The brother's huge cock strains against his jeans, the outline clear and enticing. He unzips, releasing his engorged member, and begins to stroke slowly, building momentum. His hand, slick with spit, slides up and down his veiny shaft, the head purple and leaking. He grunts, his body tensing as he nears climax, his ass cheeks clenching, before he finally unleashes a torrent of cum, his body shuddering with each spurt.
