Introduction:

It would be helpful to you if you read part one first to understand the story.
The drive back from the hotel was both exhilarating and depressing at the same time. I had just had the greatest sexual experience of my life with my sister but I also knew it was the last. Now Celine had the tools she needed to regain her diminished sex life with her husband. Plus now I felt like I had nothing to look forward to. At least I had the memory of my gorgeous sister and that would have to do now.

It had been a couple of weeks since I had heard from my sister which was unusual and even my wife was starting to notice. “When’s the last time you spoke with your sister?” she asked. I mumbled that I didn’t really know and sulked away. I was now becoming fearful that my feelings for my sister were starting to affect my personal life and that I would have to address the issue sooner rather than later.

With great reservations I sent the following text to Celine. “Hey Sis, haven’t spoken to you in a while. I hope you are ok? Call me if you can. I miss you & I love you” I now knew something was up because anytime I ever sent a text to my sister, even when she was sick, I would always get a response right away. It had been three days, not good.

I was mopping at work, looking at photos of my sister on Facebook when the mailroom clerk dropped my daily load of mail on my desk. I skimmed each envelope until one got my attention. I recognized the hand writing and my heart skipped a beat. I frantically opened it up and warmth came over me as I confirmed it was a letter from my sister Celine. I sprung out of my chair, closed my office door and sat back down to take in every word of the letter.

Jack, I was so pleased to receive your text. I have missed you so much. I am really struggling with what we did together. To make matters worse, I still have not been able to get my husband’s attention. I think I’m too late and I can’t reach him anymore. Either that or he has found someone else to satisfy his needs. It also doesn’t help that I can’t get you out of my mind. I have always loved you as my brother but now I find my feelings confusing and I don’t know what to do. I don’t even know how I could look you in the eye knowing that I have felt you deep inside of me. I can still smell your body. I can still taste your cum in my mouth. I dream about your beautiful cock in my hands. I’m ready to go insane. Please give me some time to figure this out and find out if my husband is cheating on me. Be patient my darling brother. I hope to see you sometime soon. To be safe, please shred this letter after reading it. I would die if anyone ever found out.

I must have read her note fifty times. I could smell her perfume off the paper. I didn’t want to destroy it but Celine was right. Absolutely no one could ever know about the two of us. As I placed the letter into my shredder I started to wonder to myself how Celine’s husband Tim was able to resist her in the sexy lingerie that we had bought together. Maybe Celine was right. Maybe her husband was cheating on her. My aching heart quickly turned to anger at the thought of that douche bag cheating on my sister. Yeah, I know it’s pretty fucked up to be angry when I had sex with her too. Nevertheless, I decided I was going to help my sister find out for sure.

At my work we have a network of trucks that we have to keep track of at all times and I took it upon myself to go down to our garages and steal one of the tracking markers we use. Instead of programing it to our server, I programed it to my phone. I then drove down to Celine’s husbands work to pay the bastard a visit. He seemed like a pretty happy guy to me and it made me want to punch him in the face with his shit eating grin staring back at me. On the way out of his building, I found Tim’s car in the parking lot and attached the tracker underneath his back bumper. I would now be able to track him wherever he went and if he was cheating he would have to go somewhere else to do it because Celine always worked from home.

At first I didn’t notice anything out of the ordinary but it was the frequency of one destination that made me think was a little weird. Both Celine and Tim had their own cars but his car was always ending up at our mother’s address. Celine and I had a pretty rocky relationship with our mother Stacey. Stacey was a serious rock groupie when she was young and pretty much lived on the road with our father who we’ve never really known. Our mother was 16 when she had Celine. They broke up and then got back together a year later and had me shortly after that. As soon as our Mom got pregnant with me, he split again for good. Celine got her good looks from our mother who was now 51 but could easily pass for her late 30’s. They both had similar body styles though Stacey was a little heavier than Celine with slightly bigger tits. There was never any doubt that our mother’s sex life was active even with the absence of a husband in her life all these years.

I wanted to text Celine to find out if she was at our mother’s house but she asked for some time apart so I decided to take matters into my own hands. I parked a couple of blocks away from my mother’s house and snuck into the back yard through a hole in the fence behind the shed. I had to make sure none of the neighbors saw me because they all knew who I was. I creeped around each window on the ground floor but couldn’t see anyone in the house but I could see Tim’s car in the driveway. I knew if I went into the detached garage and go up to the second level, I could get a pretty good view of my mother’s bedroom window. As I crept up to the window my heart was busting in my chest. I crouched down and slowly raised my head to get a view without showing myself.

