With my ass in the air prelubed I watched the porn while preparing a larger black dildo, 7" around. I first sicked it attempting to deep throat all 8 ...nches but could only manage 4" before gagging. I kept going and got anout 5 in, by that point the fake dick was well lubed and my cock ached from my intense 6 inch erection.Slowly i rubbed the huge bulbous head over my waiting anxious fuck hole and pushed. The head being 5" around and working its way up to 7 in popped in without too much. "Your hopeless," she smile, shaking her head. "Now lets get the dinner made. People who do as much fucking as we do, need our sustenance." "I wouldn't want to make a mess on your dress," I said, "but I won't be able to relax and eat with this hard-on." "That's O.K.," she replied. "I'll put on a show for you, while you jerk off." I lay down on the bed and grasped my dick firmly with my right hand. As I began to masturbate, Vanessa started dancing for me, lifting her dress slowly to show me some. I always wanted to fuck her at least once, and that night, I got my opportunity.We were going to head into the bathroom and close the door, but, after a long discussion, agreed that we could easier hear someone coming down the stairs, hear the stairs creak, or hear footsteps, so, without warning, Kristina just simply started undressing, and it began. We were halfway through the foreplay when, much to our shock and surprise, my step-daughter was discovered standing in the hallway on the bottom. She knew that wasnt my hand and turned to me and looked down at my now hard cock. Oh my she said. She looked abit worried, james i dont think we should be doing this she said. Dam i was thinking to myself, did she want me to stop, had it gone to far i thought. Sorry ill stop i said again but just before i did i slapped her ass again with the tip of my dick. Oh but that fills nice she said facing forwards. Like this i replied and let go off my cock and rested it between her ass cheeks. mmm yes.
