"Look at these stupid pants Ron just threw at me."

Marjorie St. John looked at the jeans her 19-year-old fraternal twin sister Lauren was holding up. "Men's pants?" She could tell by the pockets.

The slim, bespectacled brown-haired girl chuckled. "Yeah, he said they were women's. I wonder if all younger brothers are stupid or just ours."

Marj rolled her eyes. "All of them, but he's special." The fit, tanned blonde got to her feet. "Well, let's see you in 'em."

"Yeah? They do look like they'd fit, don't they? Okay..." She pulled the jeans up over her tights. "Yeah, perfect fit." As she fastened the top button, she gasped. "What the fuck?"

"What?"

"I..." Lauren blinked and reached down to the prominent bulge between her legs. "I got a cock!"

"Fuck off!"

"Look!" Lauren unfastened the top button to show her sister but the weight of the male appendage disappeared. She pulled the pants midway down to her thighs, revealing her obviously female genitals surrounded by trimmed brown pubic hair.

"That's yer pussy, Laur...hey, weren't you wearing tights?"

"My Lulu tights!? No, fuck that, where's my dick? I felt it." She pulled the pants back up and re-fastened them. "Yeah, there it is." She cupped the bulge.

Marj came close. "That *does* look like a dick...can I...?" Lauren moved her hand and her sister reached forward. "Holy shit! How is this happening?"

They quickly figured out the trick to unfasten all the buttons of the fly but the top one and Lauren's new penis slipped out the hole, 8 inches long and thick. "Ho...lee...shit..." Marj breathed. "That's magnificent...I kinda wanna suck it."

Lauren looked down at her blonde sister kneeling before her. "Do it."

"But...that's kinda gay..."

"That's obviously a man's cock...suck it, bitch...dare ya."

Marj closed her eyes and took the thick phallus into her mouth.

Ron was watching his mother on TV again, railing at the trans people and their supporters. The slightly chubby brown-haired 18-year-old nodded along to her talking points: these groomers and their lack of family values were contributing to the degradation of society.

His bedroom door burst open, revealing his older sisters holding the pants he had given to Lauren earlier. "Hey! I could'a been...y'know..."

Marj looked at his TV. "...whacking off to Mom?"

"What?! No..." Ron's mother was attractive in an older, made-up, real estate mogul kind of way, with big brown hair and luxury clothing, but he didn't find her sexy.

Lauren shook the pants. "Whatever...where'd you get these?"

"Mom left 'em on my bed before she left this morning."

"And you didn't put 'em on?"

"They're women's pants...I'm not a crossdresser. No idea what Mom was thinking."

The girls looked at each other.

"What?"

"Put 'em on," Lauren told him.

"No!"

The girls exchanged another quick glance before jumping at him.

"No! Get offa me!" But Ron knew that it was no use...his older sisters would sometimes gang up on him and once again he had no choice but to do what they said. Marj, always the stronger sister with her light weightlifting regimen, pushed his arms back and sat on his chest while Lauren pulled off his jeans, thankfully not taking his boxers for the ride. He could only see his blonde sister's C-cups above him, so closed his eyes so that he wouldn't accidentally get hard. He felt his other sister pull the new pants up his legs, then sighed and lifted his butt to assist. He learned long ago to just do what they wanted and their terrorizing would be over that much quicker. As the top button of the jeans fastened, he frowned at a strange sensation between his legs. "Uh, what's happening?"

Marj turned her head back to Lauren. "Well?"

"Holy shit! It's totally gone."

Ron frowned. "What? What's gone?"

Then the pants were unfastened and pulled down his legs. Marj got off of his chest and he found that he was completely naked from the waist down. "Lauren! What the fuck?! Gimme back my underwear!"

Marj looked at his penis, which was confusingly half-hard despite the emasculating treatment. "Looks like he could be almost your size, Laur."

Lauren got a glimpse before her brother covered up and rolled off the bed. "Nowhere near yours, though, Marj...you win."

"Hell yeah I do." The twins high-fived each other as they strode out of their brother's room, slamming his door closed as they went.

Ron peeked over the side of his bed. "What the fuck?"

---

Lauren pulled her mouth off of her sister's thick 9-inch cock. "Ugh, my jaw hurts...you think this thing would fit down here?" She rubbed at her prominent clitoris.

"You sure?" Marj stroked her length as it poked out through the gap in the button fly of the obviously magical jeans.

"Yeah...I'm so fucking wet...c'mon..." Lauren turned away from her sister and presented her bony ass to her.

Marj swiped the head of her thick phallus between her sister's wet folds and pushed. She had some trouble at first, but the leftover spit and Lauren's natural lubrication helped. The bulbous tip slipped inside.

"Oh fuuuck...go slow..." Lauren moaned.

Marj angled the head of her cock in a circular motion just inside the entrance to her sister's pussy, making the slim girl moan. Soon, her insides loosened just enough and Marj pushed into her a little more.

"Fuck...cumming...nng! Nhg!" Lauren gasped.

"Mmm..." Marj took advantage of her sister's orgasm to push more of her length inside. They had been giving each other blowjobs but the feeling of her new cock inside her sister's hot pussy was even better! After Lauren's orgasm subsided, Marj pulled back and was soon able to stroke most of her thick length into her sister.

