Feeling her embrace and smelling her hair. Soon enough, I took her up to my room. My bedroom was rather large. You had to pass through a sitting ro...m before entering the master bedroom. We set her stuff up and she unpacked her toiletries in the master bath. Back downstairs I made her a light lunch as we nervously chatted. There was a feeling of unease as both of us wondered what the next 22 hours would hold. But as always, I had a plan to work from; ready to adapt if the situation. I found that I had been holding my breath thru this last part and was feeling a bit dizzy myself.Tony then asked Rachel is there was anything about her mom she wanted changed and it wasn’t till he smiled at us that we realized he was k**ding. He asked us what we wanted to see Heather do and we got him to do the standard raising the arms thing and crawling around like a dog, she even barked for us. I was thinking how she must feel doing everything he said and being unable to resist. I was. The added sensation of Nans cunt in my face, with my tongue fucking her little asshole was enough to finally push me over that edge and into the biggest and longest orgasm I had ever had. Squirts of cum shot from my cunt as I cried a muffled yell into Nans cunt. I just kept licking and eating her out until my whole world went dark and I could just feel the pulses of the vibrator still in my cunt. Nothing on my body seemed to work and I could only watch as Megan and Nan now went at it on each. My mom and I almost looked like identical twins that day, even down to wearing the same sexy bikini swimsuit. Mom had just left to get more wine when John came into the house. Not knowing that my mother had left, he came up behind me thinking I was her. He proceeded to seduce and then fuck me while my dad was doing the same to his wife Kasey. It was so amazing what John had done to me thinking I was my mother. Then to top it off, Kasey started to lick my cum dripping pussy when my step-dad.
