And adding on, I’m chilling in my recently-arrived sheath boxer briefs from @sysundies.com which are super soft and comfy! Seriously I’ve never felt underwear this soft before.

They also fit pretty well on me, which is a rarity for like most pants/underwear because I’m a very thin guy lol

…. Hi Chiitan? LMAO ???

Otters into sheath undies confirmed??

@sysundies.com making it a comfy workout.

Genuinely delighted with these trunks from @sysundies.com - they're so comfy and a perfect fit. And I couldn't believe how cheap the international shipping on them was.

Made up and can highly recommend 😊

I really think the jock from @sysundies.com really completes the look 😊

A picture of my crotch with me lifting a pair of undies with foxes on them (rudderbutts) to show the fox sheath art on a jock strap (sysundies) worn underneath. Intended to look like a dick pic taken to give a peak under the undies.

Would you like a peek at some fox sheath?

Had a fun idea to ease into irl nsfw stuff and also show off some furry undies from @sysundies.com and @rudderbutts.bsky.social

#irlNSFW #NSFW

After a brief closure, we are once again open - We apologize for the slight pause while the current dumbass US administration irons out its wrinkles.

The de minimis exemption that was reinstated is expected to be temporary, but we are open as normal at this moment!

A bathroom selfie taken of a torso. The photographer is lifting his shirt, revealing the waistband of his underwear. The underwear has a furry sheath printed on it, and the tip of the “lipstick” is slightly visible.

Honestly kinda digging this look~
