He tells Izzy to pull back the foreskin [smegma]

“You think that’s bad, sweetie? Pull back the foreskin…”

Izzy could feel her heartbeat in her own ears. Everything else fell away as her cock-addled brain slowly processed his words. This… wasn’t as stinky as it was going to get? Oh… oh fuck… umm…

She was cumming. She hadn’t even noticed when it started, and she was so stunned that nothing except her pussy had reacted. She let out a pathetic, strangled little whimper as her mind and body struggled to catch up.

Shaking like she was being electrocuted, Izzy moved her hands up her daddy’s shaft, to where the nearly apple-sized cockhead sat—over a foot from the base. His cock was erect, but only the very lips of his pisshole poked out of his foreskin. She gripped the folds of cock-covering. She started to drag it down slowly, but anticipation got the better of her, and Izzy found herself exposing his dickhead in one hungry tug. And... and... fuck!!!

Every crease, every dip, every surface of daddy’s cockhead was thick with slimy, chunky, off-white dick cheese!

Izzy’s mind shattered. Every thought in her head squirted out of her clenching teeny cunt along with a deluge of girlcum. The sight of her daddy’s smegma, the smell of it! Fishy, cheesy, cummy, sweaty, and overbearingly, unbelievably MANLY! It was like the pure essence of masculinity distilled down into a rancid sludge, and it caused little virgin brains to fry.

Izzy mindlessly fell forward. Her face rubbed into the foul cheese, and it reignited her crippling orgasm. She drooled and gurgled into her daddy’s nasty meat, neurons breaking one by one and being replaced by pure female instinct to serve stinky cock.
