I rolled Mark towards me so he would not tent the blankets as I lay on my back. Ellie emerged from the shower a few minutes later and Dan entered. Ell...e had on a baby doll outfit that hid nothing. Her full breasts, pointed nipples and mound were on full display through the thin fabric. She settled down on the home-made bed waiting for Dan.Mark unintentionally moaned softly in my ear to which I whispered softly, "Don't be greedy; if anything happens we are going to share her," the expression on. Then I headed out to the pool to read the paper in the shade by our picnic table.In an hour or so, Lee came out to join me. A wave from inside the patio door and a cheery, "Bye, Dad, bye, Mom" meant Julie was out the door, off to somewhere, I was pretty sure I could guess where.I looked at my spouse."Well?" Well."I waited. Lee took a swig of what had to be pretty cold coffee by now and made a face."She's fine."I didn't realize I'd been holding my breath until I heard myself expel a lungful or. He could feel himself penetrating her deeply. She leaned down over him and threw her hips up and down, and he decided he would help, too. He was able to work very far into her, keeping a steady rhythm. For the second time that night he felt himself nearing orgasm. As she panted over him he breathed, "I'm gonna cum!" "It's ok, I've had my..." she was breathing so heavily he almost couldn't make out what she was saying, "I've had my shot." He began to pump harder and harder, plunging in and. In her fantasy he did. His hand came down hard on her ass making a slapping sound so loud that it hurt Sara’s ears. She said it again, louder this time. Again, he hit her, and again. She begged out loud for it now. She saw herself being spanked, felt the big, hard cock of her Master pounding in and out of her slutty cunt and she came. Sara came like never before. She lost control of herself and was flopping around on her bed. She twitched like that for several seconds before calming.
