Corrin's POV

"Ahh Hoshido." I sighed walking towards the castle "It's good to be back."

I wasted no time walking into the castle ground and looking for someone I knew.

"Sakura." I smiled walking over to her and Hana.

"Huh?" the little princess turned and looked at me "Corrin?"

"In the flesh." I smiled hugging her, shoving her face into my chest like Camilla used to do to me.

"Umm…Big Sis." She mumbled between my breasts "I'm…suffocating!"

"Sorry." I smiled letting her go "Is it just you two around, where's Hinoka?"

"She went out into the countryside for something." Sakura explained.

"What a shame I was hoping to see her." I pouted.

"I'm sure she'll be back in a few days." Sakura said.

A few days…I don't want to wait a few days.

"Haaa…" I sighed "That's a shame, I suppose she'll miss out for now."

"Miss out, what do you mean?" Sakura asked.

"I'll tell you later, let's go eat lunch first." I said.

"Okay." Sakura smiled "I've wanted to spend time with you."

"Hana why don't you join us as well." I smiled.

"Oh, okay." The swordswoman smiled.

The three of us went to the kitchen and chatted, neither Hana or Sakura seemed willing to ask about my body, but both seemed interested.

"Are you both going to avoid it or ask?" I smiled at them "It's okay girls."

"Umm…well, why are you all busty?" Hana asked.

"You used to be pretty modest." Sakura blushed "But the way your dressed and how you look…"

"I've changed a bit." I smirked looking at my breasts "All thanks to this."

I placed the two bottles on the table.

"Now why don't you girls drink it, I'm sure you'll love it."

"I don't know." Sakura said.

"Won't you do it, for me." I smiled.

"Well…okay." She shivered in her chair.

"If Lady Sakura is doing it than I will too!" Hana said drinking her bottle "I'll go first to show you what'll happen Lady Sakura-OH!"

Hana began to change before our eyes, I heard Sakura gasp as Hana's chest puffed up into D-cups, her face matured a little and her crotch notably bulged outward.

"Oh…oh wow." Hana moaned "That felt really good~"

"Hana you look…" Sakura stuttered.

"Stunning." I told the girl "So what about you Sakura?"

"Oh Lady Sakura you have to try this." Hana moaned rubbing her crotch through her clothes "It feels so good."

"O-Okay." Sakura mumbled.

My younger sister nervously opened her bottle of potion, cautiously bringing it to her lips and slowly drinking it down. Sakura let out a groan as her body started to grow, her hips widened and her dress rose up a bit as her butt got larger, the chest area on her dress began to stretch as the seams popped her breasts grew bigger and bigger. Sakura moaned again as her lips plumped up and got full while her cock grew in.

"Ha…ha…" Sakura moaned "This is…wow."

"My you look gorgeous Sakura." I said reaching out to cup one of her huge F-cup breasts.

"These look so nice." Hana hugged Sakura, reaching her hand up to rub her masters breasts.

"You both look great." I smiled "Sakura I haven't seen anyone get that close to me in size, you look so sexy."

"Hmph" Hana pouted "what about me."

"You're cute too Hana." I smiled.

"Big Sis." Sakura squirmed, her now ripe melons rubbing together "I feel really warm."

I looked down and saw Sakura's dick twitching to an erection.

"There's no need to worry." I smiled and walked close to her "you're just sexual aroused, you're going to be feeling like this a lot more, part of the potion."

"I…UMM!" Sakura moaned "OH!"

Sakura grabbed Hana and made her turn over, throwing the girl's butt in the air and suddenly inserting herself in.

"HAAA SAKURA!" the girl squealed.

"I'm sorry!" Sakura said thrusting into the girl "But I'm just so turned on!"

"It's okay!" Hana moaned as her body was rocked back and forth "I'll always be around for you, no matter what you need, especially this!"

I stood behind Sakura as she railed Hana, I reached out and started bouncing the Princess' breasts around.

"Sakura you've got such big soft breasts." I whispered to her.

"That feels nice." Sakura moaned as I played with her breasts while she fucked Hana.

"As it should." I said flicking her nipples around and rubbing my dick against her ass "You've become a beautiful woman."

"Sis…" she blushed as I pulled her chin up and started kissing her.

As Sakura and I shared a sisterly kiss Hana kept moaning from the rough pounding Sakura was giving her.

"I can't hold on!" Hana moaned "I'M CUMMING!"

Hana moaned louder as she orgasmed, her whole body shaking and her cock spasming and spurting out cum.

"OHHH!" Sakura screeched as she came inside of her Retainer.

"You're not gonna leave me hung out to dry are you?" I asked Sakura.

"Oh no of course not!" she gasped "I-I'll take good care of you I promise!"

Sakura dropped to her knees before me, hefted up her big breasts and started shaking them over my cock, her soft chest bounced around, giving me a great titfuck.

"Sakura that feels wonderful." I smiled.

"This…this is nice." Sakura smiled moving her chest "They feel so bouncy and soft."

"I take it your liking those big breasts of yours." I smiled rubbing my own large chest.

Mine are so big I can barely see her down there.

"Yes." Sakura nodded "I do like them."

"Good." I said.

Sakura kept giving me more pleasure. I looked to the side and saw Hana was on her back stroking her cock and shoving her fingers into her pussy.

"Oh…Oh Sakura!" I gasped "Get ready I'm about to…OHHHH!"

I started cumming, blasting out ropes of cum which splattered into Sakura's face and on her breasts. She quickly freed me from her breasts and han laid back, rubbing the cum all over her breasts.

"Feels so nice." She mumbled.
