Me and G

It's been two weeks since I saw G and we had our rendezvous.
He calls me a lot and sends email, looking forward to the next time we meet.
He knows my other lover is dominant and I am submissive,
but since he's known me for several years (as a friend), this dynamic is something he's trying to figure out.
'So did you two have fun last night?" he asks."I went to the movies" (with his partner).
"Yeah, we went to a film,"I say.
"And then did Z tie you up?" he asks.
I laugh. "You don't want to go there unless you really want me to tell you, right?"I say.
"Yeah, okay, you're right...but I just hope you're having fun."
"Oh, I'm having a wonderful time," I respond, knowing there is no way to explain to him what Z and I do that captures how it feels.
"Just so you don't get hurt..."he begins, and I laugh and cut him off.
"--You mean in ways that I don't want to be?"
And then I stop, because explaining it all to him is just too complicated for a phone call--and it's really none of his business, anyway.
