As Asta gets Mimosa ready for her imprisonment, she begins to confess to the false charges. But a last minute thought in her mind changes that which leads to a loving relationship with the black bull.

Things were hazy for the young Mimosa Vermillion. She was naked as a newborn baby, her large D-cup sized breasts heaving as she breathed while sweat covered her entire body, while her long wavy auburn hair was a wild mess while her yellow eyes were half-closed from exhaustion.

Her memory had just caught up on the events that led to her situation as she was naked inside the large carriage that took her to her final destination.

She remembered everything.

One minute she was looking for ways to help improve her magic, the next she ends up finding one of the couriers she was assigned to protect dead from poisoning. To make matters worse, the murder weapon was in her room and she was promptly arrested for murder.

The trial didn't go in her favour and she was pronounced guilty.

The worst part was that slimeball Salim gloated to her that he had framed her as revenge against Yuno! How petty was that asshole?!

Luckily, fate had been kind to her as Asta and Yami came in to rescue her, letting Asta have first claims to her bubbly ass.

Now here she was. Naked and about to have the final preparations made to her for the sentence. If there was one thing she was happy about, it was the fact that Asta was going to be her master and not Salim.

She would've actually committed murder if she was sold to that slimeball.

And now we reach the present.

Naked and now escorted to the Black Bull's hideout, about to get dressed for her new life as a prisoner and a breeding slave.

Asta's new breeding slave. Mimosa's heart fluttered just thinking about it, the gooey creampie in her asshole still warm after such a long trip, her buttcheeks still smarting with light teasing pain from when he'd spanked her like a disrespectful schoolgirl in front of that crowd. How could a fate that had seemed like such a nightmare with Salim be turned into such a heavenly fantasy?

She did not know, but she felt she should have known better by now than to question it when Asta did the impossible.

A neatly folded orange leather outfit was dropped beside her on the bench, a pair of black thigh-high high heel boots on the floor of the carriage. Naked save for her black leather slave collar, Mimosa looked up to find Asta imperiously looking down on her, his glorious muscular arms folded over his perfectly sculpted chest. He'd never looked so… authoritative.

"Get dressed, inmate," he commanded.

Mimosa bashfully blushed, having never had a man watching her as she dressed herself, but Asta's frown when she hesitated reminded the noblewoman that she hardly had a choice. She was no longer an aristocrat or a magic knight. She was a convicted criminal and murderer, and Asta was her warden.

The princess stood up and unfolded her new garment, recognizing it as an anti-magic jumpsuit meant to further suppress her powers even after her grimoire had been burned right in front of her when she'd been convicted. Mimosa stepped into the skintight prison uniform, zipping up the orange leather catsuit over her smooth bulging breasts. She then grabbed each of her new boots and one by one stepped into both of them, the glossy black leather hugging her muscularly toned calves tight as the high heels threw off her balance too much to ever attempt to run away from her incarceration.

"Turn around, Inmate 44645," Asta ordered, his voice stirring and cold. "Hands behind your head."

Mimosa stepped around to face the carriage's wall and did just that, her arms rising to plant her palms behind her orange mane. Asta approached her rear, the rattling of chains audible as he roughly grabbed the princess's arms and yanked them down behind her back, the young knight yelping as she was slapped in handcuffs once more, the shackles tightening until their cold iron pinched into the royal lady's wrists. As Asta knelt to clamp sturdy metal leg irons around Mimosa's boots, the gorgeous woman couldn't help flashing back to the day she'd first been arrested, the fear and humiliation that had gushed through her as she'd been marched away to jail.

However could she have predicted that a different man putting her in chains would cause that same terror to be transformed into arousing anticipation?

Asta stood up after locking the leg irons tight, unzipping the flap of the prison uniform covering Mimosa's privates and her delectable ass, her inmate brand seared into her perfectly round buttcheeks. He then firmly grabbed the royal felon's handcuffed arms with one hand and reached up to unbuckle her ballgag, tearing the rubber sphere from her mouth for the first time in days as the beautiful lady gasped for breath.

