31 [M4F] Dissolving shorts prank

You are my girlfriend and we are on a vacation to the beach. You got me a present, a new pair of swim trunks. They’re awesome. But unbeknownst to me they are dissolving swim trunks that you bought off of the internet. Essentially they look and feel like normal shorts until you get in the water. Then they disappear, leaving the unsuspecting victim naked and embarrassed in the water. To add insult to injury, you know what happens to guys in cold water. The shrinkage just makes the whole experience even more embarrassing than it already is. And as my girlfriend, you know how self conscious I am about my size. And you know why. I’m woefully under endowed.

Will we be at the pool with a swim up bar full of people lounging around drinking? Or will we be down on the crowded beach, full of sunbathers? Will you be kind and bring me a towel? Or will you make me go on a naked run with nothing but my hands to preserve my modesty. I guess on the bright side, at least my equipment is easy to cover up.

My kinks are small penis humiliation, clothed female nude male, embarrassment.

I think this can be a really fun one for both people. Looking forward to hearing from you.
