In a forbidden game of taboo, a young man's mind wanders to his stepbrother's massive cock. He imagines the thick, veined shaft, the way it would stretch his mouth wide, the salty taste of pre-cum on his tongue. His hand wraps around his own length, mirroring the fantasy grip. He pictures his stepbrother's face, contorted in pleasure, as he begs him to cum inside him. The pace quickens, the grip tightens, and with a final, desperate thrust, he feels his stepbrother's hot, sticky load filling him up.
