Anna and Elsa naked?”

Ty, now Anna, giggled some more. Randy, now Elsa, shrugged her shoulders.

“They’re admiring their boobs,” Jordan, now Jordana said.

“Again: This is nuts,” Mark, now Kellie said. 

“Well, you don’t have nuts anymore,” Anna said through more giggles. “Why am I so giddy?”

Why indeed? This fuzziness is getting worse. I feel like my mind is slipping into...

“Say, you were pretty protective of that backpack,” Elsa said looking over at Ray.

“Well, there are some fun items in it.”

“Besides those pills? Let’s see them,” Elsa said.

“Alrighty.”

Jodi, now Billy, was scratching his face.

“You ok, Jodi -- I mean, Billy?” Kellie asked.

“I don’t know how you guys do it,” he said. “Facial hair is disgusting! I’m going to take a bath and shave. I feel gross all over.”

Billy went back into the downstairs bedroom and into the bathroom. This left Ray standing there with the four newly transformed girls staring at him.

“I’ll get the backpack… After I shave too,” he said. “I agree with Billy: Guys are foul haha. Can I use the upstairs bath?”

“Sure,” Jordana said.

After Ray grabbed his personal bag from the downstairs bedroom and went upstairs to shave the four girls convened outside on the patio by the pool.

“I’m feeling all funny,” Elsa said. “Like I want to touch myself.”

“I just think we’re all a bit excited being in these new bodies. And it’s strange we’re all smooth, right? Except for these weird hearts above our pussies right? Wouldn’t we need to shave, too?” Jordana asked.

“Don’t look at me. I’m not sure what the rules are for magic gender-transformation pills are,” Kellie said.

Anna and Elsa began to admire one another’s breasts again. Jordana stared at them for awhile until Kellie got her attention.

“Let’s have a look at that backpack.”

“Good idea,” Jordana agreed.

The two girls went into the downstairs bedroom. Ray was in the bathroom with the tub water running. Jordana and Kellie looked around and found the backpack hidden away in the closet. Kellie grabbed it and the two of them went back out into the great room. 

Anna and Elsa were on the couch kissing each other and fingering their pussies.

“You’re girls now for like ten minutes and you’re already fucking each other?” Jordana said with mock disgust.

Kellie unzipped the backpack and dumped the contents onto the dining room table.

“Oh wow,” she said.

Jordana turned her attention from Anna and Elsa back to Kellie as she examined the items laid out in front of her.

“What are they?” Jordana asked.

“Come over and see.”

Jordana stood beside Kellie and looked down at several metal chastity devices, two strap-ons and other sex toys.

“Who brings stuff like this?” Kellie asked aloud.

“I need some coffee,” Jordana said.

“Good idea. I’m also suddenly craving greek yogurt.”

Jordana and Kellie enjoyed coffee,had a light breakfast, and watched with curiousity as Anna and Elsa continued to have sex on the couch. After some time, Billy emerged from the downstairs bathroom freshly shaved and showered.

“Wowsy, I feel so much better,” he said.

“You care to explain these items?” Kellie asked him while pointing at the dining room table.

“Oh shit! You weren’t supposed to look at that. It was a surprise,” he said.

Ray appeared at the top of the stairs and looked down at the scene. He could see Anna and Elsa were going at it on the couch. Elsa’s head was buried in Anna’s vagina. Meanwhile, Billy was arguing with Jordana and Kellie at the dining room table. Then he realized what they were going on about in such a heated way: The sex toys!

He rushed down the stairs and jumped into the conversation.

“Hey guys, you shouldn’t have gone through our stuff!” Ray said.

“This stuff?” Jordana said while holding up one of the chastity devices. “What were you going to do with them? Put them on in us in our sleep after we turned back into guys? Make us play another game?”

“They’re just for fun,” Billy said.

Anna and Elsa walked over naked hand-in-hand.

“Are those chastity devices?” Elsa asked. “They are! We should put them on Ray and Billy now that they have cocks!” 

“That’s a good idea, Elsa!” Anna happily agreed.

“Now wait-a-second,” Ray protested.

Ray and Billy didn’t realize just yet how strong there were now that they had turned into guys. Anna and Elsa didn’t comprehend how much weaker they were as girls. So when Elsa grabbed one of the chastity devices and lunged at Ray, the scuffle was rougher than expected.

