Concept: You swap minds with your hunky beefcake pokemon, then the pokemon in your body deposits you into computer purgatory for the rest of time.

A comic page showing a pokemon trainer and a machoke, the muscle pokemon, agreeing to swap bodies. Panel 1. The trainer and the machoke are shaking hands. The trainer says "Just for a day. I'll get to be a biig muscular pokemon and you get to be a human being!". The machoke says "choke!". Panel 2. The trainer is sat in a chair next to a pokemon trade machine, a tube above their head connected to a computer with another tube hovering above a pokeball. Panel 3. A close up of the computer screen showing the trade in progress, a silhouette of the pokemon and a silhouette of the human. Panel 4. The trade worked. The human is flexing his arms, now with the machoke brain driving, he says "woah! human arms. feels kind of weak but I can fix that". Panel 5. The trainer is stood in front of a computer, the computer says "Are you sure you want to deposit 'machoke?'". the tranier says "i think i'll keep it". they are depositing the pokeball with machoke inside of it into the computer system.

What if when you released a Pokemon from a Pokeball, it left residual dna data in the Pokeball... so you could throw it an an unsuspecting pal and get yourself a nice reminder of that pokemon you just set free.

Whilst I'm on my donkey hype here is a commission I grabbed from @werewolfaboo.bsky.social back in 2020 of my bunny going donkey.
A rabbit and a donkey are pretty similar animals with the long ears, you just have to yank out the muzzle a bit and shrink the brain down.

You trade your BIG IQ with a jock so they can pass their finals, in return you get to 'borrow' their BIG MUSCLES until after the test. (the machine is obviously extremely fragile)

A homage to one of my fave fetish arts by @lieutpride.bsky.social (piece in comments)
A 3 panel comic showing a nerd and a jock swapping traits through a machine. Panel 1. The naked tall muscle jock is stood next to a skinny short nerd, they are both wearing fragile thin cloth head bands connected to a machine labelled as 'Jock experience and skills transfermeter'. The jock asks: "Dude... this thing is really itchy!" The nerd says: "Don't break it or this thing won't work!" The jock continues: "So you'll give me your smarts so I can pass my tests? But why do I have to be naked for this?" The nerd responds: "Science". Panel 2. A silhouette of the machine in action, the two men morphing in size. Panel 3. The two men have switched heights, muscles and dick sizes. The nerd is now extremely tall, flexing his big muscles, and his huge new dick is swinging out in front of him. The jock has shrunk dramatically in size to be as skinny as the nerd was. The jock screams out pointing at his dick "Bro you didn't say anything about taking my freaking dick!". The nerd, now much dumber is tearing the headband off his head "Dude this thing is really itchy...".

So you caught a beefcake pokemon so they would give you muscle shows on demand, BUT the pokemon refuses to do as you command?
Solution! Collect all the badges in your region so ALL POKEMON will obey you, irrelevant of what it is you demand.

A 4 panel hypnosis themed pokemon comic. Panel 1. A pokemon trainer is pointing at a machoke, the muscle pokemon, and ordering him. The machoke has his arms crossed and refuses to obey. The trainer says: Alright jugs, I want you to bounce your tits for me right now. The machoke replies: Choke (in defiance) Panel 2. The trainer has opened up his vest to show 8 badges hidden inside. The trainer says: I have all eight gym badges. So let's try this again. Jugs, use pec bounce!. Panel 3. The machokes eyes have turned to spirals, his chest is pulsating with energy, he is trying to resist, he screams out "Ma-choke!". Panel 4. The machoke still spiral eyed is flexing both his arms and bouncing each of this tits with a big smile, unable to stop. The text says "Jugs used pec bounce! It was super effective".

I am happy to see that people have embraced the idea of being a NERD.
Even @spacepupsilver.com is getting in on the action.
Everyone should be a NERD, and enjoy some FEET, and FEET FEET FEET FEET...

I've been on a huge donkey tf hyper fixation recently.
I draw a ton of donkey stuff that I rarely tend to post publicly but I'd definitely call it one of my top 5 kinks, so making a conscious effort to share more of it.
Maybe I'll plant a new kink in your head 🫏🧠🥕

The man has won the prize of turning into a donkey. Label reads: Pleasure Island Casino, Everyone's a winner! Disclaimer: everyones a winner claim is based on the assumption most people turning into a dumb animal and no longer needing to care nor understand human issues like bills, politics and basic social skills would be considered a fabulous prize.

