what's your secret to give the best bj?

want to surprise my bf this coming new year and gusto ko siya bigyan ng something new like a new technique or smth.

tried asking sa friends kaso basic lang ang tips. tried watching videos kaso parang unrealistic or iisa lang ginagawa. learned and tried sloppy bj and so far bet na bet ng bf ko yon pero I wanna spice things up even more so.. naeenjoy ko rin pag ginagawa ko yun sakanya pero lately naprepressure ako kasi malapit na ako magkabraces and hindi ko alam paano ko na masusubo alaga niya pag meron kaya gusto ko sulitin

may tips or advices ba kayo when it comes to giving bj? ++ sa people with braces, paano niyo ginagawa magbj? wanna be prepared din hehe
