My legendary class is Husband Of Deathwill Sisters?!

"Thanks for helping me with Olivia," Alex said to his blonde-haired girl, the dullahan momma, sounding grateful for her presence.

Sara was everyone's big sister. And as she used to have a good relationship with Olivia, she took the lead by inviting her for shopping and other stuff.

Both took care of Celia, going with her to kindergarten and doing other things together. They bonded pretty well in those few days.

Sara smiled, holding Alex's hands tightly, "I like her. And you two were so cute together that I will ensure she likes our big family. Celia also didn't know how she missed Olivia, so those were enjoyable days for us."

Everyone bonded as much as they could. However, the responsibilities still took over the majority of their time. It was rare for Alex's family to be together.

His birthday party was a good excuse to drop everything.

Only a battle against the common enemy would call everyone to one place or other peculiar events that required attention.

Today, Alex and Sara would spend time together with each other. And as it was a night, even a moron would know what these two had their eyes on._.

However, as Alex was finally about to learn about Sara's desires and fetishes, he was somewhat nervous.

He swore to see what it was and give her an honest answer.

It didn't mean that Alex wouldn't be nervous, however. He spoke about many things on his way toward his bedroom in the Deathwill Castle, hiding his feelings.

Sara easily could see through her beloved, getting shyer with passing seconds. And when they were about to step into Alex's bedroom, the couple stopped.

An awkward silence ensued.

Alex knew today's night took more toil on Sara's heart, so he didn't let his nervousness stop him. He took the knob, opening the doors to his private place.

In that bed, Alex had lost his virginity. Of course, it was a game world, so his real body didn't taste the beauty yet.

Still, it was a precious day for both him and Sara.

Alex invited his girl in, not letting her hand go.

But as Sara finally gathered all courage she needed, she let his hand go, telling him to take a seat on the bed, "Just wait, okay?"

Alex nodded, gulping down.

He sat on his bed with his casual clothes on, gawking at the floor with indescribable feelings building within him. To have proper knowledge about fetishes, Alex did some research beforehand.

He stumbled upon some disgusting stuff that some girls liked. On the back of his head, he always had those fetishes, fearful that Sara might have one of them.

Of course, he had already heard some of Sara's candid thoughts.

She called him Master, but was that just it?

At last, Alex heard steps. Sara had returned from the bathroom, her steps echoing loudly in Alex's mind.

"Master…" Sara called her husband in such a peculiar way. She sounded weak, soft, and embarrassed, yet that was exactly what Sara wanted.

Since Erin called Alex in such a way, he wasn't feeling that odd. It still sounded different, for the dullahan momma said those words, no one else!

Alex lifted his eyes, immediately dilating those as Sara stood naked before him, holding collar and pen in her hands. That was not all, though. Behind her, Alex saw a horse tail swaying left and right as she stood awkwardly.

He knew dullahans owned horses, and their skills were related to these, but for a dullahan herself to be a horse?

It was surely something no dullahan would ever share with anyone, let alone the dullahan with royal blood.

Seeing his confusion and shock, Sara parted her lips, speaking from the bottom of her heart, "Sara wants Master to mark her… Write his name, his nicknames, and her nicknames on her body… Sara wants Master to put a collar on her neck and turn her into his pet…"

While saying those words, Sara's horse tail swayed even faster. It wasn't a real tail, of course. It was something she plugged her ass with, moving it through her muscles here.

And as she was proficient in it, Alex could tell that Sara had often stuffed her asshole with items like these.

‘At least it's not coprophilia or something worse…' Alex inwardly sighed, relieved like never before.

He then stood up, facing Sara, who spoke in the third person, "Pen."

Sara slowly lifted her left hand, passing a black pen to her beloved. That pen had a special ink that would make things surely enjoyable for her and maybe her master.

Alex used his left hand to slightly lift Sara's right tit, then used his other hand to write down his name on her skin. The pen slightly scratched Sara's flesh, making odd sounds.

It was a smooth and quick process. Black ink also stayed and contrasted well with Sara's snow skin.

After finishing his first task, Alex looked up, only to flinch. His dullahan momma had her lips parted, drooling, her eyes glazed in affection and lust. She blushed so much that she steamed, and her breath was as if fog.

Her horse tail swayed so much from the happiness that it was odd how Sara managed to stay still on her two legs.

No, her legs were growing weaker as well.

"Sara… thanks her master…" she whispered in a lovely voice, panting heavily while doing her best to form a smile.

Alex wanted to become Master like he had done numerous times in his sexual adventures with Schnee. However, Sara's fetishes were unique, and her reactions didn't help him either.

But he somewhat understood her.

She let it all out to him. Even a little acceptance would make Sara's heart jump with happiness.

And as Alex didn't comment but followed her wishes, Sara was just too elated.

He couldn't become that Master, but he easily could continue.

"Alex's momma now," he chuckled, writing such a nickname on Sara's breast. It was still the same breast, for her chest was ample, enough to store many words.
