I have been doing something for years that makes me cum so hard. Years ago I found at a health food store a small bottle of peppermint oil. The lady who owned the store told me if I take a small amount on the end of a Q-Tip and apply it to my clit and use a vib to massage my pussy, it would feel out of this world. Well I bought it and the first time I used the oil, it felt very warm and I thought about washing it off. But the longer it stayed on, my clit began to feel very sentive. I began to rub my nipples with both hands until they were hard and standing up.
I reached and placed my BOB(Battery Operated Boyfriend)on my pussy. The air running over my clit was helping too. As soon as it touched my clit, I could feel it building up. My hips were moving up and down and I was fucking my BOB so hard. Then it happened! I came so fucking hard that I screamed! I had never done that before. Try it, but be careful not to use a lot, just a little dap will do ya. Have fun masturbating.