What a saw startled me and confirmed my suspicions, my sister’s husband was fucking my mother. Through both windows I could see Tim standing with his pants around his ankles thrusting his cock in and out of Stacey’s waiting mouth. Tim had his hands wrapped around my mother’s long flowing hair as he fucked her mouth. My mother was completely naked on her knees with a blindfold covering her eyes and her hands seemed to be bound behind her body. Her large tits were lightly bouncing even with the hard thrusts which made me think that her tits were still pretty firm for a 50 year old woman.

I had confusing feelings about seeing all of this as I was mad as hell for two reasons, one Tim was fucking my mother and two he was cheating on my sister. On top of that, my cock was starting to swell in my pants as I was becoming aroused by what I was watching. There was no way Celine was going to believe this without some proof so I held my phone up to the window and started recording video to show my sister. I know this would absolutely crush her.

I watched Tim lift my mother up from her knees and positioned her facing me in the window. Our garage is surrounded by huge evergreen trees so unless you were in the garage like I was, no one could see my mother in the window. Tim forced my mother to bend over and he started slapping her ass checks hard. My mother yelped with pleasure with each slap. It appears she likes things a little rough.

Tim balled up his fist and started to punch Stacey in the ass. After each punch, he would hold his fist against her ass which left me with the impression that he was trying to get his whole hand deep into my mother’s cunt. Each hit seemed forceful but it only drove my mother wilder. Stacey’s face looked contorted as she desperately tried to take Tim’s whole fist in. I could faintly hear Tim screaming at her demanding her to engulf his fist into her swollen cunt. Tim held on to my mother’s bound hands as he finally appeared to have inserted his fist inside of her.

From my position it looked like Tim was starting to ram his fist in and out as I watched my mother’s tits sway in the window. My cock was starting to hurt from the constraint of my pants and the fact that I hadn’t had sex in almost a month. I thought I was going to lose it as I watched my mother obviously scream out an orgasm. You could see her trembling in the window and I’m sure he was coating Tim’s fist with her juices.

As soon as my mother was done it appeared as if Tim stuffed his cock deep into my mother’s ass. Holding on to her bound hands it looked like Tim was going for broke. There was nothing gradual about it and there was no working up to a heightened pace, it was just all out slamming. My mother was helpless to this punishment as Tim had both his hands wrapped around Stacey’s bound hands as he ground her ass from behind.

One deep thrust and I could tell Tim was dropping his load into my mother’s ass. I wanted to pull out my cock right there and jerk myself into a frenzy. Tim pushed my mother to the floor and flicked his dripping cock over her to let her know he was done with her. Then to my surprise I watched him reach back and turn a video camera off. I didn’t see it in the beginning because the two of them were blocking the camera. I could see it was connected to a laptop but I couldn’t see the screen. Tim unbound my mother, she took her blindfold off and the two of them were obviously watching themselves on playback smiling.

Tim was done with his sex slave lunch and I waiting in the garage until I heard his car pull away to go back to work. I looked at my watch and knew that Celine would probably be at home alone until their kids came home from school so I decided to pay her a visit and show her the evidence of her husband’s affair. It was an uncomfortable drive to my sister’s house because this news was about to break her heart. It was also uncomfortable because my eight inch hard-on would not subside.

I rang Celine’s doorbell and when she opened her door and saw me she started to cry. “Oh Jack, thank God you are here. I’ve missed you so much!!” She pulled me inside, closed the door and threw her arms around me. She hugged me tight and her perfect tits pressing up against my chest wasn’t helping my stiff cock. Celine obviously noticed too as she separated from me slightly looked down to my crotch and said, “Happy to see me too I can see” She then went back to hugging me and pressed her pelvis up against me which drove me nuts.

After a little bit of awkward conversation, I advised Celine of what I had discovered, she was understandably shocked. “No, it can’t be her. It can’t be her. I thought Tim was cheating but with my own mother? I don’t believe it. It can’t be true.” I had expected this reaction so I said to my sister, “You better sit down, I have something to show you.” I brought up the video on my phone and handed it to Celine. Her eyes went wide as she watched her mother get pounded by her own husband. She was hurt but also confused as to how violent Tim was with her mother. “I never knew Tim liked it so rough. He was never that way with me. I don’t understand.” My phone was trembling in her hands but she continued to watch just as I did. I thought for sure she wouldn’t have watched the whole thing out of disgust but she did right to the end.

