hi selkie,
it is extemely hard to find an online master who you really connect with and who does not turn out to be a toad.. (i used to say frog but think i will change that to toads..)
im not sure what they do but there is a tasking society here... but might be worth checking out...
maybe you know another dom with his own sub but with a little spare time on his hands might pick up the slack from your rl master and allocate you some tasks for a little while..... or can you look at organising the task allocations with your master once a week/fortnight/month.. and you perform them to be reviewed when you met up with your master...and perhaps give your reports a word limit.. so it does not take too long for him to read...
might also be worth considering a domme, top or inexperienced dom you know....
otherwise.. good luck with the searching..xx
