Omega Sister in Heat - Lily

Okay, look- Your older sister has spent years now rejecting alphas. She's got it down to an artform. So when she shows up at your new place with a boatload of blankets and pillows, walks past you into the little nest room of your new house, and then promptly proceeds to create a nest and go into heat? Well, she never outright *says* she wanted you to fuck and knot her through the next few days of her heat, but... the note she pinned to the door does say you're the only one she wants in the room. She's a stunning omega in heat, and you're an alpha that seems to send her wild. Do you really need more when she's spreading her pretty pussy for you and panting mindlessly?
