Chapter One: Watching is fun.
The chubby brunette was going down on the skinny kid with a whole lot of enthusiasm, that much was for sure. Her mouth was going up and down the lad's modest-sized cock hard and fast, and I was so close to the action that I could see the saliva glistening on his shaft.
For his part, the boy was gripping the arm of the couch with one hand while running his other hand through the girl's hair, encouraging her to keep sucking him off. When he came, he let out a loud moan while his whole body spasmed. No need to be quiet, because there was nobody else in the house to hear him. His father wasn't due home for another hour.
That was what Chad had thought, but he was wrong. I had left home early and had peeked in the window to watch his pudgy little girlfriend gobbling his dick in the living room. I suppose that I could have turned around and went away for a while, or made a lot of noise to alert them, but I did neither.
Instead I watched. What's more, for better or worse, I liked watching them. A lot.

Chapter Two: Let me take you home.
Kelly was a real cutie. Chad had chosen well this time. Some of the girls he went with weren't all that great looking; for some reason he seemed to be attracted to these emaciated types that were androgynous and unappealing to me, but this Kelly was more my type.
Kelly was only about 5'2" or so, and by contemporary standards was probably about 15 to 20 pounds overweight, but there was no doubt she was a woman because she had the weight in the right place.
Not so much in the butt, which was nice and round but not overly large, or in the legs, which were shapely, but she sure had a lot up top, even if she didn't show it off much. Not nearly enough for my liking at least, as she seemed to wear tops that didn't show off what she had, but when I got glimpses, I could see she was one busty little babe.
Friendly too, in a shy way, and very polite and respectful to me when we were together. With Chad's mother out of the picture, there was only me around the house, so I got to see Kelly quite a bit. The more I saw her, the more I wanted her.
"I have to go to Kinko's to get some stuff copied and collated," I announced to the two of them, who were cuddling while watching TV. "If you want, I can take Kelly home."
Chad usually took Kelly home around this time, but his piece of crap car had been breaking down a lot lately, so I used that logic on them after he brushed me off initially.
"Look, I'll be ready to leave in about five minutes, so if you want me to take Kelly home for you, say your goodbyes now while I'm getting my stuff together."
"I could go with you two," my son Chad said.
"That's fine," I said with a smile. "You can help me at Kinko's, so instead of me being there for a couple of hours or so, it might only take me a little more than an hour."
I knew that would discourage Chad from joining us, and the look on his face confirmed my suspicions. They went out to the car while I pretended to get stuff ready to take with me. Peeking outside from my bedroom, I watched Chad and Kelly giving each other a lot of affection out in the driveway.
"That's it," I said to myself as I strained to see Chad's hands under Kelly's sweatshirt while they kissed. "Get her all hot for me, my boy."
I wondered what those tits would feel like. Was she wearing a bra? Probably, because she always seemed to be. Were they as big as I imagined them to be? She had to be at least a D cup. I pictured them to be full and a little spongy, and while I let my fantasies run wild, I re-positioned my stiffening cock inside my boxers before going outside.
"Ready?" I asked cheerfully, jingling my keys as I went to the car.

Chapter Three: Car troubles.
"This is real nice of you, Mr. Sheller," Kelly chirped as we pulled out of the driveway.
"No problem at all," I replied, feeling a little guilty about what I was about to do, but I was a lot more horny than guilty, and even the smell of the mint she was chewing on was getting me hot. "Oh-oh!"
As I said that, I turned off the headlights, tapped my foot on the brakes a few times, and swung off the road and into the parking area of the little pocket park at the end of the road.
"Oh no, not your car too!" Kelly said.
"What rotten luck," I said, looking over at my passenger, who looked cute even with the limited illumination of the street lights.
Hopping out of the car, I went out and popped the hood and looked inside. Kelly came out and joined me, peering into the darkness with me.
"Can't see much," Kelly offered, and as she leaned forward I came behind her and held her shoulders, inhaling the scent of her.
"I can see just fine," I whispered into her ear while moving up against her. "I could see the other day too when you were sucking my boy's cock."
Kelly's body jumped as I ground myself into her, and my hands left her shoulders and came around her, finding her harnessed breasts through the shirt with no problem.
"What are...?"
"You're quite the cocksucker," I hissed gutturally. "You looked like you knew what you were doing."
"I did," Kelly said in a quivering voice, and then shocking me by arching backwards toward me. "Sorry."
