A Descent into Obsession

In the first part of this story my mom started taking some medication for her depression that turned her into a sex starved slut. The pills helped her with her depression but the side effect continued after my dad went on a business trip and my mom and I had been fucking our brains out for about a week. When she went back to the doctor for her weekly checkup, the doctor took her off the medication.

My dad came home a couple of days later and was disappointed to see my mom depressed again
.
“What happened with the medication?” He asked her

“The doctor took me off it for some reason.” She lied

At this point my dad and mom went into the bedroom so I couldn’t hear what they were saying but I could still hear some loud muffled voices and I knew my dad was mad about something. My guess is that he was getting the same kind of sex from my mom before he left as I was getting while he was gone and he wanted more of the sex. After a few minutes the talking stopped and I didn’t see either one of them till the next morning
.
“Where are you two going.” I asked when I saw them heading to the car the next morning
.
“Just to the doctors office. We’ll be back in an hour or so.” My dad said.

About three hours later they returned and I asked how things went and if there was anything wrong with either of them.

“No, No son we just had to get your mom’s medication straightened out.” my dad said with a big smile “Things should be back to normal in a few days.”

He was right too cuz within a day or so my mom was smiling again and my dad was happy as could be. I could hear them fucking like crazy at night cuz mom would always want to go to bed early and my dad was more than happy to join her.

It was still summer vacation so I decided to see if the medication had gotten my mom back to the sex starved slut that she was when she first started taking it. About an hour after my dad left for work I saw my mom in the kitchen wiping off the kitchen table. I came up behind her and grabbed her ass and said “Hi sexy”. She stood up and turned around with a surprised look on her face
.
“Scotty please don’t do that. What happened before can’t happen again. The dose of medication the doctor had me on before was to strong and that’s why I had those episodes. I’m much better now and that type of thing is just for your father and me.

“I don’t think so.” I said as I took her by the hand and led her into my bedroom.

“Scotty what are you doing?” she asked

“I just want to show you something and then you can decide for yourself what you want to do.” I told her as I put a DVD into the player in my room. It took only a second for the TV to come on and few seconds later a movie of my mom and me fucking like crazy came up on the TV screen. The video was bad enough with my mom sitting on my cock, sucking my dick and rubbing her pussy in my face but the audio left no question that my mom was the one that was in control and I was being used as a sex toy.

“Oh my God” she said “ What are you going to do with this video? Your dad won’t understand and if it ever got out my life would be ruined. You’re under age and I could go to jail.” She said as she moved over to the DVD player and ejected the disk. She took it out and broke it in half saying “That solves that.”

“I have plenty of copies.” I said “ You can break another one if it makes you feel any better.”

I moved over to her and put my hands on her shoulders. I pushed her down to her knees and pulled down my pants so my cock was right in front of her face. She looked up at me with tears running down her face as I took the back of her head and forced my cock into her mouth. She started to suck and stroke it as my cock started to grow in her mouth.

“That’s it mommy, suck your baby boys cock.” I said as I started moving my hips. “You said that you liked my cock in the movie. Do you like my cock mommy?” I asked as I continued fucking her face. I grabbed her by the hair, pulled her mouth of my cock and kissed her hard on the mouth. “Now strip off those clothes and ride this cock like I know you want to.” I said as I sat on the bed. She stood up and started to take off her clothes when I stopped her.

“No!!!” I said “ I want you to strip for me, not just take off your clothes.” I reached over, turned on the radio and watched as my mother started to strip to the music. She was still crying but she was moving her hips to the music and taking her clothes off like she was a pole dancer. This seemed to turn her on cuz when she was naked she crawled onto the bed and started sucking me off like it was her last meal. I grabbed her by the hair again and pulled her up so I could suck on her massive tits. She started to moan and put one hand behind my head to keep me sucking and with the other one she guided my cock into her pussy. With one thrust I was buried inside her and she let out a scream.

“Oh Scotty your so fucking big.” She said as she began pumping her hips. I laid back on the bed and watched as my mom began humping like crazy. “Once I get her going, the medication must kick in” I thought as she seemed to be getting more and more into the sex.

“Tell me what you want mommy?” I said

“I want to get fucked baby. I want your big cock to fuck me hard.” She said as she pounded down on my cock and started squeezing her own tits and pinching the nipples
.
“What else do you want mommy?” I asked

“I want you to cum inside me. I want to feel your cum in me.” She said as she had her first orgasm and her juices started to squirt all over my dick. I flipped her over on her back and started pounding into her as I lifted her legs and put them on my shoulders. At that moment, a thought came into my mind and I pulled my cock out and told her to stay where she was. I went into the bathroom and returned with a jar of Vaseline.

“What are you going to do with that?” My mom asked

“You’ll see” I said as I smeared a glob of it on my cock. I flipped her over onto her stomach and positioned my cock so I could push it in her ass.

“No baby don’t” she said “I’ve never”

“Shut up and take it like the slut you are” I said as I pushed the head of my dick into the bud of her ass. It took a little force to stick the head in but as I slowly pumped my cock into her the rest slid in nicely.

“Oh God it hurts” she said as I pumped more and more of my cock into her, well lubed ass. Her complaints turned into a low moaning by the time I was completely buried in her ass and was pumping her hard.

“Do you want me to stop mommy?” I asked

“No baby, fuck mommy’s ass. Cum in mommy’s ass like a good boy.” She said as her moans got louder and louder. She reached between her legs and started to rub her clit as I pumped my cock into her ass and she came hard soaking her hand and arm with her cum. She was so tight and the Vaseline worked so well that I soon came deep in her rectum and when I pulled out I could see streams of my cum leaking out of her ass hole.

I collapsed on the bed next to my mom and just lay there with my eyes closed for a few minutes. When I opened them my mom was sucking the cum off of my dick and gently rubbing my balls. She looked up at me and said “From now on, mommy’s ass is yours baby.” and went back to stroking and sucking my cock
.
We fucked once more that day and almost every day since then. When I went back to school we would have sex on the weekends my dad was away and during the week whenever we could get away with it. This went on till the drug trial was over with and mom’s libido came back to normal. That was two years ago and I’m now in college. My dad never found out and from what my mom told me, he was pretty happy with the situation while it lasted cuz he was getting plenty of sex also. I don’t know how they are getting along now but I have a girlfriend and am getting it on a regular basis so my mom is just a pleasant memory.
