What do you think is most important in sex? Looks, body type, cock size, hardness, stamina—there are many factors, but I truly believe the most crucial thing is "kissing skill." After all, sex almost always starts with a kiss. If the kiss fails, it's like a failed start. And women who have an erotic kissing face are highly likely to be incredibly sexy during sex. That's why today, I came up with a project: walking around the streets to investigate girls' kissing expressions. Among them, one girl caught my eye—Mai, petite with an adorable, small-animal-like face. When I asked her to show me her kissing face on the street, she shyly obliged, but it wasn't quite an erotic kiss yet. However, her potential was immense, hinting at a dramatic transformation. Moving to a hotel, we kissed through an acrylic panel, and soon her breathing turned heavy, moans slipping out as we progressed into deep, real tongue kissing. This was exactly the erotic kiss I'd been searching for! Mai's self-control shattered after the teasing, entering full-throttle overdrive mode from kissing alone. Honestly, she transformed so drastically it almost scared me! Turns out she's an incredible pervert! A girl with a boyfriend actually begging, "I want your dick"—unbelievable, lol. She seems to love looking at our joined bodies from underneath when I take her doggy style. So when I pounded her perfect ass hard, she squirted uncontrollably, climaxing with twitching spasms and a blissed-out "ahh" expression. She didn't just cum multiple times in missionary—she orgasmed repeatedly. I hope her boyfriend never finds out, lol. One last word to all men out there: if you want the best sex, master the art of kissing!
