My Sister Kelly Pt. 4

I got off my shift at the hospital and instead of running some errands like I told Eric I would, I decided to come home and change out of my scrubs and then go out. I got home and the house was pretty quiet, I could tell my daughter Kelly was out. I quietly went upstairs to see if my son Eric was home. It was apparent he was not expecting me home because his bedroom door was wide open. I heard some talking and what sounded like some moaning coming from his room. I could have called out but my curiosity was peaked so I decided to sneak up to his doorway to see what he was doing. I looked in and saw my son sitting naked at his computer clearly jacking off to some porn he was looking at online. I watched my son with lust and fascination for a few minutes as he worked his cock, moaning and I could hear him saying his sister’s name so I knew he was fantasying about fucking her.

I was torn in half, part of me thought I was his mom and either saying something or just walking away and making some loud noise so he knew I was home. Then there was the other part of me, the very sexually aroused part. I hadn’t been with a man in over two years! I noticed that my lustful thoughts were deepened with the addition of incestuous thoughts added in. Suddenly I noticed that I had my hand down my scrubs, massaging my very wet pussy. I thought about having my son fuck me like I saw him fucking my daughter. I didn’t know if he would find me as sexually appealing. After all I wasn’t his 20 year old sister. I was his mom and an older woman. I knew it was wrong but I let my lust laden thoughts direct my next action.

I walked into my sons’ room, intent on breaking my drought on no sexual activity. My son was really into his lustful thoughts about his sister because he did not hear me come in. I put my hand on his shoulder and said, “So Eric, this is what you do when I am not home.” My son jumped, startled by having been caught by his mom. He quickly took his hand from off of his cock and grabbed his mouse with the intent to try and close the porno he was looking at. As he did this he said out loud, “Oh shit mom!” I grabbed his hand and stopped him. Our eyes met and smiled at him, “It’s ok. All guys do this. If it gives you pleasure you can do it, I don’t mind.” My son just looked at me, not knowing what to do or say. “Well Eric, you might as well get yourself off, I am sure you were close to cumming.” My son looked at me in shock, surprised to hear this coming from his own mother. “I can’t jack off with you watching me!” But as he said this I knew he was lying. He was just trying to play innocent. If he knew that I knew him and my daughter were fucking I am sure he would have responded differently. But then I thought maybe he didn’t find me that sexually appealing. But yet I thought I had so much more experience; I knew he would enjoy being fucked by an older woman. I could have said I knew about him and Kelly but I didn’t want to spoil that fun they were having and my fun of watching. “Ok…well how about I just get out of your sight and then you can finish getting off.” So without another word I dropped down onto my knees and crawled under his desk. “Mom! What the hell are you doing?” I called out from under his desk, “Just keep watching your nice porno video son.” I crawled to my sons legs, I put my hands on his knees and my son automatically spread his legs.

My sons cock looked so good up close. It was a nice length and width. I could see how wet it was, covered with his pre cum. I hadn’t tasted pre cum in so long but now I was going to get my taste of what my daughter seemed to love. I pulled my sons’ chair in and moved into his legs taking his cock into my mouth. Wow! His pre cum tasted so good! I knew instantly why my daughter loved sucking her brother’s cock so much. I slid his prick in and out of my mouth a couple of times, I heard my son moan. Then I said, “Are you watching your screen?” “Oh fuck yes mom!” “Good. Keep watching it Eric and just pretend I am that woman on the screen sucking your nice cock.” I began to bob my head up and down on my son’s cock. Eric put his hands under the desk and on to my head helping to move my head up and his pre cum covered cock. “Oooh yes…mom…fucking don’t stop! That’s it! Fuck yes! Suck my fucking cock!” “Eric…don’t think of me as your mom, just as that woman on your screen.” My son tried pushing his chair back but I wouldn’t let him, I guess I felt that if he didn’t actually see me with his cock in my mouth then it our incestuous action would be ok.

