Squeezing out an orgasm before stepmom duties start

Oh goodness, it’s not very often that I can actually orgasm when visiting him in Wyoming as the 7,000-foot altitude difference between where we live makes it feel like I’ve been shot in the back of the head and that my heart is going to explode when I’m in the home straight to orgasming! So I can normally only take the edge off if I’ve only got a few minutes! Usually takes an hour or more to be able to hit the good spot. If I can at all. Not today! Hoooraaaaaay! Think the knowledge of having to get up and in the stepmom role before one of my stepson’s found me masturbating may have helped somewhat. Who knows though?!
