You probably shouldn't...

"Actually, I'm feeling really full, Kako. Maybe I should pass." You heft your cum-filled belly in your hands. "You filled this from both ends already."

"Aww...comon. You can take one more, can't you? After this one I promise you can walk around at that size for the rest of the day. I won't even bug you about it. Scout's honor!" You know you probably shouldn't; you are feeling overfull already.

"Ah, fine. One more time," you say in surrender. "I'm in charge this time though. Lay down and hold up some of that monster. I'm gonna show you what it's like having a big belly slam into you over and over. And you better be jacking me good. I need to get off too, and no stopping because your arms hurt from having my belly land on them too much."

"Yessir, ready to get ridden and slammed by your distended belly," Kako says as she assumes the position. You hop on facing her, taking a bit greater length than before as you sit hard on her. She immediately has her hands on your dick. You rise and fall, and your belly landing knocks the wind out of her. She keeps to her promise and continues to jack you without complaint. You run your fingers along the rim of your obscenely stretched butthole. You wonder at how you ever managed this girth. Her shaft grows, and you know you are about to see your belly balloon out. You sit on her hard, and rub her balls, coaxing out the king of all loads. You secretly love preggo porn, and having your own preggo belly is just too kinky to pass up. You start shooting cum at the thought. It sprays over Kako's massive mounds. You then feel a blast of heat inside of you, her cum going into you with great ****. It is so big the next one catches the tail end of the first, and it feels almost like a steady stream. Your hands are on your belly as you balloon out, pure amazement in your eyes. You end up looking like your neighbor Mrs. Barstone before she had her triplets. Kako plugs your ass as you get up. Your belly jiggles as you walk. It ripples slightly as you hop in front of a mirror.

"Don't entice me like that! I will keep pumping cum in you, and after some point it has got to come out one end or the other," she chides while wagging the end of her dick at you.
