You got Rikako pregnant

You're supposed to search for the one who will bear you your heir, but for the first few months it didn't go anywhere. You're spending too much time with Rikako that you're satisfied with the current status quo. Your grandfather groused always, saying out loud his regret for introducing you to his mistress, as you were spending most of your time with her.

"I'm pregnant," Rikako said one night, when you came to her, showing you the test strip.

To your great pleasure and delight, one of the seeds you had sown inside the married woman had taken hold. "That's great," you said before you kissed her. Lust or not, you're still immensely grateful for her.

"Should we do it as usual?"

"Maybe we let our baby grow a little bit, and become stronger?" you said. You recalled reading somewhere by accident that as long as the two of you were careful, you could have sex even at the early stage of pregnancy. While Rikako may knew better, you felt the need to be on the safe side.

"Alright," Rikako said as she unzipped your pants to suck on your dick. "We'll made do with oral first?" she said, and without waiting for your answer, began sucking it until you cummed in her mouth. She then swallowed it without leaving a single drop to waste. You then returned the favor and ate her pussy.

After a few weeks of oral sex, the two of you resumed your fucking. While some women's mood for sex dropped during pregnancy, hers appetite actually increased as her hormone made her became more and more hornier.

"By the way, your husband knew about our child?" you asked in the midst of your coupling session.

"Yes," she said as she moved on top of you, sporting a small but noticeable bulge to her formerly flat belly.

"And...?"

"It's just another child he would raise in his family name. So don't worry. I promise the baby and I won't be a bother."

"I never thought the two of your are a bother. It's just that I'm curious about what is his thoughts about it."

"Didn't care then, and didn't care now. We have caretakers assisting me in taking care of the children, so he pretty much let me do my things... " she gasped as her sensitive body are readying itself for orgasm.

"Alright," you replied before the two of you start to move faster, but gently, toward the finish. She moaned your name, and you, hers as the two of you climaxed almost as the same time.

After she had recovered, Rikako said. "You have become a better lover, Doe-sama."

It was true. You can consistently bring her to orgasm compared to the first few sessions when you had just lost your virginity.

"Still," Rikako continued, "You need experience with other, much younger woman. Besides, it would be hard to do it once," Rikako rubbed her belly, "This child becomes bigger. So I was thinking... there are some girls that I can introduce to you. Maybe you can chose who will bear your heir?"

"Okay," you said before you start fucking her again.
