I wanted to answer that in SM (or BDSM) play you can determine the limit of pain... when the dominating one is crossing it you can use predefinied word ( a 'safe word ') or sign to make the sadist decrease the limit of pain or to stop the sex.
Type in google: safeword Wikipedia . There will be more datailed explanation (⌒▽⌒).
Sooo sorry again. ......
He did cross the line. http://www.mangago.zone/read-manga/yoru_wa_tomodachi/uu/manga/yoru_wa_tomodachi/v01/c005/pg-21/ Right here.
Uhm... can someone explain to me what was this safe word and when the seme crossed the line? Sorry I didn't quite get it
