A new lotion powered by nanites is released by an adult toy industry and samples are sent out to random customers who signed a waiver agreeing to test the product. The lotion is sent to male and female customers alike.

The instructions are simple:

For Women:

Thoroughly apply the lotion to your vagina both inside and out. After about 30 seconds you should notice a significant increase in your libido as your vagina begins to masturbate itself. You can also apply the lotion to your breasts as well.

For Men:

Thoroughly apply the lotion to your penis (testicles optional) starting with the base of the shaft all the way to the head. After about 30 seconds you should notice a significant increase in your libido as your penis begins to erect and masturbate itself.

Warning

This product is not fully tested. The effects of this product could last between 30min and 24 hours. Use at your own risk.

(Rules: I’m leaving this one pretty open so be creative! You can focus on just a male or female character, or involve a group of people. Maybe the character is good and only uses the product on themselves, or maybe they play pranks and give the lotion to unsuspecting people. Maybe the AI in the nanites is too intelligent, causing the body part to gain sentience or never lose its effectiveness. These are just some ideas, but don’t be limited by them. Of course, abide by site rules and all characters involved in sexual acts must be 18 or older.)

Have Fun!
