Jesus, she was freakin' me out! She spun on her heels and walked away, her hips swaying. Did her ass always look that good? She stopped and turned quickly. I was caught looking at my Mom's ass! Shiiiit! I looked up and her grin was slow and seductive, followed by a wink.
"Is there anything you want, sweetie?" she asked quietly.
"Nnnnnnooo, IIIII, dddon'ttt thththink sssssooo" I stammered.
"Ok, babe, maybe later" with another wink and she went out to the pool.
What the fuck was that?!? I fled to my room, my face on fire. I got dressed in a heartbeat and was gone from the house without seeing her again. I started over to Tim's, but I was afraid I was so freaked he'd notice and drag EVERYTHING out of me. I went downtown, instead. I saw some other buddies and hung out all day and part of the night.
I stayed out late enough that everybody was in bed, again. I walked down the hall and Mom and Dad's door was closed and latched. I took a shower and started out to the kitchen and noticed that the door was ajar like it was the other night. I stood staring at it, again transfixed. Was there a message, here? Did I not see the door correctly, earlier? Or was I reading something into nothing? Maybe they were done and Dad opened the door. Yeah, that must be it.
I went back into my room and got my dirty clothes. I walked to their door and hesitated, listening. I really didn't hear anything, so I figured they had gone to sleep while I was in the shower. In the back of my mind I was still hoping this was a silent invitation and my cock was more than happy to lead not only the thought process, but the way into their room. Well, Lil' Pete knows best.
I quietly pushed open their door. I was hoping to see a duplicate from the other night, but I did not. Instead Mom was on top of Dad in a reverse cowgirl, openly displaying her bouncing breasts to me. Once again, Dad couldn't see me because Mom's body was blocking his view of the door. Mom was really going at Dad's cock with her pussy. She was fiercely pounding down on him. I could hear these quiet grunts from her and Dad, every time she hit bottom. I stood and watched as my Mom fucked the living shit out of my Dad. His hands were on her hips encouraging her. Her eyes were closed and despite the fact that she was working hard, that look of contentment from the other night was there. My Mom obviously loved sex. My cock had returned to its pulsating hardness from before. Again, the head was peeking out from the waistband and I started thumbing it. I know I didn't make any noise, but Mom opened her eyes.
She looked me in the eyes and smiled a contented sensual smile and then her gaze drifted down my body to my cock. She flicked her eyes back to my eyes, back to my dick and then back to my eyes. I know my eyes widened and I pushed my shorts down and completely freed my throbbing member. It was as hot and hard as I had ever felt it, including any of the times with my sisters. I stood there with my cock jutting proudly from my body, not touching myself. My cock pulsed with every heartbeat. Mom licked her lips while gazing longingly at my engorged pole, while increasing the tempo of her hips on Dad. Even though I was at least ten feet away, I could smell her rising excitement. Her eyes started flickering between my eyes and my cock again. I drew my hand near and then dropped it away. I heard her moan, which triggered a moan from my father. He had no clue what was happening.
Her eyes returned to mine with a pleading look. I shook my head and she responded with another moan. I was so hard and so excited that pre-come was oozing out of the head of my cock. It dripped to the carpet and she moaned and licked her lips. I relented and squeezed the pre-come out and onto my fingers. I used it to lubricate my cock and started stroking. I dropped my eyes to her tits and then looked back up at her eyes. She kind of cocked her head to the side, not understanding what I wanted. I dropped my cock and she moaned again. The pleading look returned to her eyes. I reached up with my free hand and twirled my nipple. Understanding dawned on her face as she grabbed both her nipples and twisted savagely, moaning once again. I took my cock in my hand and was stroking it again. My hips started pumping in rhythm with her strokes to Dad's dick. I have no idea how long this took but as I watched her twisting and then trying to lick her own nipples I felt my cum rising in me. I stepped right to the end of the bed and her eyes got wide and fearful and she shook her head violently. I started cumming and made no attempt to catch the initial burst. By some miracle it did not land on Dad, but on one of her legs. Apparently that was enough to push her over the edge and her face contorted into one of bliss and agony and she groaned loudly that she was cumming. As I backed out of the room I saw her scoop the cum off her leg and into her mouth. I was still spurting and the sight of her eating my cum made the last spurt almost as violent as the first and it landed on the carpet.
