Omega, Suppressed by Leann Ryans

Moving from the city to a small town, Shailyn knew things would be different, but she didn’t realize how difficult it would be. When the town leader makes it obvious he does not agree with omegas using heat suppressants, and his son decides to cancel her order for more, she’s left with no choice but to make a trip back to the city to get some before it’s too late.
Alone.
She wouldn’t let their outdated views suppress her right to choose.

This is a slow burn, omegaverse novella. There are detailed scenes and situations that may make some readers uncomfortable.
