Lip Trip ~Boss wa Watashi no Genetsuzai~

In the Omegaverse, everyone is born into one of three secondary genders: Alpha (α), Beta (β), or Omega (Ω).

Rino is an Omega, and a new recruit working for a digital travel magazine. Chizu is an Alpha, and Rino's boss. "Um, Boss! It's my first day, and..." The moment Rino hears her boss's voice, she suddenly goes into an off-cycle heat! Chizu respects the fact that Rino doesn't want to quit her job just because of her natural urges as an Omega and makes a decision to help her. "Just bear with it. I'll get it over with soon." Entranced by her cool fingers and sweet scent, Rino gives her body over to Chizu. Fate begins to toy with the two as their feelings dance the fine line between reason and instinct...
