Be careful if you have daughters or a sister. Me and my wife are still married and have great sex on top of her getting it on the side. She has been doing this for along time.
But like my wife you will go through stages, first getting with one, it starts very intense and animalistic, so says my wife.
Then you will gat tired of the one on one and move on to getting it from two or more. After getting tired of that you will want to trick or temp others to it. You become like the cock hold or cut hold getting off on others getting off.
So either at the beginning or close to the end of it, you will try get your daughter or sister into it by tricking or seducing them. For one of two reasons this will happen, you want them to feel it like you did, have very intense sex or you will get off on watching and hearing them get it for the first time.
Be sure you under stand what you are getting into. My wife has said you can lose you mind to it.
