There are two technical answers to this i guess, was during our first time, technically took it in my mouth, but it was more so just to get myself and him in the mood. the next day though, I went all the way in sucking him off. Like, straight up upto the knot. I felt it grow all the way to my mouth before sucking on it until he came down my throat and in my mouth.
The first time i did it, I was just doing it for my mood, the second time, when i did it proper, I wanted the intimacy basically. The first time turned me on.
Also, side note, people should research a lot before these, I'm lucky first time i didnt suck him all the way and chose to let him fuck me. I initially underestimated the Knot cause I didnt know it gets bigger when he's about to cum, nd dont wanna imagine getting knotted while he's in my mouth
