Yes

I thought for a moment, took out my phone, and amended the "bow before me" trance rule to read:

"Whenever I or Emma say the phrase 'bow before me', the person or people it is said to will go into a trance like state. Whatever orders or instructions I or Emma give them in that state will be followed when they wake. The phrase will affect neither me, nor Emma"

And with that I said "bow before me" to everyone in the room.

Daria, Eric, and Megan, all went into a trance, while Emma looked around trying to figure out what just happened. I explained the rules of the trance as she listened carefully.

After taking it all in, Emma said, "we really are gods, aren't we.... nothing matters anymore."

And after a brief pause, added, "I'm horny again. Megan, you will be my personal assistant, it is all you want to be, and you all you want in life is to do absolutely anything I want or ask for. In your eyes I can do no wrong."

"Eric," I said, "you are going to be ashamed, but also very turned on by the prospect of becoming a transwoman. Every time you taste cock or cum you will be come a little bit more feminine and like it, but you will keep your cock."

Turning to his sister, I said, "Daria, you will gladly help your brother become more feminine."

With that done, I said "wake up."

Daria woke first, and immediately sat up from her bed while rubbing her pussy, she looked around the room confused as to what was happening while thinking about what she just had experienced. Eric's eyes slowly opened as he looked around in a daze.

Megan, on the other hand, was already up and picking up Emma's clothes. If it bothered her that there were 4 naked people in the room covered in various amount of sex fluids, she didn't show it.

"Ok, Megan, Eric, Daria, you guys go shower, Emma and I need to talk." I said.

Megan looked to Emma, who nodded.

As they walked out, you looked back at your sister and said, "holy shit that was hot...."

"yeah..." Emma said, as her hand went back down to play with her pussy "oooh, wow, i'm sensitive now..."

"I mean... I can fix that" I said, thinking.

"fix what?" Emma said, "refractory periods?"

"Honestly, I think literally anything to be honest... check this out."

I pulled out my phone and opened the app and added a new rule: "I and my sister Emma, have a refractory period of no longer than 10 seconds after sex, are both in peak physical condition and stay that way regardless of what we consume or do, do not age, cannot be killed, will heal from any wound no matter how grievous in 10 seconds, and all pain is dialled down by a factor of 1000x, and maxes out at 5% of our pain tolerance. My dick will be 12 inches long when hard, and can get soft or hard on command." I clicked enter and looked up.

Emma had slimmed down considerably and looked like an olympic athlete with curves. I looked down at myself to see a stunning 6 pack and arms of a greek god.

"Holy shit..." Emma said as she looked at my crotch, where a foot long veiny monster laid.

"Em, I think its time we put old habits behind us" I said, standing up and turning towards my sister.

"Josh, you're a total freak." she said, but her eyes never left my dick.

I reached down and cupped her perfect breast and kneaded it as she raised my dick to her lips.

"Oh my god..." Emma said as she closed her mouth around it, taking it deep into her throat. She was getting used to the girth quickly.

She let me fuck her face for a minute while Daria walked in.

"Good to know you're forcing your sister to fuck you too, not just us." Daria said.

I grinned and said "puppetmaster mode. You'll follow any order my sister gives you. Puppetmaster mode over."

Daria's face went pale as Emma grinned at me and took my dick out of her mouth to make an ahegao face over it, "Mmmmm, I could use a new tongue on my pussy, Daria" Emma said without ever taking her eyes off me.

Daria was still standing there in shock. She didn't move, but she had stopped breathing for a moment. Then Emma pulled away from my cock, "thats an order, not a request." Daria came back to life with a start.

"Ok," she started saying while blinking furiously and falling to her knees in front of Emma, "I've never gone down on another girl before..."

Emma leaned close to whisper something in her ear before kissing her deeply, "its ok sweety, i'm sure we'll work this out just fine... "

Daria tentatively leaned toward Emma's pussy with her tongue out, but Emma just grabbed the back of her head and pulled her in, "get in there girl" she said as she pulled daria's head down.

Daria was taken aback a little bit, but nonetheless she took a deep breath through her nose and began licking my sister's cunt.

I groaned, as I was about to reach the edge and Emma looked up at me smiling, at that moment her eyes rolled back in her skull as she must have had an orgasm and I let loose into her mouth.

Daria pulled away for air for a second to see Emma cumming like crazy while trying to catch everything I gave her.

Emma patted Daria on the head, letting her get up, and she also stood up, just as Eric and and Megan came back in. With a big grin, Emma walked right up to Eric, grabbed a hold of his dick and gave him a deep kiss, pushing all of my cum into his mouth. The effect, once more, was immediate, Emma's hand was immediately full of Eric's cum as he orgasmed at the taste of semen. Giggling, she brought it up to her mouth for a taste, before putting it in Eric's mouth as he was recovering, causing him to have yet another orgasm.

"Oh my god!" Daria shouted, "stop it! Let him breath for a second!"

I smiled and said, "Ok, you guys take a breather, I think Emma and I need to go talk to our parents."
