I was out playing golf one Saturday morning about 3 months ago, when it starting raining pretty hard with some serious thunder and lightning, so I packed it in and went home. My wife and two smaller children were gone to the mall shopping and my oldest son, who is now 19, thinks he is independent enough, so he stayed home to play with his toy. That toy, of course, is his car. It is a '69 Mustang and he lives to wash and wax it, I think.
Anyway, when I turned the corner near my home, I noticed a strange car parked in front on the street, and my son's in the driveway, in the rain! Why did he not put it in the garage as usual, so it wouldn't get wet? I pulled in, put my clubs away in the garage and went into the house. I heard the TV coming from the back of the house so I went to see who was there with my son. I went down the hall and stopped at the corner of his door, not knowing who was there. If there was a problem, I wanted to be able to surprise them.
Well, I was the one to get surprised. There was Bobby on the floor on his back, naked, with a girl riding his cock like a race horse! And a XXX porn movie on TV! And the girl was making more noise now than the TV was. Obviously, she was about to cum! Being the good father that I am, I decided very quickly to let them finish before I let them know that I was there. She was pounding on Bobby so hard now that I wondered if she wasn't hurting him, since he was on the floor! And then Bobby started groaning and moaning and bucking under her and I knew both were cumming now. When they finally started slowing down, I started to say something, and then I realized that I had a hard on that was probably the hardest I had been in years! When the girl finished cumming, she just kind of rolled off to the side of Bobby there on the floor. When she rolled to the side, Bobby could (and did) see me standing at the door. But I was in such a state of shock, I couldn't say anything. The girl is the daughter of my wife's sister!!
Bobby yelled out "DAD!! What...Dad...I'm sorry Dad!! Where did you come from??"
Cindy (my niece's name) was up like a flash and trying to get her clothes and cover herself up. I said, "Son, don't try to explain, it'll just make you look stupid. Cindy, how long have you two been doing this? Bobby, your Mom is going to just die! And Cindy, you'll be grounded till after college! If your Mom even let's you go!!! And why did you pick 'home' to do this, why not out somewhere?" Bobby tried to say something, but Cindy beat him to it. She said "Uncle Joe, you just can't tell on us. You can't, please! It'll ruin us both! We just couldn't help it, we like each other so much it just seemed natural. Please Uncle Joe, I'll do anything you say if you just won't tell anyone about this. Please Uncle Joe!!"
And all the time she is talking, she is trying to find something, maybe her panties or something. And I realized while I was watching and listening, that this is one damned beautiful, sexy girl! I had never noticed that she was that sexy before! She even shaved her pussy!!! I said, "Cindy, how old are you now, 18...19? Let me think a minute, but get dressed girl! Bobby, you too!"
Cindy answered "I just turned 19, Uncle Joe." I stood in the doorway, so neither of them could leave, even if they wanted to. Then I said, "Cindy, I had not realized how beautiful you had grown up to be, and how sexy! And Bobby, I had no idea that you had grown such a good-sized cock on you. Cindy, before you put that shirt on, come over here a minute and let me see those gorgeous tits up close."
She hesitated a minute, just looking at me and then slowly walked over to me and arched her back to show how her tits would stand up.
I looked them over and said, "You know, you both should get a good whipping for this. But I guess you are too old for that. So what am I supposed to do with you two?"
Before Bobby could say anything again, Cindy chimed in and said "Anything Uncle Joe, anything you want to, but just please don't tell anyone else what we've done, Please. You can even whip us if you want to, but don't tell on us." I was beginning to think that Bobby was going to have a nervous breakdown, the way he was trembling. I had to do something quick. "OK, This is what it's going to be...(and I paused for a minute, letting that sink in)..how about we three have some fun together?" Bobby finally got to talk, "What do you mean Dad? We all three have some fun?"
"Well", I continued, "I think I would like to have a taste of this young pussy here!"
Cindy said "Anything Uncle Joe, You tell me what you want."
Bobby said "Dad, we're not!! Beat my ass but, me and you ain't playing!!"
I laughed and said "Not me and you son, shit! The three of us, and Cindy is probably going to have more fun than we do! Does that sound ok to you two? Oh yea, and one more thing, no one can ever hear about this β no one! Understand? If you don't think you can keep it secret, then we quit right now, right here! Agreed?"
Cindy chimed in first with "Whatever you want Uncle Joe. Anything, just ask, just don't tell on us! If you want me to have sex with you too, I will. I could give you a good fucking like Bobby just got. Just tell me what I have to do, OK?"
Then Bobby spoke up, "Like she said Dad, anything, just don't tell on us, and we'll keep it secret, too."
I said, "OK, this is our little secret till we die, understood?" They both agreed. Then I went on, "OK, let's all get undressed again, I think I want a taste of you Cindy! I mean a real taste!!" She nodded her head and ran off to the bathroom.
