Chris Declines, Sam Toys With Him Some More

“I-I think I’ll pass.” Chris eventually said. Part of him wanted to, another part of him knew it was wrong, and a very small part of him didn’t want to hurt his hot dad’s feelings for saying no.

It was all just a bit too weird.

“Oh well. The offer stands in case you change your mind.” Sam said with a sigh and a roll of her eyes, but she didn’t stop smiling. “You’re really missing out. I stayed up all night playing with these girls, among other things.”

The sexy sound of her silky smooth voice saying those things while she carefully massaged her big tits was having an effect on Chris, more specifically his raging erection, which was thankfully tucked and out of sight.

Shit, maybe he should just take her up on the offer, he briefly thought to himself.

“So, want me to change anything with the app?” Sam asked, eager as can be as she pulled her phone out from between her cleavage. “All I’ve done is mess around with my body, but it can pretty much do anything you can imagine.”

“Well, I don’t know… I mean, yeah, but-“

“Don’t worry, I know just the thing.” Sam said, already typing into her phone.

This time, Chris couldn’t see the screen, so he was suddenly and understandably paranoid.

“Hang on a second dad, what are you-?”

Chris was interrupted as his entire body buzzed with sensation, but only for a moment. He gasped and flinched, feeling dizzy for a few short moments afterwards.

“Damn, dad. Give me a better warning next time.” He said, slowly sitting upright on the couch and examining himself.

Nothing looked different. Chris was still his average and slender self.

“What did you do?”

Sam giggled, then got up on her knees and faced her son on the couch.

"Look at my chest." She said, turning her torso from side to side to gently shake them.

Chris' eyes wouldn't have been able to avert themselves even if he wanted them to, but he became flushed once again as he nervously glanced between her jiggling tits and her smiling face.

"Now, imagine them getting bigger."

"Huh?" He asked, but unconsciously did as his father said. "Why would I-...?"

With a gasping moan, Sam bit down on her lip at the sensations that followed, and Chris' jaw dropped as he watched his father's perky melons begin to swell right before their eyes, bubbling outwards underneath the strain of her stretching tank top.

"Holy shit!" They both said. Sam moaned it, while Chris whispered it.

Too stunned to look away, Chris continued to stare, and they kept growing bigger and bigger. They swelled from ripe oranges to grapefruits, then from grapefruits to cantaloupes, then from cantaloupes to watermelons. By this point, her tank top had been pushed to its limit, and the growth stopped when the straps broke and her tits came bouncing and jiggling out to freedom.

Huge was an understatement. They were massive, almost perfectly round like a set of implants, extremely full, and were sloshing around with enough weight to knock off Sam's balance.

"Oh wow!" Sam laughed through deep breaths, visibly flushed from the intense sensation of her breasts growing along with them exploding from her shirt. "Hahah, this is so cool!"

Chris was virtually hypnotized by the sight of her pumpkin tits jiggling and sloshing around as her upper body wobbled around in every direction that those supple mammoths were pulling her towards.

"That was so cool." Chris whispered, his mind reeling with possibilities of how he could entertain himself with this power.

So much so that he needed to slap his face to sober up and remind himself that this person in front of him was, deep down, his dad.
