Ash's family seemed to be growing without end. Many of his wives have already given birth, some still had yet to do so. Not only that, but Pikachu's eggs had hatched along with his other Pokemon's eggs, and that added to the family as well.
Safe to say, his house wasn't very silent, whether it'd be him having 'private time' with one of his lovers, or the cries of his children that hadn't turned a year old yet.
At the dinner table, Serena's mother Grace was visiting to come check on her daughter and to see her grandchildren. Her daughter was one of many who the Pokemon Master had gave twins, which made her happy. However, it did bring up some thoughts. And right now, she was staring at her daughter who was holding her grandson, but also something else.
"I'm still surprised that you're pregnant again. Don't you think it's a little early?" Grace asked.
"Oh, uh..." Serena says while looking down at her pregnant belly. "It's gonna be fine. I know Ash will treat them well." She then says before looking over at her husband who was rocking their daughter to sleep, Pikachu hopping past with a baby Pichu and Buneary on his back.
"Yeah, he's busy from time to time, but he's not a bad father. He's already got a lot anyway." Misty says before her daughter started crying in her arms. "Up, that's feeding time. Sorry." She then got up, her belly showing off her second pregnancy and left the room.
(Later)
Grace was walking through the halls after paying a small visit to her grandchildren. Her mask of happiness faded. Seeing her daughter so happy with a man she loves enough to have more than one child made her happy, but also sad at the same time. She remembered the day her own husband left her after learning she had become pregnant.
Part of her wished that she had what all the girls in this mansion had. Not only a man to love but to at least have another child. Though, she figured that helping take care of her grandchildren would be the same.
As she passed one room, she slowed to a stop. She turned her head to see one of the rooms was open a crack, a small bit of sound coming through it. She opened it a bit and peaked through, being shocked by what she was.
Her daughter: Serena was on the edge of the bed, wearing the performance dress she used to wear when she was younger, moaning as Ash was in front of her with his pants down, bucking his hips into hers. He held her legs up while she had her arms wrapped around his neck, her belly pressed against his own.
"Oh, Ash. Please don't stop. ~" The blonde moaned out.
"I won't." He says before he started kissing her.
Grace couldn't believe what she was seeing. The fact that not only her daughter would wear her childhood dress for such a thing, but that she was having sex even while pregnant. It came as a shock to see, but... it sorta turned her on.
She continued to watch, mesmerized by the sight and starting to imagine herself in her daughter's position. After a bit, they came to a stop, and she watched her son-in-law pull out. From there, she could see how big his member was.
At that point, she decided to slowly close the door before rushing away to one of the guest bedrooms. Her face was red and she could feel her heart racing, not only that, but she could feel wetness in her lower regions.
She pulled down her pants, seeing how much she was, but while she felt shame... she slowly reached down and started rubbing against her wet folds.
(Early morning)
Ash groaned as he started to wake up. He had a familiar feeling of morning wood, however, he felt wet and heard a little bit of a slurping sound. He slowly started to sit up and saw a big lump moving in his bed. He assumed it was one of his wives and smirked a bit.
'Alright, let's see who it is this morning.' He thought to himself.
He reached for the sheets and lifted them up, wondering who it was. Then to his shock, he found his mother-in-law: Grace underneath, in her underwear, licking his shaft.
"G-Grace!?" He shouts in shock while crawling back a bit. "W-What are you doing?"
"I'm sorry, Ash. I know this seems unethical, but I couldn't help myself." Grace tells him.
"W-Where did this come from?"
"I saw you with my daughter yesterday and I couldn't help myself." She then crawled up to him.
"Woah, woah, wait, what about Serena? Are you really okay with doing this to her?"
"Please, let's keep this between us. Just this once, okay?"
Ash sweated for a moment in thought. Knowing how lonely she was from not having her husband for so long, he felt bad for her.
Now that he could see her body barely covered and mostly exposed, he could see her well-endowed body with her bra holding together a good amount of cleavage. He thought she was beautiful, but didn't want to stare at her, especially with her daughter around.
He took a look at his clock. It was still early, the sun was practically still down which meant that no one else was awake yet. Plus, he did have soundproof walls so no one would hear.
"Screw it." He said to herself.
He then mashed his lips against her and started french kissing her. Grace was caught off guard for a moment, but as she sunk into the kiss, she could immediately feel the arousal going through her body.
He took one of her hands from his face and moved it back down to his shaft. She got the hint and started stroking his member, making it grow harder in her hand. He also reached back and grabbed a handful of her ass, causing her to moan into his mouth.
She was surprised that he was so quick to accept it, questioning it a bit in her mind, but couldn't care less about that right now. His other hand reached up and unclipped her bra, pulling it off and causing her bust to bounce freely.
