It still sort of left Mr. Saint a bit stunned when he really thought about what it meant when his grandson Zander told him that he was having sexual relations with the other guys living alongside him in Carnal House. He wasn’t sure what to think at first. This was all new to him, after all. Of course, just because it sounds one way when his grandson describes it doesn’t necessarily mean it’s going to work out the same way when he gets there in person. So, being the boy’s grandfather, Mr. Saint took it upon himself to check things out before he felt comfortable sending Zander there. And was he ever surprised by what he stumbled upon! Fathers and sons living openly with each other, not depriving themselves of their true intimacies, or hiding it from the others, either. There was something about seeing the way Hugo and his dad, Mr. Adrii, interacted that sparked a sort of inspiration in Mr. Saint. As though it gave him permission to find a desire buried inside himself. That desire being the sexual bond not only shared only with his own grandson Zander, but with another dad and son as well, in Hugo and Mr. Adrii. Mr. Saint was so intrigued by this new way of living that he accepted Mr. Adrii’s open invitation that he would always be welcome to visit him and his grandson Zander at his home. The two boys, Hugo and Zander, were thrilled to have met each other and quickly bonded. That much was evident when the two older men walked in on the boys making out on the couch.Their boys were clearly celebrating their new living arrangements, bright-eyed and grinning from ear to ear. Their infectious joy made them all the more tempting for the older DILFs. Before they knew it, the room was filled with a collective desire that pulled Hugo and Zander away from each other, Hugo into his father's arms, and Zander into the arms of his grandfather.As their clothes came off, the passion between Zander and Mr. Saint seemed to grow. The fact that they were relatively new to sharing their passion in a public setting just added to the energy between them. Whereas Hugo and Mr. Apolo had had far more time to explore their relationship.While both men admired their boy’s backsides. Mr. Apolo groping Hugo’s cheeks while kissing the boy, Mr. Saint had Zander on all fours, the boy’s jock strap leaving his hole fully exposed so that the older man could loosen his tight ass while rimming the sexy stud. Mr. Saint was still so awed by getting to experience his grandson’s naked body this way that he continued to tease Zander’s hole while worshipping the boy’s hard cock with a hunger that rivaled Hugo as he also took his father’s uncut cock into his mouth. Mr. Adrii’s thick member stretched his son’s lips as the younger man bobbed his head up and down, casually looking over at the secondary man-boy pairing getting physical next to them. Basking in the arousing aura that was palpable in the room.Mr. Saint aimed his thick, ridged cock at his grandson's now loose hole and prepared to fuck, but he restrained his own lust and allowed Zander to back up on it, fucking himself. Overcome with pleasure, Zander rested his head on his friend Hugo's back, as the other young man continued to suck his dad’s cock. Mr. Saint could only hold back for so long. Sensing that his boy was now fully open, he began thrusting his hips, taking his pleasure in the still wonderfully snug hole. Mr. Adrii continued fucking his cock as deep as he could into Hugo’s throat. As his boy took the face fucking, Mr. Adrii reached over his son’s back to take Zander's hand, gripping each other by the wrist, the two couples were joined in their passion.The two men’s eyes met, and no other communication was needed for them to swap places. With Zander on his back, Mr. Adrii prepared to fuck him, while Mr. Saint experienced the pleasure of Hugo’s oral skill, jacking the boy’s cock to reward his efforts. Mr. Adrii didn’t want to breed another boy without permission, so he pulled out. With Zander on his knees, sucking his balls, the man jacked himself to completion. However, he wasn’t going to stop Zander when the boy chose to raise up and lick the cum off his hand, before rising further still to share a cum-flavored kiss with the older man.Then it was Mr. Saint’s turn to fuck his grandson. Zander eagerly welcomed his grandfather’s cock into his now well-fucked hole. Mr. Adrii returned to his son with Hugo snuggling into his father’s arms, watching his friend take yet another fucking. Mr. Saint thrust into Zander’s ass and began fucking deep and hard, now that restraint was no longer necessary and, in fact, he was capable of very little. Racing toward his own climax, there was no need for him to hold back. With a primal grunt, he planted his seed deep in his grandson's guts, finally allowing his wilting cock to slip out and looking down at his cum dripping from the now gaping hole. Sliding back into his own warm, sticky load, he lowered himself onto the boy's chest, sharing a familial kiss, as both couples basked in the fading glow of their communal passion.
