I don't want to dwell on what happened but basically we did some fooling around under the covers. We wrestled around, I copped a feel of Karen's budding titties (through her PJ top) and she in turn grabbed me between the legs and felt my boner. One thing led to another. She asked me what I was doing the night that she caught me jacking off in the bathroom and I explained it to her and asked her if she wanted to see me do it again. She said yes so I turned on the nightstand light and gave her a little demo and got her to finish me off with her hand. That's all that happened that first night. I didn't even directly feel any of her underneath her PJ's.
The following night we went further and went to bed naked and we did some more touchy-feely stuff under the covers. This time I did feel her bare tits and she guided my hand between her legs and showed me how she pleasured herself. At the time I was so naive I didn't know girls even masturbated. I think I fingered her to orgasm but I'm really not sure. Karen then gave me a complete hand job, jacked me off from beginning to end. Again it felt great! After that we feel asleep, both still in the nude.
Well now that I got THAT off my chest I'll tell you about my most important sexual milestone, my first piece of tail which came about not that long after the motel incident. No Karen was not involved you nasty person!
