Stranger: I was on my way back from the pharmacy, having picked up your medicin like mom asked. I opened up the front door to our house and called out for you. "Hey sis, I got your medicine!". I walked quickly up the stairs, heading in to your room. "hey there missy, how are you feeling?"

You: I look up at you with a sleepy face, i look a bit happier to see you "Hi big bro~ I feel a bit tired... But im happy you are here!"

Stranger: I lean down and kiss your forhead. "got your medicine, you'll be feeling better in no time!" I say and att up some pillows behind your back so you're sitting up comfortably. I reach in to the bag and pill out a bottle, and I pour some on a spoon and hold it in front of your mouth. "open wide little sis"

You: I giggle as i stretch myself forward opening my little mouth for you "aaa~" I drink the medicine with a smile. "I'm gonna get better? I won't feel weak anymore?"

Stranger: I smile at your innocence. "nope! You'll feel as strong as your big brother in no time" I tease. "ok, one more spoon and then we'll wait and see how fast you recover" I smile as I pour some more.

You: i nod believing in you and drink the medicine you hand me obediently "thank you big bro~"

Stranger: "no worries little miss" I smile

You: I smile "I wish i can be as strong as my big brother..." I giggle, leaning into the pillows again, feeling sleepy

Stranger: "you'll feel stronger soon" I smile and brush your hair. I lay down next to you, humming your favorite song quietly.

Stranger: (did you send something?)

Stranger: I sit up on the bed, looking down at you. *she's just too cute* I think as I quietly get out of the bed to grab a drink in the kitchen.

Stranger: Are you still there?

You: (oh sorry i was about to, but got distrated for a moment)

You: i hold onto your body with my little hands until i finally fall asleep

You: (next morning?)

Stranger: (ok)

You: or just later that day, depending on what you prefer)

Stranger: I lay there with my eyes closed, listening to the sounds from outside, yiu still have your hands holding me

You: You notice i seem quite warm, i move a bit in my sleep, holding you tighter

Stranger: I wonder if the fever didn't break yet as I feel your warmth against me. I hug you tight against me, but something feels off. "good morning little little missy" I say quietly and kiss your forhead. "how are you feeling?"

You: I slowly open my eyes, smiling as i see you, i quickly rise up a little and give you big hug, noticeable tighter and more energetic than the usual "A lot better, like you said~ Thanks for staying with me"

Stranger: "seems like your better, stronger even" I smile. "yiu sure you're feeling better?" I ask and out. My hand on your forhead. "you feel warm still. Do you think you need more medicine?"

You: I nod "I think it's working, i should have more to make sure~" I smile

Stranger: "your the cutest" I give your nose a quick kiss before I lean over you, grabbing the bottle and the spoon from the nightstand

You: i giggle, blushing a little "You are the best" once you offer me the spoon i happily drink it "I'm really feeling a lot better~ It tastes very good too"

Stranger: "you look better, alot better" I smile, čand no, you're the best! "I say as I tickle you playfully on the bed.

You: i laugh and giggle as you tickle me, i try to shake you off playfully, you notice i seem more lively and actually quite a bit stronger than usual

Stranger: *she must be feeling great* I think as I laugh, the next time you try to shake me off I'm not really prepare, and feel myself beeing pushed of to the floor, you falling after landing on top of me.

Stranger: I grunt a little as I hot the floor, blushing as I realize what just happened

You: "wah!" I fall on top of you, i seem somehow heavier than i used to as i lie on top of you, giggling "Sorry big bro! Are you okay?"

Stranger: I wrap my arms around you, hugging you tight. "yeah, you just surprised me! And hey, how could I not be okay when I have the prettiest girl in the world as a sister!"

You: I blush and hug you too "I love you big bro, thank you for taking care of me"

Stranger: "I love you too little missy! I guess that medicine helped a bunch huh? You feel stronger already!"

You: I nod my little head "I really do! i feel warm all over, but like a nice kind of warm~" I giggle and lift my little arms up, doing a playful double flex "I'm gonna get strong like bro said!"

Stranger: I gasp as I look up at you, sitting across my stomach flexing. *are those biceps?* I think. *when did she get those?*

You: I tilt my head a little noticing you staring "Is something wrong big bro?" I giggle

Stranger: I gulp, blushing. "ah.. Uhm, no. I just didn't know you had muscles" I say awkwardly. "can I feel them?" I ask

You: i look at my arms, watching the little but nicely defined muscles all over them "Ah... I didn't know either, that's so cool~ And of course you can!" I move the sleeve up to my shoulder, revealing more of it and offering it to you

Stranger: I swallow as I reach my hand up and around your arm, squeezing down, surprised by how hard it actually is. "whoa" I gasp

You: happy to have your attention i try to flex it harder, making grow a little bit more under your hand "Do you like it?"

Stranger: I feel the small ball of muscle grow a little and my eyes widens. "yeah, I.. I do actually. I'm just confused in so. Many ways" I say as I grab your other arm with my free hand

You: i smile as you feel my other arm, which is also nicely muscle too "The medicine must be working right?" I giggle "You should give me some more~ And and... maybe i could do some exercise to get healthier right?"

Stranger: I blush as I realize how much I'm enjoying this. "yeah.. Sure yiu can have some more. And are yiu sure your feeling good enough to exercise?" I try to sit up, but have a hard time with you on top of me.

