Hand it over before you start jogging back home

"Zere it is," you say as you pull out the Chip. Hundred credits. You look over at Danielle who is impatiently holding out a hand with a smile on her face.

"I hope you won't make me regret zis," you say as you give her the Chip.

"Hard to regret what you can't remember," Danielle said with a smile as she put the Chip in her sports bra.

"You made me not aware of the change? Not cool sis," you say in a more normal accent.

"I just wanted to see if that awareness modifier worked," Danielle said with the wave of her arm as she began walking in a brisk pace, starting the return trip back home. "nobody but me remembers it now. But suffice to say I didn't change anything I haven't done myself."

"A hundred bucks, fifty bucks effectively. That's a big change, sis," you say with a pout.

"It's alright Joni. You may not remember what was changed, but it was for the greater good," Danielle say with her infectious smile plastered on her face. "When we get back home I promise to turn you back into how I remember you: My perverted big brother."

"Ugh, fine," you say as you flash a hungry smile at a cute guy walking past. "And if you do it right, I promise to write down what I remember of your past life, put it in a letter so you can read if whenever you want to."

"That sounds like a fun little gift," Danielle said over her shoulder before plugging in some earbuds. She was done with the conversation so you shrugged and did the same yourself.

As you return home, the two of you shower and change clothes. Danielle had actually let you run past you the last hundred meters so you got dibs on the showers first. If she'd spent the time taking a few chips, you didn't know and you honestly didn't care, since they were mostly dangerous to the people who can give them away.

As you walked into the hallway, you remembered. Mom's not home tonight! You turned around at the sound of a door opening. A smile widened on your face.

You were moaning as Daddy filled you with his cock. Step-dad, to be precise. You'd sucked his cock as a guy before. You and your sister were terrible perverts, and your mom, if she knew, had never confronted you with it.

Danielle had heard the sound of you kissing and sucking on Daddy's cock and joined you. Now she was teasing you by sucking on your toes while Daddy was stuffing his step-daughter's pussy with his breeder cock. You'd loved Daddy's cock as a boy as well, but having a womb for Daddy to fill was much more... fulfilling.

It didn't take long before you'd climaxed a few times. Daddy of course, wasn't even close, and started fucking Danielle. He likes to use your hungry mouth to dry off some of your sister's gushing pussy juices, and you don't mind sucking him clean. In fact, you think he was more eager than ever now that you were both girls, and it really made you happy deep inside to see him so eager.

After bringing your sister to multiple climaxes, Daddy made the two of you sit next to each other for a shared facial. As he finished you began licking his seed off each other's faces and he patted you on your heads for a few moments before going to the bathroom to clean up. Now it would be another week until mom was gone and he'd put his mask back on. Daddy was very caring, and the two of you were very jealous that mom got him most nights for herself.

"Phew, what a ride," Danielle said as you got ready to go to sleep, fixing her hair so it wouldn't get frazzled during the night. You shared bedroom and were close as peas in a pod.

"You're telling me, sis," you say as you gesture to your crotch. "Having a pussy is awesome! Did you see how hard Daddy got tonight?"

"I know," Danielle said with a wide smile. "I've not been fucked that hard in months!"

You nod, smile and giggle as she spoke, then put up a hand. "Let me guess, did you make Daddy more horny for us?"

"... A little, maybe?" She said with a mischievous grin on her face. "I'll write it down in a note for you tomorrow, so you can read it if you want to. but personally, I think it's fun to have a secret on you. The same way you have one on me."

"Well... I guess my secret is worth over five hundred compared to your being worth a hundred, but I get what you're saying," you said as you yawned. "Oof, I'm spent," you say as you walked over to your bed. "I got some ideas for who we could try to use the chips on, but... I and too tired to think about it now."

"Sweet dreams, sis," Danielle said as she went to her own Queen sized bed, reminiscing the day.

As Joni went to shower, Danielle silently went to their bedroom and pulled out four hundred dollar worth of Chips. She walked into the kitchen and found Joni's homely but average dad and step dad, preparing a basic spagetti and tomato sauce dinner. His back was turned against Danielle as she quietly put the chips down on a slightly anonymous spot on the kitchen counter. She then stepped away and began making noise, looking through cupboards and drawers and huffing in frustration.

"What's the matter?" Dad asked over his shoulder.

"Uh, Joni's bought some poker chips case," Danielle said in a pouty tone. "I brought some with me earlier, but I can't find them."

Dad glanced around the kitchen and quickly noticed the chips next to the spice canisters. He walked over and picked them up. "You mean these?"

"Oh my God yes, those," Danielle said in a beaming tone and bounced over with a hand outreached. As dad dropped the chips, Daddy saw them land in Danielle's hands. Now he was built like a train, a foot taller, barely fitting in his white buttoned shirt. He was balding but he'd shaved most of it off anyway, and he gave Danielle a look that told her mom was not home tonight.

"Uh, Joni's still in the shower," Danielle said as she giggled at the attention. Two hundred dollars of effective change, altering physique and relationships without anyone but her being wise about it... Joni was going to have some fun tonight.
