I literally made this guy like 2 years ago for a solo run of BG3 as a collaborative joke with friends, and it just ended up being Thanos if he was a deep gnome, and their name is Banos.

As time has gone on, I've unironically started really appreciating this purple freak of a parody. That's my guy.
A purple deep gnome named Banos from Baldur's Gate 3 resembling Thanos. He has orange hair that's spiked up in the center and sides combed back. And has mutton chops that's also orange. He's looking at someone with a cocked eyebrow.

Since people were *very* interested in an aggressive take of what Barbertos would be like in the bedroom. Ended up doing a really fast off the cuff sketch the other day, and brought back an old OC, Klaus, for the job.

#FurryArt #NSFWArt #NSFWGay #FurryNSFW #BirdOC #Sketch #DigitalArt #UGNart
Barbertos, a large fat great horned owl, in a fit of anger, aggressively fucking Klaus, a thin framed kookaburra, into the ground (because it's a rough sketch, it's supposed to be interpreted as a bed). Klaus is nearly face down with his rear end lifted up some, as Barbertos is squatting, gripping Klaus' waistline tightly as he pounds him hard an fast. His expression is full blown mad and that of one almost screaming, while Klaus' writhes in overstimulated pleasure and pain, gripping the sheets around him tightly. Barbertos' belly rest over Klaus' ass and over a third of his back, his feathers puffed up and bits of it floating off of him. Text reads: Barbertos: Didn't ya learn ANY DAMN MANNERS? Ain't no ounce of RESPECT given, just 'cuse you EXPECTED to be OWED for somethin' you DEMAND?! Reckon I slam some common sense into that pompus beak of yours!! Klaus: "Ouh- Arg- Shit!! I-I'm- ah- Fuck~"

I may draw him sexy and desirable, but he is a barbarian at the end of the day, and I must reinforce that every now and then cause it's cool as fuck.
A rough head sketch of Barbertos, a large great horned owl, looking more fluffed up and with a piercing raged expression.

Also here's one with all the doodles on one page, just for ya'll lol. Also the sketch page cause I really like how that looks on it's own too.

#hndr_fa #HundredLine #NSFW #NSFWart #DoodlePage #illustration #Sketch #DigitalArt #UGNart
Full page from original post (https://bsky.app/profile/undergreysnest.bsky.social/post/3m44ldnf5rk2g) Sirei and Nigou, white egg-shaped ghost looking robots, having sex in various positions, too many to properly describe in proper detail. Nigou is put through a "training regimen" to learn how to properly peg with a strapon. The sex positions are as followed: Reversed cowgirl, doggy style (Sirei on top only for this one), slider glider, on back with his legs propped up, against the wall, Sirei sucking Nigou's strap clean with a back and front facing view point, and normal cowgirl. The final doodle is of Sirei congratulating Nigou on making him cum 100 times with satisfaction coming from both of them. Text reads Reverse Cowgirl Nigou: "S-sir, you're quite heavy..." Sirei: "Come on! No matter the weight of your comrade, you have to ACT! Work that pelvis! Nigou: "Rah, yes, s-sir! Doggy Style Sirei: "Oh my god are you really THAT BAD?! You have to angle your attack to find anyone's weak point. You get ONE demonstration! TAKE NOTES!! Nigou: "Mmph-! Ah- mrph- Ah, ah- Sir!" Slider Glider Nigou: "I-I'm picking up the pace Sirei, sir." Sirei: "About time Nigo- ! Oh..." On Back Sirei: "Your training's- urgh- paying off! Good progress!" Against the Wall Sirei: "Aurghh.... At ease, Soldier. I came like 3 times... (Gonna need to start building MY endurance) Nigou: "Aye-Aye! Thank you, Honorable Sirei!" Sucking the Strap Sirei: "Yeehaaaw!! THAT'S the stuff! Hope you've charged yourself last night Nigou, cause I'm riding until this battery runs dry!: Nigou: Gulp Cowgirl Nigou: "Umm...is this part of the training regimen? (Seems like there's a better way to clean this, but orders are orders) Sirei: "slurp No, but we can't have urp ah- unsanitary equipment for future sessions. Congrats Sirei: "Well done, Nigou! My ass is thoroughly sore, and you passed your training! Making me cum 100 times; the enemy doesn't stand a chance! Nigou: "Hooray! Thank you Honorable Sirei, Sir!" The original sketch page of the finished page. The description is the same as the previous image, except here, certain elements can be seen like dildo penetration and body/facial detail normally hidden in the final piece.

