My record is 5 in an hour
I think it definitely takes 2 talented individuals to pull that off lol.
For MSOG, I prefer that a gentlemen let me know that he would like to try for multiples after he arrives and we get comfortable.... I've had incidents in the past when I have tried and it made a gent feel uncomfortable because he knew he wasn't able to do it. Ever since then, I try not to press the issue in case of offending them.
So gents, please speak up if that is something you would like to try
xoxo
