(Her Secret Fantasy, continued by diddley...)

“I want to be fucked by your son,” says Rachel matter-of-factly.

“Who… but he even calls you Mom sometimes!” you reply, startled by her answer.

“Yeah, I’ve been watching him perv on me for a while and I overheard him talking to his friends on the phone a few days ago about me. Is this all okay?” asks Rachel.

“Well, it’s not what I had in mind, but if someone is gonna help him learn how to fuck, then you certainly can do that well!” you exclaim, as Rachel blushes. “So, how are you going to do this?”

“I haven’t made up my mind on anything yet,” says your girlfriend.

“Well, I’ve got a few ideas,” you add, “but I think the first thing to do is see what he thinks — if he is up for it or not.”

You call him. “Hello, is that you son?”

“Yeah Dad, it’s me. What’s up?”

“How do you feel about Rachel?” you nervously ask.

“She’s okay, I guess,” your son replies.“Why?”

“Do you think she is hot, would you fuck her?” you blurt out.

“Fuck Dad, where is this coming from? But yeah, I’d definitely fuck Rachel, even if she might be my step-mother someday. But I doubt that will ever happen,” he sighs.

“Well son, this is your chance. Rachel wants your cock and she wants it bad. Still wanna have a go at that pussy? If you do, you’d better get your little ass around here ASAP!”

As you hang up, you begin to process the events that just transpired. Rachel just told you her that she wanted to get fucked by your son, and you immediately rang him and he’s now on his way over.

“So Ross what did he say?” asks your girlfriend.

“He hung up and is on his way over right now. Are you sure about this, Rachel?” you ask her, as you feel the rising bulge in your shorts become harder to ignore.

She moves towards you and pulls down your shorts, releasing your erect cock. “Let me help you with that babe,” she coos as she takes you in her waiting mouth, tongue flicking your head as she moves up and down your shaft.

A few minutes feel like an eternity as she expertly licks and sucks you to the brink of cumming.

“Not yet, Ross, I’m gonna be getting off before you,” teases Rachel.

You can only grunt your annoyance as she runs her tongue over the tip and down to your balls.

Knock, knock.

It’s your boy. You stand there with Rachel there on all fours with her ass facing the door. Thoughts race through your mind as your son opens the door to see Rachel, her ass facing him as she continues to tease your manhood.

He freezes in the doorway.

“Well, aren’t you going to come in?” you ask him.
