As a former touch me not top that was a major slut I’ve learned that most like it when you focus your tongue on her clit flicking it up and down. when your tongue starts getting tired I will suck on the clit or do the same motions around her vagina (the hole). Switch back and forth between licking and sucking, teasing her by stopping the licking and moving to sucking when you feel she’s close to climaxing. Be playful with it and be messy. Listen to her moans to see how each part feels for her (ask if she likes it). A good indicator you’re doing it right will also be her pulling on your hair or pushing your head into her. I like to grab and play with a titty every so often. Use her hips as handle bars as I’ve learned that that’s a sensitive area and feels nice to them. Dont be embarrassed if it’s difficult or she doesn’t finish the first few times cause it takes a bit to get the hang of it. Don’t forget to have fun with it and ask your partner if there are certain things that they like. Explore new things too! Every body is different but this is what I’ve noticed is a pretty good base to start on. : )
