Scarlett bent downwards to retrieve the gum, purposely shoving her big butt in Charlie's direction, this made him blush and fold his legs which were her exact intentions.
"Mom, your ass is huge!" Violet gasped, and stepped back, heavily breathing.
Scarlett giggled, "I see Charlie isn't the only one I'm driving crazy", she replied seductively.
Violet's mom stood up, turned around and slowly walked towards her daughter, looking her in the eye and smiling mischievously, implying she knew something Violet didn't. Charlie was in awe of Scarlett's sizeable behind, jiggling and wobbling as she walked away from him. Scarlett looked behind herself, at her ass and then back at Charlie, "you'll have your chance" she said laughing at him, his lust overtaking every cell in his body.
She immediately turned back to Violet, who was looking rather concerned, she had never seen her mother like this. "Mother, are you okay?" She asked worryingly.
"Sssshhhhhh" She put her finger over violets mouth, and then gently opened it with her tongue sticking out. Scarlett gently placed the gum on her tongue and closed her mouth.
"Just give this a chew, and you'll understand" she reassured Violet as she kissed her on the cheek, "it feels so good" her mother added. Violet starting chewing, and Scarlett stood back. Almost immediately, Violet starting feeling a tingling sensation in her upper chest, hips, ass and crotch area. This felt incredible. She looked up at her mother in excitement, Scarlett smiled back, so proud of her daughter becoming a women.
Violet moaned as her non-existant chest erupted into a pair of mature C-cup breasts. The tingling became even stronger in her legs, which caused her to fall to her knees and bend down. Violet's breathing became louder and heavier. The feeling was so good that she couldn't help but start giggling and laughing as the tingles took control of her body. The feeling intensified, she let out a loud moan and her ass started to expand. As this happened, violet's growing bottom unleashed a huge fart as her ass cheeks ballooned into a very fine and respectable sized rear-end.
The sight, sound and smell of Violet's inflating, farting ass drove Charlie insane.
As the gum finished its job, Violet started to breath slowly and eventually managed to stand up with her mothers help. Scarlett started laughing and giggling at her daughters reaction to the gum.
"Pee-yew!" She said smiling and laughing, "That was a bit stinky" She added playfully.
"How was that darling?" Scarlett said calmly. Violet, still recovering, eventually answered under her breath, "that was...so...good".
"I'm glad, and I'm so proud of you, you have officially become a women, any man will be at your mercy with those two melons on your chest, not to mention that absolute dump-truck you're carrying behind you" Scarlett slapped and rubbed her daughters newly expanded ass, tickling her daughter which made her chuckle. Violet could tell she had made her mother very happy.
The two laughed together for a short while, until they were interrupted.
"EKHEM!" a certain somebody exclaimed behind them.
"Guys, I'm still here" Charlie said.
Violet and Scarlett look at each other cheekily, as if they were reading each others minds. The two turned around to see Charlie, red-faced and a rather large bulge in his crotch area. The two goddesses placed their hands on their hips and stood before Charle.
"I see someones a little excited!" Violet said, smiling.
"You have both of us at your expense young man" said Scarlett. "You have a choice" Scarlett continued. "Which one of our big, fat, round, smelly asses, do you want to shove your face in first?"
