Mind Field Part Three Ms. Chan showed up on time Monday wearing a lovely light blue summer dress printed with lavender and green flowers. Underneath she was wearing stretchy black panties and a matching bra--I found this out shortly after she showed up. Deborah, stand and face the table, then bend over and lean on it by placing your hands on the edge. Immediately Deb complied, and I pushed her dress up over her behind, exposing her panty-clad ass. She shivered and looked over her shoulder at me, but because of the command she could not get up or pull away. "Mitch, what are you doing? Stop!" the asian woman asked, alarmed. "You are intensely aroused and you want me to have sex with you. Don't you?" I said. Instantly her face flushed, her pupils widened, and she became breathless. "Oh yes. Yes. Please Mitch, do it to me, I have to have it. But please, never tell Carl. I love him." she begged. "Don't worry Debbie. Carl will never know." I assured her, and thought to myself "Or, he won't care when I'm finished with him." She seemed relieved, spread her legs a bit and began swaying her delicious ass before me. "Take my panties off." she commanded. This was a switch! Apparently Deb was forward-thinking and didn't mind playing the aggressor in the bedroom. I obediently placed my thumbs under the waistband and slid her panties off, revealing her immaculate buttocks. She stepped out of her panties and spread her legs very wide. (Debbie always was athletic and fit, I wouldn't be surprised if she had done some gymnastics.) Her right arm twitched as she tried to finger herself, but due to the command her hand was glued to the table. I massaged her buttocks and let my hand slip down between her cheeks, over her wet passage, and touched her clitoris with the tip of my middle finger. "Mmmmm. Good. Keep doing that." she instructed, tilting her pelvis back and forth and pressing down on my hand as I played with her clit. Stand, pull your dress off over your head, and resume the position. Soon that was done, and Deb was wearing nothing but her black shoes and stretchy-black bra. I had her kick off her shoes while I continued to masturbate her with one hand and fondle her breasts through the shiny bra with the other. "That's good. Yesss. Squeeze my nipples. UNNH. Gooood. Oh Mitch. Ohh." You want me. "I want you. Put your cock up me, now!" she ordered. I stripped off my clothes and stood behind her. Inhaling her sumptious, flowery scent, I placed my prick at her opening and pushed. With very little resistance it slid into her wet pussy. The little Chinese woman cheered me on. "Oh yeah. Up my cunt. UNNH. Oh Mitch! God! Yessssss..." she moaned. I was hard as a rock in her tight passage--she was heavenly. I placed my hands on her hips and began with long, measured strokes, but before long I was slamming my cock up her pussy as hard and fast as I could. The only sounds were our grunts and those of her ass slapping into me on each thrust, until she came. "OH GOD! MITCH! I'M COMING! ARRRGH! UNNH!" she shrieked as she shook from head to toe. That's what brought me out of it. I was listening to her come and looking at her muscular cheeks and I suddenly realized that I wanted to take her that way. It would be her first time and considering how tight her pussy was, it would feel amazing for me. Do you have any hand lotion? "Yes, -huff- in my -huff- my purse. -huff-" she panted, still coming down from her orgasm. I slipped out of her and reached into her purse for the lotion. I spread it liberally on my dick which was already wet with her juices, and then applied some to her anus. "What -huff- what are you--" You're still aroused. You want me to fuck you up the ass. She quieted immediately, looked down at the table top and sighed a horny sigh, then arched her back downward to make her anus more accessible to me. She looked fantastic, all lithe and muscular and wearing a sheen of sweat and that sexy bra. I placed the head of my lubed cock at her sphincter. "Mmmmm, yessss." she said softly. There was a lot of resistance as I tried to enter her. Anal sex takes some learning for both partners, but fortunately I was able to teach her instantaneously. Relax your anus completely. You trust me. Ah! That did it. I watched, mesmerized, as my penis slipped into her supple asshole. Her mouth dropped open and her eyes bulged as she was filled in this new way. "Oh my God. Oh God! Mitch! Its... I..." She couldn't find the words, but her face showed pleasure and her eyes fluttered closed as the last of my prick disappeared into her anus. She panted and we rested with my member entirely within her. Then I withdrew and grinned, knowing that the sensation is doubled when withdrawing. Her eyes sprang open again and she went rigid, a thin sound escaping her lips. I felt her asshole spasm around my dick and realized she was coming. The tiny squeak became a loud moan as she came. "OOOOOHHHHH Mitch, do me. Do me up my ass! Oh Yes!" We began slowly but soon I was able to pick up my pace, 'till eventually I was thrusting into her asshole as hard as I could. She loved it. I never had to suggest to her that she loved it, only that she wanted to try it. I lost track of how often she came. I pounded my cock up her ass for as long as I could until I couldn't hold back anymore. "OH GOD Debbie!" I moaned "I'M COMING! I'M COMING UP YOUR ASS!" "Oh yes! Please! Come in my ass!" Deborah Chan cried. With a roar I slammed my cock up her ass and pulled her upright, my hands squeezing her small, firm, breasts through her sexy bra as my cock pulsed and shot huge wads of come deep inside her asshole. She leaned her head back on my chest and smiled up at me as I filled her ass with come, and we kissed deeply. "Thank you." she said sleepily "I needed that." "Thank YOU, Deb. It was incredible." It was then that the door opened. Damn! I had forgotten to tell Debbie to lock the door! Carol Parker, our computer technician, had showed up to do maintenance on the lab computer, and she stood there staring at us with a look of utter shock on her face...
