A Tingle Down Below

At first, it just felt like a tingle down below, a strange sensation in her rear. "No!" She yelled in defiance, "That's not fair!" Ryan, post-euphoric but still horny as ever, was confused by his sister's sudden outburst. Then he saw his sister's pelvis start to rise and her hips start to expand. Claire grabbed her rear in desperation, trying to restrict the sudden change. "I did what it athked! I fucking gave my brother hand job!" Her crotch was on full display as Ryan watched her the fibers of her soaked white underwear strain and then snap around the girth of his sister's now massive booty. Her hairless pussy shimmered with the telltale signs of arousal. Her hips blossomed out at least 10 inches in circumference. Her waist remained skinny and she started to look like those Instagram ass models that had to have had surgery, but this was all real. It was juicy and round and firm in all the right ways. Claire struggled to get up before running to the restroom, hips spiraling in the perfect way beneath a miniskirt which was now too small to not appear from it.

"Well, she gets around but she's not a whore." said Ryan to Mia who was masturbating to Ryan as he still held his leaking cock.

"That was actually kind of hot, but how did that happen?"

"She jerked my cock, but in the end she gave me a blow job, not a handjob. I didn't think the box would be such a stickler for the rules... but now we know I guess." Mia and Ryan exchanged unchaste looks, almost ready to heat things up since Claire was taking so long to examine her ass. Ryan started to say, "Grow pen..."

"No!" Shouted Claire as she ran back in with her miniskirt pulled down to the reveal her hip bones in the front and hide her magnificent ass. She plopped back down and snatched up her panties. "I heard you guyth. We are moving on... and no, I will not tell you the exact number of people I slept with."

"I think you look hot Claire." Said Mia, "If that helps."

"Moving on!" Claire reiterated as she held out a hand to the box.

As if on call, it went Ding!.
