I felt Katie's hand on my leg.  She had put down the beer she had been holding, and she touched my face lightly with her other hand.  "I want to stay with you," she repeated.  "I want to move in and live here, Uncle Jack."

Her hand was moving up my thigh as I explained to her again why that wasn't possible, and why she had to go back home.  She leaned in, her face closer to mine; her hand brushed lightly against the bulge in my pants.  She smelled wonderful: young, hot, sexy, slutty--she smelled like incest.  As her palm pressed against my hard cock, I tried to get up and get away from her, but she took hold of my arm.  "What's wrong?" she asked, all wide-eyed innocence.

I could barely speak.  "Katie..." I managed, still trying to stand,"Katie...please...can we talk about this in the morning?"

She moved her one hand from my crotch and her other hand from my arm.  "I guess..." she said, disappointed.  She pouted a moment as I got up and walked across the room; I picked up the remote and turned the TV back on.  When I turned back, her pout had turned back to a smile.  She walked up to me--black tank top, black panties, black stockings--and put her arms around me.  "I'm going to bed," she said.  "Will you kiss me goodnight?"  I went to kiss her on the cheek, but she moved her face away--"No," she said, "not like that.  I want a real kiss, Uncle Jack."  And then her mouth was on mine; I knew I should resist, but I couldn't, and I kissed her back, and her mouth opened, and my mouth opened, and her hands moved down to tease my crotch again, and my hands went to grab hold of her ass...she moaned a little.  "Kiss me like I'm not your niece," she whispered.  "Kiss me like you want to fuck me."  I pulled her to me so that my hard cock pressed against her, and we kissed and kissed...

She stepped back.  "That was a nice kiss," she smiled.  "Goodnight, Uncle Jack."  And she walked down the hall to the bedroom, and of course I couldn't take my eyes off her half-naked body as she walked away.  I didn't know what to do--follow her to the bedroom, or just sit down and watch TV and try to compose myself.  I stood there, rooted to the spot, for what seemed like forever; then I saw the bedroom light go off, and knew that she must have gotten into bed.  I took a deep breath, turned off the TV and all the living room lights, and lay down on the sofa...

I waited maybe half an hour.  Then I got up from the sofa, stripped down to my underpants, and tiptoed down the hall to Katie's room.  The door was open; the room was dark, but she had left the curtains open enough so that some light came in through the window.  I edged my way inside the room.  I could see Katie lying on the bed, and after a moment, I could see she was lying on her back on top of the covers, and after another moment I could see she was still wearing the black bikini panties--but nothing else.  I moved closer to the bed, holding my breath, not able to see if she was awake, but desperately wanting to get close enough to see her tits.  My cock was hard and straining inside my underpants.  I approached the bed and looked down at my 16 year-old niece, her perfect small tits, the hard little nipples...

"You took so long," Katie whispered.  "I almost fell asleep waiting for you."  She slid one hand down her body and slipped it inside her panties.  "Take out your cock," she said.  "I want to watch you jerk it off."

I heard the words No No No very clearly inside my head, but I ignored them.  I pushed my underpants down and stepped out of them; Katie stared at my stiff cock as I began touching it.  "Stroke it for me," she ordered.  "Stroke that fucking cock."  I don't know how long it took; I masturbated standing beside the bed, and Katie was masturbating lying there in front of me (she kept her panties on), teasing her nipples with her free hand; then, she took that hand and lightly touched my balls as I pumped away.  I was saying things like "You're so fucking sexy" and "I want you so fucking much," and Katie was moaning "I'm wet, Uncle Jack, you make my pussy wet."  And then she took her hand out from inside her panties, and she held it up to me--"Taste it," she said.  "Taste my pussy and tell me how good it tastes."  I grabbed her hand and licked it, put her fingers in my mouth and sucked and licked her pussy juice from them, and as I did, I felt my cock ready to explode--"I have to cum" I gasped, and Katie said "Cum on my tits, Uncle Jack," and I did...

Katie smiled.  "I bet that felt good," she said.  "It looked so fucking hot."  She scooped up some of my cum with one finger, put it to her mouth and tasted it--"Tastes good," she said.  She smeared the rest of my cum all over her tits...then she asked me to get her a wet cloth and a towel so she could clean up.  I was in a daze, stunned by what I'd done, by what I'd allowed to happen--Jesus, I thought, I just jerked off onto my niece.  I got her the cloth and the towel, and she cleaned up the mess, handed them back to me, and said, "Goodnight, Uncle Jack."  I left the room and went back to try to sleep on the sofa.
