Well, here we are a day later.  So, to re-cap - Master spent two days with me for good behaviour, then two days with L just because they didn't get to talk much the first day.  Then, he came home and we talked and she came over and we had some wine and got in the hot tub and all three of us had sex together in the hot tub and in our bedroom.  He made her lick my pussy, i licked hers  -He made me lick her ass and we sucked His cock and He fucked her with my help.  She stayed over and hung out all the next day - we got along fine and she told Him i was being "really nice" to her.

So, i did well!!  i wasnt' mean or petty and when Master and i had the chance to talk about it through the day when she went to the store - we were able to speak calmly about the few things that were bugging me and he agreed with my points and took my feelings about it into consideration and changed a few little things for my sake.  Overall, it was a very positive experience.  i'm not sure what will happen next - i know she'll still expect to see Him on her own. and i don't really want that - i'm not even sure if it will be harder or easier when He's with her now.

I guess we'll see.  but perspective is everything.  and nothing is certain but change.