"Jeezus..." Lauren moaned as she pushed back at her sister's cock. "Never had one so big before...oh shit, gonna cum again..." She bent forward to allow her sister deeper access to her depths.

"Uhh...me too...can I cum inside, Laur? I don't wanna pull out."

"Oh God! Yeah...yeah, do it, I'm on the pill...OH FUUUCK!"

Feeling her sister cum on her cock, Marj thrust into her hard, feeling all the pleasure in her body focus itself on the tip of her cock before the sensation moved down her shaft, drew her cum up from her balls, and then rushed back up. "Oh yeeaahh! Cumming in you, Laur! Oh, it's so good! Uh! Uhh!"

"Shiiit..." Lauren moaned as she felt her sister's thick cock inseminating her wanton body, extending her own orgasm.

When their orgasms were done, Marj commented, "It's so intense, cumming as a guy, but it's all focused on the cock, y'know? A guy wouldn't be able to take cumming like a woman, don't you think?"

"Are you saying...?"

"I think I am."

"Hmm...gimme the pants...I wanna do something first."

Ron sat in his desk chair masturbating to porn on his laptop. It was lost on him that the content he was getting off to was about a brother and sister...he didn't care...cock in pussy was all that mattered, and the chick was hot.

Suddenly, his door burst open and his sisters were in his room again, quickly closing the door behind them.

"Fuck! Get out! I really am whacking off this time!"

Lauren stepped forward. "Shh! We've seen it...get onto the bed again, little brother."

He noticed that both his sisters weren't wearing bottoms or underwear, but it only distracted him for a moment. "Laur, please..."

"Now! And keep the pants off."

He did so, covering his unit with his hands. His normally talkative blonde sister kept her mouth shut and went back to sitting on his chest, though she faced his feet this time. He felt them pulling those pants up his legs again and he lifted his hips, resigned to whatever crazy shit they had planned.

Lauren had trouble getting the waistband of the pants done up with her brother's still-hard cock in the way, but once she had the top button fastened, the problematic phallus disappeared. She slipped her finger into the fly hole and rubbed at the lips of her brother's new vagina.

"What...? What is that?!" he cried out.

"Shut him up," Lauren told her sister, and Marj moved her bare ass back, right onto his face.

"Mmphk!" He moved his hands up to dislodge her, but Marj captured his arms under her strong lower legs, causing her crotch to press harder into his face. Having trouble breathing, he jostled his head until his nose was free, but this caused his sister's pussy to center right onto his mouth.

"Mmp!" Marj grunted.

During all of this, Lauren hadn't stopped playing with her brother's new pussy. She couldn't see it but it felt much like her own, and she was very familiar with that. She could feel it lubricating from her attentions. Smiling, she moved her hand up to her sister's mouth. Marj allowed those fingers to dip between her lips, and when they came back out they were covered in sperm from the load Lauren had blown into her sister's mouth after they fucked earlier. Lauren slipped those cum-covered digits through the button fly and into her brother's vulnerable pussy.

"Unghf! Uhgdd!" Ron struggled under Marj's weight as he felt a new sensation that he couldn't even describe. He had tried putting a finger into his ass once but it felt gay so he never tried it again. This was similar but way more intense!

Marj's brother thrashed below her, causing his mouth to reverberate along her already wet pussy. She grunted again, the combination of that along with the perverted thing they were doing to him causing her to have a little orgasm. She made sure not to swallow Lauren's load, though, and allowed her sister to extract another couple fingerfulls of incestuous sperm from her mouth before those digits were slipped back inside their brother's temporary pussy.

Ron felt something rising up from deep inside him, a sensation that he'd never felt before. He instinctually thrust his hips up into his sister Lauren's delving fingers, groaning in disappointment as she took them out but moaning in pleasure again as they went back in, though he was unaware that each time this happened, more of her dangerous sperm was being pushed into his defenseless female reproductive system. Reflexively, his tongue delved into his blonde sister's pussy and she gasped. Finally, that strange feeling swelled within him like a balloon and then burst. He cried out into Marj's pussy as his first female orgasm blew through his body. His pelvis thrust up into his other sister's fingers as she brought him off, the angle dripping some of her sperm right up against the opening to his uterus as it spasmed open in pleasure. "NGHH! OHGDD! GDD!"

Marj gulped the rest of the sperm down and cried out as she came on her brother's face. "Uhh! Fuuuck..." She ground her pussy into his mouth, cutting off his oxygen.

"GHH! HHH!" Ron continued to cry out in orgasm before he collapsed.

Marj, breathing heavily from her own release, got off of her brother. "See? Told'ya he couldn't take it...out like a light. Oh..." She turned to see her sister furiously frigging her own clit.

"Fuck...fuuck...FUUCK!" Lauren came hard on her fingers and then collapsed next to her unconscious brother. Marj cuddled up to him on the other side. "Crap, Marj...when he wakes up he's gonna tell Mom what we did."

"Hmm...maybe we offer to fuck him if he keeps his mouth shut?"

"Eww...well, maybe. We'll have to wait here until he wakes up so he doesn't call her before we do that." Lauren put her glasses on his side table, lay her head on her brother's chest, and closed her eyes. She heard her sister's breathing slow on the other side of the young man, and soon all three of them were asleep.

Except they had left the jeans fastened around Ron's hips, keeping his reproductive organs female as Lauren's sperm soaked into his depths...
