Mom and I entered her bedroom and I instructed her to removed her tshirt and lay face down on the bed sheets. She did as I told her and I removed my tshirt as well. I went into my room and got my massage oil from my bag along with a couple of old sheets from my dresser. I yelled out to my mom that I would be a couple of minutes that I needed to go to the bathroom first. I used this as a ploy to sneak outside her door and peak to see if she would touch herself while I was out of the room. I went to the bathroom and shut the door loud enough that she thought that I was in the bathroom. I then quietly snuck outside her door and watched her.
Just as I suspected, she placed both of her hands underneath her and down to her pussy and was grinding herself against her fingers. She obviously was trying to give herself a quick orgasm before I returned just as I hoped. I watched intently, rubbing my own pussy as she was really humping hard with her butt cheeks clenching tightly over and over. It didn't take long before she was cumming very hard and as soon as she stopped orgasming, I quickly moved back to the bathroom door and opened and shut it quickly and re-entered her room before she had a chance to wipe the cum from her pussy. I was so turned on and wanted to get my hands and mouth on her delicious body.
