Mommy Sits on my Lap part 3

My s****r Shelly sprawled on the couch, one leg hanging over the armrest the other on lay out straight along the couch. She was wearing her favourite Venosan Ultima Lycra-Nylon Leggings. The sheer fabric moulded to her cunt and it was obvious she wasn't wearing panties underneath. Her feet were bare and she wore a loose fitting vest, which was slack enough for me to see her satin bra through the armhole. My cock was hard and despite my best efforts I couldn't take my eyes off her. We were both pretending to watch TV but we were very aware of each other. Her perfume wafted across the room. I could hear mom rummaging around in the kitchen. "So is this view as good as the view I gave you down at the gazebo last night?" she smiled. She slid a red painted fingernail along the juncture of her thighs and gently rubbed the pad of her finger along the seam of her tights. I blushed and said nothing. "Which did you enjoy more; watching me fuck that boy or watching me rub my cunt for you?" she grinned and rubbed her silken-shrouded mound, just like she had last night. "Jesus Shelly, shut the fuck up will ya!" I hissed. She just smirked and opened her legs wider and began to rub her pussy through the diaphanous fabric. "I'm going out with Tim tonight, but a quick rub before I go isn't going to hurt," she stared at me with her hazel eyes.

I stroked my cock through my shorts and Shelly grinned. "Mom!" she shouted, and I quickly took my hand from my cock. Shelly smirked at me. "Yes Hon?" mom replied from the kitchen, then I heard the click-clack of her heels. Mom was wearing a two piece suit, jewellery and makeup; she too was going out, and I was jealous. We had fucked most of the night away and I wanted to fuck her again tonight but mom said she had to go out as she had already made the date. She didn't want either of us behaving differently now that we were lovers; she didn't want to raise anyone's suspicions. Mom stood beside me and I wondered if she did it on purpose. Her skirt was very short and I could just see the dark band of her control-top pantyhose. I sneaked a finger out and stroked her leg but mom pushed it away and gave me a scowl. Even though Shelly couldn't see me do it I knew it was dangerous. "What's up Shelly?" mom asked. "Nothing really, just wondered if you wanted Tim and I to give you a lift?" "No Hon, Steve is picking me up in his car," she replied and I felt a pang of jealousy. "You better get ready Shelly; Tim will be here soon and you can't go out dressed like that," she admonished. "I bet Tim would like it though; make it easier for him to get at me," Shelly goaded my mother. "Apparently some boys find that pantyhose are no encumbrance to ...
