Throw her off of you.

You had to get Rita off of you immediately, before her vibration powers could work their magic on your dick. You attempted to push Rita off of you but she simply laughed and planted herself on your cock, her plump bottom smacking off of you as she slammed down on you. Cursing your bad luck and fighting off a way of pleasure as she ground her hips into you, you summoned up your strength and grabbed Rita by the hips.

"Oh no no no baby," Rita said, grabbing hold of your nipples and stopping your efforts. "You won't get rid of me that easily. Now, sit still and let me fuck you." Rita grinned and you felt an electric surge enter your nipples, causing you to yelp in a strange combination of pleasure and pain. "Do you like that?" She asked, giving you another shot.

"No," you half lied as it had been tantalizing. You grunted through further shocks, now fighting the electric treatment on top of Rita's vibrating pussy. You had to figure something out. And fast.
