Their son also needs some silver

All three silver sluts heard a noise come from the otherside of the house. "Oh come on that's clearly cheating, not even funny!" Finley seemed to be raging at some videogame. All three silver sluts turned to eachother and grinned, as they got up and began heading to Finley's room.

As Jack, Katie, and Sarah walked up to Finley'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 and Sarah giggled at the sight of the soon to be silvered teen, the thought of silvering him giving them so much pleasure to cause silver to ooze from their cunts and flood down their 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 and sister, some alien versions of them, all covered in silver with giant milky tits. His eyes oggled mainly at his sister's new form, he had always had sexual fantasies about her, watching her from the shower and sneaking peaks at her, but this was totally different! Right? Her new shiny body gave him an erection that he tried to hide as she slowly approached him. "Oh, Finley. I know you fantasise about me, I used to think it was creepy when you'd watch me shower, but now, I just need to feel good together..." as she reached down to feel over his crotch, Finley didn't move, his greatest fantasy was now staring him straight in the eyes, fixing on his sister's new shiny pornstar tits, letting her pull out his cock and feel it in her fingers, slowly stroking the erection as he grew harder in her hand. Finley moaned, seeing his mom approach now, a wide proud smile on her face from what she was watching, as she knelt down next to Sarah, embracing her in a deep kiss. Finley's mind and cock were in agreement, keeping him rooted in what must be a dream, and as he looked closer he saw their mouths seem to swap some kind of silver fluid between them, dribbling from their lips? Seeing something so unnatural should've snapped him back into reality, but his mind seemed to accept this new reality readily. His sister broke away from the kiss and seemed to grin with maniacal glee as she wrapped her lips around her brother's cock and began sucking hard and fast. The deep pleasure making him sink into his gamer-chair, his foggy mind registering his mom walking over and planting a deep kiss now on Finley's lips, his eyes bulging from the shock but then relaxing as he accepted the kiss passionately, swapping silver with her.

Dad Jack stepped out and began spitting on Finley's asshole, then slowly one by one putting fingers in, until he could easily fit an entire fist up his son, fisting him deeply as Finley began to splutter silver out of his ass, showering Jack and Sarah in shiny bliss.

Flooding eachother with the shine, as they fucked every hole in every position in pure orgasmic ecstasy. After a long while they realised they couldn't be so greedy, the rest of their family, friends, even strangers needed to know about their amazing secret, they washed off the silver in the showers, bringing towels with them as they got in the car, all masterbating thick silver slime into the towels, as they drove to their next location...
