You are sore.

You wake up and the moment you move you wish you hadn't. You are very sore. You don't even open your eyes. You feel Kako crawling on you, which is what woke you up.

"Feeling sore? Here I'll help..." she says before licking around your chest. It actually does help a lot. Damn good in fact. You need to have her do this more often. You really like it when she licks your nipples energetically.

Feeling more awake and also horny, you open your eyes to grab Kako to have her assume the position. Instead you just stare as Kako works the A cup tits that have grown on your chest.

"W-w-what..." you stammer. She takes her mouth off of your puffy left nipple to explain.

"Well, you said you wanted big milky preggo tits; this is how they start, as little A cups. But don't worry, I'm cooking up more hormones now. It just takes a while to concentate the volume. That's why before it only felt like a normal person's cum load instead of one of my normally massive ones."
