Before I could turn around or make a move, I felt a whisper against my cheek, and a voice in my ear."I saw you and Katie having sex last night."I had ...o idea how to respond to that. I had no idea what to say. I had no idea what was going on my step-daughter's head. And I felt like a complete utter fool to have put myself in that position, doing something I knew I never should have done.I glanced at Katie on the couch, who obviously had not heard what my step-daughter said. I turned, and glanced. Then she took off her pants and as she did she turned around i got a glimpse of her ass with a matching thong of her bra style. FUCKING AMAZING. How could anyone want to divorce a woman like this??Then she took off her bra and her thongs and turned around and I thought I was going to have a heart attack. She only stood about 5'2". Her pussy was lighty shaven and her labia minora was just dangling. She smelled really nice too. I have no idea what she was wearing.Then I firmly told her to. Running my thumb over her hardening nipple, I lean forward and run my tongue up her cleavage and then nuzzle and kiss her soft neck."No, I have a better idea. First I'm going to get undressed and take you to bed and see just how wonderful an orgasm I can give you! We have an hour before your k**s come home from school, and that's going to be for you and me! And this time I'm going to take my time and fuck you thoroughly, so you can feel me coming inside you as well!"I smile at her staring. My cock began to rise, and she slid to her knees and took my member into her mouth. She could only take half before the gag caught her, but she was so tender and soft with the way she sucked and licked me from my balls to my mushroom head. I let her know that my orgasm was nearing, to allow her the time to pull away, but she continued her assault. Taking as much of my length as she could. Finally, I moaned and pulled her head to a stop midway on my cock and began to unload months of pent up.
