if my Mistress is too busy to play or spend time with me, she knows i have needs and she wants me satisfied just as i want her to be satisfied at all times. she will give me permission to play on my own and come if we cannot play together due to other obligations. then i usually have to write her an email after i play telling her about what i did and what i thought about.
i think one has to know that you have needs and just because he is busy doesn't mean you should be put on hold.
