Nope, Amy returns.

You sit back down, and examine the dolls again. Blue is on all fours with her tail straight out. Red is sort of bent over looking at the hand print on her ass, her tail swollen.
You then hear the door open, and Amy comes back in, with lots of bags.
"Miss me? I got us lots of fun things. I'm gonna go give them a run through the wash, to make sure they don't shrink. Back in a min." She never stopped.
You tap your foot as she makes you wait again. Then after ten minutes or so she is back.
"You look a little different," she says thoughtfully.
"Your aereolas are showing," you point out.
"This thing is hard to keep situated with these things bouncing around." She just pulls the strings down under her breasts. "That's better. You look like you can use a bra too," she smirks.
Sure enough, you are sticking out in the chest area, already! That was fast.
"Yea, looks like they are coming in faster than I expected. They didn't say how long this would take. I hope you like them."
"Wait, rewind. What? Tits?"
"You haven't noticed yours? They are like twice as big!"
You then relate to her what happened while she was out. She has lots of questions, so many she changes the washer loads in the middle. When you finish, she sits there with her doll in her hand. Then goes off, saying she needs to change the wash again. She comes back after a bit, looking perplexed.
"So why did mine work for you?"
"No idea, but it really isn't a big deal. Is it?"
"No," she ponders, "I guess not."
"You can probably use mine too, for a little while."
"Ug, why is this so tight?!?" she exclaims suddenly. Amy quickly undoes her strapon to find a cock and balls, small, but there. "Wow, so it's true!"
"Look at our bellies, yours is twice as large."
She does look to have a definate protrusion now.
You pull her toward you as you sit on the couch, and feel it. Then you lick down to her cock. You put the inch long protrusion in between your lips and roll it between them.
"Ooooo, that's nice. This is good. Keep it up." She shakes as she presses your head to her. Then she cums, a few drops only.
"Now," you say as you guide her to sit beside you, "you can't shove it down my throat like that when it gets huge, got it?"
"Oh no, once it is huge, it's going up your butt!" She giggles. "Let's see how big you've gotten while I was gone."
You lay your butt across her lap. She slaps it with glee.
"Like it?"
"I'm going to find out in a moment," she says seductively as her hands wander between your cheeks. She easily slides one clenched fist into you, then the other. Then she pulls them apart. "Wow they worked you! Mmm, spacious. She leans down and kisses your butt. "I love it!" Then she starts licking it as she pulls your hole in all directions. "Look at you...so loose!"
"I wonder how long until we can use the dolls again," you smirk.
"How long has it been?"
"Well let's see. It was night when I got here, we got knocked up a few hours later, fooled around until late morning, you shopped all day while I was with them, then let's see, it's morning again. I'm not even tired! It's been so long since I slept!"
"That's right! I feel fine, though. Energetic, even!" Amy snatches the dolls, and hands you yours. "So how did you do it?"
"I just wished it was real," you get a mischeivious thought, "and licked its dick."
"OK, let's do it," Amy tells you. "I wish she was real." Amy puts the doll's dick between her lips and flicks her tongue over the tip.
