True Game Over
Marco and Alice entered in the bedroom, and Alice pulled Marco over the bed, before slithering over it, too.
Alice: ...Now come on, let's mate. Don't misunderstand me… This isn't a normal meal…
Then she reached her vagina with her hand, exposing it.
Alice: Hehe… My pussy is already all hot. Once you're inside, you'll be entangled, and squeezed… And taste incredible pleasure.
Marco: 'I have a bad feeling…'
Alice: Hoora… You want to come inside of me, don't you? Don't you want to inseminate this pussy of mine?
Her insides pulsed. as if it was eager for Marco. And a clear liquid is already dripping, already wet and waiting…
Marco: '...Am I going to die?' ...How much does the ritual last?
Alice: Three days.
Marco immediately shot at the door and tried to open it, but it was clearly closed with the key.
Marco: LET ME OUT!!!!
He banged the door, but nothing came to help him… Alice's tail coiled around his waist, and with a scream, he was pulled on the bed, before he could move, Alice's snake body coiled around Marco and Alice, both were touching each other with their skin and completely naked.
Alice then held Marco's head with her hands while she was smiling with an open mouth.
Alice: The ceremony and preparations for that are quite intense. I will completely draw out your semen, continually for three days and three nights.
Even if your semen dries up numerous times during it, you'll recover while we mate. With that, I'll select the very best sperm, and use that to fertilize me…
Marco: Oh sweet mother of God…
Alice: Don't worry… Since it's you, you won't die. The reason only a strong man can be the Monster Lord's mate is because no ordinary man could endure the impregnation process.
You already have the powers of the Doom Overlord, increasing your abilities, you have the Nine Tailed System... Or Ten Tailed System… How it is called now… You will be completely fine. Now then, let's be connected… I'll take the lead from start to finish. You just need to ejaculate.
She pressed Marco's penis against her hot opening, meanwhile he decided to keep his mouth shut, it was already embarrassing not doing anything while he has sex, if he moans like a girl in heat then his pride will shatter for real…
Marco: Hng…
And then, it entered inside Alice.
Alice: Hehe, it's in. Now, come all the way inside…
The folds inside her rub and massage Marco's dick as it entered in her, enrapturing Marco in pleasure by the time he was all the way inside her. It needed all Marco's willpower to not instantly cum inside her.
Alice: Hoho? It seems like you are doing your best to not cum, don't worry, you will come really soon.
Her vaginal walls started to move, tightening and loosening all at random intervals. It was like she was massaging Marco's dick with her vagina. All while gazing at Marco's eyes with a lustful look.
Alice: Hoora… Does it feel good? If I massage you like this inside, it feels like you could melt away, doesn't it?
Marco: Shit… It feels too good…
…
It continued on…
Marco's body was slowly getting dehydrated, his system continued to produce more fluid on Marco's body, and he needed all of his willpower to not fall unconscious.
For three days and three nights, Alice drained all of Marco's semen. When it was over, Marco was barely able to stay awake. It took a full week to recover without the system, both physically and mentally.
Marco fought against Ilias, the Four Heavenly Knights, and dodged all of Alice's attacks using only the spirits, but this was the hardest challenge he ever did…
...
[6 months later]
Marco and Alice were on their way on a hill.
Alice: ...Alright Marco, where to next? We haven't been around Grand Noah recently. I heard there's a food based festival going on…
Marco: Jesus, you need to leave some space for the kids, they could be killed from the size of your stomach if you eat too much.
The two of them were still travelling around the world. The world where angels, humans and monster were all living together…
Meanwhile, Alice uses excuses to eat her way across the world.
Marco: ...Still… The world has changed a lot since the first time we travelled…
Alice: We came together to fight against Ilias, and that common enemy proved a start for our bond. While that memory is fresh in our minds, we will strive for peace. But our children… And our children's children. Will they keep that harmony alive, and live on in peace?
Marco: We are doing our best for this era, what will happen later, will happen. There's no method to stop it, except for avoid that our children become bad people, showing both the good and bad side of the world…
Alice: That's right… We can't take responsibility for future generations that aren't even here yet. We can only make the world the best it can be, for them to be born into…
Marco: I'm sure they will inherit the world… "This" world… Someday our race won't even matter at all.
Alice: Hmm, that's right… They'll love each other. As you and I love each other…
Marco: Yeah… About us… It's really fortunate that the System gave us that ring…
He was talking about the Marriage Ring, Alice looked at it and smiled even more.
Alice: "Until death comes for my head", was it… Since we will die together, maybe we can reincarnate again in another world, like you did…
Marco: Heh, that will be hard to say… I don't even know how it works.
Alice: Well, let's stop talking about death when our children aren't even born.
She gently rubbed her stomach.
Marco and Alice continued their journey to the world once again, armed with the Doomblade, system and dark magic…
