He has the same feeling he did when he first kissed his brother, when they first held hands. When they first embraced their feelings.

It's warm, and intoxicating, yet it brings him down and makes him aware of every single sense he never knew he had. He just closes his eyes and let's it flow through him, it the greatest escasty he's ever felt.

The water isn't hindering them as it should. Instead it seems to just wrap them together, binding them in it's hold. For the first time in his life he feels like everything is finally going as it should.

The air from his lung is dissipating, and he feels his older brother's mouth convulse against his. 
He knows they're moments away-seconds even...from oblivion.

And instead of fear or panic he merely pulls closer, embracing anything so long as he's in the arms of his love.
