Author's note: This chapter ended up being a bit longer than the others, despite my best efforts. Content warnings: this chapter is chock full of bisexual/pansexual scenes and there is some very ambiguously described "water sports". If thats not your thing, feel free to keep scrolling. Thanks to everyone who has been enjoying these!

"You're my toy now," Destiny's soft voice penetrated my sleep as she whispered in my ear. Before I was fully awake, the partition in my mind was opened and I had become a mere thing for Destiny's use. My tongue unfurled and my muscles went completely limp as I embodied my identity as a toy. I opened my eyes but simply looked ahead into nothing. My slowly waking thoughts circled the usual identity drain and disappeared.
Somewhere in my mind, I was aware of where I was --the living room floor. Earlier, I had been compelled to kneel there and lick Destiny's beautiful asshole until she fell asleep for an afternoon nap on the couch. After that was accomplished, I too had fallen asleep in the floor beside her, blissfully recounting our adventures at the lab until those memories faded into dreams.
"Good toy," she praised, as she straddled my face and lowered her pussy onto my tongue. She was already completely nude after we arrived at home and I had automatically undressed as well since Slut doesn't wear clothes at home.
"Oh fuck," she whined as she began pleasuring herself using me. "I'm so glad you belong to me now."
"Just look at these!" She enthused as she put her hands on my chest. Through my haze, I felt her squeeze my growing tits and there was much less resistance to her grip than I expected. They were actually soft and fleshy and despite my mind's swirling thought drain, I was turned on by her touch. I was vaguely aware of the pain of my dick pressing against it's cage but my draining thoughts didn't allow me to dwell on the discomfort. She continued rocking her hips, rubbing my tongue across her clit and all the way to her asshole and back.
"God! Your body is going to be so hot! And it's fucking mine!" She moaned and then fell forward onto my body as her hips bucked with an orgasm on my tongue. Eventually her gyrating slowed to a stop. My spiraling thoughts briefly acknowledged the warmth of her body and the softness of her bare tits againsf me before they drained into nothing again. After she caught her breath, she sat next to me in the floor. I continued looking up at nothing.
"All of this..mine," she mused more quietly and ran her fingers over my tits again and down my body until she got to my caged dick. She put her hands all over my cage and massaged my exposed balls. I could feel an echo of the pain of my dick pressing furiously against it's restraint.
"I know you think you're lucky. You wouldn't have agreed to all this if you didn't. But I'm lucky too. I get this tongue.." she said and bent over and took my limp tongue into her mouth and sucked on it for a moment like she was giving my tongue a blowjob. "..and these tits, your ass, and even your cute little dicklet. But better than any of that..I get your mind."
"Be my Slut again," she said softly as she stared into my blank eyes. As my identity as Slut flooded back into my mind, she kissed me deeply. I regained control of my body, caressed her cheek, and continued the kiss she started. As our mouths separated once again, she sat back up and pulled my pill bottle from the nearby table.
"Time to re-up, my lovely Slut," she said in a kind of quiet excitement as she retrieved a pill from the container. She looked at me expectantly and I instinctively opened my mouth. She promptly popped the pill into my mouth. I swallowed it and sucked gently on her outstretched finger from where she had dropped the pill, looking into her eyes.
"Very good," she said with something like pride. My heart fluttered with her praise and she laid her head on my shoulder.
We laid there for a few moments, quietly enjoying each other's presence. I rubbed her back, something I somehow knew would make her feel good, and she lightly played with my chest. A question entered my brain. Something from early this morning when she put my cage back on. She had known a little too well exactly how the pieces fit together.
"So who wore a chastity cage for you?" The question was blurted out as soon as it took shape in my mind. She smiled warmly.
"A girlfriend I had when I was 18," she said. "She was trans, not unlike you. She didn't come out until after we had decided to just be friends. At the time, she was expressing herself by being submissive to me. She wanted me to keep her in chastity while I fucked guys and even while I let them fuck her."
"What happened?"
"Oh, we're still friends. It's just that now that she knows who she is, she doesn't need me like that. I was her outlet for figuring herself out. But she did more for me than she realized. I learned from being with her that I didn't want to be monogamous and that I liked having sexual power."
"You didn't always know that?" I asked. I found it hard to imagine a world where she didn't have people like me in the palm her hand using her sexuality.
"You do remember I was a child genius right?" She said and laughed. "When I was in my first year of college, I was still a minor. When I was getting to the age where most teens were having sex, I was studying science with adults."
"So how does Shawn fit into this then?"
"Oh, Shawn used to live in my neighborhood. We've been friends since we were kids. For the longest time he was basically the classic gay best friend. It wasn't until some drunken night when he finally caught up to me in college that he revealed he wasn't just gay. He liked women too and everything else in between."
"So that's when you started fucking?" I asked, still confused about how this relationship worked.
"I don't remember how exactly it happened, but somehow I learned that he has a big dick. I was horny and curious and I thought he might have a little crush on me. So I asked if he wanted to fuck as friends."
"As friends??" I asked. I was still not buying this.
"Yeah, we get each other off and then we just do regular bestie stuff like shopping, drinks, dancing, spa days..you know?"
"Slut doesn't understand. But that's okay," I said smiling and shaking my head. She smiled back and an awkward silence fell over us as we both tried to think of what to say next.
