I want to tease and milk you until you can't hold back, and then watch you struggle from the overstimulation.

I really like it when cute characters are drawn with half closed eyes and a slight frown or uninterested expression. Especially as they're sexually pleasing someone. Does anyone know of a good English word for this?

I've been very bad at responding and commenting lately. Sorry about that.

Whenever I draw NSFW I often can't resist touching myself and it severely limits how much I'm able to get done...

I was cleaning my PVC suit and closed the zipper while it was turned inside out, but one of the sliders got stuck while it was fully closed and I struggled with it for over half and hour until I finally came to the conclusion that I had to sacrifice the slider to get it open.

I haven't posted anything in a long time... I have finally began to draw again though, after many months of nothing.

What's up with those accounts on twitter that only post about selling gear and have very random (probably stolen) pictures? They also lie about their location while the account details always say Nigeria. It looks like an obvious scam to me, but I keep seeing mutuals commenting on their posts...

A customized inflatable heavy rubber suit from them is a probably my most desired piece of gear.

Perhaps I should save up commission money to get a suit from them...

Wait, MD-Latex is back?! I still don't have the funds to buy any of their suits, but it's great to see that they're producing again.

More Bombot sex at the request of my pal @ultilix.bsky.social (Featuring Cake Bomber from the same universe as the Bombots!) #ocart #nsfw
Two Bombots (bomb-headed humanoid robots) having sex. The one on top is confused, but the bottom one seems to be enjoying itself.Two Bombots having sex with Cake Bomber, an adult female human with green eyes and pink hair tied into long pigtails. She's wearing a black jacket and white undershirt and black pants with black shoes, all with pink trim. Her outfit is in tatters, exposing parts of her body, especially her breasts and groin area which is occupied and partly obscured by the Bombot fucking her pussy. The other Bombot's dick is partway inside Cake's mouth. She tries to push away her assailants with her free hand to no avail.
The whole group is standing in a single spotlight with the text "Game Over" above them.

I'm sort of stuck in a cycle where when I'm working, I can't be bothered to draw, and when I'm studying I can't be bothered drawing, and during weekends I don't want to spend a bunch of hours on it because I'm so slow and it feels like I'm wasting my time...

One of the earlier victims of the infection, a heavier and more aggressive type of drone that tends to incapacitate before infection. In it's eyes, you can't resist the infection if you're not awake and aware to even feel it.~ Personal art! FINALLY!!!

Don't get me wrong, I don't dislike drawing, but it's not something I can do to relax, so when I'm too busy with other things I end up not really drawing much at all.
