The first victims of Grud's sex rampage on the wives who were pleasuring each other were Ida and Reta, they were moaning while scissoring their pussies together and Grud was going to put an end to that.
When Grud reached them, he grabbed them both and stacked Reta on top of Ida facing each other, their fat tits pressing against each other and spilling out the sides making for a wonderful sight for Grud who was between their spread legs.
Ida and Reta already knowing where this was going started aggressively tongue fucking each other's mouths as Grud went balls deep all the way into Ida's womb. As Grud started pistoning, Reta could feel the bulge from Ida's belly hitting her own.
After fucking Ida for a while, Grud pulled his dick out of Ida's now gaping cervix and pussy, and plunged his dick all the way to the hilt into Reta. Grud would keep alternating between Ida and Reta, all the while the two wives were moaning into each other's mouths.
When Grud felt he was getting close to cumming, he laid the kissing pair on their side and put one leg each on his shoulder to get into a good thrusting position, then he started power fucking Ida so hard that the jerks from his thrusts did not let the two wives hiss any longer, so Reta resorted to kissing, sucking, and licking Ida's neck and shoulder.
When the time finally came, Grud gave one final power thrust into Ida's womb and started pumping out his baby batter, and while waiting for his payload to be pumped into Ida, Grud entertained Reta's pussy with three of his thick man fingers digging and scraping her pussy walls while his middle finger found her cervix and started finger fucking it.
After Grud was done pumping Ida full of cum, he was starting to get dehydrated, so he picked up the cumflated Ida gathered both her leaking nipples to his mouth, and started sucking while positioning his dick to Reta's pussy hole.
Soon after, it was Reta's turn to get power fucked, and had her womb bloated like a water balloon. By the time Reta was filled with cum, Ida's tits were fully drained, and Grud was still thirsty, so he brought Reta's nipples to his mouth and sucked while grabbing her fat tits and squeezing to extract her milk faster.
When he was done draining Reta's tits, he left Ida and Reta to rest in the afterglow of getting filled in their baby room, then turned to the last of his wives.
There he saw Oso and Sonu lying side by side, groping and kissing each other while Mita was fisting them.
As he got closer, Sonu was the first one to notice Grud. She tilted her head back to look at him and invitingly opened her mouth wide, tongue sticking out.
Setting this, Grud knew exactly what she wanted. Over the years, Sonu in particular had taken a liking to getting throat fucked, and Grud was very willing to oblige.
Grud got into position over Sonu and positioned his dick which was still dripping with cum and pussy juice at her mouth for her to lick for a few seconds before he slowly started pushing his dick smoothly down her throat and felt the head of his dick pop into Sonu's stomach. That was when he started thrusting.
As Grud was getting up to speed, he grabbed Oso and started draining her tits of their milk too, all this while Mita was still fisting Sonu and Oso.
Knowing Sonu could not hold her breath for much longer, Grud tried to make it fast and willed himself to cum faster, which all the sex pheromones in the air and stimulation of Sonu's throat constricting around his dick helped to quicken the pending flood of cum.
Within less than a minute of throat fucking Sonu, with one hand, he held the back of her head and push his dick all the way into her and flooding her stomach. And before he could finish fully dumping his current cum load, he felt the spasms of Sonu running out of breath and quickly removed his dick from her throat, in doing so, he hosed down her Sono and Mita in the remainder of his current ejaculation.
Upon feeling Grud's hot cum hit her skin, Sonu was in rapture as he smeared the hot jizz all over her body, while the semen that hit Mita was just absorbed into her form.
Now it was Oso's turn, Grud laid her down beside Sonu and changed position. Seeing where this was going, Mita took her hand out of Oso's pussy and shoved it up her ass instead. Immediately after Mita's hand invaded her ass, Grud invaded her womb.
As Oso was getting ravaged in both her holes, Sonu scooped what the cum glazed over her body and slurped it in her mouth, after which she grabbed Oso's face and engaged in a cum swapping kiss.
As Grud was fucking Oso, he was also enjoying the tingling feeling of high density mana of Mita's hand pounding Oso's ass just a few centimeters away from his dick in her pussy, and soon busted a huge load into Oso.
