One of the rare opportunities where Adler and I were late in the office together. Very late. And very alone.I was in my chair when she came over, this sauntering stride she has, confident and aloof. As she walks behind me, her hand strokes my shoulder and encourages me to turn the chair to face her. She’s biting her lip and staring at me, and this is stirring thoughts of opportunity. I bite my own lip and take her hand, turning my chair as I do, encouraging her to come to the desk and to sit on the edge of it.As she is perched I stand and press my hips against hers, closing the gap between us and kissing her hard on the mouth, her tongue meeting mine. My hands roughly take her chest, feeling the fabric of her dress over her gorgeous tits, but no bra? Did she prepare for this I think to myself? Either way I can already feel her nipples pressing through the fabric against my palms, and I’m sure she can feel how I’m getting harder against her hips.There’s something I wanted to do, here in the office so I see this as the perfect chance. I break away from kissing her and slowly drop to my knees, sliding my hands down her soft legs as I go. Her hands are holding the edge of the desk and she knows why I’m here, so Adler brings her legs up over my shoulders, the loose dress now being moved out of the way.My teeth, my tongue, my lips are teasing the inside of her thigh, my hand firm on her other leg, and as I slide this up her thigh I notice her underwear isn’t there, she definitely prepared for this before she came over. That turns me on more and I can’t resist flicking her clit with my tongue before clamping my lips around it. Slow kisses and long strokes with my tongue to begin with. Soon I introduce the hand that was on her thigh, using two fingers to gently penetrate her, pressing them inside her up to the knuckle. She lets out that trademark low moan as my fingers are inside her and my tongue is circling her clit.This is what I wanted, I want her to imagine this was a kind of functional orgasm. Her at work, bored and trying to work through some problem, her hand absentmindedly going to her clit, wishing she could wank to relieve some tension and be able to concentrate. But now I’m helping her, so rather than her fingers, she’ll be cumming on mine, and my tongue.I plunge my tongue inside her and taste her, my hands back to holding her thighs. Her breathing changes, she likes this. I pick up the pace, more furiously eating her cunt now. But I need her to cum, so i go back to her clit with my mouth, sucking, nibbling and licking her now swollen clit, and pressing more fingers inside her, pumping her. My tongue and my hand working together. I feel her legs press on my shoulders and can see her hands gripping the desk now as she is getting closer. I try to keep the pace despite just wanting to get faster and just burying my face in her wet cunt right now, but her orgasm is more important than what I want. I feel her lurch forward, her legs trembling, the sound of her breathing disappeared as the orgasm hit, strong wave by strong wave, her legs now squeezing me as my fingers are still pumping her.I started to slow down, allowing her legs to disengage from the grip they had me in before stopping and standing up. She’s sat there, breathing heavy, her mouth slightly open, her eyes wide and her pupils dilated. But there’s something there that’s telling me she wants more. And I definitely do, my erection is almost painfully contained in my trousers still.Adler tried to hook her heels behind my legs as she’s unbuttoning my trousers, easing them down, exposing my cock. But with a bite of my lip and a shake of my head I let her know it’s not happening that way. I pull her off the desk so she’s now standing, and then turn her around. In that movement she has now slightly lent forward, but I put my hand on her back to bend her over. I lift up her dress, getting a glimpse of her pert arse. My hand is now guiding my cock into her, feeling her wet opening, and then slowly pressing myself in to her tight cunt.By this point, I’m just inside her but I need to fuck her. This isn’t about wanting to make love to her, this is about fucking, and now Adler was mine. She wasn’t a friend, or a person I knew, she was a part exposed, dripping wet, desk bound sex toy. I start with long languid strokes, aware she has not long cummed so wanting her to feel every inch of my moving inside her. My hands are on her hips pulling her towards me with each thrust, her hands are on the back of the desk, her tits are firmly on the desk and her head is to the side so I can see her face. My strokes turn to faster, harder, more punishing blows, me just wanting to fuck her as hard as I can, relentlessly pounding her. My cock is already throbbing inside her, and she is up on her toes, changing the angle I’m at, pushing me closer and closer. I can’t hold off any longer, and I unleash my orgasm inside her, deep inside her. I can feel it bursting out of me and flooding inside her warm, wet cunt. The mix of hers and mine is now spilling out.We slow down and catch our breaths, I’m still inside her and she’s still bent over the desk. After a moment she says:”Holmes, I’m working late every day this week”.
