Babysitter

Back when the kids were small we had a babysitter (Rachel) she was a small petite girl (19) loved to wear short skirts and vest tops when the weather was good.
She had been sitting for us for a few months and often got quite flirty with me.
One afternoon we were invited to a barbeque and she was invited along with us so she could tend the kids whilst we had a few drinks.
Later in the afternoon I saw her sat on the lawn and as I walked over I could see right up her skirt, her little white knickers standing out in the sunshine, I commented that she had everything on show to all on the patio, she blushed and closed her legs, saying sorry, she was enjoying the sunshine. I said don't be sorry I was enjoying the view, she smiled at me and then we sat chatting.
Later that night after the barbeque I received a text from Rachel asking if I would take some pictures of her for her boyfriend, as I was a keen amateur photographer.
I agreed and set a date to got to her place.
I turned up as agreed and she greeted me at the door in a short denim skirt and bright yellow vest top, I asked where she wanted the pics taking and she said the bedroom was the best place, she showed me in there and I set up my gear.
we chatted about what she would like and started with a few head shots.
Rachel suggested a few more risqué pics and set about in different poses, bent over looking back at the camera, sat about on the bed, bending over the bed, but always keeping her modesty hidden, much to my disappointment.
After maybe 100 clicks she sat back and the bed and asked if she could see some, I opened the lap top and plugged in the camera, turning to her to show her the pics taken, she was sat there leaning against her pillows, legs slightly apart and not a sign of any material between her legs, I was gobsmacked that I had run off at least 100 photos and not noticed that she wasn't wearing any knickers.
I told her my feelings and said it was a nice surprise, she followed by asking if I wanted to do some raunchy ones, who was I to disagree.
She once again set about posing, but this time letting her skirt ride up to reveal her trimmed pussy.
I was really engrossed in my photography and it was only when I stopped again after quite a few poses and clicks of the camera, that I saw she had juice running all down her thighs, she was as turned on as me , but I wasn't going to let on.
We did several more and then once again she sat back on the bed, not quite so lady like this time, and her juiced up cunt was fully on display to me.
I turned everything off and put the gear away, all the time trying to hide the fact that my cock was rock hard.
Everything packed away, I told her I must go, but she had other ideas, she said, aren't you going to fuck me.
Once again I was speechless but was horny as fuck.
I put my gear down, dropping my pants to expose my hard cock, there was no hesitation from either of us as I climbed on the bed and slid my hard cock into her wet hole.
The fuck was quite frantic and it didn't take long before I shot my load inside her, it seemed like an endless stream of spunk shooting into her.
I pulled out then cleaned up, on leaving, I said to her you had better jump in the shower, her reply was that she didn't have time as her boyfriend would be home in ten minutes.
As you can imagine I left rather sharply.
