When Mira's cock stopped twitching, it aimed at her mouth and forced entry. She had to endure her mouth being stretched to the limit, almost hurting her, and soon she felt a hot liquid come out of the tip of her dick and go straight down her throat.
"I'm... Am I pissing by any chance?" Mira thought, but the rate at which the liquid came out was much slower than that of pissing, and the taste was nothing like it either. It was a very sweet liquid, but the flavor was like a mix of banana and strawberry. When the liquid fell into her stomach, a warmth quickly spread to the rest of her body. Instead of her belly filling with the liquid, her entire body grew at the same time that her skin darkened, gaining the tone of a permanent tan.
Mira felt a huge sense of accomplishment and Kiera watched in fear as the shemale grew to her final almost 9 feet tall. The Amazon shemale, upon finishing her transformation, her cock came out of her mouth and she looked at her body with an expression of contentment at what had happened, her cock quickly growing hard to its new 7 foot length.
Mira looked naughty at Kiera, who stepped back and asked "You don't want to do what I'm thinking, do you?"
"You can be sure I will do it." Mira said
"No way, your dick is now bigger than my entire body, there's no way it can fit." Kiera said
"Normally not, but something tells me that if it's with you it will work. I have a feeling that something else besides your sex has changed in you." Mira said
"No way, I don't want this, change me back to normal." Kiera said and backed away, but Mira caught her easily and laid her down
"Calm down, there's no need to be afraid. It's not bad to be on the receiving end, you'll see." Mira said
"That's what someone who got rid of their own pussy said and made me a girl." Kiera said
"I didn't get rid of my pussy forever, at least I don't think so, but knowing the possibility, I think I have the right to know the other side too." Mira said
Embarrassed, Kiera spread her legs and looked away as she said softly "I can't believe I'm letting you do this to me."
Mira pointed her huge dick against Kiera's pussy, but at first it was useless and just pushed the girl, and when she was against the wall, her entrance gave way.
Kiera's entire hips expanded to make way for the giant meat member, which entered surprisingly not without hurting her or causing any pain.
Mira continued pushing in, finding no resistance and not even feeling the presence of bones, it felt like her girlfriend was made of rubber and was stretching to mold herself to the dick inside her. The only interference was when her dick finished crossing Kiera's chest and reaching her throat from the inside, where instead of moving forward, Kiera's torso was stretched, in yet another demonstration of her enormous elasticity. Once she got it all in she fucked, increasing the pace, keeping the pace even when Kiera, not wanting to admit that she had done it, came.
Eventually Mira felt her orgasm coming, so she increased the pace until she stopped, pushing everything in and cumming, her seed leaving her watermelon-sized balls and filling Kiera's insides, which inflated like a human condom.
For Mira, she must have cum at least four times more than the previous time when her orgasm finally subsided. When she was done, she pulled out her cock, which now flaccid was long enough to have part of it resting on the floor. When she looked at Kiera, she saw that her girlfriend was slightly rounded, as if she was pregnant with a foal. Mira also saw a quantity of her own cum oozing out, and it had a purple glow.