"Sorry about this, Mimosa," Asta said. "Procedure is procedure. There was nothing I could do back at Briar Haven but what I did."

"I know, Asta," the arrested knight of the Golden Dawn assured him, a deep blush covering her cheeks. "Truthfully, I am grateful that my first time was with you rather than Count Hapshass."

"Heh, glad I was able to make it a little less horrible," Asta replied with a cocky swagger. "Don't worry. Once we get that creep and prove he framed you, we can get you out of these chains and you'll never have to do that with me again."

Mimosa's eyebrows shot up, the princess grateful she was facing away from her jailer so he could not see her sudden panic. Not for catching Salim, no, he'd literally confessed all the details on his plot to her. She could tell Asta everything and he would bring the full force of the Black Bulls and the Golden Dawn to bear to pull at the crime's threads until the truth unraveled. She'd be safe in Asta's care and now that she was officially his property, he wouldn't lay a hand on her until she was exonerated.

He wouldn't lay a hand on her if he thought she was innocent. And she wanted him to lay many hands on her. Hands, and other body parts.

"So can you give me any details on murder scene?" Asta inquired, completely oblivious to the life-altering decision his captive had just come to.

In one instant, she would've confessed to the murder, then and there. And she would be enslaved to Asta, making her dreams come true.

But the words wouldn't come out.

She tried but no luck.

What was preventing her from admitting to the crime?

"I...Can I tell you later? It's been a long day for me." She said, with a tight smile.

Luckily Asta seemed to understand.

"Eh, sure. I'll get the details later. In the meantime...' He then opened the door to her cell and shoved her inside. 'I suggest you get comfortable." He said as he recuffed her so that the wrists were in front of her then locked the door.

Mimosa than sat on the cot, grabbing the pillow and buried her face into it. Letting out a sigh, she screamed into it.

"AARRRRRGH! WHAT'S WRONG WITH YOU?! YOU'RE ONE CHANCE TO HAVE ASTA AND YOU BLEW IT! COME ON!" she yelled.

Why didn't she confess to the crime?!

It was then a voice came into her brain.

"Are you sure that is how you want to confess your feeling to him?"

Mimosa's eyes widened at the thought and started the rebuttal.

"Well yeah. If I say I'm innocent, then I'll lose this one chance."

"Oh please, you really want to be with that bull this way? At the cost of your reputation?!"

"Well..."

Mimosa couldn't answer that. Was ruining her rep really worth just getting together with Asta?

"OK, fine! But what else am I supposed to do?!"

"Just confess straight away. The guy's denser than a barrel of fish jelly! You need to be blunt."

Mimosa just blushed heavily at the thought.

"I CAN'T DO THAT!"

"Look, just wait for him, then just tell him how you feel. Sometimes that's all that it takes. A leap of faith."

Mimosa was silent. That voice had a point. Maybe she should just take a chance.

A few hours later, Mimosa was laying on her cot, thinking how to go about this, when she heard the cell doors open.

"Hey Mimosa. Time for your little punishment." Asta said, holding a length of rope, collar and an orange ballgag.

Standing up, she held out her wrists and allowed the cuffs to be taken off. She then turned around and let Asta wrap the rope above and below her large, D-cup sized chest.

"You know, I really didn't want to do this." He said as he made a knot behind her back.

"I know. But it's your job." She said with a smile, letting a cute gasp out as her arms were pinned behind her back horizontally. Asta then fastened the rope around them, pinning them there.

Turning her around, she then went to her knees just as Asta lowered his pants to show his erect cock to her.

Mimosa gulped but knew what to do next, closing her eyes as she engulfed the sausage with her dainty mouth, sucking as she did.

Asta sighed in bliss as Mimosa continued to suck him off. As much as he wanted to marry Sister Lily, even he would be stupid enough to try and dismiss Mimosa giving him a blowjob.