After sliding his dick out of Oso, it was time to give some attention to the last of his wives, Mita, but he also realized how dehydrated he was after cumming so much, to quench this thirst, he needed the biggest milk tank around.
Grud picked up Mita and kissed her while walking to Nita who was still basking in the afterglow of being cumflated.
He transferred Mita to his right hand while picking Nita with his left. Grud skillfully rounded up both of Nita's nipples with just his mouth and started sucking on the gargantuan tits that only Nita had.
After getting pregnant five times, her tits just keep getting bigger. Now they were so huge, that they were hanging down to her bellybutton. One might think these were some saggy tits, but no, it was only because of Nita's short stature that they disproportionately hung down to her belly button, and unlike saggy tits, Nita's were full-bodied, perky, and proudly sticking out.
As Grud was draining Nita's tits, Grud brought Nita's ethereal doppelganger Mita towards his dick crotch first.
As Mita's pussy closed in to get fucked, She positioned herself just right as Grud's dick slid into her snatch and popped into her womb, then he started using her as a fleshlight.
Knowing that it was going to take a while to finish draining Nita's tits, Grud decided to take the slow and sensual as he pounded Mita's womb.
By the time Grud was done drinking, Nita's breasts looked a bit deflated compared to normal and Grud was already edging while inside of Mita. So he put Nita down and hunched over Mita's diminutive form, gathered her mana leaking tits to his mouth, and literally sucked the mana from her tits that grew alongside Nita's.
While he was sucking Mita's mana, his precum that was packed full of lifeforce and mana was constantly leaking inside Mita's womb, which let Mita break even on her mana loss. That was until Grud started shaking his hips violently, and with one last powerful thrust, inflated Mita with his cum than she could process for quite some time.
'I never get tired of this sight.' Grud thought to himself as he saw his cum filling Mita up through her translucent body.
When Grud was done cumming in Mita, Grud pulled out and made his way to a side table with a spread of food that his wives usually prepare when they plan for Grud to really get serious with fucking them.
While Grud was eating to regain his strength for the rest of the night, his wives were getting together to do the same.
Previously, they would use their dedicated "seed bowl" to squeeze cum out of their pussies to drink or share among themselves, but after a while of doing that, they found that it tastes better and is more pleasurable to drink direct from the source and that they liked the different pussy juice infused semen that came from each other. So Grud watched as his wives descended on each other's pussies to suck his cum out of them, if they are lucky, some of them will get an extra flavor boost if the one being drained of semen climaxed.
When his wives were done with their protein rich meal, Grud was ready for the next round. The fucking went on into the wee hours of the morning and Grud left no hole unfilled and not an inch of his wives unglazed with his cum.
He knew he was going to suffer from the lack of sleep the next day, but that was a problem for tomorrow's Grud to deal with, he had women to satisfy.
—
When morning rolled around, Grud forced himself to roll out of bed, drench himself in water from a jug to try to remove the strong stench of sex, and used his well practiced telekinesis to scrape the water off his body.
He looked at the sleeping pile of his cum covered wives, and as much as he would like to kiss them goodbye, they were covered in his jizz and they already said their goodbyes before he fucked all of them unconscious.
Grud prodded Mita awake, who promptly floated above the wife pile and released whatever semen she was unable to absorb in time on top of the other wives before going into Grud's body to follow him along for the expedition.
Grud donned his Monster Centipede armor and grabbed his Monster bone spear along with five smaller custom made monster bone throwing spears. Taking one last look at his wives, he left the hut.
When Gurd made his way to the center of the tribe, the whole tribe was there to see off the expedition members, and along with them were his thirty-five children being taken care of by some of the women of his tribe.
All the women from the tribe knew what was up and assisted Grud's wives with babysitting his children on the agreement that they would return the favor when they wanted some alone time with their husbands.
Grud kissed all his kids goodbye and shook hands with Old Crot who would be acting chieftain until he returned. After saying goodbye to the rest of his tribe, Grud gathered the hunters from his tribe who volunteered for the expedition and joined the main expedition party near the land bridge to the first island.
