As he rode the rock to the bottom of the water he found Knuckles stuck under a rock so Sonic started to try lifting the rock but since he was so weak and pushing to hard he began to pee his diaper in the water getting it warmer but he didn't care about it as he tried to push the rock up and getting the water warmer and warmer at the same time he looked over
and saw Knuckles waking up and he immediately looked at Sonic peeing in the water while his diaper was full of pee.

Sonic's POV
I held onto the rock for seconds before I found my brother and he was stuck underneath a rock so I tried pulling it but I started Blushing a bit as I felt my pee flooded diaper get warmer which by the way I'm already getting the water warm just by me not taking off this diaper since I overflooded it with pee but I didn't care I kept pushing on the rock and kept my pee flowing into my diaper and the water but the second I look over I began to blush again.

Knuckles's POV
I passed out underwater underneath the rock and I woke up a few seconds later to the water feeling warm and something pulling on the rock and I looked over and found my answers it was Sonic pulling on the rock and wearing a pee flooded diaper around his waist and having more pee flowing due to him pulling on the rock.
