Demon Lord: Erotic Adventure in Another World

Ryuji woke up to voices in his room, his hands rubbing his eyes with a grimace.

At first he felt someone might be peeking or trying to attack him. However, then he remembered where he was and the voices were familiar.

"So... You're really our teacher? But..." Erika's voice sounded a little confused, her excited tone a little higher pitched than usual. "I mean, you've proved it, but it feels so strange! To think the woman I've been taking part in threesomes with is my teacher, who used to scold me for not finishing assignments on time."

"Now I've seen her urinate herself and squirt while making unholy sounds from her mouth!"

Erika's thoughts seemed to have changed considerably, able to speak such vulgar things so easily. Ryuji remembered when she was too shy to mention the simplest sexual terms.

He felt a sense of loss from his lovely, shy girlfriend, but then the way she spoke vulgar words also made him a little aroused, so he swallowed it and moved on.

"Ah, can you not forget those things, Miss Tendo..." The deep and sexy voice of Yumiko speaking with a passive style of tone made her seem so lovely.

"Erika... We've seen each other's assholes, so why bother being so distant, Yumi? It's not like you're my teacher anymore. You're my rival in love and the only woman apart from Liana that I can stand getting close to Ryuji."

Ryuji crept out of his room, towards the bathroom. His body still smelt like sex, and he wanted to be fresh for today's battle.

He tried his best to avoid making any sound, grabbing only a pair of boxers and a towel before stepping into the warm bathroom. 'It's already prepared, and the water is filled with bubbles and my favourite scent. I love having considerate girlfriends!'

Meanwhile, as he climbed into the water the sound of the two women conversing together continued to enter his enhanced ears.

***

'I am so jealous of Yumi... Last night, their sex was so affectionate and full of passion.' Erika thought while looking at the glossy hair of Yumiko who sat at the table eating an apple, her skin all shiny with a face of complete satisfaction.

"E-Erika... you're a little vulgar, although it's true. Do you have to mention that kind of thing?"

"Oh? Have you forgotten you were the one that basically forced me to sit on Ryuji's face that time at the inn when I still didn't know if I liked him or just wanted to have sex?!"

"That was..."

Yumiko blushed a little, looking away as if hiding something. "I was just curious... and when he did that for you, his thing would swell and get harder, so it became a habit, haha."

Erika's mouth dropped open, and Yumiko couldn't help but begin to laugh seeing her reaction. "Well, don't be strange. You enjoyed your first climax from a man because of my help!"

The two women seemed to start bonding with a strange, slightly hostile atmosphere between them. It was clear the reason why they were getting along so easily, and also why they had a few spats here and there was Ryuji.

"Erika... I suppose we're the same now. Ryuji has shown me pleasure that no other will be able to give us... His cocks can transform into the most advanced shapes and even vibrate, and he has changed me... No, us. For the better, of course, but some things I can't change back, I suppose."

Yumiko's two personalities began to fuse as Ryuji thought, sometimes flirty and serious, other times violent and aggressive while being polite.

"I know, and no matter how much we compete and fight in secret. Let's make a promise not to let it affect Ryuji, Although I want to tear you down from that place and become his Empress and most important woman. I don't want to end up hating each other, so he grows tired of us and runs to another woman..."

Erika's words seemed to resonate with Yumiko; the values of a beastkin woman and a human woman from their world should have violently clashed, but likely due to how much sex and affection she built towards Ryuji during her time without memories allowed her to accept it easier.

"I agree, Erika you're nothing like my student and honestly. I don't want to live as the past me anymore, maybe it sounds wrong and sad to cast away my desire to return or even remember the past. However, with Ryuji, I've been reborn... transformed, and I just want to enjoy my new life, no matter what we face or endure..."

Yumiko's passionate speech seemed to cause Erika's competitive nature to shrink as she accepted the woman and her feelings for Ryuji.

"Me too, and I hope Liana can accept it better, even if she's special and seems a bit weird and innocent. She's a little terrifying sometimes. I think that girl will somehow become our biggest rival, but in a way, we don't realise yet..."

The two girls laughed together, their faces showing no hostility or hate but rather excitement and happiness towards their future and Ryuji's potential growth, which was likely to include more beautiful women in his harem.

