The bath

You slide into the bath, although it's big enough that it might qualify as a small pool. It's hot like it should be though. There's raised area closer to the edge, so you sit down.

"I knew it." Sarah says, "They float."

"They look like pillows." Riley says, and hops in after you, and you're surprised when she sits down on your lap and leans back, resting her head on your breasts. "Ah, that's nice and soft."

Anastasia gets in, and proudly exclaims "Mine float some too!"

Sarah gets in last, slipping next to you. You remember that she and Riley give you the vibe of old friends, and decide to ask her about making Riley get off of your lap.

"Hey," you whisper to her, "You know Riley, right?"

"Since we were little, yeah." she whispers back.

"Can you tell me how to get her off?"

"Easy. Her tits are tiny, but really sensitive. If you rub them a little, she'll get off for sure."

You want her off, but you feel a little odd about touching her chest. Then again, she obviously doesn't have the same problem with you.
