The Art of MadDoctor aka BlueApriicot

I discovered this artist only recently (see foot of post),  

but was impressed by his 'clean' style and interesting 'models'.

He's found a particularly attractive and real-looking (bleached?) blond for this image

 and it looks like he's being offered up as a sacrifice or plaything for a tentacled creature,

apparently in a dungeon or cellar, although his restraint is implied, not actually shown.

The captive's nicely tended hair and white underwear suggests he's been unexpectedly plucked from civilisation for this frightening assignment, but although he looks discomforted by the mouth invasion, there are some signs of enthusiasm germinating inside his Calvins. 

This creature stands back to entertain/torment it's fit-looking victim rather than encircling him with it's tentacles, which makes this story quite an unusual offering in the genre. 

It's something of a tradition in tentacle circles for artists to set up a victim, 'freeze' him and then let the creature have it's way with him, creating a series of near-identical frames to illustrate the process. It's a mystery to me why they don't publish them as .gifs. I usually select the frame I find most interesting as representative of such sets but I thought this fully-naked variant warranted inclusion alongside the underwear-clad one. You can find more from these series via the links at the end of this article

Shades of Zamok's gym here and that little connection lifts this image into S&M territory.

Another nicely modeled captive (apart from his haircut perhaps) with a suitably worried look.

That's probably enough to fuel most imaginations.

Dicks on sticks seem a bit Heath-Robinson and dangerous to me, but strangely the motorised version, lacking any obvious human control element, seems safer and for a bound man it's inherent unstoppability is much more telling as a domination technique.

I like the basic simplicity of this imagery, but the addition of the simplest of bare rooms as a background makes a surprising difference, introducing depth and a suitably sinister, isolating atmosphere.

That sense of  remorseless processing is invested in a far more powerful robot here. The tight (yet seemingly soft) bondage of both arms and doubled-back legs instills utter helplessness into the captive who is lifted high into the air with a single, simple, body clamp to receive penetration. 

It's a striking image which puts the captive and his plight at the forefront and does not really need the dildo for it's impact. There might easily be something more threatening in the room, behind us, just out of our sight - but not the captive's. 

This prisoner is less restricted in movement, but even more dwarfed by his captivity device.

It's a nice 'dangling' image in any context and even though the underwear is very simply rendered,

I for one appreciate him being allowed to keep it on. For now anyway.

This artist's penchant for innovation in tentacle lore continues with a highly unusual species which appear to be boned and jointed with equally refined tactile capabilities. 

Like the first example they are disinclined to encircle their prey (and possibly are incapable of it)

but his gritted teeth suggests he's still having a pretty unpleasant, invasive experience.

Their 'detachment' would make him feel more like a specimen than a living being.

He dangles helplessly above them while they reach up to attack him.

After his tormentors have had their fill of him, he hangs exhausted and seemingly bruised. 

Notice that he lost his hold on one of the hand grips now.
That weakening continues in the next image as his strength ebbs away.

This is one of the best of these images conveying great sense of isolation and helplessness.

That's reinforced by the victim's nudity and the empty void in which he is supended.
He's lost his grip completely now and with it the last semblance of any control. 

By resisting the temptation to spread his limbs wider,
the artist has created some nice body and buttock shaping

lengthening the body and accentuating the sense of him dangling in space. 

This image is constructed from photographs, but it has a similar simplicity to the renders above.
I have no idea what is being done to this man but the high-tech cock-sleeve is very erotic and it's ethereal, kryptonite-green 'spark' looks suitably daunting. The fact that he has to be strapped down for the treatment and has a look of awe on his face is explanation enough. The slightly raised far leg suggests he has the freedom to squirm a little for us, but I think I'd have opted for 'losing' it, so he looked more fully restrained.

I think this artist might produce a memorable 'Milking Factory' if he turned his hand to it.

I don't have a website for this artist. All the pictures have tumblr titles so I guess he's a casualty of their recent fit of corporate decency which has also hit Yahoo! Groups.

I got these examples from a post by Olaf at GMBA dated April 1st 2020 or thereabouts 

it had more in the same vein.
