Mother Daughter bonding time

Back in our room I thought that it was suspiciously quiet now knowing that Sarah was in the connected bathroom with my wife. It only sounded like she was taking a bath, but just cracking the door let me hear some frenzied muffled moans.

She must have heard something because she spoke. "Mhpf~ John? That you?" There was a quick splash of water as they must have hidden themselves. So I put on my 'I just want to go back to bed face' and stepped in mumbling an affirmative it was just me. "Mhnn~ Well- Haa~ Wait, John you can't..." Sarah wasn't even trying to hide herself though with the heavy amount of bubbles in the bath she whispered something to my wife as she seemed to be laying back. I didn't quite hear what was said but I can imagine as she said something about Katie. Neither of them were bothered by their breasts on display, though my wife didn't seem to notice that both of theirs seemed to be quite hard as the moment seemed to excite them more.

Sarah seemed to be ready for me to enter as she took it apon herself to explain what they were doing. "I was having trouble sleeping. We were just helping each other relax by washing each other." She took that moment to pretend she was washing her by placing a mass of bubbles over my wife breasts. The way she subtly twitched and struggled to keep her voice in betrayed what was actually happening under those bubbles. Apparently I was staring too much as my wife spoke with a shaky voice before attempting to close the curtain. "J-Just f-finish Quic-kly Pl-lease~"

She tried but wasn't able to close it fully I could still see Sarah. Who was still acting casually occasionally glancing at me. I went through the motions of using the toilet before letting out an exaggerated yawn as I flushed and left the room with a quick peak back. Sarah was already leaning over the lounging form of my wife with her legs locked behind her waist. I got to see her thrusting again just before the door closed and my wife's muffled moaning response.

I really was tired though, I let out an actual yawn as I made my way back to the bed and fell asleep quite quickly.
