Thats enough of that.
You have been so good in following my instructions, I think Ill let you cum soon.
But I want you on the edge of orgasm until then.
When I say you can cum, you have to do it how I say.
Right when you go over the edge, let go of your cock and squeeze your balls as hard as you can. If you dont cum like this, I assure your wife will be none too pleased. Youll be out on the street in a matter of minutes.
Get to the edge then hit continue.
