You're gonna tell me, the artist who's focus is mainly breasts, is late to posting the next theme, that of which is breast focused. You'd be 100% correct.

My characters, Rose (1), Lily (2), Ash (3), Iris (4) sharing a close moment with each other. Rose is kneeling, with an erection, hugging Lily's side while resting her head on Lily's breasts, her eyes stare longingly at Lily. Lily is back to back wit ash, holding hands. Her tail wraps around and rests under Ash's right breast. Lily's head is cocked to the side, resting it on Ash's horns. She gazes at the camera with bedroom eyes. Ash is looking at the camera, trying her best to put on a decent smile. Iris is to Ash's right, leaning out while staring directly at Ash's breasts, with a look of satisfaction. Her hand also rests on Ash's leg. My characters, Rose (1), Lily (2), Ash (3), Iris (4) sharing a close moment with each other.

I got stuck on this one, I won't lie. Anytime I tried thinking of something #submissive, breedable kept popping into my head. I wonder why 🤔

Ended up doing two 'cause I wasn't settled on the first one.

Alder (L) and Ash (R) fucking real hard. Ash is pegging Alder, suspending them up into the air, Alder resting on her lap. Her tail is wrapped around Alder's leg. She and Alder both have a hand on Alder's penis, which is blasting rope out above Alder's chest. There is a few lines of cum on Alder's chest, and some leaking out from below their ass. Rose (L) giving Ash (R) a tit fuck. Ash is resting on Rose's torso. Her hands grip Rose's large breasts with her enormous cock resting between them, cum leaking out the tip. Her balls are squished between Rose's torso and Ash's penis. Rose has a delighted look on her face, with a decent amount of cum dripping down her chin and face.

Only the people here from the beginning will recognize what the next project is, a remake with new models.

I have but one announcement, Ash's rework is finally done. She was what, my 3rd or 4th character I've ever made? Earliest file I can find is like 2021, what a difference 4 years makes. I'm kinda teary eyed over here like wtf 😭
Ash circa 2021. Not of very high quality. A Succubus wuth semi-long black hair, and 4 horns protruding very far from her head. She looks at the screen with a blank expression. The irises of her eyes are white and blue. Ash, 2025. Her model has received a much needed rework and upgrade. She stands against a black background illuminated by a purple glow. Her irises are now purple and glow very brightly. She still has the same horns as before, but they have been brought to a much more reasonable size. She stand with one hand covering her breasts, the other flipping of the camera. She has a slight smirk.

My two characters floating in a dark abyss. Alder is on top, their tits in Iris's face. Iris is holding her right breast up to Alder's mouth who's seductively looking at the camera with their mouth open ready to suck on Iris's nipple. Iris has her eyes closed and her tongue out a very short distance from Alders nipple. A blue light washes over Alder's face as does a light teal light washes over Iris's A dark night outside with both Iris and Alder. Iris is wearing bronze chain mail and pauldrons while she is giving Alder a blowjob, her breasts just barely in view. Her lips softly suck on the tip of Adler's erect penis that pokes out from under their tunic. Alder has now ejaculated, bulging Iris's cheeks while spilling cum down their erect member. Two large dribbles hang from the mess. Iris's magic tendrils wrap around Alder's thigh and work their way up Alder's body, one wresting just under the skirt of their tunic, and another working its way up their chest and entering Alder's mouth. To the left behind Iris rests the silhouette of a tree and a railing made of brick. Alder rests propped up against a brick wall, while the glow of several fires illuminate the background. My character Pastel, a succubus, resting against a wine rack. A few bottles fill the rack behind her, while just above her head, one of the bottles is uncorked and leaking a blue glowing liquid. The small amount of blue liquid has dissipated. Her breasts have expanded alot more, now the size of her torso x2. She is wearing a black skirt with blue trim and glasses. The tip of her horns and her eyes glow a light white. The background is a wine cellar lit up by a singular hanging fire, large bricks adorn the hallway and sides of the wine rack. Long timbers makeup the bracing of the roof and several wine barrels can be seen on the left hand side. Alder sitting in a dark room that fades into a stary night. Three candles cast an orange glow over their massive breasts. Their large dick pokes out from under their tits, awash in a dim blue light.

My personal site is coming along well. I figured its time to show off some of it. All images are server-side, and are automatically rescaled for the thumbnails. There is still a lot of functionality missing but for the most part but it works and works decently well.

Lily and Alder sharing a moment in a bathroom. A window is open in the background, revealing a moonlit sky draped in blue. Two major clouds are prominent, a tree, the stars and the open window. Lily rests on the counter made of a blue granite, a few towels and bottles are visible. A mirror reflects nothing of importance behind her. Two lamps dangle above them, one lit a light orange, the other a light purple. Alder grips Lily's thigh while squeezing her left tit. They both have a slight smug grin looking each other in the eyes.

I need help testing something. What color are the lights above them and what color do you see for the sky-box on the right? There are no wrong answers, just looking to see what color gambit is more prevalent among screens.

They don't really get many intruders in their Palace. It doesn't stop Iris from practicing her skills with the guards every now and then. In this case, she takes more pride in showing it off to the denizens.
