I wanted to post for prime 4's release day - here's a reupload of my (now slightly color-corrected) Samus piece from the prime 1 remaster!
Digital illustration of Samus from the Metroid series. She's wearing the Phazon Suit from Metroid Prime 1, and is standing on some steps in a space pirate base from that game, with orange screens and a blue experiment tank glowing behind her. Much of her torso armor has been removed, letting her breasts and massively pregnant belly hang out. She has a large, noticeable bulge under her crotch armor, and her nipples have black barbell piercings. Samus is also not wearing a helmet, her ponytail whipping behind her; an orange holographic visor floats in front of her eyes. Her arm cannon is set to Plasma Beam mode.

I have had basically NO drawing time for the last couple of weeks, but I wanted to get at least a little something of Samus done!
digital illustration of Samus from the Metroid series, in her Zero Suit. Only her bust and shoulders up are seen; her breasts are very large, the skintight suit bulging around them. She looks sternly to the left, her long ponytail swinging. The background is a simple black field with a dark grey S symbol imposed on it.

it's December, time to repost Kimi's big fat kissable balls~
#CobaKimiko
Digital illustration of my OC Kimiko, laying down on the floor facing away from the viewer. She is wearing nothing but a white-collared sleeveless red sweater and light stockings. Her massive cock and balls are laid out towards the viewer, and she looks back over her shoulder with a nervous expression. A red lipstick mark adorns her right nut, and a sprig of mistletoe hangs from the ceiling above her junk. When this was originally posted in 2024, the caption was: "Kimi's balls, Kimi's balls, kiss them right away" as if sung to the tune of Jingle Bells.

I haven't drawn Aidan stuffed & burping in a while, so here's a doodle~
Digital illustration of my OC Aidan, who is naked. His stomach is stuffed tight, bulging so much that it pushes his large breasts upward, enough to hide his chin. His eyes and mouth are open wide as he belches loudly, the strand of hair that usually hangs in front of his face flying away. His nipple & belly button piercings are swinging upward from the gurgling of his belly.

Just an average tuesday afternoon in Aidan's neighborhood!
Digital illustration of my OC Aidan, a tall, dramatically proportioned man with a huge cock & balls, large breasts, and many tattoos. He is restrained on a sidewalk - a classic red ballgag in his mouth, an armbar secured to his wrists, keeping his hands up against his chest, a thick leather collar, and leg shackles. One of his shackles is chained to a small metal post next to him, which is topped with a sighn. He is facing to the side, looking offscreen with some concern, as his body twitches in anticipation. From offscreen, three people have a conversation, differentiated by text color. Orange: "you were right man, this neighborhood is crazy. never got carded for walking down a street before." Purple: "woah! They just like... leave this person chained up out here? For anyone to ... well, y'know ..." Green: "yeah dude! check out his sign. 'Aidan'. orange wristbands can... touch me anywhere with your hands'." purple: "so like... can I grab his boobs?" In a thought bubble, Aidan thinks to himself: "oh god, /tourists/. please stop yammering and /touch/ me already!"

him...
digital illustration of my OC Aidan. It's a bust, viewing him from his left side. He looks over his shoulder at the viewer with a smile, a grey heart floating in the air next to him. Cropped this out from an older piece and cleaned it up a bit.

this is my favorite bit of Aidan lore btw
Snippet of the chat from the first image in the original post. Text reads as follows. Orange: "yeah I fucked Gaidan at a sexpo once, I got a tshirt for it" Green: "cool story bro" Orange: "no literally, he was giving out shirts"

I gotta draw Aidan streaming again... (reposts from 2025 / 2024 / 2023 / 2023) #CobaAidan
digital illustration of my OC Aidan, specifically a stream of him doing a "YOU LOSE YOU SUCK COCK CHALLENGE" for a game. Mathis, face unseen, is standing besides Aidan as Aidan sucks his dick. In a screen-in-screen, a game over screen is seen. To the right is the stream chat. Digital illustration of my OC Aidan, who is doing a kink stream. He is dressed in latex fetish gear, and a masked Mathis is standing behind him, gripping Aidan's belly. The stream chat is seen to the left, and a bunch of messy dishes & food containers are on the table behind them. Dialogue is as follows. Aidan: "you r-really like this stuffing thing, huh..." Mathis: "mmmh <3 your followers certain do. isn't that right, chat? they don't get to smell you, though. that's all for me." Aidan: "y-yaeh. Can I... take a shower yet?" Mathis: "quiet, bitch. you know there's NO showering until you stop making daily donation goals. your naughty followers want you niiiiice and musky while I fatten you up~". digital illustration of my OC Aidan, who is doing a kinky gaming stream with the chat shown to the left. He is mostly naked except for fishenets, cages on his cocks, and a bright red collar + leash that leads offscreen. He nervously says: "H-hi, gaymers... Since I keep ending my topless streams early because of premature, um, 'bonus time'... I asked a friend to help train me to not nut so fast." Digital illustration of my OC Aidan, who is doing a kinky gaming stream, the chat shown in the top left. He is standing up, wearing a white VR headshet and holding VR controllers. He's dressed in a tight white band shirt, striped stockings, and a leather harness. His erect cocks are inserted into large motorized onaholes. He is sweaty, stains showing on his shirt under his breasts and on his armpits. He says: "G-guys, stop donating so fast!! This s-stage is really ha, hard-"

