Then the rumbling started again, only this time the gas left from the other end. A tiny ‘poot’ sounded from Jenny’s giant rump and before she could get embarrassed, the mass in her butt moved back up against, only this time it kept going. One second Jenny’s belly sprang back out, hitting Brad in the face and throwing him to the floor, and the next it was moving to her chest. Jenny squealed as she felt her blue metal top burst open to let her rapidly growing breasts fly out. Brad stared up with his mouth open as he saw the biggest set of knockers he had ever seen. He thought he could cry tears of joy, until they kept growing, getting bigger and bigger until Jenny toppled over, chest first right onto Brad. Two six foot wide breasts slapped down on Brad, burying him completely.

“Brad!” Jenny screamed as she struggled to lift her size Triple-Z breasts off her best friend. They were like two miniature zeppelins coming out of her chest, each weight several hundred pounds and as soft as fresh dough. She couldn’t see Brad, but she could feel him moving slightly against her massive white knockers, which was not too bad of a feeling. Her face went bright red as her sensitive breasts vibrated with Brad’s futile attempts to get up. The sensations nearly made Jenny stop, but remembering her friend could be in danger made her act fast. Grabbing the underside of her breasts, she lifted them up off Brad. They wobbled in her arms as she lifted them like jello. Falling back, Jenny sat on her deflated rump, her breasts slapping onto the ground in front of a still prone Brad.

“Are you okay Brad?!” Jenny checked, worried that Brad wasn’t saying anything or moving. She couldn’t see his face, but if she could she would have seen the big, happy smile on his face. He had been crushed under those breasts, but he had been crushed under breasts; that was every guy’s dream. He had felt their soft weight pushing down on every inch of his body. He still had shivers from feeling the underside jiggle against his face. Tuck, who had backed away the second Jenny became an E-Cup, crawled over to his brother, not to check on him, but instead to tease him.

“Bro, you just got to second base with Jenny.”

Brad was too happy to be upset about Tuck’s comment or bothered about his brother knowing so much. Then at that moment, Jenny started rumbling again. Brad sat up and stared at her as the mass inside her body moved again. Jenny met Brad’s eyes, silencing wondering what was going to happen next to her body. No one knew as the mass moved from her breasts to somewhere else in her body.
