Working Overtime in Underwear by Tarutoro

 It's after work at the Men's Underwear company. 

Two designers have invited their Manager to check out their latest ideas.

They ask him to try some of them on, surprising and embarrassing him, somewhat.

Inside leg measurement is not usually needed for fitting underwear, but one of the designers has his tape measure out and is angling his knuckles in the direction of the bemused manager's crotch.
The designers both have rather intense expressions.

Surprisingly, the Manager takes off his trousers in front of his employees. This reveals that he has formidable thighs. He should make a good model for their new pants. His own underwear is conventional - loose fitting jockey shorts. That's because he's got a thing about tight underpants making him sweat. Talking of which, the kneeling designer's face is already looking a bit flustered. 

 

When the Manager takes off his shirt, he proves to have a highly muscular physique.

His hobby is lifting weights at the gym, which perhaps explains his lack of modesty.

 

The new designs are a lot briefer and tighter than his usual underwear, 

but he remarks that the soft material feels good on him.

They look good too, he is assured (in croaky voices, I imagine)

 

 

The underpants get briefer still - and more daring. The Manager is embarrassed that this mesh design shows his bits (although by this time he's been in and out of underwear several times in front of his employees). The designers don't disguise their admiration for him, they hastily explain that the mesh prevents sweaty dick syndrome. It looks as if the designer on the right already has that problem.

 

They persuade him to try on one last pair - a jockstrap design, well, sort of.

 

"These are ridiculous", he exclaims, "I can hardly get into them".

"Your cock is too big", they explain, rather unnecessarily, 

"the hole is only meant to show your pubic hair". 

This explanation does nothing to cool the atmosphere and inevitably, the Manager's dick slips out into the open, already on the way to erection. Perhaps he's finally realised that he's on the brink of a CMNM situation.  The trousers of his opposite number go into full tent mode in response, mirroring his arousal (image omitted, sorry!).

 

 

As well as having half a sling pouch at the front, the jock design, of course, completely exposes and frames the Manager's ass. He doesn't seem to have noticed, but the others have, and now they pounce. 

"Just our little joke!" they exclaim, playfully unzipping and spreading their legs.

The Manager protests at this lack of professionalism in the Office, (fleetingly).

 

Thereafter, male nature takes its course in a number of iterations of this image, 

including one with the memorable remark - "Don't stick it up my ass! Ouch! No!"

Ouch, indeed!

 I'll let you track down that image and others I've omitted, yourselves (link below). There's also a set with speech bubbles setting out the action and embarrassment factor, but the language and emotions don't translate into English very well.
