At the time I hadn't even masturbated, so coming was totally unfamiliar. It was only after telling my buddies about the sensation I had experienced-kind of like the tense feeling you have when you're about to pee-that I learned that that was in fact an orgasm.
其實那之前我連自慰都沒有過，那天做到最後，我覺得好像快小便一樣，趕快跑去廁所，後來和同學討論後，我才知道那是高潮。
