I collapsed on top of her as the last of my orgasm died down, leaving in its wake a very mushy junction of two crotches, the white fluid leaking out o...f her pussy even as I still remained in her. The two of us just looked into each other's eyes, and saw the love in them. It only reaffirmed the sense of fulfillment inside us. It told us that what we had shared was pure, and we would share it again.I placed my head on her shoulder, breathing in her womanly perfume as it wafted in from her hair,. They just always kept two or three in their purses. That was the extent of it. They knew women had babies, but had no idea of how it was accomplished; dittoe on diseases.

Right up until bedtime I thought I was getting away with it, but when I was undressed and ready to get into bed David ordered me to lie across it and ready myself for a spanking.When he said 'spanking' and started tying my cuffs to the bed leg, I thought that I would be getting another tanning like the one I had when Sandra and John were there.

Every time I came, more of my pussy juices oozed out and mixed with the loads of jizz, giving me more to suck down and making the cum smoothie sweeter with every orgasm. I sucked on the straw non-stop until every last drop of hot cum had been pulled from my cunt. Sara moved the end of the tube around inside my pussy, making sure I got all I could, and then pulled it out and licked and sucked my pussy walls clean.I held the last big gulp of cum in my mouth and swished it around as Sara pulled.