Hell, lately any feelings for the nun were starting to diminish during the time he spent with Mimosa.

Maybe Yuno had a point in saying that him and Lily was never going to happen.

Plus, Mimosa was always there for him despite being in different squad.

He gasped as he felt her sucking harder as she soon began to deepthroat him, lathering her tongue all over it and covering it in saliva. It wasn't long until he felt something build up from within his cock and he felt it blast cum into her mouth, some spilling into her jumpsuit.

"Wow. That was amazing." Asta breathed out.

"I know." She said, licking the cum off her face.

The two then stood there in awkward silence before Asta decided to speak.

"So...umm...' He said, blushing as he looked away. 'What was it you were going to tell me?"

Mimosa blushed as she remembered.

"Oh! Um...' She fidgeted nervously in her bonds. 'Well...I...I..." He face turned red.

Concerned, Asta stepped forward, and lifted her chin so their eyes met.

"What's wrong?" He asked.

Mimosa then realised something. Time to make a leap of faith.

She just leaned forward and captured Asta's lips with hers.

Asta's eyes widened at the action, frozen in shock. But whether it was Liebe telling him to go deeper or his own instinct, he deepened the kiss, bringing her closer as he wrapped his arms around her waist, one even squeezing and groping her butt.

They then broke apart, a string of saliva connecting them. Faces flushed at the action.

"So...Is that what you wanted to tell me?" He asked.

"Honestly, it was something else. But yeah. I..I love you." She confessed, all the weight flying off her chest.

"So...uh...how long?" Asta had to ask.

"Ummm...since the dungeon mission. I...never had the chance to confess to you. Then the war against the elves and Midnight Sun and now...well, you know what happened." She admitted.

"Wow. That long. So...what now?" Asta asked.

Mimosa tilted her head cutely as she asked.

"What do you mean?" She asked.

"Well, unless I turn you into a concubine or whatever, I'm not sure we'll be allowed to be together." He said, rubbing his head.

"Well, we can always keep it a secret. Until then, I'm all yours." She said playfully.

"OK.' His eyes then widened. 'Oh right!" He then took out the collar he took and placed it around her neck, signifying he now owns her.

"Well, how do you want to do this?" Mimosa asked.

"Well, I am feeling frisky. But what do you want to do?" he asked.

Mimosa smiled as she bent over into a right angle, shaking her lovely ass to him.

"You know what to do big boy." She said.

Asta grinned as he unzipped the area leading to her clit and ass and lined himself with her asshole, but not before stuffing the ballgag into her mouth.

And with one thrust, he entered the tight asshole of one Mimosa Vermillion.

Mimosa let out a huge groan as drool soon covered her gag, especially when Asta started to pump and thrust into her.

Soon Asta grabbed one of her boobs and another hand smacked her ass as he continued to thrust like an angry bull, no pun intended.

It was a miracle that they didn't fall over but Mimosa kept her balance as the chains on her leg irons shook.

Asta increased his speed as he continued to pump into her at high speed that he hadn't kept track of how long it had been. Soon Asta felt his cock tighten, ready to unleash his load into her, so he just increased the speed he was at.

Soon.

"AAARRRRGGHH!" In typical Asta fashion, he unleashed his load into Mimosa's ass like a fire hose. Mimosa even moaned in ecstasy as she did.

Soon it was finished as Asta took out his cock and the two flopped onto the bed. Asta had enough energy to take the gag out of her mouth as she panted from europhia.

"That was..." Asta began as they flopped onto the bed.

"Yeah..." Mimosa finished.

They laughed a bit and shared a gentle kiss.

"You know, I will find out the truth right?" Asta said in a knowing tone.

"I know. But until then...I just want you all to myself." Mimosa said with a smile.

The two chuckled as they shared one last kiss before Asta left the cell.

Both smiled at the new arrangement they now had.
