Their son needs some silver

As Jack and Katie walked up to their son's room, they could hear Finley's gaming loudly through the door. They burst into the room, knowing he could hardly hear anything with his headset on. Katie giggled at the sight of her beautiful silverless son, the thought of silvering him giving her so much pleasure to cause silver cum to ooze from her cunt and down her legs, as dad walked behind Finley to unplug his gaming console.

"What the fuck?! I was in the middle of a tournament! Why wou- holy shit-" as his anger turned to fear, staring at what seemed to be his mother, some alien version of her, all covered in silver with giant milky tits. His eyes oggled his mom's new form, her body giving him an erection that he tried to hide as she slowly approached him. "Oh don't hide that sweety, I think it's wonderful..." as she reached down to feel over his crotch, Finley paralysed with fear with his eyes primaly fixed on her pornstar tits, feeling his mom pull out his cock and feel it in her fingers, slowly stroking the erection as he grew harder in her hand. Finley moaned, his mind telling him to run but the pleasure from his cock keeping him rooted, and his mom's tits seemingly hypnotising him, but as he looked closer he saw her thick nipples leaking something silver? Seeing something so unnatural seemed to snap him back into reality, "Mom, I- I don't know about-" Katie seemed to silence him by pumping his cock faster, "Oh silly, we can't stop now, we haven't even started! Just look at this tiny un-silver cock, but we can fix that!" she seemed to grin with maniacal glee as she wrapped her lips around her son's cock and began sucking hard and fast. The shock and pleasure making Finley shoot up out of his gamer-chair and push his mom off of him, lost for words, he looked down to see his small teen cock had grown to rival a horse's, coated in a silver substance and leaking silver cum, every beat of his heart causing it to violently splutter out more silver cum, each giving him a slight orgasm from the pleasure alone. His mind tried to fight this new pleasure, he wanted to run for the door, but his dad Jack stepped out and grabbed him. Finley looked down at his mother in horror and lust combined, her exaggerated hyper-sexual body coated in silver rapidly crawling towards him as he screamed, she licked her lips and easily took the entire silver monster cock of her son down her slutty throat, **** on the sheer amount of argent parasitic cum spewing from her son's rod, Finley's screams turning to restrained moans.

His dad let his son go, pulling his chin up and passionately kissing Finley, as he moaned into this dad's mouth. Jack instinctively bent his son over, filling him with the full length of his silver shaft. No matter how much silver was pumped into him by his dad, or how much he endlessly thrusted and came into his mom's mouth, there seemed to be endless silver and endless stamina, silver leaking out of everywhere.

After spewing and sucking and fucking silver for what seemed like hours, painting the bedroom shiny, they realised that the silver needed spreading further...
