Kako has a plan...again!

You know you should just relax your butthole muscles and drain yourself, but then you would probably have to go through this all over again.
"I honestly didn't take this into my calculations. I'm sorry about that," Kako tells you. "This new shirt keeps your center of gravity too high. You look really yummy. Did I tell you that already? Here, let's help you over to the sofa. That's it, just bend over the arm and let that heavy front rest on the seat. Hehe, you are just like Mrs. Barstone...except she can walk! Well you are bigger, though. That's my fault. You wait here. Give me like an hour, I'll have you up on your feet in no time!"
Kako runs off before you can protest. Well...you have an hour. You might as well check out the new goods. You explore every inch of your front. You pay special attention to your belly. It takes a long time since it is so big. The new bra is nice too. From this position, the part of your belly protruding from your shirt hangs down and your titflesh flows together. That would make a killer tittyfuck. By the time you think that it would be nice if Kako would try out your cleavage, she returns.
"Hey Kako, tittyfuck me. I bet this would get you off quick!"
"Oh, I have plans to set in motion." She seems tempted, though.
"Just a quick one? I want to see what it is like," you tempt her as you shake your chest.
"But...just a little, I suppose," she tells you as she hikes up her dress in the front and fishes her cock from her panties. You rub it a bit and lick the tip until you taste a bit of sour precum. When you coat the first foot or so, you lift your chin and guide the end to your cleavage. She pushes until she nudges the top of your swollen belly, then pulls back. She repeats it a few times.
"Crap, this is really good," she comments. "I better stop now!" Suddenly she tries to withdraw, but you hold her there in between your bosoms. You are enjoying the feeling of a tittyfuck at this angle. "Oh well..." Kako sighs and gives your chest a few more long, hard thrusts before she cums.
"Oooh, that's a good feeling, getting your cum squirted between my boobs!" You smile up at her. She smiles back weakly and covers her eyes with her hand as she finishes her short orgasm. When you look down, you see more of Kako's cock is covered than before. As you continue to watch, more is swallowed up by your chest. Wait...sour precum...short orgasm...more growth hormones! When you hang your head, your chin rests in your cleavage.
