I am the father of two children. Paternal twins, a boy, and a girl. Their Mother had left us to be with her girlfriend when they were sixteen, two years before this story. I always knew that the twins were close but on this particular day as I was walking past Karen's room I heard giggling and the door was cracked open slightly. I saw my son, Kerry, on his knees kissing Karen's inner thighs. She was leaning back, her lips parted in pure pleasure. Kerry was wearing her panties, his cock hard as a rock. A purple dildo was sticking out of his ass. Karen's legs wrapped around his head. Karen was and still is very, very pretty and I had fantasized about her often. But the sight of Kerry's long legs and tight butt filled me with sexual desire.
I must have gasped or something because Karen opened her eyes and smiled a sweet smile at me. But went back to holding Kerry's head to her sweet pussy. I backed away and continued on my way to the laundry room where I dropped my pants and exploded with lust thinking of that dildo in my son's ass.
I knew that the twins had a lot of sex that year and the following year too. I knew that losing their mother was traumatic, so I never said anything to either although I also knew that Karen knew that I knew about them having taboo sex.
Every now and then Karen would kiss me like her mother did, open mouth and slight tongue. I always would get a hard cock when she did that but nothing like that hard-on I had when thinking of Kerry and his small hard cock that I saw that day. I would think of my cock in place of that dildo and think of him wearing a skirt and sucking my cock, us kissing making love.
One night I came home late and when I lay down I found my sweet daughter in my bed. At first, I told her to go to her own room, but when I saw her lust filled eyes I decided, why not, so I climbed into bed with her.
She told me how she wanted to make love to me and how she would think of me as she fucked her boyfriend and all the time she was rubbing her sweet little pussy. After a while, we started to kiss. God my sweet daughter knew how to kiss, and soon enough I had my hard cock in her hand. It didn't take long for us to remove our clothes, she then gave me a fantastic blowjob. I held my sweet daughter and told her how I loved her and her brother Kerry. She talked about how she loved me and wanted to be my love toy. So feeling somewhat guilty because I wanted her brother to be my lover, I took her in my arms and pushed my cock into my daughters love hole for the first time. It felt so incredible!
Fucking my daughter like she was my wife!
We fucked like animals and she lay on top of me my cum dripping from her tight pussy, she whispered how she loved me and Kerry. Then she went on to tell me how she and Kerry would fuck long into the night but she thought maybe he liked boys better so she would share her boyfriends with him. And how he loved sucking their cocks with her juices and their cum on their cock heads. I can tell you how that turned me on, thinking of Kerry sucking a cock, dressed up like a slut.
Kerry had naturally long hair full and beautiful lips, ripe and full, long legs and soft skin. Much like his sister. In fact, people would think they were twin sisters.
My cock still inside of my daughters pussy started getting hard thinking of Kerry's dildo filled ass.
Laughing, Karen slid off of me and lowered herself onto my waiting cock where she sucked me to completion.
About twice a week Karen would come to my bed and we would fuck. I always imagined it was her twin brother Kerry I was fucking. I think maybe Karen knew but she never said a word.
About a year after that Karen got a job at some big company in New York City, Kerry was driving her to her new home. Before they left Karen gave me a goodbye kiss full of sweet tongue and ground her body into mine.
I was used to the kisses Karen would give me. But this time, Kerry also gave me a kiss. Full on the mouth. I could feel his tongue as it licked my lower lip and he ground his hard cock into my willing groin.
I remembered Kerry had a smallish cock not more than five inches long, but it filled me with lust. His boyish grin told me he could feel my hard cock against his. He moved his hands down to my butt and pulled me tighter to him and moaned in my mouth. Then with a small shove pushed me away and walked stiffly to the car and his waiting sister.
Later, after five restless nights, he returned. I saw the car drive up and ran to meet him. His long legs swung to the ground and he almost ran to meet me. Our lips met in a hot embrace, grinding into each other. Lips and tongues dancing and exploring each other's mouths. He tasted so damned good. My own son, wanting to suck his dad's tongue. What a nice son I had. And me, wanting my son to fuck me, how totally delicious. I whispered to him that we better get out of view of the neighbors before they saw how we were with each other and he quickly agreed, "Let's go and fuck daddy, Karen said I should take good care of you in her absence," he mumbled looking at me with his beautiful brown eyes.
As we went into the bedroom he already had is pants down showing off his nice slender tanned legs. I noticed his tan stopped as if he wore a bikini to sunbathe in. How could I have missed that! I also noticed he had shaved his balls so that only a thin line of hair shooting straight up, I think they call it a Brazilian Bikini wax. How sexy my son was and still is. My balls were very hairy and had started turning a sort of gray. His sharp intake of breath told me that he fully approved. "I have watched you taking a shower Daddy, but was afraid you didn't like gays, until Karen told me that she thought you might like to, well," he stammered, "maybe have sex with me," Looking at me shyly "I have been eating your cum from her cunt!" he blurted out.
"God, how could any man get so lucky," I thought.
