Derick gasped in pleasure as her vaginal passageway flexed hugrily, and she felt the large warm ball press into her sex. She gently pushed it, feeling herself begin to stretch around the nut much to her pleasure. She groaned as her pussy was already tight, her muscles gently trying to coax the large ball inside, but it was steuggling due to the cheer size. So, she carefully lowered herself onto the ball, and began to slowly put her full weight on it, and the feeling was indescribable. She screamed as the smooth orb was forced in, her puasy stretching impossibly wide as she tried to fit the enormous ball into her vagina. She began to bounce on it with growing levels of force as she groaned and grabbed her nipples, her rather large clit rubbing against it. She was starting to feel the pressure on the inside of her hips, they wernt wide enough to hold such a large mass. The ball was about one quarter into her and her vagina had latched on, trying to pull it inside and make it cum, but not making any progress woth it stucm on her hips. She knew exactly how to solve her problem. Reaching down with both hands she began to massage the ball, feeling it's warm girth pulse as she rubbed it. Her vagina muscles started a co-ordinated movement with her hands as she dragged them up frlm the bottom to her cunt, and she felt her plan starting to work. She felt the tubes connecting the dick to the balls harden in her vagina and a familiar hot sensation filled her as she quickly wrapped her arms around her stlmach and breasts. She felt her hips and ass explode outwards, triggering a massive orgasm and causing dericm to fall prone onto her belly, face buried in her clea agr as the feeling of her over-inflated body and stuffed pussy becoming her main desire as pleasure wracked her body. As hwr hips rolled outwards, the ball slid further inside, her spasming vagina managing to use some of the cum to stretch easier (slightly) around it, amd finally she felt her cervix get forced open as the ball mare the transition from vagina to womb. She moaned into her tits as her tightest opening was forced to open for the enormous sphere she could feel with every inch of her swueezing pussy. After a solid half hour of pleasure a loud pop resonated through her as her cervix slammed shut on the ball, which inflated her womb an extra five centimeters. She could feel the dick and ball resting in her womb as she rubbed her stomach, quietly moaning and reveling in the afterglow of what she just did. Hee puasy had swollen tk twice it's size, and the pufdy lips were clamoed tightly shut once again. She heaved ontk her much larger cushion of a butt, and rubbed her hip. It jutted out a solid 10 extra centimeters on each side, nd she could feel her pulsing and contracting vagina within. She grinned as she felt the other ball against her thighs, she knew what came next...