Something sparked in Jordana. She joined in to try and subdue Ray. Anna came up from behind and jumped on his back. Kellie stood and watched.

“Help us!” Jordana yelled out.

“Fuck it,” Kellie said and then joined in.

Billy saw how crazy things were getting and ran outside.

The four girls finally got Ray held down and spread his legs apart. Elsa fumbled with the metal chastity device.

“It won’t open,” she said.

Anna grabbed the keys from the table and passed them to Elsa.

“One of these should work!”

Elsa tried several of the keys until one fit and then she unlocked the device. She looked down at Ray with a mischievous smile.

“You thought this was going to be some sick twisted perverted weekend, didn’t you? Thought you’d fuck one of us, right? Well not with your cock in chastity you won’t!”

“No!” Ray screamed. “Let me go!”

“Stay still,” Elsa commanded.

The three other girls kept her immobilized while Elsa placed the device on. She pulled Ray’s freshly shaved balls through the steel ring and then his penis. She adjusted his genitals until it was in a good position for the tube to go over his shaft. Once properly in place, the locking mechanism was set, the key turned, and then released. He was now chastised. 

“You bitches!” Ray yelled as he sat up.

“I think it makes sense,” Elsa said. “Girls lord over guys and make them dance around like idiots to try and get the pussy. Now that you are a guy you will be denied the chance of entering one yourself.”

Ray stood up and looked down at his locked cock and balls.

“Take it off!”

“I imagine once the pill wears off it will just fall off when you get your vagina back. Until then: Enjoy being a cuck beta boy,” Elsa said.

Kellie didn’t want to laugh but found herself doing so. Her mind felt even fuzzier. It was as if reason was leaving her and she was giving into primal urges. 

“Let’s find Billy and lock him up too,” Kellie said.

The four girls nodded to each other. It’s like that had become a pack of she-wolves. Ray looked on in horror as they went outside. They were all practically naked with no regard to modesty or safety.

Ray, a new male now locked in chastity, looked over at the keys and toys strewn about everywhere. 

“Looking for this?” Elsa said through the doorway while holding up a key. “You’re not getting out. Once we find Billy we’re going to have some fun with you.”

Elsa turned and ran back to rejoin the hunt. Ray considered bolting out the front door but he didn’t have the keys to the SUV. And even if he got away how would he get the device off? How would he explain it? His head was starting to feel a bit fuzzy too. The desire to fuck a woman was starting to take over. But why? He liked guys. What was this pill doing to him?

After a few minutes the four girls paraded Billy back in.

“We have your friend,” Elsa said with a devilish smile. “Time to lock his little cock up too.”

Billy seemed completely defeated and accepted his fate willingly. His failure to escape had broken him. After his penis and testicles were securely fastened in steel chastity the girls led him and Ray to sit on the couch. Then they collected all of the items and took account.

Elsa, who seemed to have taken the role of the leader, held up a strap-on.

“I always wondered what this would feel like,” she said.

Anna had two red ball gags in hand.

“These do indeed look like fun. Should we secure them?” she asked.

“No, please don’t!” Ray protested.

Billy did nothing to fight back. In fact, he opened his mouth to accept the ball gagh. Ray struggled but eventually was forced to give in. Elsa took some pink rope that was in the backpack and tied their hands behind their backs.

“Now look at you two,” she said. “Thought you were going to have your fun and play games this weekend, huh? Thought you might fuck us real good and have something on us, I bet. Well, not thinking that anymore, are you?”

Drool, not words, was coming out of their mouths.

“You might as well watch as we have a good time,” she said.

The four girls were now completely into each other. They got together on the floor in front of Ray and Billy and started kissing and fingering. Kellie licked her own pussy juice off of Jordana’s fingers after she stuck them deep inside. Anna tongued Elsa’s asshole. Debauchery took over.

Elsa put on a strap-on and lubed it up with a bottle from the backpack -- the bag was filled with endless delights, apparently. Anna got on all fours and put her ass up in the air. Elsa guided the 10-inch attachment down to her pussy and slid it in slowly.

