Haha good point there! xD
oh I thought it was pretty obvious that the sensei was lying? I mean the way sensei was kissing the guy wasn't very romantic and then when the college guy wanted to ask how is bf is like sensei automatically respondents with "itd be troublesome if he found out so come over as much as you like" even though the college guy promised to forget about the thing if he got one more bj (im pretty sure sensei is using the college guys assumption of that guy being his bf as a cover for sending more time with him)
okay but even if he told someone about what he saw it's not like he knew who the other guy was...so the other guy's reputation isn't at risk or anything lol
