I worked at a local gym for a couple of years in the evenings and weekends while I was in the sixth-form at school. While I was there my boss, who was approaching forty, used to flirt relentlessly with the younger staff (males and females). She would turn up to lifeguard training in tiny skimpy bikinis and spend most of the time trying to get a reaction out of the guys (which was sometimes difficult to hide for a hormonal teenager as I was at the time).
I left for University and never thought much of it again until the following year when I took up a summer job at the same gym. The flirting immediately restarted, but this time she had taken it up a level.
One evening on my last week before going back to uni we were the only two left in the building. She asked if I wanted to get a drink and take it to the hot tub with her as a send-off before I left again. I grabbed a couple of beers from the bar and took them to the spa room. I jumped in the hot tub and waited for her. She came out of the changing rooms in a tiny bright red bikini that I'd never seen her in before. It looked stunning.
She sat down in the water next to me and we got chatting again. She quickly turned the conversation sexual and started asking what new tricks I'd learnt from the girls at uni. I told her I didn't have much time for girls (mainly because I was embarrassed to be talking about my sex life with a much older married woman!).
The next thing she said had me instantly hard: "Maybe you just need an older woman to pass on some of her experience."
I was dumbstruck and couldn't hide the tent in my swim shorts. She moved a bit closer to me and we clinked beer bottles. Then she took a swig, leaned towards me, put her mouth over mine and passed the beer from her mouth into mine. That was it! I couldn't hold out any longer! I pulled her body tight against mine and kissed her with raw animal passion.
Within seconds she was untying my shorts and pushing them down. Her hand went straight to my cock and she started slowly pumping it as we kissed.
I reached back and untied her bikini, letting it float off in the water. Then I went to work sucking her nipples and kissing her breasts.
"Careful," she said. "You can't leave any marks my husband might see." That's when it struck me that I was messing around with a married woman.
I stopped and said, "I don't think I can do this. You're married."
"Rubbish," she replied. "You've been dreaming about this for years." And with that, she pulled off her bikini bottoms and threw them over her shoulder as she leaned in to kiss me again.
