Considering I've never thought about this before I'm surprised to say have to say I agree, now I think about it Dolly used to say jizz a lot in her videos and it doesn't seem right somehow. More British dirty talk please!
Fuck hole(s) is also a particular favourite of mine. erm.......
Spunk up my fuck hole.
Spunk on my tits, while i ram my fuck hole
My fuck hole wants your spunk.
Fill my fuck hole with your dirty spunk
OMG i can feel you so deep in my fuck hole and your jets of spunk hitting my cervix.
Stuff like that really.....
