Every rational thought in my head tells me not to. But every sexual need and want in me, tells me to let him fuck my brains out. The person I'm talking about is Kristan my eighteen year old step son. Ever since he caught me masturbating a couple of months ago, he's been flirting with me massively. He's even walked into the bedroom I share with his father, totally naked sporting one of, if not the biggest hard ons I've ever seen.
Last week he text me this long message which I've kept, it reads "Hi Sophie. I guess you know how much I fancy you by now. I wish we'd met before you got with my dad, but we didn't. Still I don't see why we can't fuck one another for fun. I know you've masturbated because of me, I heard you the other night saying my name when you were playing with yourself. My dad goes away shortly as you know for his annual fishing trip. I think we should find out if we both like each other enough to have sex. Hope you feel the same way Kristan x".
The text left me feeling all sorts of emotions, but the overriding one, was one of sexual frustration at not at that very moment being able to suck on Kristan's large cock and then letting him fuck my pussy and asshole. He's right about his father. In four days from now he and some of his friends will take a flight out to their favorite sea fishing place and spend the week. I know I shouldn't think and feel this, but each time I sit near or walk past Kristan now, all I want to do is rip his clothes off and have him lick out my pussy and ass.
I've never cheated on any of my previous relationships and if I could resist I would. The fact is, kristan is such a handsome athletically built young man with a very large cock, I don't know when we're alone this weekend, that I'll be able to say no to him if he asks me for sex.
