OK

"Yeah, I'll let you do that," you tell her as you slowly pull yourself off of her. You have a good idea that once she is out of you, you will have only a few seconds. You can feel how loose you are already, and know you will be gaping so wide that Kako will be cumming soon after she sees that. "Kako, I am gaping so wide already, I can feel it. I'm not even halfway out yet, but I can't tighten my muscles enough to squeeze you."
"Oh, you miss me already? Don't worry, I'll climb up your butt again after this! Even with this fat belly!"
"Yeah that's good...and my thighs are so thick now, and my butt too...I could carry you in me for a long time!" You finally pull off of her, and turn around and impale your cleavage on her dick until it comes out of the top and bumps you in the chin.
"Wow! So tight! Can you-" You use your arms to push your tits ogether tighter. "Oooh, it's better than I had hoped! You knew just what I was thinking!" Considering the size of her dick, she displaces a lot of titflesh. Given your own size, she doesn't press against your chest, but glides fully surrounded by your breasts. "Now, I know what you are thinking. Just pull up a bit so my cockhead rests between your lovely bosoms." You pull yourself up a bit, so her head rests in the middle. Then she starts cumming. Like a low-presure oil gyser, cum pours up from between your titties. It flows out over your skin.
