“use your words” “you look so pretty when you’re desperate for me” “you make such pretty noises” “you’re being so good for me” “stay still and let me use you” AHHHHHHHH
If you're both into each other "Can I kiss you?" "Can I take your shirt off?" "Do you wanna do this?" Will NOT ruin the mood. Neither will "Do you like the way I'm doing this?" Consent is SO important, as is making sure the person you're with is actually experiencing pleasure.
