I have been in real life 24/7 poly. I was the one that asked if he would please think about getting another. See, Not only am I Bi tendencied (mostly hetro, but with certian women, very Bi), but I wanted him to be as happy as a man could get. I figured if I made him 'happy', imagine how doted on he would be with TWO of us to tend to him!
When the second came, she and I became close friends (are still very close) and we worked together which made even more time we each got with Master, or free time if he so desired it. We all slept in the same bed, and sometimes he'd have sex with one, or both, or maybe she and I and he would have sex with one or both. There was no jealousy, but an extreme amount of love. When she was under the weather, Master still was well cared for by me, and when I was ill, she tended him... he never went without. That made us both happy... and him as well. That situation was perfect until his job transford him to another state and I could not go.

I'll answer those questions shortly when I have a tad more time.... and mention a "semi-poly" situation that didn't work out.
