I purchased this when me and my wife first started really focusing on finding all of each others hidden buttons. Boy, oh boy, did I ever nail it. So after our shower and shave routine, I acted as though I had a slight headache, which is not uncommon, and requested that we watch a show to let the headache pills kick in. Well, completely unaware of my oil-soaked fingers, I ever so smoothly applied to her clit as though I had just licked my fingers. After only about 15 seconds of massaging it in I quickly jumped up and with my best pained face said that I needed to use the bathroom. So, about the time I turned the corner, I felt the back of my fingers start to heat up. It was very subtle at first, but it quickly went away. Slightly disappointed I turned around and headed back to where I had left the bottle to see if I had done something wrong maybe or possibly not used enough. I could not have been more wrong. I hear what sounds like my wife crying, so immediately, I fling the door open to find that my wife is, in fact, lying with one hand between her knees and the other gripped tightly around the blanket. I was terrified that I had just found the only liquid sexual enhanced that she was allergic to. I snatch my wife out of the floor, completely oblivious to the abundance of moisture that was now running down my arm and stomach. I could not form the first word, nor would I for the 20 mins following, before my wife had my head snapped back by a fist of hair and my very confused/soft dick now swelling in the back of her throat. I have never came so quickly in my life. For the following 19 minutes, when I tell you that I stopped counting at 9 pulsating whole-body orgasms, I felt like an absolute god. As it turned out, she was, in fact, crying. She was crying because she was blindsided by the overwhelming desire for me to be inside of her, and she thought I was truly sick, so her frustrations only grew as the intensity took over so much so that she could not reach her vibrator just a few feet away from her. I had no clue that any of that was possible and I still cannot tell you what is in there but I can tell you this. She had absolutely no clue what hit her.
