Biceps flexing, the muscular teen, a self-proclaimed muscle slut, stands before the mirror, admiring his reflection. His massive cock, a testament to his dedication to the gym, juts out proudly. He spits into his palm, lubricating his hand before wrapping it around his shaft. His strokes are long and slow, milking his cock from base to tip. His other hand pinches and pulls at his nipples, sending jolts of electricity straight to his throbbing member.
