A few minutes later my mother arrives to be greeted by the twins Hi Aunt Sue. They rushed to give her a hug. Then they began to help her make supper....After supper was over my parents retired to the Den to watch TV. The twins and I went down to the game room in the basement. We played a bit of pool and some video games. At 10:30 mother told us to go to bed. We took turns showering then went to bed. The Master bed room was between my bed room and the guest bedroom which took away all the chances. He expected to feel her cotton panties. Instead he found Pam, just Pam... no panties, just her firm, round, naked ass. He squeezed the flesh, his imagination filling in what his eyes could not at the moment see."Mm-m-m-m," Pam murmured.She pulled away from him slightly, leaning back against his arm and smiling as his hand squeezed and fondled the sweet cheek of her ass. Their crotches pressed even tighter. Her leg rubbed insistently against his hardening cock, brought his blood hotter.. This resulted in my being pegged as the master’s designated ass licker to which he put my mouth to extensive use. They thought it was very funny but I sincerely preferred crawling around in my hands and knees with my face in his ass as opposed to being alone with nothing.There were two very large parties. One was after the first week was complete and the other was the second to last night. They would invite several of their well off friends who contrasted us drastically. They were dressed. ." I bit my lip, my eyes getting heavy as I began to feel like I was adrift in a sea of pleasure."I have one too..." she smiled at me. I opened my eyes and her mouth was slightly open. She was watering. I imagined a wet place forming inside her panties underneath the black business skirt she wore. She was incredibly pretty and sexy. I have always thought so. I stay with her some weekends, a tradition that started when I was a little girl and mom was working a lot. Now I just go up to her.
