I spent time with My three partners yesterday, and two of them wore matching underwear by accident.

So we had to get a couple of adorable pics of Me looking like a happy butt gooner wearing a trailer chic outfit.
A very happy looking man with a goatee, wearing a backwards cap and a Pabst PBR cutoff shirt, is sitting between two very round jockstrapped butts, smiling.

Finished up some rope whipping for a friend before PLPN today. I hope to see some lovely peeps there!
A set of black, twisted bondage rope sits on a table, the ends freshly finished in red sailmaker’s whippings. Little endcaps of paper tape remain on the tips.

“Spring Awakening” was lovely, and everyone did fantastic. Though I really think Wedekind’s text is in desperate need of modernization.

I got lots done after ropes today, and My visitor did so well. Time to relax a bit before I get visited by a cutie patootie.

Goooood morning.

I am back to some function.

I guess I needed to get all My seasonal affective disorder out early, so we skipped Locktober.

I’ll be updating things and back to posting properly soon.

Hey friends! Please support our campaign to raise funds to support advocates going to NJ Exxxotica this weekend. Funds help support lodging and food!

CA: Queerconsulting
This image is a graphic calling for financial support for the SWer Action Alliance, targeting creators involved in an advocacy project at NJ Exxxotica. The composition arranges elements across a light background, featuring a bold title at the top and supporting text at the bottom. A money box and an umbrella icon are placed in the upper portion, while the appeal for funds and donation details take up the lower part. The elements are laid out to direct the viewer’s attention from the title to the donation request. There is no specific framing; the image is presented as a whole. The key visual elements include a money box with a gold coin with a dollar sign on top, a red heart, and a purple umbrella with a pink and blue design, which represents the Sex Worker Action Alliance, with the words "Sex Worker Action Alliance". The text "Support Needed" is stylized in a colorful font. The message emphasizes the need for funds, specifically for food and lodging, directing donors to send money via Cash App. The artistic medium appears to be digital graphic design, using bright, flat colors and bold typography to attract attention. The style is simple and direct, prioritizing clarity and immediate understanding of the message. The creative choices aim to convey urgency and approachability. There is no attempt to create a depth of field or complex visual effects. The setting is undefined, the background is plain and light, creating a clean canvas for the graphic elements. The lighting is even, with no noticeable shadows or light sources, contributing to the flat, illustrative style. The overall mood is one of direct appeal, aiming to convey the urgency and importance of the fundraising effort, with the goal of garnering financial assistance.

Ok folks, it’s PLPN season, and I’m taking out a full page this year! Because it’s been a hell month,

I wasn’t able to find a different image I really vibed with, even though I have some out there, but I thought this one was nice, even though it’s really similar to 2022’s.
A black and white damask pattern with a translucent image of a man in ropes and a gag about to be bitten by a vampire with a goatee. The text overlay reads: Brian Oestmann Professional Dominant Alt-Sex Educator Adult Entertainer “Submission does not mean being weak or passive. It leads to neither fatalism nor capitulation. Just the opposite. True power resides in submission. A power that comes from within.” - Elif Shafak BDSM - Fetish - Fantasy PhillySir.com

Dawn campfire coffee.
An old campfire metal pit surrounded by stones burns with a strong fire. On the camp grill is a pot, and a French press sits open nearby.
