i would say both in porn and real life "cum for me/in me" is the hottest thing i have ever heard. a womans body is a temple, and for her to say that is to me, the highest honor and hottest thing you can hear.
I like to say most of those things but if a guy has a small cock I am not going to say its big LOL then when people watch they will be like wtf? That cock is small!! I usually say what comes naturally such as for them to fuck me harder, I also like to use phrases that contain the word "fuck" ... I think fuck is my favorite word.
"I've been waiting to fuck you for so long now"
That would turn me off to even just think about during fucking..."baby batter" reminds me that there is sperm in that shit that could possibly knock you up and being as I do not want any other children I would just be like ummm no thanks ill go play with my toys! Even though I am on the pill, it still freaks me out to think of cum as "baby batter" no thank you!!"give me your baby batter" is refreshing every now and then
