I WANT TO FUCK BLOT

"Hey Anon, can you come here?" Blot calls from the other room. You walk in to find the room dark save for the pale light of your battle station, silhouetting the huge fembot hunched over it. Even as a 'small' Cybertronian, Blot is far larger than you, and why exactly someone would build a robot to look chubby is anyone's guess. You turn the light on (Blot grumbles in response) and walk over to her: within a few meters you're hit by her musky, oily smell, far stronger than usual, and you immediately recognize the red background of a NSFW board on the screen. You sigh: you've told her a hundred times you don't want that weird shit in your history. You gently chide her and try to convince her to close the tab, only for her to reach out and wrap a large arm around your shoulders. She pulls you in close against her body, your face pressed against her moist, heaving chest. Trying to wriggle free of her slick grip, you see what she's browsing: a sweat/smell fetish thread. She's become absolutely obsessed with those sorts of kinks ever since she learnt that humans sweat, convinced that her unique, disgusting abnormality is a Transformer equivalent of it.

"Anon, I feel really hot," she rasps, her claws running through your hair. Oh, Unicron, no. "I- I need you to do the thing." You start protesting and up your struggles to get away from her, but flesh and bone is nothing compared to a ton of galactic steel and living iron, greasy though it may be. She forces you over her fat, round thigh and onto the floor between her legs, and guides your face towards her crotch. You face a twitching, drooling slit, thick rubbery lips opening and closing as if breathing, discharging a thick sludge all over your computer chair and wafting out an obscene stink. Your cock twitches wildly in your pants, caught between turning rock hard at the pheromone laden stench (do these robots even have pheromones?) and retreating inside your body in disgust.

"I'm- I'm really happy that humans like smells. You like how I smell, don't you, Anon?" she gurgles, smiling down at you anxiously. Before you can respond, another jerk of her claws forces your face into the slimy, gurgling darkness, and you feel flexible metal and supple polymer against the back of your head as her thighs lock shut around you.

You don't know how long you're trapped there, hearing her moan and gurgle as she scrolls through who knows what sort of degeneracy, all the while grinding her hips back and forth, rubbing her noxious slit all over your face. Eventually you give in and start to lick, hoping that making her cum will get you out of this sooner. The olive green sludge she's constantly leaking tastes like sour, salty yogurt.
As her moans grow louder and movements grow more frantic, you know she's close. Eventually with a long, gurgling groan she cums, spurting foul slime all over your face, humping you wildly.

WHRR-TSCHZZ-TSCHZZ-TSCHZZ-CHK
In the throws of her orgasm she suddenly transforms! Her thighs spread open as she spasms and shifts, allowing you to gasp for air. You hear the sound of plastic crunching as her trembling claws crush yet another mouse into shards, and wiping gunk from your eyes you stare up at the drooling, moaning, shark-like head of her monster form.
She eventually comes down, panting and gasping. You try to crawl out from between her legs, only for her to pick you up and hold you close. The rubbery lips of her monster form lock around your own and she forces a metallic, prehensile tongue into your mouth. Once she breaks the kiss, she begins to lick the disgusting slop from your face. "Uhh, thank you Anon. You're the best." She nuzzles you and sets you down in her lap. "I'll clean you up now, just like how you give me baths. S-sorry about the mouse. I'll get you another one, uhuhuhuhu," she adds, laughing awkwardly.
