"I think I'll turn your dad into a cock!" Luca said excitedly.
Luca felt a tingle run through his cocks at the though of Jeff's dad turning into a cock and being attached to his groin. Jeff's dad, Brad, is a very masculine man. In fact he's the perfect image of masculinity: large, muscular, hairy, handsome.
The most masculine part of Brad's body was his dick. Luca saw it once at a hotel pool. Jeff and Luca were on a school trip and Brad was a chaperone. After a dip in the hotel pool, Luca was changing in a stall when he peaked out and saw Brad changing out of his swimwear. His pendulous dick was swinging back and forth, slapping against his muscular thighs. He was definitely a shower! It looked to be more than six inches long and still completely soft.
Luca's cocks were rock hard thinking about Brad's dick. He heard Jeff moan in pleasure as Luca idly ran his fingers up and down his shafts.
"Fuck," he heard Jeff moan, "you definitely need to turn my dad into a third cock now. I knew dad was hung, but I didn't realize just how big he was. I know I should feel weird about it, but I guess since I'm your cock and you think my dad is hot, then I think he's hot too!"
Luca brought up Brad on the Chronivac and started typing.
"So what are dad's measurements?" Jeff asked as pre-cum leaked from his slit.
"Dunno," Luca said, "I didn't look. I want it to be a surprise. Hey, you think he should be in the middle? He's definitely bigger than the both of us, so I don't want to be...off balance."
Jeff moaned again. "Sure, whatever. Dude, just get on with it! I can't stand being teased like this!"
Luca finished typing. Jeff's dad, Brad, would become his third cock as an exact replica of his own cock except nestled between Luca's original cock and his Jeff-cock. Brad would be aware of the change but would think it was totally natural and would enjoy the experience.
Luca hit enter and watched the Chronivac progress bar quickly reached 100%. The Chronivac made a "ding" and after a few seconds of silence, Luca heard someone climbing the stairs.
