what did he mean by “the habit of putting your teeth up” how do you do that ?

I think it would be to open your mouth wider… That way your teeth aren’t in the way. If you find out let me know

Yeah, I was trying to figure out if he accidentally used teeth or if he was really good at keeping them out of the way.

You are so good! Thank you for clarifying ^_^

Like when u choke or get deepthroated, it’s a reflex of yours to curl up which makes your teeth sink down on the pp. which is especially painful on the bb when the mouth is being forced out (cause it’s getting scraped)

Yeah, I think the seme was pissed off that he discovered the main character knows to open wider so his teeth doesn't scrape his xxxx. He doesn't like the idea that the main character is already experienced in the ways of the gay smex.

Oh girl, I know. Lol
Also, sometimes the d is just too big.
And mafia daddy’s d....I mean you saw

Exactly. He said “who thought you”
