Step 6: Confront dad. Step 7: Acts like he can't remember being mentioned the possibilty of puppy adoption. Step 8: Get disrespected by bratty little brother, bragging about the landslide of presents he got and how he's dad's favorite. Step 9: Stew in the unfairness of it all.

Step 10: Pretend to get over it. Step 11: Roll eyes at little brat digging through wrapping paper of his new bike's box, head first, with puppy like squeals. Step 12: Notice he got a decently sexy butt. Would look ok naked. Rocking a butt plug with tail. Couple tattoos maybe ?

Step 13: Annoying squeals could be almost endearing if they were barks. Step 14: Bratty mouth would be put to much better use wrapped around my toes. (or cock) Step 15: Dad favoritism more acceptable if I were an only child. Step 16 :Easier to apologise than ask permission.

Step 16 : Little brother scared of needles. Way too squeamish to do his own injections. Pestering me every friday til I agree do it for him while he looks the other way. Never says thank you. Step 17 : Look up online sellers of blackmarket DIY human domestication kits.

Step 19 : Next time brat comes for his injection. Distract him with a video game. Doesn't notice his syringe a little fuller than usual. Nothing nasty, just a little cocktail of dog hormones to change arousal patterns, increase skin sensitivity, and send him in regular heat.

A healthy mix of hypnotics to increase suggestibility, gradually reduce IQ, and to enhance natural obedience tendencies. Empathogens to power up love and devotion. (In layman's terms : slow release M*dma). And just for this first time : Knockout roofies to make him pass out.

Step 20: While little brat out, prepare another syringe. Quite a bit longer and nastier looking than the intramuscular one. Long acting desensitizing nerve agent. Step 21: Pull down little brat's pants. Step 22: Stick syringe in the base of his t-dick. Step 23: Push !

Step 23-bis : cackle like an evil witch. (super important). Step 24 : While I'm at it, inject him in nipples with opposite agent, long term sensitivity increase. When you think about it, nipple teasing, almost like doggy belly rubs. Step 25: Unlock brat's phone with his face.

Step 26: Flash said phone with special domestication root-kit. Giving me complete remote control access. Set up subliminal messaging to be blasted every time he uses it. Doggy prog 101. "I need to be called a good dog." "My sister's cock is yummy, I want it in my mouth."

(Start simple, dog-rome was not built in a day.) Step 27: Little brother still passed out, look in satisfaction at his drooling boypussy as his first doggy heat hits his unconcious body. Step 28: Stick under his nose a pair of my nastiest cum encrusted panties.

Step 29: Lubricate vibrator and gently push it up his ass. (ignore sleepy whimpers) Step 30: Turn up vibrations, play with my new dog's nipples, let him breathe in and out my cum smell as I get him closer and closer to a sleeping orgasm. (Squeals mean you're doing it right).

Step 31: Make him cum twice, learn his body's honest reaction pattern. Start conditioning him to associate pleasure with my touch, smell, and bodily fluids. Step 32: Pull up brat's pants. (SUPER IMPORTANT) Step 33: Wait for brat to start stirring. (Grab a good book.)

Step 34: Act loving. Tell little brat he passed out when he saw the needle. That it's okay big sis will always be there for him. He can rest for a while. (he should be reeling from the Md*ma shot, and feel overwhelmed by love at the moment.) Step 35: give nice warm hug.

(Not an equal's hug. Little brat's head squished against my chest. My hand firmly in his hair. Gentle non verbal cooing. Too early for dog hormones to have effect but Never miss an opportunity to establish superiority and dominance.) Step 36: Now we wait for preliminary results.

Step 37: Days pass, little bro feels a little weird but doesn't notice anything until suddenly hit one evening by his first heat. Step 38: Get an alert on phone monitor of him frenetically scrolling through porn. Step 39: Hear through shared wall rising whimpers of frustration.

Step 40: Satisfied sigh. Imagine how awful it must be to be so horny with an unexplainably insensitive T-dick ? Step 41: Wait for whimpers to turn to sobs of despair. Step 42: Gently open little brat's room door, ask with fake concern : "Hey bro... everything all right ?"

Step 43: Usual reaction would be to yell at me to get out of his "effing" room. But suggestibility drugs + a week of subliminal suggestions that I know best have started to erode his bratty exterior self. "I... I can't cum!" he cries in touching despair. Step 44: "Lemme help"

Step 45: little brat still in control, tries to cover himself as I get in. "N...no you can't, you're my sister...." Step 46: Accept no modesty. Pull back the sheets, and get in bed with him. "Ssh. You're in pain. I won't let you suffer when I can help. Relax. Be a good dog."

Step 47: Pull him close, grab his cute little boy nipples between my fingers. He tries to pull away but I give them both a good squeeze. Wave of unexpected ecstasy hits the pleasure center of his brain. Makes him relax in my arms. Step 48: tease, tickle, and squish. Repeat.

Step 49: "Why... why does this feel so good ?" Little bro struggling in my arms as I get him so close to the orgasm he's been craving for hours of feverish humping. Step 50: "Because big sis knows best. Say it with me and I'll make you feel all better. Big sis knows best."

Step 51: "bbb.... bbbb... big sis knows best ! BIG SIS KNOWS BESSSST !" Crush little bro's nipples between thumbs and forefinger while he arches his back, tongue out, drooling like a good dog, head nestled in the crook of my arm. Step 52 : "Always come to me when you need help."

(Little bro fully mind blown from first nipple orgasm of his life. Looks at me like I'm a mixture of a witch, angel and alien. Very satisfying.) Step 53: Don't let him recover, get him in spanking position over my knees. Lube up my fingers and start playing with his cute butt.

Step 54: Fingerbang him to spectacular anal orgasm. Muffle his screams with an old sweaty gym tee shirt of mine. (musk conditionning!) Only release him when the iron grasp of his first heat finally relaxes around his mind and he curls up in my lap with a satisfied doggy sigh.

/// TBC sometime today.

Step 55: Gently guide brat's head between my head. Let him feel the shape of my ROCK hard cock against his cheek. Let him take a deep breath of my arousal. Let him associate it with relief and safety. (I'm so horny right now I could explode, but now is not the time for that.)

Step 56: Guide little brother to bathroom. He should be meek and obedient for a while after cumming his brains out. Step 57: Gently undress him. Don't listen to his weak protests. Promise it's okay, I'm in charge, he's safe with me. Step 57: Give him a warm relaxing shower.

(take off my shirt but nothing more. Getting him used to his new normal little by little : humans are dressed, dogs can be naked.) Step 58: Scrub him all over. Promise I won't tell dad. No one has to know, and that big sis will always be there for him. (such a promising boy.)

Step 59: Slow shampoo to make him realize how good and relaxing head scrubbing feels. Soon have him whining and pushing his head back against my fingers. Joke (lol) and call him my puppy. So relaxed his eyes half close, his tongue lolls out. Looks disappointed when rinsing.

Step 60: As I'm about to let him back into his room, dried and in fresh pjs, he grabs my hand. "C... can I sleep with you tonight ? I'd feel better..." Step 61: Surprise. Didn't expect such good results after a week, even though I got kinda heavy handed with his injection.

Act hesitant (not annoyed, never act annoyed with your puppy he should never feel like a burden.) Pretend I'm doing him a big favor. "Okay but you're sleeping on the floor. My bed is way too small for two." (strategic : keep the possibility of sharing bed as a massive favor)