Finally done working for the day/night... here's Aidan's back tats

snooze time
digital illustration of my OC Aidan, seen nude from the back. He's holding his hair up so you can see his upper back tattoo, two firey skulls with the text "LOVE AETERNAL". In the classic 'tramp stamp' location is a set of tattooed handlebars, with the words "SADDLE UP".

I've done some stuff with her, but not a ton - she was originally a one-off joke character, but I enjoyed drawing her so I kept doing it!
She's a meek civilian who gets drafted into a mech pilot program after she gets accidentally exposed to alien tech. Here's some establishing stuff~
Digital illustration of my OC Kimiko, naked and strapped into her mech's cockpit system. Her cock is stuck in a milking apparatus, and a huge dildo is in her ass. She is lit by various screens, including a red one that reads "PROSTATE STIMULATOR OFFLINE" and a blue one that says "MISSILES ARMED". An overlay showing her commander says: "Kimi! You've got to cum - now!" she replies: "I'm t-trying, commander!" and then she mutters "c'mon, you big stupid cock..." Digital Illustration of my OC Kimiko, shown in casual dress. Next to her is a scale illustration of her mech 'C17 Halberd' (though this design is a placeholder, I'm still learning how to draw mecha". There's a bunch of text here I can't pull from the CSP at the moment, but that info is all up on my toyhou.se profile of her. Digital illustration of my OC Kimiko, during her "activation event" where after exposure to an alien artifact, her DNA is rewritten to give her a huge dick. She is leaning on the counter of a bank teller station, her stomach stuffed full as she clutches her head, sweat on her face. From offscreen, someone says: "Kimi, what the hell?! the breakroom is a mess, did you eat EVERYONE's lunch?? that was a week's worth of food for the whole bank! get back here and clean this up!!" Kimi mutters weakly: "ah! aah! I'm s-ssorry, I'm burning up, I can't" Continuation of the last digital illustration of Kimiko during her activation event; this time her stomach is flatter, but a huge cock and balls have sprouted between her legs, cumming all over the bank as she clutches her cock with one hand. She has a dizzy, ecstatic look on her face. From offscreen, her coworker shrieks: "oh god whAT IS THAT!?!?"

Blue Prince is probably the greatest game I've ever loathed (affectionately), anyway I turned the Mechanarium into a twink
Digital illustration of a mechanical robot femboy, with rounded pecs, hips, and shoulders, and wide hips. His casing is a dark blue-grey, with blue glass panels in various places revealing layers of gears underneath. His genitals are a small set of balls, above which sits a thick gear, implying that it is a kind of flat chastity cage. He looks at the viewer in surprise, one hand near his face, two heart symbols floating next to his head. He says: "you re-rolled just so you could draft /me/? e-even though I'm locked?" For context, this is a gijinka of the Mechanarium room in the game Blue Prince, a mystical exploration game.

idk why I made this
edited screenshot from the in-development Legend of Zelda movie, where Benjamin Evan Ainsworth is looking somewhat to the right of the viewer. In the foreground I pasted in a Pot from Ocarina of Time, so that it appears he is looking at it. Above the pot in white lettering it says "DO IT." Is that the pot saying it? his inner voice? navi? who knows but it's gonna get thrown to the next county

while Kimiko canonically pilots her mech while naked, I felt like drawing a suit for her anyway just for fun~
Digital illustration of my OC Kimiko, a woman with big purple eyes and long brown hair, who has large breasts and an extremely large penis & balls. She is standing with legs at shoulder length, looking up shyly as she pushes a bit of hair behind her ear with one hand. She's wearing a mostly skintight flight suit, which is shades of powder blue except for her torso which is white, and her high-heel spikes which are black. Along the bulge of her penis, the acronym HYPER is written in shiny blue letters. The background is a zoomed-in, semitransparent image of her bulge. To the right, partially obscured by her restrained penis, is the text: "HIDAKA KIMIO pilot-in-training HYPER Weapon: HALBERD".

