Summary
Castorice thought she had learned to control herself completely by this point in her life, to know what she wasn't permitted to do... But looking at him, at his smiling face and his welcoming presence, she wanted to touch him, to feel his skin against hers, to cradle him in her arms and press him to her bossom as she welcomed him inside her. Caelus made her heart yearn for the one thing she couldn't have, making her feel the pain of what she was lacking more intensely every day that she spent with him. She hated it, and she loved him.

Not being able to touch each other might be a dealbreaker for most of everyone. But love overcomes all, doesn't it?

Summary
And she knew exactly who she was talking with. It was more than obvious, she had seen that profile picture a lot herself, accustomed to messaging Caelus before sleeping to have a laugh or two with that particular brand of madness of his that still let him function as a human being. And she had noticed even way back, Bronya was more than a little fond of him, but now it had grown into full-blown longing for the Trailblazer.
Seele felt a shiver run through her body as she thought of the two being together for real, but she was good at hiding it, not letting Bronya notice, she thought. "Bronya, I can almost hear your heart beating from here…"
----------------------------------------
Seele takes some bold action to make her two best friends get together... Only for her own feelings for both of them to come back and bite her in the ass.

Summary
“Hmm, you’re so beautiful, Natasha…” He complimented her, making her giggle like a younger girl as he expressed his adoration for her body, her wide hips and sagging breasts giving the woman the body of a mommy, even if she hadn’t had the pleasure of being one. But they were working on it, working very, very hard, taking their time every time Caelus came to Belobog, with Natasha preparing and drinking every supplement she could.
A couple of months had passed, but it still had not happened. Natasha had started to get disheartened, thinking that she had missed her chance, even though she had not even hit forty yet. But Caelus was anything but a quitter, and his encouragement helped her get over it, convincing her that they only need to keep trying. Their precious child would come, no matter what, Natasha was sure.

Meanwhile, Caelus found someone he didn’t expect inside his room, thinking her long gone. “Rappa!”
The ninja woman turned around, her mouth full of sweets she had plundered from the snack pantry, looking more than a little happy. Her green eyes widened once she saw him, the corners of her full mouth curling upwards in happiness.
She chewed rapidly before swallowing it all. “Ninja Baseballer, I’m here!” She cheerfully pronounced before running towards him, using all the superhuman power of her body to give him a tackling hug that sent them sliding on the floor, laying Caelus on his back. “I emerged from the shadows of Pinecany to visit you in your ninja abode!”

Silver Wolf didn’t seem to notice at all when Firefly just turned his head with her hand and started kissing him, amusedly watching his yellow eyes flit between the screen and her face as he was torn between destroying the virtual killer bugs and the sloppy make-out session with his dear girlfriend.
Of course, he chose the second, leaving the team two people short and the controller thrown to the side. Though with Silver Wolf on the case, that was not really a problem. Though she was listening, and she was not pleased with what Firefly was doing.
-----------------------------------------------

Summary
She breathed hard, her big glasses half-fogging with it. Slowly, she lifted her hand, bringing the pen in front of her eyes, dripping her orgasmic juices down onto the table and her skirt.
"Hmmm..." And in a fit of lust, she took it inside her mouth, sucking her juices off it and imagining as if it was a big, hard, fat cock that someone was forcing her to suck.
She quickly took it away, realizing what she was doing and letting out a sigh. "I'm too pent up..." She whispered as she looked at the clock; there was still a half-hour left of being in the office for her. And yet, all she thought about doing when she returned home was to keep reading this smutty thing and masturbating some more.
--------------------------------------------
When Pela's fantasizing from reading too much smut goes out of hand, she decides to sate her lusts by calling Caelus to help her fulfill some scenarios long-stuck in her mind.

Summary
“Ehmm… Hello?” The thing dressed in red told Acheron, holding a broom scaled to its size.
“Hello, is… Is he here?” Acheron asked, racking her brains for information, trying to dig out that name that she had been struggling with ever since the feeling welled up in her before.
The creature just blinked. “Pom-Pom can’t know who you’re talking about if you don’t tell Pom-Pom a name!”
“Is… Is he…!” Acheron struggled, trying to remember so hard that she felt her head almost start hurting. “Is… Is Caelus here?”
----------------------------------------------
A feeling of regret wells up within Acheron just before leaving Penacony, and realizes that she has something to do before continuing her mission. To visit someone in particular.

