I mean, if you really want it...

What challenge?

Because someone out there likes videos of women smashing small animals to death with their feet. I do believe there might be people out there who like boobs (this picture hits that note), people who like boobs being 'presented' to them (this picture really hits that), and there might be people who like boobs that are ready to be smashed between two boards as if they're a nsfw revival of the hydraulic press channel.

I dunno. I just saw boobs and clicked the upvote and didn't think about the board.

O.o Do you want research papers and essays? I'm tangentially aware of the skin microbiome (yay, how everything in microbiology is supposed to be related so we all are expected to know what the weird fucking colleagues are doing in those nasty skin crevices instead of clean[ish] brackish water systems that are where the real science happens) and the amount of information on the workings of all the little microbes on your beautiful holobiont is astonishing. Like, the difference between what people think they know about our mutualistic relationships with our symbionts and what is really known is massive. Imagine the difference between the grade school kid who knows we eat food for energy, and the undergrad learning about the Kreb cycle. It's bigger than that! It's more like the difference between the neonate on the breast and the senior undergrad studying the enzymes that facilitate the rearrangements of molecules in the Kreb cycle. The sheer amount of control that microbes in your gut and on your skin (and other places too) have on your body boggles the mind. Did you know the microbes in your gut can control your mind?

If you want some fun, do a quick search on your favorite database for the terms "allergen," "cockroach," and "dog." Then go for "SCFA," "immune system," and "Firmicutes." You can also use "Bacillota" instead of Firmicutes, because people want to be trendy. Go for a deep dive with "breast," "microbiome," "milk," "gut," and "bottle."

Eh, the worst that could ever happen is we would set up something along the lines of one of the dildos on the wall/floor in front of me, and him behind. He'd pound away, pushing me ever further onto the silicone. Plus, can you imagine how much fun it would be to make him sit in a chair and watch me go to town, having to wait his turn? Teasing is an understatement! No practice ever wasted ;)

Only if you ask me to.

The one I really want to find was the first every porn I saw, presented by my friend who had just been given a CD full of short vids.

It was three women, with one laying prone facing away from the camera, which was focused on her ass and vagina. The other two were playing with her, one was slowly pushing some sort of hollow-looking dildo into her ass and pulling it out again. During the video, you can slowly see the middle woman's vaginal lips swell with blood and part as she became more aroused.

It looks more like two kidneys to me.

Haha, no! I've always followed the pre-social-media-selling-our-info advice of no real names, and definitely no pictures. In person meetings or bust!

...

...

and bust? Hmm, decisions.

If you can stomach going back to reddit, or using one of the front-ends that still work, the old bad dragon subreddit had a list of dozens or hundreds of manufacturers. Pick one that looks enticing, is a size you can like, and that has good reviews so you know you're not buying poor quality.

Progress on the oral? Some. I feel more confident with it. On the deepthroating? None. :(

I don't think I've quite got that sort of capacity. It would be a pretty good experience to try something interesting though. Kirby breathes fire if he eats fire... I wonder if I could convince someone to drizzle jalapeno juice on themselves. The burn in the mouth and throat from being face-fucked, with the usual fun? Are penises sensitive to capsaicin?
