I suppose I should get around to talking about my playtime with Master and Lupa.
It actually happened rather suddenly. I was over at Master's apartment and he suddenly asked, "Do you want to ask [Lupa] if she wants to stay over?"
I blinked as I processed what he was saying. "Okay!" I called her on my phone; once she picked up, I said, "Saay... I'm staying over at [Master's] tonight, and we were wondering if you'd like to come over... and perhaps stay over."
"Oh reeaaaallly?" Lupa replied.
"No pressure; you don't have to."
"Do you guys have an alarm? I have to get up early tomorrow."
"Yeah, we can set an alarm for you."
"Okay! I'll be right over."
As Master and I waited for Lupa to arrive, he asked me what I wanted to do this time around. I said I liked the game "Who's On Top" last time we played, so it'd be cool to do that again. The element of chance was thrilling. When Lupa came over, we played video games and talked and hung out until bedtime. At that point, Master took us into the bedroom and said, "Now [Lupa], do you remember the game we played last time? 'Who's On Top?' Tonight were going to play a slightly different game called... [Lupa's] On Bottom."
Lupa and I giggled excitedly. After much caressing and kissing and so on, we tied Lupa's hands behind her back and pushed her down onto the bed. Then we started playing with her ass - spanking, fondling, and eventually cropping and flogging, too. Master and I switched off; one would beat her ass while the other would kiss and caress her top half. Lupa tends to wear several layers, and that night was no exception; we would peel away one layer, spank/flog/etc her ass some more, than slowly remove the next layer, and continue the process untill we'd reached bare skin. Her cheeks were a beautiful cherry red - it was fascinating! I couldn't stop touching and caressing and fondling her ass.
It was a bit strange because throughout it all I didn't feel particularly dominant. I felt... playful. Like when I play-wrestle or have a poke-war with a friend of mine; I'm being forceful, yes, and physical, but only because I like to tease my friend and get a reaction from them, not because I want to assert power or control. So, yes, I was topping, but I wasn't domming. I still felt distinctly submissive to Master the entire time; I looked to him for direction.
Anyway, eventually we all got naked and moved on to the sexin'. I got to use my strap-on for the first time. ^_^ It was pretty awkward at first, since I'd never used one before, but the entire scene was very low-key and low-pressure, so we just fumbled along and giggled at any mistakes. As long as we enjoyed ourselves, yeah?
Using the strap-on was... interesting. I mean, it definitely felt great. The pressure on my pubic bone was amazing, and at one point Master started going down on Lupa while I was inside her, and I could feel the vibrations up my toy - incredible! I could even feel her pulse. But, on the other hand, I had no kinesthetic awareness with the toy. I couldn't feel if I was inside Lupa or not; I couldn't feel if I was too deep or not deep enough or anything (easily remidied by Lupa telling me, but still). I also wasn't at all used to the whole thrusting thing. But I got the hang of it quickly enough.
At the end of it all, as we all lay together, I said, "I love you both!"
Master said, "I love you both, too."
And Lupa chimed in, "I love you both too!"
