My wife’s boobs were relaxing on the bed just after waking up. Only occasionally now, maybe once every few weeks or once every month does she get the urge to pleasure herself. Typically I have to be gone or not available.
The easiest way is for her to get horny is by working on bookkeeping and pouring through Excel spreadsheets for hours at a time. No joke. Then she gets agitated and fidgety and feels energy build up in her pussy.
Then she needs immediate attention and if I’m not available she can bring herself to climax within a few minutes.