After they pulled away, Ash grabbed Grace's boobs and started fondling them. Her face was turning redder and redder with each second, rubbing his thumbs against her nipples, pressing them in and licking them, causing her to moan aloud.
"Ah, goodness... keep going, Ash." She says while putting her free hand on his head.
He sucked on one of her breasts while rubbing her other tenderly, getting a firm feel of them. Just as before, she started to feel her body turn hotter, especially down in her neither region as she kept rubbing his tower.
'This is so wrong, yet, feels so good.' She thought to herself.
He stopped what he was doing, and they decided to change positions. Ash sat on the edge of his bed with Grace on her knees in front of him, both naked while rubbing her breasts against his member.
'It's so big, how had I not noticed it before?' She thought to herself while giving it a lick.
"Grace, this feels amazing." The champ says.
"I'm glad."
Grace continued licking his shaft, giving it several kisses to add. His member then squirted and sprayed like a fountain, getting all over her face, breasts, and some in her mouth. She let it sit for a second for a small taste before swallowing it.
"Sorry I didn't warn you." Ash tells her.
"It's fine dear."
"Let's get to the main part a little earlier." He then got up from the bed.
"Alright, just be easy on me. It's been a long time since-OH!" Grace was caught off guard as she was pulled against the master's chest, then felt his tip against her folds.
"I plan to make this the best for you." He says before slipping his member into her entrance causing her to nearly scream out loud. "I'll make sure you enjoy it."
He then began bucking his hips as his mother-in-law continued to moan, her boobs bouncing about as he did. Once again, the heat continued to flow through her body, and she was falling into a state of euphoria.
So many years she's been neglected. So many years she hadn't felt so good. So many years and she finally was getting it again. Only this time, it felt better. Her ex-husband wasn't this big, nor did he give it to her this good.
"Oh... oh fuck!" Grace cried out. "So GOOOOOOOD!" She then came and made a puddle on the floor.
Her eyes rolled back and she had a goofy smile on her face as her son-in-law continued to fuck her like no tomorrow. Her pussy tightened around his member. She wanted this, wanted this to keep going and wanted him to take her as his.
"I'm about to cum Grace." Ash tells her.
"YES! Please, fill me! Make me a mother again!" Grace says.
His eyes widened when hearing that, however, he was too wrapped up in the moment to stop. He lifted her off her knees and started thrusting faster and faster as she moaned even harder. Then he came. He didn't pull out, spraying his cum inside of her, drenching her inner walls and her womb with every bit he had.
He eventually stopped and let her lay on the edge of his bed before pulling out of her, a waterfall of his seed mixed with the puddle of her juices. She was left a panting, sweaty mess.
Ash got worried. He just came inside his own mother-in-law. Sure doing this with older women was hot, however, he was worried of how Serena would react should she hear about this. Not like there wouldn't be any way to hide if she was carrying his child.
He saw that he was still hard as hell, not only that, but it was still dark out. He only sighed before helping Grace back up for another round. If there wasn't any going back, he decided to accept whatever fate lied for him.
(Several months later)
Against Grace's words, it was not kept between them. She was the next in line to join Ash's harem and become his newest wife.
Serena was pissed to learn that her husband had sex with her mother, and he had to go through a bit of a lecture... and some punishment because of it. However, she couldn't change what happened and, in the end, she was glad that her mother wasn't lonely anymore and had someone to love her just as much as her.
Delia was the most shocked. Her and Grace were very close friends, so to learn that her friend was now married to her son and technically her daughter-in-law now, it came as a shock. Still, knowing that her son was able to make even her happy, she was happy.
Right now, Serena was sitting on a chair in the living room while breastfeeding her newborn son.
"Morning Serena." Misty says while entering, holding her own newborn daughter.
"Good morning." The blonde says. "See you're doing good so far."
"Pretty much, yeah. Still mad at him?"
"A tiny bit. Wondering if it's ever gonna stop though."
"I wouldn't count on that any time soon. Where is he now anyway?" Misty says while looking around.
"Oh, he's just... busy."
Busy was right. Ash was in his bedroom, Grace lying her back against him as he was gently thrusting his member into her pussy, rubbing her pregnant belly and swollen-with-milk breasts while kissing her. After a bit, they stopped kissing with a string of saliva connecting their lips.
"Oh, Ash. I've never felt so happy in my life." Grace says.
"I'm glad you do. What kind of husband would I be if I didn't make sure my wives were happy? Especially my kids."
He then lifted one of her breasts up and took it into his mouth, drinking her milk. She only moaned in bliss as he did so. Not long after did he come inside her canal and paint her walls with his seed.