This entire doodle page was directly inspired by discovering my previous Sirei/Nigou piece got uploaded to R34 and saw these comments, and I understood the assignment.
Screenshot from a r34 post of my own previous work cropped out showing the comments Text reads: 1st comment: No way bro 2nd Comment: I haven't seen every ending, but I feel this would actually happen in the game 3rd comment: ^ Bro didn't find the Sirei Backshots route

The secret "Sirei's Backshots Route" is in full swing! Nigou's got his work cut out for him cause damn, Sirei is a demanding commanding officer! After this, Nigou will be a certified prostate smasher 🫡

#hndr_fa #HundredLine #NSFW #NSFWart #DigitalArt #UGNart
In the first one in the top left, Sirei is getting pegged doing a reverse cowgirl, riding Nigou with experience; hand on his hip and holding his hat in place from falling. He's turned looking back at Nigou with a frustrated expression, expecting better. Nigou is struggling to thrust or keep up any kind of rhythm, eyes shut tight. 2nd drawing in the bottom left has Sirei taking charge, going doggy style on Nigou. Coming to a boiling point, laying down pipe at Nigou for his failing performance. Using this as a learning experience and telling him he gets one demonstration. Sirei has an angering expression, holding up a figure in the air and holding onto Nigou's butt. Nigou looking embarrassed. pleasured and taken aback by Sirei's performance being the best of the best. Text reads in the first panel Nigou: "S-sir, you're quite heavy..." Sirei: "Come on! No matter the weight of your comrade, you have to ACT! Work that pelvis! Nigou: "Rah, yes, s-sir! Text from the 2nd image Sirei: "Oh my god are you really THAT BAD?! You have to angle your attack to find anyone's weak point. You get ONE demonstration! TAKE NOTES!! Nigou: "Mmph-! Ah- mrph- Ah, ah- Sir!" A set of 3 drawings of Sirei and Nigou in several sex positions as the training continues. In the top left image, Sirei continues to be pegged but in the slider glider position, in a rather relaxed, bored state before Nigou picks up the speed and starts hitting the right spots. His penis hangs semi erect, dripping a small amount of precum. Sirei props his head up with one arm and another resting along the floor, looking surprised. Nigou has one of Sirei's legs hooked over his shoulder and holding on for leverage as he thrusts with more force and speed, looking more determined. 2nd image in the top right coming from a pseudo POV from Nigou as Sirei lays back, pulling up his legs letting Nigou get in there as easily as possible. He looks a lot more pleasured, blushing, as more precum drips onto his stomach and further down his erect dick. 3rd image on the bottom has the two standing near what would be a wall (not drawn, it's implied), during a post multi orgasm sex session. Sirei is absolutely exhausted, bent over, face resting against the wall, and one hand on it as well for support. He exclaims Nigou did a great job, while Nigou himself looks mighty proud and gives a salute. Cum is splattered against the wall and coating the floor beneath Sirei. Text Reads from the first image Nigou: "I-I'm picking up the pace Sirei, sir." Sirei: "About time Nigo- ! Oh..." Text from the 2nd image Sirei: "Your training's- urgh- paying off! Good progress!" Text from the 3rd image Sirei: "Aurghh.... At ease, Soldier. I came like 3 times... (Gonna need to start building MY endurance) Nigou: "Aye-Aye! Thank you, Honorable Sirei!" Another set of 3 images of Sirei and Nigou. 1st image on the top, Sirei is riding Nigou in the normal cowgirl position with great enthusiasm, really starting to enjoy the anal orgasms. He rides him like a cowboy, waving his hat around as he shoots ropes of cum past Nigou's head on the ground behind him. He has Nigou's legs locked around his, taking full control as Nigou grips the ground with a heavy flustered look as Sirei has no plans of stopping anytime soon. 2nd image in the bottom left has a post sex session of Sirei laying on his side but propping himself up to sucking off Nigou's strapon clean. His ass is dripping full of lube. Nigou looks and sounds more confused about whether this is even part of the training as he feels its unnecessary while Sirei reassures him that while it isn't, it's better to be clean than unsanitary. An alternative perspective showing Sirei fully enjoying cleaning and polishing off Nigou's dildo with a rather submissive expression. 3rd Image in the bottom right shows Sirei congratulating Nigou on successfully making him cum 100 times while struggling to stand and using his cane to balance and hold himself up, looking pleased and content. Nigou is thrilled and excited for passing, pacing in place and being giddy. Text from the first image Sirei: "Yeehaaaw!! THAT'S the stuff! Hope you've charged yourself last night Nigou, cause I'm riding until this battery runs dry!: Nigou: Gulp Text from the 2nd image Nigou: "Umm...is this part of the training regimen? (Seems like there's a better way to clean this, but orders are orders) Sirei: "slurp No, but we can't have urp ah- unsanitary equipment for future sessions. Text from the 3rd image Sirei: "Well done, Nigou! My ass is thoroughly sore, and you passed your training! Making me cum 100 times; the enemy doesn't stand a chance! Nigou: "Hooray! Thank you Honorable Sirei, Sir!"