Had the urge to draw out my "OC's" this morning.
Generally each piece I do is just an exploration of a theme, but recently I'm doing some recurring characters a bit more.
Mostly I'm just a thirsty boy for a 'trigger/trope' to frame kinks within.
An 8 panel chart showing different spacepupsilver characters. Panel 1. Sex dogs. 3 rubber human puppies are crowded in the square looking confused, one of them is holding a power drill. One dog says "We appear to be trapped in a cube". Another dog replies "What If I drilled a hole? Then we'd be trapped in a glory hole?". Panel 2. Monkey's Paw. a twink holds up a blue monkeys paw with a medal around his wrist. He says "let's celebrate this inanimate decapitated hand!". Panel 3. Alien. A thick juicy rubber alien with a raygun stands saying "Pew, pew, pew". Panel 4. Boy frotteur and Timmy. a man in a jumper stands next to a twink in a jockstrap. The twink asks "Mr frotteur, are we an example?". The jumper man responds "You may remember us from other examples such as the dangers of gooning!". Panel 5. Coachman (donkeys). A man in a waistcoat and top hat smiles standing above a twink transforming into a donkey. The coachman says "Its not animal abuse if the animals were formerly human. It's regular abuse. And that an be totally ignored in a court of law". Panel 6. Genie. A blue genie in a muir cap is floating with his arms crossed. he says "Wish granted". Panel 7. Miscellaneous twink. A skinny twink in a jockstrap stands and ask the genie in the last panel "I wish i had juicy fat pecs". Panel 8. generic himbo. A muscular himbo stands. He says "i'm him but stronger!" pointing at the twink from panel 7.

On one side a human puppy in a rubber suit is on it's knees with a chastity cage dripping cum, on the other side of the image is a leather daddy flexing his arms. Their minds have been switched. The puppy inside the leather daddy says: So 'Sir' what do you think of your body from this angle? The daddy inside the puppies body is twitching hard in his cage and says: Holy fucking crap I'm so fucking gorgeous. Are you this feral looking at me all the time? I need you to fuck me. Right now.

A genie wish erotic comic showing two boyfriends arguing whilst a genie turns one of them into a pair of underwear. Panel 1. A naked muscular man is holding a genies lamp with a genie hovering above it, next to him a slimmer man in a green jockstrap looks annoyed. Naked man says "I wish my boyfriend would spend some time with me. He's always gaming at 2am instead of fucking me". Jockstrap man replies "I want to spend time wiith you but you're always at the gym inn the day when I'm not gaming!". Panel 2. The genie points his finger at the jockstrap man and pulls him to his knees and through the legs of the naked man shouting out "extreme couples therapy? Wish Granted!". Panel 3. The jockstrap man is forced to grab his ankles whilst he lies on the floor. The naked man asks "What are you doing to him?. The naked man says "I feel hollow?!". His jockstrap fabric seems to be spreading across his body. Panel 4. The jockstrap man is visibly warping to become a jockstrap himself. The genie says "You wanted to spend time together, I'm turning him into your new favourite jockstrap!". The naked man looks panicked and says "That's not what I asked for!". Panel 5. The genie zaps the naked mans brains and both the genie and the mans eyes glow blue. The jockstrap transformation is almost completed, the naked mans face is now the only piece of flesh left on him, the rest of his body a regular jockstrap. The genie says "Freebie for you to calm you down a bit. He's ALWAYS been your favourite jockstrap". The naked man looks dazed and is brainwashed to agree "Bro... I've had this jock for years...". The jockstrap screams out "No! Stop! Help me!". Panel 6. The naked man is now wearing a jockstrap, smiling cockily. The genie is blowinig smoke from his finger from doing his magic. The genie asks "So master, what do you want to wish for next?". The man responds "Bigger dick, obviously!". The genie smiles "Functional size? furry size? or fantasy size". Ignoring what just occurred.

Happy Birthday @pigletstorm.bsky.social sending psychic energy to make your pecs triple in size.
An erotic illustration of a man-cow hybrid on his knees, he has long cow ears, cow feet and a tail, cow markings are over his arms and legs. His arms are in arm binders, restraining them behind his back. His ankles are in heavy iron shackles and his pecs each have a large pod over them with a tap, to pour out pec milk. His dick is in a chastity cage that is dripping small drops of cum into a tube marked Diet Milk. A dildo is ramming his throw. An electro dildo is zapping his asshole. A headset is over his eyes. He is being utterly milked in a bondage way. To the side a rubber puppy is on the ground holding his knees in his hands and addressing you, the audience. He says "Now this may seem strange to you... but can you explain to me how the fuck you milk an almond?"
