If you’re new to talking dirty and feel shy about it start off small. Just getting into a girl’s ear and breathing heavily is a good start. Just whisper her name and say ‘fuck’ with emphasis on the CK. 

Only ever say things that are true and come naturally. Describing what you are doing, or are about to do is good for beginners. Here are some key words or phrases you can use:
- my hard cock
- your little pussy
- your perfect tits
- your soft skin
- never stop
- like that baby?
- I love it when you (describe what she is doing)
Timing is everything with talking dirty. You don’t want it to distract from the actual sex. Say little things during foreplay; get kinkier as the sex gets rougher.   
Some of my personal favourites:
- Your pussy tastes like candy. Please can I taste it. Just one lick? Please? 
- I want to stay in your pussy forever. I just want to live in your pussy and never leave. Can I just fuck you forever?
- Shhhhhhhh (while putting your hand over her mouth).
- Baby you are perfect. Your pussy is perfect. Your tits are perfect. Your ass is perfect. Your lips are perfect. Your eyes are perfect. You thighs are perfect. Your hands are perfect. Your neck is perfect. Your toes are perfect… (kiss each one after you tell her).
