He gives in, and they set off for the lakehouse.

I was flabbergasted. I could not believe what was happening. But I realized that there really was no way out of this. Mom was already gone, there weren't any houses for miles, and even if I refused, Uncle John could easily strip me himself. With a sigh, and an ever reddening face, I slowly began to strip, taking off my shirt, shoes, socks, and more reluctantly my pants.

As my basketball shorts hit the floor, my uncle burst out laughing once more at the sight of my underwear, as my face reddened even more.

Looking down at the old and slightly too small grey briefs I had randomly thrown on while getting ready, I realized that while definitely embarrassed by all this, for some reason my body responded in the opposite way. My cock, which was already barely contained by the tight briefs, had also begun to grow into a raging hard on from the thought of being exposed.

"God damn Mark! I thought you didn't wanna get naked!" Uncle John laughed. "Seems you're more excited than I thought! Damn that's quite the python you got right there, let's see it in the flesh!"

I was mortified. My cock quickly grew to a full erection at that comment, twitching and straining to be set free from my briefs. I couldn't move. My uncle was staring and laughing directly at my throbbing erection. I could barely process any of it. I just stood their, face beet red.
Suddenly, Uncle John hopped off of his boat; his flaccid genitals flopping up and down with the motion. "Seems you need a little help." He spoke with a chuckle, before yanking my briefs down to my ankles, freeing my cock from its confines. Upon its release, it sprung up at full attention, thwacking the pubic region above my genitals with a SMACK!

Before I could even react, Uncle John quickly swooped up the rest of my clothes, tossed them in the safe, and slamed it shut; a clicking sound indicating that our clothes were locked in.

I could not believe it. I now had nothing. All of my possessions, clothes, any means of cover had been stripped and locked away, leaving me completely naked. Realizing this, I quickly tried covering my raging hard on with my hands; an action that had little to no effect, as I was unable to fully hide my hard cock beneath my hands.

"Oh come on John, don't look so glum. It's completely natural." Uncle John reassured me, putting an arm around my shoulder. "It just means your body is enjoying this. Just let your body do its thing and enjoy yourself. You'll see it's more nice of a feeling than you think." He smiled.

While still embarrassed beyond belief, his words did resonate in my mind a little. As much as I hated this idea, it was turning me on, and I couldn't deny that it wasn't entirely a bad feeling.

"Oh, and a word of advice." Uncle John said playfully with a smirk. "Stop trying to hide that python of yours behind your hands. It doesn't work. And from experience, lemme tell ya that holding your hands on that thing will only make it harder!" He laughed as I blushed more. He then smacked my ass hard, before running towards the boat. "Now come on, stop that dilly dallying and let's get a move on!"

Stumbling foward from the sharp whack on my ass, my arms had spread out to balance myself, once again exposing my hard on. Blushing profusely, I almost covered up again, but decided that there was no use in trying, and hopped on the boat with my uncle, hard cock bouncing with each step.

"Trust me when I tell you this is a week you won't forget!" Uncle John smiled as he started the boat, accelerating out into the open waters.

Looking at the situation, with both my uncle and I butt naked without any access to clothes for a whole week... yeah. I don't think this is a week I'll ever forget.
