System: Alex for your reminder, the requirement for a system upgrade is fulfilled. The time remaining for the upgrade is 3 hours. Best to enter the Harem world as fast as possible and strongly recommend not to use myriad bodies when upgrading.
"Fuck. Trouble.", both Alex muttered at the same time in different places.
"What happened?", Sofia asked when she heard him.
"My system is upgrading. I need to enter Harem world as soon as possible.", Alex said while getting up. Alex in the other place also started his preparation.
"What? Is it dangerous?", Sofia got worried and asked.
"I don't know. Do you want to come with me to Harem world?", Alex asked.
"But you said… ", Sofia stopped while talking.
"Don't worry about too much. We have to come back later.", Alex reassured her.
"Ok. I'll go with you.", Sofia quickly replied. Alex chatted with Sofia for some minutes. Another Alex quickly arranged everything, got naked, and got ready on another side of the world too.
"Okay, let's go.", Alex embraced Sofia and said while stopping the time on Earth. They immediately vanished from there and entered into Harem world. Alex merges his body at the same time.
"Wow, so beautiful.", Sofia said while her mouth widened looking at the scenery in front. She also saw a group of goddess-looking ladies come toward them at fast speed and felt a connection with them.
"Yeah. It's really beautiful.", Alex looked at his wife and replied.
They quickly came and gave him kisses one by one while rubbing his dick in their bellies and pussies. They gave him a warm welcome and hug too.
"What kind of problem this time, Alex?", his mom asked while clamping his dick with her plump crotch.
"Mom, it's time for a system upgrade.", Alex replied while playing with her boobs.
"Oh. Is there any danger, my dear son?", his mom asked with concern.
"I don't know. The system asked me to come inside Harem world for the upgrade.", Alex replied while moving his hip.
"Oh, ok. Let's go to our place first. Bring her with us.", his mom dragged him by the dick and flew toward the castle. The other ladies, helped Sofia to fly and followed them. Alex was thrown into the bed while straddling his dick with his mom's crotch.
"How much time remaining?", his mom ground his dick and asked.
"Around 2 hours remaining.", Alex replied while massaging her boobs and nipples. Meantime other wives surround him from all corners and started to rub their pussies on him while two of his wife started to chat with Sofia.
"We will do quickie then, is it ok?", his mom asked looking around and him.
"Do you want me to cum quickly into all of your pussies?", Alex widened his eyes and asked.
"No silly, quickie for us. We will use your dick for a quick orgasm.", his mom replied rubbing her pussy.
"Oh, I get it. Alright.", Alex replied and nodded.
"I will go first, is it ok with you girls?", his mom asked while looking at the other ladies.
"You go first.", all of his remaining wives replied.
"Thank you.", his mom said and grabbed his dick while putting it inside her pussy. She started to ride him while kissing him and soon orgasmed. She got away from his dick and another one came and did the same thing while some of them sat on his face and he tasted their pussies. The cycle repeated and they were riding him one by one and nobody fainted and waited for their turn. They did this for an hour and they were becoming crazy by the time. Alex finally felt he was at maximum.
"I'm cumming.", Alex said and the person riding sped up the movement when Alex pushed from below. Alex released his semen and she orgasmed and rolled to the side. Another quickly came and started to ride and he cummed inside her while she orgasmed. She rolled to the side and another quickly mounted. The process repeated and at last, he cummed into Anna's pussy. At last, the sex finally stopped with satisfied but not unconscious ladies laying on the bed. Alex kissed them one by one and went to take a bath in the swimming pool because he wanted to upgrade the system there. Soon, all his wives came near him and waited for the process to begin while having chat among themselves. They knew what he was doing so they did not disturb him at all.
