When I let go I slid my head down to the seven inch mark more easily, but still couldn't get that eighth inch. I started sliding my mouth faster and ...aster. I would open my mouth on the way down and close it on the way up. When I was sure there was a good amount of slippery spit on the head, I got up from the bed and positioned the dildo on the edge of the bed. I turned around, pulled my thong to the side and lifed my skirt up. The feeling of the thick head resting between my ass cheeks. Balmy weather had always made her feel sexy... and they would have the house to themselves. No more spying, none of Mom's controlling.Mom had become so damned paranoid... and suspicious. Linda recalled the quarrel between Mom and herself over the bedroom keys. Mom wanted to prevent them from locking the doors. Fortunately Dad had settled the matter. Drawing his wife aside he had whispered a few words into her ear."But Fred..." Mom protested.There were more whispered words until Mom's face. We went for the general topic for talking and suddenly the topic changed to sex and I said to her that I don’t know anything about it and it is a sin to know in this age.She said it is not like that but you should not divert the mind and think about that then she explained about the various types in the sex which could be enjoyed without boring up to lifetime. I could not understand certain things which I asked her.She asked do you need in practical explanation, suddenly I said yes and she held. She spread her legs wide for him to fit comfortably in her pelvic saddle and they rocked their way down the highway of sin into a lazy fog-shrouded state of constant tingles just waiting for that key element that would push them both over the edge of total release.It was Linda that surrendered first to the basic instinct that was restrained inside her beautiful body. She quickly went from a rhythmic panting exposing her sordid depravity to a series of animal like grunts similar to the noises.
