I awake slowly. First I become aware of the surrounding sounds, our neighbor mowing their lawn and a robin singing in the trees. Then the sensation of bedsheets underneath me makes its way to my brain. I open my eyes to see my bedroom ceiling above me and light streaming through my windows. The clock sitting on my bedside table reads 8:26 in the morning.
I think of the night before, my dad mercilessly pummeling my behind and the bulge in my stomach. As I remember, my hand unconsciously moves down to rest on my stomach, and my whole body freezes.
I slowly lift my head off the pillow and slide my vision down towards my feet...
And see a massive, swollen mountain staring back at me.
A scream bursts from my mouth and try to leap up but only manages a squirm. My mind races as my hands probe my belly. I try again to sit up in bed, only to have my muscles fail me a second time. I realize my stomach has become so heavy that I can't lift myself from the bed.
I need to eject my dad's liquid from my body.
My hands press down on my new girth, only to sink in like a pillow. I clench my inner muscles, trying to squeeze, but I'm met with an intense pressure in my anus I haven't noticed yet. When I extend my hand, I discover a rubber disk covering my hole. I pull hard while holding onto the edge, but only feel the pressure rise sharply. I grunt and collapse back onto the blankets.
As I lay for what feels like hours, I take in more of my body. My dad most have finished washing me in the shower after I passed out because my skin feels clean. On my top I'm wearing a white tank top, of course hiked up because it can't fit over my stomach, and on my bottom I'm wearing a pair of my sports jock straps with the butt out. I guess my dad dressed me as well.
After a while, there's a soft knock on my door.
"Come in." I mumble.
The door nudges open and my dads head pokes in.
"Hey there, sleepy head." he smiles. He's wearing a white tank top like me, with only tight black underwear below. His soft dong is imprinted down the leg of the underwear and its head pokes out the end.
"What's going on!" I yell louder than intended, "What happened last night? Why is my tummy like this? Why is there something in my butt I can't get out?"
He chuckles, "Lot of questions there, let's see, well our celebration is what's going on, I told you it would. That kind of answers the second question. Your tummy is all filled up with something called my Cum and that's a Butt plug in your butt to keep you from losing any."
He rubs his hands together, "It's about time I take that out though, there's still so much party to go."
"What are you talking about?"
He doesn't reply, but holds up a small box he had been holding and presses a button on it. Immediately, all the pressure in my backside releases and I let out a sudden deep breath. My dad reaches over and slips out the plug and throws it to the floor. He sits down on the edge of the bed as liquid starts dripping out of me.
"Let's speed this process up, shall we." he says briskly, spreading my legs wide apart. He places both his hands firmly on my belly, and they sink deep into the mound as he presses down. I moan loudly, and my eyes roll back as gallons of his Cum gush out my butt. The white goo floods the V in between my open legs and flows off the end of the bed.
It takes over a minute, but finally the majority of the Cum is out of me and my middle looks almost normal.
