I was half way up the stairs when I heard her giggle and say, "Keep your hands to yourself Mike. You are just here to see if you can fix my computer p...oblem." Bullshit Marge. If that were all I'm supposed to be here for you would have come to work today in your usual slacks and blouse. You didn't wear that low cut top, short skirt and "Fuck me" heels for any other reason than to turn me on and the only reason for turning me on is so that I can get you off."I moved quietly to the head of the. Snickers and giggles greeted the few who had received their NAKED NOTICES.I closed my locker door and started to lock up ... But then I stopped. A smile turned to a grin as I opened my locker again and unbuttoned my shirt and hung it on a hook. Next my shoes and socks went on the locker floor. My jeans followed and, lastly, I pulled my jockey shorts down and place them atop the pile of clothes. I stood there naked and waited to see what fate had in store.For six hours I submitted to whatever. She trembled in my arms as her asshole slowly gave way. Bit by bit, my cock forced past the tight opening and into the hot, velvety grip of her asshole.She bit her hand, muffling her groan as I pushed deeper and deeper into her bowels. Her juices lubed the way. Which was good, because she was tight. Tighter than her virgin cunny had been last night.Her body spasmed. Her asshole clenching on my dick. I nuzzled to her ear, whispering, “I love you so much, Keily.”“Big sis,” she groaned, moving her. She nodded as if she understood, and I ran my hand down her arm again.Moving forward I was now inches away from her and I could tell she felt a little uneasy, as I moved her hand from her lap she couldn’t look me in the face, I leaned forward and placed a peck on her cheek she turned to face me and I planted a kiss on her lips, as she pulled and turned away from me I turned her to face me again and kissed her again.Pulling apart she said “Stop it I’m your Auntie” as I turned her to face me.
