A while ago - before I went to visit Master - I had a very interesting experience with Lupa and a guy I'll call Finnian. He's a friend of ours, two years younger than Lupa and me, and he has a bit of a romantic history with Lupa, though the two have never been together officially.
Anyway, since the beginning of this year I've caught myself eying Finnian like a cat eying a plump squirrel. He's a good friend, he's funny, and he's attractive to boot - and I've been rather hungry now that Master's gone. But I know that Lupa still likes him (kind of; she's got mixed feelings) and he still likes her (probably), so I haven't done much more than watch him and chatter my teeth with anticipation.
However, there is one thing that Finnian and I both love to do, and that's torment Lupa. One night, Lupa was miserable from studying for a particularly vicious test, so Finnian and I took it upon ourselves to distract her. Our teasing and biting and licking escalated pretty quickly, but because we were in the living room we couldn't progress beyond a certain point without fear of it getting very awkward should a roommate happen to come in. But it was pretty obvious we all wanted to go further.
Master has been telling me I need to be more assertive. And Lupa and I had been joking for weeks about doing a "Twin Cougar Strike" on Finnian (a play on the name of an attack power in Dungeons & Dragons (yeah, we're super nerds)). This, I realized, was the perfect opportunity.
"Do you wanna go upstairs?" I whispered in Lupa's ear. After much incomprehensible flailing, Lupa nodded, so I helped her to her feet (her legs were already a little wobbly at this point). Then I turned to Finnian. "[Lupa] and I are going upstairs to have randy lesbian sex," I said, sounding much calmer than I felt. "You're welcome to come, if you'd like."
"Sure," Finnian said after a pause. "Might learn a thing or two."
So yeah. It was funny, because while I definitely participated, it felt a lot like I was orchestrating Lupa and Finnian's actions. Which was just fine - I like being a voyeur - but it was strange. It was much more intellectual, more "heady" than I usually am during sex. Sometimes I'd even be so explicit as to tell Finnian, "Do this," so he'd know precisely what Lupa liked, and a couple times I even manhandled the two into a better position for sexin'.
I don't think I'd call what I did "dominating," though, because I wasn't imposing my will on either of them. I was guiding them, giving them suggestions, that kind of thing. Mostly because both of them are pretty inexperienced compared to me. (And lordy do I feel weird saying that. Me? Experienced?!) Finnian was actually the least experienced of us, which was both fun and frustrating. It was fun because we got to experiment with what he liked, but it was frustrating because even he didn't know what he liked, so he couldn't just tell us. And his technique could use a little improvement, but that can only come with more practice! :)
Since then, I've wanted to be intimate with Finnian again - without Lupa. I'm not sure why I have that particular desire; I think it's a possession/dominance thing. "He's mine, see, I can do what I want with him." Which is petty, to be sure, and besides there's still the fact that there's more chemistry between those two than between him and me. Soooo it's probably not going to happen, but try telling my Id that.
