Chapter Two
When I came in, my sister was drinking a glass of tea and talking with mom. She was wearing a tank top that exposed her pierced navel, surrounded by it's star tattoo. It did nothing to hide the fact she was braless. She also had on a pair of spandex shorts that formed a camel toe between her slightly spread legs. My penis began to stir within my shorts, as I grabbed a can of Mountain Dew from the fridge.
"Hi, Sis." I said, popping the can open.
Mom was happily wiping down the table, as her bare titties jiggled within the thin housedress she was wearing, the hemline riding up her bare butt as well. "How'd you like to go spend the weekend with Sis?" Mom asked me, rising up. I saw her nipples, surrounded by its dark areolas standing out from her breasts.
"It'll be cool, Mom." I said, as I looked over to Sis. She winked at me, and slid her hand over her camel toe. I saw a tiny dark spot, as her pussy was beginning to drip with anticipation. My penis had aroused within my shorts, as I turned and went to my room to pack.
We left in Sis's convertible in the late evening and rode to Arby's for supper. "Mom sure was happy to get me away." I commented.
"Yes, I think her boyfriend's coming over for a while." said Sis, as we went into the restaurant. I watched her spandex clad butt sway as she headed to the counter to place our orders. The teen guy must've noticed that Sis didn't have a bra on, and became flustered as he took the order. I smiled at his reaction as we retrieved our sodas.
We ate as I admired Sis's nipples showing through her top. "I have an idea," Sis smiled. "Let's stop at Wal-Mart and get us a black t-shirt, then go back home and see if we can catch mom with her boyfriend." My penis popped up at the dariness of her idea spying on mom.
Soon we were on our way back home in the darkness with the t-shirts, parked the car on the farm road next to the driveway, and pulled our other shirts off. I saw Sis's titties momentarily as she pulled her shirt over her head, and I quickly did mine are as well. We walked up the drive in silence toward the lights, and crept softly around the house to the den windows, which were at ground level, and settled ourselves between the shrubberies.
We saw mom's boyfriend sitting on the sofa with a can of beer in his hand and wearing his boxers. Mom came into the room with a bag of chips and a bowl of dip. She had on a sheer negligee that showed her titties, and no panties, as she came to the sofa. They sat there for a while eating and drinking. My penis was swollen in it's excitement, and I had to reach into my shorts to shift it into a more comfortable position.
I glanced at Sis, and she had her hand inside her tight shorts as well, working her finger in her pussy. I looked back as the guy set his can on the table, and reached around mom, as she leaned over to kiss him. He began to remove her negligee, as she appeared to be laughing, and stood before him naked. Mom freed the guy's penis from his boxers, and straddled his legs as she lowered herself onto it.
The guy had one hand on Mom's butt and his other hand on his penis, guiding it into her pussy until she settled onto his lap. Mom leaned forward and kissed him, before she began to bounce on his lap, as he reached up and grasped her bobbing titties. I looked over to Sis, and she was working her fingers vigorously within her spandex, as my penis throbbed and oozed its precum.
Mom raised herself off his penis, and we saw it was coated with his cum and her juice, as well as dripping out of mom's pussy. She stood before the guy, and he began to lick her pussy clean. A few moments later she got down on her knees before him and started sucking on his penis, her butt was exposed towards the window, spread for us to see. A little cum was still oozing from her reddened, shaved pussy.
Sis withdrew her hand from her shorts with a sigh, and motioned for me to come. We crept away from the window, and began to walk back to the car. I was walking uncomfortably with my swollen penis, and reached inside my shorts to shift it again into a more comfortable position. Sis noticed. "Oh, we have to do something about that."
We stopped in the middle of the driveway, and Sis pulled my shorts down. She took my hard penis into her mouth and began to suck as I reached down to her head and held her hair. In no time, my hot cum was shooting into her mouth as I sighed with exhilaration, as images of my mom's dripping pussy played back through my mind. As my penis relaxed, I stepped out of my shorts and Sis picked them up.
We got into the car, I noticed a large dark spot on the crotch of Sis's shorts where it was obvious she had came too. Before Sis sat in the seat, she pulled her shorts off. Sis and I rode along in silence, as I clutched my semi flaccid penis, and she occasionally massaged her pussy. Little did people in other cars around us knew we were bottomless, even at traffic lights.
It was pretty late as we pulled into a convenience store for gas. As Sis pumped, she tossed me her purse and had me to go pay. Upon entering, I noticed the same girl working that had seen Sis and I the last time we stopped. I was conscious that I didn't have shorts on, but the shirt was long enough to just cover my butt, however my penis was erecting, and becoming noticeable. The girl smiled in recognition as I gave her the money.
Sis came in, and went to the bathroom, and I followed her. We both peed in our respective urinals in the unisex room. As Sis stood, I had to feel her nudity again, as it was a while since the last time I touched her bare butt. She came around to me as I knelt on the floor and spreaded her pussy. I pushed my tongue inside and began to lick her engorged clit when the door opened. The girl stood there watching as Sis began to cum into my mouth.