You: i giggle as i notice you try and stand up,steping away a bit "Yes i do! I feel full of energy, and my head feels a lot better too~"

Stranger: I smile and shake My head as I sit up and reach for the medicin. I pour some. On the spoon and look. Up at you as you're standing in front of me, I spector your arms. "alright supergirl, come down for some medicine"

You: i hop and get closer, happily drinking it "hmm~ I already feel better!"

Stranger: "alright, let's go brush our teeth" I say as I wrap. My arms around your waist and pick you up and head to the bathroom. *she's so heavy all of a sudden *

You: I giggle while you carry me over there "Think ill be able to carry you like that soon?"

Stranger: "absolutely" I laugh as I put you down in front of the sink

Stranger: As I stand behind you, bruising my teeth, I realize you're taller than you were yesterday. I frown as I study you in the mirror. *she looks.. Thicker too. So strange *

You: After im done brushing mine i take a moment to look at you, and notice you staring again, "Is everything okay big bro? Do i look weird?"

Stranger: I blush as you catch me staring. "yeah, fine" I stutter. "and no of course not, you look fantastic" I lean down wrapping my arms around you from behind, nuzzling your neck playfully

You: i smile happily and hug you back "You are so sweet~" I pause a moment looking up at you "Do i seem taller to you?"

Stranger: "yes! Yes you do. I was just thinking about that. Taller and thicker" I say, my arms still wrapped around you. I pick you up and place you on the toilet. "maybe you'll grow this tall" I tease, as I have to bend my head slightly back to look yiu in the eyes from your new position

Stranger: "I'd have to stand on my toes to kiss your forhead " I say, and do just that

You: i smile proudly "I hope i will! That would be great right?" I giggle "What do you mean thicker?"

Stranger: "well.. Your arms are bigger, your shoulders are wider, your thighs.. Well, they're thicker. You look almost grown up" I tease, wrapping you in a hug again

You: I giggle "My clothes feel a little tighter thats true~" I hug you, "then can you teach me how to exercise right?"

Stranger: "sure! Let's go" I say turning around, still holding you. You wrap your strong little legs around me as I walk in to my room where my weights are. I set you down on the ben h up against the wall. "here, try this" i say and hand yiu a dumbell with a 10 on it.

You: i hold it carefully, studying it, then start moving it up and down, my little arm pumping slightly as i do "Like this?"

Stranger: "just like that. How does it feel? Too heavy?"

You: "Hmm.. no, it feels nice" I say as i keep curling it with apparent ease

Stranger: "hm, alright, what about this?" I say and hand you another dumbell

You: i take a look at it and begin curling that one, a bit slower, my muscles straining with effort but slowly picking up the pace

Stranger: "geez.. Look. At your arms!" I gasp "It's like they're growing to compensate for the heavier weight"

Stranger: "does. It feel. Heavy?"

You: I think about it, you notice my arms do seem visibly bigger just from lifting this, in fact my whole body seems to be following, filling out my clothes "I thougt it felt heavy but.. not that much"

Stranger: "this is incredible" I say and sit down on my bed opposite you. Alright, lay down on the bench and try to lift that bar up and down. The bar already has two big plates on it, both reading 15.

Stranger: I watch closely as you lean back and grab the bar

You: i put my little hands, with my not so little arms ready on the bar, i make a cute little grunt and start pushing it up, trying to get a good posture as i lower and lift it again "Am i doing it right?"

Stranger: As you finish a couple reps, I walk over and put on two. More plates. "yes, try to push you shoulder blades together, and arch your back a bit" I say and sit down on. The bed again, watching you. Very surprised how easily your taking to weight lifting

You: i quickly adjust my posture as you told me to, resuming my lifting, keeping up a steady pace, "My clothes feel tighter, think its working?"

Stranger: I gasp as I watch your chest swell from the exercise. "yeah.. Yeah I think it's working"

Stranger: I walk over and put on more plates in the bar, watching you closely, standing right next to your now

You: I keep pushing the weights, my speed barely changing as if you didnt add anything, just my muscles swelling slightly with every rep until they stabilize into a bigger size "How much is this?"

Stranger: "it's, uh, 135lbs" I say, having a hard time. Believing it." Your really strong sis, a real supergirl! "

You: I giggle excitedly "Just like you told me! I gotta grow even stronger big bro! Gonna do it for you~ Give me more!"

Stranger: I smile nervously, blushing slightly as I load up more plates on the bar. Standing over your head, I watch as the bar slowly goes up. And down, and the swelling of your chest catches my attention.

You: you see how my shirt gets pushed up by large growing orbs that definitelly werent there before, a pair of nicely formed and firm breasts, held by my growing pecs, rising slowly with every rep, filling the shirt to its limit

Stranger: I somehow get another pair of plates on, and stand there over you head, staring at your growing body, somewhere in the distance I feel myself drooling as I watch you.

You: I get a few more reps until i hear a rip, my arms having gotten too big for the sleeves "Ah!... big bro it broke!"

Stranger: I gasp as I look down at your ripped sleeve. "whoa, this is incredible" I guide the bar back in to. It's cradle. "how.. How are you feeling?" I walk around, sitting. Down on the bed. "you look.. Wow"

You: I giggle and flex, trying to strike a little pose to please you, you can see my now my body has gotten some good curves, a large chest standing firm on my torso and wide hips with thick strong thighs, my now powerful arms, flexed, every muscle easily visible, im also clearly taller from how small my clothes look on me

Stranger: "ho... How do y-you feel?" I can't help but state, quite shocked at the transformed girl in front of me. "you look incredible"

You: "I feel amazing~ like.. i have so much strength right now! So much energy! Come on you can touch big bro~"