Summary
"Ah, hello. What brings you here today?" Caelus asked her with a caution that made Black Swan feel almost hurt.
"My, why so cold, dear Caelus? I haven't done anything to you, have I?" She leaned forward, softly touching his chin and looking at his yellow eyes. "But if I did, I ask that you forgive me..."
And then, the woman floated in front of him, slowly rising up from the floor to sit sideways on his lap. "Would this suffice as an apology? A beautiful woman in your lap is something every man desires, wouldn't you say so?"
Black Swan leaned towards him, almost ethereally moving until she could whisper in his ear. "I can do more, if you wish..."
---------------------------------------
Having become jealous of Acheron's relationship with Caelus, Black Swan decides to take action with him, using some more than a little dubious means to get what she wants out of him. But she might end up getting more than what she bargained for.

Summary
“Mmmhaahh…! You’re so delicious…” Caelus finally spoke as he pulled back from the kiss, letting him look at Robin’s face, steamy breaths leaving her mouth as he let her take some air, her beautiful green eyes not able to focus on anything as her brain processed what just had happened.
She had no idea how the cringy, quoting Caelus had suddenly made her half-lose her mind with a kiss and some caresses. “T-That was…”
“Oh. Oh yes, I’m sorry, Robin, I forgot to mention something important…” Caelus murmured, scratching the back of his head and looking at the winged woman apologetically. “The truth is that I…”
And then the door to his room opened suddenly, slamming to the wall as a feminine figure burst inside. “My love!”
--------------------------------------------
Robin has been taking Caelus to covert dates all around the Golden Hour, but when the time comes to express her feelings to him, she ends up coming into the knowledge that he's already in a relationship with Firefly. Neither of them is opposed to taking her into the relationship.

Summary
"Ah! You're awake, I see...!" Hysilens heard the voice of the companion. The pink sea bunny, as she called her before. She lifted her gaze, looking at the pink-haired young woman, unable to hide the despair in her eyes as she looked on at one of her 'captors.'
"Why so mopey? It's not like we're keeping you here; you can go wherever you want." Cyrene told her, probing to see what's on her mind. Hysilens opened her mouth before closing it again, looking at the woman up and down. The power that she uses couldn't be underestimated, and Cerydra paid the price for it. She shook her head, looking at Cyrene. "You defeated me. Conquered me. My life is in your hands..."
---------------------------------------------
Caelus and Cyrene take control of Okhema and dispose of Cerydra. The loss of the Imperator leaves Hysilens without a purpose, but the pair of conquerors have an offer that she will not refuse.

Summary
"Stay like that... Just a bit longer..." Seele heard him grunt in her ear, his voice taking on a breathy, growling quality that made Seele feel some kind of way inside, her insides tightening as it mixed with the feeling of their bodies pressed to each other. "What?! Why?!"
He breathed hard, and Seele felt how something started poking her right where her legs part, a little uncharacteristic squeak leaving her mouth once she realized what it was. And then he finally let it out. "I like the way you smell. I love the smell of your sweat...!"
-----------------------------------
Caelus and Seele go together on a mission outside of Belobog, but when a rockslide traps them in a cave, and the warmth of Caelus' spear makes Seele start sweating, he loses control and spends his passions on her.

Is it Wrong to Ask My Friends Inside a Book to Help Me Pick Up a Genius? by SirJuliusVIII

Summary
All the advice has worked so far; the date was wonderful for them. Especially for Herta. She had never been on such a date before. After all, Caelus really is the first man to try and woo her in such a way. Someone of her station usually seems unapproachable, but perhaps Caelus' relaxed personality helped. Still, even as the outing was coming to a close, with the date completely paid for by Caelus, something bothered him. Something besides Asta always slipping money back to him against his will to pay for Herta's extravagant tastes.
No matter how many times he tries to approach her romantically, Herta either doesn't notice, or ignores it. No matter how many soft touches he gave her or how much he tried to close the gap, it's almost as if an invisible territory didn't let him get close to Herta. He was sure it was not his hesitation, but it was as if every opportunity for it slipped between his fingers, whether he took it or not.
