A hairy, uncut giant awakens, accepting the "Shampoo Challenge" in his boxers. His massive, semi-erect cock strains against the fabric, glistening with suds as he strokes it, growing harder and longer. He lathers up, using the shampoo to slick his shaft, groaning as he jerks off, his thick veined cock throbbing in his hand. The amateur stud's balls tighten, and he can't hold back any longer, erupting in a torrent of cum, the milky liquid coating his abs and dripping down his thighs.
