It started as a typical Summer day in the Richter house. Travis sat on the couch playing Street Combat 64, a popular fighting game at the time. He was just about to reach the boss when his five year old son Lance entered the room. His nude form, an everyday sight in the house, offered little distraction to the focused eyes of his father, who only caught a glimpse of the boy out of the corner of his eye. "Hey champ, where's your sister?" Travis asked, knowing full well that Celia was at a friend's house that day. "I dunno," Lance said. The kitten walked over to the game system and plugged in a second controller before walking up to the couch. "Can I play too, Dad?" Travis sighed, but having beaten the game several times, he had no excuse. "Sure, kiddo," He said. With that, Lance hopped up on his father's lap, his naked rear positioned against the adult's groin as if on purpose. The two felines picked their characters and the battle started. Travis quickly won the first round, but then he noticed Lance starting to grind his hips and rub his young behind against the elder cat's pelvis. Nerves started to take hold of Travis as his penis started to stiffen and he tried to fight his arousal. He knew this was a tactic both his kids had learned to exploit, and he started to curse letting Lance up on his lap. Shortly after Lance took the second round, Vera walked up behind her boys, her stomach showing signs of another child on its way. She noticed what Lance was up to, and couldn't help but giggle softly as she walked up the stairs, trying not to be noticed. It wasn't long before Travis's penis was fully erect and straining against the underwear and jeans that tried desperately to hold it in. Travis knew he had to either adjust his pants or let his manhood free, and Lance wasn't planning on moving anytime soon. In fact the boy had stopped moving side to side and instead started going front to back. It was then Travis noticed that Lance had also become erect, and even took a moment or two to play with himself in between rounds. He knew this had to end sooner than later. Travis continued to struggle against Lance's assault, and he finally had enough. He set the controller down and pulled his son off of his lap. The boy protested for a moment, before he knew what his dad was up to. Quickly Travis removed his pants and underwear, leaving himself as naked as his son had been the whole time. He grabbed Lance's arm and directed the boy's hand to his penis. Lance instinctively started stroking his father's member before kneeling down between his legs. The boy licked his lips as he eyed the phallus in his hands, and couldn't resist giving it a lick. He heard a moan from his father and a hand stroke his hair, letting him know he was doing a good job. Lance opened his mouth and wrapped it around his father's manhood. His head bobbed up and down the shaft as he licked circles around the base of the tip. Soon, Travis pulled his son off of his groin. "Turn around," He said. Lance obeyed and stood up with his back toward his father. He felt hands grab hold of his hips and pull his body backward, where a large object met his sphincter. The shaft was already moist and slid in without too much resistance. Lance gasped and mewled, having not yet gotten completely used to the sensation. His body quickly relaxed as his thighs came to rest against his father's body. "Ready?" Asked Travis, to which Lance nodded in response. Travis grabbed Lance's legs just above his knees, pulling his legs up toward his chest and causing the kitten's back to rest against his father's body. Travis started moving Lance's young form up and down, the kitten's body impaled on his father's shaft. His legs were spread wide open and his own erection bounced as the action went on. Both the kitten and his father were moaning, gasping, and whispering to each other, their words only meant for the other to hear. Vera had moved back down the stairs and watched as her twin and their son shared a most intimate moment, their video game showing a 'Paused' screen. Part of her wished to join, but she decided it was best to let the boys bond. The boys took a brief break to turn Lance around so he was facing his father, his feet resting alongside Travis's hips and his eyes fixated on his father's. Lance now controlled the pace as he bounced his backside up and down. Now with a free hand, Travis started jerking off his son, making sure to please him as much as possible. As their mutual climax neared, the felines embraced in a passionate kiss before Travis unloaded his seed into his son. Shortly after Lance experienced his own orgasm as his body stiffened and his penis started to twitch, trying desperately to spew a liquid that wasn't yet being produced. They broke their kiss shortly after the orgasms, and they both started panting in an attempt to catch their breath. They were still unaware of Vera's presence, or the fact that Celia had come back home to get a few dolls to take back to her friend's house. The girls, however, decided that they wouldn't disturb the guys, and maybe they would have some fun of their own.
