Numbing JOI Bet

I don't think orgasms are as much fun of you don't have to work hard for them. If you are just able to jerk off and cum how you want it isn't as good. I want to make this hard for you. I don't think you will be able to cum, but I bet you will try really hard to do it anyway! You will need a numbing spray or lube, one of the ones that is supposed to help reduce feelings to make you last longer. You will cover your cock with it and you will try to jerk off. You will add more when needed and you will work at it until you either give up or you cum! You want to prove me wrong, you want to cum. You will be frustrated and I am sure you will want to let it wear off so you can cum like a regular person, but you will work for this and do as I say!
