I was at a job working in a confined space below a counter when the unexpected occurred. I was laying on my back with my legs sticking out, as i shifted position my knee touched a standing leg and as my legs were apart i moved to close them but was stopped from doing so by his foot then he pushed the knee out to spread them further. I always wear short shorts and as i looked towards my feet i realised what he was looking at, my shorts had gaped open at the leg enough for him to glimpse the black lace g-string i was wearing. The thought of him looking started to make me get a hard-on, he then slipped his shoe into the gap and tugged up to open them more. I shifted a little and the gap closed then quickly i put a screwdriver on my groin, it slipped down to the floor. At this moment i reached down hooked my finger under the shorts leg hem, lifted my arse off the floor and pulled the leg up and to the left so he could see the full hardening cock and balls behind black lace. He liked what he was looking at bent over picked up the screwdriver passed it to me, making sure he touched my balls and hardening cock as he did so. As i took the screwdriver from him i raised my groin up from the floor offering him my twitching cock to hold/ feel, he pinched the head between his finger and thumb then squeezed the shaft and cupped the balls. When he stood up he started to talk to some-one on the otherside of the counter, as he was talking he pressed his foot down on my hard cock. After he had finished talking i shifted and said i'll be back in the morning to finish off, as i slid out from under the counter my t-shirt pulled out of my shorts giving him a view of the waist band and the string going down between my arse cheeks, before i got up he took the chance to pat and stroke my cheeks, as i repeated i'll be here in the morning my pencil dropped i bent down and noticed he had a erection in his trousers, I gave it a firm squeeze as i retrieved my pencil. I did enjoy this brief encounter and wondered about tomorrow. The following morning i wore a red lace thong to work. As i was crouching in front of my tool box when his voice commented on my aftershave and a foot slipped under my arse and rubbed up against my crotch.I thought todays going to be interesting iv'e only got a couple of hours at the most. I again slipped under the counter again making sure enough red was showing. It did, the next thing i know was he placed his right leg between mine and slowly prised them apart, as i moved i lifted my groin up so the leg gaped open more showing more red lace. while i was working i looked towards my feet and saw another pair of legs, shit i thought and tried to close my legs, he wouldn't let me move if anything it felt as he was trying to open them more. the other legs vanished from view, it did start to make me horny though, he sensed this bent over and hooked the shorts leg and pulled it up to open the gap more. I reached down lifted my groin and pulled them over to show him my cock and balls behind red lace, he squeezed and stroked me then slipped a note under the thong. He didn't ask me but told me to follow him at 10am ,in brackets [no questions]. This made me horny while working and clock watching, about 9.55 i felt him tap my thigh with his foot. Time to follow my orders, he started off towards the back of the building were i know theres un-used offices. I followed him in, he told me to close, lock the door and give him the key. I turned and saw him squeezing his hard cock in his trousers. I handed him the key, he put it in his pocket, knelt down in front of me put one hand on each thigh and started to slide them up under my shorts, he started to stroke the lace with his thumbs, then slid his left hand around my thigh till he could feel the lace clenched at my arse. I was rubbing his balls with my foot as he was doing this. he asked me to undo the draw-string, i did as he dropped his trousers i pulled out his hard cock which had pre-cum leaking from it , i licked it and sucked it, tasted nice. He then licked and sucked my cock through the lace before he pulled it out and started to give me a bloody good blow-job, when i was ready to cum he held firm with his lips and sucked, he groaned as i filled his mouth with my cum, he slowly swallowed and told me to turn around and pulled the thong out of my crack and rimmed me, felt really good and would normally expect to feel the cock next. he said i didn't have to blow him, his cock was still dripping pre-cum and couldn't let it waste so i sucked and wanked him , he came in my mouth, tasted nice, he told me not to swallow but lifted me up and asked me if he could snowball with me and sucked what was left of his cum out of my mouth. I went to clean up where i was working, packed away tools and left, didn't see him around. I did not expect that day to start that way and still don't know who else was there, but well worth it and could do with more jobs like that.
