This is how the fantasy goes
Your friend goes to the bathroom and refreshes herself again and gets the washcloths cleaned once more. She comes back to the bed and cleans my face as you go into the bathroom and refresh yourself as well. When you get back you tell her that she is to sit on my face again so you can begin the final session of our encounter. She straddles my face once more, and you begin the final play/torture of your little man.
You start by connecting the two double headed leads on the flexible rubber ring to the TENS unit. You inform your friend that she is about to find out what is the purpose of the two knobs on the flex ring. You connect two of the leads, one green and one yellow, to each of the studs. Next, you take a T-handled metal headed prostate stimulator and coat the head with Vaseline. You connect a black lead (because you know that this lead is a ground lead) to the prostate stimulator and have your friend hold my legs up in the air; at the same time she is still sitting on my face; and you slowly and carefully insert the probe into me anally, wire side up so as to not have the lead come off the unit. You ease the unit inside of me all the way to the base of the T-handle. You instruct your friend to gently let my legs go, and you grab them and ease them down onto the bed. Next, you instruct your friend to securely hold my shaft and keep it from moving as she presses her pussy down on my face. You fill a non-needled syringe with warm cocoa oil and have your friend hold it with her free hand. She remarks as to how exciting the warm oil feels in the syringe and asks what is to become of this oil. Again, you tell her that all is to be revealed very shortly.
