deep into the waters...

YCH comm from a while ago for MissTiggeh!
An underwater scene where a merman tenderly holds a stunned elf girl from behind. Close-up alt of the same picture; the elf's clothes are now pulled away and the merman fondles her uncovered breasts and groin. Her expression is of overwhelming pleasure. The close-up shows only their top halves; they're probably having a blast under the cut.

A cropped preview of another version of the quoted image; a hint of Zephyr's bare erection can be seen.

(2024) sneaking into a holy place dressed as a nun and fucking everyone there isn't a halloween costume 🙄

[ #ismephyr ⋄ #nsfwart ⋄ #transmascnsfw ]
patron ask: what would Ismedhai's Halloween costume look like? Ismedhai (he/him), an incubus, disguises himself as a nun. He puts his finger to his lips, grinning towards the viewer. "It's our little secret... no one knows it's a costume yet." His other hand holds a crucifix pendant. He reveals to be wearing a strap-on under his garments, along with garterbelts in the shape of inverted crosses. The crucifix pendant turns out to also be inverted, and his demon tail is revealed as well. "Oh, don't act so surprised. I could *smell* your excitement around me." He rests his hand gently on someone's (drawn to be purposefully featureless) head, as they kneel before them, face turned towards their strap - as if receiving a blessing. "Bless you, my child", the demon says, eyes bright red with dark sclera.

(2024) yearning over text
#zephyatt
Patron ask: "if normal Hyatt had a dilemma, do you think he'd have the classic angel devil shoulder deal with Angel Hyatt and Demon Hyatt?" 00:12 AM; Hyatt lays in bed with his phone, sleepy and pining. He and Zephyr exchange texts: (Zephyr) Isn't it past your bedtime now Go sleep you goof (Hyatt) I'mm no sle3pyu Sleeky Slippery Silly (Zephyr) Course not A tiny Angel!Hyatt leans over Hyatt's shoulder, patting him on the head. "I think we talked to Zezé enough. Let's put the phone down and sleep before we get silly!" Hyatt is halfway through typing "I just missed talking to y-". Demon!Hyatt pops up on his other shoulder and whispers on his ear "Tell him you want him to be your first." "NO!!!", angel!Hyatt exclaims while falling off the other side. Meanwhile, Zephyr grins and chuckles while reading his phone while riding the subway. Hyatt's messages read: I just missed talkign to you'd like takeout vinegar Have me vanilla Canttt Gnight Zezé

(2023) I named this file "zecest incoming.png"

#ismephyr
Patron ask: hey Demon!Hyatt (Ismedhai), have you ever thought about taking other forms like Zephyr or possibly your original form Ismedhai shapeshifts into a much sluttier version of Zephyr and responds "I'm afraid 'original form' isn't in the roster... but I'm pleased to take on other requests." The real Zephyr shows up and gets up his face, annoyed. "You've shown off enough." "Oh, you're not impressed?", the demon teases with a grin, "I'm sure your precious little angel will appreciate this form-" "Want to take the form of minced meat?"

(2024) oh, please. Drop the act. 📿
#ismephyr
Exorcist AU Zephyr (a demon hunter) and Ismedhai (an incubus) stand extremely close to each other. Zephyr, much taller, stares down at Ismedhai with an unimpressed expression, while the incubus stares up at him with a smug grin - holding onto his cross necklace and pulling it towards himself. There's obvious tension in the air.

2023 art of my idol OC Hikarin being worked to the ground 💗

[ #hikarin ⋄ #nsfw ⋄ #nsfwart ⋄ #dubcon ]
cw dubcon Patreon request reads: "Dylan (the manager) is very busy making phone calls. Sure would be nice if Hikaru would warm up his cock for him while he had to call in for a meeting~ it's the least they can do to help relieve his stress!" Hikarin's manager grabs them by the hair as they kneel before him, his cock deep in their mouth while the idol sports a dulled expression, passively taking it in. The manager talks over the phone: "-and I trust that my idol will be treated with the utmost care and diligence on set." Next, the manager sits down nonchalantly while Hikarin rides him, covering their own mouth with their hand to hold back their grunts. They're half-dressed in a cute cheerleader uniform, and their expression is flushed and troubled. The manager continues his conversation: "Yes. We're both elated by Hikarin's participation in the feature. They have an extremely tight schedule, but we'll manage to fit in rehearsal for sure."

I'm gonna put it out there that there's a couple of rare explicit Nio sketches with interesting dialogue that I posted only on Patreon, before they even made their social media debut...

#ocnio
Closeup of Nio's cute tits. They smile cheekily. Nio grabs and sniffs onto a unidentified piece of clothing. Their other hand is somewhere lower.

2024 comic about my idol OC, Hikarin!

#hikarin
Patron ask: How did Hikarin get into being an idol? Do they like it, or is it just a job? Hikaru sits at home, hunching over a conversation with their manager via text on their phone. The manager's messages read: - I fixed next week's schedule. Rehearsal for the movie starts friday. I'm waking you up at five. Hikaru replies simply: - Okay The manager continues: - Btw, I was looking through old files and found your audition form. An image is attached; a document with a picture of a younger Hikaru in school uniform. Their hair and eyes are brown, and they sport an upbeat expression towards the camera. The manager's texts are placed beside the picture: "That's the gem that caught my eye. Look how young and cute you used to be." Current Hikaru stares down at their phone with an empty expression- their hair is now a soft pink, their eyes are blue, and the spark is gone. The next text is also juxtapositioned: "I miss the time when you were excitable." A close-up of the document reveals part of the questionnaire. "Q: Why do you want to become an idol?" "A: I never thought about being an idol before - I think singing is fun, and I was told I have a talent to charm people's hearts! It feels good to be appreciated and bring joy to those around me, so I'd be happy to keep doing that. (...) strong points and talents? (...) guitar. I'm a hard worker and (...) The last text from manager reads: "But I guess it's inevitable after you peak." A pop-up message reads "Delete image from your gallery?" "Sucessfully deleted."

An underwater scene where a siren embraces a pirate girl from behind, feeling up her breasts and lower stomach; the latter indulges in it, letting go of her sword.

part 2 - so that's where they got that 'dress'...

[ #ocnio ⋄ #weifeng ⋄ #oc ⋄ #OCsky]
Nio poses in front of a mirror, in the same manner as the first post on this thread, wearing the revealing "dress". They cackle triumphantly: "Ohohoho! I'm so hot!! I'm the hottest oracle this world has seen!!" Later, Nio and Weifeng sit in tea break during training. Weifeng stares suspiciously at Nio, who drinks their tea with an undisturbed expression. "I'm going to ask only once:", he says, "do you have anything to do with the dining hall's curtains disappearing?" "Nope." "Are you sure?" "You said you'd ask only once."
