You handle business…

You groan as you wake up. Your massive belly rests to your side. You can actually hug it, and you rub your morning wood against it. Your bed frame starts squeaking as you masturbate with your belly. You might have been embarrassed before to let your bed squeak so obviously, but now…

“Fuck…. Mom! Uugghh! Fill my belly!” You shout as you cum. “Give me your cum! Yesss!” Your spray sticks to your skin.

“Having fun up there?” Mom calls from the first floor. “Am I in your fantasies now?”

You keep up the shouting even after you finish, pretending you didn’t hear her. “Mmmm, look at my belly! You are making me fat, but I love it!”

You hear a startled “Oh!” as she thought you were finished.

“I’m getting such a big butt, I can’t fit in my clothes! I’m going to have to switch to a kilt for work and pretend it’s religious! Hope there aren’t any strong winds…”

“Oh…” you hear from below. You stop there and still your movements on the bed and get up. There are a few moments of silence. “You finished?” Mom calls again.

“All done, Mom! What’s up?” You call and manage not to giggle.

“Just heard you calling my name,” Mom replies.

“Yeah, sorry about that! I was just masturbating thinking about you! How much you fill my belly, and how big my butt is getting. Do you like big butts, Mom? I think I’m going to be growing steadily if we keep this up!”

“I love big butts! You’ve seen how big mine is!”

“And it’s beautiful! Just wanted to keep you updated! I’ll be down in a little bit…”

*****

You see Mom eating breakfast like a hog when you get down there. A few waffles are set aside for you, with butter on top. You know it’s made from her breast milk, like all dairy products in your house.

“Morning, Mom! I feel refreshed!”

“Sounds like you had a fun time up there! Mommy is in your fantasies now?” She asks again, not knowing you heard the first time. She must really want to know.

“Yeah, Mom. Of course!” Under your breath, but loud enough so Mom can hear, you add, “The things we do in my head…”

“What was that last part?”

“That I think about you even when I’m in bed?” You smirk internally. Your Mom is so flustered her lie radar is offline.

“Oh, right! Well I heard that, silly! We on for tonight again? All good in the bathroom?”

“Yes, surprisingly,” you answer honestly. It’s taking a little longer, but much less than the first time. I just let the pressure push itself out and relax my butthole.”

“Good. I don’t want to make you late just because I can’t keep it in my pants.” Mom smiles at you.

“Let me know when they make pants big enough to fit that log in…and also when they make them big enough for my butt…” you add, showing your mom even your casual pants are tight in the rear.

“*That* I can fix. I’ll order some stuff on one of those shopping apps for you.”

“Thanks, Mom! I’ll see you after work!”
