Jeff and Jack panted together as Jeff slid up the bed to lay next to his father. Jack's eyebrows were furrowed together, following Jeff's young body with a needy expression as his son settled in next to him and stroked his chest possesively
"Jeff! What's going on?? You're just so--" But Jeff put a finger to his father's lips.
"Quiet, dad, I'm resting. Bet you need to rest too from the two loads you spilled out of that tiny thing tonight."
Jack closed his eyes with a pained expression mumbling "But it's not supposed to be so small" but he obeyed.
Jeff turned to the mobile Chronivac modulator and opened his father's settings. He loved having his dad so needy and attracted to him! It seems like if just being attracted to Jeff put him under Jeff's control, Jeff wondered how much control he could really get over the burly man still recovering from his orgasm next to him. Jeff adjusted two things: first, he made himself a tiger in the sack, increasing his stamina and shortening his recovery time, along with a few tweaks here and there. Jeff had never really had sex before and he wanted to give himself a bit more experience. Second, he set Jack's horniness levels to slowly increase tenfold over the next ten minutes. With how head-over-heels Jack was for his son because of the last change, Jeff could only imagine how some added horniness would change his dad's demeanor.
The minute he submitted the changes, Jeff felt his new massive balls refill with cum, and his dick hang hot against his thigh. Jack has still trying to catch his breath with his eyes closed, mumbling softly. Jeff smiled wickedly and slapped his chest, and Jack's eyes flew open. He stared wide eyed up at his son leering over him, and Jeff felt totally possessive.
"You like me, huh Dad?" Jeff said, and Jack meekly nodded even through the conflict in his eyes, "Use your words." Jeff grinned.
"Yes, I like you." Jack whispered, he reached out to touch his chest, but Jeff batted the hand away.
"Nope, I didn't tell you you could touch me." Jeff said. Jack's eyes got wide, and he swallowed hard, Jeff noticed the tiny nub of his dad's dick getting hard again. "Put your hands underneath you so you don't get tempted again."
Jack awkwardly scooched around on the bed till he had pinned his own arms beneath him, sitting on his hands. This brought his chest to prominence as he breathed heavily, eyes still watching Jeff with a look of pure need. Jeff sat up to get a better look at his dad's body. He'd never seen it so taut and ready, so up close, so completely obedient to his own desires! His dad was a big man, tall with a huge chest covered in hair. Watching his stomach heave up and down with the exertion of ogling his son, Jack's toned abs from a life of careful weight training appeared and disappeared beneath his skin as the thick treasure trail down from his navel moved up and down. His arms and legs were thick and solid, and Jeff could see the striation in the muscle at his shoulders where his arms were pulled behind his back. And it was all Jeff's. Possibly literally, with the Chronivac, if he wanted.
"Tell me what you like about me, dad."
"Oh Jeff," Jack panted, as if he'd finally been allowed to breathe, "I... I love your chest, and your arms, I love the way you smile at me like that," Jack bit his lip and his back arched off the bed, pushing his tiny hard-on into the air. About 5 minutes had passed and he was unbelievably horny by now. And it would only get stronger. Jeff chuckled and maneuvered between Jack's legs, sitting back on his heels to reveal his rock-hard nine inches, fully recharged.
"And what about my cock? You like that?"
Jack nodded furiously them stammered to answer aloud "Yes! Oh god yes!" he whimpered.His body jolted again when Jeff took his dick between thumb and forefinger.
"I had no idea you had such a little penis, dad." Jeff said, pinching it a little.
"I didn't! I shouldn't I--" he gasped as Jeff rolled it between his fingers.
"Shhhhh. But you do. You have a tiny dick now, don't you?"
"...uh huh." Jack wailed, defeated.
"How long have you wanted me, dad?"
"I haven't! I mean.. I didn't... not until I saw you tonight when I noticed that I have a... a..." He swallowed and tried to close his eyes.
"...a what?" Jeff leered.
"A tiny penis."
"So, your tiny penis made you realize how much you want me, is that it?" Jeff said, and Jack looked confused for a moment, "Guess you're pretty glad about that tiny penis then, huh?" Jack nodded furiously again.
"Oh Jeff!" Jack's body was so alive with need for Jeff, but he didn't know for what, so he lay writhing on the bed, drinking in the sight of his dominant son, calling Jeff's name in an ever more needy whine.
"You want me don't you?"
"Yes! Please!"
"Have you ever been with a man before?"
"N-no."
"Did you like my tongue in your ass?" Jeff grinned.
"Y-yes! So much..."
"Where else do you want my tongue?"
Jack looked down at his hard tiny cock confused, but then stared at Jeff's monster dick and licked his lips. He looked like he had a revelation, and sheepishly replied:
"In my mouth?"
Jeff laughed and crawled slowly up his dad's bucking body, giving him a wet kiss on his father's masculine mouth. Jack moaned hoarsely around his son's tongue, feeling Jeff's big cock sliding over his tiny nub.
"I'm gonna fuck you now. And you're going to take it, right?" Jeff growled, and Jack practically began whimpering like a dog in need as Jeff's flaring head lined up with his hole.
