Probably not since Sasaki only promised to kiss him and won't do anything else's
But at the last pannel, you can see that their blazers are already gone!! It seems that Sasaki took it off LOL and I know, he said that he won't do it but I think he changed his mind? LMAO. At the end, he said, " ɪ ᴋɴᴏᴡ...ɪ sᴀɪᴅ ɪ ᴡᴏɴ'ᴛ ᴅᴏ ɪᴛ...ʙᴜᴛ–" GUYS there's a 'BUT' ☉_☉
Sensei is focusing more on thier emotional and both of them seemed fine the day after no cramps or body pain they probably just made out for a very long time or they just jerked each other off either ways they still haven't done it
so um did they do the thing at school?
