Elena slammed the door shut behind us and locked it. "Get your ass on that desk, now." Her voice was low and rough, the same tone she used in meetings when she wanted something done yesterday. I backed up until my thighs hit the edge of her big oak desk, heart pounding. We'd been circling each other for weeks, but tonight the office was empty and the tension snapped.
She didn't waste time with soft kisses. Elena grabbed my blouse and ripped it open, buttons flying. My tits spilled out and she latched onto one nipple, sucking hard while her hand shoved up my skirt. "No panties? You dirty little slut. You came in here planning to get fucked." Two fingers shoved straight into my pussy without warning. I was already soaked. She pumped them fast, thumb grinding my clit.
"Fuck, Elena," I gasped, spreading my legs wider. She curled her fingers and found that spot inside me that made my knees shake. I reached for her, yanking her blouse open so I could squeeze her heavy tits. Her nipples were hard under my palms. She bit my neck and kept finger-fucking me until I was dripping down her wrist.
"Turn around," she ordered. I spun and bent over the desk, ass up. Elena flipped my skirt onto my back and slapped my cheek hard. The sting made my cunt clench. She dropped to her knees behind me and buried her face between my legs, tongue lapping from my clit all the way back to my asshole. She licked like she was starving, sucking my lips into her mouth, then spearing her tongue inside me. I moaned loud, not caring who might hear through the walls.
She stood up fast, unzipped her pants, and I heard the wet sound of her rubbing her own pussy. Then she pressed two fingers back inside me while she ground her clit against my thigh. "You want my cunt on your face or you want me to fuck you with the strap?" she growled.
"Both," I panted. "Fuck me first."
Elena pulled her fingers out and I heard her open the bottom drawer. She kept a harness and thick silicone cock in there for nights like this. She buckled it on quick, spat on the head, and shoved it straight into my pussy in one thrust. I cried out, gripping the desk edge. She fucked me hard and deep, hips slapping my ass, one hand fisting my hair to pull my head back.

"Take it, you office whore," she grunted. "This pussy is mine after hours." Every thrust knocked the air out of me. She reached under and rubbed my clit in tight circles until I was shaking. I came hard, cunt pulsing around the thick toy, juices running down my thighs.
Elena didn't stop. She pulled out, spun me around, and pushed me to my knees. "Clean it off." I opened my mouth and sucked the cock that had just been inside me, tasting my own cum. While I did that she unbuckled the harness, shoved it aside, and climbed onto the desk, spreading her legs. "Now eat this pussy like you mean it."
I dove in. Her cunt was shaved smooth and dripping. I licked broad stripes up her slit, then sucked her swollen clit between my lips. Elena grabbed my hair and rode my face, grinding down while I tongue-fucked her hole. She tasted sharp and sweet. I slid two fingers inside her and pumped while I flicked her clit fast. Her thighs started shaking.
"Right there, don't you fucking stop," she snarled. I added a third finger and sucked harder. Elena came with a low, guttural moan, flooding my mouth. I kept licking through it until she pushed my head away, breathing hard.
She wasn't done. Elena pulled me up, kissed me deep so she could taste herself on my tongue, then bent me back over the desk again. This time she worked two fingers into my ass while she licked my pussy from behind. The stretch burned so good I pushed back against her hand. She added a third finger in my cunt and fucked both holes at once until I came again, screaming into the wood.
We ended up on the floor, sixty-nine, sucking each other's clits like we were trying to ruin each other. Elena came first this time, thighs clamping my head. I followed right after, grinding on her tongue until my vision went white.
Later, when we finally stood up on shaky legs, she kissed me slow and dirty. "Same time tomorrow," she said, wiping her mouth. "And next time bring that little vibe you keep in your purse. I want to watch you use it while I sit on your face."
I straightened my ruined clothes, already wet again at the thought. The office lights were still on, but the rest of the building was dark. Elena unlocked the door and smacked my ass on the way out. "Get some sleep, slut. You're going to need it."
