She was rubbing lotion on herself and I could see that her nipples were quite erect. This was absolutely great and got me very excited! A boy’s ultimate fantasy! I watched for a few more minutes, my erection was growing fast… then jan stood up, removed her panties, walked to a drawer and pulled out a small dildo! ( didn’t really know what this was at the time but figured it out later ). She sat on the edge of the bed and gently started messaging her pussy with this device. I could tell by her body language that she was very much enjoying this. She layed back on the bed, her knees in the air, legs spread wide , what a perfect view I had ! Jan sarted to insert the dildo into her pussy very slowly and after just a few thrusts, she began to buck her hips and really get into it. Then she just kinda slowed down and then stood up , put on a robe and went into her bathroom. I could not believe what I had just witnessed ! I have used this mental image for plenty of jack off sessions….a few years later I almost told her about this, but thought it might hinder our relationship, so I have kept it as one of my greatest memories.
