Yes, you do. And you have heard the alternate ending

"Oh, really?" you say, catching on. "I think I've heard another version of the story,"

Inoue seemed surprised by your remark. "You do?"

"Yes," you said. "So the story I heard is almost similar up to this part: The son returned home, only to come back half an hour later. 'Mom! Dad needs to do some typing work!' Annoyed, the wife told her son that his father was very good at his work and didn't need her help before shooing her son away.

"Another half an hour passed before the wife realize 'typing' was the code work for sex. She hastily excused herself and returned home, where she saw the husband was lounging on the sofa lazily. 'I'm sorry. You told our son that you want to do some typing?'

'Yes' the husband replied. 'I've made some handwritten draft, but I think it still needed to typed as well.'," you said, finishing the story.

"Hm... that is interesting. What is also interesting is that you seemed to get the joke of the story," Inoue said. "But, as I said, I already masturbated twice, and changed my clothing to remove the ickiness,"

"What is more interesting is the fact that Midori is fertile and is not taking any contraceptive. She doesn't mind getting pregnant by me, I guess?" You recalled Inoue stating the girls were not trying to get pregnant by her customers. However, Midori not trying to get pregnant didn't mean she was against you impregnating her. Inoue's second statement after corroborate the fact. If you knocked up Midori, you could decide whether you want to take responsibility. "I guess, if she gets pregnant, she'll give birth to my child and he or she would become a backup, just in case?"

Inoue stared at you wide-eyed before she relaxed and clapped her hands. "Bravo. You're sharper than I thought."

"I don't like the way you go about doing this."

"I didn't lie. Not even once. I kept certain information from you but it wouldn't be my fault if you didn't ask, would it?"

You nodded.

"Think about it throughly. Your family has given you a free rein on what you want to do. Sleep with one woman or a hundred, it's up to you. But wouldn't it be foolish for it not to take precautionary measures? After all, you are the only legitimate heir right now,"

"That makes sense,"

Inoue closed her laptop. "Alright. Now we're done with our conversation,"

"Wait! We're not done yet."

"We are. You had your fun, and I would recommend you to continue enjoying it. As for me, I'm going to bathe before sleeping," Inoue replied.
