The Trials of a Different Species Sister: Hentai Interactions with Humans

He no longer gets excited by sex with his beloved wife.
Fujio Takahiko realized this about himself on the night of their second wedding anniversary.
He had always thought of himself as being rather indifferent to sex. But he vaguely realized that the real reason wasn't that.
Soon after getting married, Takahiko began having dreams. The same ones, over and over again.
--The lewd customs of the village where he was born and raised.
--A banquet held every night during the summer festival.
--A female and male writhing and panting in the darkness. The vulgar fragrance produced by animal-like sexual intercourse.
Unable to bear the sheer horror of the customs, he fled his hometown.
Takahiko realized that the religious rites held secretly there had planted an indelible sexual inclination deep in his heart. As he gazed upon his wife, Manami, sleeping with her ripe beauty and adorable face, Takahiko felt a dark heat building up in his erection. And he knew that this heat could only be quelled by returning to his hometown...
"Kagachi-sama... I offer you comfort."
The words spoken by the lips of the woman he admired came vividly back to Takahiko's mind.

Enomoto Ryoka is a childhood friend and the ace of the girls' basketball team.
They grew up together in a rural village, and she was the girl he secretly loved --
 
What kind of acts did she endure?
 
How did those filthy men connect with her body?

Remi was a Demon Lord who barely fulfilled her duties, spending every day lazing about.
One day her underlings had enough of her attitude, cast a weakening curse on her, and drove her out of her castle.
To lift the curse, Remi needs the 4 dispel gems each of her underlings keeps close to them. She must siege her own castle, undoing the curse as she climbs its steps...
Will Remi be able to regain her power, and the comfortable life she once had?

What happens when a hero falls for the demons he's supposed to destroy? Strange circumstances bring a human hero together with three demons, and the four of them set out on the adventure of a lifetime. They don't work well together at first, but after a while (and with a little help from a special item), these old enemies will start to REALLY get along...
 
The year is 1887.
Humankind has been assailed by demonic invaders from hell. For a time, humanity's future was uncertain... until brave soldiers arose who fought back the demons. These soldiers are called heroes.

One such hero, a man named Theo, has a goal in mind: take back the city of Manc from the demons who control it, the Halfas family. But the daughters of said family ended up being a lot cuter than he expected...

An RPG with over 150 monsters to collect!
And if you win in battle, you get a sexy surprise!

Train your monsters to fight, and aim for the top spot! Luckily, you've got a secret weapon: the Cheat Tackle. But is it enough to carry you through the ranks?

In this world, there are monsters call Yarimon. Our down-on-his-luck hero was a Yarimon trainer without much skill... until the day his main monster learned "Cheat Tackle", a move with 800,000 ATK. With this, any opponent will go down in a single hit!

But that's not enough to be the very best. Our hero will need to polish his own skills to seize the glory. But his first victory over his childhood rival was enough to light a fire in his heart... well, that and the reward money.

Wait, there's no reward money? There's just... sex!!?

His rival removed her panties. It seems that this is just how her family does things when it comes to Yarimon battles. And... everyone else's family, apparently! And only when it comes to me!

"Am I out of touch? Maybe it's everyone else who's wrong..." thought our hero.

But oh well! Might as well fuck 'er good! She may have been a virgin, but that's the price of failure... Apparently.

Now that he's defeated his rival, our hero can set out on an epic Yarimon journey of his own. As he travels the world and uncovers its mysteries, he'll also get to uncover the privates of any girl who loses a battle to him. Will he even have the energy left to catch every Yarimon there is? That's up to you!
