“Really?” I inquired with a bit of a smile.
“Oh yea,” she continued while bringing her hands up to maul at her tits. “It was running down my legs out of my shorts as you jerked repeatedly into my panties. When you looked down and began to unwrap them from your dick is when I ran into my room and hid in the closet.” I have to admit that this admission from my sister was beginning to turn me on a bit now. “My heart was pounding so hard when I watched you come into my room and put them back into my laundry basket. I was so excited my hands were shaking.” I could actually feel Karen tremble a little when she told me this part. “As soon as you left I went and picked them up. I was actually a little surprised as to how much cum you had left in them.”
“Well,” I said as I pulled down on her hips, “you were quite the hottie back then.”
“Mmm,” she hummed as she looked down at me. “You know I carried those panties in my pussy for almost three days?”
“What?!” I stated in amusement as I took my hands off her hips and laced my fingers together behind my head. “How did you get them in there?”
For just a moment Karen bit her bottom lip before this wicked little grin came across her face. “When I saw all of that cum in the crotch of my panties I didn’t want to waste it. So, I place them on the top of my bed post with your cum facing up and I sat down.” I couldn’t believe what I was hearing as I felt Karen squeeze my cock really hard. “I made sure to sit all the way down so they were as far up inside me as they could go. Then I stood up and tucked the rest up in there with my fingers.”
I was dumbfounded as I took in what my sister just confessed to me. “And this is what made you want to fuck me?” I asked as her gaze returned to me.
“Well, it was that and the time I watched you fuck the hell out of Becky Blackburn in the garage,” she said as she began riding up and down my shaft again in earnest. “I remember seeing that big beautiful cock of yours stab her over and over between her legs. When she orgasmed and you shot your load into her I knew right then that I had to have you at least once.”
“Really?” I was somewhat amused because I had never imagined my kid sister wanting to have anything to do with me other than to pester me.
“I waited and waited for my chance until your graduation party.” As she said this she brought her hands up to maul at her tits again. “And then, everything just fell into place.”
I looked up at her with new found amazement as she steadily fucked me in a nice slow grind. “I am glad you finally got what you wanted.” I said as I placed my hands on her hips in preparation for another good sound fucking.
“Actually,” she stated as she slid all the way down my shaft, “I got quite a bit more than I had expected.” Suddenly I froze in place. I could feel my heart pounding in my chest as a wave of pure panic suddenly rolled over me. Karen was biting her bottom lip with a slight look of anxiety about her as she mulled for a moment. I guess you could say I knew what was coming. “Do you remember that I got pregnant that summer?”
“Yes.” I responded quickly as I swallowed really hard. “I also remember that you never told mom and dad who the father was.”
“Yea,” she stated as she looked down toward my belly button. “You see, Allison (that’s Karen’s daughter) is not your niece. She’s your daughter.” As soon as she revealed the truth to me she tensed up and froze in place.
I think, at that very moment, my heart quit beating. I really didn’t know what to say even if I could have spoken out loud. All kinds of visions of things that could have been, the missed birthdays, jail time, you name it all flashed through my head at the speed of light. “But why didn’t you say something to me?!” I retorted quickly.
“Oh yea, right…” she stated with just a bit of a huff. “What was I supposed to say? Hey Dave I fucked you really hard when you were passed out drunk and got pregnant? That would have gone over like a ton of bricks.”
She was once again looking me dead in the eye as she just sat motionless on my cock. “Actually,” I calmly stated while pulling down on her hips, “I probably would have asked to fuck you again so I could see just how good your pussy was while I was awake.”
This broad smile came across Karen’s face as my answer touched her hidden feelings. Instantly she squeezed my cock really hard with her pussy before she began sliding up and down again. “It seems like you like it pretty good now,” she stated with a gasp as a small orgasm rippled through her. “You’ve fucked me enough this year to fill up a condom the size of the Hindenburg.”
Karen was right. We had fucked a lot since I had introduced her to the hypnosis program, and never once had I used a condom while we fucked. Was I in for another surprise like Allison? And what about Allison? She was now 40 and had grown up without a father. “So tell me, does Allison know who her real father is?”
“No,” Karen replied as she pressed her crotch down hard on to me only to roll her hips around and around. “I told her that her father was killed in a car accident the same night I had fucked him. That is why I decided to keep her because she was the only remembrance of him I had.”
It was right now that reality hit me in the face like a wrecking ball dropped from an airplane. “Holy shit!” I exclaimed as I suddenly sat up and almost threw my sister to the floor. “You say Allison is my daughter?”
“Yes,” Karen replied as she slid off my cock so she could sit upright in between my legs.
“Are you positive?” I asked very animatedly as the news I was about to tell her was going to scramble our lives in a way she had never even remotely dreamed of.
“Yes, I’m positive,” she reiterated as she now looked at me with a slight bit of worry to her face. “Why?”
I was almost to the point of choking when I looked her directly in the eyes and hammered her with some news of my own. “You know her husband, Kevin … he’s my son. That day you referred to when I fucked the hell out of Becky in the garage. I knocked her up.”
Instantaneously I watched all of the expression bleed out of her face as she now realized that our incestuous daughter was married to her half-brother and they already had 3 kids! We both just sat perfectly still and stared at each other. Again the whirlwind of images and thoughts spun in my head as I tried to assimilate everything I had just learned.
“Holy fucking shit!” Karen stated as her hand went to her crotch only to start feverishly digging around. “That is just about the hottest fucking thing I have ever heard of!” Before I could even formulate a response Karen was back on me. Pushing me back onto the bed she was straddled over my waist with my cock plugging her hole faster than I could react. “We can never tell them,” she quickly blurted out before she locked her mouth onto mine and started to fuck me at an incredibly furious rate. I grabbed Karen’s hips with my hands and began thrusting up into her as hard as I could while she whined in pure bliss. We were both lost into a realm that excited us to no end.
