God's champion sat across from across from the golden dragon priestess. The day had been a long drawn out process of explaining that, in fact, Felt cannot swear and threaten nobles during important meetings.

"He's the stuck up one!"

"Lady Felt i understand that but his domain supplies a quarter of grain to the Astrea domain"

"Whatever! You wouldn't understand how it's like to grow up in the slums like me, sword saint!"

As she angrily stormed out and left the lone young man alone, Reinhard thought; Ah, she said sword saint instead of reinhard, his divine protection told him that she was angry.. But surely everyone knows swearing is not proper in formal environments… if only he could spend a day or two understanding her more without his knightly responsibilities… "WAIT!" the red head shouted before it took effect

A white smoke engulfed the room accompanied by a young boy's shriek. Felt jumped at the sudden explosion and shriek, and ran as fast as the wind would allow her back to the room where she told off the strongest man in the world.

"Did you kidnap a boy this time you creep!"

A young voice she had not expected to hear responded and her knight was nowhere to be seen

"Uhhhhh i think its temporary but i did wish to spend a day or two"

Felt took her dagger out at the perceived intruder and dashed forward towards the sound but hit air as she found herself moved by space itself 5 feet to the right of the cloud smoke

"Felt-sama! It's me!"

"Huh…"

The cloud dissipated and the… even younger man? Stepped forward in enormous clothes with the most powerful weapon casually laying on the floor.

"How did?..."

"..."

"I apologize Felt-sama, but it appears i'm stuck like this for the next two days, i accidentally triggered a divine protection when i wished to understand you more"

"You wanted to… understand me?"

"Yes Felt-sama"

"Hmph you should say felt-onee san with the way you look" she said as she threw her arms up with a smug look

"Felt-sama was that an order or a joke, I'm… not the best with these things?"

Felt's realization of the situation hit her like the force of a dragon carriage. She would have a shota reinhard all to herself for two whole days!

… but the other realization hit them both, Luginca's sole source of national security was now a little boy.

"I don't think we should tell anyone about this rein-chan!"

Reinhard: "Rein-chan?"

Felt turned into a tomato by how red she was, she never had a younger brother growing up with gramps! She always wanted siblings. Sadly Rom wasn't enough of a looker to score anything so she wasn't going to let this chance fly by!

Felt: "Yes that was an order, you will call me Onee-san and i will call you Rein-chan!"

Reinhard: "Y-Yes Onee-san"

Felt: "You said you wanted to understand what it's like to be me?"

"Yes Lady Fel… Onee-san"

"Hmmmm in that case we can go through my daily routine but it's getting late so i have my evening bath now!" she said with a big grin pointing a thumbs up towards God's chosen shota

Reinhard: "i will take my bath after dinner like always Felt onee-san"

Felt: "siblings always bathe together! So we will be taking one together!"

"Felt onee-san, neither of us had siblings so how do we know this for sure?"

"Shut it rein-chan"

"A knight and his lady cant bathe together, it's scandalous"

"Are you my knight or younger brother? I can't tell." "hmph" Felt grabbed his arm and rushed to the baths. All staff have long been ejected from Felt's wing of the estate after she was prone to outburst, leaving the sword saint to handle the menial task of servants.

As soon as they burst through the bath's doors Felt had the biggest grin and blush and went to undress. Rein was extremely nervous, if word got out that the sword saint was bathing with his lady then his family would be ruined more than it already is.

Felt "How the hell did your clothes revert back to a normal size for you!?"

Reinhard: "hm? Oh my divine protection of fitting and tailoring"

"Just take it off already and get in the bath!"

"I really think this is a bad idea what if one of our staff sees us Felt onee-san"

"Just use one of your divine protections are something you idiot"

His lady's words came first before everything else including his own desires so he obliged and wore a towel around his waist, too shy to actually show himself fully

Felt was already sitting by a faucet with an extra stool she turned around with a blush and pat the seat

"Come one rein-chan, let your 2 day big sis wash your back!" with her usual smug look and a grin

Reinhards face was as red as his own hair as he walked to the stool and faced away from Felt

so she could wash his back

"Hmm you have so much tension mr. sword saint, don't worry i'll wash it away!"

