It realisticly depends on the bull, if you meet up with an experienced man that makes you both feel comfortable and relaxed! Even better if hes a well mannered gentleman because that will make your wife feel special and wanted. This is all good but be careful what you wish for... because if this happens and your wife has a fornix orgasm with him, she will be going back for more every few days, and you will be digesting how addicted your wife has become.
