When I was about 20 and was a hot bloodied young stud who thought of sex 24/7, I worked in a garage in the offices. Most of my colleagues were women - most of them married. We had a switchboard operator who was married to one of the mechanics and I used to spend my lunchtimes sitting with her chatting in her tiny booth. It was extremely cosy and she was always asking what I’d been up to and seemed to pry into my many sexual conquests and always wanted to know what I’d done in detail. Occasionally if she was eating and someone called, I would help by taking the call and directing it to the right extension. To do this I had to physically sit on her lap whilst operating the switchboard. One day while doing this, she tickled me around the waist in an attempt to it me off whilst answering the phone. This tickle when right through me and made me shudder with delight. She assumed I liked it and continued doing it but increased the range along my waistband. My cock was erect in seconds and she sensed my arousal. He nimble fingers were now around the front of my trousers and she was teasingly easing her fingers under my waistband. I am sure it wasn’t by accident, but the tips of her fingers brushed the top of my cock. She pretended to be embarrassed and apologised but continued touching the top of it. I said don’t stop and enjoyed it. It became a regular occurrence and she ventured further eventually tossing me off to completion. It got round to the works Xmas do which was for employees and partners. The venue was a club in the countryside miles from the garage where we worked and the company laid on a coach to take us from the garage to the venue and then return us to our homes. As I lived at the other side of the city, she offered me a bed for the night which I readily accepted. I’d taken my latest girlfriend along for the night and we dropped her off at her house before returning to where my colleague lived. Once there, I was shown my room and left to get ready for bed. We’d all had a fair bit to drink but nothing untoward was said or done. I went to the bathroom and was returning to my room when Janet came from her room to go to the bathroom too. She was wearing a nightie but I can’t remember much about it as I was more embarrassed about me being only dressed in my underwear. I got into bed and thought nothing of it but several minutes later, Janet appeared around the door and asked if I was ok. I was now naked and had my hand around my cock which was obvious to her as I’m sure she saw me wanking. She knelt by the bed and put her hands under the covers to feel my cock which she rubbed. I was nervous about her husband and told her to stop in case he heard us. She told me not to worry because he was asleep and is alright with it. I didn’t realise in my innocence what that meant but was soon enjoying her attentions. She stopped what she was doing and pulled all the bedding off me revealing my rock hard cock. She said that it was about time she had her share of it and climbed on top of me. In no time at all, she’d guided my cock into her pussy and had lifted her nightie over her head. She was riding me as I stared at her magnificent breasts bouncing up and down. She kept leaning forward and telling me to suck them before resuming her riding my cock. She was loud and yelling and I experienced a woman’s orgasm on my cock for the first time and he cunt gripped me and throbbed as she scream that she was cumming. That was too much for me and I shot my cum into her. She then thanked me and was gentle with me, kissing my cheek and leaving me. The following morning nothing was said and I was nervous that her husband might say something. They made me breakfast and then he went off to work at the garage. It was now Saturday and the offices were closed but some mechanics worked. She then said she was going to have a shower and I should join her. It was an instruction- not an invitation. It wasn’t just a shower she wanted.
