Jack Boldly Strides In

Jack slipped into his parents' room and paused for a moment, admiring the soft glow of the moon filtering in through the window. He could hear his father snoring softly, and the thought of waking him up just made Jack's heart race faster. He had never done anything like this before, but the idea of being his father's whore excited him more than anything else he had ever experienced.
Jack crept closer to his father's side of the bed and watched his chest rise and fall with each breath. He could feel his own breathing quickening as he reached out tentatively and trailed his fingers over his father's stomach, feeling the soft skin warm under his touch. The sensation made Jack's cock twitch in his shorts, and he found himself growing more and more aroused by the second.
Without warning, Jim's eyes opened and he looked directly at Jack, who felt himself freeze in place, wondering whether his father would be angry or repulsed by what he was doing. But instead, Jim just smiled and pulled Jack towards him, and whispered in his ear, "I knew you would be mine one day."
Jack felt shivers run down his spine as his father's rough fingers traced over his arms and shoulders, pulling him closer and closer until their bodies were pressed together. The warmth of Jim's skin was intoxicating and Jack could feel his own cock growing harder with each passing moment.
Jim kissed Jack's neck, his lips soft and firm against his skin as he trailed kisses down Jack's chest. Jack moaned softly, his body writhing with pleasure as his father's tongue licked at his sensitive nipples. Jim's hands moved down to Jack's waist, tugging at his shorts and pulling them down to reveal his hard cock, already slick with pre-cum.
Jim ran his hand down Jack's slick cock and he moaned lovingly. Jim leaned in for a kiss and their lips met. A jolt of electricity ran through Jack's body and he kissed Jim back just as passionately. Jim broke the kiss and whispered "I'm going to take care of you, baby." With that, Jim lowered his head to Jack's cock and began to lick up and down the shaft. Jack couldn’t believe that this was happening with his father.
But the overwhelming pleasure he was feeling made it difficult for him to think clearly. He was just completely lost in the moment. Jim's mouth worked expertly on his cock, leaving Jack gasping for breath as he squirmed with pleasure. Jim then paused and looked up at Jack, meeting his eyes with a look of pure lust and love.
As Jim continued to pleasure Jack's cock, he found himself getting lost in the moment, his thoughts drifting to his own father, Geoff. Suddenly, with a gasp, Jim moaned out "Geoff...". Jack's eyes widened, the realization of what Jim had just said hitting him hard. He looked down at Jim, who seemed completely unaware of his slip-up. Geoff was Jim's father, Jack's grandpa.
