Even after they fucked each other, Bree and Kaitlyn cocks were still hard.
"Bree, you said you can control the size of your dick, didn't you?" Kaitlyn asked
"I said yes. Why?" Bree asked
"Because I want to see him much bigger. Let's test to see what size limit it can reach." Kaitlyn said
"You had a good idea, I will do just that." Bree said and started to slowly increase the size of her cock. Her stick quickly reached 2 feet, continued to grow past 3 feet, but when it reached 4 feet, Bree lost control of her body and her cock stopped growing.
"It got huge, so this is the size limit he can reach." Kaitlyn said
"I don't know, but it looks like I went into tutorial mode. Because of that, I lost all control over my body until an acquired ability from this size is demonstrated." Bree said. Then, Bree's body moved by itself so that it made the tip of her cock press the tip of Kaitlyn's cock. After straining a little, Kaitlyn's cock entered Bree's urethra.
"This is amazing, I never thought I could fuck a dick." Kaitlyn said
Bree regained control of her body, but decided to continue with the option shown and the two moved her body. She was loving having Kaitlyn fucking her dick.
It took a few more minutes before Kaitlyn came. Bree's balls grew a lot with the fucking Kaitlyn that was going in there. Only after Kaitlyn's orgasm ended and she pulled her cock out of the urethra did Bree come, shooting her and Kaitlyn's cum through her cock.
