My sister 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.
She was already wearing her makeup and her eyes were smoky; sexy, and her lips were ruby-red. She licked her lips and contemplated the erection pushing at the front of my shorts.
Shelly pushed a finger into her pussy; the lycra tights would only allow it to enter a little, but god it looked so sexy. 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 gaining entry to a girl's treasures," Shelly eyed me, and both mom and I blushed a deep red.
Did Shelly know I had fucked mom in the car while she sat on my lap during the ride home?
"Shelly go and get changed; Mike, dinner is in the fridge just microwave it," she smiled at me.
"I'll be home about ten so if you are still awake we can share dessert," mom winked at me.
I looked across at Shelly and saw a knowing smirk on her face. Fuck! She must know what mom and I had been up to in the back of her car!
A horn hooted from outside and mom gave me a 'don't worry; nothing will happen' look and kissed me primly on the cheek and wiped away the lipstick she left there with her thumb. She smiled at Shelly.
"Have a good time Shelly; see you both later," she walked over to the front door, her magnificent ass waggling in her tight skirt.
Shelly stuck out her tongue at me and got up from the couch and went upstairs to change.
I raced upstairs with my raging hardon and locked myself in the bathroom. I freed my erection from my shorts and bought a pair of mom's soiled panties to my face; I wrapped my cock in a pair of Shelley's panties and frantically masturbated. I filled my sister's panties with creamy sperm in about thirty seconds and cleaned up the mess; burying the soiled panties at the bottom of the laundry basket.
I went to my room and surfed the net for about an hour or so, trying not to look too often at the time. Ten o'clock couldn't come around fast enough. I wanted to fuck my mother again!
I went down stairs about an hour later to get my dinner and was surprised to see that my sister was still here. She was lounging on the couch again, in the same position as before. I was wearing a pair of shorts and was barefoot and shirt-less. I took her in. Her bottle-blonde hair had been teased out and framed her pretty face which was heavily made up; black mascara and eyeliner, mauve eyeshadow, rouged cheeks and ruby-red lipstick glistened her lips. She was wearing a blue mini-dress, the long sleeves and shoulders were made of semi-transparent black nylon material; the dress itself was a blue spandex blend and clung to her body like a glove.
The hem rested at the top of her thighs; her legs were swathed in expensive 15 denier flesh-toned pantyhose and they glistened in the dull lamplight. Her feet were shod in four-inch black patent leather 'fuck-me' pumps. She looked hot and my cock began to engorge, seeing her dressed that way sprawled on the couch, legs akimbo.