"However, we should keep a limit on the number... Even though I was a Beastkin for two decades... Oh god, that means I'm technically over fifty!"

They imagined a future of having children and enjoying their family, and their rivalry and competitive nature were also aimed at wanting to please and become a suitable partner to the man who could satisfy them as no other could. "How about we let him do what he likes, but once there are five women, we start to vet and ensure any other women are worthy of him after that?"

Yumiko smiled towards Erika, nodding her head. "I can accept this, but we will probably have to fight in the shadows, silently and without marking each other, and Ryuji will grow tired of our nagging and whining!"

"Haha, probably! After all, Liana and that elf will likely want to be with him, so we should be wary of old classmates, too... Fuuka's eyes on Ryuji were a little strange. That girl never liked boys before, but each time she met him since coming here, I noticed her watching him as much as I did."

"Fuuka? You mean the police chief's daughter... Ah, she seems the type to sneakily slip into his bed and get knocked up with one session... We should make sure to protect Ryuji's virtue!" Yumiko responded while her ears started to flicker, her tail swaying happily.

"Our beloved has started washing himself in the bath, fufu... I want to go help him, but I'm sore..."

"Sore? Where, I have some ointment." Erika showed a mocking smile. "Or did our lover pound you so hard your insides are swollen?"

"Hey, Miss Tendo! Do not mock your teacher and superior!"

The two argued and teased each other, the sound of Ryuji washing and swimming in the bath entering their ears as they found his actions amusing.

"I can't believe he's swimming in the bath..."

"I know. How cute is my darling?"

'I feel they're arguing, but it's different to normal...'

Ryuji stood at the gate of the arena, beside him a fully armed Yumiko and Erika. What he found interesting is that Yumiko's entire aura changed.

The fierce and deadly warnings he felt from her became hidden. Instead, she was serene and had a quiet aura, wearing a black and red outfit that resembled the shrine maiden outfits from their former world; she hid her gauntlets and greaves well while walking gracefully.

'Wow, she's like a completely different person... My heart is racing.' Ryuji thought, his cheeks a little red as he looked towards his elegant, refined girlfriend, who gave off a calm, peaceful feeling.

Meanwhile, Erika wore black leather armour, with a small cloth mask over her lips, hiding her mouth and nose. She felt closer to an assassin than a warrior, which Ryuji felt was quite mysterious and sexy.

"Shall we go, dears?" Yumiko's voice was sexy and deep, and although not a cat-like purr, her words had a pleasant sound, especially for Ryuji, who loved her voice.

Erika nodded her head, and the three began to walk inside the arena. The sound of the battle in progress was loud; the people inside the stands roared with cheers and screams while some wore masks and roared at the woman inside the ring.

Ryuji ignored them at first, but then he saw the name of the two combatants fighting and stopped "Isn't that two members of Haruki's party? Fuuka and the shield guy?"

Erika looked and nodded her head, and Yumiko showed a strange smile. "Ah, Ryuji, because of Haruki's mistake, he's banned from appearing for two battles; also, he looks in the back. They have the first Princess Anne on their team, so this is practically training for Fuuka and Kenta. It seems Yuki Ito was knocked out already. Look, he is lying over there near the downed knight.'

Ryuji looked towards the arena; the two figures of Fuuka and Kenta were fighting against a knight and another person who seemed to be chosen who wasn't a hero like them.

'Their weapon is a Chakram... how strange.'

"Oh... what an interesting opinion that boy has." The feminine voice faded, along with the figure in the hooded cape.

"Hmm, is it a woman? Her voice was so fierce!" Erika sounded surprised.

"Be careful, Ryuji, there are many women stronger than us that have their eyes on you... We've been noticed, and there are likely two or more here." Yumiko's sexy, alluring voice and words were a warning, but Ryuji ignored it as they reached their seats that were beside the entrance to their waiting room.

"Yeah, yeah... I have you two. Why do I need inferior women?"

"Look, the princess is going to make a move, Ryuji! Eh... why is she looking this way?" Erika pointed towards Princess Anne in her full plate, who seemed to look towards Ryuji after grasping her greatsword and pointing at him, then the enemy.

As if saying, 'You're next!'
