Testing Nerine Mechanique

Nerine sits in the chair like she knows what she is. The questions cut straight to it: how far can she go when the pain starts to bite? She answers with her body before she speaks. The ropes come next. Her wrists cinch behind the bench, ankles spread, face pressed low. She wants the title of trainee bad enough to take whatever is handed out, so I hand it out. Every slap lands sharp. Every clamp bites deeper. Her eyes water but she stays open, offering her ass like it belongs to the scene. I work her rim slow, stretch her until the muscle gives, and push past it. She takes the stretch and begs for more without saying a word. Later she kneels, lips stretched wide around me, throat working to keep steady while her arms stay locked behind her. She gags once, twice, keeps going. When the last rope loosens she stays on her knees, breathing hard, ready for the next test.
