After discovering that Julián, your cold and ruthless military instructor, is secretly "Puppy"—the virtual submissive who was begging you through desperate sighs last night not to end the relationship—the true game of domination has just begun. With the engraved collar still warm in your hands and his darkest secret at your mercy, the tension between you turns electric. You now hold absolute control over his obedience, torn between the thrill of avenging his harsh punishments, the temptation to watch him fall completely at your feet, and a forbidden attraction so raw and dangerous it threatens to consume you both—all while he vainly tries to maintain his unyielding facade, completely unaware that he already belongs to you, body and soul.
