Undertale

After getting the lesser bitches out of the way, Joseph went to a random mountain that gave him a strange energy, when he entered, he found a pair of futa twins, image four is named Makima, and the other is named Bakima.

The two were studying the barrier that kept the monsters in, using their powers to research souls and find out that Makima has a bravery soul and Bakima also has the bravery soul with a shred of determination. Their lust for knowledge left them in sweaty suits, as the giants they are, having a happy and loving atmosphere when meeting Joseph. The only reason they weren't fucking wildly or jumping on Joseph was because they caged themselves to resolve their will for research. It was elementary for Joseph to simply rip off the cock cages, finding out that Makima had already removed hers and was doing it while Bakima was sleeping, fucking her plump ass and pussy, leaving Bakima to simply think she was having wet dreams. This left Bakima in a pouty mood as she was getting railed, fucking Makima with even greater **** and fury than she had ever used on Makima. The relief of true pleasure after so long was such a relief that the two of them fell asleep after accepting Joseph and his sensual body.

That only left Joseph at the barrier, using his knowledge of Undertale to go around to the hole in the Ruins, falling in. When he woke up and went to Toriel's house, he was surprised to find no monsters along the way. But when he got inside, he was even more surprised by the sight, watching as a revived Asriel with a monstrous cock was balls deep in Toriel's ass and violently thrusting with all his might. The lovely house had been completely turned into a sex den with fucking optimised for the two love birds, having a large blue fuck bed in the middle of the central room that Joseph entered.

When they saw Joseph, they almost stopped, but the pleasure they were having and the emotions they were trying to bury were too great. Joseph had to jump in and 2-team Toriel with Asriel, finishing her off and holding Asriel like a puppet to help him thrust even deeper into Toriel. When they were done, Joseph was finally able to ask them with a concerned tone, learning that Frisk had entered the Underground like the original story, pursuing the genocide route with a hint of futa pervertedness, even getting Alphys killed, a true genocide route that put Sans into overdrive during the fight. But she still won and ended up killing everyone, about to kill Flowey as they got their powers, Flowey being able to turn back into his monster form, Toriel getting resurrected from her dust, Frisk getting L.O.V.E. from simply breathing, and Chara being able to suck out various forms of energy through sex. This situation quickly changed things as Chara mounted Frisk's futa dick and tried to fuck out her powers from her, gaining a constant increase in power but not the power itself. As for Asriel, he ran away to the Ruins while the two were distracted, meeting up with Toriel and embracing one another, succumbing to the lust of their carnal and incestuous relationship to cover their woes. They didn't have the strength to fight, but even more, they still love Frisk and Chara and thus don't want to kill them, presuming they could. Joseph felt similar, believing that he could help them improve themselves for the better; save them, after all, they were just kids, they might have spent years thickening and growing into busty and stud-like forms, but with only the two of them, their maturity stopped as all their time was spent fucking and trying to assert dominance. He vowed to redeem them, taking the two into his harem where they would be cared for and one day see their lost family once again, getting Toriel and Asriel to combine their powers to restore the monsters and boost them with solid bodies. Joseph then ran at top speed to Chara and Frisk, running past many monsters who were still in a daze from just dying, and thus didn't imagine another human running up to them was gonna be a nice encounter, attacking as he ran past. But they weren't much of a threat, allowing Joseph to get to Asgore's palace, running past Sans and Asgore, who were conversing, getting to Asgore's bedroom and seeing as Chara was sucking Frisk dry with a plain face as Frisk tried to resist her, quickly getting back her vigour and fucking the blushing Chara with a fresh vigour.

The two of them had been like this for years, fighting and fucking for dominance, reaching the same levels, a feat of power that could have broken the barrier and shattered their world if they bothered to stop fucking for superiority that none of them would get. Joseph quickly took his clothes off, shooting his dick into Chara's mouth as her ass was getting plugged, getting sucked off with the power of a black hole, at the same time, he deflected Frisk's attack while he was getting his strength sucked out of him. Thankfully for Joseph, this power was protected by the 'systems', a power and authority higher than the angels and archangels. It stopped Chara from sucking up his stats, but his base power was gone within an instant, shocking, chilling, and enraging Joseph, who made his dick bigger and then began attacking with greater fury, blowing Frisk off and impaling Chara on his cock, lifting her up and nearly poking out the other end. But Frisk wasn't about to be outdone and shot her cock back in, causing the two to meet in the middle of Chara, who was taking on more than she could handle, feeling immense pressure. But that pressure was nothing compared to the power of their cum hitting one another, filling up her body with semen and getting absorbed as she was foaming cum. A bright light then struck out, and Chara floated above them, proclaiming herself the Goddess Of Semen, instantly getting pulled down by both of them, who flipped her onto her back and fucked the other side of her body that the other hadn't been able to with Joseph's inclusion. Chara then straightened out and led the discussions for her and Frisk, accepting the position as wives, vessels, and an addition to the harem, finishing off Joseph's saga for his scripture.
