?You can stay. But if you do, it will be right there, on your knees.?Dan’s voice startled me out of my thoughts. Did I want to stay? Oh god, yes! Bu... what did that mean – on my knees? Why would he want me to?oh. I dropped to my knees. I still don’t know why I did it but I did. I wanted to see him fuck that girl, I wanted to hear her moan and plead while he did. Somehow I wanted to be part of it. And so I just sank down on the carpet, eyes glued to his hands that were still caressing her ass.. Nor was it an aggressive act. Neither sat at an end with the other encroaching on her space. They sat as a couple in the middle of the sofa. I thought I detected more than a friendship between the two."I've a confession," Kelly said."It was my fault," Rita broke in."We have a confession then," Kelly corrected."I ran an experiment on you without your permission," Rita jumped in."Rita explained to me what she had in mind and I jumped at the chance to help her," Kelly added. "But I have to say. I kept squeezing my ass after each of his pulses… my muscles milking his cock. I wanted every drop and to give him as much or more pleasure than any ass had ever given him before. I held him tight in my ass, savoring the heat of his meat and the feeling of his cum working it's way deeper into my hungry ass. With a sigh and a wet splooop his shrinking cock popped out of my clutching asshole.I looked back down between my widely spread thighs to see some of his thick cum gush out of my gaping. "Don't do that, let it cry. It'll wash it out," Dad said softly as he stepped to my side. "Lets have a look." I tipped my head up, smelling his beer and fag breath as he gazed intently into my right eye widening the lids with his stubby yet sensitive fingers. "There's nothing in there anyway, let me wipe the tears away."Sitting beside me, he dabbed at my eye with a tissue he'd produced from his jeans pocket. I couldn't vouch for the cleanliness of it, but his tender thoughts and deeds.
