Part 1 (fucking character limits)
Having never quite been able to maintain any sort of monogamous relationship for very long, I was never able to have children, yet I always desired them. It was with this thought in mind that I visited the adoption agency. It was there that all my dreams materialized in a set of unwanted, -conjoined- twins. I quickly moved to adopt them, passing through the background check easily. I had many plans for these beauties but they had to wait.
10 years later, the twins, who I had named Sasha and Malia in honor of then-President Barack Obama, had matured delightfully into two barely pubescent girls. The fact that they were bonded together for life made them all the more attractive. They had a set of budding tits, one per girl, that had just started to make sexy lumps in their shirts. Not for nothing, they were a very erotic sight in a tight shirt and jeans, all of which I had custom made to enhance their attractiveness.
One morning, all my planning had come to fruition. I laid a frilly, white, new dress on their bed with a “Come downstairs, Daddy has a big surprise” note attached.
They came downstairs, head poking delightfully out of the new dress. “What’s the surprise Daddy” they chorused as they stepped through the hall. When they approached the family room I leapt up and tackled them, landing them on the couch. “DADDY!” they screeched as they flew through the air. I gave a mischievous grin as I got up. “Girls, today I am going to teach you about sex. Being conjoined it is different for you and in your case the best way is demonstration. Don’t worry, I won’t hurt you or anything. Just our little secret.”
They looked at each other and grinned. “Daddy we’ve been wanting you to do something like this forever. We’ve started playing with ourselves late at night, it’s kind of difficult because the two of us only have one tingly place and we like different things.”
My cock sprang up upon hearing this. So they have been masturbating! I reached up and slowly pulled the top of their dress down, exposing two small but well-developed tits with small strawberry red nipples. I slowly sucked on one as they gasped and it hardened in my mouth. Malia, who was closest to the free breast, pulled it up and started licking it herself. Then Sasha grabbed Malia’s head and pulled it towards her, giving her a passionate kiss as their tongues began playing with each other. “They must have done this a lot,” I thought, “normally kids this age are very inexperienced.”
I then reached up the bottom of their dress and found their vagina. The girls really needed to learn to shave their pussy, but there was not that much hair yet. I slowly began fingering them, and then slowly worked more fingers in until most of my hand was in their pussy which was absolutely dripping juices all over my hand. "You're supposed to be virgins" I said in a mock stern voice, and they giggled. "We worked up from fingers to bottles, Daddy" Sasha said. "Well then you should be able to accomodate my cock quite nicely" I responded, sliding my pants to my ankles as they cooperated to take off the dress.
Each head looked at each other with a bit of a mischievous yet wondering grin, eager yet curious as to what it would feel to get spread open by a real penis. I took my fully engorged, swollen purple cock head and slid it up and down their labia, rubbing it against their clitoris causing the two of them to both moan in ecstasy. "Daddy put that in me RIGHT NOW!" Malia screamed at me with Sasha's face contorted in ecstatic assent.
I eagerly obliged and slammed my penis deep inside them. Their warm muscles gripped me, better than any single vagina I've been in, with each of the girls clenching their love-sheath in a different area, molding around my penis perfectly. All too soon I felt like I was going to nut. "Girls I've given you a sampling but now I'm going to take this a step further." They looked at each other excitedly. I produced a bottle of K-Y. "I'm going to stick my cock in your butt!"
They both recoiled a bit, the idea of a dick going where they poop not quite appealing. "I promise it will feel good." "Okay Daddy."
I slimed up their ass with the K-Y and then generously lubricated my dick. It slid in easily. "Oh Daddy that DOES feel good" Sasha moaned. Little flecks of poop came out with my shaft then fell off as I plunged back into the twins' depth. "Girls, I'm going to make this feel even better" I said. Both looked extremely eager, since their experience had been nothing but.
From a drawer nearby, I produced two large butcher's knives. I took one, and slammed it up their still-stretched vagina. "OWW!" they both cried, starting to cry as the blade cut into their vaginal tissues. I grabbed the second knife and slid it again into their vagina, then up into their intestines. Blood gushed out of their vagina as they began bawling in pain, my penis still sliding in and out of their ass, becoming slicked with the blood gushing out of their vagina.
In a swift move, I tied the Siamese twins up to the couch. Despite their struggles the bonds held firm. Taking some strong tape, I forced their heads to look at each other. "One of you is going to die, and the other one is going to watch" I said. They attempted to scream or something, but their mouths were taped shut so all that came out was a whimper.
I paced the floor, erect penis bouncing in front of me. Then, a wonderfully erotic idea came to mind.
