I prefer to share observations. Like “You are so wet and I love how you taste” or “I can feel your clit getting hard as you get more aroused” or “God your nipples are so hard, I need to suck them. Can I suck those hard nipples?”

I always want to bring the focus back to her and what I am noticing. I want to hear her desires and consent.

As she gets closer then I might say “I love to feel you cum”
