It was an "as is" final sale. I couldn't take it back if I wanted... especially not without explaining what was really on the tape.She smiled and said... "Good, then we can watch it as much as we want." With that she was gone, leaving me as perplexed as I had been last night.I went to work in a mental fog. I rang up people's grocery orders wrong, didn't hear questions customers asked, and generally screwed up everything I touched. I even made a wrong turn on the expressway on the way home after. Mom was all wet at that time couldn’t understand what was happening to her. Mom was in a confusion as it bedroom was all dark.Initially thought it was the dad first and immediately recognized that was me. She caught hold of my hand pulled it off. I was stunned and before I recalled my mom has woken and caught me already. Shit, I was very afraid and immediately ran to my bed slept with by covering the whole body with a blanket. I thought this is the end of my life she will tell my dad definitely. ..Please do it to me.... Take it.... Take me now.... Fuck me hard!" He obviously had other plans. His mouth slowly explored the contours of her back, blazing a trail of hot kisses on his way down to the bottom of her spine. Getting on his knees, he pulled her down by the waist, and then reached around to her aching tits. He kneaded them firmly, taking each stiff nipple between his fingers, deftly rolling and pinching it. Raking his finger tips along her flanks, he grasped her butt, spreading. I was in a state of utter confusion when out of nowhere I felt a hard hit to my head and that was all I remember. When I awoke I was tied to a chair there was a window in front of me and what I saw made my heart sink to the bottom of my stomach. My girlfriend was laying nude with her face buried in my step-mom’s crouch munching away and looking like she loved it. Then after she clearly came allover my Gf’s face she looked at me and waved. Then she told my gf to stand up and put her hands.
