It’s my birthday. Also, @moosetracks80085.com has completed another excellent commission! It’s a cover piece for one of my oldest and most well known stories, A Burden On Your Chest. Read the story on SwellTales: swelltales.com/Home/ReadTal...

Cover for an expansion erotica story called A Burden On Your Chest. A woman with yoga ball sized breasts is pushed by a woman with an enormous butt. Meanwhile, a sinister old woman waves a finger in the air at them as if casting a spell.

@moosetracks80085.bsky.social has been drawing up a storm and now, another gorgeous commission is complete. This is based on a scene from The Milk of Human Desire, my breast expansion/lactation story about a deal with a devil.

Image of a woman with cow horns and gigantic, lap-filling, naked breasts sitting in a living room surrounded by a group of weirdly entranced people. She lactates while one of them collects her milk in a cup.

Now that I have completed half a novel, I’m taking a break from writing and catching up on neglected tasks. I have new art by @moosetracks80085.bsky.social to share, based on a scene from my hourglass expansion story, Thick As A Thief. Read the story here: swelltales.com/Home/ReadTal...

Illustration from TrebleCleffy’s Thick As A Thief. Main character Laverna’s boobs are popping in a skin-tight red sweater while she robs an apparel shop while wearing a reflective Halloween mask. The store clerk recoils in fear in the mask’s reflection.

@moosetracks80085.bsky.social has created another beautiful illustration of an old story of mine. This is from 2016’s Nora, Nourishing.

Nora, who has been charmed by a witch to grow humongous, lactating breasts gets help from her boyfriend Theo as she expresses her milk into a sink basin.

Is there anyone out there who hasn’t played the Mika Mod (sprites by Oct-Oppai, writing by me) who is interested/curious? Is there anything we could do to convince you to give it a try?
