He looks so calm and innocent, but having a huge dick and an insanely high sex drive is the hottest thing ever!!
Well—honestly, just having a huge dick is already erotic enough.
This version of Joy is still before he gets hard, so that’s his pre-erection size.
By the way, Joy is built with a huge dick, a lot of cum, fast recovery, and the stamina to go multiple ro...

This is a Dragon ○ Monster ○ fan-made (derivative) book that I published back in 2012.
Looking back at it, I thought, “Oh, this is actually pretty cute,” so if you’ve never seen it before, I’d be happy if you took a look 😊

Happy New Year!
I hope this year treats you well too.
I’ve put together an illustration book on BOOTH, compiling drawings I posted on support platforms and X from 2022 to 2025.
There aren’t any special newly drawn pieces, but if it sounds interesting to you, I’d be really happy if you checked it out!

Thank you all for your support throughout this year.
This year was truly full of many things—both good and bad—and it felt like a turning point for me.
I hope that next year will be filled with many good things, and I’ll keep doing my best moving forward.
I also want to put even more effort into my comics.
Thanks to all of you, I feel like I can end this year in good spi...

This is the first installment of the Love Maintenance series.
I’ve gained a lot of new followers, so this comic explains what Tom & Ena are all about.
These characters originally came from a one-shot manga I drew 12 years ago (2013).
People told me they liked Tom, which led to the series continuing.
Since then, I’ve added more...

Happy winter solstice, and Merry Christmas~!
And an announcement:
I’m planning to release my 4th illustration collection in January,
covering works from December 2022 to December 2025, including the illustrations posted this time.
The title will be:

Tom is a horny guy, so he wants to have lots of sex with Ena. He loves penetrating, knows how to use his ass, and can even force semen out through his anus — basically, tokoroten.

I thought "when was the last time I posted?" and it turns out it's been since July... I'm really, really sorry for being so slow with the smut 😭
Whenever I start overthinking "what kind of erotic scene should I draw next," my brain just goes completely blank... I'll keep going at my own pace again...!
I really love seeing characters in suits.
There’s something about someone who usually dresses casually suddenly looking sharp and formal—that contrast is irresistible to me.
A slightly higher resolution than the one on Twitter.
Sorry I couldn’t make any extra variations this time.
I’ve been drawing Joy so much lately, so it was really fun to draw Tom again after a while.
And… I just realized I haven’t drawn Ena even once this year. 😅
(I messed up… It's way too big…
I’m interested… but there’s no way I could handle something like this…
But people say it feels good once you can do it… ughhhh…)
Maybe this is before I can even do tokoroten (anal ejaculation). 🍄🥛💦
Joy-san has a huge dick.
Guys who have a big dick and are still curious about using their ass are...
”Just let me lean on you a little…
I’m craving some warm skin tonight…💦”
That’s the kind of fantasy I’ve been having.
Tom and Joy are friends—they’re not in a sexual relationship or anything like that.
Tom wouldn’t go that far since Ena is important to him… but he would probably let Joy touch him or hold him close.
If the two of them were ...

I’ve been drawing a lot of a Saint Bernard beastman character recently, named Joyful・Joyful.
I still don’t really know exactly what kind of person he is yet,
but I feel like he’s someone who expresses “I love you” a lot — that’s the kind of warmth I sense when I draw him.
It’s been such a joy to work on him.

Joy gets totally worn out in the sauna, probably because of his long fur.
Tom isn’t really good with the heat either, but I’m sure he’d love saunas.
Saunas really are great, aren’t they?
Around last year a friend invited me to properly try out a sauna, and since then I’ve come to really enjoy how amazing it feels to sweat it all out.
I haven’t experienced the famous ...

Thank you for waiting! The adult scenes will start from here.
However, since drawing explicit content takes quite a bit of time, I apologize in advance… I’d really appreciate it if you could wait patiently. 😭
I've been drawing as usual, but lately I've been really enjoying coloring by hand with traditional media, and I’ve kind of been focusing more on that.
I’m pretty happy with how the girl in the kimono turned out—I think I drew her well. (She’s not Yuki-chan.)
That said, I know I need to keep making progress on the manga, too.
And this time... Tom has finally turned into...

I've been really enjoying analog coloring lately, and I've been drawing as practice.
I'm practicing coloring with Copic markers and transparent watercolor.
I'm still just starting out, so I don't have much knowledge or technique yet, but I'm going to keep working hard so I can color more beautifully in the future!
Here are two new pages of the comic.
I originally wrote the dialogue for these scenes, but it didn’t feel quite right. I spent about three days going back and forth before finally settling on this version.
Even now, I’m still not sure if it really feels right to me.
Just like last time, these kinds of exchanges are tough because they really bring out the character’s inner emotion...
The belt wrapping under the crotch is super sexy and really nice, right? (●´ω｀●)
The logo was made by ChatGPT-kun!
Also, I was able to make an acrylic keychain of the previous illustration on BOOTH, so if anyone's interested, please take a look! 😆

I think the side slits on traditional Japanese hakama are kind of sexy. Normally, they’re covered by an overcoat, but when that’s missing, the glimpse you get—almost like they’re not wearing anything underneath—has a really erotic vibe. (●´ω｀●) I’d like to finish it in the style of a gacha game character illustration.

From choosing the right colors to the actual techniques, I still have a lot to learn and practice.
But painting with traditional watercolor is a lot of fun,...
