I have a story with a cute girl, I don't think it's so lewd though.
Back when I was a sophomore in highschool, my mom worked with some older woman who adopted a little girl from Ukraine. She was in the same grade as my younger sister, I think second or third. She was a very skinny girl with long blonde hair, really cute, and her clothes would always look baggy on her.
Anyways, me and my older sister had to babysit her a few times, I think three or four times at most. While my older sister was busy doing whatever onee-chans do, I would watch over them and sometimes join in playing by building sofa and pillow forts.
I think the fourth day she stayed with us, her and my younger sister came to wake me up so they could use all my pillows. I had a morning boner and could not think straight, so I began to wrestle and tickle both of them. I wanted more though, so I slowly made it a really lame game, anything I could to get this girl in the exact position I wanted her in.
I was laying on my back, and put one pillow on my crotch, then told her how to play this game. I told her if she played I would let her use all my pillows. I pretty much told her to straddle me until I told her to stop.
My younger sister told her to hurry so they could use the pillows while watching this little girl smile and straddle me. I was about to cum and I was getting real risque, so I then flipped her over causing her to giggle and laugh, while her pretty golden hair bounced around and she was on her back on my bed, and I gave the last few humps to that pillow and came in my pants while holding her tiny waist.
Right after that, I just started to think "what have I done!". Lucky for me, the cum didn't go through my pants much, but it did make the pillow cover a bit wet. So I took it off the pillow and then gave them my pillows while I went to take a shower.
