It was yet another hot stuffy day in the office where I worked as the Head Receptionist. Another day without airconditioning thanks to faulty electrics. So many people in and out of the office going about there business when suddenly a person appeared in full leathers, helmet, gloves and boots, the whole biker kit. He removed his helmet and announced he'd come to collect a parcel as per an earlier call. I looked around but couldn't find any message or note to back this up. Eventually after much messing about on the phone I located where the parcel was kept and proceeded to show the biker down to the stores. He looked fed up. "Just follow me" I announced, and he did (he wasn't bad looking either). He had brown hair and eyes with a slight rugged growth, just like he hadn't shaved in a day or so. He announced his name was Darren and that he was fairly new to the job but getting the hang of it, (I think he was nervous around me). I asked if he was hot in all that leather and apologised for the heat, explaining about the airconditioning fault. He was hot and I noticed him looking me up and down. It's days like this I was grateful for wearing a nice tight white blouse and short skirt, it gave me plenty of ventilation. "I'll just get your parcel for you if you want to wait here" I said. "Oh ok no problem" he replied. Again I caught him checking me out as I bent down to get the parcel, then "ouch, I've broken a nail" I said, annoyed at how long it had taken me to grow them this long! Darren rushed over to assist me and as he bent down we bumped together and laughed. He was looking down my blouse at my breasts all hot and sweaty with the heat. "Sorry" he said, "no problem" I replied as we both stood up. Here you go this is what you came for I announced. "Do you mind if I take my jacket off" he asked, "and... do you have a glass of water please" he continued. "No problem let me get you your water" I replied, I began to imagine pouring the water all over him and watching him cool down. I bent down to open the pack of cups up for the water dispenser then suddenly I felt a hand.....it was on my bum moving in a sexy seductive way. My nipples erected immediately, my heart rate pounded through my body and I became wet instantly, this must be what they mean by chemistry. "Do you mind" Darren asked, "only I couldn't resist, you have a lovely bum, nice and tight and round", "Thank you" I replied but not sure what to do, nothing like this had ever happened to me, maybe my friends but definately not me. All I could think of is what if somebody comes in, this is a public use area, then suddently I became so aroused, the very thought that we may get interrupted drove me wild. By this time Darren had his fingers under my pants and was slipping his hand up and down my crotch area, my wet area. I slowy turned around to face him and lifted myself up on the nearby shelving, opening my legs for easier access. His cheeks where flushed so I undone his top to reveal his lovely chest, slightly hairy but with an little line of hairs right down to his belly. He leant over and began kissing my neck with little nibbles, his hand cupping my crotch and teasing me with fingers around my clit. Oh my god, this is amazing I thought, I don't think I've ever been this wet. I reached out and undone his buttons on those lovely black leather trouser. I could feel his manhood throbbing up against his pants. It needed to be released to run wild. He inserted a finger and teased slowly in and out while continuing to kiss me and plump my nipple with his other hand, he was very sexy, I could feel his hot breath on my neck as his pulse raced. I grabbed his cock like a wild woman, like I'd never seen once before. Wow it was hard, long and thick, but very very hard. I began to stroke it fast, "slow down" he asked, "I'm in no rush are you?", "no definately not" I replied. He moved his head down to my breasts and began licking my nipples wildly sending my body into shocks and thrusts I'd never known. My vagina was throbbing and lusting for his cock inside, I was slippery wet and wanted it hard and bad now. I pushed his head further down and he got the message, he began to lick my clit and cupp it with his lips, wow my clit throbbed with anticipation. He rose up licking his lips, I watched him lick my juices from his lips. Suddenly he got his long hard cock and thrusted in me, I could feel the heat and it pulsed inside me. He once again began slowly, almost teasing me but by this time I was so aroused it wasn't going to take me long before I'd be screaming. "Mmmmmmmm your so wet and warm" he said, my nails dug into his back as I hung on or dear life, would this shelving hold upto the job? The heat between us was amazing and on top of the heat we both had beads of sweat pouring down our bodies. He began to speed up then slow down making me beg him for thrusts. "Please, give it me, let me feel you thrust and fuck" I asked. Our rythm got faster as he clamped me to him with his hands on my bum forcing me forward and back, my legs wrapped tightly around him, once of my heels fell off. Suddenly I heard the store door close, did somebody come in or worse....go out, how much did they see or hear. I really couln't give a hoot at this point I just wanted his cock hard and fast. My nails dug into his back like claws and I listened to him moaning with pleasure, I was about to cum, and not quietly. He must of felt my begin to twitch and started fucking me furiously, "yes bitch do it, cum on my cock....now" he shouted in husky heavy voice. I did as he asked and started thrusting on his cock, my body twitching, I felt like I was going to pass out, and as I screamed in exstacy he ploughed into me making me scream more. He fucked like a wild animal and I felt my cum cover his cock, he wouldn't stop he was close too, then my suspicions where right, somebody had entered stores earlier and I could see them peeping from behind the archive shelves, they must have been watching us all this time. I stopped with embarrasment and pulled my skirt down, poor Darren didn't know what had happened and looked confused. "Don't stop on my account" came a voice from the back, a male voice. "I didn't mean to distract you, I was enjoying it" he said. As the shadow drew closer I noticed it was my boss, Clive. "You don't mind if I watch while you finish this poor man off, do you?" he asked. Darren still throbbing hard with pre-cum oosing from his cock replied "I don't mind if she doesn't". Once again I was immensely aroused by this thought and popped myself back on the shelves ready for action. As Darren forced his way in and began thrusting, I noticed Clive was wanking, almost fucking his hand, this was fantastic, I felt like I was in my own movie. I grabbed Clives cock and wanked him while Darren got faster, he must be close I thought. Darren came and fucked like a rabbit, while Clive was close, he climbed up on the step so his cock was level with my chest, he poured his cum all over my tits, down my cleavidge, it was hot, running over my splirting everywhere. Darren pulled out and pulled his pants up, grabbed his shirt and dressed. He grabbed the parcel and left the stores. This left me and Clive, my boss. I felt awkward, what now do we talk or walk. I got up cleaned my chest and pulled my skirt down trying fix myself and walked away back to reception.
