"First let's resolve your lack of thick cum." Her activation word cum caused me to spew out clear liquid from my caged cock. "Open wide, unless you want me to use the gag ring." Rachel grabbed me by the hair, forcefully thrusting her pink strap-on past my lips.
In between my gagging, as the dildo reached the bottom of my throat, I tried my best to think about what she may have meant. Her treatment made me lose focus on my penis as I felt the chastity cage tighten up even further, shrinking to three inches in length. My fear was the cage continuously pushing back my penis until it literally became a girl's clit, receding into my body. That would cause my erection to be internal, not able to be seen as a proper dick at that point.
Rachel used her speed magic now that the deals were over, treating my mouth as a second pussy to my ass. The strap-ons lubricant made her speed bearable, "Get ready to swallow, bitch." Rachel panted, increasing her pace another notch. "Not like you have a choice anyway." I didn't know what to expect since my mouth was filled full of her massive dildo.
The moment she stopped at one final thrust, stabbing at the base to my teeth, a warm stream of dense fluid burst forth from the strap-on's tip. Other than the lubrication, this never happened before. It was like she said, and regardless if I wanted to swallow or not, every drop of the thick jizz like liquid entered directly into my belly. It continued long enough to send me gasping for air, caressing the sides of her hip frantically as a means to tell her to pull it out.
She did so on her own time and with a pop her rubbery dildo had left my throat. There was a lingering stickiness on the walls of my throat, almost like a constant reminder of the jizz slowly finding its way down to my stomach.
"You should be thanking me for supplying you with some essential vitamins. That will help with your pitiful sperm count." Rachel stroked her strap-on with her gloved hand like she could personally feel it. "There's also a surprise, you'll find out about it later on." She enjoyed keeping me in suspense with her evil schemes. Every time there was something new to learn from her twisted toys.
"What did you do?" I was already accusing her of something bad.
"Cum for me and you'll find out." The thirty-second time limit for the deactivation on the buttplug had long ended as her keyword sent me shivering more than usual. Instead of leaking translucent cum like I was running on empty, my caged penis actually managed to spray a heavy line of sperm onto the white bedsheets. "What do you think, cumslut?" The unfamiliar intensity was too much to handle for her to continue the onslaught of her keyword.
I instantly leaned over to dig my face into the blanket, unconcerned with how it looked. "Aww, that's my good boy. How does your cum taste?" I managed to deactivate the buttplug's prostate arousal before her next sentence.
It was beginning to set in though, the way she asked her particular question. I had realized too late, knowing full well there was some side effect from eating my altered mess.
"Tell me already!" I hated being kept in suspense and at least wanted to know what I had gotten myself into.
"I made it so your cum eating becomes productive." Rachel snickered. "Eating the enhanced cum is like taking a form of estrogen. It'll actually turn you more into my ideal sissy-slut, both mentally and physically." I didn't like the sound of that, and I tried to figure out a way to escape the unacceptable fate.
"Don't worry though, as long as you can hold back from being such a cum eating slut. You won't run into any changes." It sounded like there was a possible out, an escape route provided to me. The effects must not be instant and require multiple doses to cause any real damage.
The wide grin on her lips was all too familiar to me, it was her knowing my defeat ahead of time and enjoying the process of my mind crumbling even further into despair. That was the kind of face I came to learn from her.
"How many times does it take to have any visible effect?" I needed to know a concrete number to work with, even if I had to subtract from it, out of distrust of her not telling the whole truth.
"Hmm... probably around twenty-times, within a short enough time frame would be enough to cause sudden changes to take place." She took her time to think about it, seeming like she really didn't know. "It may vary depending on the person though. If I were you I'd just come to terms with being my slave, mentally that is." All of the things she had me wrapped around in were worse than a simple slave seal, or at least felt that way.
"I swear, I won't let you reach such an outcome." For once she saw true defiance in my eyes and played it off with a simple tease.
"Did you say come?" She smirked as I felt the rubbery material of her glove caress my cheek. "Kind of hard to act threatening when cumming full blast like that from only the word cum." I couldn't hold back from her barrage of activations, with the thirty-second timer seeming nonexistent in between phases.
I ended up downing another thick stream of sperm, the bracelet seemed to know exactly the proper amount of cum that I needed to eat, only deactivating the buttplug when its conditions were satisfied.
I believed it was right to half her estimation to ten times, which meant I only had nine left until my safety at maintaining a boy's body was at risk. I truly meant good on my threat and made sure to have an out, even if I never expected things to turn into such a clusterfuck. I could always rely on my fear ability, it had already saved me once with Ella's servants and that crazy hypno orgy they were trying to force down my throat.