I listened to my son moaning as I sucked on his nice hard prick. He kept running his hands through my long black hair. “Yeah that’s it mom. Fucking suck my cock. Suck it mom, suck it good.” The fact my son was enjoying our encounter only added to my lust. I ran my lips down on side of my sons’ cock and then back up the other side then I ran my tongue all over Eric’s’ prick head. I lapped up the pre cum oozing out of his nice piss slit. Then I slid my sons’ cock back into my hot, wet mouth. Eric pushed his chair away from the desk trying to get me to come along with him. I got a good look at his throbbing, red, saliva covered cock as it bounced straight up into the air. “Mom, come out from under there, I wanna watch you suck on my cock.” “No Eric! I told you, watch the screen and just pretend that it is that woman sucking your cock.” “Fuck that mom! I want to watch you sucking my cock!” I got up under his desk, stood up and started to walk for his bedroom door. “Sorry Eric. I told you I wouldn’t give you a blow job if pulled away from the desk.” I looked at my son with a bewilder look on his face. Deep down I was hoping my son wouldn’t just let me leave. I truly wanted to suck his cock; I wanted to make my son cum in my mouth. I trusted my son’s lust was overflowing him, like mine was and I was not disappointed!

My son grabbed me by my arm and spun me around facing him. “Oh no you don’t mom! You are not going anywhere. You started to suck my cock and you are going to finish!” I never saw such lust in guys’ eyes before as I saw in my son’s. I went flush as I knew he had nothing but pure lustful thoughts in his mind. I didn’t say anything back to my son but I did try to pull loose, when I did my son pulled me right up against his naked body. His hard cock felt so good up against my body as I felt it through my scrubs. Then he took his other hand, moved it around my back, pulling me closer to him. Our eyes met and he kissed me with a deep kiss on my lips. As he did this his hand went down to my ass and he gave it a nice hard grab. This sent eclectic tingling up my spine. Then my son pulled me over to his dresser and took something out of it with his free hand.

“Eric, what are you going to do?” My son turned around to face me, “I’m going to make sure you finish sucking my cock mom!” He then pulled me over to his bed, “Get up on the bed mom!” I purposely refused; I knew my son was getting more excited with me being difficult. “Mom! Get up on the bed now!” I slowly sat down on my sons’ bed. “Sit up against the head board!” I slid myself back up against his headboard, still curious as to what my son was going to do. My son then produced his other hand from behind his back and I saw he had a couple of ties in his hand. Without a word my son very, very quickly tied my wrists up to his bed board. This was so kinky, I never had a man do this to me before and since it was my own son, it really drove my lust to a new level. However I did my best to hide my own lust but I figured my son could see my lust and glee in my eyes. My son stood up on the bed in front of me, he looked at me with such lust as he very slowly stroked his hard cock. “Now you can’t go anywhere mom.” He bent down, fixed the pillows behind me as he pulled me down. Then my son Eric straddled my body, still stroking his cock he knelt down in front of me. His cock and my mouth were at just the right height.

My son moved forward and tried to put his cock in my mouth but I kept my mouth shut and turned my head. As I did this I said, “No Eric. I am not going to suck your cock.” My son held his cock in his hand, smiled and slapped it against my cheek. I could feel his hot, sticky pre cum on my face. Then he ran his prick head across my closed lips, making sure he got pre cum on them. Then he pulled back to watch me instinctively lick his pre cum off of my lips. “Yeah that’s it mom. Swallow my pre cum. See, I knew you still wanted to suck my cock.” Then he just looked at me and smiled with this odd smile. “What are you looking at Eric?” I couldn’t help but keep looking at his prick. I really did want it in my mouth and I couldn’t wait much longer. “You are really a beautiful woman mom. You have such a beautiful face.” I blushed as my son said this to me. He touched my cheek gently, and then touched my chin. “Oh you are just saying that so I will give you a blow job.” “No mom, I am serious. Now if I want to get you to give me blow job, I will tell you how beautiful your lips are. That your lips would look even more beautiful wrapped around my cock.” At that point I just looked at my son, smiled, opened my mouth and stuck my tongue out. My son slid his cock right into my mouth.

Eric ran his hands through my hair and ended up leaving them behind my head. My son slowly, at first, fucked my mouth his hard prick. He just kept looking down at me as he slid his prick in and out of mouth. “Mmm, yeah mom. Your lips look so good wrapped around my cock. Do you like how my pre cum taste’s?” My son removed his prick from my mouth, “Yes sweet heart. You taste so good.” I opened my mouth again, my son told me to stick my tongue out. He slapped his prick on my tongue and milked some pre cum out on to it. Eric then told me to swallow it which I happily did. I opened my mouth again for my son’s cock. He slid it in and began to fuck my mouth faster than before. “Oh yeah mom! Your mouth feels so good. I’m gonna fucking fill your mouth with my cum. How does that sound mom? Do you want that? Do you want me to blow my load in your mouth?” All I could do was shake my head yes. I was really getting carried away with this whole situation with my son.