Felt who was in the nude scooted up to the shota Reinhard touching their torsos as she massaged his shoulders dripping with water.

"Rein chan why are your shoulders so stiff?"

"Killing monsters does that to someone's shoulders"

"Hmmmm? What monsters have you killed?

"I don't want to talk about"

Felt scooted up closer, squishing her body against his back and rested her head on the blessed shota's tense shoulder.

She whispered into his ear, "and why is that"

"If people knew the monsters i have killed they would come to it that i am a monster"

"You're not a monster, Rein your just a boy" she bought her hands around the front and held him

She massaged his shoulders and gently gilded her hands over his thin arms.

"Is the tension gone now, Rein?"

Reinhard felt water under his eyes the last time he was hugged was…

"I think so"

"Do you still want me to hold you like this Rein-chan"

"I think so"

"I'll indulge my little bro all i want today!"

They rested against each other near the faucets and Felt's hands fell into his lap as she dozed off but she jolted as she felt something she wasn't expecting. Reinhard jolted up as well at the sudden contact.

However, as much as the blessed boy would have hoped, fate would not have his dignity saved by the laws of nature which obeyed his will, as soon as he stood up his towel fell to his feet exposing his private area to his own lady.

"Ah Rein-chan! I knew you were a pervert!"

"Lady felt i-i im sorry! I couldn't control it!"

He was fully erect the entire time he was getting massaged by his lady and hid himself with the towel. He felt like dying then and there but as no blade could pierce his skin he had no option but to talk his way out of this.

Felt had a huge blush on, she'd never seen one before and rein was being so cute he was so red. And she made that hard? She wasn't even trying!

"i i-its fine! Rein-chan, a big sister has to be used to this right? Im naked too so it's fine!"

Reinhard just realized that she had been naked the entire time, he was too caught up in her words and massage to realize the wet mass touching his back as her small chest and stomach he was erect without even thinking of his lady's body in any way!

"J-just come back and sit down without the towel and i'll finish washing you and you can wash m-me"

"s-sure onee-san"

He sat back down and couldn't cover himself with his hands. He was simply too big. She went back and scooted the seat up closer to his back so she could wash his back with her whole body

"Your shoulders are tense again, is it because you like this rein chan?"

"It's because you're being really forceful while just washing my back"

Felt came even closer and rested her head on his shoulders once again and looked down and saw how he was lying. He was still covering his even more erect member. Her small hands reached downward to his wrist and attempted to pry his hands off of his waist but the strongest boy in the world's hands would not budge.

"Your big sis is telling you to move your hands"

"Felt-sama i think this is to far"

"Who is that? I don't know a Felt-sama"

"Felt onee-san"

Reinhard obliged and moved his hands uncovering his bigger than average erection to his own lady. He was so red he felt what he believed normal people felt when they were about to faint from embarrassment.

"It looks like it hurts and it's all red, is it okay?"

"i -it's okay onee-san d-don't worry about it"

"Hmmm it's twitching are you sure?"

Felts right hand reached to touch it, her hand moved confidently in the air until it brushed the shaft earning a gasp from reinhard

Felt: "Did it hurt! I'm sorry!

"No no it's just i wasn't expecting it"

"Can I do it again?" felt was blushing like an apple

"I-if you want too"

Felts small chest collided with his wet back and she reached with both hands gliding them through his arms weaving around and taking a hold of his member, he was easily bigger than two felts hands"

"Mmmmh Felt onee-san that's…" Reinhard never experienced this before and his whole body flushed red as blood was flowing even more to his shaft. She started gauging a reaction when she moved her hands, finding lightly rubbing the back of his cock was the best way to get more of a reaction.

"Does that feel good rein-chan?" she asked whispering in his ear

"Yyes!"

She took one hand off his shaft to hold his face and turned his face back to hers and leaned against his her mouth slightly open she leaned in to kiss him while she rubbed him off.

Reinhard melted into the kiss going limp and melting into his two day big sis's body

"Mmmm onee-saan Im...mmmmmm"

He was cut off with another sloppy kiss, his cock was twitching like crazy, Felt didn't know what this meant but she kissed deeper and rubbed harder

"Felt-onee san!"

Renhard came straight into her hands for a solid 30 seconds as copious amounts of fluid drenched both of her hands as she let go of his face to pump his cock even more from behind.