She sat there silent for a couple of minutes and I didn’t say anything as she needed time to take in everything she had just seen. The two of us were startled when the phone beside her started to ring. Much to the surprise of both of us it was Tim on the phone. I watched Celine silently mouth to me, “It’s him!” Tim was going on like nothing had happened and what happened next surprised the shit out of me. Celine calmly said into the phone “Explain to me how to do that step by step, I’m sitting at the computer right now.” Apparently Celine had left a message on Tim’s phone while he was fucking our mother that she needed his help fixing a computer program. I was standing in front of Celine trying to hear what Tim was saying.

Celine placed the phone in her shoulder to free up her hands and she pulled me towards her. She quickly undid my pants, pulled them down and wrapped her hands around my stiff cock. “No wait, I didn’t get that. Start from the beginning again.” She said to Tim while smiling at me.

Celine squeezed the head of my cock and flicked her tongue to get a taste of my pre-cum. She then began to jerk my cock with both hands lightly at first. She was looking up at me from her sitting position and I was staring down at her from my standing position taking in the wonderful cleavage from her tight scoop-neck t-shirt. My sister knew how much I loved her big breasts and smiled at me as I took in her flesh. She pulled at her shirt fabric and shifted it under her black bra to give me a better view of her tits overflowing in the lace.

Celine released her grip on my shaft and cupped both of her breasts. I lowered my body and inserted my cock between her tits. My shaft felt so good wedged between her tits and I started to fuck them while she held them in place. She continued to get fake instructions from her husband over the phone while I pumped her tits with my cock. The thought of Tim being on the phone with her while I fucked her tits was so exciting. “Can you hold for a second Tim, I’m just going to reboot the computer and then I’ll let you go once I know it’s working ok?” Celine said to her Husband. She then covered the receiver with her hand looked up at me and whispered, “Cum all over me while I still have him on the phone. I want it all over my face while I’m talking to him.”

I picked up the pace as my cock slid in-between my sister’s tits. “Ok, I’m back Tim. It’s almost booted up.” Her eyes were piercing and she now had her mouth wide open for me. I put my hand over my mouth to stop me from grunting into the phone as I released huge strings of cum covering her face, her mouth, her hair and finally onto her tits. The load was huge and Celine couldn’t believe how much was covering her face. “Ok Tim, thanks see you tonight.” And then she hung up.

“Can I take a picture of you?” I asked. Celine passed me my phone and I snapped a couple of picks of my cum covered sister. She stood up to head to the bathroom to clean herself off when the phone rang again. This time it was our mother Stacey on the phone. She said hello to her and I chimed in beside her “Hi Mom!” I looked at Celine and mouthed the words, “Keep her on the phone” Then I dropped to my knees and pulled down the shorts my sister was wearing. Her panties had a big wet mark in the center and I brought my face closer to them. I inhaled deeply and then pulled her panties down.

I pushed her legs open and buried my tongue and lips all over my sister’s pussy. I grabbed the cheeks of her ass and forced my mouth in as far as it could go. I deliberately searched out her clit and started biting into it. Celine was having a hard time trying to keep her voice steady as she spoke to our mother on the phone. I wanted my sister to cum and try to talk at the same time. She was soaking my face in no time and I could hear her trying to say to Stacey, “I know Mom, we’ll come and visit you real soon but I have to go now” I lapped up as much of her juices as I could and Celine hung on for dear life.

“Nobody can make me cum like you do Jack” she cooed as I finally released my mouth from her ravaged slit. “Ditto Celine. You are the perfect woman.” I answered. Once we cleaned up we talked about what we were going to do with our situation. We came to the conclusion that the two of us could stay happy in our situation since we each serviced our hungry needs. We realized that our families would never be suspicious of how much time we spent together since we were brother and sister. We had our kids to think about so separating from my wife and her husband didn’t make sense if we were happy together and we could see each other whenever we wanted. The excitement of it was a lot of fun too. There was the question though of what to do with our mother and Tim. That would take a little more thought.

The first thing we wanted was to get access to our mother’s computer to find the video they shot or any other videos we might find on there. We arranged for our mother to take the kids to the movies on Saturday, sent my wife to a spa day and sent Tim golfing for the day with his buddies. This left Celine and I time to tear apart the house for anything we could find.

