The nagging feeling of a full bladder woke me up. Groggy, I opened my eyes and looked around the dark den.
The wolves were sleeping. Reluctant and as careful as I could, I tried to manouver myself out from in between their warm bodies. Of course, there was no way I would manage that without waking at least one of them up.
"Hey, what are you doing?", Luri softly asked me while yawning.
"I uh. I need to go to the bathroom", I answered without thinking.
"The what?"
"Ah yes. Right. I need to pee. My bladder is so full that it's painful."
"You can't even sleep a night without having to pee?", Sura, who was also woken up asked.
Akru grinned to Sura and shook his head, "Must be a human thing."
Pretending I didn't hear that, I pushed myself up on my hands and knees. "Is there any particular place where I can relieve myself? Like, some special rock or a tree?"
Alexander nudged me, "Come, I'll show you. Wolves use their urine for marking off their territory, so doing it in the wrong spot might offend other pack members."

I streched out my muscles in the cool, early morning air. The breeze on my bare skin made me shiver. The forest was still dark, and bathed in eerie pale moon light.
Alexander took me around to the back of the den's mound. "Here, go right ahead."
I walked a few paces behind one of the trees, and relieved myself.
The big wolf grinned as he watched me. "You're marking a lot higher than any wolf ever could reach. It might be better to just do it on the ground the next time."
A bit startled by that, I finished and followed Alexander back to the den's entrance, crawled back in on my hands and knees and lay down on the soft den floor. Before long, I was all snug between the wolves again, warmed back up by their soft and thick fur.
"All better now?", Alexander kindly asked while giving my face a warm lick.
"Much, yes", I sleepily replied, giving in to the wolf's friendly tonguebathing before resting my head against his chest.
Luri nuzzled my belly, "Let's get you cleaned up so you can get back to sleep."
I opened my eyes, "Cleaned up? What do you mean?"
"Oh, you can not reach down there. And it's very important to keep yourself clean. Else all kinds of things can accumulate under your skin and cause problems."
"I uh. Can do that myself tomorrow while taking a swim in the lake?", I rather nervously replied after realizing what the she-wolf meant.
"Oh, don't be such a fuss", Akru replied. "We always helped out Mowgli after he went for a nature call. He probably still needed to be licked, because quite often it made him go again."
"That is how we help out cubs", Luri explained. "It helps them to go when they are being licked. But you probably just need a cleaning there."
"Go on, roll over, silly", Sura kindly insisted while nudging my flank with his cold nose.
I shrugged and let the wolves have their way.
"There we go", Luri fussed, "Just let Sura take care of you."
Sura started to lick my balls and shaft a few times before he pressed down on my tip, pushing my foreskin down with his lips almost effortlessly. Slowly and thoroughly, the young adult wolf curled his soft and warm tongue around my glans as if he was cleaning himself. 
My arousal quickly built up, and I kind of hoped Sura decided to be done with me before I would be pushed beyond the point of no return. However, Sura persisted and made sure not to miss an inch of my male anatomy. Over and over. 
I clenched my jaw and inhaled loudly, gasping, my groin tingling. 
Alexander noticed and rubbed his muzzle over my cheeks and mouth. "Don't worry or be ashamed when you need to go again", he smiled. "Just let it happen."
My body tensed up, and with a grunt, I ejaculated in Sura's maw. 
"There you go", Alexander smiled, "All done."
Sura continued licking until I was soft, after which he pushed himself back up against me.
All snug and warm and cuddled in between Alexander, Luri, Sura and Akru, I wondered if they knew what that "made him go again" actually was. I decided to hold that thought for later, and buried my face in the soft fur.
