Diesel, a man of refined oral tastes, is presented with a twitching twink on the couch, his cock hard and ready. Diesel, with a gleam in his eye, leans in, his tongue flicking out to taste the pre-cum beading at the tip. He takes his time, exploring every vein, every ridge, his mouth a warm, wet haven for the twink's throbbing cock. The twink, unable to hold back, jerks off, his hand a blur as he chases his release, fueled by Diesel's expert mouth.