"What am I supposed to do with all this lil bro?" she had cum dripping out of her hands as she tried to catch it. It smelled just like reinhard and she did enjoy kissing him and tasting his tongue. Maybe this would taste good?

Her fingers dove into her mouth tasting Reinhard's seed as she hummed at the taste

"Felt-onee san don't do that, this was already shameful enough!"

"Mmmm but Rein-chan it tasted so good!" she wanted more but it all went down the drain she couldn't say that out loud though.

Felt got up and walked around to face her little bro head on and leaned in to kiss him even rougher this time with her arms wrapping around his head holding him in place

Reinhard was still delirious from his first of many to come orgasms at the hands of his lady, he was still numbed by the pleasure his two day big sis gave him and is still continuing to give as she separated from the kiss.

She knelt down and put soap on her hands and started rubbing again intent on making her little bro forget his worries. Up and down Up and down for 2 minutes, his cock was cherry red and pulsing from all the pleasurable abuse it was receiving.

He moaned when I kissed him... I wonder if…

She quickly washed all the soap off his cock and opened her mouth, Reinhard was about to reach down to stop her until she gave his cock a wet lick from his balls to the tip as he threw his head back and moaned as she did this.

Bingo! His cock tastes better than his cum and tongue! She continued licking his cock until it was at full mast again. Her eyes widened as she realized his cock was even bigger than when she used her hands! Even though his body was so small his tip reached her eyebrow leaking cum on her forehead as she kissed the bottom of the shaft.

… another idea entered her head, she was only able to pleasure one side of his cock at a time with her tongue if she used her full mou…

She immediately put her two hands at the bottom of his cock and backed off of his cock opening her mouth as wide as she could. She put all of the cock she fit into her mouth and coiled her tongue around his tip. Reinhard let the biggest moan out since she started rubbing his cock and bucked his hips right into her throat. Felt nearly gagged on his shaft as he let out a sizable pre ejaculation into her throat she moaned from the action and her face became red as she realized she couldn't breath with her little bros big cock in her mouth.

She pulled away and gasped for air

"Mmmmmmmmm" they both moaned as she went back down to bobbing her head up and down his enormous cock. While Reinhard was feeling good from Felt sucking his cock, Felt had a sensation appear in her stomach down to her thighs, she was hungry for more of Reinhard. She brought her hands down to her own sacred place and opened her hips to allow for better access as she rubbed herself off while deep throating the sword-saint's cock.

Reinhard grabbed a hold of Felts head and started bucking his hips into her throat intent on cumming inside what dick thought was a standard womb. Felt wouldn't be able to taste what she came for with his dick so far in the back of her throat so she fought his own hands as fingered herself and fucked his cock with her head.

"Onee san! I'm going to finish in your mouth!" Reinhard all but shouted.

Felt started moaning but was muffled by the rod in her mouth causing his cock to vibrate even more he shoved his cock as far into her mouth as it would go and came for another solid minute. Felts mouth and throat was filled entirely by semen so she swallowed and pulled the cock out of her mouth for air; as soon as she did this, however, the young boy continued to come for another few seconds drenching her cheeks, nose and hot mouth with semen.

"Reinhard you taste… amazing!"

"Felt onee san i think weee schoould shtoop nowww." Reinhard could barely speak, he was supposed to be the most powerful man in the world but who knew getting his cocked sucked by the girl he adored would render him melting into the bath.

"Rein-chan you haven't made me feel good! You want to stop after I did all that for you. You idiot!"

Reinhard shot up from his post orgasm daze as his lady, now big sis, criticized him her words came first before anything else including his work!

"What do you want me to do felt sa-... Onee-chan!" he said standing at attention she immediately pushed him onto the floor of the bath.

"I want you Rein-chan!" she shouted with closed fist and eyes as she sat down on the bath's floor with him crawling up to him unconsciously shaking her hips for reinhard to see

"Is this okay rein-chan" she shifted her body so their chest were touching and their faces were an inch away from each other

"felt onee san i…mmph!"

She silenced him with a sloppy kiss and started grinding her hips against his stomach for a solid 2 minutes just holding his younger form and grinding against him felt like heaven to Felt. However the craving empty feeling in her waist remained.

