It was a summer's evening, July i remember well :-P, i'm heading toward the lunch-room for the dinner, my sister is sitting at the table and she wears...a tunic for the house and i see her from behind and, given the backrest of the chair was at half, i can see from behind her, and i see her beautiful ass tight inside that tunic, i don't know what kind and what size of panties she had because the tunic was of dark color blue blue-night :-P but anyway her buttocks they sink for well on the chair. She commented, "that if it was up to her she would change that uniform for one of the new lines of Sheer gossamer negligee's which would show off the under wear all the time!"Wayne smiled and added it's certainly worth a thought or two. As John stepped back from Agatha, he suddenly bumped into Jean; instead of the expected torrent of abuse he expected instead he simply felt her hands slide around his waist and in a sudden movement his frilly panties were around his ankles and Agatha burst out. A lead was put on my testicles by the assistant who helped to ensure my erection remained at its best by stroking my penis very gently and grasping it firmly and the softly . .As for me all this was traumatic and at the same time exciting. She whispered " try not to cum as you'll be milked on the podium " I became even more randy at this piece of advice though very embarrassed that every woman in the hall would be watching with a horny eye at my performance . Doubts about my performance. “Get on that fucking bed and open those whore legs… and use your sopping pussy to muffle her screams” “Ross…”“Do it… do it mum… muffle her screams with that sopping pussy” I slapped Vicky’s ass harder made her yell even louder than before which prompted mum to jump on the bed and lay at Vicky’s head. She daren’t allow her husband to hear anything downstairs Cathy and I watched… both with big grins on our face as Mother slowly spread her legs wide, lifting Vicky’s head muttering she was sorry to.
