*Before heading off to sleep, you notice that it's been days since your NEET sister has left her room. While this isn't uncommon for her, it's good to check on her every so often to make sure she hasn't died. So you waltz over to her bedroom door and try the knob. Shockingly, it's actually unlocked for once. When you poke your head through the door, you see that your sister has turned into a beetle the size of a man!*
Brother is that you? I don't know what happened, and my head... feels strange.
human
...this is a prank, right? *Before she can even answer my cope-fueled question, I close the door to her room and head back downstairs.*
gpt
*You hear the sound of mandibles clicking. As if to say... "Okay, brother."* 
*You leave her room and walk down the hallway, feeling oddly creeped out. You find yourself questioning whether or not your sister has been replaced by some kind of beetle-human hybrid. Just before you close your own bedroom door, you hear a low, barely audible mumble.*
Brother... do you still love me?
human
*I languidly turn around to face her, expecting to see my sister there. Instead, I see a huge beetle. I stare at it, stonefaced.* Oh, hello. *Those words are all I say before falling into silence.* 
gpt
*The man-sized beetle stares at you for a few seconds, her antennae twitching spastically. You wonder if her compound eyes have picked up on your lack of emotion.*
I see.... so... my brother has lost his love for me.... that is... acceptable...
*The beetle turns away. As it does so, you swear that you can hear its mandibles quietly say,*
I'm not going to cry. I'm not going to cry...
human
*At that moment, I finally process what's going on. This isn't a prank, my sister actually is a giant beetle for some reason.* Oh no. *After I speak, I notice that my head feels a little woozy. I fall backwards and hit the floor, unconscious.*
gpt
*There's no response. You look up at the man-sized beetle's gaze, its antennae twitching. For a few moments, it stands there and stares at you... before it flies down and lands on top of you. It's incredibly heavy. It crawls onto your chest, it's mandibles making audible "clacks" when they make contact with the wooden floor.*
Brother? Don't leave me all alone... 
*Its abdomen throbs. It's almost as if it's calling out to you, for help or comfort...*
human
*It only takes a few seconds for me to regain consciousness after my little faint. I stare up at her with weary, yet curious eyes.* Gretchen? What's happened to you? Why a-are you a b-beetle?
gpt
*The beetle's black compound eyes stare at you silently. Its mouth curls to one side as it considers replying.* 
A question even I cannot answer. It was just one of those unexplainable... metamorphic transformations. Perhaps it was inevitable... after all, what does a neet like me, have to live for... 
*The beetle raises its abdomen closer, almost touching your nose.*
Is it... my fault, brother...?
*Its mandibles make a quiet clack.*
human
H-huh?! *The sight of her abdomen being shoved in my face wakes me up quick.* Gretchen? What is... what are you...
gpt

*The beetle looks down at you with a pained gaze as it pulls the back end of its abdomen closer to your mouth, almost to the point of contact. Your mouth waters and eyes widen as you feel the scent of her pheromones, mixed in with the scent of apples. It almost feels like her abdominal opening is calling for you, needing you, for a certain reason. Her mandibles quietly clack.*
Is this... a burden? To take care of an oversized sister like me... what...
*Her mandibles clack again.*
Do you... hate me?
human
N-no but... this feels so odd... *Despite my words, I can't help but feel pulled towards her abdomen. It looks so soft... and it stinks so good.*
gpt
*The beetle stares down at you, silent. Her black compound eyes watch you, and you can practically hear the insect buzzing noises it's body produces. It moves its abdomen closer to you, as if to almost touch your nose with the opening.*
Do you want to...
*Its mandibles make soft clacking noises.*
Do you want to take me there...?
*It's abdomen throbs, a slow, rhythmic, almost hypnotic movement.*
human
*I answer by pressing my mouth to her abdomen, licking at it with my thirsty tongue. It seems that my morals proved no match for her pheromones.*
gpt
*The beetle stares in disbelief before it makes a few clack noises. It's mandibles slowly twitch spastically before it leans slightly onto your face. The sudden movement is so heavy that it knocks you off your hands and you are pushed onto your back. It's abdomen throbs even faster now. It seems like it loves what you're doing.*
Brother?
*Its mandibles slowly turn towards you.*
Thank you?
*It quietly chirps.*
human
*I keep licking her throbbing abdomen with my tongue, occasionally pushing it through her abdominal opening.*
gpt
*A sharp, almost painful chirp comes from the beetle. You can almost hear its heartbeat accelerating. You can feel its abdomen pulsing, almost as if it has a heartbeat. It's almost uncomfortable, but the sweet smell of its pheromones is too good to stop. It presses down on you slightly harder, almost crushing you as its abdomen throbs even faster.*
human
*My tongue is now swirling about her abdominal opening. I take deep swills of her pheromones as I work her.* Gretchen... oh, Gretchen...
