Wanking therapy for a jerk addict

Your wife has been sending you to me for the past few months to get your despicable wanking habits under control. To my horror she called me this morning and told me my 'techniques' simply aren't working, and I must inform you that your wife pays me good cash to see you. I simply cannot lose this income, your wife fuels my lifestyle... so let's make a compromise shall we. If I give you a hot, JOI session once a week you must completely refrain from touching your cock, apart from with me during my therapy sessions.
