To Go All The Way With A Friend

I need to get married. But men aren't exactly lining up to meet me, and there aren't many prospects in this small town. Actually, there is one. My childhood friend, Cha I-hyeok. He whispers in my ear in a devilish tone. “I guess you don't have a choice, you'll have to marry me.” Is he a man? Sure. He's a good-looking guy, but we're like family. “Are you crazy? No. I can't marry you.” “Why not?” “If we get married, we'll have to do... things at night. How can we do that with you and me?” “Well, we can try it out.” “Try what?” “Kiss… or have sex.” Before I could scold him for his insanity, I-hyeok kisses my lips roughly. The moist, hot feeling is unfamiliar. His lips, nibbling on mine, swells slightly. And it's not just his lips that's swelling. I can feel him get hard, pressing against my flesh. “Huh....” We are friends. No… We were friends. Friends don't kiss like this. What are we now, then? (Source: Ridibooks, translated)
