I read this manga awhile back, but I can't seem to remember the name of it. I believe its about President and Secretary having a relationship. The president and his wife both have a lover of their own. The wife wants to have a baby so she need the husband's semen. The secretary and the president have sex to give the semen to the wife. But the semen turned out to be condense milk.

Mmmmm maybe this one? : http://www.mangago.zone/read-manga/aishite_baby/mf/v01/c004/2/
I'm looking for mangas about an introvert girl who never gets to have any fun as a student, and now that she's older she gets to try things she never did as a student (dating, going to amusement park) someone like that. I felt like I've read something like this before but can't recall.
