Just look him in the eye when sucking his cock and ask "Do I look good with your dick in my mouth?" Be confident. Own it.

I once dated an English girl who used to say the most ridiculously cute/dirty things to me, very matter of factly. It was the hottest thing especially in her accent.

>Please finger my arsehole, I want to feel more slutty
...while I was going down on her

>I love giving you blowjobs. You've got the nicest willy I've ever sucked.
...just out of the blue one day while we were doing nothing sexual

>Do you like my hairy cunt?

She was the most straight laced girl if you met her. Introverted, not into drinking and partying.

I think saying stuff confidently rather than tentatively is good advice, even if it sounds silly to you.

Really just start simple. You can just tell him what you'd like him to do you, or even just tell him how good you feel at the moment. It doesn't necessarily have to be dirty, even something like "take off your pants, I want to feel you inside of me" can be super hot. The more you do it the easier it gets.
