Part I - "A new girl in the office" "There was a new girl in the office today" Helene turns from the window and looks at me lying on the bed. Her naked body silhouetted against the light. Last time I saw her her blonde hair dropped in a long fashionably tangled V down her back. Now it is cut into a rough bob. It suits her. She walks over to the bed and runs her painted finger nails up the inside of my thigh up to my balls. Despite the fact I recently came I feel my cock stirring again. As she continues she gently squeezes my balls. "She's cute. Same height and build as me. Long light brown hair. Lots of it - wavy. And pinned back asymmetrically. Not dead pretty but cute." I say nothing just listening. In some ways I hardly know Helene in others we are more intimate than I have ever been with anyone. We met two years or so ago at some function or other and drunkenly ended up in bed. Somehow the one night stand carried on into something bizarre. When she wants me I get an email or a txt telling me where to be if I want a fuck. I've learned to my cost that I have to be there. The first time I couldn't make it I didn't see her for 2 months. Now I drop everything no matter what. It has also been made clear that I don't email or txt without being contacted first. I belong to her. "Great clothes" Helene loves womens clothes. She often dresses up for sex or makes me dress up. Nothing odd, just normal everyday clothes, which is the something thing I find a real turn on. Last time we met, a couple of weeks ago, I got two days notice and a list of clothing items and shops where I could buy them: Black gypsy skirt, Black tights and knickers, knee high brown boots, soft pink jumper with long sleeves and a really high thick roll neck, green parka jacket with a thick fur trim round the hood and soft furry lining and a chunky white scarf. I met her in a quiet spot in the park near my flat. She didn't say a word. Touched a finger to my lips, knelt down, lifted my skirt and extricated my (very) hard cock from my tights and knickers and sucked me off, one hand wanking me off, a finger of the other hand up my arse, till I came in her mouth. She swallowed it all, stood up and walked off. I got an email two hours later that just said: "Fucking gorgeous. Keep the clothes. You will need them." I always keep the clothes. I have a more womens clothes than mens clothes in my wardrobe. "She has this black fur lined jacket. Big furry collar and cuffs." Helene likes fur a lot. At the start of last winter she made me buy a big fake fur coat and a pair of high heeled knee length boots for myself. Cost me best part of my spare cash that month. We met up just dressed in just fur coats and boots. Worth every penny. And that was just the first of many times. "When she was wearing it, before she went out to lunch, all I could think of was being between her legs. Licking her out." She pauses a moment and starts to gently rub my cock with her other hand. "Then I thought of her sitting on you. Astride you with her back to you. Your cock up her arse. Both of your legs apart. Me licking her cunt and squeezing your balls as you gently fuck her. Her wearing that jacket, Collar up - fur around her face and her hands in my hair, Fur cuffs brushing against my skin" Its working. I am getting harder. "That's why I texted you." She smiles. "I want you to do something to help me seduce her. So we can share her" "mmm?" I manage. I am really turned on now as she rubs me harder. I reach out for her but she pushes me away smiling - "don't touch. Just listen and enjoy." She is wanking me properly now and her other hand slips between my arse cheeks. "I want you to write about us. Everything." Her finger probes my arsehole. Just resting gently. Threatening to enter. "All about how you enjoy dressing up as a girl to please me." Her finger is inside now. Sliding up as far as it will go and still she wanks me off. Much harder now. "How you play along with all my games no matter what. All about Rosie and Laura.....and Vicky" A second finger enters me. "And how much I love it. Dressing up myself. Wearing other girls clothes...and fucking other girls" Both fingers are fucking me now. In and out - in time with the wanking. I'm going to come. "and best of all...." I can feel it rising. I hold it off. Pushing. Fuck. Fuck. Jesus Christ.... "You. My pretty girlboy. Doing what I love" I come into her face. The feeling is incredible. Tripped out. Colour. Warmth. Bliss. When I recover myself I see she is grinning at me. Cum all over her face and in her hair. She must have aimed my cock at the last moment. "Fuck" is about all I can manage for a few seconds. Then: "You have never said that before" She leans forward almost leering and kisses me. Tasting of my cum. We snog hungrily. "I needed to make you mine. You know what they say - 'treat 'em mean. keep 'em keen'. It's worked a treat on you. You would do absolutely anything I ask wouldn't you?" I nod meekly "You have fucked boys for me even though you are straight. You go out in public dressed in womens clothes. When you met that girl last year and I amde you to chose between us. you chose me." I look at her. She is right. I would do anything for her. "So what does that mean?" She grins again. "You do know I am married?" I had guessed as much. I nod. "I love him. I have a normal life. Dinner parties. Cinema. Normal. The works. Good sex as well before you get too smug...But" "But..." I smile "But I have a fucking great libido and I want to all the sorts of things I do with you and I am also a control freak. So. You are my toy. you will do anything I want no matter how kinky and this part of my life is nicely packaged away so I get to be normal in the rest of it. Don't you forget it." She is serious now. I change the subject: "So what do you want me to write..." "I am very fond of you." she says very quickly before adding with a grin "Everything. I want you to write everything. All of the kinky little details" "and you are going to show it to this girl?" "Yes. Why not. She is only a temp and she will either go for it or I will never see her again. What's there to lose?" "Fair enough" I smile.
