His brother

Liam was reclining on a sofa, waiting for his brother to finish with the shower, before hearing him walk into the room, "Hey man, woah... are you ok?", Liam asks his silver slut of an older brother.

No words are spoken as Jamie looks down and sees the bulging cock and cum drenched towel glistening on his brother, Jack just walks over to the couch and plants his infected shiny lips over his younger brother's and starts frantically kissing and sliding his tongue all inside his mouth.

He doesn't care that it's his sibling, that he's kissing another male, the only thing he knows is how pleasurable this is, and how much pleasure they're both about to have. The silver was already rapidly being produced within has already started producing spores within Jack, every drop of shine being incredibly potent. His brother feels this effect, he's never had a kiss like this before in his life, but the silver rapidly makes him understand as he quickly catches up and embraces his sibling's love.

Jack slides Liam's sweatpants off as he sees the hard, but small, cock. Suddenly, an idea strikes Jack. Much like how animals have natural instincts to build nests, to find the ocean, the silver slut corrupted by the mutated shine instinctually slides his pants off and starts cumming effortlessly into his hand. His cum looking , thick, shiny in the light, a heavy musk that nobody could describe, but every single human on Earth would crave forever if they got a whiff. With the corrupted cum smothered in his hand, he slides it over his younger brother's cock, coating the silver over his rod and balls as he continues to kiss and share mouth loads of saliva. As he gives his son a handjob, he starts to feel his little brother's cock rapidly expand in his hands. What was once a fairly smaller than average hard on is now swelling in length and girth, so thick that Jack's hand can't wrap around it fully anymore. The younger brother tensing as he feels something happening, he has no idea of the pleasure that his body can produce as he moans heavily into his brother's hand as he releases strings of thick, heavy cum from his still swelling argent cock.

The two brothers continue their love making as Jack puts his little brother on the edge of the couch, head in between his legs as he starts sucking off his swollen, impossibly large cock, drinking every drop of amazing cum while Liam moans and groans, as his older brothers shoots a long slender alien tentacle out of his throat and down his brother's, face fuckign him as he sucks on the beautiful silver cock, Jack's long alien tongue sliding all around Liam's enhanced fuck-rod, all while Jack's asshole unleashes another set of tentacles, slithering up to his younger brother's asshole and circling the rim, before slipping up into his ass and slicking the insides with silver, Liam's tight asshole opening for the new alien tendrils as they explore his brother's prostate with corrupted silver tentacles, bringing him to prostate orgasms time and time again with zero respite. Jack's long, slick tentacle sliding out of his own gushing asshole as well now and filling his little brother's needy sissy ass, pumping endless fluids into his brother as tentacles from the older brother are wrapped around Liam's body, twisting over his chest and ramming down his throat. The younger brother is in nirvana, his body being used and filled with endless corruption, endless bliss, just being pumped from all possible holes like a perfect silver slut.

Nearly half an hour goes by as they're both addicted to eachother's silver taste, bodies, loves, minds lost in lust...
