My parents are both going out for the night, and I'll finally be able to finish what I started.
I have been hard as a rock and dripping precum since my little sister had been interrupted while sucking and jerking my cock earlier today. Damn that was frustrating when my mom came home, just as I was about to cum in her mouth. I suppose I could have jerked off and released my load before now, but I wanted to wait till tonight to have her swallow my cum, when my parents would be gone for the entire evening.
Shit, I just realized that I'll be called down to supper in a few minutes and I can't very well show up with a massive boner. Just as I was about ready to jerk off, my little sister came running in and said Mom said to tell you dinner will be ready in ten minutes. She looked at the bulge in my pants and started walking towards me. I asked her what she was doing and she said she ought to finish what she had started earlier. I told her that there wasn't enough time but she ignored me and got on her knees in front of me, and pulled my pants and underwear down. My cock sprang out covered in precum and bobbed in front of her mouth.
She hadn't even closed my bedroom door and I didn't notice until Dad walked in and asked us what we were doing. With my pants down, my sister on her knees, and my hard cock sticking straight out, there wasn't any lie I could come up with that would have got me out of this jam. My little sister got up and ran out of my room, as I furiously pulled up my pants and sat down on my bed.
As I waited for the shit storm to erupt, I happened to notice that my father's pants were bulging and he appeared to have a huge erection. He saw me glancing down and moved quickly to hide it by sitting on my bed.
He finally spoke and asked me what had been going on with my little sister. I had no words to try and explain, so I just sat there mute. His face was red and I thought he might be getting ready to blow up and hit me. Instead, he put his arm around my shoulder and told me that he understood. He said that when he was a horny teen, he had fooled around with his little sister and found it pretty satisfying.He went on to describe how his little sister would come to his room after school and suck his cock until he ejaculated in her mouth. Best blowjobs I ever had, he said, and then got up and left my room.
I sat dumbstruck not knowing what to hell to make of his conversation. Did he just give me permission? I heard Mom yelling that dinner was served, and since my boner was long gone, I headed downstairs.
My chair was right beside my sisters, and just looking at her, my cock got fully hard again. My dad was at the end of the table and mom was still getting food ready to serve in the kitchen. My dad smiled at me slyly and got up to pull his chair closer to the table. Holy shit, he had an erection sticking straight out, and next thing I know my sister is telling me to look at Dad's cock. Dad just smiled and told her to check her brother's pants. She reached over and massaged my erection through my pants. She said to my dad that my cock was hard too. She then asked my father if he wanted her to suck on his cock like she had done with me. When he said sure, she got up and crawled under the table and the next thing I heard was his zipper being pulled down, followed by slurping sounds and then a low moan from him.
My mom came in carrying the platters and asked where my sister was. Dad told her that she had dropped her fork and was under the table looking for it. My sister's head surfaced and I handed her a fork to get up and sit down with.
Mom said well, let's eat everyone, I'm starved.
After we finished eating, my dad told me that he would not be going out tonight, but mom was still going. It occurred to me that he wanted more from my sister and must have told a story to mom about why he couldn't go.
We cleaned up after dinner and I headed to my room, while dad had my sister sitting in his lap in the living room. Mom was upstairs getting ready to go out, so I glanced back down to the living room and realized that he had his cock out and was having my sister jerk it. Soon she was on her knees sucking his cock, and when I saw his hand grab her head and push down, I figured he was about to cum in her mouth.
Sure enough, he thrust upwards and my sister gasped as cum flew out the corners of her mouth and dribbled down his cock. When he released her head, she stood up and asked dad how she did. He told her it was great, but she'd have to practice a lot, so she could swallow everything.
I was not only shocked, but also horny as hell. My cock was throbbing and needed a release badly. I went to my room, closed the door and dropped my pants and started jerking off furiously. As my cum began flying out of my cock, the door opened and my mother stood watching, red faced and in shock.
When she finally spoke, she said that I should get a towel and clean up. She turned and left as I stood there not knowing what the hell to do next. I sat on my bed and wished to hell that this day had never happened. My father is a pervert and now my mom thinks I am one too. I laid back on my bed and wondered what I should do or say to get myself out of this mess.
Later that evening when my mother was out, my dad came to my room and asked if I was ready to have some fun. I didn't know what to say, so I just stared at him, until he said that he wanted to watch me get sucked off by my sister. I kind of nodded, not knowing what to say, and he left my room. A minute later, he came back with my sister and told her he wanted to watch her suck my cock. I couldn't even get hard with him standing there waiting, so I just sat on my bed, and looked at the floor. I guess he got annoyed, because he told my sister to suck him instead. I looked up to see my sister on her knees, bobbing her head up and down on his cock, with him holding her head tightly, trying to get deeper in her mouth. He groaned and held her head tight as his cum filled my sister's mouth. It was obvious that she was doing her best to swallow, but some shot out the corners of her mouth and dribbled down his cock.
I was now hard as a rock, and stood up to get some myself, but my father told me to stop and wait for him to join in. I wasn't sure what he meant, until he placed my sister in his lap, and tried to get his cock into her bum. She resisted, but he pushed hard and eventually got his cockhead into her tight opening. He told her to start sucking me while he bounced her up and down on his cock. As I inserted my cock into her mouth, my father pulled down hard, impaling her bum fully on his cock. She screamed and almost bit my cock from the shock and pain. He told her to start sucking, so she took almost all of my cock into her mouth and began bobbing up and down. When I unloaded in her mouth, Dad talked to her encouraging her to swallow every drop and she did. My father soon followed with his own orgasm, filling her ass with his load.
We all took a breath and while relaxing, the door flew open and my mother walked in and said "so this is what you do while I'm out".
