The other day my college-aged son asked me a very strange question. It was, "how can I make my GF cum?"

I was in shock! He's definitely old enough to know how to please a woman, especially a hottie like the one he's dating now. I tried giving a few pointers but it was clear that he wouldn't understand unless I showed him with an example.

He loved the idea, and even suggested that we get the GF involved. It seems she didn't take much convincing, either. The next day, the three of us met up at my place for our little demonstration.

As I requested, the GF was laying on my bed wearing nothing but lingerie. My boy had to sit on a chair nearby and was forbidden from touching himself or undressing. He did have a little pen and notepad to write on, though.

I got to hand it to him, he really did take a lot of notes and paid attention while I was explaining things. He even asked questions, despite clearly being uncomfortably horny. Only once did he ask permission to masturbate and his GF quickly reminded him, "your dad told you, you can only watch."

After that stern scolding, my son learned his lesson quick. Quietly, he saw me pound his GF's tight pussy and listenedd to her moan and beg. To be honest, I'm not sure why he had trouble with her at all. She was very vocal about what she wanted so it only took a while to make her cum.

Since we had time to spare, we fucked a couple more times. There was always another lesson to be learned, so we tried different things. I taught my son about anal, using toys, even a little bit about cumplay.

Did I get a little carried away with my lessons? Possibly. I mean, I have no doubt that my son learned something, I just worry that he wont be able to put it all into practice. When they left, I noticed he left his notepad. The last page read: "Forget it. Is it wrong if I prefer to watch?"

Crazy to think that my son might be a cuck but I got to accept him as he is. If that means being his bull, I would gladly do it to make him happy.
