Thinking about a big young cock

So my last post was about me getting turned on about my friends 18 yr old son. I've thought about it....I go to the beach a lot and apparently so does he to skin board (the same one I go to) so I think there would be an amazing spot to show him my dick sucking skills. There is a little board walk where we could walk down and be a little more secluded. Then we could sit down next to each other and I could put my hand on his knee and say Oops! This isn't too close is it? Then when he says no I'll say "good because I really wanted to do this" as I slide my hand up his thigh and grab his big young cock. He gasps and I say "is this ok?" His face is white from the adrenaline going through him. He looks at me and then down at my hand stroking his manhood and says with a smirk "yeah of course" as I'm biting my lip from getting so turned on by his reaction. I continue to stroke it and say "wow you have such a big cock, I bet it tastes good too. Can I try?" while I'm pulling his shorts down to let that horse free. He's not resisting me so I just start to lick his shaft from the bottom up then twirl my tongue around that big head of his then gulp his dick and start sucking it. He let's out a little moan and my pussy gets wet at the sound of it. Then I moan a little while his dick is in my mouth and start sucking a little faster which turns me on more and I moan louder. I hear him whipser oh then my name which was so sexy. Makes me even more ready to ride his big young cock. I moan and suck a little bit longer before I jump on that dick and bounce on it. Up and down and ride him til I almost cum then stop. I get off him and bend over in front of him and say now pound that pussy. He grabs my hips and just starts fucking pounding away. It feels so good, his big cock going in and out of my wet ass pussy til finally I cum all over it...... if that really happened I wouldn't know what to do with myself.