Kellie and Jordana shifted their attention to the action and watched as Elsa began to pound the young co-ed. They admired Anna’s tits as they swung back-and-forth. It wasn’t enough, however. They needed to be a part of it. So they crawled over and started kissing Anna’s body. Jordana got underneath, grabbed a tittie, and sucked her nipple.

After that is was a mix-and-match of cunnilingus, vaginal and anal intercourse, and other forms of stimulation. And while Ray and Billy watched helplessly, their locked cocks leaked precum from the excitement. The changes to their bodies had also had an effect on their minds. Arousal was heightened. They wanted so badly to be let loose and mount the girls, but knew they couldn’t. There had to be other ways to achieve pleasure.

Elsa finally slowed down, pulled out of Anna, and walked over to Ray and Billy. Her strap-on was flopping about, covered in pussy juice. She grabbed their locked cocks with either hand at the same time and squeezed. The changes to her body and mind had made her more dominant.

“How does that feel you little beta cucks?”

They moaned in agony.

“Oh, you nasty boys are leaking too! So disgusting. Maybe you should taste yourselves? No?”

She went behind the couch and ungagged them, but left their arms bound. Then she came back around, put the tip of her index finger from each hand onto the tip of the tubes for their locked penises and collected some precum.

“Now, do you want to taste yourself?” she asked them. “Do not speak! Nod yes or no.”

They both nodded yes. 

“Open your mouths and stick out your tongues.”

They complied. Rather than put their own precum into their respective mouths, Elsa decided to let them taste each other. Billy gladly accepted Ray’s juices, but Ray fought back. Elsa closed his nose shut and forced his mouth open. She had to stick the precum on his tongue quickly -- she didn’t want to get bit!

Then she forced the shaft of her strap-on into Ray’s mouth.

“You want to taste that pussy, don’t you?”

Kellie, Jordana and Anna were standing behind Elsa now. The four girls had complete control of the two chastised boys.

“Hmmmm,” Elsa mused. “What can we do with these two? If we can’t use their cocks…”

“Let us eat out your pussies,” Billy offered up.

“Now that’s a smart, good boy,” she said. “I imagine you could go for hours. But, if you’re going to have the pleasure of pleasuring me, you might have to accept a good pegging.”

“Wait, no!” Ray exclaimed.

“Oh sweetie, it’s happening,” Elsa said with a smirk.

Billy and Ray were led into the downstairs bedroom. Anna and Elsa lay back on the bed with their legs spread. Billy and Ray were made to crawl up to their vaginas and start licking, with Billy on Anna, and Ray on Elsa. 

Kellie and Jordana put on strap-ons and got behind the two oral pleasers. Elsa nodded in approval and the two girls filled the guys’ asses with their rubber shafts. Kellie on Billy and Jordana on Ray. The males moaned as they lapped and tongued. They tried to buck back against the strap-ons penetrating their asses, but the girls pounded harder, pushing the boys faces deeper into the two wet, hot vaginas.

Over the next two days this cycle repeated: Fucking, teasing, eating, sleeping, waking up. Ray and Billy became slaves of desire and never achieved a full orgasm. They would be forever denied...

*** 

The next morning Mark woke up. He reached down under the blanket and felt his cock and balls -- they were back. He breathed a sigh of relief. 

Heather opened her eyes and immediately knew she was back in her old body. She rolled over on her side and felt a hard object against her skin. It was the steel chastity device! She grabbed and tossed it with disgust, not caring where it landed.

It was rather quiet as the group had coffee and orange juice, and ate what breakfast food was left. Then they packed their clothes and stuff up in silence. 

No one was sure what to do with all of the sex toys. Jordan decided he had to collect them all otherwise he’d have to answer questions from his father. He put them into the black backpack and carried the bag with him outside to the SUV.

They all got in the SUV one-by-one. Mark made sure the back gate was secure and came around front. After he hopped in the driver’s seat he turned on the ignition. He then looked up back at the house, the place where everything had happened.

He was about to turn and say something to the group when he thought better of it. Probably best if things were left unsaid. At least for the moment. 

Jordan sat in the front passenger seat with the backpack between his feet. Mark looked down at it and then focused his attention on driving.

The SUV backed up, did a three-point turn, and headed down the hill towards the coastal highway below.
