A day had passed since Ty became Titty. She had gotten used to her girl body for the most part, albeit she now was notably worse at enjoying the daily sex with her share of bitches. For some reason, her cock just didn't let her feel good enough to cum on its own. Every time she had to resort to tugging her nipples and spraying milk all over her current bitch to get off. This was deeply concerning for her. Why was her cock no longer enough? It felt just as good as before. So what changed? Was it because she now had tits? She doubted it.
It was already late a night. Her last bitch came and went about 2 hours ago, and Rachel was just finishing up with her own half of their daily load. Titty ended up doing most of it today sine Rachel was too submissive to actually do it most of the time. It was only after Titty has demanded her to, was she finally able to cum inside her bitch.
Titty was slumped against a wall, still trying to figure out her erection issues when Rachel confidently approached her, fully erect. "Well Titty bitch, today really sucked. Me being hyper submissive to a pussy of a mate like you isn't a great setup for fucking bitches. Seriously, next time you have to control me, demand from me, make me submit."
Titty was only half paying attention though. When she had heard Rachel approaching, her thoughts became dominated with desires to be fucked again by Rachel's bull cock. "Hello? Titty? You in there? Asked an annoyed Rachel, wqving her hand infront of Titty's face. This brought Titty back into reality from her daydream.
"Hhhhh? Oh, uh, yeah.... sorry."
"Hmmph" grunted Rachel.
"Hey. Can I ask you a question? You have always been a girl so maybe you know. But uh, why cant I cum from pleasuring just my dick anymore?" Asked a desperate Titty. Try as she might, not a single answer could be reached for her unsatisfied cock.
"It because you are now my bitch. And me being hyper submissive will not change that fact."
"What do you mean?" Asked Titty, now confused by Rachel's reasoning.
"Lets see.... basically your current body belongs to me now. You may mentally be in control of your body, but you are subconsciously accepting being a girl, and have become submissive to my cock. It is why you currently cant look away and are drooling a bit with anticipation. In other words, you can only get off by the hard way by doing a lot of self pleasure, or easily by impaling your pussy on this massive bull cock."
Titty knew at that moment what Rachel said was right. She could just tell, but didn't know how to proceedin the future. "So what do I do?"
"That's easy. Never unmount my cock ever again." Grinned Rachel as she forcfully picked up Titty with ease, and stuck her on the tip of her cock, while pushing her down as it slid into her wet pussy. Titty couldn't even say a word or complain as she finally was feeling the release she desperately wanted.
"Hey master are you there?" Called out Rachel.
"What? To think you had the courage to call your master to your room. Hahahaha, amazing. I knew making you sometimes become a dominant being who would do anything to improve her work was the right choice. Tell me, what will help you become more efficient?"
"Good, so you are here. Look, I need to somehow strap this one on my cock permanently. Got anything for that?"
"Hehe, just the thing." He said as he produced a bottle of liquid out of thin air. Smear this on the inside her pussy. Then the next thing that enters it will become trapped inside."
"Excellent, that will work just fine." Said Rachel as she took the bottle.
"It seems your origional DNA is taking well to the added bull DNA. Your new horns are comming in nicely. Shouldnt be long until that one starts getting altered too from taking so much of your cum. I think she may even be already growing an udder, or is that just all of your cum?" Commented Master.
"It definitely is the start of her udder. Though most of it is my cum."
Titty had been set on the ground for a bit since she had passed out from earlier, so she missed this. Rachel finished rubbing the liquid on the inside of Titty's pussy and one again, set Titty on her cock, this time noting her pussy lips clamped down tightly, but not tight to where it was uncomfortable. She just would never be able to slide her enlarged gland out of her anymore. She was forever going to fuck Titty. And Titty would be the one to fuck the bitches, while being fucked at the same time. It was sure to rapidly increase their productivity.
