Bob had gone out to the liquor store to pick up provisions for the party they had planned for that evening, and she looked anxiously up the block for ... sign of the station wagon returning to the house.Weekends had been a joy to both of them since they had returned from North Carolina at the end of July, and the reasons for this were still somewhat perplexing to her. By all rights, she thought as she resumed her dusting, what had transpired in that sordid little country shack should have given. Kissing my way back up his smooth shaft I could feel it twitching until I sank my mouth back around it again. He was back inside me and he was trying to fuck my mouth“Mom, Mom”He give one almighty thrust in to my mouth, arching his back and came. The power of his seed hit the back of my throat and I had to swallow fast as his cock twitched and jumped in my mouth again.Squirt after squirt filled my mouth and I was loosing the battle to swallow it all in time, I tried sucking what was leaking. She was enjoying it. He grabbed her ass and then she removed his hand suddenly, i was relieved that she is protesting finally. Then to my surprise, she pointed her ass towards him a bit, this was the signal. He grabbed her from her hips and started humping her from over the leggings. His hard dick might have poked and excited my slutty sister. Her one hand was on the pole given to take support. Her grip was so tight on the pole that i understood that she is enjoying this insanity. They both. When she reached the red satin pair I'd left, I saw her stop dead and shake her head as she took them off the line and drop them into the laundry basket. She stood for a minute then suddenly looked round as if she knew she was being watched. Luckily I managed to step back so she didn't see that it was me that was the watcher. After placing the rest of the laundry in the basket, she looked round the garden again then, still shaking her head, went back indoors. This went on for a couple of weeks.
