Pandora's Box Opened (part 1)

Where to begin... I met my wife 10 or so years ago when her daughter was 4. Her daughter, I'll call her "Sara". Sara is on the autism spectrum - it's mild but she still has some developmental hurdles. One comes into play here.

Sara is now 14, petite, very cute. and all the pubescent hormones are in full effect. The sensation isn't something she understands well, the feeling of being "horny" lead her to believe there was something wrong "down there" for a time, according to her mother during an awkward conversation.

Well as I mentioned, one of those developmental hurdles is not understanding what's socially inappropriate. The most tame of her inappropriateness is walking around in her underwear, the most wild is her trying to hide the fact that she's playing with herself at random times. It became obvious that she enjoyed orgasms a little too much.

So, fast forward to a few weeks ago, just another day, she was clearly enamored with something on youtube. I asked what her what "today's interest" was, and she said point blank "I want to see a boy's thing." I played ignorant, "thing?", she then pointed at my crotch. "I want to see one. I can't find it" (referring to the website controls we have enabled on her tablet).

I'll skip the back and forth and the slight tantrum she had, to the part where I pulled out my dick for her to see. It quickly became her newest autistic obsession. Clearly I'm playing with fire, I know it, and told her that she needs to keep this a secret if I'm to continue to let her "see" it.

She wanted to know about it all. It was equal parts nonsexual and sexual interest. She came to understand what causes a guy to get hard, what cum is, the whole nine yards. She loved seeing me get hard and cumming. She would stroke and sometimes even suck me when ever I would let her. If it wasn't an obsession it was close to it. Anxiety would kick in when she would come up and rub my crotch through whatever I was wearing trying to get me hard - not even trying to hide it. Thankfully it was never when it was in line of sight with her mother. Most of the time I don't think it was for anything sexual, it was just pure fascination. Several times I had to scold her which made her upset and she doesn't understand why what she's doing is inherently wrong.

In any event, as these things go, stuff escalated. And then the inevitable day came. My wife was out doing something for work. Sara was in her room, clearly having her way with herself, more than just a few times, while not at all being quiet about it. At the time I was trying to work too so it was a bit of nuisance. I opened the door, about to ask her stop, and she was there spread eagle across her bed, headphones on, seemingly unaware that an adult just opened her door and stepped into her room. "Sara." I said, to no effect, I was invisible. She just laid there finger fucking herself with reckless abandon. When I walked closer she noticed me, she froze, her fingers still inside her. She looked at me, then looked down, noticing the effect her display had on me.

"...it feels like." she said. "What?" I responded. "I want to know what it feels like." Again, playing dumb, "What what feels like?". "Sex." as she spread her legs wider,

This was straight out of a teenage fantasy. Feeling conflicted was the understatement of the century. Few times in my life have I been harder then I was at that exact moment.

Reason gave way to impulse. I walked closer, "Take him out." She didn't hesitate - matter of fact, she pulled my pants and boxers down faster than any other girl I had ever been with. "You really want to sex me, you're so hard." "No", I responded, "When a guy is this hard, he really wants to FUCK you." That must've did something because she immediately laid back, holding her knees back and open, her mostly bald pussy drooling over the sheets, positioned invitingly upward.

"Come on! FUCK me!" she yelled, her slit slightly open revealing that she must've busted her hymen at some point. "Please! I'm being good!"

I rested the thick swollen head of my dick on her tiny opening. She squirmed like she was trying to get it in her. "I don't know if you can handle this so I'm going slow ok?" She didn't respond, my words clearly not registering through the headphones, transfixed on the sight of my cock resting on her pussy.

"FUCK ME!"

This girl knew what she wanted. I pushed myself in.

She let out a loud moan as her young tight tunnel stretched to take my thick head. Knowing how eager she was I attempted to tease her, holding my head within her entrance, going no further, ...but she wasn't having it. She clinched the bed in her hands and jolted herself towards me, impaling herself on my swollen shaft. She winced slightly as I hit bottom, most of my shaft now buried inside her, then she started to tremble... she must've been so horny that she came the moment I filled her up.

Clearly though she wasn't close to being satisfied...
