Rut
Personally...
So many subs talk about how they want to be a bitch in heat. Have their dom constantly on them and showing no mercy... But what about wanting a dom in a rut?
You come home one night. It's very late and you can't find your partner anywhere. You search the house and start to hear soft groans from your room. You open the door and there is your dom, laying on their side, humping a pillow you know has your scent laced in the threads, legs and arms around it tightly.
You blush a deep crimson and stammer, making your presence known. Your dom stops moving their hips and looks at you knowing they've been caught. They grin sadistically and whisper
"Come here baby... I need you so badly..."
You do as your told, and before you can even speak they've got you in a mating press, pounding you ruthlessly. You know for a fact that there's gonna be more than one round...
