Just surprised.

"What have you done?" Mrs. Barstone is stunned.
"Made us sexier, of course," Judy tells her.
"Yea Mom stop freaking out!" Violet chimes in.
"But Violet, look at your butt...it's so big! And you have one of our host's gigantic breasts in it too!"
"This is just the start. It's gonna get bigger...lots bigger! And then I'm gonna have the biggest belly too!"
"Oh my..." is all the mother says.
"You set a bad example for us Mom!" Judy tells her.
"Yea, Mom! You are all big."
"She is. I'm gonna take her tits and belly up my ass. Lay down Mrs. Barstone," you command. "Hang on to my girls, girls," you tell them as you lift yourself up with your tits still in their asses to varying degrees.
"You're serious?" Mrs. Barstone lays on the floor.
"Yes, of course! Did you think these huge cheeks were just for show?" You smack one for show.
"What do I need to do?"
"Just get your milk flowing, and spray me with it." She does as you ask. The warm liquid squirts onto your cheeks. "Now, just hold them together," you tell her as you lower yourself.
"Oh," she moans with wonder as her large breasts part your massive cheeks and disappear. "Are you milking me?"
"Oh, you noticed! I love breastmilk, if you didn't know. This is a bit harder than I remember, I must be getting rusty."
When you finally bottom out, you start pulling yourself forward so you can encompass her large middle too.
"Last time I did this, there was a huge cock below the belly to help me stretch."
"You seem to be doing fine from here," she says as she pats your butt. "I never thought about this before, but I like it! Maybe, I might want a big cock of my own!"
"I don't think that's possible, but...I've just finished here," you say as your cheeks rest on the floor to either side of her.
"No, I mean it. My girls love big cocks, I love big cocks...I should have my own, right? You feel that way about these things. You have big milky breasts and a nice thick feminine figure."
