I Could be a Very Naughty Girl!

So, being a good neighbor, and with definite alterior motives, I gave them a couple of days to get sorted before taking some goodies round and welcoming them.  Allan and Jessica (the parents) are a lawyer and medical doctor respectively, while their gorgeous son Steven, who is taking a year out before going to Harvard (Of course!) They invited me in and uncorked a bottle of very nice red wine.  Steven is going to follow his father into medicine, and they were very interested to learn I am a dental surgeon. They also loved that I had a year at Cambridge. But then....... The door opened an in walked Heather, their eldest child. Heather is 24, and if I thought Steven was an Adonis, Heather actually made me cream my panties. Turns out Heather lives at home too, but hasn’t got a career....more a succession of jobs. She looks like a kind of blonde hippie from the 60s and I don’t think mom or dad approve, really.  I do!  As they chatted, I sat there in an ever-increasing puddle of my own making and my dirty little mind drew up scenarios of having sex with Steven or Heather.....or Steven AND Heather.  I was just at the point of deciding to force my mind onto something else, when Heather flumped down on the couch opposite me, and I got a look up her dress...just enough to know that panties, for Heather, are clearly optional.  My clit jumped and I squeaked! I had to turn it into a cough!  Back at home! I don’t think I’ve masturbated for so long in a single session for a very long time.  I imagined licking Heather to orgasm, and showing her all the kinky (disgusting) things I like, and then I thought of Steven fucking me. I’d spent much of the evening imagining what he had between his legs, and what it could do to me. I imagined seducing him.....him seducing me.....him forcing me....tying me up, spanking me.....ripping my clothes off and screwing me senseless. Finally, I pushed my dildo into my ass and imagined that I had talked Steven into fucking his sister. While his dick was still slippery from her, he fucked me in the ass. I was lying on my back, legs up over his shoulders. Heather, meanwhile, sat on my face. Just as I felt myself about t cum, I held it there, edging, while I imagined her peeing.  The orgasm made me scream!  But what of the future? Will I do anything about my obvious lust? Well, I’m an opportunist. If the chance comes to let either of them see me naked by my pool, then so be it. I love being watched.....in particular, I adore thinking about what someone who has seen me naked will do to themselves afterwards. The boy on the other side of my property has spied on me masturbating, and I’ve spied on him with his girlfriend.  If I get the chance to sneak a pair of Heather’s panties, even for a second, I certainly will, and as for Steven.....would I fuck him for real?  Are you kidding me? In a heartbeat!  Their home doesn’t have a pool, so there may be an opportunity for them to use mine...and my nice new hot tub! Then again, they have a full on gym and sauna, so maybe the arrangement can be reciprocal.  Ooh....the future looks interesting!
