"Yeah yeah, oh by the way id like you to meet someone" Sans smiled suddenly getting a evil plan, "hm? Who?" G.Sans asked looking up from his blueprints. "Flamboyant guy friend of mine, come on" Sans guided the other Sans to a small house in waterfall and he knocked, "this house is pink" G.Sans took a step back. "Chillax" Sans chuckled.

"Who's there?" A voice said opened the door to see two Sans but the older taller one was... My my... Wasn't he handsome. "Oh hello there Sans.... And... Who's your gorgeous friend" He purred pulling the two inside, He was a black and grey robot with a pink body and G.Sans felt like he had been pulled into something awful "This is G.Sans, he is my half twin brother? Sans made something up. "Half twin brother? What's your name honey" Mettaton ran a finger up G.Sams chin and G.Sans shivered. What did I just get myself into...

Sans smirked a little watching Mettaton totally adore his twin brother, "oh my..." Mettaton walked around him and giving his butt a little squeeze and G.Sans froze. "Sans... Why... What did I do to you to deserve this" G.Sans stare just spoke all.

"Nothing" Sans responded with a shrug and smirked, "Hey cutie, can you come here" Mettaton had walked off into another room dragging G.Sans "Sans halp, I promise never to mock you again, please save me SANS HALP" G.Sans begged. "Have fun" Sans waved goodbye to his calm brother who was not calm no more.

Sans could hear the crashing and explosions listening to G.Sans panicking seeing G.Sans try to run but Mettatons arm extending and pulling him back into the kitchen. "Oh my darling~" Mettaton purred. Sans laughed his head off.

Sans checked the time, he had let G.Sans be tortured enough "Oh Mettaton, we gotta go pick up Papyrus can I have my brother back?" He asked. "Alright I guess so" Mettaton pouted. G.Sans walked out and his face covered in pink lipstick smudges.

"Had fun I see?" Sans teased, G.Sans smacked him as the two left the house "see you soon Darling~" Mettatom blue a kiss and G.Sans cringed
