Yoimiya knows that if she were able to keep Aether close to her, they could live some kind of happily ever after. They could stay in domestic bliss and have a family together, just her and the man who has become her own personal hero, the man who really is a hero like out of her storybooks. She has known from the start that she wanted something like that with him, and now that he has begun to return her affection, it feels that much more possible.
And yet she knows that it is not possible, not unless she finds a way to make him stay. She knows that his true priority is his twin sister, and that he might leave her forever once his goals are accomplished. Hell, she knows that he does not even plan to stay in Inazuma for long, and even if he lets her travel with him, that does not solve anything. It will not stop him from leaving in the end, will not stop him from leaving her, and that is why she has to make sure that she is able to make him stay, now and forever.
Yoimiya knows that it is for the best, that this has to be done. She knows that he could be so happy with her, that he is happy with her right now, and that he could stay that way, if he only had a reason to stay, something more important to him than his sister. If family is so important to him, and if that is her eventual goal with him anyway, then Yoimiya supposes that she is just going to have to start that family now.
When she rides him, she always gets off of him when he tells her to. He pulls out so that he does not come inside of her, so that there is not as much of a risk. Tonight, as she sinks down onto him and begins to bounce, she knows that she is going to have to take advantage of the fact that he would never do anything to hurt her, thus giving her a bit of an advantage over him. He feels so good inside of her, just like he always does, and she knows that it is going to feel even better when he comes, filling her with his seed and hopefully getting her pregnant.
Yoimiya has been planning this so carefully, making sure that this was the best time to do it. She should be at her most fertile right now, and that is why she is doing this now, tonight. She might only have one shot at this, but she is going to make sure that it happens. No matter what, she is going to make sure that Aether gets her pregnant, and has reason to choose her over his sister, to choose their child over his sister, so that they can live in their domestic bliss, now and forever.
He moans for her, loving the pace that she sets and the way that she rides him, making it all feel so good that he can hardly stand it. She knows what he likes well enough by now, further proof that they are perfect for each other and that he needs to stay with her. Yoimiya could list so many reasons that he should not leave her, that she is better for him than his twin, but since she knows he will not listen to that, she has to content herself with this plan, certain that this is what needs to be done.
“I’m…mm, I’m getting close, Yoimiya,” he moans out to her, and she pretends not to hear him, bouncing on top of him, rising and falling on his cock. His first warning is always a good deal off anyway, so he does not realize yet that she has no intention of getting off of him. Instead, he just stays relaxed and continues moaning for her, continues showing just how much he loves the way she can treat him.
If she were not sure of herself before, the look on his face now would do it for sure. Aether seems so happy right now, clearly enjoying this and everything that she does to him. He could have this forever, if only he let himself give in, he could be truly happy. She is not doing anything wrong right now, just helping show him what he really wants. As he tenses up, she knows he is really getting there, and it is not long before he speaks up again.
“Almost there,” he cries, waiting for her to get off of him. When she doesn’t, he looks up at her, repeating himself, and adding, “I’m really about to come, Yoimiya!” Rather than getting off of him, she begins riding him that much harder, while he grows more and more frantic, telling her over and over again that he is almost there.
“Just fill me up, then!” she finally says, letting him know what she wants him to do to her. “Fill me up and put a baby in me, and stay with me forever!”
“Yoi…Yoimiya?!” he cries, but then he moans out, unable to say anything else. No matter how he tries, he can’t stop himself, can’t hold out against this perfectly pleasurable assault. He has no choice but to give into his orgasm, unable to fight it back as he gives her just what he wants. Her voice breaks as she joins him in that bliss, the two of them coming together, with Yoimiya simply overwhelmed by everything about this. She feels so good to be filled and feels so good to know that Aether was not able to resist.
With any luck, he will soon be hers. He did not try and fight her off of him, and even if he is mad at her, she is sure that he will not stay that way for long. She is sure that he will soon understand why she has done this, and understand the future that waits for them.
