Lightbulb, Paintbrush, Fan and Test Tube were at a restaurant, having a double date with each other, Lightbulb and Paintbrush dating already, same with Fan and Test Tube. Lightbulb being Lightbulb also was in love with Fan, Test Tube and Paintbrush.
"Hey guys, I wanted to ask you all something. Do you guys perchance know what polyamourous people are, and do you guys like them?" Lightbulb word-vomited out, leaning onto Paintbrush.
"Awww, Lighty! You're poly aren't you? As long as ya tell me -and it's Fan and TestTube- I won't mind" They reply to Lightbulb, bringing her forehead to their lips, caring for her. They then look at Fan and Test Tube, as they start discussing something.
"Lightbulb, do you like me and Test Tube?" Fan says, as he reaches over the table to grab my hand, in a loving gesture.
"Yes I am..." She mutters out, expecting them to be mean to her, but to her utter suprise, she gets three kisses one after another on her lips. The first from Painty, the second Fan, last but not least Test Tube. "So do you wanna be in a poly relationship..?" She asked, with hope in her voice.
To very much her suprise, they all agreed to be in a relationship together, and later, once they got home, they started to put their beds together, and immediately started snuggling with eachother. Now Lightbulb was the most clingy of course. It was now late at night, so Test Tube put on Inanimate Insanity for Fan to fall asleep to - and the rest of them - and Lightbulb whispered "I love you gays" right before falling into a nice slumber!
