It’s from Harsh Handjobs. He’s got a fairly tight foreskin but I don’t think there’s any particular timestamp to pick out. It’s the usual script where he gives the girls some cheek and they alternate between smacking his cock and jerking it.
“What do you do for a living?”
“I’m a film maker”.
“What sort of films do you make?”
“I annoy women and then they smack my cock until I cum”.