I retreated to my bedroom and closed the door. I was drained. Again I had jerked off in front of my Mom, this time because she wanted it. I wondered where this might lead. As I drifted off to sleep, it was with visions of my Mom and my sisters, not dancing like sugarplums, but fucking each other and me like maniacs.
I awoke the next day still unsure of Mom's actions. Was she teasing me because she wanted more from me? Was she teasing me because Meghan had told her about Traci and me? Was I part of a fantasy that made her sex with dad, better? I had to get Traci alone and talk about this.
I got dressed and went out to the kitchen and Mom was not there. There was a note on the kitchen table that said she was going to the mall with Mrs. Anderson. She was taking Chris with her and they would be gone until dinner. She left instructions for preparations so she could get dinner ready as soon as she got home. She also said that Dad had gotten a call early and had an emergency at work that would keep him in Atlanta for 3 or 4 days. I looked in the garage and their cars were gone and I made a beeline for Traci's room. Her bed was empty and I heard the shower. I was naked in a heartbeat.
I went to the bathroom and quietly opened the door. Traci was in the shower with her back to me. I slipped into the shower as quietly as possible. I reached around her and cupped her tits and pulled her back to me, my blood engorged pole poking her ass. Traci screamed and jumped away.
"Peeeete, what the fuck are you doing?!?!" Traci hissed. "Mom is going to catch us!"
I smiled and pulled her back to me in a hug. I whispered in her ear "She and Chris are gone ALL day and we're alone." My sister hugged me tightly and then kissed me, shoving her tongue halfway down my throat.
"We can do things slowly, later" Traci hissed "But right now I need this." She turned and bent over and backed her beautiful ass up to my raging cock. "Fuck me, little brother, fuck me hard!"
I grabbed her hips and violently shoved my cock into her soaking pussy. I hit her cervix on the first thrust and she groaned. I stood there for a moment enjoying the feeling of her pussy. Traci squeezed my cock with her cunt muscles and moved forward. Her grip and small movement felt wonderful and it was obvious she wanted me to move with her. I withdrew and slammed back into her, stopping once again. She moaned and pushed back at me.
"Please, Pete, stop teasing me, I neeeed this, fuck me hard, NOW! I don't need tenderness, I NEED TO BE FUCKED!!!" Traci insisted.
You know, I'm smart enough that you only need to tell me things two or three times before I get it, so I did as my sister asked. I slammed my dick into her as she slammed back at me. Pretty soon we were wildly hammering each other. I could see her tits flying all over the place. Traci was grunting and moaning and was keeping up with our intense rhythm. As we fucked, I slid my hands up to grasp her tits. Her nipples were hot coals that were trying to burn holes in my hands. I squeezed and twirled them and felt Traci's juices gush between us. I slowed my thrusts and slid my right hand down to her pussy and found her clit. I rubbed it as hard as I could and Traci gasped.
"Peeete" she squealed "I'm cumming, I'm cumming" as she drenched us again.
I kept up my steady pace and the pressure on her clit as she shook and shimmied. I continued to pump into her as she came and then as she experienced the aftershocks of her orgasm. I still hadn't cum and hoped that I could make her cum again, before I did. As I continued to put pressure on her clit I slipped my left hand between us and pressed my thumb into her little butthole. My sister moaned again and pressed back into my hand. It was very awkward for me as I was all twisted around, but, Traci was enjoying it. Suddenly, she stepped forward off my dick and away from my hands. Then she scooted back against me again. My cock slid between her butt cheeks and rested there. Traci tipped her hips until the tip of my cock was barely touching her asshole. Then she backed up until I was penetrating her ass.
