Neru is waiting for the penetration with her ass sticking out. If she looks behind where Shinji is standing, she can see his cock, and her heart must be ready for it.
However, she had never thought about the difference in the size of the cock, as she had only allowed her late husband to penetrate her.
「Ah... uh…♡ Ah, ahhh...♡」
Her entrance of the secret part, which had not been used for a long time, is pried open and inserted by the erect cock. At this point, Neru realized that it's clearly too big. She bounces her hips, but is unable to move because of Shinji's grip on her.
Due to her repeated climaxes from the cunnilingus, her vagina is loosened up and is producing a lot of love juice. So, Shinji could slowly pulls Neru's hips toward him, and the glans pushes the vaginal walls apart, pushing the glans deeper into the vagina.
Neru feels the sensation of the vagina being pushed apart, reminding her of the first time she had done it her late husband. At that time, she felt pain because she was not wet enough, but now she feels different.
The body, now in heat and fully prepared, can feel the pleasure of being penetrated by a hard and virile cock, and a tingling sensation runs down her spine and blows through Neru's head.
Soon, the head of the cock reaches the depths of her vagina, and Shinji's hips are in perfect contact with her small ass. Neru climaxes lightly with a different kind of pleasant sensation she has never felt before as she is penetrated in a place her husband could not reach.
（Just by being inserted... it feels so...good...♡）
It's obvious because this is a cock that satisfies a succubus and even makes a goddess captivated. So, how could she not be disturbed by the insertion of such a vicious thing?
「I confirmed your deepest part... Neru-san, is there something wrong because you are trembling so much?」
「Nnh...♡ No... nothing at all...♡ Don't worry about it...♡ Just check it out as you like...♡」
「Is that so? I don't think you're used to having your innermost parts probed.」
「Ahh...♡ Ah...♡ Ah...♡ Ahh...♡ There...♡ Ah...♡ Nnnh...♡」
Shinji's fine piston movements are more than enough to make Neru's sexual desire, which has been building up in her abstinent life, explode. She feels pleasure even at the first time she is penetrated, and her vaginal walls respond by wriggling greedily and clamping Shinji's cock tightly.
（She has a good reaction. This is exactly what an incubus is supposed to do. I need to give her more pleasure.）
Taking advantage of the size of his cock, Shinji pulls his hips back until his cock is just about ready to be pulled out, and slowly pushes it deep into Neru's vagina again. The movement changes to such a way that it seems as if he tries to teach Neru's vagina how to receive his cock.
（Amazing~♡ My inside feels good~♡ He is rubbing all my inside~♡ and spreading me out~♡ I can't remember what Van's thing like~♡）
Neru's vagina slowly began to adjust to Shinji's size as Shinji slowly inserted it into her again and again. It is as if Neru's body is forgetting Van and trying to remember Shinji, the stronger male.
（No, it's a lie~♡ Even though I mustn't forget it~♡ But Shinji-san's is too strong...♡ I'll be forced to remember his instead of Van's...♡）
Neru's vagina becomes less stiff when Shinji's cock is pushed in. And yet the tightness remains the same.
Shinji, who feels that Neru is ready to receive his cock, increases the pace of his piston movement. Neru also begins to rock her hips in time.
「Ah~♡ Fuah~♡ Ah~♡ Ah~♡ This is good...♡ Ahh~♡」
Neru moans in rapture. And not needing to hold on to her waist any longer, Shinji removes his hands from her hips and hugs her body from behind.
He undoes the front buttons of her maid's uniform and pulls off her underwear, which hides her small breasts, with <Undress> spell, and throws it away. He then rubs her modest bulge with both hands, and flicks his tongue over her ears.
「Nnnnhh~♡ That's not good~♡ No~♡ Ah~♡ Ah~♡ Not like this~♡ No, Shinji-san~♡」
「What's wrong? Tell me」
Neru feels so good when Shinji pinches her erect breasts and whispers in her ear. Even the warmth of Shinji's body against her back feels good to Neru as she falls. But, Neru thinks that she should not remember the greatest pleasure （happiness） that makes her certain that once she knows it, she will never be able to go back to the way she was before she knew it.
「Because I...♡ I...♡ I have to...♡ Ah~♡ I have to remember Van...♡」
「Why are you so afraid you'll forget?」
「Ah~♡ Ah~♡ Because~♡ Because Shinji-san is so much better than Van, and everything you do is so much better than him~♡ Ah~♡ Ah~♡ It becomes bigger~♡ Nhhh~♡」
Her heartfelt cries of guilt mixed with pleasure fueled Shinji's arousal. And it made his member grows even larger and makes him want to ejaculate into her vagina right away, so he keeps whispering.
「Don't worry, Neru-san. Your mind and body are different. As long as you continue to care for him, it won't be a betrayal.」
「Nnh~♡ Really, really? Ah~♡ Fuah~♡」
「Yes. So please don't worry about it.」
「Ahh~♡ Ah~♡ Yes~♡ Ah~♡ Cumming~♡ I'm cumming~♡ Vannn, I'm cumming~♡」
For Neru, who is near her limit, Shinji's words of forgiveness feel like a revelation. She begins to move her hips boldly and greedily as she climaxes.
Shinji also thrusts her, and their hips come down at exactly the right time. Eventually, he hugs Neru's slender body from behind and pours his sperm into her in the most deeply connected position.
「Ah~♡ Ahhhhhhh~♡ Ah~♡ Amazing...♡ It's so much... Ah~♡ Ah...♡」
The pleasure of having a large amount of semen poured into her uterus. Neru's body completely surrendered to the strong ejaculation while being tightly restrained. As a proof of this, a faint pinkish glow of a lewd crest appeared on top of her vagina.
After a long intermittent ejaculation, Shinji finally finishes, and Neru falls down on the table as Shinji steps back and pulls out his cock. Only Neru's butt are lifted up, and the white semen dripping from her secret parts is a very lewd sight.
「I have examined you deeply, and my suspicions are confirmed. I will not report this case.」
「T-Thank you very much...♡」
Shinji approaches Neru, who is still slurring her words, and move his cock covered with love juice and semen toward her face.
「You shouldn't come to the warehouse alone next time. If you ask me, I will accompany you...」
Shinji puts his glans close to Neru's mouth. Neru's cheeks blush and she takes the cock into her mouth without hesitation.
（I can't be satisfied with masturbation anymore...♡ Van... I've become his thing...♡ But what's important is our memories, Van...♡）
Neru sucks Shinji's cock carefully while keeping the memories of their happy marriage in her mind. After this, the sound of Neru's mouth continues to echo in the warehouse.
