Electrocution

You pick up the power source wondering how powerful it is. You turn it on and grab the two metal pins by their tops. The top parts are isolated with some rubber preventing the users from zapping themselves.

You want to know how potent this **** device is, so you try the pins against your thigh. You remove them immediately again, as the shock makes you jump. Placing this devilish tool as an option to be used on her makes ninja girl either the toughest or the horniest person you know; maybe a bit of both. Regardless, placing this device in your arsenal takes balls of steel, or more exactly a clit of steel.

You look up at ninja girl and get eye contact. She gives you a confirming nod. To be honest you would most likely have used it on her anyway, the offer is too tempting. You move the two metal pins towards her big pulsating clit, which is wiggling with excitement. You place one on each side of her big love nub and hold it in place with them.

Ninja girl quickly reacts to the electric ****. Her big clit is dancing with the shocks going through it and it looks like it has a mind of its own. Her strong legs are trashing against the restrains in a powerful but ultimately useless attempt to protect her feminine pride. Her back is arching as every muscle in her body is tensing up from the pain.

After about ten seconds you remove the pins, giving ninja girl time to recover. She looks down on you sitting comfortably on the pillow watching and administrating her suffering. You think she is trying to giggle, but the gag ball holds the sound in.

You place the metal pins on her clit once again, and this time you hold them there for a full 20 seconds. From your comfort you are watching her whole body squirm and fight against her restrains. She is in serious pain, and you try to imagine what it must be like to have your womanhood electrocuted while bound helpless like this. Ninja girl is very brave for doing this, and you admire her, while you enjoy every last second of her pain.

A few seconds before you end the ****, you can hear her scream, but the gag ball holds back most of the sound. As you finally remove the pins and put the power source back, ninja girl is breathing heavily. You think that you really pushed her to the limit this time.