my half of an art trade with @sinxparadigm.bsky.social 's guy Ciel, out shopping and making a scene!
Digital illustration of sinxparadigm's OC Ciel, a purple-haired prince twink. He is dressed up in his white-and-grey outfit, however his absolutely gigantic cock and balls are hanging out, and the window on his chest is stuffed to bursting with his very big breasts. He is carrying shopping bags in the crook of each elbow, as he walks down a cobblestone path. The simple background implies a number of onlookers from within a building and on the street. Ciel has a grumpy expression as he looks to the side, thinking huffily to himself: "ugh... can't a prince go shopping without all that... staring? peasants."

she's coming along... (WIP)
digital illustration WIP of my OC Kimiko, focused on her face and seen from the top of her breasts up. She's wearing a mostly form-fitting blue suit, and is pulling her hair behind one ear as she blushes and looks bashfully to the side with a smile.

A ref sheet for my friend @gabethesqueak.bsky.social ! He wanted some funny business for Gabe~
Digital reference sheet illustration of my friend's OC Gabe, a Sylveon/Pachirisu pokesona. This is a clown version of Gabe; he has polka-dot patterns at the end of the coloring on his limbs, circles around his nipples and belly button, his tail stripe has some smaller additional stripes, and he has a purple clown nose. Three Clown Gabes are pictured - left to right is one of him facing forward, then one of him facing backward (with tail hidden), and then one of him facing forward but clothed. His outfit here is knee-length leather boots with white poms on the top of his feet, white-and-lavender striped arm gloves, stockings, and undies, and a black strap across his boobs which do nothing to hide his nipples but squish nicely. The piece is titled "Clown Gabe", and between Gabes 2 & 3 is the color palette, depicted as a bunch of multicolored ballons.

got the first snow where I'm at - which means I'm in my annual Twin Peaks Rewatch season! Here's a piece from a couple years ago of Mathis in the Red Room 🕺
digital illustration of my OC Mathis, in the iconic Red Room from the Twin Peaks series. the room is viewed from a wide shot, showing both the single black chair on the left and the two recliners on the right. Mathis is perched oddly on the lone chair, one foot on the black-and-white-zigzag-striped floor, the other on the chair cushion as he clutches the back of the chair, his other hand hidden behind him. He's wearing a sparkly black dress with a plunging neckline, one strap hanging off his arm, his red undies visible between his legs. His head is cocked to one side, as he stares at the viewer with an unsettlingly wide grin. The image is a bit fuzzy, as if being viewed on a CRT television broadcast. Yellow 90s-style subtitles read: "[oddly reverberating]"

today's Saturdoodle - a comfy elf!
digital illustration of an elven gal with enormous breasts. The piece is a bust, showing her huge boobs stuffed into her sweater, her arms resting atop them and holding a mug of hot chocolate. She is wearing a beanie with a pom-pom on the end. She is smiling gently at the viewer.

cropped screenshot of my PLZA game, showing the Alpha Goodra on my team that I named after Aidan. My character looks at the camera with a smile, while Aidan looms over. I wanted to get a picture of him at a cafe, but I literally cannot get his head in frame there lmao

GoodrAidan showing off his Great Balls
Digital illustration of "GoodrAidan", a version of my OC Aidan as a Goodra from pokemon. He's lounging on the stones of an alley, lifting up a leg to show off his genitals - including his big sloppy balls. Goodras are slime-dragons, so he's visibly wet and green slime leaks from his chin, his cock, and onto the ground around him. He looks at the viewer lasciviously, a heart symbol in his one visible pupil. I didn't put his tattoos on, they kinda looked a little weird to me.

Vaati, waiting for a hero
Digital illustration of Vaati from the Legend of Zelda games, in his human form and dressed in his "slutty Vaati" way that I do. He's reclining on a bed with pink sheets, hands behind his head, surrounded by rose petals. He has an erection, a red ribbon around his cock. His belly is slightly swollen and his womb tattoo is visible, implying an early pregnancy. As always, he looks grumpy despite his arousal, his visible eye glancing to the side.