Was doodling stuff the other day, and I kept thinking about a pseudo-yoga pose for Barbertos. Not perfect, but still, I liked how it eventually formed. It's been a minute, I've missed him. Looks like he's invited ya too.

Two ghost like looking robots having sex cowgirl position. Sirei riding Nigou's strapon with great enthusiasm like he's riding a bull and cumming ropes. Nigou on the other hand, nervous at the prospect of being riden longer than anticipated. Text reads Sirei: "Yeeehaaaaw!! THAT'S the stuff! Hope you've charged yourself last night Nigou, cause I'm riding until this battery runs dry!" Nigou: *Gulp*

Jevil using his spring neck, extends it out to get a full view of Seam doing his work with a hungering expression, tongue out and all while Seam looking displeased of his jester tricks.

There comes a point where you're so desperate to sound like you're right about something that is so easily disprovable, that you're no longer scraping the bottom of the barrel. You're peeling the wooden planks of any moisture it has to make up some of the most cartoonishly dumb reasons imaginable.

Big Z, a large fat emperor penguin having a threesome with a smaller grey bird (my oc), and a red otter, Otis (belongs to @thealfieinc.bsky.social). Big Z sits on top of Otis, burying most of his smaller body underneath him, pampering the otter with his talon flippers; one on his cheek and the other squishing the top of his snout. Otis is completely smitten and relishing in the pampering with a goofy smile and tongue sticking out. His hands grabbing and holding onto Z's flipper and fat legs, and his tail wrapped around Z's leg as well while the penguin holds onto it for partial leverage. Big Z himself is leaning his head back some to hold the grey bird in his mouth with a wing holding him in place, as he rims him with a fat tongue. Saliva covering the bird's rear end and drooling down Z's beak and fat chin. The grey bird is in pure pleasure, eyes shut tight as he feels the tongue doing its thing. His own talons clenched and a wing holding onto Big Z's head for support. Big Z's own humanoid cock leaking pre, getting partially caught in the folds of his foreskin. The background is of a beach with bendy looking palm trees and lush bushes. The ocean washes up besides the 3, lighting off partial reflections onto their fur. A mountain in the distance covers a peaking sun lighting up the scene.

Big Z, or Zeke, a large, fat emperor penguin laying on top of a smaller male bird in bed, slamming his big cock into him in. Precum is lathered across Z's dick, leaving a shininess to it. Big Z has one foot on the ground, standing on his talon toes, while the other rests a bent knee on a mattress, talons curled up in pleasure. His back arched, with his head craned up towards the sky with a face of intense pleasure. The small bird's own cock leaks onto the ground while his talons curl and stretch in different ways. Subtle steam clouds emanate around them from the intense love making. Same as the previous image, except Big Z and the grey bird are cumming hard. Cum torrents out of his ass as he continues to pump/slam into him and other bits of cum/precum stick to and fly off Z's own balls. The grey bird cums on the ground hands free. A solo alt of Big Z/Zeke laying on his stomach and on his knees tucked in, propping his head with his flipper, resting his fat chin on it while looking back. His balls rest on the ground with his anus exposed. Big Z/Zeke laying on his stomach and on his knees tucked in, propping his head with his flipper, resting his fat chin on it while looking back at the smaller grey bird (my oc) with a smile and half lidded eyes, entertained by the treatment. The grey bird has a good bit of his beak deep in Z's butt, rimming him and lapping him up.
