Now that your balls are prepped for training, we need to work on your asshole.
In the shower, after you rinse the shaving cream and hair off, get your hand really soapy and start cleaning your ass. Do not touch your penis unless I tell you to. Spread your ass and really rub that asshole, get the blood flowing to it. Keep rubbing your ass until I tell you to stop.
Start gently and slowly get rougher, adding soap. If you finger slips inside, that's fine, but you are required only to rub it as vigorously as you can. Do this for at least one minute, then you may stop.
Rinse your ass thoroughly and continue.