As we walked up the stairs of my mother’s house, Celine reached out to grab my hand, looked at me and said, “You are my lover now Jack and I couldn’t be happier.” I was prepared to hack her computer if I had to but the second password I tried worked. It’s true that people don’t put a lot of thought into their passwords. I opened up her drive and started opening up files to look for any videos. I couldn’t find anything visible so I opened up her video player and clicked on the last one played. A warning came up that indicated it was not on the drive. Hmmn, maybe my mother was smarter than I thought. No she wasn’t, there was one cable sticking out of the back of the computer with nothing attached to it. This could only mean that she had an external drive somewhere.

Celine and I started in our mother’s closet rummaging through boxes and shelves but couldn’t find anything. “I bet you if she has any sex toys, the hard drive will be there.” I thought out loud. “I keep my vibrator in the underwear drawer. Check there.” Answered Celine. I opened a few drawers and on the third one I found her panties and bras. I pushed them aside and sure enough there was a bottle of lube, a rather large dildo, a vibrator, various blindfolds & rope plus a small black box. I opened the box and there it was, an external hard drive.

I connected the drive, opened it and found 72 videos all listed by date. The oldest was over two years old. “Which do you want to see first Celine?” “Click on the first one and move along from there.” Replied my sister. We both sat of the bed across from the computer and clicked play on the first video. It felt a little weird watching Tim fuck our mother but as soon as the first one was over Celine turned to me and said, “Next one now.”

We watched four in a row and surprisingly I was really starting to get turned on. I got up to the computer and clicked on the next one but instead of returning to the edge of the bed, I sat up near my mother’s pillows and made myself comfortable. Celine was still sitting on the edge of the bed and turned her head back to look at me. With a devilish smile I undid my pants and pulled my rock hard cock out. I looked at my sister and then returned my gaze to the computer screen and started to jerk my cock.

Celine climbed up onto the bed and stood on all fours and watched me stroke my own cock. Her tits were hanging out of her blouse and she took a free hand and slid it under her skirt to rub her panties. She would watch me tug my meat for a bit and then turn her head to watch the screen as her husband fucked the shit out of our mother.

Once the video finished, I got up, turned the next one on and then grabbed my mother’s vibrator and threw it to my sister. Celine propped herself up beside me on the bed, pulled up her skirt and pulled down her panties. I heard the vibrator click on and I watched my sister insert it to her waiting slit. She watched me jerk off as I watched her work her cunt. “Nothing could get me more excited right now than my brother jerking off beside me.” She said.

I reached over and started to run my fingers around Celine wet cunt fighting for position with her own hand. Celine reached over and grabbed the tip of my cock as I worked my own shaft with my hand. The video had finished but I wasn’t getting up. My eyes were glued to my beautiful sister. I could tell she was getting close and her tits were really starting to bounce in her blouse. To help her along, I let go of my own cock and started to finger fuck her pussy while Celine worked her clit with the vibrator. I watched my sister squirm, shiver and convulse and cum started to explode all over her inner thighs.

Celine looked at me said nothing but opened her mouth and extended her hands out to me. I climbed on top of her chest and stuffed my cock into her open mouth. Celine hot wet mouth felt heavenly on my thick shaft and you could tell she wanted to please me so bad. Her head bobbed and bounced off the headboard and she tried to take more of my eight inches into her mouth. She couldn’t take it all but I didn’t care, I was close to filling her throat with my spunk. Just when I thought it couldn’t get any better I started to feel a little pressure against the rim of my ass. Celine momentarily stopped sucking to look up at me as if asking permission. I smiled and lowered by asshole against what I thought was her finger but then I heard the vibrator switch back on.

While holding the tip of my cock in her mouth, Celine began to fuck my ass with the vibrator. This was like a dream to finally have someone that wanted to push the boundaries of what could be possible with sex. I’ve played with my rim while jacking off before but to have my sister’s mouth around my cock, stuffing the tip of the vibrator in my ass, was beyond anything I’ve ever experience before. I began to fill Celine mouth with my seed but there was way too much coming out of my cock. It started to slide out of each corner of her mouth and roll down her neck. She wouldn’t release her mouth on my cock though, she tried to take as much as she could until I squeezed out the last drop.

We lay on my mother’s bed sweating and breathing hard for half an hour completely satisfied. “It keep getting better and better with you Jack. I’ve never been this sexually fulfilled before.” Celine told me. “There is so much more I want to do with you and I will but right now we should figure out what we are going to do with this hard drive.” I said with a lecherous smile.
