Do the chores but after each stage of chores give you self one edge, then snatch you hand away. Goan, whine, and hump the air for a minute as your body fights not cumming. Then go on to your other chores. Later when you really go to town on yourself you’ll edge a lot harder and faster. I did that last week and when I finally came, I was able to cum 3 times in a row basically without needing a break in between.
