"A two? Not awful, Player Cosima. You're on body modification."
"Oh god..." she whined, sighing.
"Hey, as the only player who hasn't been changed so far, you should be happy with yourself, Player Cosima. It's rare that someone makes it past turn one without something happening to them."
"Still, after what happened to Rachel and Quinn, I'm sorta afraid..."
"You know, Player Cosima, I figured out your problem. You're simply not turned on enough to enjoy it. Therefore, your change is this: your pussy can stretch to accommodate any size and, to speed things up, you're going to be insanely turned on until you bring yourself to orgasm."
Due to the subtle nature of this change, Cosima's transformation wasn't immediately apparent. Her body grew no additions, like Alexis's new dick, nor did it change forms, like Rachel's stint as a bra. The only real way to test the change was to give her new genitals a run through which, for obvious reasons, she was in no hurry to do so. In fact, the only noticeable changer was in her demeanor. A fiery passion had exploded in her panties, catching the girl off guard. She brushed her thighs together sheepishly, awkwardly fighting off her raging libido. It worked, surprisingly, allowing Cosima to keep her dignity for the time being.
"Are you kidding?" Alexis asked with a grin. "Come on, Cos', you can't rip us off like that!"
"W-what do you mean?" Cosima replied, barely able to talk.
"You can't be a baby! You gotta embrace the change like me and Rach' did. Heck, Quinn enjoyed it more than you."
"Sorry Alexis, I-I'm just too embarrassed to do that kinda thing in f-front of you guys."
"Oh, in that case, lemme help ya."
Alexis had already popped out of her seat before Cosima could even begin to protest. She marched toward her sexual frustrated step-sister, but not before dragging Ryan along with her. She was annoyed with him for much the same reason. As the two arrived, Cosima found herself unable to do anything but squirm in her seat. Facing no resistance, Alexis took it as a sign to start stripping the girl of her pants and underwear, which she did in no time.
Ryan was next. He too was focused more on his horniness than anything else, allowing Alexis a free pass at removing his pants. As she slid them down, her eyes met his swollen sack. She was taken aback. Ryan's punishment for refusing the dare had been more severe than she had imagined. Curious, she reached forward and lightly squeezed it.
That feminine touch was all that it took to push him over the edge. Though it was his twin sister, his body simply didn't care. His cock became rock hard and his mind became flooded with dirty thoughts. He was tired of holding back his desires any longer. His eyes darted around, looking for relief for his aching member, when they locked onto Cosima's half naked form. He could tell from her panting and the moistness beneath her crotch that she was as turned on as he.
Seeing that as all the permission he needed, he lunged forward and scooped her from the seat. With great vigor, he slammed Cosima down onto his erect member. Her tight virgin pussy effortlessly stretched to accommodate it, clinging to it light a glove. In unison, the two moaned in relief. Alexis, watching from the sidelines, laughed maniacally. Her plan had worked; she had managed to get the two prudes to indulged in their transformations.
Not one to be left out, Alexis chose to capitalize on the situation. Approaching her suspended step-sister from behind, she jammed her own knotted member inside, brushing against Ryan's. Just like with his, Cosima's snatch stretched to the new arrival. Cosima's once pleasant moans evolved into stilted screams. It was one thing to have Ryan's cock, but Alexis's too? And knotted, to boot? It was simply too much pleasure for the girl to handle.
As the twins stood there, thrusting in unison, it suddenly hit Alexis that it was now her turn. Not one to hold up the game, she reached toward the table, just barely reaching the die. Without even looking, she tossed it, more concerned with giving Cosima the time of her life than whatever was going to happen to her. It landed on five.
"Five it is, Player Rachel. You're on..."
