She was to quickly discover that she was too clever for the trivial games of children her age and realized it would take a lot to satisfy any curiosit... she had. She was prone to obsessive-compulsive behaviors, cramming her brain with all available information until she mastered the topic she was interested in. She was filled with curiosities and a desperate need for knowledge that ran as rampant as her imagination. She was brilliant and charismatic, she could have easily been the perfect child. Of course we enjoyed 'normal' sex (whatever the hell that is) but we also weren't afraid to get a little kinky. When I told her I sometimes liked to be on the receiving end of anal sex, she quite happily fingered my ass with a well lubed finger to loosen me up and then fucked my ass with one of her dildos while she sucked on my cock. She even surprised me one night during a canoeing trip with a strap-on, the orgasm was incredible and I was so turned on that I stayed hard long enough to bring. " Silly you are my sister. My extra special sister with extra specialbenefits," I kissed her nibbling at her lips. Then Donnie pulled herinto his arms."And I like those benefits too," he assured her. "I'll have someone whocan help me screw her brains out when she needs it, who can remind meof how to be gentle in that most intimate act."She giggled. "Really? You wouldn't think it was g,,," he kissed herlips. "No, besides it's something the three of us share together."She woke me up in the early. "I don't hear any typing out there," Mark called out from his office.I re-wound the tape to find my place and resumed typing. The vibrator immediately leapt to life. I stopped and so did the vibrator."If I don't hear you typing in the next few seconds, I'm going to have take you over my knee at your desk," Mark said."Yes, sir," I replied. The bastard! Somehow the vibrator and my keyboard were linked, and he knew! Well, I would show him. I resumed typing. Normally, I can do about eighty words.
