Peeling yourself off the boy's balls, you fall down to the bottom of his shorts. Standing up, you brush yourself off and turn your sights towards your next target, his butt. In front of you, his massive butt cheeks dominate your whole view, his white fleshy globes jiggles occasionally as the tired youth fidgets in his sleep. Taking a deep breath of chlorinated air, you wedge yourself in between Kevin's butt cheeks as you worm your way into the soft mounds.
After a brief trek, your entire body is compressed between the boys cheeks, you find moving to be quite difficult but still manageable. Using both your hands, you start to shimmy your way up the huge crevice towards your goal, his butt hole. Kevin's skin is warm to the touch and a thin layer of sweat has begun to develop from his sun bathing. The further you make your way up, the tighter your confines become. If it wasn't for the light sweat, you would find yourself trapped between Kevin's booty cheeks, the salty liquid sometimes finding it's way into your mouth as you're forced to gulp it down. Eventually, you reach a point where you're unable to move at all, the sweat from earlier was nowhere to be found and you began to consider giving up. As you're mulling your options, you feel Kevin begin to stir as he flips over onto his stomach. You now find yourself able to army crawl towards your objective and using the last of your strength, you push with all your might and feel your left arm break through into an open space. You renew your efforts and slowly slide your way into the cavern. If anyone was able to see you, it would look like the rhino birthing scene from Ace Ventura, as you slither completely inside the tight enclosure.
Taking a minute to catch your breath, your nose is assaulted by the smell of musky sweat, chlorine and rotten eggs. Squinting your eyes, you're barely able to make out anything in front of you. It isn't until you feel Kevin fidgeting more in his sleep that his legs spread enough to let the sun shine down between his bulbous glutes. You watch as the light slowly begins to flood your chamber from above as it washes out the darkness revealing the giant anus in front of you, it's large wrinkles stretching out in front of you like a fleshy spiders web. Kevin's butt hole is mostly pink, the chlorinated water doing a good job of removing most of the left over dung from his past shits, it pulses slightly as the boy breaths in his sleep. While you're busy gawking at the huge hole, you hear a loud gurgling noise coming from behind it, your dick responds accordingly as you realize whats about to happen. You watch as the giant anus bulges outwards as a loud PFFFFFFFFFFT rings out as the boy's anus lazily seeps gas out, the hot fart washes over your small body. Coughing, you have to squint your eyes as the hot gas irritates them, you're barely able to make out his huge ass hole clenching back shut. Regaining your composure, you walk up to the huge orifice, you use all your might to try and force your way inside the gigantic pucker but find it tightly closed. Your world tremors as you feel Kevin wake.
Waking up from his nap in the sun, Kevin stands up and stretches before looking over to his father who is soundly asleep. Seeing his brothers drying off near the edge of a nearby pool , he begins to run over to them. With a loud "CANNON BALL!" he jumps high into the air, tucks his legs to his chest as he splashes down into the cool water. Swimming back up, he breaks the surface of the water to see both his older brothers soaking wet, giggling as they begin to berate him.
"Bro what the hell, we were almost dry!"
"Kevin you little turd! We're about to head home and now we're all wet again!"
"Dad is going to be really mad!"
"I hope you're proud of yourself!"
"Come on that was pretty good huh don't ya think?" Kevin says back with a shit eating grin on his face. He swims back to the edge where both his brothers are as he begins to climb out of the pool.
"I think a little water went up my butt though, it felt really weird!" He continues to talk to his brothers. As he begins to stand up, both his brothers shove him back into the pool before jumping in themselves. As for you, you were...
(1) Flushed inside Kevin's butt hole when he jumped in the pool.
(2) Washed out of Kevin's shorts, you end up somewhere in/on his older, 10 or 11 year old brother, once he jumps in the pool.
(3)Washed out of Kevin's shorts, you end up somewhere in/on his oldest, 12 or 13 year old brother, once he jumps in the pool.
