Part 4: Soft vs Hard: metal/hard materials interacting with softer bodies Part 4-A: Soft vs hard - how rigid material might move and to help give an idea of how much you want to stretch and warp it (for instance TFA allows for more flexible movement while tfp is more realistically rigid) Part 4-B: soft vs hard - hard material (digits and glossa/tongue, valve) vs squishy human bodies Part 5 (extra): Glow through the soft human body

4 sketches with swindle and a human 1. Swindle holding a small human in his hand, their head pinned between his thumb and index digit while his other fingers press them against his palm/thumb. Swindle wags his other servos digit at the human, satisfied smirk on his face "My aren't you far from home?" 2 & 3. Shortly after Swindle has placed the little human on his lap while he sits at his desk doing research into what the pits humans are even good for. The human is small enough to be hidden under his desk as it sits there. Swindle seems frustrated. He knows other mechs have human companions, but they seem to be entirely useless. "What the scrap are humans ACTUALLY good for?!" he grumbles. 4. The human while sitting in his lap, spots some kind of mechanism latch on his pelvic panel. The human looks curious about what pressing it would do and what's inside~ 4 more sketches 1. Swindle looks exhasperated, throwing his hands up and gesturing at his screen (pov). "I can't believe it! They're fraggin useless!" 2, 3 & 4. Swindle looks startled with a blush on his face as the human unlatches his pelvic panels and peeks inside, the 4th sketch showing a pov from inside the paneling looking at the blushing humans face. Theyre biting their lip and rubbing their face while they eagerly pull the panel open. Swindle smirking down at the camera/pov, lookin less startled, a smirk on his face. "Hello there! Well maybe you're not entirely useless..."

(this is spose to be some time after their first encounter n his little human is now a personal assistant or "pet")
3 panels in sequence 1. Human with a jacket with an S on it is standing in front of a spaceship door. Theyre holding a datapad n seem occupied by it. 2. The door opens with a FSSSH and on the other side is the face of Swindle. The human and Swindles eyes meet n they both seem equally surprised to see each other. 3. Swindle breaks the silent with a smirk "Hello, pet! Not often you see me down here". The human looks mildly exhausted/bemused or at least not very faced, clicking on their datapad with a beep to keep doing what they were doing. Swindle is laid out on the ground, bound up with a series of straps keeping him from transforming and from getting up from the ground. He explains how he got on the ground like that while the human sighs and hops up on his helm and casually makes their way across his body, still fiddling with their datapad and moving with a casual air that suggests this isn't the first time they've found their "master" (or boss rather) in a situation like this. Swindle: "Can you believe it? They PAID even after leaving me like this! I tell ya, gorlons are some really decent people. Violent and odd, but polite" The human stops at Swindles pelvic plate, sitting down on the jutting metal. "Say, why don't ya help me out of these straps, pet?" Swindle continues. Theres a moment of silence as the human just stares at him. Their face contorts into a devious grin and Swindle is suddenly alarmed. "W-what's with that look?!" he stutters, the human lettin out a low giggle. With a dismissive but worried tone, almost like he's trying to tell a cat not to tip over a fancy vase, Swindle protests "Nooooo...No. Bad!" The human gets up to a number of naughty little misdeeds. Testing out an experimental vibrating tool in Swindles aftport, pressing it deep into him by placing their bootheel against the base of the tool and grinding into him. Meanwhile they casually text pictures of Swindles valve and aft to a mutual friend "ay, rate my boss's pussy". Swindle protests, struggling to speak with the vibrations inside him, his valve dripping wet, twitching n squirting. His aft jerks but cant get the human off him. "P-please tell me it doesn't go higher!" At another point the human tries out a bigger vibrator, more phallic in shape but very large and heavy. They accidentally set it off before even putting inside Swindle, the human and toy vibrating shakily across the floor as they struggle to stay upright with the violently rumbling tool in their arms. The human has to basically hug around the plinth of a vibrator since its so big compared to their small organic frame. Swindle in the background yellas at them to put it down. The human sucks on the outer node of Swindles valve, lapping at it while pressing their thumb up against the base of it, firm grip makin sure the bulb stays taught and primed for any stimuli. Their other arm hugs around a large vibrating pillar lodged deep inside Swindles valve, rumbling loudly while the human uses their body to massage it up and down against the jeeps walls. Swindle pants aggressively and frantically. The normally silver tongued mech is unable to speak, too riled up and overloading repeatedly, his brain module can't form any coherent thought. At another point the human works a series of rumbling beads into Swindles spike, tingles working their way through the member, inside and out, from base to tip. They've left toys inside the mechs other ports, making sure each pelvic component is getting its fill and then some.
