Ok since you are new let's go easy a light spanking and the beginning of orgasm control.
Go ahead and spank each of your butt cheeks 10 times, and if you can do this in front of a mirror and watch yourself as you do this task. Also try to be consistent with the force you use to spank yourself so that we have a baseline to work with.
Now for the orgasm control. Go ahead and masturbate but stop sort of cumming/orgasm. Take a breather until you are ok and will not cum. Now go on with your day. This last task I want you to do once a day, every day for the next 7 days. If at anytime you fail and do cum/orgasm then either reply or pm me so that I can deal with you. If on the other hand you succeed then on the 8th day either reply or pm and we can talk about a reward.
