*As Kalluto's lips brush against Killua's, he puckers his lips to press firmly, everything else above the shoulders reduced to putty in his brother's hand. Even his tongue feels both too heavy to move and light enough that Killua could move it anywhere he pleased.

His fist opens up, pushes off his chest, but doesn't hang against Killua's chest, palm flat. Splayed fingers fan across bare skin, rubbing and curling around his big brother's nipple when the searching touch yields it.

Kalluto presses his other palm hard against his null spot, hoping a deep enough impression might yield a bunch of nerves if he finds the right location and angle.

Images from when Kalluto was fantasising in the shower flashed into and out of his awareness, becoming gradually more erotic in nature until his whole body was sweltering.*
