I was newly married for the second time and my wife had three children that i inherited so to speak. Twin boys who where paternal not identical, and a...daughter who was the youngest. We all got a long great. The boys and i were cool and my step daughter Haley were continuing to get along. She was protective of her dad, who was no longer in the picture due to his cheating. Haley would say little barbs about her dad this and her dad that. The funny part is that she was also very very demonstrative. .Occasionally I was asked to work extra hours on a Sunday or on a Friday night after school.On one such Friday night I had gone straight to the shop after school and was working in the back pricing up some new stock etc.There was only me, 16 at the time, and the elder brother (Mr R) present at the time.After a while I was asked to stock up some shelves at the front of the store and did as asked. It was during this time that I sensed myself being watched. I was pricing up some tins and stuff,. He rests there for a few seconds before pulling himself out and turning Tina over to kiss her passionately."You don't have any idea how long I've wanted to fuck you. I should have told you yesterday, after our first session." He whispers in her ear. "I've wanted to fuck you for so long to." She kisses him firmly.They go into the bathroom together to clean up and begin kissing passionately once more. They can't get enough of each other.As she leans over the bath, washing her pussy, he goes. .," remarked Myrna, still absorbing what had happened.Just then, they heard the sound of the front door to the apartment closing."Shit!" breathed Myrna. "My mom's home!"The two teenagers quickly stood up. Myrna pulled her bra back down over her breasts. Pulling her cum spattered blouse back down, she could see the wet spots on it, but realized there was nothing to be done about it now. Dylan was busily pulling up his pants as the colored girl wiped the semen off her glasses."Myrna?" called her.
