When you hear them scream 'itai' once and have that grimacing look - then you'll know what it means. I te / Ita / Itai ( 痛い ) - 'It Hurts' or 'It's Painful' Most of the time, it is said in fast repetition.
Since it's always said at the end of the sex session. I think most of you guys can guess what it means anyway. Iku / Iki-sou ( 行く / 行きそう) - 'To Cum' or 'I'm Cumming' It also works as a question and as an answer, depends on the situation. It can be said in fast / slow / in a cry / screaming / high / low / in cute little sigh.
