I love the stories on this site and have been masturbating to them for years now. I'm a grad student now, working on my MBA in entrepreneurship, but years ago I used to make money the old fashioned way. Babysitting!

My best friend, Jessica, was way into sports - played everything she could from basketball to softball, field hockey, and even cross country. As a result, when her mom gave birth to a younger sister she wasn't available to babysit as often as her parents needed - but I was.

I know what you're thinking, "wow, another babysitter does the dad story. How lame." but that's not the case at all. And no, I didn't have my way with the infant child either. That's just freaking gross.

No, I was seduced by Jessica's mom, Megan. Back then Jessica and I were fifteen (I'm 23 now) and Megan was in her upper thirties. A rep for a pharmaceutical company she kept herself looking great with Pilates, yoga, and some kind of strength training regimen. She told me she'd never had any work done, but I'm pretty sure she had the girls lifted at some point.

School had just ended for the year and Jessica was off at some basketball camp at UMO for a couple weeks. Jessica's dad was traveling for work (which he did most days of the week) and Megan off at work. It being late June and me being in their lake house on Sebago I was prancing around in a bikini, listening to their stereo and occasionally rubbing myself through the shear bottoms.

I liked to do that... masturbate. Even with a full time boyfriend I still get myself off 3-4 times a week, usually at odd times. That day I did it right. I went through Megan's dresser and found the big blue jelly vibe Jessica told me her mom keeps in there. A couple drops of baby oil and I was running that humming wand up and down my wet slit, the bikini bottoms yanked to the side, moaning up a storm when Jessica's mom walked in.

I don't know how long she stood there, but I looked up and there she was. Hands on hips, legs cocked, staring at me as I held the vibrating head on my clit. I wanted to die, but there really wasn't anywhere for me to go, and nothing on the couch for me to cover myself up with either.

There's not much more for me to say, really. I'm sure you can figure out the rest. Megan was bi, had been since college, but hadn't done much since she married. She taught me how to use that vibrator properly, helped me get used to taking the whole thing inside my, both vaginally and anally. She showed me how to please a woman with my tongue, how to hold off (and build up) an orgasm until it can nearly knock you out. Taught me the joys of benwa balls, anal beads, and even spanking.

Right now I know some of you are out there thinking this is all BS, and that's fine. But for every one of you there are ten more out there getting off, jacking their dicks or frigging themselves thinking about this. I hope you enjoy yourself.
