Wraff Puppy got some new underwear from @sysundies.com #nationalunderwearday #underwear #bulge #twink #puppy #pup #humanpup #nsfw #kink

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??

2/2 I am really liking how comfortable the boxers are, @sysundies.com is good.

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 😊 Come wrestle an excited puppy 😋

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! sysundies.com

Real talk, We've wanted to expand back into these undies for like.. almost a decade, and were nervous as hell to do so, but the positive reception and photos everyone is sharing is absolutely the biggest sigh of relief and happy brain vibrations all round. Thank you animals.

Got my @sysundies.com order in earlier~ Gotta hand it to 'em, these are some of the most comfortable I've ever worn. 💜

Anyone remember when Flickr was all the rage? I think it's time to bring back #FunderwearFriday! Today's #funderwear is the furry wolf jock from @sysundies.com

Can't help it, looking at these undies from @sysundies.com is borderline addicting. They feel great, look great.

Hey puppy. I can't tell you how much I love having your nose buried in my bulge. I'm gonna grab your head, pull it right in, and hold you still until I feel a loooong, deeeeep sniff for your big, Daddy Shep. Rrrrgghff! 💛

Loki's new undies told him to Show Your Sheath, so he did exactly that :3 @sysundies.com

So many of you talked to me today, unbeknownst of the sheef beneef… 😈 Thanks @sysundies.com ! Super comfortable and stylish :3 💕

Blown away at how perfect this looks OMG

Sheath undies arrived @pocketfox.bsky.social @doggoderg.bsky.social @cerrifox.bsky.social @sysundies.com

Canadian Shipment Update; Itt appears that private couriers (UPS+Purolator) are no longer accepting any Canadian bound shipments due to their services being overwhelmed. This means we cannot offer any shipments to Canada until the strike is over. We are so sorry for the frustration.

Peekaboo 😘 Loving my new jocks from @sysundies.com

Got some new wolfy sheath buffalo-plaid trunks and a fox jock from @sysundies.com in the mail the other day and finally got to try them on this evening... Fun times, even for the merely furr-adjacent like me! (Sorry the colors are a bit weird. The light in my dungeon is all red... 😏😜😁👍)

holy shit I cant believe how good these things look in PET SUITS, we never tried that out. HOLY SHIT they look so good 😫

Since you all seemed to like the previous one so much, why not have another~ Once again HUGE thank you to @sysundies.com for the boxers, and special shout-out to @were.dog for the XL canine sheath to make it that much more perfect~

Hey y'all! We sold about 30% of our inventory in the first day which is freaking wackadoodle. Some styles are close to selling out. Our next restock will be in about ~2-3 months from now, so just wanted to give you a heads up if you were thinking about grabbing some sheaths! sysundies.com

My order from @sysundies.com arrived! I was a bit nervous getting my first jockstrap (of course got the matching boxers) but oh my LORD they are comfy Bonus points for defining my butt too >w> GO CHECK EM OUT AND GET SOME YOURSELVES

SYS Underwear is OPEN! Sorry for the slight delay, animals. Everything is stocked up and ready to ship! Thank you to everyone who supported us getting these off the ground, we can't wait to expand the line and only make more amazing things happen from here! sysundies.com