Frustrated, Felt slammed her hips harder against the young boy and slipped with her thighs while straddling him and fell so that his erect rod poked against her stomach.

They both gasped at the sensation with an uneasiness of doing this. If they were to go any further that would be the end of a knight and his princess relationship and the start of a man and a woman like bond.

"Rein-chan i want to"

"I-if its w-what you want i-i wouldn't mind doing it"

Felts face lit up and she was really going to give her first time to her own knight. Her life was really a fairy tale!

Felt: "how do you…" she was so red…

Reinhard "Here"

Reinhard swapped positions with him on top and her back on the bath floor. She had the biggest grin on her face with a single tear. She was so excited to have this experience with him she held her hands out reaching to reins shoulder and brought him in for another sloppy kiss.

"Mmmph"

They pulled away from each other for air and felt nodded

"Rein-chan i think im ready"

Reinhard lined himself and Felt used her wet hands to guide him into her self

"Rein-chan! ah"

Reinhard: "Does it hurt!?"

"No! ah, it feels ~i just got to get ~mm used ! to it"

"Tell me when youre ready for me to move, okay?" he leaned in so his face wasn't an inch away from hers

"~ah"

"Mm"

She stayed liked this for a few more minutes until she gave a nod and kissed him on the cheek

"Im ready… Rein-chan"

Reinhard thrusted his shaft into her earning the loudest moan they had both let out until now.

"Rein-chan you can go faster than ~ah! Thattmm"

Reinhard reached down while her arms were locked around his neck and picked her up and slammed her against the wall with the faucets that were still dipping hot water making everything in the room steamy.

"Ah!" your being really forceful ~ah with some ta~ah ller than you"

He had his head in her neck and gave the side of her neck a bite earning a loud moan from his big sis as she threw her neck back.

"Ah! Rein-Chan!"

"Felt onee-san!"

"Rein-Chan!"

"Rein-chan you're ~ah amazing ~ah ~ahhmmm at this!"

He started thrusting harder instead of faster. Stamina wasn't a problem for his Earth shattering strength he just wanted to hear more cute moans from his big sis and he got them.

"Fuck! Ah~ Reinhard your! Aah~ mmm~" ~aaz! ZING!"

"Rein-chan im! Going to!"

She was silenced with another sloppy rough kiss from the sword saint he wanted to try something new and pulled himself out of her dripping entrance

"What whydya stop you big dicked idiot!"

"Onee-san i wanted to try something different"

"Hm what would that be idiot"

He picked her up and gently put her back on the floor, this time with her stomach facing down he reached her around her and propeed her up on all fours and groped her chest

"Im going to put it back in now, ready?"

"Mhm"

"~ah"

He's so deep! Deep than when he pinned me against the wall it feels like his cock is kissing my womb. If he finishes inside me i might faint like this

"rein -chan ~ahhh"

Mid sentence the shota slapped her petite ass

"Ah~ you can do ~ah do that ~ah more ~ ah ~ ah mmmm if you ~ah WANT ah~"

It was so hard to talk with a 8 inch shota dick inside her pussy! She was so close to cumming before she was getting fucked like an animal in heat on the floor! Now she was crying tears of pleasure trying to reach a climax that seemed far away

"Fuck me!~ AH! Holy shit reinhard!"

Reinhard reached around to grope her small tits once again causing her tongue to fly out of her mouth as she panted like a dog in heat wanting to get knocked up.

"Rein chan im so close" AH~! "Just ah~ faster ! ah~ i-i I LOVE YOU!"

"Me too i-i love you too! Felt onee-san! I'm going to finish inside! Ah~"

"Ah mmm~!" He's going to finish inside me! I'm going to faint and get knocked up! ahhh~

Reinhard grabbed her head and gave her a sloppy kiss as he bucked his cock right into her and came filling her up she came instantly from the result.

They both collapsed on the floor still connected by their waist and making out.

"Reinhard i-i really do love you!"

"Likewise felt-sama i'll love you even more if you let me!" the sword saint was excited at future prospects of baninging his princess

"When you go back to normal size… would you like too?..."

"I would love too onee-san"

They shared a final kiss before actually finishing the long bath.
