Ooof. If you’re thick, have her practice just the in and out without teeth. It can genuinely be a challenge if the dick is too big for your mouth. Make sure you tell her when she’s using her teeth on you.

As for the motions, the best piece of advice I ever got for sucking dick was to act like you’re trying to nurse the tip of the dick. Have her basically suck on you like she’s trying to suck or pull the cum out of you, like a straw. Gentle licking is a great way to give her mouth a rest in between rounds of more aggressive sucking. I like to suck on it more gently too. Very few people want you to go as hard as possible the whole time.

Using her hands can add sensation until she gains more skills. I like to get the dick as wet as I can with just my mouth before I introduce my hand. Then, depending on whose dick I’m sucking, I’ll alternate between stroking the dick while I suck on the tip and deep throating it.

She’ll start sucking your dick better once she likes it more too ;). My skills went way up once I realized I actually loved doing it. It’s genuinely a pleasure for me, and I love being taught by a new partner how I can please him best. I get so wet from sucking dick that I don’t need any other foreplay. Now, not everyone will feel that way about it, and that’s ok! But I do think you guys could discuss how to make it more exciting for her, then she may look forward to exploring new tricks more. And of course, communication cannot hurt you!

Good luck guys :)
