Summary
Lightbulb knows what to do. She has a daily routine: get up, get ready, go to work, come home, and sleep. That was it. That‘s what she does every weekday.
On other days, however, she hangs out with her friends, Fan, Paintbrush, Test Tube, and sometimes others if they want to.
When Lightbulb witnesses something she would rather have not seen, however, she is ignored. Despite being a witness, no one will listen. Because she‘s the comic relief. Because no one listens to her, and they all think that she‘s stupid.
That‘s what she thinks, anyway. And that‘s what‘s true.

Paintbrush, Test Tube, and Fan go into the stream not knowing what Lightbulb looks like naked or what she’s like in bed and they’re definitely going to get more what they expected now.

Summary
Paintbrush is halfway to letting out a satisfised moan when they turn to Lightbulb with the intention of telling her to cut it out, but have to pause when they see the too-innocent smile playing on her lips.
She’s doing this on purpose, Paintbrush thinks, unsure whether to be angry, grateful, or continue to stare and blush like an idiot while Lightbulb’s hands roam across their torso.
Unfortunately, their body decides for them, and they can do nothing but watch, transfixed, as Lightbulb leans in and presses fluttering kisses to their stomach and hips, just barely exposed by the low-rise sweatpants Paintbrush put on after their day was done.
OR: Paintbrush is stressed. Lightbulb markets herself as stress relief. The answer is obvious.

Lightbulb doesn’t know how she should feel- not when something she’s only ever heard of is standing right in front of her. And that she’s got photo evidence to back it up.Bookmarked by testbrush
