Bust Sara! (Success yet fail)

Your eyes start adjusting to the dark and you notice your friend hiding in the corner with a remote. Filled with rage, you run at her. You must have caught her off gaurd, she didn't command her robot to stop you. 'Now she never will' you think as you snatch the remote from her hands. You throw it to the ground then begin stomping on it until you're satisfied it's broken beyond repair.

"What did you just do?" Sara demands. She sounds panicked, but you don't care. You can take her on and you know she deserves it. She should be scared.

"I evened the playing field."

"No, you just broke the only thing keeping the robot under control! It's going to target both of us now and it's safety features probably shut off!" You hear a whir from the machine behind you, but looking back you see it hasn't moved so you ignore it.

"What safety features? It was just brutalizing my cunt!"

"Yeah, but it wouldn't go above bruising level! I didn't want to give you any permanent damage from it! I mean, safety might still be on, but I don't know for sure. We need to get out of here before we find out!" She rushes past you, bumping into you and knocking you over as she runs towards the door. She doesn't make it that far. Instead, the robot whirs to life and launches a metal rod into her pussy.

BAM! It was a hard enough blow to lift her a few inches in the air. You could imagine her pussy lips squishing to the side as her clit compresses from the blow and hold your own cunt in sympathy. She shrieks from the hit and crumples to the ground, writhing around in pain as she craddles her cunt. It must have hit her clit dead on. But what activated it? It wasn't moving when you were talking!
