i once watched a jap porn with the storyline that a chio jap
babe work as pizza delivery, she went in the house and the guy was
naked, she kinda like it and give him the whole set of "special"
service. But too bad this kind of thing only happens in porn
stories.
back to your question, if they come in home delivery, do u want to
call? would u want to let the pros know where u live? And
neighbours may see differnt gals keep going your house, this would
create good gossip. i would rather not to call them home.
