Today, I hope, will be a relaxing day. And since it is Summer, why not have a pool day? Oh, right. We don't have a pool. Well, no problem. It isn't that hard to make a pool when you have magic. First, I will dig a hole. I'll use a standard rectangle design. Done. Now, I need to create plumbing for it. Done. Next, I need to use concrete and a steel framework to make sure that it would hold the weight of the water. Done. Now I need to use the Flames of Faltine to aid in the drying of the concrete. I need to be careful, or else it would create cracks. Done. Now, I need to plaster the concrete and add some design with tiles. And lastly, I'll make a deck for the pool. And, finished. I then left to invite everyone in the house for a swim.

(Pool)

"Mom, Dad, Raynare, Asia, Grayfia, Rias, and Ophis. I just finished building a pool. Do you guys want to go for a swim?" I said.

"Really! That's great! But first, let's go out shopping for some swimsuit," Raynare said. Asia and my mom were excited, Rias as well. As for Grayfia, if anyone else were to look at her, she would look neutral, but whenever she looks at me, she would have this look on her, and you would know that she was thinking of something perverted, but it would disappear very quickly.

"By the way, where are Xenovia and Irina? They were here earlier," I asked.

"They left to buy clothes. I told them that if they are going to live in this house, they are going to wear proper clothes, not whatever it was they were wearing," Mom said.

"Ha-ha-ha! Whoever designed those 'combat clothes' is perverted. If they wanted to make something that makes fighting easier, there are better ways than a tight-fitting, whatever that is. Though, they look sexy wearing it," I said. Then my mom smacked me in the back of my head before she took the other girls as they were going out to buy some swimsuits, Ophis included. But before Rias left with my mother, she asked if she could invite her Peerage. I agreed and asked her also to invite Sona and her Peerage.

Four hours later. Four! That's how long the girls took to buy one swimsuit each. I don't get why they take so long. They all look great in just about any swimsuit they wear. Oh, well. What's done is done. Along the way to buy their swimsuit, my mom and the others met with Irina and Xenovia. Both were dragged into buying swimsuits.

When the girls got back from shopping, they changed to their swimsuits and got ready to dive into the pool. That's when the doorbell rang. Sona and the others have arrived. They got changed too.

Raynare, Asia and Grayfia look great! I wanted to see Sona's swimsuit, but she is hiding it behind a towel. She is fine being naked in a small group, but bigger ones such as now, she started comparing herself with them.

"You girls look great! And Sona. Why are you hiding behind a towel?" I asked.

"I-I…It's just that I don't have the same figure as the others," Sona said. Looking at her Peerage and Rias' Peerage, she is on the small side.

"So, what? You are beautiful just the way you are. You don't have to hide just because you aren't as big as the others," I said. I do mean it. She looks beautiful just the way she is. That was enough to make her drop the towel.

"Now, come on. Let's go for a swim," I said. I then lifted her and ran towards the pool. Then I jumped in, Sona in hand. We made a big splash that caused those nearby to get wet.

During the summer heat, everyone enjoyed the pool, too bad that I couldn't build the pool outside in the backyard since it wasn't big enough. Some of the people decided to play water volleyball. Sona is quite a monster at water volleyball. Petite but strong. I like that. After swimming and playing games for a while, I decided to head to one of the pool chairs to rest. It was then that Xenovia approached me.

"Hyoudou Issei," Xenovia said.

"Hey, Xenovia. Are you enjoying your time?" I asked.

"Yes, but I need your opinion. This is the first time I've worn a swimsuit. Does it look good on me?" Xenovia asked. She then twirled around.

"Hmm…Looks great," I replied.

"Good…Now, how about we make a baby…You can take off the swimsuit that I'm wearing," Xenovia said.

"Whoa! You're serious about what you said the other day?" I said.

"Of course. And what better time than now since everyone is distracted. We can sneak out and return before anyone notices," Xenovia said.

"Ha-ha-ha! Sorry! Sorry! Do you think that if you had sex with me, it wouldn't take long? Ha-ha-ha! That's funny!" I said.

"What? But I read online that guys normally last ten to fifteen minutes. And the more sexually inclined around thirty minutes," Xenovia said.

"Yeah. That's true. But only for normal humans. I'm not exactly normal or human. The last time Raynare and I had sex, it lasted for four hours," I explained to Xenovia. She then realised her mistake.

"So, you're saying we should do it when we have more time? If that's the case, I'll make some plans to have you alone for at least two hours," Xenovia said. She then dashed out of the pool area.

"Wait! Xenovia! That's not what I meant!" I shouted. Everyone heard my shout, and they looked at me.

"What? I was trying to tell her that she misunderstood what I was saying," I said to the people that were looking at me.

At the end of the day, everyone returned to their abode, except for Sona. Mom wanted to talk to her. She found out that Sona was my fiancé when one of Sona's Peerage members, 'Ahem Tomoe Ahem', mentioned it to my mom. I don't know what they are talking about, but it's best to let her speak to Sona since I don't want to incur her wrath. Their talk lasted for an hour.

Later at night, while watching Tv, I felt teleportation magic activate in Rias room. I also felt that the teleportation backfired. Whoever it was that tried to teleport inside the house will be in pain. I don't know who it was, but I'm happy that they'll get the pain they deserve for trying to sneak into the house. After twenty minutes of watching Tv, I decided to go to my room.

While heading to my room, I thought about the fun I had all day, and then I realised something. After seeing Grayfia in her swimsuit, I saw her talk to Raynare and Asia, but I don't remember seeing her again. I tried to remember if she was with us when we played water volleyball or anywhere nearby. I don't remember seeing her.

When I was about to open the door to my room, it opened, and I was pulled in. I looked who it was, and it turned out to be Grayfia. Looking around the room, I can see some not so vanilla equipment on the bed.

"I want you…Master…" Grayfia whispered in my ear. Being called master turned me on. I snapped out of it very quickly and asked Grayfia a question.

"Where is Raynare and Asia?" I asked.

"I spoke to Raynare-sama and Asia-sama earlier. I asked them if they could give you and me some space tonight. Raynare-sama knew what I meant, but not Asia-sama. Nonetheless, they both agreed to let me have some alone time with you…Master," Grayfia said. Whenever she was saying the word master, she had this seductive voice.

"You know what? Fuck it! Let's do this," I said. I then grabbed one of the paddles that were on my bed. I made Grayfia bend over, and I smacked her ass with it. Her moans were a turn on. I continued smacking her ass until she was very aroused and ready.

Since Grayfia pulled me into the room, I didn't have time to put up a silencing spell. Everyone that was in the house heard everything. They heard Grayfia shout to hit her harder. Then they heard her say to gag her with my dick. It was an interesting night for the entire household—an interesting restless night.
