Not that he would be able to form any amount of words anyway as his raging hard-on was consuming all of his attention. He desperately wanted to "thank" her properly, but he knew that the rock had top priority right now. He could hand out all of his thanks after it was back in his possession.
He shook his head, trying to get Kailyn out of his head for a few minutes to get back at Marco who was most likely bathing in the aura of his wife's hot, giant body.
While he's never been anywhere near their bedroom, he knew where it had to be... well, that and the fact that he could simply trace them by following Sofia's loud moans. As he stood infront of the room, he tried to open the door as slowly and quietly as possible, only to notice that it was locked. He would've kicked it open, no question, but even the doors inside the house was as secure as any leading outside.
So without knowing better, David knocked on the door, hoping one or both of them would open the door. But it was no use, even after a whole minute of constant knocking, Sofia's moans were far too loud for him to be heard. Only after one final, brain-melting moan escaped her body, her heavy breathing was quiet enough to get some kind of reaction from them.
David was more than ready to storm inside and steal his rock back. Marco already had a fantastic life, so he shouldn't get to keep it anyway. But those thoughts quickly got put on the backburner as he felt the ground shake beneath him. And again... and again!
The quakes were getting heavier and louder as the origin of them closed the distance to him. Then... it stopped.
The key was getting turned, unlocking the door. He waited for it to be opened, but instead the entire door was ripped out of the frame as if it was blown away. David was shocked at first, but after seeing what caused the door to be destroyed, his shock turned to a mix of fear and awe.
Right in front of his dangled a massive, flaccid dick which had to be at least two feet long! But the sight beside it was even more insane. Two legs far thicker than his entire body held incredible mass of hard muscles. Just the calves alone appeared to have more muscle mass inside it them than David had in his whole body!
But it just didn't stop. Above this massive dick sat 10 brick-like abs which were glistening with power. They were accompanied by many cobbled obliques stretching across the torso. A giant shelf of pecs blocked the view towards this man's face and cast a long shadow on his abs and David alike. Just by breathing those shelves of raw strength rippled with vigor.
Two huge pillars that were his arms hung from the sides of his torso, one hand holding the door. The giant shoulders lead to unflexed biceps the size of exercise balls and forearms that were twice as big as world record holding upper arms.
Not knowing what to do, David waited for the muscular colossus to make the first move, and so he did. He bent over slightly, causing his 10-pack to densen and squish together with what little room they had. As soon as the man, Marco, got a good look at the comparably tiny and David, he spoke up.
"Ah, David!" Marco said with a booming, low voice. "I didn't expect you to get here this fast. I was just about to get a really good pump, if you know what I mean." He exclaimed as he flexed one of his arms, the giant mass of dense muscle growing higher and higher, reaching far, far beyond his head. "You know what they say, the bigger, the better! And I think they're right." He said, gesturing towards the still 9'6" tall Sofia, gasping for air after the best orgasm any woman has ever experienced.
David tried to form words, but was only able to stutter at random. In the span of half a minute he saw his chances of taking back the rainbow rock reaching almost zero. All the while he was subconciously ogling at Marco's crotch
"What's wrong, David? Has my dick left you speechless?" Marco lifted up his flaccid dick with one hand and swung it towards David.
He flew across the hall and into yet another wall. David felt as if he was hit a some kind of flexible steel rod instead of a soft penis.
By now his back was really hurting, but he was still fine. The only question was: for how long?
As he saw Marco grabbing the rock from atop his pecs and holding it tightly, he knew that whatever was about to happen wouldn't end good for him.
