Biceps burning pleasure

When my biceps burns, it's the best pain in the world. i enjoy it and it's time to light them up. i am dressed in my training clothes: leggings, sports top, and sneakers and i pose in front of the mirror. i like to watch my muscles twitch and tense. i like to see the contractions of my biceps as i flex my arms and sigh with pleasure. then i take dumbbells and start pumping my muscles. i feel my arms grow with each repetition and the power flows through them. pleasant pain makes me moan. but i still want it to hurt a little more, and that’s why i don’t stop. i contract my muscles as the temperature rises and i feel sweat slowly breaking through my skin. my biceps bulge and my triceps is protruding as i stretch my arm through the pain in a controlled manner. i end up posing for you. slowly, and seductively.
