Sigma : The Fourth Gender
Dean's never belonged anywhere. Not at home, or at school, hell even on the road by himself he felt odd, not even comfortable in his own skin. Since he presented as beta at twelve years old, it's been a long line of failed relationships, bad run ins with alphas, and betas, and one night stands with omegas. Everything changes when he decides to buy the blue-eyed omega at the bar a drink. Before he knows it, he's been dominated by an omega, is kissing Superman, eating pancakes in his boxers, and is about to join the Household of Castiel Novak. Hell, he might not even be beta after all. Figures he'd be some new-aged fourth gender, or some shit. This is either going to be the best, or worst situation he's ever gotten himself into.
