Derick moans happily as her boobs jumped outward with another burst of cum, her areolas swelling and forming small mounds which her thick nipples stuck out from. She tweaked them happily as another stream filled her butt, and she felt it push her up from the bed a bit. "Oh gooooood~~ I'm turning into a giant ball of cum~~" she moaned pleasurably, rubbing her medicine-ball sized tummy happily.
The dick was getting warn out from cumming so hard and so often in dericks pussy, and it needed to rest and recuperate so it tried to start moving back out her vaginal passage.
Derick didnt feel ir happening at first, she was to engrossed in pleasure, but the cum started to be filling her less and less frequently. She craned her neck only to see her body blocking her view. She smiled as ahe jiggled her belly, hearing the cum slosh inside. She felt the dick coil into a hard lump and she moaned, reaching down to her crotch. Just above her lips was a solid mass, and she felt it slowly uncoiling... it was starting to push her lips apart! "Oh hell no, I'm not letting you leave!" She grunted, forcing her lips shut and preventing it's escape. She grabbed the lump and rubbed and masaged it, her pussy muscles contracting and masaging, pushing the hard lump of dick towards her cervix again. The dick rappidly swelled to combat this, but it was no use as her stretchy opening, fueld by desire for more cum, sucked the dick in. She arched her back and screamed as ahe felt it pass her cervix, the dick completely inside her once again, and the opening sealed shut behind it. The big balls were now pulled taught against her crotch, and she squeezed them to force more cum out of the dick, but it wasnt giving her any! "Please.... I NEED it!" She flipped onto her stomach and sloshed around, hoping to awaken the dick whichs rubbornly refused to cum. Now what?
